Ball shoveling plate for processing G3-grade silicon nitride ceramic balls

Abstract

The invention discloses a ball shoveling plate for processing G3-grade silicon nitride ceramic balls. The ball shoveling plate comprises a ball shoveling plate body, the front side and the rear side of the ball shoveling plate body are clamped in an observation window of an upper grinding disc, gaps allowing the ceramic balls to pass through are formed between the left side of the ball shoveling plate body and the observation window and between the right side of the ball shoveling plate body and the observation window, and the upper surface of the ball shoveling plate body is sequentially provided with a slope face, a plane and a step surface. The lower surface of the ball shoveling plate body can abut against a lower grinding disc, an acute angle is formed between the slope face and the bottom face of the ball shoveling plate body, a plurality of protrusions are arranged on the plane, and the step face is lower than the plane. By means of the ball shoveling plate, the balls in the lower grinding disc can be evenly mixed through the protruding structures on the plane, the ceramic balls can randomly enter any channel every time the balls rotate by one circle, the channel stringing effect is improved, and therefore all the ceramic balls can basically pass through the machining paths with the same length, and the batch diameter variation of the silicon nitride ceramic balls is decreased; and the ceramic balls can indirectly enter the grinding channels through steps, and the self-rotation capability of the ceramic balls is improved.

Description

technical field [0001] The invention relates to the technical field of ceramic ball processing, in particular to a tackle plate for processing G3 grade silicon nitride ceramic balls. Background technique [0002] The processing of ceramic balls requires circular grinding in the grinding disc. Since the circumference of each channel is different, after the ceramic balls of different channels are ground for the same time, the variation in batch diameter varies greatly, so it is necessary to use a shovel The ball board scoops up the ceramic balls and enters different channels. When the currently disclosed tackle board is in use, the ceramic balls will move toward the outer channel after passing through the tackle board, while the inner channel rarely passes through the ball, and in severe cases, balls will be trapped, and the ceramic balls will enter the grinding continuously in a series Discs, balls and balls push and rub against each other, resulting in precision problems su...

Problems solved by technology

When the currently disclosed tackle board is in use, the ceramic balls will move toward the outer channel after passing through the tackle board, while the inner channel rarely passes through the ball, and in severe cases, balls will be trapped, and the ceramic balls will enter the grinding continuously in a series Discs, balls and balls push and rub against each other, resulting in precision problems such as large spherical errors, large dimensional tolerances, and large batch diameter variations of the processed silicon nitride ceramic balls. Therefore, there is an urgent need for a device that can make the processed silicon nitride ceramic balls Silicon nitride ceramic balls can be evenly arranged during processing, and appear in different channels with equal probability
