Pneumatic polishing pen

Abstract

The invention discloses a pneumatic grinding pen, comprising a switch group, one end of the switch group is screwed with an air inlet joint, the upper end of the switch group is connected with a switch handle through a rotating shaft, and the other end of the switch group is screwed with a motor tube body , the inside of the motor pipe body is provided with a cylinder motor group, one end of the cylinder motor group is embedded with a positioning pin, one end of the positioning pin is connected to the switch group, and one end of the switch group is screwed with a shaft casing, and the shaft casing One end is embedded with a first bearing, and the other end of the rotating shaft casing is embedded with a fourth bearing matching the first bearing. A rotating shaft is connected between the first bearing and the fourth bearing, and a locking mechanism is provided on one side of the rotating shaft. , the outer side of the locking mechanism is connected with a front-end pipe body, one end of the rotating shaft is screwed with a flat nut, and the other end of the rotating shaft is provided with a mating female head. The internal structure of the present invention is simple, relatively easy to assemble, and convenient for disassembly and maintenance. Maintenance, high machining accuracy.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a pneumatic grinding pen. Background technique [0002] Die engraving machines are widely used in the grinding, polishing, trimming and shaping of various moulds, glass products, stone materials, handicrafts, etc. Die engraving machines are electric or pneumatic. Lightweight, fast running and other advantages, it has been widely used. The pneumatic market should have a bright future, and the failure rate of pneumatics is low, because the electric ones generally fail to replace the carbon brushes in time, causing the rotors to be scrapped and damaged directly. Grinding machines are widely used in the industry, but most of them are electric at present. Pneumatic market potential is great but needs to be tapped. In addition, most of the existing pneumatic grinding pens work with compressed air at a high speed, which produces relatively high noise, which also gives a The user has bro...

Problems solved by technology

The pneumatic market should have a bright future, and the failure rate of pneumatics is low, because the electric rotors are generally scrapped and damaged because the carbon brushes are not replaced in time. Grinding machines are widely used in the industry, but most of them are electric at present. Pneumatic market potential is great but needs to be tapped, and most of the existing pneumatic grinding pens work with compressed air at a high speed, which produces relatively high noise, which also gives users bring some trouble
