Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically a straightening device for bearing assembly. Background Technology

[0002] After long-term use, bearings may deform due to wear or impact. The inner and outer frames of the bearing, the ball sliding grooves, and the roller holders may deform. When the deformed bearing rotates, the coaxiality between the inner and outer frames will decrease, which will reduce the stability of the equipment. At the same time, the inner and outer frames of the bearing will not wear down as a result, so they need to be corrected.

[0003] The existing bearing straightener (CN107542786A) uses a bearing fixing frame that can be axially fine-tuned to achieve static compression of different positions of the bearing outer frame, thereby achieving fine-tuning of the position between the bearing outer frame and inner frame. This forces deformation of the ball sliding grooves or roller fixing frames of the bearing inner and outer frames, thus calibrating the bearing. However, this device has shortcomings: the existing straightening equipment has poor stability, poor adaptability, poor working efficiency, and is inconvenient to use. Therefore, a bearing assembly straightening device is needed to solve the above problems. Utility Model Content

[0023] The straightening pressure plate 5 is installed by bolts 14 and splicing sockets 15, which are connected to the splicing block 13 in an interlocking bolt configuration. This makes the straightening pressure plate 5 easy to position and disassemble, and improves its adaptability. A rotary motor 7 is installed on the inner wall of the workbench 1, and a mounting block 24 is installed at the output end of the rotary motor 7. The inner wall of the mounting block 24 has a telescopic groove 23, and a second spring 21 is fixedly connected to the inner wall of the telescopic groove 23. A movable support block 22 is fixedly connected to one end of the second spring 21, and a bearing inner ring 6 is fitted on the outer wall of the movable support block 22. The bearing inner ring 6 and the bearing outer ring 8 are elastically supported by the second spring 21, the movable support block 22, and the mounting block 24. The bearing inner ring 6, the bearing outer ring 8, the hydraulic cylinder 4, and the straightening pressure plate 5 are distributed in a double-layer ring position on the workbench 1 and the closed cover plate 3.

[0025] Working principle: When using this bearing assembly straightening device, first connect the device to the power supply. Then, the flipping block 10, servo motor 11, and flipping seat 12 drive the closing cover 3 to flip open. Next, the bearing inner ring 6 and bearing outer ring 8 are supported and installed by the second spring 21, movable support block 22, and mounting insert block 24. Then, the first spring 18 and limit slider 19 drive the limit roller 16 and limit clamp 17 to limit and clamp the outer wall of the bearing outer ring 8. Then, the closing cover 3 is closed. Then, the rotary motor 7 drives the bearing inner ring 6 and bearing outer ring 8 to rotate. Then, the hydraulic cylinder 4 drives the rotation of the bearing inner ring 6 and bearing outer ring 8. The moving straightening pressure plate 5 presses down and rolls and squeezes the inner ring 6 and outer ring 8 of the bearing through the rotating guide roller 9 to straighten them. The limit roller shaft 16 and the limit clamp 17 are used for elastic adaptation and adjustment. After the straightening is completed, the closed cover plate 3 can be quickly removed. When it is necessary to adapt to the inner ring 6 and outer ring 8 of the bearing of different sizes, they can be elastically adapted and installed through the second spring 21 and the movable support block 22. The straightening pressure plate 5 and the rotating guide roller 9 can be adapted and replaced through the splicing plug 13, the fixing bolt 14 and the splicing socket 15. This is the usage process of the straightening device for bearing assembly.
