Description

Technical Field

[0001] The utility model relates to the field of wear-resistant ball polishing, in particular to a wear-resistant ball polishing device. Background Art

[0002] With the continuous development of the machinery industry, the demand for metal balls is increasing. The surface defects of metal balls will affect the performance of various machines. Therefore, improving the surface defects of metal balls has received more and more attention from the industry. The patent with application number CN202222489029.3 proposes a steel ball grinding and dust removal device, which clamps a sphere through two hemispherical covers of a return pipe, and then grinds the sphere through the grinding layer of the hemispherical cover; however, the hemispherical cover exerts force on the sphere, causing the sphere to rotate around the axis of the return pipe, and there is no other force to drive the sphere to rotate in a direction perpendicular to the axis of the return pipe, resulting in an annular line area on the sphere that is not polished due to the contact surface of the two hemispherical covers, that is, there will be an annular line on the surface of the sphere, thereby affecting the smoothness and appearance of the ball head; therefore, a wear-resistant ball polishing device is proposed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model proposes a wear-resistant ball polishing device, which clamps the ball through a polishing block and friction-polishes the ball through two counter-rotating polishing blocks. During the polishing process, a friction column is used to change the position of the ball, thereby completing comprehensive polishing of the ball.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A spherical groove is arranged on the grinding block; the circular angle corresponding to the arc of the cross section of the spherical groove is less than 180 degrees; so that after the two spherical grooves move, they do not form a complete circle, and when they move to the position corresponding to the complete circle of the arc of the cross section, there will be an annular space in the middle; the main material of the grinding block or its material in the spherical groove is the same as the material of the polishing sheet;

[0011] When in use, place the sphere between the grinding blocks; then drive the movable seat to move so that the two grinding blocks clamp the sphere in the spherical groove; because the circular angle corresponding to the arc of the cross section of the spherical groove is less than 180 degrees; the grinding block cannot completely cover the sphere, but exposes the middle position of the sphere; then drive the movable block to move downward so that the friction column contacts the sphere; then drive the two motors one to rotate in opposite directions, and motor one grinds the surface of the sphere through the grinding block. During the grinding, motor two moves up and down and motor two drives the friction column to rotate. The friction column will drive the sphere to rotate, changing the contact surface between the sphere and the grinding block, so that the sphere is fully polished, and there will be no annular coil-shaped area on the surface of the sphere that has not been polished.
