Small polisher and polishing method thereof

Abstract

The invention discloses a small polisher and a polishing method thereof, and belongs to the technical field of cutting machining. The small polisher comprises a polishing head assembly and a polishing braking assembly, wherein the polishing head assembly comprises a pneumatic motor and a polishing head detachably fixed to a rotary shaft of the motor; the polishing braking assembly comprises a housing as well as a drive air channel, braking air channels and running air channels which are arranged in the housing and mutually independent; the housing is a cylinder with an open end and a closed end; the pneumatic motor enters the cylinder from the open end and is fixed to the cylinder; the drive air channel is an axial air inlet hole; the braking air channels are a plurality of radial air holes; and the running air channels are a plurality of inclined air holes. According to the small polisher and the polishing method thereof which are disclosed by the invention, drive power, braking power and movement power are provided through the three mutually independent air channels respectively to realize polishing operation in an inner hole; a long tool bar in the prior art is cancelled, the rigidity of the cutting point of the small polisher is greatly improved, and the machining quality is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of cutting processing, and in particular relates to a small grinder capable of grinding an inner hole of any length and a grinding method thereof. Background technique [0002] In the cutting process, the inner wall processing of long tubular parts is a problem that has plagued all robots for a long time. The diameter cannot be increased without limit, so the rigidity of the cutting point at the far end becomes weaker, and the deformation amount increases with the increase of the length under the action of cutting force, which eventually leads to an irregular tapered inner wall of the processed tube , affecting the straightness and roughness of the inner hole. [0003] In view of the above problems, if a new structure of grinding equipment can be proposed and the processing method can be changed so that the tool length is constant and does not need to be lengthened with the increase of the inner hole length...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to provide a small grinder and its grinding method, the tool length is constant, without lengthening, grinding can be carried out in the inner hole of any length, to solve the existing technology due to the length of the tool bar The problem of low processing quality caused by the lengthening of the part length
