The load sensor calibrating device has the advantages of having simple structure and being convenient for installation and detachment, realizing tensioning and pressing bidirectional load calibration for the load sensor simultaneously, reducing error caused by mismatching, increasing calibration precision, greatly shortening calibration time and lowering expense.
Description
Technical field
The utility model relates to a kind of calibrating installation, is specifically related to a kind of load transducer calibrating installation.
Background technology
In aeromotor and the strength test of Helicopter Transmission System component structural, the precision of load measurement is the basis of multichannel harmony loading control system precision, and the precision of load transducer is to be directly connected to accuracy of experimental results and reliability.Routinely, load transducer send metrological service to demarcate, and at metrological service's timing signal, the excitation of load transducer is provided by special reference power supply, and signal output enters special display device reading.For multichannel harmony loading control system, the excitation of load transducer is provided by controller, output also enters controller, this is with different in the situation of metrological service's timing signal, if the parameter that provides when the direct input calibration of controller then might cause occurring because of the different errors that produce of system matches.In addition at metrological service's timing signal, can not apply simultaneously draw, compressive load, need twice mounting or dismounting load transducer just can finish calibration operation, the alignment time is long, error is big.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to use, and the alignment time, error is little, the load transducer calibrating installation that calibration accuracy is high.
Load transducer calibrating installation of the present utility model comprises closed frame, load transducer, controller and secondary instrument, it is characterized in that: the upper end of described closed frame is provided with connecting screw rod, loading position-arresting disk, the loading positioning disk that band loads swivel nut, and is fixed tightly on the closed frame by fastening bolt; Described connecting screw rod connects upper joint bearing, normal loading sensor, load transducer successively and is fixed on the hypozygal bearing of closed frame lower end; Load transducer is connected with controller, and the normal loading sensor is connected with secondary instrument.
The utility model has the advantages that simple in structure, easy installation and removal, that realizes load transducer simultaneously draws, presses the calibration of two-way load, has reduced the error that does not match and produce, and has improved calibration accuracy, has shortened alignment time and expense greatly.
