[0040] Please see Figure 3 The transmission assembly includes a transmission rod 12 and a slide bar 13. There are two transmission rods 12 and two slide bars 13. The bottom ends of the two transmission rods 12 are hinged to the left side of the transmission wheel 11, and the top ends of the transmission rods 12 are hinged to the bottom ends of the slide bars 13. The two ends of the bottom of the chain 14 are bolted to the top of the two slide bars 13 respectively.

Example

[0044] The difference between this embodiment and Embodiment 1 is that the electric push cylinder 9 and the hinge rod 10 are replaced with a geared motor. The geared motor can directly drive the transmission wheel 11 to rotate. However, the control requirements of the geared motor are too high, which can easily increase the cost. Therefore, the electric push cylinder 9 and the hinge rod 10 are preferred in this application.

[0045] It should be noted that the specific model of grinding motor 3 and electric pusher cylinder 9 to be used is to be selected by those skilled in the art. Furthermore, the grinding motor 3 and electric pusher cylinder 9 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0046] The working principle of this utility model is as follows: Steel balls and abrasives are poured into the grinding disc 5 inside the bearing steel ball grinding cylinder 1. The power supply of the grinding motor 3 is turned on, which drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the grinding disc 5 to rotate. The grinding disc 5 and the convex strip 6 cooperate to drive the abrasives and steel balls to move. The steel balls roll in the abrasive. The abrasive particles in the grinding medium have high hardness and sharp edges. When the steel balls roll in the grinding medium, the abrasive particles will embed into the surface of the steel balls to a certain depth and cut the surface of the steel balls under the action of friction, removing the metal material from the surface of the steel balls, thus achieving the grinding process of the steel ball surface. The size, shape, and hardness of the abrasive particles have an important influence on the grinding effect. Generally speaking, the smaller the particles, the lower the surface roughness of the ground steel ball; the higher the particle hardness, the stronger the cutting ability and the higher the grinding efficiency. By selecting appropriate abrasive particles, steel ball grinding processes with different precision requirements can be met. The frame 7 and base 8 support the bearing steel ball grinding cylinder 1. After grinding, the power supply of the electric push cylinder 9 is turned on. The electric push cylinder 9 is controlled by a controller. The electric push cylinder 9 can drive the hinge rod 10 to move downward. The hinge rod 10 and the transmission wheel 11 are eccentrically connected, so that the hinge rod 10 can drive the transmission wheel 11 to rotate. The transmission wheel 11 and the transmission rod 12 are eccentrically connected, and the two transmission rods 12 are set at different heights. The transmission wheel 11 can drive one of the transmission rods 12 to move downward and the other transmission rod 12 to move upward. The transmission rod 12 can drive the slide bar 13 to move. The chain 14 has a U-shaped structure to facilitate transmission. The chain 14 can drive the transmission sprocket 15 to rotate. The transmission sprocket 15 can drive the bearing steel ball grinding cylinder 1 to rotate, so that the opening of the bearing steel ball grinding cylinder 1 is tilted. The cover plate 16 is opened, and the container with the filter screen is placed on the base 8 to receive the abrasive and steel balls poured out of the bearing steel ball grinding cylinder 1.
