US 5,174,004 A · Radiator clamping jig

Abstract

A clamping jig releasably holds a workpiece of elongate cross section such as a radiator core. The jig includes an upright frame and a parallelogram-shaped horizontal articulated linkage having a pair of parallel side rails and a pair of end members pivotally connected to the ends of the side rails for movement about vertical axes. The side rails are spaced apart a distance greater than the width of a radiator core, and are moved by a pneumatic cylinder or other actuator so that the links pivot about their axes, and the side rails move closer together to clamp the radiator core between them. The clamping mechanism is operated by a foot pedal, for hands free operation. The vertical height of the parallelogram linkage may be readily adjusted, and hold-down elements are provided to exert a downward pressure on the radiator when it is held clamped between the side rails.

Dependent claims

A clamping jig suitable for holding a radiator core, said jig comprising:

an upright frame;
clamping means mounted on said frame, said clamping means including a parallelogram-shaped horizontal articulated linkage having a pair of parallel side rails, and a pair of end members each pivotally connected to a respective end of both side rails for movement about parallel vertical axes;
said side rails having a first position in which they are parallel to each other and spaced apart a distance greater than the width of a radiator core, and a second position in which they are spaced apart a distance equal to the width of a radiator core;
and
means for pivoting at least one said end member relative to said side rails to vary the spacing between said side rails, to move them between said first position and said second position so that a radiator core is releasably clamped between the side rails in the second position.
