Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to an end face bearing polishing machine. Background Art

[0002] Bearings are an indispensable and important component in various mechanical devices, which directly affects the operating performance and life of the equipment. The bearing end face polishing machine is a key device for polishing bearings. It is generally composed of a motor, a grinding wheel mechanism, a fixture, etc. After the bearing is installed in the fixture, the motor drives the grinding wheel to rotate at high speed, and the grinding wheel contacts the bearing end face. Through the action of friction, the bearing end face is polished.

[0003] Currently, most of the bearing end face polishing machines on the market are automated, and some even integrate inner ring polishing and outer ring polishing into one. However, automated bearing end face polishing machines will inevitably produce defective products during production. Some of these defective products have cutting allowances and can be remedied. In this case, a manual bearing polishing machine is needed.

[0004] The main problems of defective bearing end faces are insufficient roughness, insufficient verticality, insufficient flatness, etc. Among them, insufficient verticality and insufficient flatness are very demanding on the operator's skills when corrected with a polishing machine, because the manual end face polishing machine is for flat polishing. If the bearing end face is tilted, the operator needs to rely on hand feel and different pressures to correct the tilted bearing end face, which makes the operation difficult. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an end face bearing polishing machine, which solves the technical problem that the existing end face bearing polishing machine is difficult to operate when remedying defective products.

[0007] The polishing disc is evenly distributed with dividing grooves in the circumferential direction, and the dividing grooves divide the polishing disc into a fan-shaped structure evenly distributed in the circumferential direction. The bottom center of the polishing disc is connected to a polishing drive device through a transmission. A full-circular polishing sandpaper is provided on the upper side of the polishing disc. A positioning mechanism is also provided on the upper side of the center of the polishing disc.

[0008] The technical principle of the utility model is as follows: dividing grooves are provided so that the polishing disc becomes a fan-shaped structure, and then when passing through the position of the clamping mechanism, it is pressed by the clamping mechanism to bend upward, giving greater pressure to the bearing polished on the upper side. At this time, the side that needs to remove the excess is polished here, without the need for manual tilting pressure to one side.

[0009] Compared with the prior art, the utility model has the following beneficial effects: by using a clamping mechanism in conjunction with a polishing disc with evenly distributed dividing grooves, the utility model solves the technical problem of the existing end face bearing polishing machine being difficult to operate when remedying defective products.

[0010] Furthermore, the polishing drive device and the polishing disc are provided with a common support frame, and the clamping mechanism is also fixed on the support frame.

[0011] Furthermore, the clamping mechanism includes an elastic pressure rod and a clamping pulley installed at one end of the elastic pressure rod, the other end of the elastic pressure rod is bolted on the support frame, and the clamping pulley is clamped on one side of the polishing disc.

[0012] In actual use, the position of the clamping pulley can be adjusted according to the position of the bearing end face to ensure that the bearing end face and the clamping pulley are in corresponding positions.

[0013] Furthermore, the positioning mechanism includes a positioning ring and V-shaped elastic strips evenly distributed circumferentially on the fixed ring. The V-shaped elastic strips are inverted, one end of the V-shaped elastic strips is fixed on the fixed ring, and the other end of the V-shaped elastic strips extends beyond the outer edge of the fixed ring and is located on the upper side of the polishing disk.

[0014] Furthermore, the positioning mechanism also includes a pressing block, a ring-shaped groove is provided at the bottom of the pressing block, and a handle is provided on the upper side of the pressing block.
