Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts processing, in particular to a mechanical parts burr removal machine. Background Art

[0002] Some burrs on mechanical parts are caused by plastic deformation during cutting, some are flashes from casting, die forging, and other processes, and some are residual materials from welding extrusion. The existence of burrs will have adverse effects on many aspects of parts processing accuracy, assembly accuracy, reprocessing positioning, and appearance quality. When removing burrs, a special mechanical parts burr removal machine is needed to assist;

[0003] Traditional deburring machines for some mechanical parts use grinding motors to remove burrs from mechanical parts through grinding wheels. The positions of the grinding motors and grinding wheels are fixed, and personnel are required to constantly change the grinding surface of the mechanical parts to cope with it;

When removing burrs, due to the fixed position of the grinding motor and the grinding wheel or the limited adjustment range, it is easy to be time-consuming and laborious or the grinding is not in place. The adaptability to the processing of mechanical parts of different sizes is poor. For this reason, we propose a mechanical parts burr removal machine. Utility Model Content
