Electromagnetic fixator

Abstract

The invention discloses an electromagnetic fixator. The electromagnetic fixator is characterized in that the working principle that an electromagnet and a permanent magnet are repellent in the same direction and are attractive in the different directions is adopted; the electromagnet is arranged at the front end of a lock tongue; a clamping groove is formed in a permanent magnet seat; when a current is controlled to enable the electromagnet and the permanent magnet to attract each other, the lock tongue drives a core barrel to downwards slide in the axial direction of a core rod to stretch out of a sleeve, and the lock tongue is completely clamped in the clamping groove and is fixed; when the current direction is changed, the electromagnet and the permanent magnet are repellent, the lock tongue drives the core barrel to upwards slide in the axial direction of the core rod to be collected in the sleeve, the lock tongue is separated from the clamping groove and is released, and fixation and release function needs of the electromagnetic fixator are effectively achieved; a fixed seat is detachably connected on the surface of a moving part, a groove matched with the permanent magnet seat is formed in the surface of a relative static part, and mounting can be achieved and is easy; a control unit integratedly controls all electrical elements; and the electromagnetic fixator has the characteristics of convenient utilization, firm fixation and high practicability.

Description

technical field [0001] The invention relates to the technical field of mountable and detachable fixing machines, in particular to an electromagnetic fixer. Background technique [0002] In many mechanical products, it involves the structural design problem that the moving unit and the static unit need to be fixed. For example, mobile platforms, sliding guide rails or turntables, when the moving parts need to be structurally fixed after the movement is completed, in order to prevent the moving parts from slipping without human control due to their own gravity or other external forces, resulting in unforeseen circumstances. Predicted component damage and damage, resulting in related safety accidents. Especially in the case of high motion precision requirements, such as high-precision turntable, it is necessary to strictly protect its motion contact parts. If the moving parts shift or slide, it will seriously affect its motion accuracy. There is a rotating handle, that is, ma...

Problems solved by technology

Especially in the case of high motion precision requirements, such as high-precision turntable, it is necessary to strictly protect its motion contact parts. If the moving parts shift or slide, it will seriously affect its motion accuracy. There is a rotating handle, that is, manpower is required to manually operate the handle to fix and loosen, which is time-consuming and troublesome, and there is also the problem of unreliable fixing
