Baffles 113 are fixed to the two sides of the support block 107, and the baffles 113 are in contact and sliding cooperation with the side of the conveyor belt 110 to prevent the balls from falling. A collecting bucket 112 is also fixed to the support block 107 to collect the balls that fall from the support block 107 and transport the balls to the ball placement pool 124 through the collecting bucket 112.

[0024] The working principle of a ball polishing device for bearings disclosed in the present invention is as follows: the balls to be polished are placed in a ball placement pool 124, and the air pump 128 is started. The air inlet of the air pump 128 will suck in external air through the air collecting hood 129. In this process, the air flow will drive the air wheel 130 to rotate. The air wheel 130 drives the input shaft of the second gearbox 133 to rotate through the second transmission belt 131. The output shaft of the second gearbox 133 will drive the feeding screw 127 to rotate. The feeding screw 127 transports the balls inside the ball placement pool 124 to the feeding pipe 125, and then moves to the inside of the acceleration tube 126. At the same time, the air outlet of the air pump 128 will blow air into the accelerating tube 126, forming a high-speed airflow in the accelerating tube 126. The high-speed airflow will drive the ball to move, and then collide with the fine sand inside the polishing pool 109, thereby realizing the relative movement of the ball surface and the fine sand, and then realizing polishing and grinding. The fine sand is mixed with some water to increase the fluidity of the fine sand (for the convenience of description, the axial length of the polishing pool 109 shown in the figure is not the actual length. After the ball enters the fine sand inside the polishing pool 109, it will sink to the bottom of the polishing pool 109 under the action of gravity). At the same time, the accelerating attraction electromagnet 123 can partially increase the speed of the ball movement. The main function of the accelerating attraction electromagnet 123 is to attract the ball that has entered the fine sand to move to the bottom of the polishing pool 109 (increase the movement speed).

[0025] Start the drive motor 104, the output shaft of the drive motor 104 will drive the rolling pulley 115 to rotate, and the drive motor 104 will also drive the input shaft of the first gearbox 105 to rotate, the output shaft of the first gearbox 105 drives the transmission connecting rod shaft 116 to rotate through the first transmission belt 108, the transmission connecting rod shaft 116 drives the toggle arm 117 to rotate, the separation lever 122 on the toggle arm 117 will follow the movement, the separation lever 122 will toggle the ball sunk to the bottom of the polishing pool 109 to rotate together, and then make the ball move to the sliding separation curved plate 120, and spirally slide upward on the upper surface of the sliding separation curved plate 120 until the ball Move to the top of the sliding separation curved plate 120 (at this time, the separation baffle rod 122 will contact the support block 107 magnetically, and then slide on the lower surface of the support block 107 until it is separated from the support block 107. Under the action of gravity, all the separation baffle rods 122 fall again, allowing the bottom end of the separation baffle rod 122 to contact and slide with the bottom surface of the polishing pool 109), and then fall on the sliding screen 119. The sliding screen 119 separates the balls and fine sand, and then rolls along the sliding screen 119 to the return pool 121, and energizes the traction electromagnet 106 to generate magnetic force, thereby attracting the balls on the sliding screen 119 to the surface of the conveyor belt 110. The rotating rolling pulley 115 will drive the conveyor belt 110 to rotate, and the rotating conveyor belt 110 will drive the balls to move, allowing the balls to move to the top of the conveyor belt 110 (the surface of the conveyor belt 110 is provided with a plurality of resistance bars for pushing the balls to move). When the balls move to between the baffles 113, that is, the position of the support block 107, there is no magnetic force at this position. Therefore, when the balls move to the position separated from the support block 107, they will fall into the collecting bucket 112 under the action of gravity, and then roll back into the ball placement pool 124. This cycle is repeated, and all the balls inside the ball placement pool 124 can be polished multiple times until they meet the requirements.
