Abstract
A turret tool rest ( ) includes a turret ( ) movably supported on a base ( ), on which desired tools can be mounted at predetermined indexable angled positions. A pair of coupling elements ( ), which can be engaged with each other, are arranged between the base ( ) and the turret ( ). The coupling elements ( ) are moved between an engaged position at which they are mutually engaged to fixedly hold the turret at respective indexed positions on the base, and a disengaged position at which they are mutually disengaged to permit the turret to be rotationally indexed. A spring-loaded plunger unit ( ) serves to prevent the turret ( ) from freely rotating on the base ( ),until the coupling elements ( ) are fully engaged with each other, during the moving operation of the coupling elements between the engaged and disengaged positions. The plunger unit ( ) includes a plunger ( ) retractably provided on the turret, a countersink ( ) fixedly provided on the base to be engaged with the plunger when the turret is located at the engaged position, and a coil spring ( ) or biasing the plunger to maintain the engagement between the plunger and the countersink.
