Description

Technical Field

[0001] The utility model relates to the technical field of workpiece welding, in particular to a large-scale steel structure workpiece welding displacement device. Background Art

[0002] Large steel structure workpieces are an important structural form widely used in modern buildings, bridges, industrial facilities and other fields. They use steel as the main material and form a strong and stable structure through welding, bolting and other methods. During welding, the workpiece can only be welded in the same position, which makes it impossible to perform positional welding on the steel structure workpiece, resulting in low welding efficiency. Therefore, it is necessary to displace the workpiece during welding.

[0003] A Chinese patent discloses a large workpiece welding displacement device (Announcement No. CN115178957A). The patented technology has a simple structure, ingenious design, and reasonable layout. It designs a special structure to solve the problems existing in traditional large and heavy workpiece welding operations. It consists of a fixed mechanism and an adjustable mechanism. The fixed mechanism and the adjustable mechanism can jointly clamp the target workpiece and drive the target workpiece to achieve a large-angle flip in space. Through the coordinated action with the manipulator, fast and convenient automated welding operations are achieved; at the same time, its adjustable mechanism can also change the spacing between it and the fixed mechanism, so as to be suitable for the flipping operation of workpieces of different specifications. The manufacturing process of this welding displacement device is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad.

[0004] However, most of the existing large steel workpiece positioning methods used during processing position the workpiece in one direction, resulting in poor positioning and clamping effects, affecting its stability. For example, the above-mentioned reference document uses a clamping method in one direction. In practical applications, the stability of the workpiece needs to be ensured during welding. When the workpiece is adjusted, it is easy to deviate and affect its welding work. Therefore, those skilled in the art provide a large steel structure workpiece welding displacement device to solve the problems raised in the above-mentioned background technology.
