[0026] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] Please see Figures 1 to 4 The present invention comprises a support 10, an inner support frame 20 detachably installed in the middle of the top surface of the support 10, a plurality of clamping components 30 evenly spaced on the outer periphery of the top surface of the support 10, and a plurality of docking components 40 evenly spaced on the outer periphery of the support 10.

[0030] The support 10 includes a generally circular carrier plate 11, a boss 12 protruding upward from the center of the top surface of the carrier plate 11, a plurality of hinge seats 13 evenly spaced on the periphery of the top surface of the carrier plate 11, a plurality of support arms 14 evenly spaced outward from the outer periphery of the carrier plate 11, a plurality of lugs 15 evenly spaced outward from the outer periphery of the carrier plate 11, and a pad 16 coaxially connected to the bottom surface of the carrier plate 11; the support arms 14 and lugs 15 are staggered, and the pad 16 is used to directly abut against the processing table.

[0031] Among them, such as Figure 3As shown, the boss 12 has a mounting hole 120 in the middle, which is an internally threaded hole. The mounting hole 120 is used for positioning and connecting the inner support frame 20. The lug 15 has a through hole (not shown in the figure), which is used for positioning and connecting the mating assembly 40.

[0032] In this embodiment, the support arm 14 corresponds one-to-one with the hinge seat 13, and the support arm 14 is located on the outside of the hinge seat 13 to facilitate the support of the connecting clamping assembly 30.

[0033] The inner support frame 20 includes a central block 21 with a detachable connecting boss 12, spokes 22 extending outward from the central block 21 at uniform intervals, and support blocks 23 connected to the ends of each spoke 22 respectively; the support blocks 23 are arranged in an arc shape and are used to abut against the inner wall of the pipe fitting to be processed, so as to improve the stability of clamping.

[0034] Specifically, the center block 21 has a central hole in its middle, which corresponds to the assembly hole 120. A bolt is inserted through the central hole and screwed into the assembly hole 120, thus achieving a matching connection between the inner support frame 20 and the support 10. In practical use, different specifications of the inner support frame 20 can be selected according to the inner diameter of the pipe to be processed.

[0035] The clamping assembly 30 includes a pressure block 31 and a cylinder 32 hinged to the top of the pressure block 31. The cylinder body of the cylinder 32 is mounted on the support arm 14. The piston rod of the cylinder 32 is used to hinge the top of the pressure block 31, while the bottom of the pressure block 31 is matched and connected to the hinge seat 13, so that the extension and retraction of the cylinder 32 can drive the pressure block 31 to flip along the hinge seat 13 to achieve clamping of the pipe to be processed.

[0036] In this embodiment, as Figure 4 As shown, the pressure block 31 is roughly arranged in the shape of a "7". The top of the pressure block 31 has a bent part 310 on the side facing away from the cylinder 32. The bent part 310 is used to abut against the pipe to be processed in order to clamp the pipe to be processed.

[0037] The docking assembly 40 includes a screw 41 for passing through the lug 15, a nut 42 connected to the top end of the screw 41, and an insert block 43 connected to the bottom end of the screw 41. Specifically, the screw 41 has a corresponding through hole, the nut 42 abuts against the top surface of the lug 15, and the insert block 43 is used to embed into the mounting groove of the processing table to ensure that the carrier plate 11 is tightly abutted against the processing table and to ensure the stability of the connection.

[0038] The above-mentioned machine tool processing table fixture has a simple structure and is easy to use. It can quickly clamp and fix the pipe to be processed using the inner support frame 20 and the pressure block 31. It is not easy to slip, has high stability, effectively reduces safety risks, and ensures processing accuracy and work efficiency.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
