Handheld grinding device suitable for one-key cleaning of multi-size grinding wheels

Abstract

The invention relates to the related field of grinding equipment, and discloses a handheld grinding device suitable for multi-size grinding wheel one-key cleaning. The handheld grinding device comprises a main body box, wherein a cleaning box cavity with a downward opening is formed in the main body box, a cam cavity is communicated with the tail end of the left side of the upper end wall of the cleaning box cavity, and an auxiliary friction wheel cavity located on the right side of the cam cavity is formed in the upper side of the cleaning box cavity. According to the device, integrated control over speed regulation and cleaning is achieved through a speed regulation button and a cleaning button in the speed regulation button, that is, when the grinding wheel needs to be cleaned, the cleaning button and the speed regulation button can be pressed down at the same time, and therefore the rotating speed of the grinding wheel is automatically decreased; and meanwhile, in cooperation witha brush capable of reciprocating on the outer edge surface of the grinding wheel, the grinding wheel is cleaned, by rotating a size knob, the position of the brush can be adjusted at will according tothe diameter of the grinding wheel, universality is high, the grinding mode can be switched back immediately only by loosening the speed regulation button, convenience is achieved, and the workpiecegrinding efficiency is improved.

Description

technical field [0001] The invention relates to the related field of grinding equipment, in particular to a hand-held grinding device suitable for one-key cleaning of multi-size grinding wheels. Background technique [0002] At present, during the grinding process of small hand-held grinders, because the surface of the grinding wheel is relatively rough, the fine particles under grinding are easy to adhere to the surface of the grinding wheel. The method is to manually blow off or brush off the surface grinding particles with the help of foreign objects after grinding for a period of time, but this kind of treatment method is more troublesome, so frequent operations will greatly affect the grinding process and affect the grinding efficiency of the workpiece. Contents of the invention [0003] The purpose of the present invention is to provide a hand-held grinding device suitable for one-key cleaning of multi-size grinding wheels, which can overcome the above-mentioned defe...
