ABSTRACT:
A locking mechanism for the contouring head assembly of a belt grinding machine that employs multiple, parallel, abrasive grinding belts, and back-up shoes for pressing the belts against the surfaces on a workpiece to be ground. The locking mechanism secures the contouring head assembly to the bed of the grinding machine. The locking mechanism includes a protrusion, such as a ball, that is carried by the contouring head assembly and a pivotable arm with a socket defined near its free end. The pivotable arm is secured to a shaft that is driven by a rotary actuator, that is powered by a hydraulic motor. The socket engages the protrusion to securely support one side of the contouring feed assembly. A hydraulic cylinder forces a tapered plunger against the pivotable arm to enhance the locking action.
