Integrally formed electromagneto chuck

Abstract

The invention discloses an integrally formed electromagneto chuck which is applied to injection molding machine quick-change mold systems, grinding machines, CNC machining and other machining. The integrally formed electromagneto chuck comprises a magnetic chuck body, a temperature sensor, a magnetic flux sensor, a proximity sensor, a sensor integrated base, sensor connecting lines, a magnetic chuck power input socket, a mounting groove, a field core, permanent-magnet steel, reversible magnet steel, a magnet exciting coil, a magnetic conductive block and the like. The magnetic face of the magnetic chuck body is integrally formed, the leakproofness is good, water is prevented from entering the magnetic chuck body, the electric leakage phenomenon of the magnet exciting coil in the magnetic chuck body is prevented, compared with common electromagneto disks, the strength of the magnetic face is greatly increased, the service life of the magnetic chuck body is prolonged, various working states of the magnetic chuck body are sensed by arranging the multiple sensors, molds can be rapidly clamped and rapidly discharged through the electromagneto chuck, the magnetic conductive efficiency is high, magnet is high, and magnetic attractive force is high and reaches 15-19 kilograms per square centimeter.

Description

technical field [0001] The invention relates to an integrally formed electric permanent magnetic chuck. Background technique [0002] At present, most of the disk surface structures on the market are equipped with grooves to install the excitation coil, reversible magnet, permanent magnet and excitation core. When the excitation coil, reversible magnet, permanent magnet and excitation core are installed After the completion, the staff pours sealant into the groove. Since the groove is filled with sealant, when the disk is heated up, the sealing effect between the sealant and the disk is poor, causing the disk to easily enter water and easily cause excitation inside the disk. The coil leaks electricity, which affects the service life of the disk, and the existing disk does not have the function of automatic induction detection, resulting in poor positioning accuracy, poor magnetic effect, weak magnetic attraction, and small magnetic attraction. The magnetic force of the magn...

The coil leaks electricity, which affects the service life of the disk, and the existing disk does not have the function of automatic induction detection, resulting in poor positioning accuracy, poor magnetic effect, weak magnetic attraction, and small magnetic attraction. The magnetic attraction force of the disk is generally only 10KG-15KG
