Novel electric file

Abstract

The invention relates to the technical field of electric files, and discloses a novel electric file which comprises a file main shell and a power box, a motor is fixedly connected to the inner wall of the file main shell, a rotating shaft is arranged at the output end of the motor, and a rotating head is fixedly connected to the end, away from the motor, of the rotating shaft; a three-jaw chuck is arranged at the end, away from the rotating shaft, of the rotating head part, a chuck is arranged on the inner surface of a hole groove in the right end of the three-jaw chuck, a rotating shaft is arranged in a containing cavity in the hole groove of the three-jaw chuck, and the end, penetrating through the three-jaw chuck, of the rotating shaft, extending into a containing cavity in the rotating head part is fixedly connected with an anti-disengaging block; the outer surface of the left end of the rotating shaft is in threaded connection with a threaded groove body, and the side face, away from the rotating shaft, of the threaded groove body is fixedly connected with a tool bit. Through cooperation of the structures, the workpiece machining efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric files, in particular to a novel electric file. Background technique [0002] The file is a common manual production tool used to file the workpiece in engineering processing, and is often used for micro-processing the surface of the metal. In the field of production maintenance, it includes the removal of rivets, and the removal of material on the surface of the workpiece, including the removal of some welds. [0003] Existing files can be divided into flat files, square files, semi-circular files, round files, triangular files, diamond files and knife-shaped files according to the cross-sectional shape. Flat files are used to file flat surfaces, outer round surfaces and convex arc surfaces; square files are used to file square holes, rectangular holes and narrow surfaces; triangular files are used to file inner corners, triangular holes and flat surfaces; semicircular files are used to file con...

Problems solved by technology

[0004] However, in an environment with a small space, it is even impossible to use a traditional file for processing or the efficiency is extremely low. In a slightly better environment, it is difficult for even skilled workers to control the strength and direction, and it is easy to cause operational errors to damage the workpiece. In light cases, the workpiece is damaged, or in severe cases, it is scrapped, or more time is spent on remediation, and the overall efficiency is low
