0976CA In the present invention, a toolholder assembly is provided with a mechanism for adjusting the angular orientation of the toolholder with respect to the longitudinal axis of the toolholder. A tool mounting sleeve adapted to receive and hold a standard toolholder is rotatably mounted to a tool block. A shaft extends from the rear of the sleeve and projects from the tool block. A pivot arm is fixedly secured at one end to the shaft and is pivotally secured at its other end to an adjustment block. The adjustment block moves linearly along an adjustment rod which is fixed to the tool block. Means are provided for securing the adjustment block at any position along the adjustment rod. The mounting sleeve, and thus the toolholder, can be rotated by repositioning the adjustment block along the adjustment rod. |
