Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding, specifically to an auxiliary device for right-angle welding of sheet metal. Background Technology
[0002] Currently, plate welding or pipe welding is usually achieved through manual alignment. Due to unavoidable human error, the positional accuracy of the two welded parts is difficult to guarantee, resulting in poor weld quality. Therefore, the quality of the finished product and the process quality welded using the above method are difficult to guarantee.
[0003] Chinese patent number discloses a portable magnetic welding bracket. The bracket has two mutually perpendicular supports, each with a groove on its contact surface. A permanent magnet and an armature are fixed within the groove, with the armatures parallel to each other and secured to the permanent magnet using unsaturated resin adhesive. The two armatures protrude from the contact surface, ensuring parallelism of their guide surfaces and perpendicularity to the guide surface of the armature on the other support. A handle is connected to the end of each support. The permanent magnet can be made of ferrite, and the bracket material should preferably be a non-magnetic material such as aluminum alloy. The distance between the two armatures can be adjusted before fixing, and 3 to 4 armatures can be installed as needed.
[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution:
[0005] The device uses permanent magnets to attract sheet metal. When removing sheet metal, it is very laborious to remove the sheet metal from the permanent magnets.
[0006] Therefore, providing a sheet metal right-angle welding auxiliary device that can freely control the presence or absence of magnetism to facilitate the removal of sheet metal is a problem that this utility model urgently needs to solve. Utility Model Content
[0007] To address the aforementioned technical problems, the purpose of this invention is to overcome the limitations of existing devices that directly use permanent magnets to attract sheet metal. When removing the sheet metal, it is extremely laborious to remove it from the permanent magnet. Therefore, this invention provides a sheet metal right-angle welding auxiliary device that allows for free control of the magnet's magnetism, facilitating the removal of sheet metal.
[0008] To achieve the above objectives, this utility model provides an auxiliary device for right-angle welding of sheet metal. The device includes an auxiliary frame, a magnetic adsorption mechanism, and an adjustment mechanism. Magnetic adsorption mechanisms are respectively arranged inside the auxiliary frame on opposite sides. The adjustment mechanism is used to adjust the presence or absence of magnetism in the magnetic adsorption mechanisms. The magnetic adsorption mechanism includes a first iron block, a first magnet, a rotating housing, a second iron block, and a second magnet assembly. First iron blocks are respectively arranged opposite to the first magnet on opposite sides. The rotating housing is rotatably disposed on one side of the first magnet. The second magnet assembly is disposed inside the rotating housing, with second iron blocks attached to its opposite sides and the side furthest from the first magnet. The magnetic field strength of the second magnet assembly is greater than that of the first magnet. The adjustment mechanism is used to drive the rotating housing to rotate, thereby changing the magnetic field distribution of the second magnet assembly.

[0013] Preferably, the auxiliary frame is provided with a metal protective layer on its outer side.
[0014] Preferably, the outer edge of the metal protective layer is sealed with resin.
[0015] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This application uses an adjustment mechanism to drive the rotating housing to rotate, thereby changing the magnetic field distribution of the second magnet assembly, thus causing the magnetic poles of the second magnet assembly to be the same or opposite to the magnetic poles of the first magnet; when the magnetic poles are opposite, the magnetic field distribution forms a closed circuit, and at this time it appears to have no magnetism; when the magnetic poles are the same, the magnetic field distribution will be conducted along the iron block to the outside of the first magnet, and it appears to have magnetism; the rotating housing should be as thin as possible to facilitate the conduction of magnetic force; when the rotating housing drives the second magnet assembly to rotate beyond a certain angle, the attraction or repulsion between the first magnet and the second magnet assembly will automatically adjust the magnetic field distribution, so there is no need to limit the rotating housing; thus, the presence or absence of magnetism of the magnet can be controlled.

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0027] Reference Figures 1-4A sheet metal right-angle welding auxiliary device includes: an auxiliary frame 1, a magnetic adsorption mechanism 2, and an adjustment mechanism 3. The auxiliary frame 1 has magnetic adsorption mechanisms 2 arranged on opposite sides. The adjustment mechanism 3 is used to adjust the presence or absence of magnetism in the magnetic adsorption mechanisms 2. The magnetic adsorption mechanism 2 includes: a first iron block 201, a first magnet 202, a rotating housing 203, a second iron block 204, and a second magnet assembly 205. The first magnet 202 has first iron blocks 201 arranged opposite each other on opposite sides. The rotating housing 203 is rotatably disposed on one side of the first magnet 202. The second magnet assembly 205 is disposed inside the rotating housing 203, and second iron blocks 204 are attached to its opposite sides and the side away from the first magnet 202. The magnetic field strength of the second magnet assembly 205 is greater than that of the first magnet 202. The adjustment mechanism 3 is used to drive the rotating housing 203 to rotate, thereby changing the magnetic field distribution of the second magnet assembly 205.
[0028] This application uses an adjustment mechanism 3 to drive the rotating housing 203 to rotate, thereby changing the magnetic field distribution of the second magnet assembly 205, resulting in the magnetic poles of the second magnet assembly 205 being the same as or opposite to the magnetic poles of the first magnet 202. When the magnetic poles are opposite, the magnetic field distribution forms a closed circuit, and at this time, it appears to have no magnetism. When the magnetic poles are the same, the magnetic field distribution will be conducted along the iron block to the outside of the first magnet 202, and it will appear to have magnetism. The rotating housing 203 is designed to be as thin as possible to facilitate the conduction of magnetic force. When the rotating housing 203 drives the second magnet assembly 205 to rotate beyond a certain angle, the attraction or repulsion between the first magnet 202 and the second magnet assembly 205 will automatically adjust the magnetic field distribution, so there is no need to limit the rotating housing 203; thus, the presence or absence of magnetism can be controlled.
[0029] Reference Figure 4 The second magnet assembly 205 includes at least two first magnets 202 arranged with the same magnetic pole along the axis of the rotating housing 203.
[0030] This application uses this design to ensure that the magnetic field strength of the second magnet assembly 205 is greater than that of the first magnet 202, and it can be completed by producing or purchasing at least three first magnets 202 without having to produce or purchase two different magnets.
[0031] Reference Figure 4 The rotating housing 203 is provided with a limiting ring block 20301 on the side near the first iron block 201, and the first iron block 201 is provided with a limiting ring groove 20101 that is adapted to the limiting ring block 20301 on the side near the rotating housing 203.
[0032] This application uses this design to ensure that the rotating housing 203 is rotatably assembled in the limiting ring groove 20101 by the limiting ring block 20301 and will not separate.
[0033] Reference Figure 2 The adjustment mechanism 3 includes a transmission bevel gear 301, a drive bevel gear 302, and a knob 303. The transmission bevel gear 301 is coaxially disposed at the end of the rotating housing 203 away from the first magnet 202. The knob 303 is rotatably disposed on the auxiliary frame 1, and its output end is coaxially disposed with a drive bevel gear 302 that meshes with the transmission bevel gear 301.
[0034] This application uses a knob 303 to rotate a drive bevel gear 302, which in turn rotates a transmission bevel gear 301, thereby changing the magnetic field distribution of the second magnet assembly 205 by rotating the housing 203. When the rotating housing 203 drives the second magnet assembly 205 to rotate beyond a certain angle, the attraction or repulsion between the first magnet 202 and the second magnet assembly 205 will automatically adjust the magnetic field distribution, so there is no need to limit the drive bevel gear 302 and the knob 303.
[0035] Reference Figure 2 The knob 303 is surrounded by anti-slip texture.
[0036] This application incorporates anti-slip textures to facilitate user rotation of knob 303.
[0037] Reference Figure 1 The auxiliary frame 1 is provided with a metal protective layer 4 on its outer side.
[0038] This application protects the magnetic adsorption mechanism 2 from external environmental influences by setting a metal protective layer 4, thereby extending its service life.
[0039] Reference Figure 1 The outer edge of the metal protective layer 4 is wrapped with resin sealing 5.
[0040] This application uses resin edge sealing 5 to prevent the edges of the metal protective layer 4 from scratching the sheet metal and people.
[0041] When in use, the device provided by this utility model drives the rotating housing 203 to rotate via the adjusting mechanism 3, thereby changing the magnetic field distribution of the second magnet assembly 205. This causes the magnetic poles of the second magnet assembly 205 to be the same as or opposite to the magnetic poles of the first magnet 202. When the magnetic poles are opposite, the magnetic field distribution forms a closed circuit, and at this time, it appears to have no magnetism. When the magnetic poles are the same, the magnetic field distribution will be conducted along the iron block to the outside of the first magnet 202, and it appears to have magnetism. The rotating housing 203 should be made as thin as possible to facilitate the conduction of magnetic force, thereby achieving control over the presence or absence of magnetism.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0044] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
