Abstract

The invention specifically discloses a multi-component-force sensor calibrating machine, which comprises an upper substrate and a lower substrate. The multi-component-force sensor calibrating machineis characterized in that the upper substrate is provided with a longitudinal testing mechanism; a fixing block for placing a pressurizing tool is arranged in the middle of the lower substrate; two sets of mutually perpendicular horizontal testing mechanisms are arranged between the upper substrate and the lower substrate; and each set of horizontal test mechanisms are arranged symmetrically on thetwo sides of the fixing block. According to the multi-component-force sensor calibrating machine, the problem that the accuracy of a sensor is easily and directly affected due to the fact that a traditional sensor calibrating machine can produce different micro-strain in other directions when one-way force detection is used is solved, strain produced by the sensor in multiple dimensions can be detected, it is convenient for technicians to compensate or modify force of the senior according to a detection value, and thus the problem of mutual interference among multi-directional force is solved.

Description

technical field [0001] The invention relates to the technical field of sensor calibration tests, in particular to a multi-component force sensor calibration machine. Background technique [0002] Calibration machine is a kind of calibration machine, which mainly refers to the use of standard measuring instruments to test whether the accuracy (precision) of the used instruments meets the standards. Generally, it is mostly used for instruments with high precision. The calibration machine can determine the input-output relationship of the instrument or measurement system, assign the scale value of the instrument or measurement system; determine the static characteristic index of the instrument or measurement system and eliminate the system error, thereby improving the accuracy of the instrument or system. [0003] The sensor calibration machine is mainly to detect whether the accuracy of the sensor meets the standard. The traditional sensor calibration machine uses a unidirecti...
