System and method for verifying screw threads

摘要

A thread gauge inspection apparatus includes a receiving member to hold a reference thread gauge and a motor to bi-directionally rotate the reference thread gauge. A counter counts a number of turns the reference thread gauge is rotated by the motor, and a torque monitoring device monitors the torque produced by the motor as the reference thread gauge is rotated. A controller, when the monitored torque exceeds a predetermined value, causes the motor to stop rotating the reference thread gauge and causes the counter to stop counting the number of turns the reference thread gauge is rotated. The controller compares the count produced by the counter with an inputted specific turn count and indicates the thread quality of threaded hole or a threaded stud passed inspection when the count produced by the counter is equal to the inputted specific turn count.

主权项

1. A thread gauge inspection system, comprising:
a reference thread gauge having unique identification; a thread gauge inspection apparatus having a receiving member to hold said reference thread gauge; and a control system in operative communication with said thread gauge inspection apparatus; said control system determining the status of the identified reference thread gauge, the status of the identified reference thread gauge being either approved for inspecting the thread quality of a machined thread or not approved for inspecting the thread quality of the machined thread; said control system communicating the determined status of the identified reference thread gauge to said thread gauge inspection apparatus.
