Description
Technical field
The invention belongs to a kind of actuator comprehensive detection system, refer to that the functions such as the measurement of a kind of colleeting comb, measurement of angle, tachometric survey, feedback voltage measurement, linearity measure, load loading are in the automatic all-purpose tester of actuator of computer based of one especially.
Background technology
The checking measurements of actuator series products, be usually included in the current measurement under a fixed load, measurement of angle, tachometric survey, feedback voltage measurement, linearity measure etc., current existing technique is all generally be divided into several station whether qualifiedly to detect separately to judge, efficiency process that is not high and that judge is subject to subjective factor impact.The detection mode of each concrete step is as follows:
The measurement of current actuator electric current, is usually adopted the mode of series winding reometer reading, is arranged on current detecting equipment, is judged the mode that reometer is contacted during measurement by the data on manual read's obtaining current table.Because reometer data are continuous chatterings, in test process, tester must look at surface always, and slightly slack possibility will miss some key values.
The measurement of current actuator angle, mostly adopts the testing tool of scale dribbling pointer, drives indicators turn during the course by actuator, then estimates index dial sense data.The key affecting data accuracy in process is coordinating and the gap error of pointer and index dial and reading error between actuator with pointer.
The tachometric survey of current actuator, more traditional is the time using timer record actuator turns certain angle, then be converted to speed, generally only have a few second because its process time is shorter, use timer larger by the error effect starting and terminate to bring; Existing actuator tachometric survey also has a kind of comparatively advanced mode, be placed in the scope of indicators turn process with two photoelectricity doors, can be recorded by instrument when indicators turn is through the time needed between two photoelectricity doors, then be converted into the rotating speed of actuator, the degree of accuracy of this mode is reliable.
The metering system of the feedback voltage of current actuator and the metering system of electric current similar, adopt the mode of shunt voltage table, be arranged on feedback voltage checkout equipment by the mode of voltage table parallel connection, the data of being got on voltage table by manual read during measurement are judged.Same, because voltage table data are continuous chatterings, in test process, tester must look at surface always, and slightly slack possibility will miss some key values.
The linearity measure of current actuator is adopt to get a mode calculated a bit, the value a little obtaining several angle and feedback voltage is got by said method, again by calculating the linearity, it is slower that this mode gets spot speed, and in order to ensure the accuracy of the linearity, when getting a quantity and increasing, workload is larger, thus causes inefficiency, part company is had to select the linearity automatic measurement system of potentiometer, feedback voltage and the data of the duration of runs directly can be gathered and calculate the linearity by computing machine, linearity automatic measurement system due to potentiometer aims at potentiometer design and produces, in measuring process, drive potentiometer to rotate by stepper motor, by taking the data of time and corresponding feedback voltage, by the cutting edge aligned degree of computer calculate, but there is a drawback when this complete equipment is used in the linearity measure of actuator: stepper motor can ensure it is uniform motion under setting, but existing actuator is generally the direct current generator adopted, its speed can be subject to the impact of voltage and load, especially change greatly in the spot speed started and terminate, so service time and corresponding feedback voltage calculate the accuracy that can not ensure that it is absolute.
