Problems solved by technology
However, this method has the following defects: it can only calibrate the tensile force value, but cannot calibrate the compressive force value; when using the ordinary hanging weight method to calibrate, the quality of the weight is limited, and the manual operation is labor-intensive and stable. Poor performance and safety; due to manual lifting, the applicable range is small, and it is not suitable for push-pull dynamometers with large values; when the push-pull dynamometer is calibrated, the verticality adjustment is judged by human eyes, and the accuracy is not high

The invention provides an auxiliary calibration device of a push-pull gauge. The device comprises an L-shaped connection plate and a connection joint, wherein the L-shaped connection plate comprises a mounting part formed by the long sides of the L-shaped connection plate and used for dismantling / mounting the push-pull gauge and a connection part formed by the short sides of the L-shaped connection plate; and the connection joint is detachably mounted on the connection part and used for connecting the connection plate to a force applying device. By adopting the auxiliary calibration device of the push-pull gauge provided by the invention, a standard force applying device can be used for the pulling and pressing calibration when calibrating the push-pull gauge, wherein when in calibration of the pulling force, a force balance adjusting device is also arranged on the connection plate so as to adjust the verticality of the push-pull gauge in the calibration process and realize relatively accurate calibration.
Description
technical field [0001] The invention relates to a calibration device, in particular to an auxiliary calibration device for a push-pull force gauge. Background technique [0002] At present, hand-held push-pull dynamometers are widely used to test engine hatches, steering rods, landing gear, etc., and the accuracy of hand-held push-pull dynamometers directly affects the accuracy and reliability of test data. For the calibration of the push-pull dynamometer, the commonly used method is the hanging weight method, that is, after hanging the weight at the bottom of the push-pull dynamometer, use human power to pull the calibration. However, this method has the following defects: only the tensile force value can be calibrated, and the compressive force value cannot be calibrated; when the ordinary hanging weight method is used for calibration, the quality of the weight is limited, and the manual operation is labor-intensive and stable. Poor performance and safety; due to manual l...
