The periphery of a selected crankpin is ground while the crankshaft rotates about an axis which is parallel to the axis of the crankpin. The decreasing diameter of the crankpin is monitored by one or more sensors which are connected with a detector serving to transmit signals to the controls of the grinding machine. Retention of the sensors in continuous contact with the circulating crankpin is ensured by an elongated guide which supports the sensors and the detector and is mounted on the piston rod of a cylinder. The latter is pivotable in a holder which is reciprocably or fixedly secured to the table or to the understructure of the frame of the grinding machine. A coil spring in the cylinder biases the piston and the piston rod in a direction to maintain the forward end of the guide in continuous contact with the periphery of the circulating crankpin.
Apparatus for monitoring the diameters of round objects, particularly of substantially cylindrical workpieces during their treatment in a machine tool such as a grinding machine, comprising supporting means defining a predetermined axis and arranged to mount objects in positions such that the axis of the object which is mounted in said supporting means is parallel to said predetermined axis and the object is free to circulate about the predetermined axis along a predetermined path;
