Description

Technical Field

[0001] The utility model relates to the technical field of bucket processing, in particular to a bucket grinding processing device. Background Art

[0002] Bucket refers to the bucket installed on the excavator, also called digging bucket. It is divided into backhoe bucket and front shovel bucket according to the working mode. The backhoe bucket is commonly used. When processing the bucket, the bucket body is generally bent and formed first, and then the side plate is welded and fixed by welding. After completion, the reinforcing ribs and structural parts for connection are welded to the outer wall of the body. In order to ensure that the bucket can use the bucket teeth to perform good shoveling work on the working ground during work, the bucket teeth and other parts of the bucket will be ground. Conventional grinding tools are generally grinding wheels, but the grinding surface of the bucket teeth needs to be set along the length direction of the bucket teeth, so the grinding of the grinding wheel depends heavily on the adjustment and control of the workers. Therefore, the existing technology mostly uses grinding belts for grinding, but the tightness of the grinding belts often relaxes during grinding, which will affect the efficiency of subsequent grinding. And because the grinding belt is generally installed at a fixed angle as a whole, it is still necessary to adjust the bucket teeth and other parts at different angles during the actual grinding process to ensure the efficiency of grinding.
