Stud Bolt Detection Socket

This socket contains an internal plunger attached to an external collar. The collar is attached to the plunger by a roll pin. The roll pin passes thru the collar then thru a slot in the socket and then thru the plunger. The roll pin exits the plunger thru a slot on the opposite side of the socket and back into the collar.

The socket will be attached to a rundown spindle. When the spindle advances toward the stud bolt the plunger will contact the stud part of the fastener. As the spindle advances further the plunger will be pushed further up in the socket. This pushes the collar up also. When the collar is pushed back far enough it will activate a switch. The switch is tied to a Programmable Logic Controller. The Programmable Logic Controller then uses this information for accept/reject tracking.


By using this type of socket stud bolts or the lack of a stud can be detected and then tracked so that incorrect parts do not reach the end user.
