Main and auxiliary combined type air bag polishing tool

Abstract

The invention relates to a main and auxiliary combined type air bag polishing tool which comprises an air bag, an air conveying shaft and an air pump, wherein the air bag comprises a retainer and an outer air bag cover, and the outer air bag cover is arranged at one end of the retainer; a hollow section of the air conveying shaft is connected with the other end of the retainer, and a solid end of the air conveying shaft is connected with a rotating and driving mechanism; the air conveying shaft is sleeved in an air conducting sleeve, a through hole is arranged on the air conducting sleeve and communicated with an air outlet of the air pump, and the air conducting sleeve is in sealing connection with the air conveying shaft; the air bag is connected with the air conveying shaft through a turntable and filled with a plurality of constant pressure sub air bags and a plurality of controllable pressure sub air bags; and the turntable is provided with a main vent hole and an auxiliary vent hole and connected with an adjustment mechanism. In the invention, an auxiliary air bag control link is added, which improves the controllability to the internal structure of the air bag; the inner combination property of the air bag is good and meets the requirement of the variability; and the structure is simple and convenient to realize.

Description

technical field [0001] The invention relates to a polishing tool in the field of precision machining, in particular to a polishing tool that is combined with a robot-assisted airbag polishing technology to improve the airbag on the basis of improving the stress field effect in the actual polishing work area, the stability of the precession track, and the polishing efficiency. The main and auxiliary compound airbag polishing tool with the distribution of force and prolonging the service life of the polishing device. Background technique [0002] In order to obtain a smooth, uniform and high-quality surface so that polished parts can be better used in industrial occasions, polishing is an essential process. Under the premise of ensuring the surface accuracy and surface quality of the polished parts, the implementation of the polishing process can effectively improve the corrosion resistance and wear resistance of the surface and prolong its service life. [0003] In the proce...
