Title:
DEFECT DETECTION METHOD AND DEVICE FOR INSULATOR CAP
Document Type and Number:
Japanese Patent JP3774122
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a defect detection method of an insulator cap part in which automation of detection is possible and precise inspection of the defect of the cap part can be done, and appropriate quality control can be performed.
SOLUTION: A jig fixture 5 is inserted from multiple directions between the cap part 2-1 and the cap part 2-2 of the insulator 2 and, by applying stress on the cap part, the defect of the cap part is detected. The device for implementing the defect detection method of the insulator cap part is constructed of a base table 4 for setting the insulator to be inspected, a plurality of jig fixtures 5 that are provided on the base table and constructed to be capable of inserting in and separating from between the cap part and cap part of the insulator set on it, a stress detection means 7 that is provided on the insulator set, and calculates the stress applied on between the cap part and cap part, and a control means 8 that controls the movement of the fixtures and detects the defect of insulator cap part based on the stress applied on between the cap part and cap part, that is calculated by the stress detecting means.
