Title:
研削位置においてクランク軸のクランクピン直径を測定する装置並びに方法
Document Type and Number:
Japanese Patent JP4860083
Kind Code:
B2
Abstract:
An apparatus for checking diametral dimensions of crankpins and main journals in the course of grinding is provided. The apparatus includes a head with a Vee-shaped reference device and an axially movable feeler that contacts the surface of the pin to be checked, and an articulated support device, coupled to the grinding wheel slide that carries the head and enables it to keep contact with the surface of the pin during possible orbital rotations. A transducer in the head cooperates with the feeler for detecting its displacements and transmits signals to a processing and display device in turn connected with the computer numerical control of the grinding machine. The processing and display device processes the transducer signals with compensation values or coefficients stored in a memory unit for obtaining measuring signals output by the head that vary in a linear way in a wide range and for compensating errors due to temperature variations.
