Embodiment Construction
[0033] Below the specific implementation method, further detailed description of the technical solution of the present invention.
[0034] like figure 1 and figure 2 It shows that a hanging rack micro measuring force calibration device includes the installation basis for adjustable vertical height measurement sensors 2. Activity calibration rack 3 and standing frame 1 for weight -heavy.
[0035] The lower part of the bottom of the testing sensor installation basis 2 is installed on the standing frame 1, which is set to have a force measurement sensor installation platform at the top of the upper part of the upper activity part of the installation basis 2 of the test force sensor.
[0036] In this embodiment, the installation foundation of the force measurement sensor 2 includes the bracket 2-1, the vertical slide 2-2, the sensor seat 2-3, and the extended fixed column 2-4. The 1-1 column 1-1, the vertical slide platform 2-2 is fixed on the bracket 2-1, the sensor seat 2-3 is fixed...

The invention provides a hanger type miniature dynamometer calibration device. The hanger type miniature dynamometer calibration device comprises a force transducer mounting foundation, a movable calibration frame and a vertical frame, the lower part of the force transducer mounting base is mounted on the vertical frame, and the upper part of the force transducer mounting base is provided with a force transducer mounting platform; the movable calibration frame comprises a top hanging bracket, a middle connecting rod and a bottom counterweight frame, the top hanging bracket is movably hung on the vertical frame, and the position, used for mounting a sensor, on the force transducer mounting platform coincides with the gravity center of the top hanging bracket in the vertical direction; a vertical movable hole is formed in the hanging bearing position of the top hanging bracket, so that after the top hanging bracket is jacked up, the movable calibration frame does not make contact with the vertical frame or the force transducer installation base. According to the device, the movable calibration frame is completely separated and is only in contact with the tested force transducer, so that the whole weight of the movable calibration frame can be effectively transmitted to the force transducer, and the problem that the force transmission process is influenced due to the existence of other supporting structures is solved.
Description
Technical field [0001] The present invention involves a calibration device for micro -measurement meter. Specifically, it involves a gravidal micro -measurement force calibration device and a calibration method. Background technique [0002] The calibration work of measuring the force meter is to calibrate the force measurement sensor. The accuracy of the sensor directly determines the accuracy of the measurement meter. [0003] Most of the current measurement of measurement measuring meter measuring meters is too complicated, costs are high, and it is not easy to popularize applications. [0004] The reason is that the capacity of the force is difficult to control. [0005] The commonly used method is to use the weight to calibrate, but it is unknown whether the structure of the conduction will cause losses. [0006] If the application number is: 201220559410.6, the invention name is: the practical new patent of the calibration device of the gas -floating and static micro -measu...
