Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring processing, in particular to a grinding and polishing device suitable for bearing rings with different apertures. Background Art

[0002] Bearings are a crucial component in modern mechanical equipment. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. While bearings' true function should be considered support, literally, supporting the shaft, this is only part of their purpose. Support essentially involves bearing radial loads. They can also be understood as securing the shaft. This is covered in the "Quick and Easy Optimization" automated bearing selection guide. Bearings secure the shaft, restricting its rotational motion while controlling axial and radial movement. A motor cannot function without bearings because the shaft can move in any direction, while the motor requires only rotation. Theoretically, transmission is impossible. Furthermore, bearings can affect transmission. To minimize this effect, bearings on high-speed shafts must be well lubricated. Some bearings are pre-lubricated, but most require lubrication. Friction at high speeds not only increases energy consumption but, more importantly, can easily damage the bearings. The notion of converting sliding friction into rolling friction is incomplete, as some bearings require grinding and polishing equipment during machining.

[0003] In the bearing ring grinding and polishing device in the prior art, the fixing mechanism for fixing the bearing ring is usually fixed during actual use, and the sizes of bearing rings with different apertures are not consistent, which makes it inconvenient to grind and polish different gear rings, resulting in inconvenience during use. Therefore, we propose a bearing ring grinding and polishing device to solve the above-mentioned problems. Utility Model Content

[0031] As a preferred solution of the present invention, the positioning mechanism includes: a push plate 8, a connecting rod 9 and a transmission rod 11;

[0032] The push plate 8 is slidably connected to the left side of the cross plate 7, the connecting rod 9 is slidably connected to the left side of the cross plate 7, and the front side of the connecting rod 9 is fixedly connected to the rear side of the push plate 8, the transmission rod 11 is rotatably connected to the left side of the connecting rod 9, and the right side of the transmission rod 11 is rotatably connected to the left side of the positioning block 12. When the push plate 8 moves, the connecting rod 9 will be driven. At this time, when the connecting rod 9 moves, the connecting plate 10 will be driven to move backward. At the same time, when the connecting rod 9 moves, it will pull the transmission rod 11, and the movement of the transmission rod 11 will drive the positioning block 12 to move down. At this time, the positioning block 12 moves and disengages from the positioning groove, thereby unlocking the moving seat 6.

[0033] As a preferred solution of the present invention, a positioning frame 13 is fixedly connected to the left side of the horizontal plate 7, and the inner wall of the positioning frame 13 is slidably connected to the outer wall of the positioning block 12. The positioning frame 13 is used to conveniently limit the positioning block 12, so that the positioning block 12 can move stably vertically.

[0034] As a preferred solution of the present invention, a fixing frame 14 is fixedly connected to the left side of the transverse plate 7. The fixing frame 14 passes through the connecting plate 10.

The elastic force of the spring 15 facilitates the reset of the connecting plate 10.

[0036] As a preferred solution of the present invention, the bracket 2 is a hollow structure, and a connecting hole is opened on the inner wall of the bracket 2. The inner wall of the connecting hole is slidably connected to the outer wall of the movable seat 6, and the connecting hole facilitates the stable lateral movement of the movable seat 6.

[0038] The working principle of the present invention is as follows: in actual use, when the bearing ring needs to be polished, the bearing ring that needs to be polished is placed on the top of the bracket 2, and the inner wall of the bearing ring is fitted with the outer wall of the fixing seat 5. At this time, the push plate 8 is pushed to move backward. When the push plate 8 moves, it will drive the connecting rod 9. At this time, when the connecting rod 9 moves, it will drive the connecting plate 10 to move backward. When the connecting plate 10 moves, it will compress the spring 15. At the same time, the fixing frame 14 will limit the connecting plate 10, so that the connecting plate 10 can move forward and backward stably. At the same time, when the connecting rod 9 moves, it will pull the transmission rod 11. The movement of the transmission rod 11 will drive the positioning block 12 to move downward. At this time, the positioning block 12 moves and is out of contact with the positioning groove, thereby The movable seat 6 is unlocked, and the cross plate 7 can be pushed to move horizontally, thereby driving the movable seat 6 to move to the right. When the movable seat 6 moves to fit the inner wall of the bearing ring, by loosening the push plate 8, the spring 15 loses its restriction and pushes the connecting plate 10 forward. The connecting plate 10 moves and resets and drives the connecting rod 9 and the push plate 8 to reset. The transmission rod 11 is pushed by the connecting rod 9 to make the positioning block 12 move up and engage with the positioning groove to fix the cross plate 7, thereby fixing the movable seat 6. The bearing ring is supported and fixed by the cooperation of the movable seat 6 and the fixed seat 5. At this time, the electric slide rail 3 is started, and the electric slide rail 3 moves downward to drive the polishing machine 4 to move downward and contact the bearing ring. At this time, the polishing machine 4 can be started to polish the bearing ring.
