Abstract
The utility model relates to an electromagnetic locator, composed of a movable component and a fixed component. The movable component is provided with a permanent magnet. The fixed component is provided with ferromagnetic material and a DC electromagnet. Magnetic field which has an opposite polarity with the permanent magnet is generated by the current direction in an electromagnet coil. The moveable component and the fixed component are attracted by the attracting force of the permanent magnet and ferromagnetic material. The moveable component and the fixed component are separated by repulsion of a magnetic field generated by an electromagnet is opposite to the magnetic field generated by the permanent magnet. Automatic control, distant place or electric control on the spot can be realized and electricity is saved.
Description
The design belongs to the mechanical device that is used to discharge the back mobile member, especially for the electromagnetic type positioner of realizing the stroke terminal location on the MOVING STRUCTURE.
The action principle of the stroke positioner of existing various MOVING STRUCTUREs (as machinery, lathe, vehicle, door and window etc.) roughly is divided three classes:
Mechanical type: realize the location by alignment pin, locator card, spring latch lock and various snap close.Its shortcoming is to adopt telemechanical or automatically when returning.
Magnetic-type: realize the location by permanent magnet and the mutual adhesive of ferrimagnet that is contained in respectively on MOVING STRUCTURE and the stroke end fixed position.Shortcoming is can only armrest when returning moving equally, can't realize telemechanical or automatically.
Electromagnetic type: exchange on MOVING STRUCTURE and the stroke end fixed position or DC electromagnet and the mutual adhesive of ferrimagnet realize the location by being contained in respectively.Shortcoming is that the AC and DC electromagnet needs often to keep energising, operating cost height.
The design's purpose provides a kind of novel stroke positioner, makes it can possess telemechanical or automatic function, overcomes the shortcoming of mechanical type and magnetic-type; Simultaneously can also power saving, overcome the shortcoming of electromagnetic type.
The design's content is on the movable member in travel control system permanent magnet to be housed.The ferrimagnet that connects electromagnet is housed on fixed part, and electromagnet is a DC electromagnet, and the direct current direction should make the magnetic field of electromagnet generation and permanent magnet reversed polarity.
The design is a kind of electromagnetic location device, is different from mechanical positioner.The substantive distinguishing features of this device is to adorn permanent magnet on moving-member, and adorns the ferrimagnet that connects electromagnet on fixed part, both has been different from magnetic-type, also is different from the structure of electromagnetic type device.The design's advantage is to connect the electric current of DC electromagnet, can make mobile position break away from the location, can accomplish automatically or telemechanical.Second advantage of the design is to adsorb the magneticaction that the location utilizes permanent magnet and ferrimagnet, needs the moment energising when only breaking away from the location at mobile position, so power saving, overcomes the shortcoming of electromagnetic type.
The design's embodiment is as shown in drawings:
The description of the drawings:
Movable member is formed by a permanent magnet 1 with the permanent magnet base 2 that non-magnetic conduction material is made.Base leaves installing hole and can be fixed on the MOVING STRUCTURE with screw.
Fixed part is made up of dc coil 4, iron core 5, electromagnet pole plate 6 and electromagnet stent 8, has yielding rubber 3 on electromagnet pole plate 6.Iron core, pole plate and support are all made with the low-carbon (LC) electrical sheet.Have installing hole on the support 8, so that be installed in suitable fixedly status with screw.
The using method of present embodiment is that when MOVING STRUCTURE was shifted to the stroke end, the movable member internal permanent magnet was just inhaled mutually by the electromagnet pole plate on the fixed part and located.Rubber blanket plays buffering, shock resistance effect, in case permanent magnet is shatter, and makes magnetic circuit have the gap, is convenient to separate.
When moving-member will return, can make it to produce and the mutually diamagnetic magnetic field of permanent magnet to the logical direct current of electromagnet, make movable member push away fixed part by magnetic repulsion.Transmission device by MOVING STRUCTURE self returns it then, adopts suitable control circuit, just can realize a distant place or electric operating and control on the spot automatically.Losing under the power supply situation, also availablely manually making its location or separation.
Claims (1)
- A kind of stroke positioner, comprise movable member and fixed part two parts, it is characterized in that being equipped with on the movable member permanent magnet material, ferrimagnet and DC electromagnet are housed on the fixed part, and the sense of current that feeds the direct solenoid iron coil makes the magnetic field of electromagnet generation and permanent magnet material reversed polarity.
