摘　　要： 为提高地下钻进机器人钻头的钻进效率,针对挤扩钻头的不同部位进行了力学分析,建立了钻头所需扭矩与钻进压力的数学模型;基于柱孔扩张理论,确定了钻头上各处挤扩应力的分布情况,得出了扭矩和钻进压力的计算表达式,通过对比实验数据,验证了计算方法的正确性。在此基础上,分析了螺旋角和螺纹宽度对钻头所需扭矩的影响,优化了挤扩钻头的结构参数。 In order to improve the drilling efficiency of the squeezed drill of the underground drilling robot, the force on different parts of the drill was analyzed and the mathematical model of the required torque and pressure were established. The distribution of with cylindrical cavity expansion theory and the formulas By comparing the experimental data, the correctness of impact of the helix angle and thread width on drilling structural parameters of the squeezed drill were optimized. squeezing stress on the drill was determined of torque and drilling pressure was obtained. the method was verified. On this basis, the torque and pressure was discussed, and the
