Abstract
The housing of a grinding spindle unit is pivotably mounted by way of a pivot axle on the receiving part of a grinding machine, e.g., on a grinding headstock. The grinding spindle unit bears a grinding wheel which is driven in rotation. The actuation of an adjusting unit extends a pressure pin, which pivots the housing of the grinding spindle unit about the pivot axle and thus slants the grinding wheel. The pivot axle is in this case formed as a film hinge through a zone of targeted elastic material deformation. A tensile spring device brings about constant contact between the pressure pin and the receiving part.
Claims14
A grinding machine device with a grinding spindle unit, which has a motor-driven drive shaft mounted therein and a grinding wheel fastened to one end thereof, and with a pivotable mounting of the grinding spindle unit on a receiving part of the grinding machine, wherein, due to the pivotable mounting, different inclinations of the drive shaft with respect to a reference line are set, wherein
- a) the grinding spindle unit is connected via zones of selective elastic material deformation to the receiving part and is supported thereby;
- b) the zones of selective elastic material deformation are located in the first end region of the drive shaft facing toward the grinding wheel;
- c) an adjusting unit, which, upon activation, exerts an actuating force acting on the grinding spindle unit, which is directed transverse to the longitudinal axis of the drive shaft and of which the inclination is controlled via the zones of selected elastic material deformation, is located in the second end region of the drive shaft opposite the grinding wheel.
