AUTOMATIC INSPECTION DEVICE FOR CONCENTRICITY OF STEPPED CYLINDRICAL BODY

摘要

PROBLEM TO BE SOLVED: To constitute an inspection device for concentricity of a stepped cylindrical body so that (a) the products are efficiently inspected as many as possible, (b) the inspection accuracy is sufficiently high, and (c) the mechanism is simple. ;SOLUTION: This automatic inspection device is constituted so that a rectilinear reference rail 11 of which the side is formed into a sufficiently smooth vertical face is arranged, two driven fixed pulleys 15, 16 are arrannged so as to keep a space nearly conformed to the neck part diameter of an object to be inspected against the reference rail 11, slide pulleys 17, 18 energized on the reference rail 11 side are arranged between the driven fixed pulleys 15, 16, a driving pulley 14 connected to a driving motor is arranged in rear of them, and an endless belt is laid between the respective pulleys so as to form a belt circulating passage. A contact plate interlocking with a micrometer is arranged under the reference rail 11, and a detecting part housing a detecting circuit electrically perceiving the object when the object is contacted with the contact plate, is formed.;COPYRIGHT: (C)1997,JPO
