Abstract

A fixturing device for holding a workpiece for processing by an induction hardening machine includes a first subassembly constructed and arranged to be attached to an induction coil subassembly which is movable into and out of position around the workpiece. A second subassembly, virtually identical in construction to the first subassembly, is attached to the induction coil assembly and the two subassemblies are spaced apart so as to face one another and so as to define therebetween a workpiece-receiving region. Each subassembly includes an L-shaped bracket with one leg configured for attachment to the induction coil assembly and the other leg configured with connecting rods for attachment to a holding block. There are three connecting rods, two in the form of cylindrical pins, and one, the center connecting rod, being externally threaded for connecting a holding block to the L-shaped bracket. The two cylindrical pins receive coil springs so as to spring bias the holding block. The threaded connecting rod receives a hex nut for setting the initial spring tension of the holding block relative to its movement toward the L-shaped bracket. The workpiece to be processed by the induction hardening machine is to be positioned between upper and lower centers. The procedure for utilization of the fixturing device is to place the workpiece on the lower center and then push the upper portion of the workpiece in between the two holding blocks, allowing these blocks to separate for added clearance by compressing the coil springs in each subassembly until the workpiece is properly aligned, at which point the upper center is lowered into position.
