Waviness measuring machine of inner sprial race for ball screw nut

摘要

grinding pattern measuring device for ball screw nut according to the present invention for measuring target ball screw nut supporting means for rotatably supporting , parallel bars provided parallel to the center for the rotation of the ball screw nut , the load is supported on the parallel bars , measuring means for measuring the inversely related inversely related between the helical groove of the ball nut and screw , the inversely related and display means for displaying the measured inversely related in the measuring means , in the longitudinal direction of the parallel bars inversely related and transfer means for transferring the measurement means , and the parallel bars in a direction parallel to the linear reciprocating motion , the spiral groove to be measured including 3D inversely related adjustment means for providing data for inversely related features a configured . ;
