DO NUT PERCEPTION DEVICE IN NUT EXISTENCE AND NONEXISTENCE AUTOMATIC SEARCH MACHINE

摘要

the invention or without automatic nut nut's browser to a sensing device for such, and more particularly, various types of is a nut sensing device to check whether or missing nut that is welded properly at each position in the process of production of spare parts for the automotive parts cylinder and sensing port configured using air pressure. ; The in the nut of the invention whether or not the browser automatically install the sense region (2) and the air outlet hole (4) having an air cylinder (1) is formed in each position the bed section 20 of the nut on the sensing device includes a frame (3), and , ; install the air cylinder (1) and the air supply pipe air pressure switch 7 and the connection here (6) able to receive an air pressure signal, and further Solid solenoid valve (5) as configured by installing the air can be supplied to the air cylinder, such as the present invention because the sense of the accuracy of the earth consisting of the presence or absence detection apparatus nut nut can check by touching the nut directly by the air pressure increases, the effect of the presence or absence of the nut to increase the confidence in the detected part for automobile, and the good feeling of the earth as structural durability to be used a long time, and it is possible to improve the confidence of the presence detection of a nut.
