Two cross blocks 9 are rotatably connected to two of the cross blocks 9. Two threaded sleeves 21 are fixedly connected to the outer side of two second worm gears 23. Two second worm gears 23 are meshed with the outer side of two second worm gears 24. Two connecting blocks are rotatably connected to the outer side of the top of two second worm gears 24. Two connecting blocks are fixedly connected to the outer side of two of the cross blocks 9. Two ring handles are installed at the top of two second worm gears 24. Two limiting rods 20 are fixedly connected to one side of two fixed blocks 19. The four limiting rods 20 are in pairs. The two sets of limiting rods 20 pass through two of the cross blocks 9 and are slidably connected to two of the cross blocks 9. Clamping blocks 25 are provided on one side of the other four cross blocks 9. Hydraulic rods 26 are fixedly connected to one side of the four clamping blocks 25. One end of the four hydraulic rods 26 passes through the other four cross blocks 9 and is fixedly connected to the other four cross blocks 9. An adjustment structure is provided between the multiple cross blocks 9.

[0023] The adjustment structure includes a rotating rod 13, which is rotatably connected to the bottom of the support platform 6. The bottom end of the rotating rod 13 is rotatably connected to the housing 1. A first worm gear 16 is fixedly connected to the outside of the rotating rod 13. A first worm 17 is meshed with the outside of the first worm gear 16. A support block 18 is rotatably connected to the outside of one end of the first worm 17. The support block 18 is fixedly connected to the bottom of the inside of the housing 1. A throttle handle is installed at one end of the first worm 17. The adjustment structure also includes an external gear ring 15, which is located outside the rotating rod 13. Multiple gears are provided between the external gear ring 15 and the rotating rod 13. A connecting post 14 is fixedly connected at both ends to an external gear ring 15 and a rotating rod 13, respectively. Six small gears 12 are meshed on the outer side of the external gear ring 15. A first threaded rod 10 is fixedly connected to the inner side of each of the six small gears 12. The bottom ends of the six first threaded rods 10 are rotatably connected to the housing 1. The top ends of the first threaded rods 10 extend into the cross groove 8. A cross block 9 is threaded to the outer side of the first threaded rods 10. An L-shaped plate 11 is rotatably connected to the outer side of each of the six first threaded rods 10. The top ends of the six L-shaped plates 11 are fixedly connected to the bottom of the support platform 6.

[0024] Specifically, when fixing a cylindrical workpiece, rotating the throttle engages the first worm gear 17 with the first worm wheel 16. The first worm wheel 16 drives the rotating rod 13 to rotate. The rotating rod 13 drives the external gear ring 15 to rotate through multiple connecting pins 14. The external gear ring 15 engages with six pinions 12. The six pinions 12 drive the six first threaded rods 10 to rotate respectively. Since the threads on two of the first threaded rods 10 are opposite to those on the other four, and two of the first threaded rods 10 are threadedly connected to two of the cross blocks 9, from... The two cross blocks 9 drive the two fixed blocks 19 to move downwards, so that the two cross blocks 9 and the two fixed blocks 19 are put into the two cross slots 8. The other four first threaded rods 10 are threadedly connected to the other four cross blocks 9 respectively. The other four cross blocks 9 drive the four clamping blocks 25 to move out of the other four cross slots 8 and adjust them to be above the support platform 6. Then, by activating the four hydraulic rods 26, the four clamping blocks 25 can fix the cylindrical workpiece, thus improving the stability of the cylindrical workpiece during processing.

[0025] When two of the cross blocks 9 are above the support platform 6, if a normal workpiece is to be fixed, the ring handle is turned, the second worm 24 and the second worm wheel 23 are engaged and connected. The second worm wheel 23 drives the threaded sleeve 21 to rotate. The threaded sleeve 21 is threadedly connected to the second threaded rod 22. The second threaded rod 22 drives the fixing block 19 to move. At this time, the two limit rods 20 on the fixing block 19 slide on the cross blocks 9, thereby fixing the normal workpiece through the two fixing blocks 19.

[0026] For the polishing structure 3, the polishing liquid spraying structure 4, and the dust collection structure 5, the scheme in the precision metal workpiece surface polishing equipment with publication number CN213319517U is adopted.
