Description

Technical Field

[0001] The invention relates to the technical field of bucket welding processing, and in particular to a bucket welding device with multi-directional adjustment. Background Art

[0002] The bucket of a scraper loader is generally composed of a cover plate, side plates, baffles, cutter plates, corner edges and side edges. The cutter plate is located in the front lower end of the bucket. Holes are generally reserved on the cutter plate for installing bucket teeth and auxiliary cutter plates. The cover plate, side plates and baffles of the scraper loader bucket for earthmoving projects are usually welded from low-carbon, wear-resistant and high-strength steel plates. When processing the bucket, the steel plate needs to be rolled to bend it to form a cover plate. After the plate is processed, the components are welded and assembled.

[0003] During the existing bucket welding process, due to the bending of the cladding plate, the two ends of the threaded telescopic rod need to be welded to the inner curved surface of the cladding plate during the combined welding to fix the curvature of the cladding plate to prevent the elastic bending of the cladding plate from affecting the operation during the side plate welding. When using the threaded telescopic rod, the welding point between the threaded telescopic rod and the inner curved surface of the cladding plate needs to be broken after the side plate is welded. The process of using the threaded telescopic rod will reduce the efficiency of the bucket welding process.
