A linear direct-acting electromagnet

Abstract

A linear direct-moving electromagnet comprises an outer frame, a static iron core and a moving iron core, wherein the static iron core is coaxially arrange in the outer frame and a coil is wound on the static iron core; the moving iron core is coaxially fitted in the static iron core; the shaft core of the movable iron core is provided with a central rod penetrating the outer frame; one end of thecenter rod is a telescopic working end, and the other end thereof is a limit end for pushing the limit position; a rotary disk is sleeved on the working end; the rotary disk is movably connected withthe outer frame; a spiral inner ball groove is arranged in the shaft hole of the rotary disk, and the corresponding outer ball groove is arranged on the working end; a stainless steel ball is arranged between the inner ball groove and the outer ball groove; the rotary disk is provided with a lock head parallel to the working end; and the movable iron core performs expansion and contraction to drive the rotary disk to realize autorotation, and the lock head rotates around the working end. A locking structure capable of autorotation with the expansion and contraction of the push rod is added, and the locking structure is used for fitting in the specific locking structure, so that the locking ability can be increased, and the push rod can be protected from external force impact.

Description

technical field [0001] The invention relates to the field of electromagnet structure, in particular to a linear linear motion electromagnet. Background technique [0002] An electromagnet is a device that generates electromagnetism when energized. After inserting an iron core inside the coil, the iron core is magnetized by the magnetic field of the coil. The electromagnets on the market usually include a bracket, a coil and a telescopic rod. The bracket is fixedly connected to the coil. There are through holes on the bracket. The telescopic rod includes a push rod and a top sleeve. The setting of the through hole makes it easy for the electromagnet to enter impurities and water from the through hole during use. The impurities include oil stains, dust, etc. The water will accelerate the corrosion and rust of the moving parts. The impurities and rust will affect the smooth movement of the moving parts. Ultimately, the electromagnet cannot work normally, so it needs to be dism...

The electromagnets on the market usually include a bracket, a coil and a telescopic rod. The bracket is fixedly connected to the coil. There are through holes on the bracket. The telescopic rod includes a push rod and a top sleeve. The setting of the through hole makes it easy for the electromagnet to enter impurities and water from the through hole during use. The impurities include oil stains, dust, etc. The water will accelerate the corrosion and rust of the moving parts, and the impurities and rust will affect the smooth movement of the moving parts. Ultimately, the electromagnet will not work properly, requiring disassembly and replacement, wasting manpower and resources
