Polishing head and automatic polishing machine

Abstract

The invention discloses a polishing head and an automatic polishing machine. The polishing head comprises a rotating shaft comprising a rotating center line and a rotating surface perpendicular to the rotating center line and an eccentric bearing having a central axis; the eccentric bearing comprises a first end connected to the rotating surface and a second end away from the rotating surface; the central axis is staggered with the rotating center line; the polishing head further comprises a fixing pad connected with the second end of the eccentric bearing and a polishing piece located on the surface of the side, away from the eccentric bearing, of the fixing pad. The polishing head can automatically polish the surface of a workpiece by controlling rotation of the rotating shaft, and due to the fact that the rotating center line of the rotating shaft and the central axis of the eccentric bearing are staggered, in the rotating process of the eccentric bearing, the polishing piece connected with the eccentric bearing can generate tiny translational motion, then translational polishing is performed on the surface of the workpiece, the polishing mode using the tiny translational motion is novel, and damage to the surface of the workpiece can be reduced.

Description

technical field [0001] The invention relates to the technical field of workpiece surface processing, in particular to a polishing head and an automatic polishing machine. Background technique [0002] Due to the complexity and diversity of mold workpieces and the characteristics of non-standard parts processed in a single piece, the mold polishing process in the industry has always been purely manual polishing. Manual polishing takes up a lot of manpower and consumes employees' physical energy for a long time. With the progress of the times, With the rapid development of automated production technology, the career of polishing workers is gradually not being yearned for by young people. In recent years, there have been difficulties in recruiting workers, and the lack of young people’s inheritance of polishing technology. According to the development trend, there will be a serious shortage of polishing workers in the future in 2031. The cost of mold polishing The inevitable tr...

[0002] Due to the complexity and diversity of mold workpieces and the characteristics of non-standard parts processed in one piece, the mold polishing process in the industry has always been purely manual polishing. Manual polishing takes up a lot of manpower and consumes employees' physical energy for a long time. With the progress of the times, With the rapid development of automated production technology, the career of polishing workers is gradually not being yearned for by young people. In recent years, it has become difficult to recruit workers, and the polishing technology lacks the trend of young people’s inheritance. According to the development trend, there will be a serious shortage of polishing workers in the future in 2031. The cost of mold polishing rising inevitable trend
