(57) Abstract Objective ribe which can prevent the formation malfunction of the rivetThe tsuteingu device is offered. Constitution In upper part of XY table 1 '' in column 2 tsuThe te in the cylinder 4 of ribetsuteingumashin 3 which is supported the spurTo install separation sensor 31, with that distance sensor 31It extends from the work 11 which in XY table 1 '' is mountedDistance between distance sensor 31 is measured from the ru rivet end faceru. And, the measurable quantity with relative means 50 ribetsuComparing to 9 with the default value when it is set to correct jig 10When comparison it does, both agree, in ribetsuteingumashin 3 the tsute caulking formation is done. In addition, when both do not agree, thatReporting effect, it caulks and does not form.
