Abstract
The utility model discloses an electromagnetic driving means. The utility model is composed of an iron core with a coil, a magnetic armature iron, a tension spring and a switch circuit which is connected with the coil. The utility model is characterized in that the armature iron is made of soft magnetic material; a permanent magnetism block is inlaid on the armature iron; the magnet pole surface of the magnetism block is adsorbed with adjustment sheets with different thickness. The utility model extends the service life of the product, improves the yield rate of the product, and reduces the cost of the product.
Description
The utility model discloses a kind of electromagnetic actuators, particularly relate to a kind of electromagnetic actuators with armature.
Chinese patent ZL94225903.3 discloses a kind of electromagnetic traction mechanism, it is by iron core, coil on the iron core, armature constitutes with the extension spring that is connected with armature, its main feature is to change common armature into permanent magnet, coil connects a polarity reversing switch circuit, and the electrical power that coil must consume when the common electrical magnetic actuator was kept adhesive has been saved fully in the electromagnetic traction mechanism of this structure, has reached energy-efficient and has eliminated the noise because of the mechanical oscillation generation of attracting state fully.But there is following defective in practice in the actuator of this structure:
1, armature is permanent magnet, and the magnetic flux of magnet and magnetic flux density play an important role to adhesive, the disjunction of mechanism: the suction-combining force is strong, is difficult to divide disconnect; The suction-combining force is weak, the adhesive instability, and unreliable, slight vibration is promptly separable.Because in batch production is difficult to the parameter of magnet is strict controlled within the needed scope, thereby rate of finished products is low when manufacturing, and properties of product are widely different simultaneously.
2, present employed permanent magnet or title magnet steel, from material itself, hardness is very high, but very crisp.Armature collides with iron core in attracting process, and impulsive force is very big, and armature is very easily broken, cause mechanism to damage and scrap, simultaneously because of the armature geometry variation, the hardness height, processing difficulties and is pulled being connected and fixed of parts and also becomes a difficult problem, brings very big trouble to manufacturing process.
3, because integral armature is a permanent magnet, the material price height, about 0.4 yuan/gram, higher tens times than iron plate or silicon steel sheet price 0.01 yuan/gram, improved the cost and the cost of actuator greatly.
Goal of the invention of the present utility model is to provide a kind of can overcome the defective that above-mentioned technology exists, and armature magnetic flux and magnetic flux density are adjustable and the electromagnetic actuators of impact resistance.
Goal of the invention of the present utility model is achieved in that on the basis of prior art, change the armature of actuator permanent magnet into make armature by soft magnetic material (as iron, silicon steel sheet etc.), on armature, inlay permanent magnetic patch, armature is produced and the corresponding magnetic pole of iron core polarity, the soft magnetism adjustment sheet of different-thickness is adsorbed on the magnetic pole strength of magnetic patch and adjusts adjustment sheet, thereby reaches the purpose of adjusting the armature magnetic induction.
The utility model is because employing is inlayed magnetic patch on soft magnetism armature, and on the magnetic pole end face of magnetic patch the increase and decrease soft magnetic material structure, thereby the shape that can reach magnetic patch is unified, to the requirement of magnetic patch magnetic flux, has improved the rate of finished products of product in the reduction course of processing; In addition, this mosaic texture can be avoided the direct contact-impact of magnetic patch and iron core, prolongs the life-span of product; The 3rd, the most of soft magnetic material that adopts of armature, handling ease, technology is simple, and cost reduces greatly.
Below with reference to accompanying drawing the utility model is done further detailed description.
Fig. 1 is the utility model
The structural representation of shape electromagnetic actuators.
Fig. 2 is the structural representation of the utility model " U " shape electromagnetic actuators.
Referring to Fig. 1.
Have coil (2) on the iron core of shape (1), with the shape of iron core (2) corresponding "
" shape armature (3) is made up of iron plate, the end of pole shoe (4) is inlayed magnet steel (5) in the middle of the armature, and the gap between the middle pole shoe (6) of magnet steel (6) and iron core (1) is 0.5-1.6mm.Adjust gap between the two by dosing iron plate (6), reach the purpose of adjusting magnetic flux density, guarantee that the armature and the suction-combining force of iron core meet the requirements prescribed, simultaneously, guarantee in the armature magnet steel directly and iron core collide, avoid the fragmentation of magnet steel.
Referring to Fig. 2.Has coil (12) on the U-iron core (11) of " U " shape electromagnetic actuators, form by iron plate with iron core (11) shape corresponding " ∩ " shape armature (13), magnet steel (16) is inlayed at the position between armature bipolar shoe (14), (15), and the gap between it and bipolar shoe (14), (15) is between the 0.5-1.5mm.By dosing the size of sand steel disc (17) adjusting play, reach the purpose of adjusting magnetic flux density; Also avoided simultaneously the direct collision between magnet steel and the iron core.
