[0002] An engineering bucket is a bucket installed on construction machinery and is categorized by working mode as either a backhoe or front shovel. Backhoe buckets are commonly used. Buckets are structural components, typically consisting of welded components such as a tooth adapter plate, base plate, side plates, wall panels, lug plates, back plates, bucket lug plates, bucket lug sleeves, bucket teeth, tooth adapters, guard plates, or bucket angles. Therefore, welding is the most critical manufacturing process for buckets, and the quality of welding directly affects the bucket's structural strength and service life. Existing welding auxiliary tooling for engineering buckets can only securely position the bucket body on a horizontal platform and cannot adjust the bucket's position during welding. This significantly impacts the efficiency of bucket welding and fails to meet specific production needs. Summary of the Invention
