  • Patent number: 5588642
    Abstract: A first threaded member (11) is supported by a housing (3) so as to be rotatable about its axis and to be unable to axially advance and retreat. While a second threaded member (22) is threadably engaged with the first threaded member (11) so as to be able to axially advance and retreat, the second threaded member (22) is supported by the housing (3) under the condition that its rotation about its axis is preventable. Under a clamping condition, the second threaded member (22) is strongly tightened by the first threaded member (11) which has been rotated by an impact wrench (16). Thereby, a metal mold (6) is fixedly pressed by a clamping member (5). When changing over from the clamping condition to an unclamping condition, large counterclockwise impacts are intermittently imposed to the first threaded member (11) by the wrench (16). Thereupon, the first threaded member (11) is rotated counterclockwise little by little by those impacts.

  • Patent number: 5324013
    Abstract: An improved clamp assembly includes a first clamp jaw having a plurality of incremental teeth on a lower surface which selectively mate with teeth on a clamp body. The teeth on the first clamp jaw end at one end at a tooth root and at the other end on an incline beyond and above the predetermined location of a tooth root. In this way, the first clamp jaw may be reversed to provide fine control over the incremental adjustable position of the first clamp jaw relative to the clamp body. In another feature of the present invention the other clamp jaw is a wedge-type clamp jaw having a threaded member with two enlarged portions received in a bore in the clamp jaw. The enlarged portions ensure that the threaded member is effective to move the wedge clamp jaw upwardly and downwardly relative to the clamp body. This is an improvement over prior art wedge-type clamp jaws which required complicated spring arrangements.

The spindle nut (7) is displaceably guided in a longitudinal recess (9) of the bed (1), is spring-loaded in the direction toward the fixed jaw (spring 18), and is provided with a cross pin (17). The cross pin (17) is adapted to be anchored in a series of downwardly open slots (20, 21, 22) rectangular in cross section. Upon tightening the previously released spindle (5), the pin (17) slides to the subsequent slot (21) and engages therein, whereupon the horizontal component of its obliquely upwardly direction movement pushes the movable jaw (3) forwards for clamping the workpiece (4).

  • Patent number: 4243213
    Abstract: The invention concerns an adjustable precision grinding and machinist vise which has a novel mechanism for precisely clamping metal pieces, tools, and other articles between a movable jaw and a stationary jaw. The vise is made such that it can be mounted on larger machines such as lathes, drills, milling machines, surface grinders and the like. The device employs a series of notches in the base as a guide means to stabilize clamping. A pin engages, at its lower end, a guide with opposite flanges which guide also has a central wedge with an arcuate load bearing surface. The pin extends through a rotatable clamp disposed within an angling shoulder on the movable jaw. The pin is disposed through the movable jaw and into a chamber in the base for engagement in the guide means to thereby insure precise positioning.
