Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an automatic welding device. Background Art

[0002] In the prior art, for the welding of the body sheet metal parts of new energy vehicles, simple jigs are used for clamping and then manual welding is carried out. This welding method not only has low efficiency but also cannot guarantee the welding quality. Obviously, manual welding is not suitable for the modern production mode.

[0003] For example, the Chinese utility model patent (CN220178561 U) discloses an automatic welding device for automotive metal components, which records: "Due to the technical means of using a linearly moving welding torch, rotating the automotive metal component, and moving the clamping mechanism, when welding a relatively large automotive metal component, the automotive metal component can be placed on the placement table, and then the first motor is started. The first motor drives the circular plate to rotate, the circular plate drives the placement table to rotate, and the placement table drives the automotive metal component to rotate, moving the position to be welded to be in the same straight line as the welding torch. Then the second motor is started. The second motor drives the bidirectional lead screw to rotate, the bidirectional lead screw drives the sliding mechanisms at both ends to approach each other, and the two sliding mechanisms drive the clamping mechanisms to approach each other until the automotive metal component is firmly clamped. Then the first electric telescopic rod is started to lower the welding torch, and then the second electric telescopic rod is used to horizontally move the welding torch as needed for comprehensive welding", and also records: "Most of the existing automatic welding devices have low versatility and cannot clamp and fix relatively large automotive metal components for welding. If clamping cannot be carried out, the automotive metal component may shift during welding, resulting in welding failure and economic losses. And when welding a relatively large automotive metal component, the welding point needs to be moved to ensure comprehensive welding and quality reliability" technical problems.

[0004] In summary, the following technical problems exist in the prior art: When the automatic welding device in the above patent welds automotive parts, since the position of the placement table is always vertically upward, the welding torch can only weld the top surface of the automotive parts during welding. When welding the side surface of the automotive parts, additional tools are needed for turning over, and the clamping position cannot be changed when clamping the automotive parts. It is difficult to clamp irregular, large, and high parts. Therefore, this application proposes an automatic welding device to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Utility Model
