Measuring head for measuring equipment, multi-coordinate measuring instruments, and machine tools

摘要

A measuring head for measuring article contour positions comprises a casing with a feeler pin mounted in the casing for pivotal movement in three-dimensional directions. A separate spring biases the feeler element in a neutral position in each of the three dimensional movement directions and the feeler pin is movable against the bias in all directions in a measuring movement. The measuring head is provided for measuring equipment for multi-coordinate measuring instruments and machine tools and is provided with connections for a digital or an analog evaluation of the measured value. Preferably a plurality or rope elements are connected to the feeler pin to hold it in its coordinate zero position within the casing and to extend in the respective X, Y and Z directions and are in equilibrium with each other in their state of rest. The biasing means in the form of springs are arranged in parallel to each of the rope elements an exert a force in the direction of a coordinate zero position acting opposite to the measuring motions of the feeler pin.
