莫斯科铣床工厂制造了一个确保工件在两个相互垂直平面内定位和夹紧的夹具。该夹具安装在一台组合机床的工作台上。 在夹具体上紧固着支架7,这个支架是工件的定位、导向和支承基面。工作时在浮动油缸13有活塞杆的一端通入压力油。这时,活塞向右移动。摆杆3通过拉杆11和活塞杆12相连,它绕着转轴回转,并移动压板2,从而把工件推靠支架的支承面。浮动油缸向左移功,并转动摆杆9。与其相连的压板10将工件推靠支架
Mills Mills manufactures a clamp that secures and positions the workpiece in two mutually perpendicular planes. The fixture is mounted on a combined machine table. The clamp 7 is fastened to the clamp body, which is the positioning, guiding and supporting base of the workpiece. Work in the floating cylinder 13 has a piston rod into the end of the pressure oil. At this moment, the piston moves to the right. The pendulum rod 3 is connected to the piston rod 12 via a tie rod 11, which revolves about the axis of rotation and displaces the pressure plate 2 so as to push the work piece against the bearing surface of the cradle. Move the floating cylinder to the left and turn the pendulum 9. The pressure plate 10 attached to it pushes the work piece against the bracket
