Steel rail fat edge grinding unit
The invention discloses a steel rail fat edge grinding unit which comprises a transverse moving mechanism, a grinding motor, a grinding unit frame, a deflection mechanism and adownward pressing mechanism, wherein an output shaft of the grinding motor is connected with the grinding wheel through a transmission mechanism, and the grinding wheel is switched between the working state of axial grinding and the working state of tangential grinding through the transmission mechanism; the grinding unit frame is used for installing the grinding motor and is movably connected to the transverse moving mechanism, and the transverse moving mechanism can drive the grinding motor to achieve transverse moving operation; the deflection mechanism is connected between the grinding unit frame and the grinding motor, and the deflection mechanism can drive the grinding motor to achieve deflection operation; and the downward pressing mechanism is connected between the deflection mechanism and the polishing motor, and the polishing motor can be driven by the downward pressing mechanism to achieve lifting and downward pressing operation. The technical problems that an existing grinding device is single in strategy, the grinding mode cannot be adjusted according to actual needs, and the requirements for large grinding amount, removal of plastic fat edges of the steel rail and satisfaction of the profile and the surface roughness of the ground steel rail with the requirements can not be met at the same time can be solved.
本发明公开了一种钢轨肥边打磨单元，包括：横移机构；打磨电机，其输出轴通过传动机构与打磨砂轮相连，通过传动机构实现打磨砂轮在轴向打磨与切向打磨之间工作状态的转换；用于安装打磨电机，并可活动地连接至横移机构的打磨单元架，通过横移机构能带动打磨电机实现横移操作；连接于打磨单元架与打磨电机之间的偏转机构，通过偏转机构能带打磨电机实现偏转操作；以及连接于偏转机构与打磨电机之间的下压机构，通过下压机构能带动打磨电机实现提升及下压操作。本发明能解决现有打磨装置策略单一，无法根据实际需求调整打磨方式，不能同时满足较大磨削量要求，去除钢轨塑性肥边，又能够保证打磨后钢轨廓形、表面粗糙度满足要求的技术问题。
