Description

Technical Field

[0001] The utility model belongs to the technical field of deburring equipment, in particular to a workpiece deburring device for a manipulator. Background Art

[0002] When machining mechanical workpieces, it is often necessary to cut and forge metal plates. Sharp edge burrs are easily generated on the edges of the plates after cutting, which affects the assembly between structures and is unsafe.

[0003] The existing burr removal device does not have a protective device specifically for protecting the motor. The motor is easily damaged once it encounters rain. In addition, the grinding mechanism fixedly connected to one end of the motor shaft is easily worn and loosened after long-term use. At this time, the staff needs to replace it in time. The installation and disassembly of the grinding mechanism during replacement is relatively cumbersome. Once the grinding mechanism is not properly fixed to the motor shaft, it is easy to affect the progress of removing burrs from the workpiece. At the same time, after the grinding part is damaged, the staff needs to replace the connecting part connected to the motor shaft and the grinding part together, which causes a waste of resources.
