Description

Technical Field

[0001] The utility model relates to the field of material welding, in particular to a grinding machine limiting device which is convenient for grinding operations. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. A vertical grinder is one of the grinders. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing.

[0003] During the grinding operation, the existing grinder can only clamp the processed parts manually and cannot adjust the azimuth angle. When different end faces need to be processed, the workpiece needs to be removed and re-clamped. The re-clamping process greatly reduces the work efficiency and also brings great inconvenience to the staff. A solution is proposed below to solve the above problems. Utility Model Content
