Abstract

1363163 Tool clamps KOMBINAT UMFORMTECHNIK ERFURT VEB 14 Feb 1972 6810/72 Heading B3H A tool clamp comprises a clamping pin 1 with an enlarged head 17 at one end and mounted on a hinge pin 6 at the other end which is pivotally mounted in a piston-rod head 5 connected to a double-acting hydraulic cylinder 3 by a pistonrod 4. The ends of the hinge pin 6 are wedge shaped transversely and are guided in slots in the legs of an inverted U-shaped frame 2. The cylinder 3 is integral with a pair of wedges 7 which act between the base of the frame 2 and a pair of supports 8 in which the piston-rod head 5 is rotatably mounted. In operation a tool plate 9 is clamped to a ram plate 10 by the pin 1 which is initially inclined, Fig. 2, and pivots about the hinge pin to the vertical position, Fig. 1, before being moved axially by the wedges 7. The tool plate 9 has a keyhole aperture, Fig. 4 (not shown), for the head 17. The pin 1 is screwed into the hinge pin 6 to allow for adjustment, Fig. 5 (not shown). Limit switches (11), (12), (13), Fig. 7 (not shown), are used to control the clamping pin position.
