Technical Field
[0001] The present application relates to the technical field of rail processing, and in particular to a grinding device for grinding rail welds. Background Art
[0002] When rails are welded at the rail base, a weld is formed at the welding point between every two rails. Usually, the thickness of the weld is higher than the surface of the rail to form a weld nodule protruding from the surface of the rail. The weld nodule must be polished off. In the prior art, a manipulator polishing device is provided to improve the polishing effect of the weld through the rotatable range of the manipulator itself.
[0003] Since rails have different shapes, existing rails usually include a rail head, a rail waist and a rail foot, wherein the arc angle between the rail head and the rail waist is different from the arc angle between the rail waist and the rail foot. Therefore, when grinding the weld nodules at the welds, different grinding heads are required to grind them. As a result, when processing the outer surface of the mold frame in batches, the staff always need to frequently replace the grinding heads, which is quite inconvenient, and therefore needs further improvement. Utility Model Content
