Description

Technical Field

[0001] The utility model relates to the technical field of excavator bucket production, in particular to a welding device for wear-resistant plates of excavator buckets. Background Technique

[0002] An excavator, also known as an excavation machine or a power shovel, is an earthmoving machine that uses a bucket to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them onto a stockpile. The materials excavated by the excavator are mainly soil, coal, sediment, as well as pre-loosened soil and rock. From the development of construction machinery in recent years, the development of excavators has been relatively rapid. Excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator are: operating weight (mass), engine power, and bucket capacity.

[0003] When welding an excavator bucket, a wear-resistant plate needs to be welded to the bucket. When the existing welding device welds the excavator bucket, it usually needs to use a lifting device to lift the bucket so that the area to be welded is presented in front of the operator. During welding, the bucket is not firmly fixed and is prone to shaking, which affects the welding quality. At the same time, there is a problem that the bucket slips and falls during lifting, which affects the personal safety of the operator. At the same time, the existing device is not convenient for fixing and welding buckets of different sizes, does not have wide adaptability, causes inconvenience to welders, and has poor practicability. Therefore, we propose a new welding device for wear-resistant plates of excavator buckets. Content of the Utility Model
