[0036] To this end, in the embodiment, two opposite setting pneumatic cylinders 2 are taken as a group, and the technician can control two groups of pneumatic cylinders 2 to operate independently by external control switch or controller, so as to clamp the pipe body with rectangular cross section or other shapes, and the technician can also control two pneumatic cylinders 2 in a group to extend or shorten synchronously, so that the clamping jaw 4 installed on the sliding block 3 connected with the output telescopic shaft of the two pneumatic cylinders 2 moves synchronously to close or away, so that the two opposite setting clamping jaws 4 can be located at the center position of clamping end surface 11 when clamping the pipe body, to facilitate the pipe cutting machine control chuck to rotate to cut the pipe body.

[0037] It should be noted that in other embodiments, the pneumatic cylinder 2 can be directly fixed and installed at the clamping end surface 11.

[0038] Moreover, the technician can also rotate the lower end of the suction pipe 5 with the communication pipe of the external suction equipment, the suction equipment works to generate suction force to act on the end of the suction pipe 5 extended to the clamping end surface 11, and then to the clamped pipe body, and then the cutting debris generated at the cutting position of the pipe body during cutting is sucked to the suction pipe 5 along the inside of the pipe body, and then is sucked away from the chuck.

[0039] Further, please refer to Figure 3 , refer to Figure 3 As shown in the orientation, to further make the movement of the two opposite setting clamping jaws 4 consistent, in the embodiment, the two opposite setting clamping jaws 4 are taken as a group, and the technician can control the two groups of clamping jaws 4 to operate independently by external control switch or controller, so as to clamp the pipe body with rectangular cross section or other shapes, and the technician can also control the two clamping jaws 4 in a group to move synchronously, so that the two opposite setting clamping jaws 4 can be located at the center position of clamping end surface 11 when clamping the pipe body, to facilitate the pipe cutting machine control chuck to rotate to cut the pipe body. Figure 3Taking a set of cylinders 2 arranged along the front-to-back direction as an example, in addition to controlling the synchronous operation of this set of cylinders 2 through the controller, the technicians can also rotatably connect a synchronous gear 51 to the tube part of the suction tube 5 that extends into the inner cavity 14. Synchronous racks 21 are fixedly installed at the output telescopic shafts of the two cylinders 2 arranged opposite each other along the front-to-back direction. The synchronous rack 21 at the telescopic output shaft end of the rear cylinder 2 meshes with the synchronous gear 51 on the right side, and the synchronous rack 21 at the output telescopic shaft end of the front cylinder 2 meshes with the synchronous gear 51 on the left side. The two synchronous racks 21 are symmetrical about the center of the synchronous gear 51.

[0040] Thus, when a technician operates a set of cylinders 2 arranged in the front-to-back direction via a controller or control switch, the extension or retraction stroke of the two cylinders 2 is further limited by the meshing connection between the synchronous gear 51 and the synchronous rack 21, so that the extension or retraction distance of the output telescopic shafts of the two cylinders 2 is kept as consistent as possible, thereby enabling the gripper 4 driven by the two cylinders 2 to clamp the tube body more precisely at the center position of the clamping end face 11.

[0041] Additionally, please see Figure 3 , refer to Figure 3 As shown in the diagram, in this embodiment, a set of cylinders 2 arranged opposite to each other on the left and right are also provided with a synchronous rack 21 and a synchronous gear 51 between them and the suction pipe 5. The specific structural principle of the set of cylinders 2 arranged opposite to each other on the left and right, which is to move and limit the movement through the synchronous rack 21 and the synchronous gear 51 to keep the extension or shortening stroke consistent, is exactly the same as the other set of cylinders 2 arranged opposite to each other in the previous embodiment, so it will not be described in detail here.

[0042] In this embodiment, the synchronous gear 51 is rotatably mounted on the suction tube 5 via a needle roller bearing 52 to improve the rotational accuracy of the synchronous gear 51 and make the combined structure of the suction tube 5 and the synchronous gear 51 more compact.

[0043] Further, please refer to Figure 3 To facilitate the movement of the slider 3 and improve the sliding accuracy of the slider 3, a mounting seat 22 is fixedly provided at the end of the output telescopic shaft of each cylinder 2. The mounting seat 22 has a top mounting surface and a side mounting surface. The axis of the synchronous rack 21 is fixedly installed on the side mounting surface of the mounting seat 22. A rail mounting seat 23 is fixedly installed on the top mounting surface of the mounting seat 22. Two rail connecting grooves are opened on the rail mounting seat 23, which extend toward the center of the chuck body 1 and are parallel to the strip hole. A rail bar 12 is movably arranged in each rail connecting groove. The rail bar 12 is also fixedly installed on the inner end face of the plate where the clamping end face 11 is located.

[0044] Additionally, please see Figure 3Each slider 3 is provided with a sliding limit strip 13 on both sides. The sliding limit strip 13 is provided on both sides of the slider 3, and the sliding limit strip 13 is provided with a notch facing the edge of the slider 3 and the clamping end face 11. The two sides of the upper end face of the slider 3 extend into the two notches respectively, and are thus limited by the two sliding limit strips 13 to prevent the slider 3 from jumping up and down when sliding.

[0045] Further, please refer to Figure 1 , refer to Figure 1 As shown, a rotating gear 15 is also provided at the lower end face of the chuck body 1, and the central axis of the rotating gear 15 coincides with the central axis of the chuck body 1.

[0046] In response, when the technician rotates and installs the chuck body 1 onto the pipe cutting machine, the technician can also make the drive gear on the output rotating shaft of the motor mesh with the rotating gear 15, thereby driving the chuck to rotate, so that the chuck can drive the pipe body held by it to rotate, thereby improving the cutting efficiency and cutting quality of the pipe cutting machine.

[0047] Anything not mentioned above applies to existing technologies.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
