CALIBRATION DEVICE AND CALIBRATION METHOD FOR MEASUREMENT INSTRUMENT

摘要

It is a calibration device for a measurement instrument for measuring a compressive force or a tensile force in a longitudinal direction exerted to a linear body from a predetermined correlation. A stopper part for fixing the linear body is fixed at a one end side entrance and a push/pull movable part for enabling the linear body to be pushed and pulled in an insertion/withdrawal direction at an other end entrance is fixed, so that the relative positions of the stopper part and the push/pull movable part with respect to a sensor main body cannot be changed. A force detector measures the force in the insertion/withdrawal direction exerted from the push/pull movable part to the linear body. The force detector is interposed between the push/pull movable part and the linear body.

1. A calibration device for a measurement instrument, said measurement instrument including:
a sensor main body provided with a one end side entrance and an other end side entrance which a linear body having a flexibility is inserted to and withdraw form; a detection part allowing a displacement of said linear body which is in communication with said sensor main body; and a position sensor detachably provided in said detection part and configured to detect a position of said linear body, said measurement device measuring a compressive force or a tensile force exerted in a longitudinal axis direction of said linear body using a predetermined correlation based on a position of a linear body detected by said position sensor, said calibration device comprising: a stopper part for fixing one end side of said linear body at said one end side entrance; a push/pull movable part configured to locate a front side on a side opposite to said one end side and to be pushed and pulled in an insertion/withdrawal direction at said other end side entrance; fixing means which fixes said stopper part and said push/pull movable part so that relative positions thereof with respect to said sensor main body cannot be changed; and a force detector interposed between said push/pull movable part and said linear body and configured to measure a force in an insertion/withdrawal direction exerted from said push/pull movable part to said linear body.
