Description

Technical Field

[0001] The utility model belongs to the technical field of welding auxiliary devices, and particularly relates to an auxiliary welding device for sheet metal parts. Background Art

[0002] During the process of sheet metal production, it is often necessary to weld and assemble two or more sheet metal parts. As Figure 1 shown, when the first sheet metal part 10 and the second sheet metal part 20 are spliced, it is necessary to straighten the second sheet metal part 20, maintain its current position, and then weld to form a welding position 30 to realize the connection between the two. Currently, welding is often carried out by workers using pliers or holding one of the sheet metal parts by hand to weld the connection part. This often requires the worker to free one hand to hold the second sheet metal part 20 and hold the welding gun with the other hand. On the one hand, the operation is inconvenient, and on the other hand, it often causes problems such as burns to the other hand. Summary of the Invention

[0003] The purpose of the utility model is to provide an auxiliary welding device for sheet metal parts, which is intended to facilitate the welding and assembly of two sheet metal parts.

[0004] To solve the above technical problems, the purpose of the utility model is realized as follows:

[0005] An auxiliary welding device for sheet metal parts includes an auxiliary welding component, which includes a magnetic base, a support column, a first fixing plate, a second fixing plate, an adjusting and pressing member, and a first strong magnet; the support column is connected to the magnetic base, and the first fixing plate and the second fixing plate are fixedly arranged in parallel at one end of the support column away from the magnetic base; the adjusting and pressing member includes a threaded rod, the threaded rod is perpendicular to the second fixing plate and is threadedly connected to the second fixing plate; rotating the threaded rod can change the distance between the head end of the threaded rod and the first fixing plate.

[0006] On the basis of the above solution and as a preferred solution of the above solution: a groove is opened at the bottom of the magnetic base, and a second strong magnet is fixedly embedded in the groove.

[0007] On the basis of the above solution and as a preferred solution of the above solution: the bottom surface of the second strong magnet is flush with the base of the magnetic base, and an anti-slip layer is provided at its bottom.

[0008] On the basis of the above solution and as a preferred solution of the above solution: the anti-slip layer is a rubber pad.

[0009] On the basis of the above solution and as a preferred solution of the above solution: a pressing plate is arranged at one end of the threaded column close to the first fixing plate, and a rotating part is arranged at the end away from the first fixing plate.

[0010] The prominent and beneficial technical effects of the present utility model compared with the prior art are as follows: Since most sheet metal parts are made of stainless steel and are not magnetic, through the arrangement of the magnetic base and the first strong magnet, adsorption is carried out from the surface and the bottom surface of the sheet metal part by magnetic force respectively, so that the magnetic base is fixed on the surface of the sheet metal part through friction. Through the cooperation of the support column and the adjusting pressing member, the other sheet metal part is clamped by rotating the threaded rod of the adjusting pressing member, and is supported and maintained by the support column, thus replacing manual support of the other sheet metal part and maintaining the current position. Workers can perform more precise operations with both hands for welding, improving the welding quality and welding convenience, and at the same time, problems such as skin burns can be well avoided.

[0013] In the description of this application, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0014] In the description of this application, terms such as "first", "second", etc. are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features.

[0015] See details in Figure 1As shown in the figure, the present application discloses an auxiliary welding device for sheet metal parts, including an auxiliary welding assembly 40, which includes a magnetic base 41, a support column 42, a first fixing plate 43, a second fixing plate 44, an adjusting and pressing member 45, and a first strong magnet 47. By arranging the magnetic base 41 and the first strong magnet 47 in pairs, they are adsorbed from the surface and bottom surface of the first sheet metal part 10 respectively through magnetic attraction, so that the magnetic base 41 is fixed on the surface of the first sheet metal part 10 by friction. The support column 42 is connected to the magnetic base 41. Specifically, threaded holes can be machined on the magnetic base 41, and external threads are machined at the connecting end of the support column 42, and then the two are connected by threads. In addition, the first fixing plate 43 and the second fixing plate 44 are fixedly arranged in parallel at one end of the support column 42 away from the magnetic base 41, so as to form a clamping space therebetween. The adjusting and pressing member 45 includes a threaded rod 453, the threaded rod 453 is perpendicular to the second fixing plate 44 and is threadedly connected to the second fixing plate 44. Rotating the threaded rod 453 can change the distance between the head end of the threaded rod 453 and the first fixing plate 43. Specifically, a pressing plate 452 is arranged at one end of the threaded rod 453 close to the first fixing plate 43, and a rotating part 451 is arranged at the end away from the first fixing plate 43. Then, by rotating the threaded rod 453 through the rotating part 451, the pressing plate 452 can be driven to approach or move away from the first fixing plate 43, so as to clamp or release the second sheet metal part 20. After adjusting the second sheet metal part 20 to a suitable position, at this time, the second sheet metal part 20 and the first sheet metal part 10 reach a suitable connection position. Tighten the threaded rod 453 so that the pressing plate presses on the second sheet metal part 20, and then welding operations can be carried out.

[0016] Furthermore, in order to realize the magnetism of the magnetic base 41, in this embodiment, it is preferred that a groove is opened at the bottom of the magnetic base 41, and a second strong magnet 411 is fixedly embedded in the groove. And the bottom surface of the second strong magnet 411 is flush with the base of the magnetic base 41, and an anti-slip layer 412 is provided at its bottom. The setting of the anti-slip layer 412 can increase the friction with the surface of the first sheet metal part during the magnetic adsorption of the first strong magnet and the second strong magnet, thereby improving the overall stability. Among them, it is preferable that the anti-slip layer 412 is a rubber pad, which is adhered to the bottom surface of the magnetic base 41 by glue.

[0017] Thus, by using the present application to replace manual support of another sheet metal part and maintain the current position, workers can perform more precise operations with both hands for welding, improving welding quality and welding convenience, and at the same time, it can also well prevent problems such as skin burns.

[0018] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
