This application claims the benefit of co-pending US provisional patent application 5 No. 61 / 750,447, filed on January 9, 2013, the full contents of which are incorporated herein by reference.
Field of the Invention
The present invention generally relates to tube machining apparatus and, more particularly, to split frame pipe machining apparatus for machining large diameter pipes.
Background of the Invention
There are a variety of different types of tube machining apparatus to carry out various tube machining processes. One of these processes includes cutting tubes. Large diameter tubes can be cut with a split frame tube machining apparatus, which includes two frame halves that surround the tube from respective sides and fit together around the tube. This tube cutter includes a cutting tool or device that surrounds the tube and moves toward the tube in small increments during the cutting process to slowly cut the tube. Eventually, after many small increments of fit toward the tube, the tube will be completely cut.
Existing tube cutters can be large and have large profiles or thicknesses, thus limiting the environments in which tube cutters can be used. In addition, the cutting devices of

IMPI
MEXICAN INSTITUTE DB LA PROMSDAIi
INDUSTRIAL _ Existing pipes may not be used in environments that have low tolerance or small gaps between adjacent pipes. ~ ~
Furthermore, the frame sections of a split frame tube machining apparatus can be large and heavy components, thus making it difficult to separate the frame sections. The components used to couple and align the frame sections can be damaged when the frame sections are separated or assembled.
Split shell tube machining appliances can also be weak on the split lines due to the presence of the split line and the absence of structural support.

Detailed description of the invention
Referring to Figures 1-3, an exemplary embodiment of a tube machining apparatus 20 adapted for machining tubes of varying diameters is illustrated.
In some exemplary embodiments, apparatus 20 cuts completely through tubes. In other exemplary embodiments, apparatus 20 prepares one end of a tube for coupling to another tube. In still other exemplary embodiments, apparatus 20 both completely cuts off and prepares a tube for coupling to another tube. Apparatus 20 is adapted to cut tubes of a variety of different diameters such as, for example, approximately 152 centimeters, approximately 190 centimeters, approximately 229 centimeters, approximately 267 centimeters, approximately 305 centimeters, at least 152 centimeters, more than 305 centimeters, or any other tube diameter.
In the illustrated embodiment, the tube machining apparatus 20 is formed of four sections joined together 24A, 24B, 24C, 24D and includes a frame 28 and a tool carrier 32. The four sections joined together 24A, 24B, 24C , 24D together comprise frame 28 and tool carrier 32. A drive 34 is coupled to a periphery 35 of frame 28 and includes a pair of pinions 40A, 40b respectively coupled with a pair of drive motors 44A, 44B

suitable, such as an air motor with suitable gear reduction means. Frame 28 is adapted to engage and be fixed relative to a tube, and tool holder 32 can rotate relative to fixed frame 28 and tube. Motors 44A, 44B are adapted to rotate tool carrier 32 with frame 28 through a gear train.
The rotary tool holder 82 Includes one or more tool holders 48 (two tool holders 48 shown in the exemplary embodiment illustrated, which hold tools 52 to carry out a cutting or machining operation on the tube while the tools 52 rotate circumferentially around the tube Tool holders 48 are coupled to tool holder 32 by a plurality of fasteners 116. The machining operation carried out by tools 52 can form a straight edge substantially perpendicular to a longitudinal extension of the tube, a bevel at one end of the tube that is transverse to and is at an angle other than ninety degrees to the longitudinal extension of the tube, or a tube edge that has any angle.
With continued reference to Figures 1-3, it can be seen that the tool carrier 32 has a circular gear rack 56 to mesh with the pinions 40A, 40B coupled to the motors 44A, 44B. Thus, it can be seen that the drive motors 44a, 44B are adapted to rotate the tool carrier 32 relative to the frame 28 through a gear train provided with pinions 40A, 40B and circular gear rack 56 on the tool holder 32.
The apparatus 20 further includes a plurality of coupling elements 68 that can be coupled to an exterior of the tube and have adequate adjustability to couple and concentrically or axillately locate the apparatus 20 to the exterior of the
<img file="MX358908B_D0009.tif" />
tube. Coupling elements 68 can also be placed in apparatus 20 to couple an interior of the tube and are suitably adjustable to couple and concentrically or axially locate apparatus 20 within the tube.
Tool holder 32 is rotatably mounted on and supported by frame 28 by a plurality of roller bearings 72. Roller bearings 72 move in a circular bearing stroke 76 inside tool holder 32. An example of Stroke 76 and an example of roller bearings 72 can be seen in Figures 5 and 11.
Apparatus 20 also includes a feed mechanism 80 that is adjustable in and out of a path of a feed element 84 coupled to each tool holder 48 to advance tool 52 toward the tube.
With continued reference to Figures 1-3 and further reference to Figures 4-8, the tube machining apparatus 20 further includes a plurality of coupling mechanisms 88 positioned at the partition lines 108 where the four sections joined together 24A , 24B, 24C, 24D are spliced. Coupling mechanisms 88 assist in coupling the four sections 24A, 24B, 24C, 24D together and hold them together during operation of tube machining apparatus 20. In the illustrated exemplary embodiment, the tube machining apparatus 20 includes four coupling mechanisms 88, one on each divider line 108, to couple four sections 24A, 24B, 24C, 24D together. In other exemplary embodiments, the tube machining apparatus 20 may include a different number of sections and correspondingly include the same number of coupling mechanisms, one on each dividing line, to couple the sections together. Thus, it is understood that the tube machining apparatus 20 is capable of having any number of sections and any number of coupling mechanisms and still being within the spirit and

Four resistance elements 148 are included in the coupling mechanism 88 with a resistance element 148 placed on each side of a mass element 140 between the mass element 140 and an interior surface of slot 120. The resistance elements 148 provide enough friction or resistance to hold the coupling arms 128 in position under the force of gravity. That is, the coupling arms 128 will remain in place when released by a user and external force, such as that applied to a user, is required to move the coupling arms 128. This feature assists with coupling and decoupling of coupling mechanism 88 by keeping coupling arms 128 out of the way. The resistor elements 148 can be a wide variety of different types of resistor elements and can be made from a variety of different materials. In some exemplary embodiments, resistance elements 148 can be made of high carbon steel. Alternatively, resistance element 148 can be made of polyurethane or any other suitable material. The resistance elements 148 can also be generally flat or can be generally frustoconical in shape.

The coupling mechanism 88 further includes a pair of sleeve 168 with a sleeve 168 placed in each of the cavities 164. In addition, the first Base member 96 defines an opening 172 therethrough transverse to shaft opening 124 and positioned between the pair of grooves 120. Coupling mechanism 88 includes a separating element 176 positioned within opening 172 and which can move along and within opening 172. Shafts 132 are suitably dimensioned not to extend into opening 172 and engage or interfere with threaded fastener 176. In the illustrated exemplary embodiment, spacer element 176 is a threaded fastener that is adapted to screw-move along and within opening 172. Alternatively, the spacer element 176 may be a wide variety of other devices adapted to move in a variety of different ways and all of those possibilities are intended to be within the spirit and scope of the present invention.
With continued reference to Figures 1-8, the second base member 100 defines a pair of grooves 180 aligned with the grooves 120 on the first base member 96. The grooves 180 on the second base member 100 are adapted to receive the coupling arms 128 therein. The second base element 100 also defines a pair of cavities 184 in the joint surface 112 aligned with the cavities 164 defined in the first base element 96.

In addition, the second base member 100 defines an opening 204 therein aligned with opening 172 defined in the first base member 96. Opening 204 includes a first portion 208 having a first diameter and a second portion 212 having a second diameter less than the first diameter. Coupling mechanism 88 further includes a coupling element or cup 216 positioned within first portion 208 of opening 204. Coupling element 216
It includes a concave surface 220 on a surface thereof and defines an opening 224 therethrough in which a pin 228 is frictionally secured. The pin 228 is placed within and frictionally secured in the second portion 212 of the opening 204 for securing the coupling element 216 to the second base element 100. The coupling element 216 can be made of a wide variety of materials and is within the desired spirit and scope of the present invention. In some exemplary embodiments, the coupling element 216 can be made of bronze.
The coupling mechanism 88 can be moved between a coupled position and an uncoupled position. In the engaged position, the coupling arms 128 are pivoted down to place them in the grooves 120, 180 aligned with the adjustable coupling elements 136 screw-tight against a surface 232 of the second base element 100.

At this point, the two sections 24A, 24B of the tube machining apparatus 20 can be moved apart and moved to another decoupled position where the two sections 24A, 24B are completely decoupled from each other. In some cases, the tube machining apparatus 20 and sections 24A, 24B can be relatively heavy and there may be significant friction or separation resistance. Furthermore, it is desirable to move the two sections 24A, 24B generally straight away from each other and in a controlled and reliable manner at least until pins 188 substantially protrude from sleeves 168 to prevent deformation of pins 188. Conventional split shell tube machining apparatus have dowel pins that connect sections of the apparatus on the dividing lines and these pins are commonly bent or otherwise deformed when the sections are coupled together or uncoupled from each other.
Threaded fastener 176 and coupling element 216 of coupling mechanism 88 are provided to assist in separating the two sections 24A, 24B. Threaded fastener 176 is threaded into opening 172 to engage one end of fastener 176 with concave surface 220 of coupling member 216. Fastener 176 is threaded further into opening 172, thereby pressing against coupling member 216 and resulting in the two sections 24A, 24B moving apart as shown in Fig. 7.

In some cases, fastener 176 may be threaded until pins 188 are fully removed from sleeves 168. In other cases, fastener 176 may be threaded to begin removing pins 188 from sleeves 168 and then the separation of the two sections 24A, 24B may be completed in some other way. When the two sections 24A, 24B are reattached together, the fastener 176 should be retracted enough into the opening 172 so as not to interfere or engage the engagement element 216 and facilitate a tight splice of the first and second base member 96 , 100.
Referring now to Figure 9, one of the pins 188 secured to the second base member 100 is illustrated and described in greater detail. Pins 188 are substantially identical in structure and operation. Thus, only one of pins 188 will be described herein in detail with the understanding that the description and drawings included herein apply to all pins 188 of tube machining apparatus 20.
Pin 188 is generally cylindrical in shape and defines a groove or cavity 236 that surrounds pin 188 between first end 192 and second end 196. First end 192 is press-fit or otherwise secured by friction within the cavity. 184 in the second base element 100 and the second end 196 is removably received in the receptacle 200 of the sleeve 168 placed in the first base element 96. Slot 236 is closer to second end 196 than first end 192. Pin 188 includes a first angled portion 240 near first end 192 that is reduced in diameter as it approaches first end 192 of pin 188, and a first round portion 244 in the first
<img file="MX358908B_D0014.tif" />
End 192 of pin 188. Pin 188 also includes a second angled portion 248 that reduces in diameter as it approaches second end 196 of pin 188, and a second rounded portion 252 at second end 196 of pin 188. This configuration of the Second angled portion 248 and second round portion 252 acts as a guide as it is inserted into and removed from sleeve 168 to facilitate easier removal and insertion of sleeve 168.
Furthermore, in some cases, the two sections 24A, 24B may not separate from each other in a linear or straight manner, and the second angled portion 248 and the second rounded portion 252 conform to such a nonlinear separation. More particularly, the two sections 24A, 24B can be separated along an arched path rather than a straight one from the other. That is, for example, an outer edge 256 of the coupling mechanism 88 can be separated from an inner edge 260 of the coupling mechanism 88 at a greater amount or speed, thereby positioning the joint surfaces 104, 112 of the first and second elements. base 96, 100 at an angle to each other rather than parallel to each other during separation. In such a case, pin 188 will not be removed from sleeve 168 along a linear path. Rather, pin 188 will be rolled out or moved out of sleeve 168 along an arched path. The second angled portion 248 and the second rounded portion 252 of pin 188 allow pin 188 to move out of sleeve 168 along an arcuate path without significant interference or engagement with sleeve 168. Without the second angled portion 248 and the second rounded portion 252, significant engagement can occur between pin 188 and sleeve 168 potentially resulting in deformation or other damage to pin 188 and / or sleeve 168.

Tubes 20 includes a plurality of second coupling mechanisms 264 for coupling together the plurality of sections 24A, 24B, 24C, 24D. In the illustrated embodiment, the tube machining apparatus 20 includes four second coupling mechanisms 264 to couple the four sections 24A, 24B, 24C, 24D together. In other embodiments, the tube machining apparatus 20 may include a different number of sections and correspondingly include the same number of second coupling mechanisms to couple the sections together. Thus, it is understood that the tube machining apparatus 20 is capable of having any number of sections and any number of second coupling mechanisms and still being within the spirit and scope of the present invention.
The second coupling mechanisms 264 included in the tube machining apparatus 20 are substantially identical in structure and operation. Thus, only one of the second coupling mechanisms 264 will be described herein in detail with the understanding that the description and drawings Included herein apply to all second coupling mechanisms 264 of the tube machining apparatus.

The coupling arms 268 are adapted to rotate about axis 288. A single threaded clamp 296 can be threaded in and out of engagement with axis 288 to selectively prevent axial rotation and displacement of axis 288. In other exemplary embodiments, two shafts can be used in a manner similar to that incorporated with the first coupling mechanism 88. In these other embodiments, two threaded fasteners can be used to selectively engage the two shafts and prevent rotation and axial displacement of the two axes. Strength elements are located between hub elements 300 of coupling arms 268 and interior surfaces of grooves 272, 276 in a manner similar to first coupling mechanism 88 to achieve similar results.
The second coupling mechanism 264 also includes a base 304 coupled to frame 28 through dlvlsora line 108 by a plurality of fasteners 308, 312. In the illustrated embodiment, base 304 is coupled to frame 28 with four fasteners 308 , 312. Two fasteners 308 couple base 304 to one section 24A and two fasteners 312 couple base 304 to another section 24B. Alternatively, any number of fasteners can be used to attach base 304 to frame 28. By coupling base 304 through split line 108 in this manner, base 304 provides additional rigidity and strength to this side of apparatus 20 in the dividing line 108. Base 304 defines an opening 316 therein which includes a first portion 320 having a first diameter and a second portion 324 including a second diameter smaller than the first diameter.

The second coupling element 264 also includes a second base element 344 defining a threaded opening 348 therethrough and a separating element 352 positioned and movable within the threaded opening 348. In the exemplary embodiment illustrated, the spacer 352 is a threaded fastener that is adapted to screw-move along and within opening 348. Alternatively, the spacer 352 may be a wide variety of other devices adapted to move in a variety of different ways and all of these possibilities are intended to be within the spirit and scope of the present invention. The second base member 344 is coupled to the frame 28 with two fasteners 356 with the threaded opening 348 defined in the second base member 344 between the two fasteners 356. The threaded opening 348 and the threaded fastener 352 are aligned with the coupling element 328. The threaded fastener 352 and the coupling element 328 interact to assist in separating the two sections 24A, 24B in a manner similar to the threaded fastener 176 and the coupling element 216 of the first coupling mechanism 88. Before using threaded fastener 352 and coupling element 328 to separate the two sections 24A, 24B, the two fasteners 308 used to attach base 304 to section 24A must be uncoupled from frame 28 (the two fasteners on the right

Referring now to Figures 1, 2, and 12, the tube machining apparatus 20 is illustrated to include a low profile (ie, the apparatus is relatively thin or narrow when viewed from one side or end). The apparatus 20 is shown in Figure 12 with a plurality of installation tips 360 used during the assembly, installation and disassembly of an apparatus 20. The installation tips 360 are removed when installed on or attached to a tube. The low profile of the tube machining apparatus 20 provides the apparatus 20 with the ability to be used in low tolerance environments. Low tolerance environments may include, for example, small or narrow spaces, closely placed or densely packed tubes, or any other environments that do not have a significant space surrounding the tube to which the apparatus 20 is secured. The apparatus 20 includes a low profile since the components coupled to and extending from the tool carrier 32 and frame 28 do not protrude over a great distance. On one surface of the apparatus 20, the tool holder 48 is the element which protrudes the most from it and on the opposite surface the motors 44A, 44B extend the greatest distance from it. A thickness or profile of apparatus 20 can be defined between a surface 364 of tool holder 32 and a surface 368 of frame 28. In some exemplary embodiments, this thickness or profile may be approximately 12 centimeters. In other exemplary modalities, this thickness may be less than about 12 centimeters. In additional exemplary modalities, this thickness may be greater than about 12 centimeters.
