Abstract

The invention relates to a polishing device of a high-speed air flotation spindle airbag, and relates to airbag polishing devices. The polishing device is provided with an upper end cover, a lower endcover, an air flotation bearing mechanism, an air drive mechanism, an airbag pressure control mechanism and an airbag polishing head assembly. A shell of a cavity is formed by the upper end cover andthe lower end cover and is provided with a drive part air inlet hole, a drive part air outlet hole, four threaded holes, an air flotation bearing air inlet hole, a thrust bearing air outlet hole, a radial bearing air outlet hole, an air runner, a connecting threaded hole and the cavity. The air flotation bearing mechanism is provided with a radial bearing assembly and a thrust bearing assembly. The air drive mechanism is provided with a drive part and a fixed part and is mounted on a rotating shaft. The airbag pressure control mechanism is used for controlling the inner pressure of an airbaghead. The airbag pressure control mechanism is provided with an air pipe, a rapid joint, a sealing bearing and a locking nut. The airbag polishing head assembly is provided with a handle, a locking nut, two fixed parts, a 304 steel liner bottom part and a rubber part.

Description

technical field [0001] The invention relates to an airbag polishing device, in particular to a high-speed air-floating spindle airbag polishing device. Background technique [0002] High-speed machining technology integrates high cutting speed, high feed speed and high machining accuracy. At present, the spindles that realize high-speed precision machining on the market mainly include: high-speed electric spindles, high-speed electromagnetic spindles, etc. These high-speed spindles have relatively good processing performance. However, it also has problems such as expensive manufacturing and high maintenance costs in the later period, which has certain limitations. [0003] Due to the flexible polishing surface of the airbag head, the airbag polishing technology can adjust the air pressure according to the curvature and roughness requirements of the polished surface so that the polishing tool can maintain a good fit while having a large contact area with the workpiece surface...
