苏联工人采用了一种在鑽床上銑切螺釘槽的簡單夾具。使用这种夾具可以使銑切时间縮减到15秒鐘一个。 夾具的結構如图1。夾具体(可以利用廢旧的活塞来制造),用螺栓固定在机床台面上。被加工的螺釘可以利用手柄1夾紧在压板和底板中間的定位孔中。根据工件直径的不同,在压板和底板中間鑽 Soviet workers used a simple fixture that milled the screw slots on the drill press. With this fixture, the milling time can be reduced to 15 seconds. Fixture structure shown in Figure 1. Clamp body (which can be used to manufacture waste piston), bolted to the machine table. The screw to be machined can be clamped in the positioning hole in the middle of the pressure plate and the bottom plate by the handle 1. According to the different diameter of the workpiece, the middle of the platen and floor drilling
