苏联某工厂在加工青铜轴承的螺旋线油槽时,采用了一种高效率的靠模夹具,这种夹具既能夹紧工件,带动工件旋转,又能带动工件自动进退,所以能很快地车出油槽来。夹具安装在车床主轴上。夹具的结构并不复杂,如附图所示,一共只有九个零件。图中1是锥形套筒,直径大小和锥度,可以根据车床主轴来决定。套筒后端有螺纹,可以用长螺杆旋紧,长螺杆的另一端通过主轴孔,而 A factory in the Soviet Union in the processing of bronze bearings spiral groove, the use of a high efficiency by the fixture, this fixture can not only clamp the workpiece, the workpiece rotation, but also bring the workpiece automatically move forward and backward, so the car can be very fast Out of the tank. Fixture installed in the lathe spindle. Fixture structure is not complicated, as shown in the figure, a total of only nine parts. Figure 1 is a tapered sleeve, diameter and taper, according to the lathe spindle to decide. The rear end of the sleeve is threaded, which can be tightened with a long screw, the other end of the long screw through the spindle hole, and
