Description
Technical field
The utility model belongs to Actuator technique field, is specifically related to a kind of electromagnetism pin removal.
Background technology
At present in Actuator technique field, the actuator with distribution or function of pulling pin especially used in armament systems, mostly is firer's actuator.Firer's actuator mainly relies on circuit function to complete powder burning, and the gas urges piston pin of generation has moved structure action, thus realizes the function promoting or pull pin.But also exist during the work of firer's actuator shock loading larger, inflammable and explosive, pollute that surrounding environment, security are low, single use, there is the not problem such as testability.
Utility model content
In order to overcome above defect or the Improvement requirement of the existence of firer's actuator, the utility model provides a kind of electromagnetism pin removal, has state and can detect, respond fast, repeatedly used feature.
A kind of electromagnetism pin removal, comprise housing, solenoid component, active component and pressure spiral shell, described active component is included in yoke, spring, armature, pin and the flux sleeve installed successively in the axial direction in housing, when electromagnetic force between armature and yoke is greater than the spring resistance between armature and yoke, yoke absorption armature motion, armature drives pin axially-movable; Solenoid component is set with between described housing and active component; Described pressure spiral shell is arranged on the end of housing near pin, for housing, solenoid component and active component being packaged as a whole.
Further, described solenoid component is made up of coil holder and circle enamel-covered wire, and described round enamel-covered wire is wound on coil holder, and there is cable hole one end of coil holder, and wire is drawn by the cable hole of coil holder one end after being connected with circle enamel-covered wire;
Further, matched in clearance between described armature and solenoid component, matched in clearance between described armature and flux sleeve, matched in clearance between described pin and pressure spiral shell.
Further, the endoporus periphery of the periphery of described armature, the periphery of pin, the endoporus periphery of wire reeling rack and flux sleeve all applies DJB-823 solid film protective agent.
Further, between described pin and armature, screw thread is fixedly connected with, and between described yoke and housing, screw thread is fixedly connected with.
Further, described armature and yoke adopt electromagnetic pure iron material.
Technique effect of the present utility model is embodied in:
At ordinary times, under the effect of spring resistance, pin stretches out outside housing.After giving the energising of the solenoid component on electromagnetism pin removal, solenoid component forms magnetic field, electromagnetic force is produced between the armature surrounded by solenoid component and yoke, when the electromagnetic force produced between armature and yoke is greater than the spring resistance between armature and yoke, yoke absorption armature motion, armature drives pin to move together.When after the power-off of electromagnetism pin removal, the electromagnetic force produced between armature and yoke disappears, and under spring resistance effect, is again stretched out outside housing by the pin pulled out back.The utility model structure is simple, and the electromagnetic attraction produced by the energising of electromagnetism pin removal overcomes spring resistance, realize pin pull out backhaul dynamic, have state can detect, respond fast, can the feature such as Reusability.
Further, matched in clearance between described armature and solenoid component, matched in clearance between described armature and flux sleeve, matched in clearance between described pin and pressure spiral shell, so adopts, and is conducive to armature and pin motion.And the endoporus periphery of the periphery of the periphery of armature, pin, solenoid component wire reeling rack and the endoporus periphery of flux sleeve all apply DJB-823 solid film protective agent.Employing like this, with the coefficient of friction of contact surface when can reduce armature and pin motion, reduction frictional resistance.
Further, during described electromagnetism pin removal energising, the electromagnetic force formed between described armature and yoke is greater than the drag of spring between armature and yoke.Employing like this, ensures that armature motion puts in place and the pin reliable movement that is connected with armature puts in place.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.In addition, if below in described each embodiment of the utility model involved technical characteristic do not form conflict each other and just can mutually combine.
As shown in Figure 1, embodiment of the present utility model, comprises housing 7, solenoid component 1, active component and pressure spiral shell 8.Active component comprises pin 2, armature 3, spring 4, yoke 5 and flux sleeve 6.In described housing 1, yoke 5, spring 4, armature 3, pin 2 and flux sleeve 6 are housed in the axial direction successively; Overlap between housing 7 and active component and have solenoid component 1, whole mechanism is packaged into one by pressure spiral shell 8.
As shown in Figure 2, described solenoid component 1 is made up of coil holder 1-1 and circle enamel-covered wire 1-2, and described round enamel-covered wire 1-2 is wound on coil holder 1-1, and there is cable hole one end of coil holder 1-1, and wire is drawn by the cable hole of coil holder 1-1 one end after being connected with circle enamel-covered wire 1-2.
Between described pin 2 and armature 3, screw thread is fixedly connected with; Described armature 3 and yoke 5 are made up of electromagnetic pure iron material; Described spring 4 is between described armature 3 and yoke 5; Between described yoke 5 and housing 7, screw thread is fixedly connected with.
Matched in clearance between described armature 3 and solenoid component 1, matched in clearance between described armature 3 and flux sleeve 6, matched in clearance between described pin 2 and pressure spiral shell 8, so adopts, is conducive to armature 3 and pin 2 moves.And the periphery of the periphery of armature 3, pin 2, the endoporus periphery of solenoid component 1 wire reeling rack 1-1 and the endoporus periphery of flux sleeve 6 all apply DJB-823 solid film protective agent.Employing like this, can reduce when armature 3 and pin 2 move and the coefficient of friction of contact surface, reduce frictional resistance.
