Background technology
Rod-pulling type linear movement pick-up has that range ability is large, output accuracy is high and be simple and easy to the features such as use, can be used for measuring the parameter such as displacement, Distance geometry dependent variable, in industry field widespread uses such as electric power, water conservancy, building, Aero-Space and road and rail traffic.
In order to ensure measuring accuracy and the reliability of rod-pulling type linear movement pick-up, need to do periodic calibration to sensor, during calibration, measuring staff and the motion platform of linear movement pick-up are connected, and move linearly with the standard displacement of setting with motion platform, determine the parameters such as its nonlinearity erron, hysterisis error and fundamental error according to the output of linear movement pick-up, thus realize the calibration of linear movement pick-up.
To use and in the process of calibrating at linear movement pick-up, because the direction of measuring staff pull-out and the rectilinear movement direction of motion platform inevitably exist deviation, linear movement pick-up particularly for wide range may cause the flexural deformation of measuring staff even stuck, causes the damage of sensor.Meanwhile, when calibrating the linear movement pick-up of different model, due to the change of sensor physical dimension, require that the position between motion platform and measuring staff adjusts.In existing apparatus, lack and a kind ofly can ensure that measuring staff in calibration process can the device of smooth and easy pull-out in range ability.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of flexible connecting device for the calibration of rod-pulling type linear movement pick-up, be specially adapted in the linear movement pick-up calibration process of wide range, realize different model linear movement pick-up measuring staff and moving platform position adjusts and the smooth and easy pull-out of measuring staff in calibration process, the coaxiality error of measuring staff and connecting link in moving process can be compensated like this, ensure that linear movement pick-up completes smoothly in use and calibration process, not only increase work efficiency but also reduce sensor degradation probability.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of flexible connecting device for the calibration of rod-pulling type linear movement pick-up, comprise measuring staff, linear motion platform and connecting link, linear motion platform is fixedly connected with V-block, connecting link is connected with in the groove of V-block, connecting link and measuring staff are in same level, flexible clutch and adapter is provided with above linear motion platform, adapter one end is flexibly connected with measuring staff, the other end is flexibly connected with flexible clutch, and flexible clutch outer circumference surface is provided with spiral groove.
