Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing, and in particular relates to a grinding device for processing a bearing outer ring. Background Art

[0002] Bearings are a crucial component in modern mechanical equipment. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. Bearings typically consist of annular inner and outer rings. During manufacturing, the outer ring inevitably develops burrs, which can adversely affect subsequent use and installation. Therefore, workers typically use a steel brush to polish these teeth to remove the burrs. However, this process is inefficient and labor-intensive.

[0003] In the prior art, patent number CN211332477U is a mechanism for grinding the inner and outer rings of bearings, including an inner ring grinding block, a first rotating cylinder hinged inside the inner ring grinding block, two inner ring abutment plates opposite each other and capable of approaching or moving away from the center line of the first rotating cylinder being movably connected to the first rotating cylinder, an outer ring grinding module that can move toward or away from the inner ring grinding block in the horizontal direction is movably provided on one side of the inner ring grinding block, two outer ring abutment plates corresponding one to one with the inner ring abutment plates are movably connected to the outer ring grinding module, the inner ring grinding block is also provided with a machine base, and a driving component for grinding the bearing is provided in the machine base.

[0004] In the above device, the outer surface of the bearing ring is clamped by two outer ring support plates, and the inner surface of the bearing outer ring is clamped by two inner ring support plates, and then the inner and outer surfaces of the bearing outer ring are polished. However, during the polishing process, the fixed state of the bearing outer ring will become unstable due to the rotation of the outer ring support plates and the inner ring support plates, thereby affecting the polishing effect. In addition, the polishing method in the above device cannot be carried out continuously, and the processing efficiency is slow. Utility Model Content

The connecting rod passes through the side of the fixed seat and an arc-shaped push plate is fixedly provided on its outer end surface. The arc-shaped push plate is slidably provided in the fixed seat.

[0011] Optionally, a grinding block is fixedly provided on the side of the support plate 2, and the grinding block corresponds to the position of the arc-shaped push plate and is located on the same horizontal line. An arc-shaped grinding groove is provided on one side of the grinding block, which corresponds to the size of the outer surface of the outer ring of the bearing, and an arc-shaped grinding layer is fixedly provided in the arc-shaped grinding groove of the grinding block.

[0014] In the present invention, the outer ring of the bearing pushed into the fixed seat is pushed by the telescopic cylinder until it contacts the arc-shaped polishing layer. At this time, the outer ring of the bearing can be fixed and clamped, and then the electric telescopic rod 2 is started to make the rotating block close to the position of the through hole, and then the slider 2 will contact the piston rod of the electric telescopic rod 1, and then the electric telescopic rod 1 drives the piston rod to squeeze the slider 2, so that the slider 2 squeezes the slider 1 through the inclined surface, so that the arc-shaped polishing plate outside the slider 1 contacts the inner wall of the outer ring of the bearing. At this time, The motor drives the rotating block to grind the inner wall of the bearing outer ring. After grinding, the inner wall of the bearing outer ring is fixed by the arc-shaped grinding plate, and then the clamping force on the outer surface of the bearing outer ring is loosened. Then the outer surface of the bearing outer ring can be grinded. This grinding method can realize continuous grinding of the bearing ring through the continuous pushing of the telescopic cylinder, which greatly improves the grinding efficiency. In addition, the inner and outer surfaces of the bearing outer ring can be stably fixed and clamped during the grinding time, which is beneficial to improving the grinding effect of the bearing outer ring.
