ABSTRACT:
An apparatus (10) for checking the diameter of an eccentric pin (8′) of a small-size shaft (8), for example a shaft for compressors, includes a support (16), a first arm (19) rotating with respect to the support (16), a second arm (22) rotating with respect to the first, a Vee-shaped reference device (28) carried by the second arm, a measuring device (25,26,24,37,38) associated with the reference device, limiting devices (29,29′,30,30′) for limiting the rotations of the arms and thrust means (33) for keeping the reference device in contact with the pin in the course of the checking. A hydraulic actuator (13) displaces the apparatus (10) from a rest condition to a checking condition, in which the reference device (28) is in contact with the pin (8′) to be checked, and vice versa.
