Embodiment:
Below in conjunction with accompanying drawing, the utility model embodiment is described in further details: a kind of hydraulic cylinder displacement transducer accuracy calibration device as shown in Figure 1 comprises guide rail 1, grating scale 2, detecting device 3, adaptive chuck 4, test solution cylinder pressure 5, hydraulic valve platform 6, detects frame 7, low-voltage electrical apparatus unit 8, rack 9, I/O unit 10, industrial computer 11, display 12; Test solution cylinder pressure 5 is connected by oil circuit with hydraulic valve platform 6; Low-voltage electrical apparatus unit 8 is connected by wire with rack 9, I/O unit 10, industrial computer 11, display 12; Guide rail 1, grating scale 2, hydraulic valve platform 6, low-voltage electrical apparatus unit 8 are arranged on and detect on frame 7; Detecting device 3 is arranged on adaptive chuck 4; Adaptive chuck 4 is arranged on the piston rod of test solution cylinder pressure 5; Adaptive chuck 4 is slidably connected with guide rail 1.The utility model adopts the grating scale detection method, when the control of the proportional servo valve on hydraulic valve platform 6 hydraulic cylinder piston rod moves, adaptive chuck 4 synchronizing moving on guide rail 1, be connected in the detecting device 3 raster chis 2 on adaptive chuck 4, detection signal is transferred to industrial computer 11, and the displacement signal that will be arranged on simultaneously the linear displacement transducer output of test solution cylinder pressure 5 bodies also is input to industrial computer 11.Industrial computer 11 softwares will be set the given signal of stroke L0() the stroke L1(feedback signal that detects with linear displacement transducer) compare, utilize deviation signal to control, finally make stroke L1 with the deviation of setting stroke L0 in the accuracy of detection scope.The stroke L2 that stroke L1 and grating scale 2 are detected contrasts, and can draw the drift correction amount of test solution cylinder pressure 5 body sensors stroke detection value L1.The core of industrial computer 11 softwares is adjustment modules.Its principle is: for any one, set stroke L0, the given little deviation stroke LS of system and control accuracy EPS.As the large (> LS of deviation) time, the P(ratio) the I(integration) regulate and all work, but be mainly the P(ratio) regulate, this moment, system responses was very fast, and adjustment module provides larger opening, makes hydraulic cylinder high speed, high thrust operation; When deviation less (<LS) time, P regulates and stops, and only has the I(integration), regulate and work, this moment, adjustment module provided less aperture, made hydraulic cylinder low speed, low thrust operation.As long as deviation is greater than given accuracy EPS, integral adjustment is just always in running order, in case deviation, less than given accuracy, is regulated and finished.In the hydraulic cylinder process, detecting device in real time, accurately detects the displacement of hydraulic cylinder by the raster chi, and this detected value is by the industrial computer continuous recording but do not participate in controlling.Therefore grating scale and detecting device are to be independent of the interior linear displacement transducer of hydraulic cylinder and the detecting element of displacement controlling and regulating system, its testing result is used for the displacement accuracy of final decision hydraulic cylinder under body displacement transducer testing conditions, thereby realizes the purpose of calibration bits displacement sensor itself.
