Abstract
Description
Technical Field
[0001] The utility model mainly relates to a sheet metal assembly fixture.
Background Art
[0002] A sheet metal assembly fixture is an essential tool in the sheet metal assembly process. However, for existing fixtures, when dealing with sheet metal fittings of different shapes and sizes, they often shift, resulting in unstable assembly, low efficiency, and it is difficult to fix sheet metal fittings of different specifications. Especially when two sheet metal parts need to be screwed together, due to the shift, it is difficult to align the holes, which slows down the construction period and requires workers to repeatedly fix them, wasting time and effort and affecting the progress of the workers' projects. Therefore, to solve the problem that the holes are difficult to align due to the easy shift during the screwing of sheet metal parts, we have developed a general sheet metal fixture structure.

A limiting cone strip, a spring, and a height adjusting screw are placed in the screw access hole. The height adjusting screw is screwed into the adjusting thread from the bottom of the screw access hole. The limiting cone strip and the spring are placed in the screw access hole from the top of the screw access hole, and the spring is located between the limiting cone strips. The limiting cone strip extends out of the screw access hole by the cooperation of the spring and the height adjusting screw.
[0006] Preferably, the bottom plate is provided with a plurality of access positions, and the positioning seat is fixed on the access positions by screws to be assembled on the bottom plate.

[0015] The technical solutions and their beneficial effects of the utility model will be made clearer and more definite by further describing the specific embodiments of the utility model in conjunction with the drawings of the specification. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model and should not be construed as limiting the utility model.
[0016] The preferred embodiment provided by the utility model: As Figure 1 shown in Figure 2 a sheet metal assembly fixture, which includes a bottom plate 1 and a positioning seat 2, and the bottom plate 1 and the positioning seat 2 are of a split assembly structure;
[0017] The positioning seat 2 is provided with screw access holes 21 which penetrate through the positioning seat 2. An adjusting thread 22 is provided at the bottom of the screw access holes 21. A limiting cone strip 3, a spring 4 and a height adjusting screw 5 are placed in the screw access holes 21. The height adjusting screw 5 is screwed onto the adjusting thread 22 from the bottom of the screw access holes 21. The limiting cone strip 3 and the spring 4 are placed into the screw access holes 21 from the top of the screw access holes 21, and the spring 4 is located between the limiting cone strips 3. The limiting cone strip 3 extends out of the screw access holes 21 under the cooperation of the spring 4 and the height adjusting screw 5.
[0018] A number of access positions 11 are arranged on the bottom plate 1. The positioning seat 2 is fixed on the access positions 11 by screws to be assembled on the bottom plate 1. The positioning seat 2 is provided with a concave position 23 for clamping a workpiece. Elastic pressing members 6 are respectively arranged on both sides of the concave position 23, and the elastic pressing members 6 on both sides are arranged oppositely. The elastic pressing member 6 includes a spring 61 and a pressing block 62. One end of the spring 61 is fixed on the concave position 23, and the other end is connected to the pressing block 62. The pressing block 62 moves in the concave position 23 under the action of the spring 61.
[0019] Sheet metal is a comprehensive cold working process for metal sheets, including cutting, punching, folding, welding, riveting, splicing, forming, etc. Sheet metal assembly is to assemble a series of sheet metal profiles together to make it have better use value. Sheet metal has the characteristics of low cost and good mass production performance, and has been widely used in the field of furniture decoration.
[0020] To solve the problem that the locking between sheet metal parts is prone to deviation, making it difficult to align the holes, the present utility model proposes a sheet metal assembly fixture, which includes a bottom plate 1 and a positioning seat 2. The bottom plate 1 and the positioning seat 2 are of a split assembly structure, and the position of the positioning seat 2 can be adjusted according to the sheet metal structure to be processed, with stronger versatility. To further improve the accuracy of sheet metal positioning, the positioning seat 2 is provided with a screw access hole 21, and the bottom of the screw access hole 21 is provided with an adjusting thread 22. The height adjusting screw 5 is screwed into the adjusting thread 22 to support the spring 4 and the limiting cone strip 3. By rotating the height adjusting screw 5, the insertion amount of the height adjusting screw 5 can be adjusted, thereby controlling the length of the limiting cone strip 3 extending out of the screw access hole 21. To facilitate the rotation of the height adjusting screw 5, the bottom plate 1 is provided with a through hole 12, and the position of the through hole corresponds to the position of the screw access hole 21. When assembling the sheet metals, the sheet metal strip is embedded in the concave position 23 of the positioning seat 2, and the limiting cone strip 3 is pushed by the spring 4 to extend into the connection hole of the sheet metal strip, and the sheet metal strip is limited in the vertical position by the limiting cone strip 3. At the same time, the sheet metal part embedded in the concave position 23 is clamped by the elastic pressing parts 6 on both sides in the concave position 23, further limiting the horizontal position of the sheet metal part. By restricting the sheet metal part in both the horizontal and vertical positions, displacement basically does not occur. At this time, the screw can be passed through the sheet metal part. The connection hole of the sheet metal part is usually a screw hole. When the screw passes through the connection hole of the sheet metal part, the limiting cone strip 3 is gradually pressed down by the screw in the connection hole and retracts into the screw access hole 21. Therefore, the limiting cone strip 3 does not affect the locking between the sheet metal parts. After the sheet metal parts are locked, the positioning seat 2 is removed, and the limiting cone strip 3 will extend out of the screw access hole 21 again under the action of the spring 4, facilitating the next assembly process.
