Technical Field

[0002] A bearing is an important component in mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. During the bearing processing and production process, the outer and inner surfaces of the bearing inner and outer rings are usually ground to ensure the smoothness of the surface.

[0003] The utility model with the publication number CN210435953U discloses a grinding device for bearing processing. Through the counterclockwise rotation of the second servo motor, three adjusting columns are driven to synchronously move towards the center of the turntable, thereby clamping the outer surface of the bearing ring. Then, through the operation of the first servo motor, the bearing ring is driven to rotate. Through the clockwise rotation of the third servo motor, the fixed block and the side block are driven to rotate clockwise until the second grinding disc is adjusted to the exact right side of the bearing ring. Through the extension of the telescopic end of the second electric push rod, the second grinding disc is pushed to move to the left until it is adjusted to the inside of the bearing ring, and the height of the second grinding disc is adjusted through the telescopic movement of the telescopic end of the hydraulic pump.

In the past processing of bearings, during the grinding process, the bearings will lean against the surface of the grinding equipment for a long time, which will cause local areas of the bearings to overheat due to long-term friction, and will also cause vibration accumulation, affecting the processing accuracy of the bearings. During the operation of this equipment, after the bearings are fixed, the user can control the driving equipment at the bottom of the base 1 to drive the anti-disengagement rod 6 to rotate. First, through the linkage transmission of the transmission bevel gear 9, the first bevel gear rod 10, the driven bevel gear 11 and the second bevel gear rod 12, the accessories connected to the bearings will be controlled to move. At the same time, the eccentric block 8 will also rotate periodically. During this process, when the protruding part of the eccentric block 8 approaches the extension frame 13, the cushion wheel on its surface will come into contact and be pushed, thus acting in the opposite direction on the surface of the neutral plate 3. Affected by the anti-disengagement rod 6, the neutral plate 3 will move horizontally. For the first socket 15 accessories connected to the neutral plate 3 and the side support 4, the user can rotate the inner rotary sleeve 16 in advance to make the threaded rod 17 rotate inside it. And the docking sleeve 20 connected through the threaded sleeve 19 will move along with it. The clamping cover 22 will be restricted and will move inside the docking sleeve 20 in cooperation with the slots 21. As the first spring 24 moves, it will start to store energy, which can not only control the reset of the neutral plate 3 but also play a certain buffering effect on the vibration during the processing;

[0035] The circular sleeve is rotatably connected to the limit sleeve 30. A motor 41 is fixedly installed on the surface of the docking arm 40. The output end of the motor 41 is fixedly connected to the rotating disk 43. One end surface of the rotating plate 47 is fixedly connected with a connecting rod in the middle. A clamping seat 42 is connected to the surface of the connecting rod. During the operation of the second bevel gear rod 12, the connecting disk 25 connected to it will drive the convex sleeve 26 to rotate, and the rotating disk 27 at its lower end will rotate together. Whenever the protruding part of the convex sleeve 26 approaches the rotating wheel 38, it will press on it, causing the entire rotating wheel 38 assembly to rotate around the support rod 36. When the toothed disk 39 contacts the locking teeth 28, it will control the rotation of the support shaft 37 with the rotation of the rotating disk 27, and then drive the docking arm 40 to rotate, thereby controlling the clamping seat 42 to rotate by a certain angle, so as to drive the bearing to rotate by the same angle. And as the protruding part of the convex sleeve 26 moves away, the set sleeve 33 will cooperate with the second spring 34 to reset. In order to further adjust the angle of the bearing in three-dimensional space, the user can control the operation of the motor 41. Its output end will drive the rotating disk 43 to rotate. The arc-shaped sleeve 44 on its surface will cooperate with the arc-shaped plate 45 to guide the rotating plate 47, and drive it to rotate 90 degrees each time in cooperation with the arc-shaped groove 48 and the embedded groove 49 on its surface, thereby driving the clamping seat 42 to rotate 90 degrees. Finally, the two cooperate to enable the bearing to perform periodic horizontal and vertical rotations, realizing the dynamic pose adjustment in three-dimensional space during bearing processing, so as to balance the distribution of processing force and the direction of heat input, avoid deformation caused by local thermal expansion, and also offset the elastic deformation of thin-walled parts, improving the processing accuracy of the bearing.

[0036] Working principle of the present invention: In the past, during the processing of bearings, the bearings would be pressed against the surface of the grinding equipment for a long time during the grinding process, which would cause overheating of the local area of ​​the bearing due to long-term friction, and would also cause vibration accumulation and affect the processing accuracy of the bearing. During the operation of this device, after the bearing is fixed, the user can control the driving device at the bottom of the base 1 to drive the anti-slip rod 6 to rotate. First, through the linkage transmission of the transmission bevel gear 9, the first bevel gear rod 10, the driven bevel gear 11 and the second bevel gear rod 12, the accessories connected to the bearing will be controlled to move. At the same time, the eccentric block 8 will also rotate periodically. In this process, when the protruding part of the eccentric block 8 is When the support frame 13 is close to the extension frame 13, the pad wheel on its surface will contact and be pushed, thereby acting in the opposite direction on the surface of the neutral plate 3, and affected by the anti-drop rod 6, the neutral plate 3 will move horizontally, and the first sleeve head 15 accessory connected to the surface of the neutral plate 3 and the side bracket 4, the user can rotate the hand-screw sleeve 16 in advance, so that the threaded rod 17 rotates inside it, and the docking sleeve 20 connected by the threaded sleeve 19 will move with it, and the card cover 22 will be restricted and move in the docking sleeve 20 in cooperation with the slot 21, and as the first spring 24 moves, it will begin to store energy, which can not only control the reset of the neutral plate 3 but also play a role in the vibration during the processing. In order to achieve a certain buffering effect, during the operation of the second bevel gear rod 12, the connecting disk 25 connected thereto will drive the convex sleeve 26 to rotate, and the rotating disk 27 at the lower end thereof will rotate together. Whenever the protruding part of the convex sleeve 26 approaches the rotating wheel 38, it will be pressed, so that the entire rotating wheel 38 accessory rotates around the support rod 36. When the toothed disk 39 contacts the latching tooth 28, it will control the rotation of the support shaft 37 with the rotation of the rotating disk 27, thereby driving the docking arm 40 to rotate, thereby controlling the clamping seat 42 to rotate a certain angle, so as to rotate the linkage bearing by the same angle, and as the protruding part of the convex sleeve 26 moves away, the set 33 will cooperate with the second spring 34 to rotate. Reset, and in order to further adjust the angle of the bearing in three-dimensional space, the user can control the operation of the motor 41, and its output end will drive the rotating disk 43 to rotate. The arc sleeve 44 on its surface will cooperate with the arc plate 45 to guide the rotating plate 47, and cooperate with the arc groove 48 and the embedded groove 49 on its surface to drive it to rotate ninety degrees each time, thereby driving the clamping seat 42 to rotate ninety degrees. Finally, the two cooperate to make the bearing perform periodic horizontal and vertical rotations, and realize dynamic posture adjustment in three-dimensional space during bearing processing, so as to balance the processing force distribution and heat input direction to avoid deformation caused by local thermal expansion, and can also offset the elastic deformation of thin-walled parts and improve the processing accuracy of bearings.
