Description

Technical Field

[0001] This utility model relates to the field of cabinet panel welding technology, and in particular to a welding fixture for the production of metal cabinet panels. Background Technology

[0002] Metal cabinet panel reinforcing ribs (as attached) Figure 5 For welding work (as shown), it is essential to first ensure that the surfaces of the metal cabinet panel and reinforcing ribs are clean and free of impurities. Appropriate welding parameters should be determined based on the metal material, panel thickness, and reinforcing rib specifications. Due to the thinness of the metal cabinet panel and reinforcing ribs, spot welding equipment is often used. Strict adherence to standard operating procedures is crucial to ensure a firm weld between the reinforcing ribs and the metal cabinet panel, thereby effectively enhancing the structural strength and stability of the metal cabinet panel. However, when workers use handheld spot welding guns to weld the reinforcing ribs, the lack of specialized welding fixtures often leads to haphazard selection of spot welding positions based on experience, making it difficult to guarantee accurate spot welding positions and consistent finished product quality.

DETAILED DESCRIPTION

[0023] The utility model will be further explained in detail in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only a part of the embodiments of the utility model, but not all the embodiments.

[0024] The specific embodiments of the welding jig for metal cabinet plate production provided by the utility model are as follows:

[0025] Please refer to Figure 1-6Welding reinforcing ribs 11 on the side of the metal cabinet plate 10 can improve the strength of the cabinet plate 10 and avoid the deformation of the cabinet plate 10; however, the position of the reinforcing ribs 11 and the spot welding position are difficult to directly determine, and the consistency of the position can be hardly ensured only by the experience of workers. Therefore, a welding jig is designed, which comprises a rectangular frame 1, a plurality of parallel reference strips 2 and a plurality of positioning members 3.

[0026] The rectangular frame 1 is wrapped around the outer ring side of the cabinet plate 10. Specifically, the lower side of each corner of the rectangular frame 1 is provided with an L-shaped extension 5 which is integrally connected with the rectangular frame 1. The extension 5 is perpendicular to the lower side of the rectangular frame 1, and the inner side of the extension 5 is downwardly extended as the inner side of each corner of the rectangular frame 1, so that the inner side of the extension 5 can be wrapped around the two outer sides of each corner of the cabinet plate 10.

[0027] The two ends of each reference strip 2 are connected with two opposite side frames of the rectangular frame 1 and correspond to the upper side of each reinforcing rib 11 of the cabinet plate 10. The reference strip 2 is in the shape of a strip plate, and the reference strip 2 is located on the upper side of the rectangular frame 1. The number of the reference strips 2 is the same as and corresponds to the number of the reinforcing ribs 11 to be welded.

[0028] In order to adapt to the welding of reinforcing ribs 11 with different numbers and positions, the connection position of the reference strip 2 with the rectangular frame 1 can be changed. Specifically, each of the two opposite side frames of the rectangular frame 1 is provided with a first strip hole 6, and the number of the first strip holes 6 is two and they are parallel to each other. The end of each reference strip 2 is provided with a first bolt 7, and the end of the reference strip 2 is provided with a through hole through which the first bolt 7 passes. The first bolt 7 also passes through the first strip hole 6, and the first bolt 7 is connected with a nut.

[0029] When the nut is tightened, the nut and the first bolt 7 clamp the end of the reference strip 2 at the side frame of the rectangular frame 1. When welding reinforcing ribs 11 in the same batch, the position of the reference strip 2 is determined according to the number and position of the reinforcing ribs 11, and then the position of the reference strip 2 is fixed by using the first bolt 7 and the nut. After that, the position of the reference strip 2 does not need to be changed. When welding reinforcing ribs 11 in another batch, the position of the reference strip 2 is changed again.

[0030] The middle part of each positioning member 3 is connected with the reference strip 2, and a plurality of positioning members 3 are arranged along the reference strip 2 according to the required spot welding positions of the reinforcing ribs 11.

[0031] In order to adapt to different spot welding positions and the number of spot welding points of the reinforcing ribs 11, the position of the positioning member 3 along the reference strip 2 can be adjusted. Specifically, each reference strip 2 is provided with a second strip hole 8, the middle part of each positioning member 3 is provided with a second bolt 9, the middle part of the positioning member 3 is located on the upper side of the reference strip 2, the middle part of the positioning member 3 is provided with a through hole through which the second bolt 9 passes, the second bolt 9 also passes through the second strip hole 8, and the second bolt 9 is connected with a nut.

[0032] The nut on the second bolt 9 is screwed, so that the position of the positioning member 3 on the reference strip 2 is fixed. When the number of spot welding points needs to be increased or reduced, the number of the positioning member 3 is increased or reduced, and the position of the positioning member 3 is adjusted.

[0033] The positioning member 3 is provided with a notch 4 for the spot welding gun to pass through at both ends. Specifically, the positioning member 3 comprises an inverted U-shaped portion 31, and the lower ends of the two side edges of the inverted U-shaped portion 31 are connected to horizontal bent portions 32, and the notch 4 extends from the bent portion 32 to the side edge of the inverted U-shaped portion 31.

[0034] The two side edges of the inverted U-shaped portion 31 are attached to the two sides of the reinforcing rib 11, so that the positioning member 3 can position the reinforcing rib 11 on the side of the cabinet plate 10, and the notch 4 can indicate the spot welding position. Thus, the accuracy and consistency of the position of the reinforcing rib 11 and the spot welding position are ensured, and the product quality is ensured.

[0035] Welding process: place the cabinet plate 10 to be welded on the copper plate 12 on the workbench, and the copper plate 12 serves as the welding electrode;

[0036] Place each reinforcing rib 11 on the cabinet plate 10;

[0037] Place the device on the cabinet plate 10 with reinforcing ribs 11, and adjust the position of the reinforcing rib 11 during the placement process, so that the reinforcing rib 11 is located between the side edges of the positioning member 3; the positioning member 3 limits the position of the reinforcing rib 11, so that the reinforcing rib 11 is not misaligned during the welding process;

[0038] Use the spot welding gun corresponding to the notch 4 to accurately weld each spot;

[0039] After completion, separate the welding fixture from the welded product.

[0040] Finally, it should be noted that the above only describes preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications to the technical solutions described in the foregoing embodiments without creative labor, or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
