[0025] Furthermore, the driving assembly 6 includes a cylinder 7, a fixed block 8, a connecting block 9, and a splint 10. The cylinder 7 is fixedly connected to the inner wall of one side of the outer shell 1, and the end of the cylinder 7 away from the inner wall of the side of the outer shell 1 is fixedly connected to the fixed block 8, the end of the fixed block 8 away from the cylinder 7 is fixedly connected to the connecting block 9, and the end of the connecting block 9 away from the fixed block 8 is fixedly connected to the splint 10.

[0026] Furthermore, the cylinder 7 includes a bottom plate 11, a driving cylinder 12, a top plate 13, and a support rod 14. The bottom plate 11 is fixedly connected to the inner wall of the housing 1. The driving cylinder 12 is fixedly connected to the outer wall of the bottom plate 11. The top plate 13 is fixedly connected to the output end of the driving cylinder 12. The output end of the top plate 14 is movably connected to the outer wall of the bottom plate 11. The output end of the top plate 14 away from the bottom plate 11 is fixedly connected to the outer wall of the top plate 13. The cylinder 7 is fixed to the inner wall of the housing 1 through the bottom plate 11. Each cylinder 7 is equipped with a connecting rod mechanism consisting of a fixing block 8, a connecting block 9, and a clamping plate 10. These driving components 6 are evenly distributed around the support sleeve 5 to ensure that the sleeve is evenly stressed during processing.

[0027] Furthermore, the clamping plate 10 is an arc-shaped plate that fits on the outer wall of the sleeve, and the clamping plate 10 is made of rubber.

[0028] Furthermore, a plurality of driving components 6 are arranged around the support sleeve 5 .

[0029] Working Principle: The sleeve machining fixture is first secured to the workbench via the mounting base 2. An internal retaining collar 4 is fixedly attached to the bottom inner wall of the housing 1, serving as a reference position for the sleeve. The drive assembly 6 includes a cylinder 7 and its accessories (fixing block 8, connecting block 9, and clamping plate 10). Cylinder 7 is secured to one inner wall of the housing 1 via a base plate 11. Each cylinder 7 is equipped with a connecting rod mechanism consisting of a fixing block 8, connecting block 9, and clamping plate 10. These drive components 6 are evenly distributed around the support sleeve 5 to ensure that the sleeve can be evenly stressed during the processing. The clamping plate 10 is designed as an arc-shaped plate that fits the outer wall of the sleeve and is made of rubber. This can provide sufficient friction when clamping the sleeve, preventing the sleeve from sliding or rotating during processing and avoiding damage to the sleeve surface. When the sleeve needs to be clamped, multiple cylinders 7 are started at the same time, driving the piston rod of the cylinder 12 to extend, pushing the top plate 13 to move toward the support sleeve 5. The movement of the top plate 13 drives the connecting block 9 and the clamping plate 10 fixed to it to move together. Multiple clamping plates 10 extend from the opening of the support sleeve 5, gradually approaching and clamping the sleeve. The rubber clamping plates 10 fit tightly against the outer wall of the sleeve and fix the sleeve in the fixture through friction. After the sleeve is fixed, subsequent processing operations can be carried out. After the processing is completed, the piston rod of the cylinder 7 retracts, driving the clamping plate 10 to retreat to the inside of the support sleeve 5, releasing the sleeve.
