The technical solution of the utility model is as follows:

a bearing ring flexible polishing device comprises a motor, a polishing disc and a bearing ring, wherein a top plate and a platen are fixed on an upright post, the motor is fixed on the top plate, the polishing disc is fixed on a rotating shaft of the motor, a polishing recess is formed in the upper end surface of a polishing die, a plurality of inserting posts are formed in the lower end surface of the polishing die, the bearing ring is placed in the polishing recess, and the inner diameter of the polishing recess is 0.2-0.6 mm larger than the outer diameter of the bearing ring;

a plurality of guide cylinders are formed on the lifting disc, each insertion column is inserted into one guide cylinder, a spring is inserted into the guide cylinders, the lower end of the spring is welded and fixed on the lifting disc, and the upper end of the spring is pressed on the lower end face of the polishing die;

the cylinder is fixed on the bedplate, and the piston rod of cylinder is together fixed with the lifting disk, and there are two cylinders.

A step surface is formed on a rotating shaft of the motor, the polishing disc is clamped between the compression nut and the step surface, and the compression nut is screwed on the rotating shaft of the motor.

The at least three inserting columns are distributed on the grinding die in an annular array mode by taking the circle center of the grinding die as the center.

The lower end of the lifting disc is formed with a guide sleeve, and the upper end of a piston rod of the cylinder is inserted in the guide sleeve and fixed with the guide sleeve through a screw.

The axial lead of the rotating shaft of the motor and the axial lead of the lifting disc are positioned on the same straight line.

The beneficial effects of the utility model reside in that:

the flexible polishing device can flexibly polish the end face of the bearing ring, is suitable for polishing the end faces of the bearing rings with various sizes, and can apply different pressures to polish the end faces of the bearing rings.

In the figure: 1. a motor; 2. grinding disc; 3. a bearing ring; 4. a column; 5. a top plate; 6. a platen; 7. polishing the mold; 8. a lifting plate; 9. a spring; 10. a cylinder; 11. and (5) pressing the nut.

Detailed Description

Example (b): as shown in fig. 1 to 3, a bearing ring flexible polishing device comprises a motor 1, a polishing disc 2 and a bearing ring 3, wherein a top plate 5 and a platen 6 are fixed on an upright post 4, the motor 1 is fixed on the top plate 5, the polishing disc 2 is fixed on a rotating shaft of the motor 1, a polishing recess 71 is formed on the upper end surface of a polishing mold 7, a plurality of insert columns 72 are formed on the lower end surface of the polishing mold 7, the bearing ring 3 is placed in the polishing recess 71, and the inner diameter of the polishing recess 71 is 0.2 to 0.6mm larger than the outer diameter of the bearing ring 3;

a plurality of guide cylinders 81 are formed on the lifting disc 8, each inserting column 72 is inserted in one guide cylinder 81, the spring 9 is inserted in the guide cylinders 81, the lower end of the spring 9 is welded and fixed on the lifting disc 8, and the upper end of the spring 9 is pressed on the lower end surface of the grinding die 7;

the cylinder 10 is fixed on the bedplate 6, the piston rod of the cylinder 10 is fixed with the lifting disc 8, and the number of the cylinders 10 is two.

Step surfaces 1a are formed on a rotating shaft of the motor 1, the polishing disc 2 is clamped between the compression nut 11 and the step surfaces 1a, and the compression nut is screwed on the rotating shaft of the motor 1.

The at least three insert posts 72 are distributed on the grinding mold 7 in an annular array with the center of the circle of the grinding mold 7 as the center.
