Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to a polishing mechanism and an axial continuous polishing device for valve housings with unequal outer diameters. Background Technology

[0002] During device processing, the device surface needs to be polished or ground. Polishing and grinding are currently mainly done using polishing machines. Polishing machines achieve polishing and grinding of the device surface by the relative movement of the polishing belt on the polishing structure and the device to be polished under certain pressure.

[0003] Because the polishing belt is relatively wide, when an object is moved up and down perpendicular to the belt for polishing, the belt makes full contact with the object in the entire width direction. This full contact method results in a short service life for the belt. Therefore, we propose a polishing mechanism to solve the above problems. Utility Model Content
