针对目前加工滚珠丝杠螺母时,回珠器孔与螺旋槽的相对位置无法现场检测的问题,提出了将直接测量转变为间接测量地方法,设计了一种新型的滚珠丝杠螺母内滚道位置度测量方法,构建了一套滚珠丝杠螺母内滚道位置度测量系统。利用该方法对滚珠丝杠螺母内滚道进行了位置度测量,并与理论值进行了比较。结果表明,该方法具有较高的测量精度及可靠性。研究结果可为回珠器与螺母内滚道的加工位置精度的测量奠定基础。 Aiming at the problem that the relative position of the bead return hole and the spiral groove can not be detected on the spot when the ball screw nut is processed currently, a method of converting the direct measurement into the indirect measurement is proposed and a new type of ball screw nut inner raceway is designed Position measurement method, a set of ball screw nut inner raceway position measurement system. The method was used to measure the position of the inner raceway of the ball screw nut and compared with the theoretical value. The results show that this method has high accuracy and reliability. The results of the research can lay the foundation for the measurement of the processing position accuracy of the ball return and the nut inner raceway.
