Longitudinal multipass profile knurling machine - has slides for crossbar of knurling head having radial slots knurled sliders movable by pairs of wedges

摘要

The machine comprises parallel stationary crossbars rigidly interconnected by slides and carrying centres for positioning a workpiece. Mounted on the slides, between the stationary crossbats, and adapted for reciprocating motion along the centres axis is a movable crossbar with a knurling head in whose housing there are radial slots. Sliders with knurls are movable in the slots by a device comprising self-braking wedges installed in pairs in each radial slot and stops interacting with the wedges, the stops being mounted on the stationary crossbars and being adapted for reciprocating motion.
