Thereby greatly reducing the workload and improving the production efficiency of the magnetic horse board.

The technical solution adopted by the present invention to solve its technical problems is:

A portable magnetic horse plate used for steel plate assembly and welding, mainly composed of a handle, two permanent magnetic suction cups and a horse frame connecting the two permanent magnetic suction cups, two permanent magnets are arranged in the permanent magnetic suction cups, The permanent magnetic suction cup is provided with a suction cup switch connected with one of the permanent magnets, and the handle is provided with a pulling end matched with the suction cup switch.

The permanent magnetic chuck is provided with threaded holes, and the two ends of the horse stand are provided with threaded connection parts matching the threaded holes.

The horse frame is composed of a first hinged part and a second hinged part, one end of the first hinged part and the second hinged part are hinged, and the threaded connection part is arranged at the free ends of the first hinged part and the second hinged part .

The beneficial effects of the present invention are: the magnetic horse plate of the present invention is mainly composed of a handle, two permanent magnetic suction cups and a horse frame, each part is independent of each other, and the combination is flexible and convenient, and the magnetic horse plate and the welded steel plate are fixed completely by the permanent magnetic suction cup Magnetic force, without the cooperation of other auxiliary equipment, a single person can directly use both hands to install and remove, which is flexible and convenient, thereby improving the work efficiency of steel plate assembly in the construction process. Since there is no welding, there is no trace on the surface of the base metal, and it is not harmful to the base metal. If there is any impact, there is no need for any treatment, which can reduce the workload of grinding in the construction process, reduce production costs and labor intensity, and have a high operating safety factor without any potential safety hazards. It is suitable for the butt joint and angle of steel plates in steel plate tailor welding. Fixation of different connection forms in different parts.

Detailed ways

A portable magnetic horse plate used for steel plate assembly and welding, the first embodiment refers to Figure 1 and Figure 2, it mainly consists of a handle 4, two permanent magnetic chucks 2 and a horse frame connecting the two permanent magnetic chucks 1, the permanent magnetic chuck 2 is provided with two permanent magnets, the permanent magnetic chuck 2 is provided with a suction cup switch 20 connected to one of the permanent magnets, and the handle 4 is provided with a suction cup switch 20 matching Pulling end 40, in this embodiment, the end of suction cup switch 20 is hexagonal column shape, and the end surface of pulling end 40 is provided with the hexagonal indentation that adapts to the shape of suction cup switch, and the hexagonal indentation is set on the end of suction cup switch 20. Move handle 4 and just can drive sucker switch 20 to rotate.

The structure of the permanent magnet chuck 2 belongs to the prior art, and is also called a magnetic suspension pan, a permanent magnet lifter, a magnetic force suspension, etc. in the prior art. The permanent magnetic chuck is made of high-performance rare earth material NdFeB (N>40) as a permanent magnetic material to form a strong magnetic system. The handle is turned by hand to drive the rotation of the suction cup switch 20, thereby driving one of the permanent magnets to rotate, changing the neodymium inside the suction cup. The magnetic system of the iron-boron strong magnetic system achieves the holding or releasing of the welded steel plate. The permanent magnetic chuck is designed by using the principle of continuity of magnetic flux and the principle of superposition of magnetic field. The magnetic circuit of the permanent magnetic chuck is designed into multiple magnetic systems. Elimination, so as to achieve the purpose of holding and unloading.

The permanent magnetic chuck 2 is provided with a threaded hole 21, and the two ends of the horse frame 1 are provided with a threaded connection portion 10 matching the threaded hole 21, and the permanent magnetic chuck 2 and the horse frame 1 are connected by threads to facilitate disassembly Another advantage of threaded connection is that the height difference between the lower surfaces of the two permanent magnetic chucks can be adjusted, which facilitates the combination of rigid horse frames of different shapes and is suitable for fixing steel plates of different thicknesses.

Referring to Fig. 3 and Fig. 4 for the second embodiment, the difference between the magnetic horse board of this structure and the first embodiment is only the structure of the horse frame. The horse frame of the first embodiment is a fixed structure, only It is suitable for the butt joint of two steel plates A and B as shown in Figure 3 and the right-angle joint of two steel plates A and B as shown in Figure 4. It is not suitable for the assembly of steel plates at any angle. The second embodiment uses movable machinery The horse stand not only possesses the functions of the first embodiment, but also just makes up for the deficiencies of the first embodiment.

Referring to Fig. 5 and Fig. 6, the movable mechanical horse frame is composed of a first hinged part 11 and a second hinged part 12, one end of the first hinged part 11 and the second hinged part 12 is hinged, and the threaded connection part 10 is arranged on The free ends of the first hinged part 11 and the second hinged 12, this kind of movable mechanical carriage can be adjusted to any angle, and then the screw 13 and the nut 14 as the twisted shaft can be locked, which can be used for fixing such as The right angle connection of two steel plates A and B shown in Figure 7, the obtuse angle connection of two steel plates A and B shown in Figure 8, the acute angle connection of two steel plates A and B shown in Figure 9, etc., have a wider range of applications .

The fixing of the magnetic horse board and the welded steel plate of the present invention completely depends on the magnetic force generated by the permanent magnet sucker, without the cooperation of other auxiliary equipment, and a single person can directly use both hands to install and remove, which is flexible and convenient, thereby improving the work efficiency of steel plate assembly in the construction process , because there is no welding, there is no trace on the surface of the base metal, and it does not have any impact on the base metal, so no treatment is required, which can reduce the workload of grinding during the construction process, reduce production costs and labor intensity, and have a high operating safety factor. There is no safety hazard, and it is suitable for fixing different connection forms of different parts such as butt joints and fillet joints of steel plates in tailor welding of steel plates.
