Description

Technical Field

[0001] The utility model belongs to the technical field of bearing production, and particularly relates to a polishing machine for bearing balls. Background Art

[0002] A rolling bearing is a precision mechanical component that changes the sliding friction between a rotating shaft and a shaft seat into rolling friction, thereby reducing frictional losses. A rolling bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. The rolling bearing balls are made by one-time extrusion molding. Due to the defect of extrusion overflow on the outer side of the balls, they need to be polished.

[0003] In the prior art, a rolling bearing ball grinding and polishing device (patent publication number: CN220197178U) is disclosed. The balls to be polished are placed in a circular groove, and then the grinding disc is controlled to move downwards. The steel balls are ground and polished by the rotation of the grinding disc. In order to ensure that the steel balls will not break away during grinding, the steel balls will sink into the circular groove, which results in that after the grinding and polishing are completed, the steel balls can only be taken out one by one manually, and the discharging is cumbersome, affecting the polishing efficiency. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed for the present utility model.

[0019] Please refer to Figures 1-3 As shown in the figure, a polishing machine for bearing balls includes a workbench 1 and a chassis 13. A column 2 is vertically arranged at the rear side of the top of the workbench 1. Mounting plates 12 are symmetrically arranged on the upper surface of the workbench 1. The chassis 13 is placed at the central position of the upper surface of the workbench 1. Placing grooves 14 are evenly formed on the upper surface of the chassis 13. A convex block 15 is arranged at the front side of the chassis 13. The convex block 15 is rotatably installed between the two mounting plates 12. The whole chassis 13 can rotate around the rotation axis of the convex block 15. An arc-shaped support rod 16 is arranged at the rear side of the lower surface of the chassis 13. The arc-shaped support rod 16 penetrates through the workbench 1. The arc-shaped support rod 16 is concentric with the rotation axis of the convex block 15. By controlling the up and down movement of the arc-shaped support rod 16, the rotation of the chassis 13 is controlled, so that the chassis 13 remains horizontal during work and the rear side moves up during discharging to keep it inclined. A slope 161 is arranged at the front side of the bottom of the arc-shaped support rod 16. A convex platform 17 is arranged on the lower surface of the workbench 1. A slide rod 18 is slidably penetrated through the convex platform 17. An extrusion ball head 21 is arranged at the rear end of the slide rod 18. The extrusion ball head 21 is in contact with the surface of the slope 161. When the slide rod 18 moves backward, the slope 161 can be extruded by the extrusion ball head 21, so that the arc-shaped support rod 16 moves up, and then the chassis 13 is inclined to form a front-bottom and rear-high shape for easy discharging.

[0020] Please refer to Figure 2 As shown in the figure, a button 19 is arranged at the front end of the slide rod 18. The button 19 is placed at the front side of the workbench 1. A spring 20 is sleeved on the surface of the slide rod 18. The front end of the spring 20 is in contact with the button 19, and the rear end of the spring 20 is in contact with the front surface of the convex platform 17, so as to make the button 19 placed at the most front side by using the elastic force of the spring 20 and exceed the front end surface of the workbench 1, and no longer extrude the slope 161. At this time, the upper chassis 13 remains horizontal.

[0021] Please refer to Figure 1 As shown in the figure, a collecting groove 10 is horizontally formed at the front side of the upper surface of the workbench 1. An outlet 11 is formed at one side of the front end of the collecting groove 10. The outlet 11 penetrates through the front side surface of the workbench 1. A corresponding material box is butted outside the outlet 11 to centrally collect the polished steel balls.

[0022] Please refer to Figure 1 and Figure 2As shown, a slide groove 3 is vertically opened on the front surface of the column 2, and a threaded rod 4 is vertically installed inside the column 2 through a bearing. The threaded rod 4 passes through the upper surface of the column 2, and a hand wheel 5 is arranged on the top of the threaded rod 4. The threaded rod 4 can be controlled to rotate by the hand wheel 5 on the outside, thereby controlling the height of the lifting beam 6. A lifting beam 6 is slidably installed on the front side of the column 2, and the rear end of the lifting beam 6 is placed on the inner side of the column 2, and the rear end of the lifting beam 6 is screwed on the surface of the threaded rod 4, and a motor 7 is arranged on the front side of the upper surface of the lifting beam 6.

[0023] Among them, a grinding disc 8 is installed at the output end of the motor 7, and the grinding disc 8 is placed under the lifting beam 6, and the grinding disc 8 is placed directly above the chassis 13. The motor 7 drives the grinding disc 8 to rotate at high speed to grind and polish the steel balls. After the grinding disc 8 moves down, it contacts the steel balls. The outer protective ring 9 can be put on the chassis 13 to ensure the stability of the chassis 13. A protective ring 9 is set on the outer side of the bottom of the grinding disc 8, and the size of the chassis 13 is compatible with the opening size of the bottom of the protective ring 9.

[0024] The working principle of the utility model is as follows: by rotating the hand wheel 5, the threaded rod 4 is driven to rotate, and then the lifting beam 6 is driven to move up and down to control the height of the grinding disc 8. When in use, the chassis 13 is kept in a horizontal state, and then the steel balls to be polished are placed in the placement grooves 14 respectively, and then the grinding disc 8 is controlled to move downward so that the lower surface of the grinding disc 8 contacts the steel balls, and the grinding disc 8 is driven by the motor 7 to rotate at a high speed to realize the grinding and polishing of the steel balls, and the protective ring 9 is stuck on the chassis 13 to protect the interior. When the polishing is completed, The button 19 can be pushed backward to drive the boss 17 to move backward, and the spring 20 can be squeezed and force accumulated. When the boss 17 moves backward, the inclined surface 161 can be squeezed by squeezing the ball head 21, so that the arc support rod 16 moves upward, and then the chassis 13 is driven to rotate around the center of the protrusion 15, so that the chassis 13 is tilted, making the chassis 13 lower in front and higher in the back, and then it is convenient to pour out the polished steel balls, and roll them into the collecting trough 10, and then flow out through the discharge port 11. After a single use contact, the chassis 13 is returned to its original position by its own weight and the force accumulated in the spring 20.

[0025] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
