在批量车削较长工件时,可使用该定位心轴。定位心轴用胀紧的方法被固定在车床主轴孔内,使用时辅以限位挡块来限制车床大拖板位置。这样对车削固定长度工件可节省对刀、测量时间,提高工效35％,并且保证了加工质量。定位心轴总成安装前,先旋转联接螺套7、挡杆9,将定位心轴调整到需要的长度,并拧紧锁母6和锁母8。再将定位心轴从车床左端送入车床主
This spindle can be used when turning large workpieces in batch. Positioning mandrel with a tightening method is fixed in the lathe spindle hole, when used in conjunction with the limit stop to limit the lathe position of a large carriage. This fixed-length turning the workpiece can save on the knife, measuring time, improve work efficiency 35%, and to ensure the processing quality. Before positioning the mandrel assembly, rotate the coupling nut 7 and the stopper rod 9 to adjust the positioning mandrel to the required length and tighten the lock nut 6 and the lock nut 8. Then locate the mandrel from the lathe left into the main lathe
