A method of assembling a gas sensor, assembly equipment of the gas sensor, ring instrumentation method of finches instrumentation member, and the cylindrical body of the ring instrumentation method

摘要

even if the sensor element is a warped, it provides a method and apparatus which can be assembled reliably gas sensors. In a state where the lower end portion inserted in the holding stage of the recessed portion of the sensor element, the upper end portion of the sensor element is a holding step, an upper holding state to the upper holding state in which the upper end to retain the sensor element along the vertical direction the finches a fitting step of fitting a through hole instrumentation members, the lower end of the upper holding state is switched to the lower retaining state of the sensor element holding along the vertical direction finches instrumentation member of predetermined and ring a switching step of reaching the instrumentation position, repeated for a plurality of finches instrumentation member, whereby after obtaining an intermediate assembly, and sandwiching the intermediate assembly from the side by the centering means, minimizing the outer diameter In did on oak, and mounted around the cylindrical body to the intermediate assembly.
