The new Eagle Thread Verifier (ETV) automatically helps prevent improperly tapped parts from reaching final assembly, offering manufacturers a reliable method of eliminating expensive rework, and saving production time and cost.
Unlike conventional thread gauges, the patented ETV automatically identifies and alerts operators to the following conditions: Thread depth, size, location, squareness, untapped hole, or broken tap in hole, and incorrect pitch diameter. The ETV can stop the line or signal rejection of the unsuitable part. Corrections to the tapping process or tool replacement can be made immediately, eliminating further inaccurate production.
In operation, a commercial single or multi-spindle motor-driven test plug rotates within a tapped hole and monitors the torque. A visual torque monitor provides a real-time digital display of the torque reading. The ETV control compares the torque values to predetermined minimums and maximums, and indicates whether the holes tested are to depth, to the proper size, in the correct location and square to the part surface. Even at high production rates, the ETV reliably and consistently completes test cycles in seconds, adding no time to existing production cycles, and avoiding the errors of manual gauging and inspection.
The ETV can be mounted on a machine slide in a production system to probe and verify the proper thread at the point of machining or as an independently controlled stand-alone station, to check thread depth and size before shipment or assembly. In both cases, automatic multi-spindle motors can be arranged to check complete hole patterns simultaneously. A RS-232 port is available, for you to connect a monitor and a printer, to visually see the gauge results or a printed report to certify the inspection of the tapped holes. www.eaglethreadverifier.com
