Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub bearings, in particular to a fully automatic flexible automobile wheel hub bearing circular grinding mechanism. Background Art

[0002] Wheel hub bearings are components used on automobile axles to bear weight and provide precise guidance for the rotation of the wheel hub. They bear both axial and radial loads and are an important part of the vehicle's load-bearing and rotation. During production, the wheel hub bearings need to be polished by a grinding mechanism to reduce the roughness of the ring surface and avoid damage due to excessive friction during use.

[0003] A grinding auxiliary device for automobile wheel hub bearing production disclosed in the Chinese utility model patent application disclosure CN219987051U, although the wheel hub bearing is placed on the corresponding support ring, the first electric push rod can make the roller press tightly on the wheel hub bearing to fix the wheel hub bearing, the third electric push rod adjusts the position of the first grinding block and the second grinding block so that the first grinding block and the second grinding block are aligned with the wheel hub bearing, the second electric push rod controls the first grinding block and the second grinding block to move downward and contact with the inner and outer walls of the wheel hub bearing, the motor drives the rotating disk to rotate, the wheel hub bearing rotates relative to the first grinding block and the second grinding block, and the inner and outer sides of the wheel hub bearing are polished at the same time. Grinding is convenient and improves the use effect. However, the equipment cannot rinse and cool the grinding disc during grinding, nor can it cool the bearing being ground and rinse the bearing after grinding, so that there is no grinding residue inside the bearing, and the sprayed water cannot be recycled, which wastes resources, reduces the service life of the grinding disc, affects work efficiency and equipment usability, and fails to improve the quality of the bearing. It is also impossible to detect and observe the polished bearing immediately after grinding to determine whether the bearing grinding is qualified, and it is impossible to perform grinding inspection on multiple bearings, which reduces work efficiency and wastes manpower and material resources. Therefore, we propose a new device to solve the above problems. Utility Model Content

The water in the water tank is pumped out through the water pump and sprayed out through the spray gun to cool and rinse the bearing. The sprayed water passes through the leak plate and enters the leak box, which avoids the bearing overheating due to insufficient water during grinding, causing damage to the bearing and the grinding disc. After the bearing is ground, there is no way to rinse it, which reduces work efficiency and affects the usability of the equipment, thereby increasing the life and utilization rate of the equipment, increasing the quality of the bearing, increasing the service life of the grinding disc, avoiding the waste of water resources, and increasing work efficiency.

Multiple bearings can be placed, and the air pump is used to spray air from the hose and the nozzle to blow and rotate the bearing. The camera is used to observe whether the bearing is polished smooth and the polished roundness is qualified during the rotation process. After the inspection is completed, the bearing is adsorbed by the electromagnet suction cup and then placed in the collection device. This avoids the inability to immediately detect and observe whether the bearing has been polished to a qualified standard after the grinding is completed. The bearing is taken out and then tested and observed, which reduces work efficiency, increases manpower and material resources, and increases the workload of the staff. Therefore, direct testing after grinding can greatly improve work efficiency and save manpower and material resources. Camera detection is safer and faster, and multiple bearings can be detected at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
