Electric permanent magnetic chuck controller with circuit break protection structure

Abstract

The invention discloses an electric permanent magnetic chuck controller with a circuit break protection structure. The controller comprises a permanent magnetic chuck controller body, an alarm assembly and a fixed slide rail. The alarm assembly is mounted in the middle of one side of the permanent magnetic chuck controller body, and the fixed slide rail is arranged in the permanent magnetic chuck controller body; and connecting pieces are installed at the front ends and the rear ends of the two sides of the fixed sliding rail correspondingly. Through the arrangement of a fixed sliding rail, a junction box a and a junction box b and the matched work of a limiting sliding groove, a good limiting effect can be achieved for a connecting rod, through the matched work of a gear column, a main track shoe, an auxiliary track shoe, a transmission rod and an adjusting knob, the gear column can be driven to rotate through the transmission rod, the gear column can be meshed with the top and the bottom of the surface of the main track shoe and the auxiliary track shoe so as to approach the middle, and the junction box a and the junction box b are matched to work so that the junction box a and the junction box b can play a better role in fixing the electric wire, the overall stability of the device is improved, and the phenomenon of open circuit can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of electro-permanent magnet chuck controllers, in particular to an electro-permanent magnet chuck controller with an open circuit protection structure. Background technique [0002] The electronically controlled permanent magnet chuck is a new type of fixture designed and developed in combination with the characteristics of electromagnetic and permanent magnets. It adopts a new type of magnetic chuck that uses electric pulses to "open and close". It is very safe and reliable during the process of holding the workpiece. After the workpiece is held by the magnetic force, the suction cup will maintain the magnetic suction indefinitely. It is widely used in CNC machining centers, milling machines, engraving machines, etc., but the existing electric permanent magnet The sucker controller still has certain deficiencies in actual use. [0003] The defective of existing a kind of electropermanent magnetic sucker co...

AI Technical Summary

Problems solved by technology

The electric permanent magnet chuck controller of the present invention can realize the normal magnetization and demagnetization operations of the electromagnetic chuck, and has two detection circuits and protection functions of load short circuit and open circuit detection, overcurrent detection, safe and reliable, and can effectively protect the circuit and Electromagnetic sucker; the pulse voltage for charging and demagnetizing the sucker is easy to obtain, and the charging and demagnetizing effects are remarkable, simple and practical", but the device does not have a good line collection and fixing structure, which makes the interior overall messy, which affects the use
