Description

Technical Field

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

[0002] Burrs may be generated on the turbine shaft during the processing process, and these burrs will affect the quality and performance of the turbine shaft. The deburring device can effectively remove the burrs on the surface of the turbine shaft, making its surface smoother and more uniform. Among them, the grinding wheel deburring machine is a common manual deburring device. The burrs on the surface of the turbine shaft are removed by grinding with a grinding wheel. In the process of manual grinding of burrs, the turbine shaft needs to be moved laterally so that the surface of the turbine shaft can be laterally ground and deburred. However, during the grinding process, the grinding wheel generates a feed force perpendicular to the tangential direction on the turbine shaft, which makes the turbine shaft move away from the grinding wheel. This may easily cause the grinding position to shift when the turbine shaft approaches the grinding wheel again, affecting the operator's grinding of the turbine shaft. In order to solve this problem, a new type of turbine shaft deburring device is needed. Utility Model Content
