一种用于外径研磨的弹性环楔形钩胀紧装置及其使用方法
The elastic ring wedge hook expansion device, which uses a wedge hook in conjunction with an expansion screw and a tightening screw, solves the problems of radial misalignment of the elastic ring opening and poor roundness after expansion of the inner hole in outer diameter grinding. It achieves precise control of radial deformation and axial taper, expands the scope of application, reduces equipment cost and operation difficulty, and improves grinding accuracy and efficiency.

AI Technical Summary
In existing outer diameter grinding devices, radial misalignment of the elastic ring opening and poor roundness after inner hole expansion make it impossible to accurately control radial deformation and axial taper, limiting the scope of application. Furthermore, the equipment is costly and complex to operate.
The elastic ring wedge hook expansion device, which uses a wedge hook in conjunction with an expansion screw and a tightening screw, achieves precise control of the inner diameter of the elastic ring and adjustment of the inner hole taper through the micron-level gap fit between the wedge hook and the wedge hook mounting groove and the flexible hinge design of the U-shaped groove. The structure is simple and reduces equipment costs.
It significantly improves the accuracy and consistency of outer diameter grinding, solves the problems of radial misalignment of the elastic ring opening and poor roundness after inner hole expansion, expands the scope of application, reduces equipment costs and operating difficulty, and improves grinding production efficiency.
