External hand-held electric polishing tool with air sac polishing head

Abstract

The invention provides a built-out hand-held electric polishing tool with a gasbag polishing head, comprising a shell, a driving motor, a polishing head with the gasbag, a gas delivering shaft; the polishing head with the gasbag comprises a polishing head framework and a gasbag cover which is hermetically arranged at one end of the polishing head framework which has hollow structure; the gas delivering shaft is a half hollow shaft; the hollow end of the gas delivering shaft is connected with the other end of the polishing head framework; the gas delivering shaft is provided with a shaft hole which is communicated with the hollow end of the gas delivering shaft which is externally sheathed with a gas conducting sleeve; the gas conducting sleeve is provided with a through hole which is communicated with an air pipe which is communicated with a built-out air source; two sides between the gas conducting sleeve and the gas delivering shaft are provided with two sealing parts; an air chamber is arranged between the two sealing parts; the through hole is communicated with the air chamber which is communicated with the shaft hole of the gas delivering shaft. The invention has the advantages of small processing area, good coincident characteristic, high dedusting efficiency of the material, and stable polishing area.

Description

technical field [0001] The invention relates to a hand-held electric polishing tool. Background technique [0002] In recent years, the development of the mold manufacturing industry has become increasingly rapid, and it has become more and more extensive. Such as automobiles, aviation, ships, toys, electronic products, household appliances, etc., are almost omnipresent. After the mold is manufactured, there are certain errors, and the surface of the mold is required to be smooth, so it needs to be polished in the later stage to meet this requirement. Not all of the current molds are large, so they do not all need to be polished by a large polishing machine. Some small molds can be polished by a small hand-held electric polishing tool, and some curved surfaces of large molds are often difficult to polish. Polishing is done on large polishers, which requires the use of small hand-held power polishing tools. The disadvantages of the existing hand-held electric polishing too...
