Pressure measuring apparatus for steel rail grinding head

Abstract

本发明提供了一种钢轨打磨头的压力测量装置。该装置主要包括:压力测头组件、2套转轴组和底座组件,压力测头组件的内轴座与转轴组的转轴实现轴孔连接。定轴板和调整轴套实现内轴座在转轴上的轴向定位。转轴组的转轴与底座组件的轴座实现轴孔连接。定轴板和角度调整盘实现轴座在转轴上的轴向定位。本发明实施例的装置有效地解决了钢轨打磨技术试验台的打磨头,在与竖直线成不同夹角情况下,其砂轮施加于钢轨轨头实际压力测量的需求,可以测取打磨头砂轮在不同夹角情况下施加于钢轨轨头的真实压力,该测量数值可为打磨头施加压力的控制、校正打磨压力,以及打磨工艺参数的确定,提供决策依据。
The invention provides a pressure measuring apparatus for a steel rail grinding head. The pressure measuring apparatus mainly comprises a pressure probe assembly, two rotating shaft sets and a pedestal assembly, wherein the inner axle seat of the pressure probe assembly and the rotating shafts of the rotating shaft sets realize shaft-hole connection. A shaft fixing plate and an adjusting spindle sleeve realize axial positioning of the rotating shaft on the inner axle seat, and the rotating shafts of the rotating shaft sets and the axle seat of the pedestal assembly realize shaft-hole connection. The shaft fixing plate and the adjusting spindle sleeve realize axial positioning of the rotating shaft on the axle seat. The pressure measuring apparatus effectively meets the actual requirement for measuring actual pressure applied on a steel rail head by a grinding wheel of a grinding head, when the grinding head on a steel rail grinding technology testing bench is at different included angles to a vertical line, and measures the actual pressure applied on the steel rail head by the grinding wheel of the grinding head under different included angles. The measured values provide decision making basis for controlling the pressure applied by the grinding head, correcting the pressure applied by the grinding head and determining the grinding process parameters.
