Description

Technical Field

[0001] The present invention relates to the technical field of surface polishing, and particularly relates to a surface polishing device for bearing steel. Background Art

[0002] Bearing steel is a steel raw material used in the prior art for producing steel parts such as ball bearings, roller bearings, and bearing rings. Bearing steel has high-quality and uniform hardness and wear resistance. During the production and forming process of bearing steel, extremely high requirements are imposed on the uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides. It is one of the steel types with the most stringent production requirements among all steels. After the bearing steel is cast, the outer surface of the bearing steel is cylindrical at this time. However, during the forming process of the bearing steel, there are often some burrs and other defective parts on the surface of the bearing steel. In order to facilitate subsequent processing operations on the bearing steel, during the processing of the bearing steel, people often use a sand belt grinding device to grind the surface of the bearing steel.

[0003] However, when actually using a sand belt grinding device to grind the bearing steel, in order to ensure that the sand belt grinding device has sufficient polishing effect on the bearing steel, usually the moving path of the bearing steel is perpendicular to the circular moving path of the grinding sand belt of the sand belt grinding device. Since the unfolded area of the bearing steel is small, and in order to enable the grinding sand belt to perform stable circular movement, the driving and unfolding area of the grinding sand belt is large. This leads to the problem that the relatively long grinding area on the sand belt grinding device is difficult to make full use of when polishing the surface of the bearing steel with the sand belt grinding device. Summary of the Invention

[0004] The present invention provides a surface polishing device for bearing steel, which solves the problem that when using a sand belt grinding device in the related art to polish the surface of bearing steel, the relatively long grinding area on the sand belt grinding device is difficult to make full use of.

[0043] Working principle of the bearing steel surface polishing device:

[0044] First, a plurality of bearing steels are respectively placed on the conveying frame 22 on one side close to the mounting frame 26, so that the bearing steels are placed between the semi-circular grooves of the corresponding plurality of conveying support plates 23.

[0045] Adjust the inclination angle of the abrasive belt polishing device 2 in advance according to the unfolded areas of multiple bearing steels. Start the second drive motor 28 to drive the transmission lead screw 27 to rotate, so that the moving seat 10 moves within the installation base frame 1, adjust the positions of the components installed on the moving seat 10, and move the meshing insertion plate 13 into the corresponding meshing seat 8.
