Assembly Innovations: Ultrasonic Sensing System Ensures Correct Fastening Sequence
Whenever an operator must install several fasteners in a part at an assembly station, the issue arises: How do you ensure that the fasteners are tightened in the correct sequence?
In some cases, the installation sequence doesn't matter. The fasteners can be run down in any order. In other cases, such as joints that include a compressible gasket, the sequence is critical. Installing the fasteners in the wrong sequence could deform the gasket and create a leaky joint.
