[0053] Please refer to Figure 1 , the first lifting mechanism 12 and the second lifting mechanism 13 connected to the gantry support 11 are respectively used for driving the driven flange unit 14 and the active flange unit 15 to perform synchronous lifting action. The driven flange unit 14 and the active flange unit 15 are oppositely arranged, and a grinding and polishing tool, such as a rough grinding tool and a fine grinding tool, is arranged between the two. The two ends of the grinding and polishing tool are screw-connected to the driven flange 142 and the active flange 153. When it is necessary to adjust the angle of the grinding and polishing tool, the flange driving unit 151 is controlled to be started, the active flange 153 is rotated by a certain angle through the right-angle commutator 152, so as to realize angle adjustment of the grinding and polishing tool.

The protective cover plate 233 is additionally provided on the top of the first accordion protective cover 234 and the second accordion protective cover 235, which further improves the protective function of the protective cover, and the polishing waste accumulated on the protective cover plate 233 is also convenient to clean.

[0064] Please refer again to Figures 12 to 14 The workpiece clamping mechanism 300 includes a deflection base unit, a loading base unit 34 driven by the deflection base unit, and at least one set of chuck units 35 connected to the loading base unit 34. The chuck unit 35 includes a self-rotation driving module 351 for driving the chuck unit 35 to rotate synchronously with the workpiece 001. In this embodiment, the chuck unit 35 is provided with two sets, and the other set is a chuck unit 36. It can be understood that in other embodiments, the number of the chuck units 35(36) can be increased or decreased according to actual needs, and one workpiece 001 is fixed on each chuck unit 35(36).

When the connecting rod 353 is forced to move towards the top end of the chuck 352, the reverse tapered head 3531 is separated from the clamping blocks 3521, and the elastic member 354 is compressed under force, so that the plurality of clamping blocks 3521 shrink inward. Conversely, when the external force is released, the elastic member 354 pushes the connecting rod 353 to reset, so that the reverse tapered head 3531 expands the clamping blocks 3521. The length direction of the chuck 352 is internally provided with a through hole 3520, and the connecting rod 353 is arranged in the through hole 3520.

After the connecting rod 353 is released, the clamping blocks 3521 are expanded outward by the reverse tapered head 3531, so as to clamp and fix the workpiece 001 from the inside of the pipe cavity.

[0068] The chuck unit 35 further comprises a driving member 332 and a push plate 37 connected to the moving end of the driving member 332, and the push plate 37 abuts against the push rod 355. The driving member 332 can automatically push the push rod 355 up and down, synchronously driving the connecting rod 353 to move up and down, so as to realize the inward shrinking or outward expansion of the clamping blocks 3531, and facilitate the loading and unloading of the workpiece 001.

[0069] The loading base unit 34 comprises a box body 341, and the box body 341 is provided with a mounting cavity. The self-rotation driving module 351 is arranged in the mounting cavity, and the top of the box body 341 is provided with a top cover 342 for supporting and connecting the chuck unit 35.

[0070] AsFigure 11 As shown, the push plate 37 is above the top cover 342, the driving member 332 is connected to the bottom of the top cover 342, the moving end penetrates through the top cover 342 and is connected to the push plate 37, and the push plate 37 can synchronously drive one or more chuck units to perform workpiece taking and placing actions.

[0071] The shaft seat 356 is further arranged below the push rod 355, and the driving end of the self-rotation driving module 351 penetrates through the shaft seat 356 and is connected to the chuck unit 35. The shaft seat 356 is provided with a space for the lifting action of the push rod 355. In the embodiment, the self-rotation driving module 351 is a driving motor, and the driving member 332 is a pneumatic cylinder.
