Description

Technical Field

[0001] The invention relates to the technical field of bearing grinding, in particular to an automobile bearing grinding device. Background Art

[0002] The main function of the bearing is to bear weight and provide precise guidance for the rotation of the wheel hub. It bears both axial load and radial load, and is a very important component. Automobile bearings are a large part of the bearing industry, including wheel hub bearings, air conditioning fan bearings, pulley bearings, etc., which are divided into high-speed automobile bearings and low-speed automobile bearings. There are basically two ways to grind bearings, one is to grind by rotating the bearing, and the other is to grind by rotating the turntable. When grinding the bearing, it is generally done by grinding alone, which has low work efficiency.

[0003] To this end, a Chinese patent with publication number "CN208117468U" announced "an automobile bearing grinding device", whose main structure includes a placement plate, a support frame is fixedly installed on the upper end of the placement plate, a motor is arranged on the right side of the placement plate, a rotating rod is fixedly installed on the output end of the motor, and the rotating rod is inserted into the inner cavity of the support frame, and a limit ring is fixedly installed on one end of the rotating rod. The automobile bearing grinding device, through the structural design of the placement plate, support frame, motor, rotating rod, limit ring, moving ring, connecting rod, slide groove, slider, jack, connecting groove, reset spring, insertion rod, support column and U-shaped grinding disc, allows the bearing to be inserted into the rotating rod, and then the moving ring squeezes the limit ring to fix the bearing, so that multiple bearings can be inserted into the rotating rod for grinding at the same time, which solves the problem that when the bearing is rotating and grinding, a single grinding is generally used, which has low work efficiency.

[0004] However, during the actual grinding of the bearing, since the bearing is inserted with the shaft hole portion inserted into the rod body of the movable rod, the bearing is prone to rotation after being subjected to the grinding force, resulting in low grinding efficiency and poor control over the bearing. In addition, during the grinding process, the bearing cannot effectively control the pressure between the grinding surface and the grinding column, which also results in poor grinding control.
