Sensor device for geometrically testing parts
First Claim
Patent Images
1. A sensor device for geometric testing of parts, able to determine a position of a sensor body when the sensor body enters into contact with a part to be tested, the sensor device comprising:
- a case;
an engine;
a contact rod, motorised between an extended position and a retracted position relative to an inside of the case;
a microcontroller for controlling the movement of the rod;
a magnetic sensor, which cooperates with the contact rod to detect a position thereof; and
a counter-brace or restraining part, which forms a friction-contact counter-brace of the contact rod with a rotating axis of the engine, said a counter-brace or restraining part being fixed on said case.

Abstract
A feeler device for geometrically controlling parts, capable of determining the position of a feeler member when it comes into contact with a part to be controlled. The feeler device includes a motorized contact rod movable in translation inside a housing and a microcontroller for controlling the movement of the rod. The contact rod is driven in translation by friction with an element linked to the rotary shaft of a motor, and the contact rod cooperates with a magnetic sensor in order to detect the position of same.
