[0048] Working principle: chamfering the two side orifices of the ball valve core, the valve core can be put into the vibrating disc 3, and the valve core can be conveyed one by one along the conveying track 4 under the action of the vibrating disc 3, and the through hole of the valve core is parallel to the horizontal plane under the action of the vibrating disc 3, which is beneficial to subsequent clamping. By cooperation of multiple electric push rods 13 and small air cylinders 16, the valve core can be clamped by the clamping jaw 17 and the limiting column 18, and then the valve core is sent to the clamping assembly. By another electric push rod 13, the limiting block 19 is pushed to cooperate with the limiting block 19 on the front side of the top block 5, and the two limiting blocks 19 are combined to clamp the valve core. At the two side orifices of the valve core that need to be chamfered, the connecting rod 22 and the guide block 23 are used, and the air cylinder 9 pushes the clamping block 6 towards the valve core to ensure that the two grinding heads 20 are just abutted at the two side orifices of the valve core. After the motor 8 is started, the orifices of the valve core are chamfered. A vertical hole 27 is formed in the middle of the workbench 1 below the valve core.

When the two sealing plates 25 slide away from each other, the two arc-shaped scrapers 21 slide in opposite directions to scrape some debris around the vertical hole 27 into the vertical hole 27. The vertical hole 27 is connected with the discharge channel 10 and the waste channel 11. The sieve disc 26 is fixed in the middle of the discharge channel 10 and the waste channel 11. On the one hand, the debris remaining in the valve core falls on the sieve disc 26 under the action of gravity, and the debris is separated from the debris. On the other hand, the valve core can only slide out of the discharge channel 10 under the block of the sieve disc 26, while the debris passes through the sieve disc 26 and slides out of the waste box through the waste channel 11.
