Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal welding, in particular to a sheet metal box welding device. Background Art

[0002] Products processed by sheet metal technology are called sheet metal parts. Box sheet metal parts are sheet metal parts shaped like metal boxes. During the processing and forming process of box sheet metal parts, four frames generally need to be butt-welded to form a box structure. Therefore, a sheet metal box welding device is proposed.

[0003] In the existing technology, a welding device for processing box sheet metal parts is proposed with the publication number: CN218426533U, which includes a welding platform and a clamping assembly. The welding platform is provided with a clamping assembly, and the clamping assembly includes a fixing plate, an electric push rod, a linkage plate, a mounting block, a clamping rod and an adjustment unit. When fixing the frame, this scheme can manually place the frame between the clamping rods, and then adjust the distance between the clamping rods through the adjustment unit, so that the distance between the clamping rods adapts to the thickness of the frame and clamps it, which changes the clamping method of the traditional clamping parts and avoids blocking the welding parts. In addition, by arranging two sets of clamping rods on each frame, the clamping effect can be enhanced.

[0004] In order to solve the problem that the clamping parts for clamping and fixing the frame are easy to block the welding parts of the frame during actual use, and cannot be adjusted according to the thickness of the frame, resulting in poor clamping effect, the prior art adopts an adjustable clamping rod to deal with it. However, there is a lack of a buffer unit during the clamping process, resulting in excessive clamping force, causing damage and bending to the sheet metal parts of the box, affecting the appearance, and requiring rework, delaying the processing progress, which in turn leads to the problem of reduced utilization efficiency of the welding device. Utility Model Content

[0005] The purpose of the utility model is to provide a sheet metal box welding device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0011] A further improvement of the technical solution of the utility model is that a support plate is fixedly installed at the bottom of the support base, a positioning screw is connected to the internal thread of the support plate, and a shock-absorbing plate is fixedly installed at one end of the positioning screw.

[0012] A further improvement of the technical solution of the utility model is that a lifting slide is slidably installed on the surface of the electric slide rail, a mounting plate is fixedly installed on the front side surface of the lifting slide, electric push rods are fixedly installed on both side surfaces of the mounting plate, a limiting plate is installed at one end of the electric push rod, and a welding head is fixedly installed on the bottom of the limiting plate.

[0013] A further improvement of the technical solution of the utility model is that the clamping unit includes an adjusting handle arranged on one side surface of the welding workbench, a bidirectional threaded rod is fixedly connected inside the adjusting handle, and the bidirectional threaded rod is rotatably installed inside the welding workbench.

[0014] A further improvement of the technical solution of the utility model is that a slider is movably installed on the outer surface of the bidirectional threaded rod, the slider is slidably installed inside the slide groove, a clamping positioning seat is fixedly installed on the upper surface of the slider, a clamping plate is fixedly installed on the front side surface of the clamping positioning seat, and an anti-slip strip is fixedly installed on the front side surface of the clamping plate.

[0018] 2. The utility model provides a sheet metal box welding device. Through the design of the arc-shaped elastic plate, when the clamping plate is clamped, the clamping force exerted on the surface forms a pressure on the arc-shaped elastic plate, which then causes bending and elastic deformation.

At the same time, the buffer sandwich plate subjected to the pressure absorbs the force, and a rubber buffer pad is used to improve the buffering effect. By buffering the clamping force, bending of the sheet metal parts that affects the appearance is avoided, thereby improving the utilization efficiency of the welding device.
