Description
Technical Field
The present invention relates to an electromagnet, and more particularly to a holding electromagnet. Background
In the prior art, the magnetic field of the electromagnet is generated by electrifying current, the electromagnet can only have the magnetic field when being electrified, the magnetic field disappears immediately after the power failure, if an iron core of the electromagnet is required to be kept at the electrified position, the electrifying current needs to be kept, and under the condition of long-time operation, the electromagnet not only consumes large power, but also generates heat seriously.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a simple structure and low energy consumption keep-type electromagnet. The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted as follows:
a holding electromagnet comprises a rectangular shell and a movable iron core; the movable iron core is arranged in the rectangular shell, a permanent magnet is arranged between the movable iron core and the rectangular shell, and a guide hole is formed in the permanent magnet; the movable iron core and the coil are coaxially arranged, one end of the movable iron core is provided with a guide shaft, the guide shaft and a guide hole of the permanent magnet are coaxially arranged, a position blocking piece is arranged at a position, extending out of the rectangular shell, of the guide shaft, and a photoelectric switch is arranged at a position matched with the position blocking piece; and a limiting baffle plate is arranged on the part of the other end of the movable iron core, which extends out of the rectangular shell, and a limiting spring is arranged between the rectangular shell and the limiting baffle plate.
The utility model has the advantages that: the holding electromagnet of the utility model is provided with the permanent magnet, when the coil is powered off, the movable iron core can still keep the position of power-on unchanged under the action of the magnetic field of the permanent magnet; in the equipment that has the requirement to the outage, it is especially important, can avoid the emergence of some production accidents, because the utility model discloses only need with the pulse mode power supply, the event has reduced the consumption of electric energy.

Detailed Description
Referring to fig. 1, a holding type electromagnet includes a rectangular housing 1 and a movable iron core 2; the movable iron core 2 is arranged in the rectangular shell 1, a permanent magnet 4 is arranged between the movable iron core 2 and the rectangular shell 1, and a guide hole is formed in the permanent magnet 4; the movable iron core 2 and the coil 3 are coaxially arranged, one end of the movable iron core 2 is provided with a guide shaft 5, the guide shaft 5 and a guide hole of the permanent magnet 4 are coaxially arranged, a position blocking piece 8 is arranged at the position where the guide shaft 5 extends out of the rectangular shell 1, and a photoelectric switch 9 is arranged at the position matched with the position blocking piece 8; the other end of the movable iron core 2 is provided with a limit stop 6 extending out of the rectangular shell 1, and a limit spring 7 is arranged between the rectangular shell 1 and the limit stop 6.
The working principle of the embodiment is as follows:
in fig. 1, when a forward voltage is applied to the coil 3 of the holding electromagnet, the movable iron core 2 generates a forward axial linear motion against the tension of the spring, so that the position stopper 8 moves to the position of the photoelectric switch 9, the photoelectric switch 9 automatically cuts off the forward current of the holding electromagnet coil 3, and the position of the movable iron core 2 is kept unchanged by the magnetic field relay of the permanent magnet 4.
In fig. 2, when the holding electromagnet coil 3 applies a reverse voltage, the movable iron core 2 generates a reverse axial linear motion and moves reversely to the working position against the magnetic field of the permanent magnet 4, and the movable iron core 2 is held at the working position by the tension of the limit spring 7.
Of course, those skilled in the art should realize that the above-mentioned embodiments are only used for illustrating the present invention, and not for limiting the present invention, and that all the changes and modifications to the above-mentioned embodiments are within the scope of the appended claims as long as they are within the true spirit of the present invention.
