The counter cone 101 is in fitting connection with a pillar body 103; the processing lathe 1 is a prior art, including a control panel part, which can control the forward and reverse rotation of the servo motor 204.

[0028] Above the pillar body 103, a grinding assembly 2 is provided. The grinding assembly 2 includes a screw rod bin 201 fixed to the top of the processing lathe 1. A threaded rod 202 is rotatably installed inside the screw rod bin 201. A threaded sleeve 203 is threadedly slidably connected to the threaded rod 202. The bottom of the threaded sleeve 203 is fixedly connected to a connecting plate 206, and the connecting plate 206 is slidably connected to the bottom of the screw rod bin 201; among them, a moving sleeve 205 is sleeved on the outer wall of the pillar body 103. The top end of the moving sleeve 205 is fixedly connected to a T-shaped block 208, and the T-shaped block 208 is snap-fitted with the connecting plate 206; among them, a fixing mechanism 3 is provided at the piston rod end of the telescopic rod 102.

[0029] A T-shaped groove 207 is opened at the bottom of the connecting plate 206, and the T-shaped groove 207 is snap-fitted with the T-shaped block 208. Through sleeves 209 fixed to the surface of the connecting plate 206 are provided on both sides of the T-shaped groove 207; the T-shaped groove 207 is a kind of recessed groove, and the inside of the T-shaped groove 207 can provide support for the T-shaped block 208.

[0030] An insertion plate 210 is connected through the through sleeve 209. One end of the insertion plate 210 is fixedly connected to a limiting strip 211. A stabilizing bolt 212 is threadedly connected to the middle of the limiting strip 211. A through hole 213 is opened at the end of the insertion plate 210 away from the limiting strip 211, and a through hole 213 is also opened on the through sleeve 209 away from the limiting strip 211. A limiting pin 214 is connected through the through hole 213; the stabilizing bolt 212 can squeeze the T-shaped block 208, so that the T-shaped block 208 is stably embedded in the T-shaped groove 207, reducing the shaking of the T-shaped block 208.

[0031] The top surface of the limit pin 214 is slidably connected with a movable bar 215, and the bottom end of the movable bar 215 is inserted with a micro socket 216 installed on the surface of the through sleeve 209; after the movable bar 215 is inserted into the micro socket 216, it can prevent the limit pin 214 from sliding out of the through hole 213.

[0032] A servo motor 204 is fixedly installed outside one side of the processing lathe 1. The output end of the servo motor 204 extends into the screw rod bin 201 and is fixedly connected with the threaded rod 202. The inner side of the moving sleeve 205 is fixedly connected with a polygonal grinding ring 217, and the polygonal grinding ring 217 is attached to the outer side of the pillar body 103; the polygonal grinding ring 217 can grind off the protrusions and sharp edges on the surface of the pillar body 103. The servo motor 204 cooperates with the control panel to control the distance that the threaded sleeve 203 drives the moving sleeve 205 to move each time.
