Problems solved by technology
[0002] In the past, the calibration of the coaxiality of the material testing machine used the geometric coaxiality method, such as the weight centering method and the optical measurement method. The disadvantage of this method is that it cannot completely simulate the state of the sample test, and does not consider the force of the connecting tooling. Therefore, the American Standard ASTM E1012 "Standard Practice for Verification of Testing Frame and Specimen Alignment Under Tensile and Compressive AxialForce Application" requires that the material testing machine should be calibrated for the coaxiality of the force

The invention discloses a detection device used for detecting a material testing machine coaxiality calibration sensor. The detection device comprises a crossbeam, a base, a column, a hanger, a mobile crossbeam, a first transmission lead screw, a second transmission lead screw and multiple counterweights. A motor is arranged on the crossbeam. The output end of the motor is connected with the upper end of the first transmission lead screw and the upper end of the second transmission lead screw. The lower end of the first transmission lead screw penetrates through one end of the crossbeam and one end of the mobile crossbeam in turn to be flexibly connected on the base. The lower end of the second transmission lead screw penetrates through one end of the crossbeam and one end of the mobile crossbeam in turn to be flexibly connected on the base. A lead screw nut mechanism is formed between the first transmission lead screw and the mobile crossbeam and a lead screw nut mechanism is formed between the second transmission lead screw and the mobile crossbeam. The upper end of a coaxiality calibration sensor to be detected is connected with the mobile crossbeam. The upper end of the hanger is connected with the lower end of the coaxiality calibration sensor to be detected. The lower end of the hanger penetrates through the base to be connected with the counterweights. The device can realize performance detection of the coaxiality calibration sensor.

technical field [0001] The invention belongs to the field of sensor detection and relates to a detection device for detecting the coaxiality calibration sensor of a material testing machine. Background technique [0002] In the past, the calibration of the coaxiality of the material testing machine used the geometric coaxiality method, such as the weight centering method and the optical measurement method. The disadvantage of this method is that it cannot completely simulate the state of the sample test, and does not consider the force of the connecting tooling. Therefore, the American Standard ASTM E1012 "Standard Practice for Verification of Testing Frame and Specimen Alignment Under Tensile and Compressive AxialForce Application" requires that the material testing machine should be calibrated for the coaxiality of the force. The specification stipulates that the coaxiality calibration sensor of the material testing machine is a strain sensor, which is attached to the uppe...
