Abstract

The invention provides a pneumatic filing machine. The machine is characterized in that a piston rod set leftwards and rightwards reciprocate by a pneumatic technology; a file is mounted at the end part of a first piston cover; an air source is connected, and then an air valve is pressed, and the file can leftwards and rightwards reciprocate. With the adoption of the machine, the working efficiency is improved, and meanwhile, the working intensity of workers is reduced; and the machine is humanized.

Description

technical field [0001] The invention relates to the field of pneumatic technology, in particular to a pneumatic filing machine. Background technique [0002] Existing files all use manpower to file workpieces, and the efficiency of workers is low when they are used, and after a period of use, workers are prone to arm pain and fatigue, further reducing efficiency, and easily causing occupational diseases such as frozen shoulder. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pneumatic file machine, which is driven pneumatically to realize the linear reciprocating movement of the piston rod group, and the automatic movement of the file can be realized after the file is fixedly connected to the piston rod group to improve efficiency. At the same time, it reduces the labor intensity of workers and is more humane. [0004] The present invention is realized as follows: a pneumatic file machine, which also includes ...
