ABSTRACT:
A fast change set-up device for work on work supports wherein work blanks can be mounted to a number of work supports prior to machining and the upper work support can be quickly attached to a lower work support and locked thereto by rotating a handle so that the next piece can be machined. The shaft carries four cams for driving spring biased bolts which engage in grooves formed in locking pins and the cams have an indentation for locking the bolts in the grooves to hold the upper and lower work supports together so that machining can occur. After machining the upper work support can be removed from the lower work support and a second upper work support can be mounted to machine another workpiece.
