Name:Thread Verification Unit -- TVU
Specifications:TVU
Usage:Thread Verification Unit TVU
Thread verification.
Together with a separate linear actuator, quickly and automatically checks threaded holes (or external threads) by powering a probe (or ring gage) into and out of the part. GO gaging, NO GO gaging, and combination gaging are all possible.
Sensitive high speed drive allows the probe to stop in case of missing or improperly formed threads. This registers a fault, creating a "reject" signal.
Will check blind holes accurately for thread depth.
Will not jam or stick in undersize (reject) threads. In automated applications, rejects can be separated out without stopping the process.
Does not subject the part (or the Spindle) to high force or torque levels.even with a reject.
Three basic models fit most applications.
Quick to set up and use. Will mount in any orientation.
Inspects a wide range of threads, with probe replacement the only changeover. The tool-free probe holder allows for quick change-out of probes.
