The diameter of the installation groove is larger than the outer diameter of the valve core, and at least three through holes are evenly opened circumferentially on the valve core fixture towards the outside of the valve core fixture. Threads are provided in the through holes, and bolts are arranged to match the through holes. The bolts pass through the through holes to clamp and fix the valve core, and the grinding plate is movably arranged on one side of the valve core. The utility model uses the electric drill to connect the valve core fixture to clamp and fix the valve core, and rotates the valve core by controlling the rotation of the electric drill to achieve the effect of rotating the workpiece on the lathe, overcoming the difficulties of manual grinding in terms of unable to master the angle and inconvenient fixation, and realizing self-grinding and polishing of the valve core, thereby reducing the time of external repair and the maintenance cost.

[0004] Although the above valve core grinding and polishing device can overcome the difficulties of manual grinding in terms of unable to master the angle and inconvenient fixation, the above valve core grinding and polishing device still requires manual operation by workers to polish the valve core of the ball valve during work. Since manual polishing cannot master the polishing force and the polishing angle, difficulties may occur during polishing, resulting in unevenness on the inner wall of the ball valve. Therefore, a ball valve polishing device with strong stability is proposed. Content of the Utility Model

The other end of the first rotating shaft 202 is fixedly connected with a ball screw 203. The outer wall of the ball screw 203 is engaged with a ball nut 204. The top of the ball nut 204 is welded and connected with a moving block 205. The back of the moving block 205 is welded and connected with a bracket 206. The top of the bracket 206 is threadedly connected with a threaded rod 207. The top of the threaded rod 207 is welded and connected with a turning block 208. The bottom of the threaded rod 207 is movably connected with a bearing 209. The bottom of the bearing 209 is fixedly connected with a clamping block 210. The bottom of the clamping block 210 is adhesively connected with an anti-slip pad 211. The top of the moving block 205 is movably connected with a ball valve body 212.

[0028] Among them: During the process of the stabilizing mechanism 2 stabilizing the ball valve body 212, first place the ball valve body 212 in the upper slot of the moving block 205, and then rotate the turning block 208 clockwise.

Then start the servo motor 305. The servo motor 305 drives the polishing disc 307 to rotate through the second rotating shaft 306. At this time, the ball valve body 212 moving to the left is inserted into the polishing disc 307 to polish the ball valve body 212. This is the working principle and working process of the ball valve polishing device with strong stability.
