Abstract

The invention discloses an electro permanent magnet. The electro permanent magnet comprises a magnetic conductive shell and permanent magnetic pieces, and further comprises a coil assembly for generating an electromagnetic field and an electrical control assembly for controlling currents in the coil assembly, wherein the coil assembly is arranged in the shell in an insulated mode, and in the condition of material suction, the coil assembly keeps energized and the electromagnetic field and the permanent magnetic field are in the same direction. By means of the electro permanent magnet, through changing the currents in the coil assembly, superposition or disappearance of the magnetic field strength of a workbench can be achieved, operation is convenient, control is easy, and the automation degree is high.

Description

technical field [0001] The invention relates to the field of clamping equipment, in particular to an electric permanent magnet. Background technique [0002] In the field of machinery manufacturing, magnetic chucks that clamp workpieces through magnetic adsorption have been widely used due to their advantages in economy and environmental protection. [0003] At present, magnetic chucks have various specific forms such as permanent magnet chucks, electromagnet chucks, and electro-permanent magnetic chucks. A typical magnetic chuck is a permanent magnet chuck. This kind of permanent magnet chuck includes a fixed magnetic system and a movable magnetic system. The state of the movable magnetic system is changed by external force to realize the superposition or cancellation of the magnetic field strength on the workbench, so as to realize the treatment Suction or unloading of workpieces. [0004] However, this kind of magnetic chuck requires an external force to switch the magn...
