Description

Technical Field

[0001] The utility model relates to the technical field of surface polishing of shaft parts, in particular to a surface polishing device for shaft parts. Background Art

[0002] In industrial products, shaft parts are used in one or more CNC machine tool parts maintenance operations. Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission parts, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shaft, stepped shaft and special-shaped shaft; or divided into solid shaft, hollow shaft, etc.

[0003] In the processing of shaft parts, some shaft parts have higher processing requirements and need to be ground and polished to make their surfaces smooth and neat. In the early days, when polishing shaft parts, they were manually pushed onto the grinding piece for grinding and polishing. However, this grinding method cannot evenly grind the surface of the shaft parts at one time. When the grinding piece is unstable during slow transmission, it is easy to cause uneven thickness of the polished shaft parts. In addition, the manual pushing and grinding method is highly dangerous. Therefore, we need to propose a surface polishing device for shaft parts. Utility Model Content
