Document Type and Number:
Japanese Patent JP3341393
Kind Code:
B2
Abstract:
PURPOSE:To enable the weld strength of work to be surely measured with good reproducibility. CONSTITUTION:A weld-strength measuring apparatus 3 comprises a structural portion 5 and a control portion, and the structural portion 5 comprises a work holder 57 in which an explosion-proof valve device 17 is set, an outer cylinder 53, an inner cylinder 55, a probe holder 5505, and a work holder 59 to be electrically connected to the bottom surface 1713 or projecting portion 1719 of the explosion-proof valve 1701, with a pressure-oil passage communicating with the space portion 1723 of the explosion-proof valve device 17 and formed in the outer cylinder 53, the inner cylinder 55 and the probe holder 5505, and a disk 1703 welded to the projecting portion 1715 is electrically connected to the outer cylinder 53, and the hydraulic pressure of pressure oil is detected by a pressure sensor 7 and the electrical connection between the outer cylinder 53 and the work holder 59 is detected by a conduction sensor 8, and the control portion comprises a pressure-oil feeder unit for feeding and regulating the pressure oil to the passage, a pressure gauge for detecting and outputting the hydraulic pressure at the moment when the electrical connection between the projecting portion 171 5 and the disk 1703 is interrupted according to the detection results of the pressure sensor 7 and the conduction sensor 8, and a control unit.
