Description

Technical Field

[0001] The utility model relates to the technical field of electro-permanent magnets, and more specifically, to an expandable electro-permanent magnet. Background Art

[0002] An electro-permanent magnet, also known as an electronically controlled permanent magnet, is a magnet controlled by electricity. Its core lies in controlling and converting the distribution of the internal magnetic circuit through an electronic control system to achieve magnetization and demagnetization of the magnetic field.

[0003] Currently, during the processing of large sheet metal parts, a lifting device is often required to lift the large sheet metal parts so as to move them to the processing area. A common lifting method is to connect the sheet metal parts with steel cables and lift them with a lifting device. However, since the surface of the unprocessed large sheet metal parts usually does not have the conditions for connecting the steel cables, the connection between the large sheet metal parts and the steel beam can be achieved by the magnetic attraction of an electromagnet, thus facilitating lifting. However, traditional electromagnets are not convenient for expansion to adjust the magnetic attraction force on the large sheet metal parts, thereby affecting the stability of lifting the large sheet metal parts. In view of this, we propose an expandable electro-permanent magnet. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide an expandable electro-permanent magnet to solve the technical problem that the current traditional electromagnet is not convenient for expansion to adjust the magnetic attraction force on the large sheet metal parts, thereby affecting the stability of lifting the large sheet metal parts.

[0005] To solve the above technical problem, the utility model provides the following technical solution: an expandable electro-permanent magnet, including a magnetizing component that can be detachably connected;

[0006] A connecting component is detachably connected between the magnetizing components, and the magnetizing component includes an outer shell;

[0007] The connecting component includes symmetrically arranged mounting plates. A connecting plate is centrally constructed and connected between the mounting plates. An installation groove is centrally formed inside the connecting plate. A knob is rotatably installed on one side of the mounting plate. One end of the knob is centrally constructed with a bidirectional screw rod that is rotatably installed in the installation groove. Connecting parts are symmetrically and movably installed on the outer edge surface of the bidirectional screw rod;

[0008] The connecting part includes a slider that is movably engaged with the bidirectional screw rod. Positioning plates are constructed and connected at both ends of the slider. A limiting convex plate is centrally constructed on one side of the positioning plate;

[0009] Positioning grooves are formed at both side edge positions of the outer shell. A limiting groove adapted to the clamping of the limiting convex plate extends towards the inside of the outer shell in the middle of the positioning groove.

[0010] The utility model realizes the connection between magnetic attraction components by designing a positioning plate and a limiting convex plate. By rotating the knob, the bidirectional lead screw can be rotated, thereby driving the symmetrically arranged connecting components to move towards each other, so that the positioning plate and the limiting convex plate are respectively clamped in the positioning groove and the limiting groove, thereby realizing the connection between the magnetic attraction components. The magnetic attraction components can be infinitely expanded according to the connecting components, so as to conveniently adjust the magnetic attraction force on large sheet metal parts and improve the stability of lifting large sheet metal parts.

[0011] Preferably, V-shaped insertion plates are formed on both sides of the outer shell body, and the V-shaped insertion plates on both sides of the outer shell body are arranged in a mirror-image staggered manner.

[0012] Preferably, V-shaped slots are symmetrically formed inside the connecting plate, and the V-shaped insertion plates are detachably inserted and installed in the V-shaped slots.

[0013] Preferably, sliding grooves are symmetrically formed inside the mounting plate, and a sliding shaft is fixedly installed in the middle of the sliding grooves.

[0014] Preferably, positioning blocks are symmetrically connected between the positioning plates and are adaptively slidably installed on the outer edge surface of the sliding shaft. A shaft hole adapted to install the sliding shaft is formed inside the positioning block.

[0015] Preferably, electromagnet bodies are arranged in an array distribution inside the outer shell body, and a grid filling frame is filled between the electromagnet bodies and between the electromagnet bodies and the outer shell body.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The utility model realizes the connection between magnetic attraction components by designing a positioning plate and a limiting convex plate. By rotating the knob, the bidirectional lead screw can be rotated, thereby driving the symmetrically arranged connecting components to move towards each other, so that the positioning plate and the limiting convex plate are respectively clamped in the positioning groove and the limiting groove, thereby realizing the connection between the magnetic attraction components. The magnetic attraction components can be infinitely expanded according to the connecting components, so as to conveniently adjust the magnetic attraction force on large sheet metal parts and improve the stability of lifting large sheet metal parts, and solves the problem that the traditional electromagnet is not easy to expand to adjust the magnetic attraction force on large sheet metal parts, thereby affecting the stability of lifting large sheet metal parts.

[0018] 2. The utility model also designs a limiting convex plate. The convex structure of the limiting convex plate is beneficial to form a gradient clamping force on both sides of the outer shell body, that is, the clamping cooperation with the positioning plate and the positioning groove further improves the stability of the extended connection between the magnetic attraction components, and the convex structure of the limiting convex plate has a larger contact area compared with the plane structure, thereby further ensuring the stability of the extended connection between the magnetic attraction components.
