Automated Go/No Go checking fixture

In this video you can see a simple example of automation of a checking fixture controlling characteristics of a part by Go/No Go gauges. This fixture is composed of a manual checking fixture to which we have added air cylinders whose air pressure is controlled by manometers, and a PLC that manages the controls sequence to detect potential errors.

This type of checking fixtures is perfect to carry out controls frequently because its cycle time is very short. The repeatability of this type of fixtures is very high as the cylinders pressure regulation is very sensitive, which make them stop at the slighest friction. Thanks to this solution, the process of detecting faulty parts is much more reliable than during a manual process, where the result may be more subjective depending on the pressure applied by the user on the Go/No Go controls.

A meter counting faulty parts enables to get a strict control as this meter can only be set to zero by a person having the unlock key for it.

Control systems like this one help making the adjusting of production means easier.
