Description

Technical Field

[0001] This utility model belongs to the field of bucket welding and repair technology, specifically an excavator bucket welding and repair device. Background Technology

[0002] The excavator bucket is a core structural component of the excavator, welded together from parts such as the tooth base plate, bottom plate, side plates, wall plates, and lug plates. It is mainly divided into two categories: backhoe buckets and front shovel buckets. The welding quality directly affects the structural strength and service life. The manufacturing process involves material preparation, forming, and welding, requiring equipment such as CNC plasma cutting machines and welding positioners. Based on their working method, they can be divided into backhoe buckets and front shovel buckets. Backhoes are suitable for excavating soil below the machine's stopping surface, while front shovels use a "forward and upward, forced cutting" action to excavate materials above the stopping surface. Depending on the operating environment, materials are divided into standard, reinforced, and mining types. Some models are made of high-strength steel plates to improve wear resistance. When an excavator bucket is damaged, a welding repair device is often needed to fix the bucket in place, and welding is performed using an external welding torch.

[0003] In the prior art, Chinese patent CN223382900U discloses a welding fixture for a loader bucket, including a welding table. Hydraulic grooves are provided on both the front and rear sides of the welding table. Hydraulic oil is disposed in the middle of the hydraulic grooves. A conveying pipe is fixedly connected to the left side of the welding table at the left end of the hydraulic grooves. A hydraulic pump is disposed at the left end of the conveying pipe, and the output end of the hydraulic pump is fixedly connected to the left end of the conveying pipe. An arc-shaped push rod is disposed on the left side of the hydraulic grooves, and the arc-shaped push rod passes through and is slidably connected to the middle of the welding table. A pad is fixedly connected to the top of the arc-shaped push rod, and a bucket is disposed on the top of the pad.

[0004] However, the bucket welding fixture provided in the above technical solution still has many shortcomings in actual use. For example, when welding the toothed plate of the excavator bucket, it is not possible to fix and splice multiple toothed plates. Multiple people are required to cooperate during welding, which makes welding and repairing the toothed plate of the excavator bucket more troublesome, resulting in poor practicality.
