A material fixing device for machining with self-locking function

Abstract

The invention discloses a material fixing device for machining and with a self-locking function. The material fixing device comprises a mounting sleeve, a cross board, a fixing sleeve and a clamp; a vertical groove is formed inside the mounting sleeve; a self-locking groove is formed in the inner side of the mounting sleeve; a cross groove is preserved in the self-locking groove; the self-lockinggroove is mutually connected with the vertical groove through the cross groove and is internally and fixedly provided with a first permanent magnet; the clamp is provided with a limiting board and a first reset spring which are located on the inner side of a mounting groove; the clamp is mutually connected with the mounting groove through the first reset spring; and a third permanent magnet is installed on the clamp. According to the material fixing device for machining and with the self-locking function, the opposite repulsive force of the same magnetic poles of the first permanent magnet andthe third permanent magnet is used for pushing and locking the clamp, the phenomenon of getting loose in the material clamping process of the clamp is avoided, and the material clamping stability isimproved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a material fixing device for machining with a self-locking function. Background technique [0002] The machined material fixing device is generally a fixture for fixing the material, which is convenient for fixing the material and avoiding the displacement and loosening of the material. The traditional fixing device is generally fixed by bolts or adjusted by screw rods, and workers need to use tools to tighten. solid, low efficiency and increase the labor intensity of workers, and the traditional fixing device is prone to slippage during the process of fixing cylindrical materials. The traditional fixing device does not have a locking structure, so that after clamping the material It is prone to loosening, which can easily lead to material processing failure. Contents of the invention [0003] The object of the present invention is to provide a material fixing device for mac...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a material fixing device for machining with self-locking function, to solve the problem that the traditional fixing device proposed in the above-mentioned background technology has improved the labor intensity of the worker, and the traditional fixing device is used for cylindrical materials. Slippage is easy to occur during the fixing process. The traditional fixing device does not have a locking structure, which makes it easy to loosen after clamping the material, which easily leads to the failure of material processing.
