1. Description
Three-jaw self-centering chucks are mostly used in metal machine tools. They can self-center to clamp or hold round, triangular or hexagonal and other shapes of outer or inner surface work-pieces for various machining and clamping. The tightening force is adjustable and the centering accuracy is high, which can meet the accuracy requirements of ordinary machine tools.
The three-jaw self-centering chuck standard is an important basis for product design, manufacturing, and acceptance, and it also provides a reference for the host computer.
Basic structure and working principle: The three-jaw self-centering chuck uses three screws to fasten the chuck to the flange of the machine tool through the screw holes on the end face of the disc body. Insert the wrench into any square hole of the gear. When the wrench is turned, the pinion gear drives the coil to rotate. The rotation of the thread on the end of the coil drives the three jaws to move forward or separate at the same time.
