Provided is a system for measuring performance indexes of an inductive sensor. The system comprises a measuring platform, a sensor assembly, a sensor position adjusting device and a micro-motion system, wherein the sensor assembly comprises at least one sensor, a sensor measuring arm and a sensor measuring head arranged on the sensor measuring arm; the sensor position adjusting device is used for adjusting the sensor measuring head or adjusting the position of a measuring head of an inner diameter measuring arm assembly so that the sensor measuring head is kept to make contact with the measuring head of the inner diameter measuring arm assembly till the output value of the sensor is zero, and then the sensor measuring head and the measuring head of the inner diameter measuring arm assembly are locked; the micro-motion system at least comprises a micro-motion system actuator. The micro-motion system actuator at least comprises the inner diameter measuring arm assembly, an object bearing platform, a guide rail and a grating ruler, wherein the inner diameter measuring arm assembly is fixed to the object bearing platform, when the object bearing platform moves, the inner diameter measuring arm assembly can move together with the object bearing platform so that the sensor measuring head can move along with the inner diameter measuring arm assembly, and the displacement direction and the displacement of the object bearing platform are measured through the grating ruler.
Description
technical field [0001] The invention relates to a measuring system for the performance index of an inductive sensor, which is suitable for all inductive sensors used for machining and measuring the size of workpieces. Background technique [0002] At present, the measurement methods for domestic repair and inspection of inductive sensors are all in the manual and static measurement stage. There are several problems in the use of this measurement method: (a) there may be errors in the actual mechanical measurement position; (b) low efficiency; (c) it cannot simulate the actual situation in the process of machine tool processing, that is, the dynamic response cannot be measured; (d) It is difficult to measure the linearity within the range; (e) the working range of adjusting the sensitivity is not wide enough (for example, M company can only be within ±100μ); (f) the repeatability measurement is difficult. [0003] In order to overcome the deficiencies of the existing technol...
