Downward pressing control method for polishing unit
The invention discloses a grinding unit downward pressing control method which comprises the following steps: S11) setting a downward pressing execution mechanism to be in a locking state, and ensuring that the length of the downward pressing execution mechanism is locked at a fixed value; (S12) when a grinding head of the grinding executing mechanism runs to the wave trough position of the top face of the steel rail, the buffer element is subjected to additional downward tensile deformation, and upward additional tensile force is generated, so that the extrusion contact force between the grinding head and the top face of the steel rail is reduced, and the grinding cutting amount of the wave trough position is reduced; and S13) when the polishing head runs to the wave crest position of the top surface of the steel rail, the buffer element is subjected to additional upward thrust and generates downward additional downward pressure, so that the extrusion contact force between the polishing head and the top surface of the steel rail is increased, and the polishing cutting amount of the wave crest position is increased. The technical problems that according to an existing method, constant-power or constant-pressure grinding is adopted, the grinding force of wave crest and wave trough positions is basically the same, and the steel rail corrugation eliminating capacity is poor can be solved.
本申请公开了一种打磨单元下压控制方法，包括以下步骤：S11)将下压执行机构设置为锁定状态，保证下压执行机构的长度锁定在固定值；S12)当打磨执行机构的打磨头运行至钢轨顶面的波谷位置时，缓冲元件受到额外向下的拉伸变形，并产生向上的附加拉伸力，从而减小打磨头与钢轨顶面之间的挤压接触力，波谷位置的打磨切削量减小；S13)当打磨头运行至钢轨顶面的波峰位置时，缓冲元件受到额外向上的推力，并产生向下的附加下压力，从而增加打磨头与钢轨顶面之间的挤压接触力，波峰位置的打磨切削量增加。本申请能解决现有方法采用恒功率或恒压力打磨，波峰波谷位置打磨力基本相同，钢轨波磨病害消除能力差的技术问题。
