<p>A pneumatic vice for automatic metalworking without hydraulic force amplifier comprising; a body box (1) where two screw spindles (17, 18a) are parallel mounted by bearings, a clamping lever (30a) mounted on the screw spindles by two nut (29, 32) with bearing journal, a drive motor (13) and two timing pulleys (65, 70) to move clamping lever (30a) which main fork-end with an swivel able upright (36, 37, 38) carry the movable jaw (15), a pneumatic cylinder (14) with two-part piston (78) mounted by a rotary push flange (79) on the end of screw spindle (18), four support roller (60) against the fastening plane (3) to resist bending moment from clamping force, two horizontal joint screws (42) which correct position of gripping list (44) and a fixed jaw (16). The drive motor move work piece against the fixed jaw and the pneumatic cylinder make the clamping force by moving the screw spindle (18a). An external pneumatic clamp move the work piece in Y-direction against studs (4 or 5) which have 35 alternatives places on the body deck (2).</p> |
