The conical grinding wheel 9 corresponds to the clamping and positioning assembly 18. The clamping and positioning assembly 18 plays a role in clamping and positioning the spring. The conical grinding wheel 9 can be detachably arranged on the chamfering and grinding assembly 19 through a limiting assembly 20.

[0025] The spring chamfering device includes a workbench 1, and also includes a sliding column 2 slidably arranged on the top of the workbench 1 in the left-right direction. A clamping and positioning assembly 18 is fixedly arranged on the top of the sliding column 2. A chamfering and grinding assembly 19 is fixedly arranged on the top of the workbench 1 and located on the right side of the clamping and positioning assembly 18. A conical grinding wheel 9 is detachably arranged on the chamfering and grinding assembly 19, so that the conical grinding wheel 9 corresponds to the clamping and positioning assembly 18. The clamping and positioning assembly 18 plays a role in clamping and positioning the spring. The conical grinding wheel 9 can be detachably arranged on the chamfering and grinding assembly 19 through a limiting assembly 20. During use, the spring is clamped and fixed on the clamping and positioning assembly 18, and then the chamfering and grinding assembly 19 is started, so that the chamfering and grinding assembly 19 drives the conical grinding wheel 9 to rotate. Then, the clamping and positioning assembly 18 is pushed, so that the clamping and positioning assembly 18 drives the spring to move towards the conical grinding wheel 9. Finally, the chamfering and grinding assembly 19 grinds the inner angle of the conical grinding wheel 9. By operating the limiting assembly 20, the conical grinding wheel 9 can be quickly detached from the chamfering and grinding assembly 19. By setting the clamping and positioning assembly 18, the spring can be clamped and positioned, thus compared with the prior art, solving the technical problems that the existing structure is not convenient to quickly replace, reducing the practicability, and being convenient to clamp and fix one end of the spring, resulting in certain limitations of the chamfering machine equipment.

[0026] Furthermore, the chamfering and grinding assembly 19 includes a cushion table 6 fixedly arranged on the top of the workbench 1, a grinding motor 7 fixedly arranged on the top of the cushion table 6, and a driving shaft 8 that rotates forward and backward through the grinding motor 7.

[0028] The limiting component 20 includes a mounting sleeve 10 movably sleeved on the driving shaft 8. The conical grinding wheel 9 is fixedly arranged at the left end of the mounting sleeve 10. The limiting component 20 further includes two shells 11 symmetrically and fixedly arranged at the upper and lower ends of the mounting sleeve 10. A slot 13 corresponding to the shell 11 is formed in the driving shaft 8. A plug rod 12 penetrating between the shell 11 and the mounting sleeve 10 and capable of being inserted into the slot 13 is arranged. A stop rod 14 fixedly arranged on the plug rod 12 is arranged inside the shell 11. A limiting spring 15 arranged between the stop rod 14 and the inner side wall of the shell 11 and sleeved on the plug rod 12 is used. By the elasticity of the limiting spring 15, the plug rod 12 is tightly pressed. During use, the two plug rods 12 are simultaneously pulled outwards to pull the plug rods 12 out of the slot 13. At this time, the mounting sleeve 10 is freed from limitation, so that the replacement of the conical grinding wheel 9 can be realized.

[0029] Further, the clamping and positioning component 18 includes a horizontal box 3, a clamping motor 4 fixedly arranged on the rear side wall of the horizontal box 3, an opening 16 formed on the right side wall of the horizontal box 3, a bidirectional threaded lead screw 17 penetrating through the rear side wall of the horizontal box 3 and rotating forward and backward by the clamping motor 4, and two arc-shaped plates 5 symmetrically penetrating through the opening 16 in the front and rear and simultaneously threadedly connected to the bidirectional threaded lead screw 17.

[0030] The clamping and positioning component 18 includes a horizontal box 3. A clamping motor 4 is fixedly arranged on the rear side wall of the horizontal box 3. An opening 16 is formed on the right side wall of the horizontal box 3.
