Claims
- 1. A device for measuring the dimensions of workpieces having a continuous or discontinuous surface during the course of machining, comprising a measurement sensor movable in one direction and in the opposite direction,
- a. a motor means for the motorized drive of said measurement sensor in one direction and in the opposite direction;
- b. a transducer whose movable element is rigidly connected with said measurement sensor,
- c. a recording means connected to said transducer for recording the signals emitted by said transducer;
- d. a pulse-detector means connected between said transducer and said recording means for controlling the running of said motor means; and
- e. a control means on which acts said pulse-detector means, said control means controlling said motor means, whereby said measurement sensor may gradually approach the surface to be measured and enter into contact with it and the dimension measured at the time of contact recorded, and the measurement sensor maintained at the dimension measured and recorded at said time of contact or displaced in the opposite direction for a period of time.
- 2. A device according to claim 1, wherein said motor means is a motor whose direction of operation is reversible.
- 3. A device according to claim 1, wherein said control means controlling said motor means is adjustable in time.
- 4. A device according to claim 3, wherein said control means is a mono-stable flip-flop adjustable in time.
