Hi,

Does anyone know of a sensor or system that can verify if a hole is threaded? This is for poke-yoke purposes and the system or sensor needs to be adjustable or programmable for different parts/configurations if possible.

Thanks,
Kevin

 

Cameras do this really well and inexpensively. At least mine do. I don't know about shrinkwrap solutions.

I have developed a system that is capable of detecting thread presence within a certain location inside a tapped hole. The basis of this system is reflected light. The system is not costly to set-up and is fully and easily adjustable to inspect a broad range of threads and nut configurations. If you have further interest please contact me via email

Eddy current thread testing is used a lot for thread detection. The low cost systems aren't good for much more than detection of the absence or presence of threads. However, a better instrument will provide much more capability and can be used to measure the quality of the threaded hole and can be used reliably to indicate shallow threads, deep threads, double tapped threads, etc. Here is a link to Zetec Incorporated and our "Thread Testing" application brochure.

The best company that we have found for thread inspection is the inductive and capacitive sensors from Automation Innovation, Inc. The capacitive sensors have standard resolutions from 0.0001 inches to 1 micro-inch. The base units inspect presence/absence, length/number of threads, minor diameter, thread pitch, etc. You can get it to gauge the thread - only aerospace needs that.

I've tried to reach tyhem but the web access seems not working, any idea how to reach them by phone or fax?

Found this url: http://automotiveoem.com/Automation-Innovation-Inc_4274.

The page lists a phone and a fax number in North Carolina USA.
