Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a multi-head welding frame which is easy to turn over. Background Art

[0002] Welding, also known as fusion welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. The seam formed by welding that connects two connected bodies is called a weld.

[0003] In mechanical processing, parts are often connected by welding to form an overall structure. In order to ensure the structural strength, some parts need to be welded on both the front and back sides after docking, such as the rear hook of a garbage truck, a rectangular frame, etc. When welding, the welded parts are assembled and docked according to the shape of the product and then welded on the front side. After welding, the welded product is turned over and welded on the back side.

[0004] In the prior art, front and back welding is usually performed directly on the ground or on a bracket, and the parts are flipped manually. The flipping process wastes manpower and material resources and is dangerous. If the welding is performed in a process-based manner on a production line, large machinery is required for the process-based flipping of parts, and the processing efficiency is low. If multiple groups of welding heads can be arrayed on a welding rack and the welding heads can be flipped automatically, the top and bottom surfaces of the welding rack only need to push the parts to be welded in a process-based manner, and the welding heads can be flipped automatically. This achieves a time-saving and labor-saving flip welding effect.

[0005] In view of this, it is urgent to design a multi-head welding frame that is easy to flip. By installing a rotating shaft on the welding frame, the rotating shaft drives the entire welding frame to flip in the circumferential direction, thereby driving the welding head to flip in the circumferential direction. At the same time, a rotating support shaft is installed on the welding frame, and the rotating support shaft drives the single-side welding head to rotate in the circumferential direction, so that simultaneous and synchronous bidirectional welding can be achieved. The device has a simple structure, can be installed with multiple groups of welding heads, and has a high degree of automation and process. Utility Model Content
