The fixing component 4 includes an inner ring 43 fixedly installed inside the workbench 2, an adjusting gear disk 42 rotatably connected to the workbench 2, and a rotating motor 41 fixedly installed inside the base 1. The rotating motor 41 is rotatably connected to the adjusting gear disk 42. An adjusting rack 46 that is slidably connected around the inside of the workbench 2 and slidably connected to the inner ring 43 is arranged inside the workbench 2. The top end of the adjusting rack 46 is fixedly installed with an outer clamping block 47 for clamping. An adjusting gear 45 that is rotatably connected to the workbench 2 and meshes with the adjusting gear disk 42 and the adjusting rack 46 is arranged inside the workbench 2. The clamping component 3 includes a driven gear 35 rotatably connected to the inside of the workbench 2, a driving gear 33 meshing with the driven gear 35, a rotating main shaft 32 fixedly installed with the driving gear 33, and a rotating motor 31 rotatably connected to the rotating main shaft 32. An adjusting groove 36 for adjustment is formed around the top end of the driven gear 35. A connecting rod 37 is slidably connected to the inner side of the adjusting groove 36. The top end of the connecting rod 37 is fixedly installed with a connecting plate 38. The top end of the connecting plate 38 is fixedly installed with an inner clamping plate 311 for clamping.

[0023] Referring to Figures 1 to 5 , a rotating shaft 44 rotatably connected to the workbench 2 is fixedly installed inside the adjusting gear 45. A rotating shaft 34 rotatably connected to the workbench 2 is fixedly installed inside the driven gear 35.

[0024] Referring to Figures 1 to 5 , a slide bar 310 slidably connected to the connecting plate 38 is fixedly installed on the inner side of the top end of the workbench 2, and the slide bar 310 is symmetrically and fixedly installed on the inner side of the workbench 2. The slide bar 310 is also fixedly installed on the top end of the inner ring 43.

[0025] The working principle of the present utility model is as follows: When positioning and clamping the annular member for processing, first, the workbench 2 is powered on, and then the annular member is placed on the top end of the workbench 2. Then, the operator starts the external controller to start the rotation of the rotation motor two 31 to drive the driving gear 33 to rotate. At this time, the driven gear 35 meshed with the driving gear 33 rotates together. With the rotation of the driven gear 35, the connecting rod 37 slides and adjusts inside the adjustment groove 36. Through the sliding adjustment of the connecting rod 37, the connecting plate 38 can be driven to slide on the top end of the workbench 2, and the inner clamping plate 311 is driven to clamp and position the inner wall of the annular member. Then, the operator starts the rotation motor one 41 to work through the external controller. Through the rotation of the rotation motor one 41, the adjustment gear disk 42 can be driven to rotate inside the workbench 2. With the rotation of the adjustment gear disk 42, the adjustment gear 45 rotates, and then drives the adjustment rack 46 to slide inside the workbench 2, and drives the outer clamping block 47 to approach and fix to the outer wall of the annular member. Through the fixing assembly 4 and the clamping assembly 3, the inner wall and the outer wall of the annular member can be clamped and positioned together, reducing the shaking of the annular member during the processing, increasing the stability of the annular member processing. At the same time, the outer clamping block 47 and the inner clamping plate 311 being in the same direction can make the clamping and positioning force in the same direction, increasing the stability. And the wear-resistant pads 312 at one end of the inner clamping plate 311 and the outer clamping block 47 can increase the clamping friction force, effectively preventing the annular member from sliding during the work process, and improving the clamping stability.
