Claims (1)

Application: in mechanical engineering for a clip of details at machining on milling machines. The vice contains a body 1, a fixed 2 and a movable 3 jaws, a lead screw 4. The mechanical hydraulic amplifier is fixed on the lead screw 4 at the handle 10. The piston 6 transfers the clamping force from the cylinder 5 to the moving jaw 3 via the rod 7. The plunger 8 is spring-loaded relative to the cylinder 5 by a spring 9, providing the return of the plunger 8 when unclamping the part. The hinge frame, consisting of the lever 14, the sleeve 15, the screw 16 and the lever 17, is used as a support for the movable jaw 3 through the lead screw 4. To transfer the movable jaw 3 to a different position, a bevel gear transmission 20 and a handle are used. The frame eliminates the bending moment in the body, allowing you to accurately base the clamped part. The vice for simplicity of the design significantly exceeds the known analogues, allows developing a large clamping force with a very high precision of the clamping part and is convenient in operation. 1 sec. and 4 h. n. f-ly, 3 ill.
