FLANGE-FASTENING SKILL DETERMINATION DEVICE AND FLANGE-FASTENING SKILL DETERMINATION COMPUTER PROGRAM STORED ON MEDIA

摘要

The flange fastening skill determination device includes a receiving unit that receives an output signal output from each of the tightening force detectors formed correspondingly to a plurality of bolts tightened to connect the flanges, A measuring section which obtains a plurality of measurement results indicating a transition of each output signal from the time when the tightening operation of each of the plurality of bolts is received to the completion of the tightening operation received by the receiving section; A first calculation result indicating a deviation of an output signal value of each of the tightening force detectors during a bolt tightening operation and a second calculation result indicating a deviation of an output signal value of each of the tightening force detectors at the time of tightening a plurality of bolts And a third calculation result indicating the degree of tightening force at the completion of tightening work of the plurality of bolts And a judging section for judging the function of the subject related to the tightening work of each bolt as one of three or more functional levels based on the results of collating the respective functional judgment items with the judgment criteria And an output unit for outputting a determination result by the determination unit.
