Technical Field

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

[0002] Welding equipment consists of a base, a shell, a cabinet door, a body, a welding head and a placement table. It is used to weld sheet metal parts and is more common in daily life.

[0003] Existing technologies include the utility model with publication number CN221639995U, which discloses an automatic welding device for sheet metal parts. The patent adopts a welding table, and a top table is arranged directly above the welding table. A horizontal linear slide is installed on the bottom of the top table, and a clamping welding mechanism is installed on the sliding end of the horizontal linear slide. Two side positioning clamps are distributed horizontally and parallel on the top of the top table, and a clamping drive mechanism for synchronously driving the two side positioning clamps is arranged inside the left end of the welding table, which solves a series of shortcomings of existing sheet metal welding equipment in terms of accuracy, flexibility, degree of automation and consistency.

[0004] In daily work, it is found that in the process of welding sheet metal parts, the fixtures in the existing technology can only fix and weld a single type of sheet metal part, resulting in the inability to fix special-shaped sheet metal parts or other types of sheet metal parts, which requires operators to hold the welding parts for processing. However, the high temperature generated during processing can easily burn the operators.

[0005] Therefore, it is necessary to provide a new welding equipment for sheet metal parts to solve the above technical problems. Utility Model Content

[0009] Preferably, a limiting rod is fixedly connected to the interior of the connecting rail, and the limiting rod is slidably connected to the sliding rod.

[0010] The effects achieved by the above components are: the limiting rod can limit the sliding rod, thereby preventing the sliding rod from deflecting when moving, and improving the sliding stability of the sliding rod.

[0011] Preferably, the two positioning plates are fixedly connected to one side thereof close to each other with an anti-slip pad, and the anti-slip pad is a rubber pad.

[0012] The effect achieved by the above components is that the anti-slip pad can increase the friction between the positioning plate and the sheet metal part, thereby preventing the positioning plate from sliding when clamping the sheet metal part.

[0013] Preferably, the guide rail is made of stainless steel, and is connected to the placement table by welding.

[0014] Preferably, an adjustment structure is provided inside the shell, and the adjustment structure includes a screw, which is fixedly connected to the shell, and the inner wall of the screw is slidably connected to a round rod, and the upper end of the round rod is fixedly connected to the placement table, and the arc surface of the screw is threadedly connected to a threaded ring, and the inner wall of the threaded ring is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to a plurality of auxiliary rods, and the upper end of the auxiliary rod is fixedly connected to the placement table.

[0015] The effect achieved by the above components is: when the height of the placement table needs to be adjusted, the threaded ring is rotated to move, the threaded ring moves on the screw, the threaded ring drives the slide to move, the slide drives the auxiliary rod to move, the auxiliary rod drives the placement table to move up and down, and the placement table drives the round rod to slide on the inner wall of the screw, thereby adjusting the height of the placement table.

[0016] Preferably, a protective sleeve is fixedly connected to the arc surface of the threaded ring, and the cross-section of the protective sleeve is circular.

[0017] The effects achieved by the above components are: the protective sleeve can protect the threaded ring and prevent the threaded ring from excessive wear during use.

[0018] Preferably, the arc surface of the protective sleeve is provided with a plurality of notches, and the plurality of notches are evenly distributed on the protective sleeve.

[0019] The effect achieved by the above components is that the notch can increase the friction between the hand and the protective sleeve, thereby preventing slippage when the threaded ring is rotated.

[0020] Compared with the related art, the welding equipment for sheet metal parts provided by the present invention has the following beneficial effects:

[0021] The utility model provides a welding device for sheet metal parts. By setting a fixing structure, the sheet metal parts can be conveniently fixed, avoiding the problem that the clamps in the prior art can only fix and weld a single type of sheet metal part, resulting in the inability to fix special-shaped sheet metal parts or other types of sheet metal parts, which requires the operator to hold the welding process, but the high temperature generated during processing can easily burn the operator. The present solution can conveniently clamp and fix sheet metal parts of different types and shapes.

[0022] By setting up the adjustment structure, the height of the placement table can be easily adjusted to avoid the effect of being unable to grasp the distance between the sheet metal and the welding head. BRIEF DESCRIPTION OF THE DRAWINGS
