[0002] With the continuous development of the machinery industry, bearings are used more and more widely in various mechanical equipment. As an important component of the bearing, the surface quality of the bearing cage directly affects the performance and service life of the bearing. In the production process of the bearing cage, surface deburring and grinding are essential processes.

[0003] The bearing retainer needs to be punched with side holes. However, local edge bending, burrs and debris may occur during the punching process. If these defects are not eliminated in time, the subsequent processing procedures will be affected. In the prior art, when processing the bearing retainer, the grinding operation of the burrs on the surface of the bearing retainer can only be achieved by a grinding wheel. Moreover, during the grinding process, it is difficult to clean the debris attached to the surface of the bearing retainer. The deburring, cleaning and rust removal processes of the bearing retainer are mostly achieved by a single-function device, which has low production efficiency and rarely considers the shaping requirements of the local bending of the bearing retainer, which easily causes the outer surface of the bearing retainer to be deformed by grinding. Therefore, a bearing retainer surface processing device is needed to solve the above problems. Summary of the invention

[0014] The present invention has at least the following beneficial effects: 1. By setting up an upper grasping mechanism and a lower grasping mechanism, the grinding operation on the inner and outer sides of the bearing retainer is realized. Compared with the traditional structure, the device performs magnetic suction operation on the top of the bearing retainer through an electromagnetic suction cup, and the piston rod of the first hydraulic telescopic push rod moves to push the upper grinding accessory. The upper grinding accessory contracts inward so that its inner surface contacts the outer side of the bearing retainer, and the lower movable splint expands outward so that its outer surface contacts the inner side of the bearing retainer. The lower movable splint squeezes it, thereby adapting the inner and outer sides of the bearing retainer to the contact positioning, thereby ensuring the grinding flatness of the bearing retainer surface.

[0015] 2. By setting the injection hole, the upper grinding accessory and the lower grinding accessory, the grinding effect of the surface of the bearing retainer can be improved. When the device needs to grind the outer side of the bearing retainer, the bottom clamp and the lower movable clamp can be kept from rotating. The upper motor is started to drive the first rotating shaft to rotate, so that the first rotating shaft drives the top clamp to rotate, and the top clamp drives the upper movable clamp to rotate. The upper grinding disc on the inner side of the upper movable clamp rotates and grinds the outer surface of the bearing retainer. When it is necessary to grind the inner side of the bearing retainer, the upper grinding accessory does not rotate, and the lower motor is started to make the lower motor shaft end drive the second rotating shaft to rotate. The second rotating shaft can drive the bottom clamp and the lower movable clamp to rotate, so that the lower grinding disc on the outer side of the lower movable clamp grinds the inner side of the bearing retainer. At the same time, grinding aids can be added to the inside through the injection hole to further improve the grinding effect of the bearing retainer of the processing table group.

[0016] 3. The surface of the bearing cage can be cleaned by setting a processing table group and an injection hole. When the bearing cage needs to be cleaned, the electromagnetic suction cup magnetically docks the bearing cage, and the upper movable splint extends outward under the tension of the first hydraulic telescopic push rod. At the same time, the piston end of the second hydraulic telescopic push rod retracts to pull the lower movable splint, causing the lower movable splint to shrink inward, thereby leaving a gap between the bottom splints, which is convenient for flushing the surface of the bearing cage through the gaps and crevices. At the same time, the cleaning agent is poured through the injection hole to improve the cleaning effect of the bearing cage. An inclined lower groove is opened on the surface of the table, and the cleaning liquid is guided by the cooperation of the lower groove and the guide port, which is convenient for collecting the cleaning liquid.

The upper grinding plate 371 is continuously rotated and retracted to facilitate the upper grinding plate 372 to limit and clamp the bearing retainer. The upper grinding plate 372 is attached to the surface of the bearing retainer.

[0033] After the lower movable clamping plate 44 rotates, the lower movable clamping plate 44 retracts to form a complete gap between the bottom clamping plate 43 and the top clamping plate 33, which is convenient for subsequent staff to clean the surface of the bearing retainer. At the same time, the design of the injection hole 34 on the surface of the top clamping plate 33 is convenient for the staff to inject cleaning liquid into the gap through the injection hole 34.

[0034] Working principle: According to the attached Figure 1 With attached Figure 2As shown, during use, the bearing holder can be placed on the top of the bottom clamping plate 43. At this time, the piston rod end of the cylinder 23 extends to drive the beam plate 24 to move, and the beam plate 24 can drive the slider 25 to move downward in the guide groove of the side frame 21. During the movement of the beam plate 24, the upper grabbing mechanism 3 can be moved downward as a whole. After the operation is completed, the piston rod end of the first hydraulic telescopic push rod 36 extends to push the upper movable clamping plate 371, so that the upper movable clamping plate 371 rotates and retracts to clamp the support holder. At the same time, the upper motor 31 is started, and the shaft end of the upper motor 31 can drive the first rotating shaft 32 to rotate, so that the first rotating shaft 32 drives the top clamping plate 33 to rotate, and the top clamping plate 33 can drive the bearing holder to rub on the surface of the lower grinding plate 451, and the lower grinding plate 451 can grind the inner side of the bearing holder. Secondly, according to the attached Figure 7 With attached Figure 8 As shown, by extending the piston rod end of the second hydraulic telescopic push rod 46 to push the lower movable clamping plate 44, the lower movable clamping plate 44 pushes the lower grinding plate 451 to contact the inner side of the bearing retainer for fixing, at this time, the upper movable clamping plate 371 is adjusted during the extension of the first hydraulic telescopic push rod 36, so that the upper grinding plate 372 is as close to the outer side of the bearing retainer as possible, and by starting the upper motor 31, the shaft end of the upper motor 31 drives the top clamping plate 33 to rotate, and the top clamping plate 33 can cooperate with the upper movable clamping plate 371, and then drive the upper grinding plate 372 to grind the outer side of the bearing retainer; Finally, after the bearing retainer is polished, the grinding aid and the rust remover can be injected through the injection hole 34 to improve the polishing effect of the bearing retainer. After the bearing retainer is polished, the bearing retainer can be magnetically docked through the electromagnetic suction cup 35. The upper movable clamp 371 is driven to rotate by starting the first hydraulic telescopic push rod 36, and the lower movable clamp 44 is retracted by retracting the piston rod end of the second hydraulic telescopic push rod 46, thereby forming a cavity between the bottom clamp 43 and the top clamp 33. At this time, the surface of the bearing retainer can be easily flushed. During the flushing, the detergent can also be injected through the injection hole 34 to improve the cleaning effect. The flushing water during cleaning is guided by the inclined groove at the top of the table 11, and the flushing water is collected and concentrated through the guide port 13.
