立柱式钻模在苏联已广泛采用,我国近几年来也朝这个方向发展。它的种类很多,视其夹紧装置的机构不同,大致有五、六种,其中最常见的一种是锥体锁紧,而在苏联工厂中则多用螺纹来锁紧,它的特点是制造方便、夹紧力大、方法较新型,实践证明也的确如此。现在我把它的构造叙述于下:如图所示,系利用活柱钻模加工连杆小头孔的一个实例。工件外表面是毛坯的,靠到二个可以调节的偏心螺钉9上,先初步确定其位置。精确的定位则依靠钻模板1下降,用锥形套筒7来对准工件的中心。_从图上结构来看:1为钻模板,由螺帽2固定在活柱5上。活柱滑配在夹具体3的导孔内。操纵手柄8可以上
Column drilling has been widely adopted in the Soviet Union, our country also in recent years in this direction. It is a wide variety, depending on the mechanism of its clamping device, roughly five or six, the most common of which is the cone lock, while the Soviet Union is the use of more threads to lock, which is characterized by manufacturing Convenient, clamping force, the method is more new, the practice proved so. Now I will describe its structure in the next: As shown in the Department of the use of live-column drilling rod connecting rod an example of a small hole. The outer surface of the workpiece is rough, by two adjustable eccentric screw 9, the initial determination of its position. Precise positioning depends on the drill template 1 down, with a tapered sleeve 7 to align the center of the workpiece. _ From the diagram on the structure: 1 for the drilling template, the nut 2 is fixed to the column 5. The movable column slides in the guide hole of the clamp body 3. Joystick 8 can be up
