利用车床尾座顶置控杆健孔，具有同轴度高，成本低等一系列优点，但对于工程作业类专用车的取力箱、分动器等多孔箱体镗孔难找准孔位之间的距离，且操作难度大。对此，本文现介绍一种车床镗孔夹具，供广大工艺工作者参考。1车床模孔夹具结构该镗孔夹具较为简单（见图1），由转? The use of lathe tailstock top control rod hole, with high coaxiality, low cost and a series of advantages, but for engineering work special power take-off boxes, transfer boxes and other porous box boring difficult to find holes The distance between, and the operation is difficult. In this regard, this article describes a lathe boring fixture for the majority of workers reference. A lathe die hole fixture structure The boring fixture is relatively simple (see Figure 1)
