Description

A kind of Self-retaining electromagnet of built-in two-way position detection
Technical field
The present invention relates to electromagnet manufacturing technology field, especially a kind of self-sustaining electromagnetism of built-in two-way position detection Iron.
Background technology
In the fuze mechanisms such as rocket projectile, shell, mechanical position limitation protection and its releasing are carried out usually using electromagnet, this is just It is required that electromagnet, which has, can carry out two-way position detection, the features such as self-holding force is big, state switching time is short, and prior art Electromagnet can not carry out two-way position detection, i.e., two location status can not be represented by Continuity signal, existed in addition Self-holding force, it need further raising in terms of switching time.
In addition, the magnetic-holding electric magnet of existing carrier state detection, electromagnet is promoted when its state-detection is by armature motion Whether internal movable contact spring, made being switched on or switched off for movable contact spring and static contact spring piece, judged the state of electromagnet in required with this State.And the movable contact spring and static contact spring piece of state-detection are positioned over outside electromagnet ontology, connected by additional case and body Connect.This structure greatly increases the volume and quality of electromagnet.
The content of the invention
It is an object of the invention to make up in place of the deficiencies in the prior art that there is provided one kind two location status can be realized Represented by Continuity signal, and improve self-holding force and shorten the self-sustaining electricity of the built-in two-way position detection of switching time Magnet.
The purpose of the present invention is realized by following technological means：
A kind of Self-retaining electromagnet of built-in two-way position detection, it is characterised in that：Including output shaft, piston, upper end cover, Bottom end cover, guide, magnet steel, coil rack, coil and housing, the upper end of output shaft are installed on upper end cover vertically, output shaft The coaxially connected piston in lower end, bottom end cover is located at the lower section of piston, and guide, magnet steel, coil are sequentially coaxially set with the outside of piston Skeleton, coil and housing, above-mentioned guide, magnet steel, coil rack, coil and housing be respectively positioned on upper end cover and bottom end cover it Between, and the top and bottom of housing are connected with upper end cover and bottom end cover respectively；Magnet steel includes upper magnetic steel and lower magnetic steel, the upper magnetic steel It is setting up and down and polarity is relative with lower magnetic steel；Felt pad and upper contact switch are embedded with the bottom surface of upper end cover, in lower end The upper surface of lid is embedded with lower felt pad and lower contact switch.
Moreover, make a fairlead on described upper end cover, the lead of upper contact switch, the lead of lower contact switch with And the lead of coil is drawn from the fairlead of upper end cover.
Moreover, described upper end cover, bottom end cover, piston and housing are permeability magnetic material, described output shaft is non-magnetic Material.
Advantages and positive effects of the present invention are：
1st, in the present invention piston and output shaft connection, constitute movable part.When piston self-insurance is held at upper end cover, it is touched Contact switch is turned it in pressure upper end cover, and now contact switch disconnects in bottom end cover；When piston self-insurance is held at bottom end cover, its Press contact switch in bottom end cover to turn it on, now contact switch disconnects in upper end cover.By this structure design so that this electricity Magnet can be represented two location status by Continuity signal.
2nd, upper end cover of the invention, bottom end cover, piston, housing use permeability magnetic material, so as to constitute magnetic circuit and realize magnetic Shielding.
3rd, the output shaft in the present invention is non-magnet material, can improve self-holding force.
4th, the present invention realizes that electromagnet armature stretches out or retracted two location status, by detecting Continuity signal come table Show, reduce the volume of electromagnet, quality mitigates.
5th, the present invention is the built-in two-way position of a kind of reasonable in design, scientific structure, easy to use, small volume, light weight The Self-retaining electromagnet of detection, this electromagnet not only realizes two location status and represented by Continuity signal, and Also improve self-holding force and shorten switching time, meet the use requirement of the fuze mechanisms such as rocket projectile, shell.

Embodiment
Describe embodiments of the invention in detail below in conjunction with the accompanying drawings；It should be noted that the present embodiment is narrative, no It is limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of Self-retaining electromagnet of built-in two-way position detection, including output shaft 10, piston 11, upper end cover 7, bottom end cover 1st, guide 14, magnet steel, coil rack 6, coil 5 and housing 2, described upper end cover, bottom end cover, piston and housing is magnetic conduction material Material, described output shaft is non-magnet material.
The upper end of output shaft is installed on upper end cover vertically, the coaxially connected piston in lower end of output shaft, and bottom end cover, which is located at, lives The lower section of plug.Piston connects and composes movable part with output shaft, and position switching is carried out between upper end cover and bottom end cover.In piston Outside be sequentially coaxially set with guide, magnet steel, coil rack, coil and housing, above-mentioned guide, magnet steel, coil rack, coil And housing is respectively positioned between upper end cover and bottom end cover, and the top and bottom of housing are connected with upper end cover and bottom end cover respectively. Magnet steel includes upper magnetic steel 12 and lower magnetic steel 13, the upper magnetic steel and lower magnetic steel is setting up and down and polarity is relative.
Felt pad 9 and upper contact switch 8 are embedded with the bottom surface of upper end cover, under being embedded with the upper surface of bottom end cover Felt pad 3 and lower contact switch 4.A fairlead, lead 17, the lower contact of upper contact switch 8 are made on described upper end cover The lead 15 of switch 4 and the lead 16 of coil are drawn from the fairlead of upper end cover.
The operation principle of the present invention：
During power-off, magnet steel magnetizes upper and lower end cap and piston, and upper and lower end cap has suction to piston, because piston is close End cap it is big to its suction, therefore piston is attracted at its close end cap, realizes self-sustaining.Now, piston presses the end The contact switch being embedded in lid, is at conducting state, and the contact switch of opposite side is off, and then passes through two The state of individual contact switch realizes reliable position detection.When applying direct impulse electric current to coil, the magnetic that electric current is produced Field and magnet steel magnetic field superposition, strengthen upper end cover magnetization degree, weaken bottom end cover magnetization degree, if piston is at bottom end cover, The suction of upper end cover overcomes the suction of bottom end cover, and piston is adsorbed at upper end cover, realizes that position switches, output shaft is pushed out； Equally, when applying negative-going pulse electric current to coil, piston is adsorbed at bottom end cover by upper end cover, and output shaft is pulled.
Above-described embodiment is served only for that the present invention will be described, and is not construed as limiting the scope of claims limitation, thus it is all with The equivalent variations that content described in the claims in the present invention is done, all fall in the scope of protection of the present invention.
