[0029] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0031] Please refer to Figure 1 The present application provides a technical scheme: a welding positioning structure for conveniently fixing sheet metal parts, comprising:

[0032] A bottom plate 1, wherein a first gap 2 is arranged in the middle part;

[0033] A lower hanging support plate 4 is arranged at the bottom of the bottom plate 1, and a second gap 3 is arranged on the upper part of the lower hanging support plate 4;

[0034] A positioning plate 5 is positioned in the second gap 3;

[0035] A plurality of air cylinders 6 are arranged on the top surface of the bottom plate 1 and the positioning plate 5, and the output shafts of the air cylinders 6 are rotatably driven to abut and press the swing block 7;

[0036] A pneumatic valve 8 is arranged at the edge of the bottom plate 1.

[0037] The air cylinder 6 is an ACK air cylinder, which stably rotates and drives the swing block 7 to ensure that the sheet metal part is fully pressed and positioned.

[0038] The swing block 7 includes a swing plate abutting the output shaft of the air cylinder 6 and a cylindrical pressing block positioned at the other end of the swing plate, thereby ensuring the positioning strength of the sheet metal part.

[0039] The bottom plate 1 is further provided with a quick clamp 9. Therefore, before the swing block 7 positions the sheet metal part, the quick clamp 9 can be used to pre-position the sheet metal part, thereby achieving sufficient positioning of the top of the stepped sheet metal part through the double positioning mode. The quick clamp 9 is a conventional positioning component, which can be lifted or pressed by the handle, and the pressing rod can be lifted or pressed through the hinged structure, thereby quickly switching the active and positioning state of the sheet metal part. The specific structure is not described here.

[0040] The lower hanging support plate 4 is U-shaped or L-shaped structure, thereby ensuring the positioning strength of the positioning plate 5, while the bottom of the stepped sheet metal part can be accommodated, and the surface of the sheet metal part is fully supported by the side wall of the second gap 3 and the top surface of the positioning plate 5, thereby improving the positioning strength of the sheet metal part.

[0041] The end of the lower hanging support plate 4 is provided with an assembly hole 10, which is positioned by the screw hole on the limiting plate at the bottom of the bottom plate 1. The assembly hole 10 is a waist-shaped hole. The adjustable arrangement of the lower hanging support plate 4 through the waist-shaped assembly hole 10 can adjust the hanging height of the lower hanging support plate 4 to adapt to the positioning needs of sheet metal parts of different sizes at the bottom.

[0042] The working principle of the welding positioning structure for conveniently fixing the sheet metal part of the embodiment includes that the welding positioning device is used for positioning the stepped sheet metal part. In use, the sheet metal part is placed on the bottom plate 1, the bottom of which is extended downward by the first gap 2 and abuts on the second gap 3 and the positioning plate 5, thereby ensuring that the sheet metal part is fully attached to the device; then, the sheet metal part is preliminarily positioned by the quick clamp 9, the pneumatic valve 8 is actuated, and the pneumatic cylinder 6 is used for secondary positioning, that is, the positioning of the sheet metal part is completed, and welding operation can be performed. Before the positioning of the sheet metal part, the height of the lower hanging support plate 4 can be adjusted based on the size of the sheet metal part, and the waist-shaped assembly hole 10 on the lower hanging support plate 4 is positioned with the limiting plate by a bolt, so as to facilitate the positioning and welding of sheet metal parts of different sizes. The device has high positioning strength for the stepped sheet metal part, and the sheet metal part is not deformed after positioning.

[0043] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
