초록 ▼

An improved clamp is disclosed in which a carrier plate is mounted slidably within a housing and is moved in one embodiment in a linear direction by means of an actuator. First and second arms are mounted in the housing and in angularly oriented guide slots within the carrier plate whereby, when the actuator moves the carrier plate, the arms move so that jaws at the ends of the arms converge at a clamping position. A pin in each arm is engaged in its own slot in the housing to insure that the jaws move along a predetermined path. In one embodiment of the invention only one of the arms is movable and the other arm is fixed. In a second, self-centering embodiment of the invention both arms move towards each other and equal and opposite bending stresses are induced in the arms which bend the arms within the elastic limit of the metal. The aforementioned Abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.

대표청구항 ▼

A clamp for holDing a workpiece, said clamp comprising: a. a housing; b. a linearly movable carrier slidably mounted in said housing; c. actuator means for causing relative movement between said housing and said carrier; d. first and second arms including, respectively integral first and second jaw means having gripping surfaces in opposition to each other for holding the workpiece therebetween, said arms being capable of being stressed under strain to bend them into an arcuate shape while holding the workpiece; and e. means for drivingly coupling at least one of said arms and the jaw means integral therewith to said carrier for displacement thereby and to said housing for limiting said coupled jaw means to linear movement in a direction perpendicular to the direction of movement of said carrier whereby the plane of said coupled jaw means is always parallel to the plane of the workpiece, said linear movement of said coupled jaw means being towards a clamping position adjacent said other jaw means and away therefrom when there is relative displacement between said housing and said carrier, and wherein said means for coupling said arm to said carrier and to said housing comprises an elongated slot in said housing and a pin integral with said arm and in engagement with said slot, the axes of said slot being substantially perpendicular to the direction of movement of said carrier, said coupling means further including guide means for displacing said one arm along a path at an acute angle to the direction of movement of said carrier comprising an elongated recess in said carrier, the recess in said carrier having generally opposed side walls, at least a portion of which bear against a portion of said arms.
