Problems solved by technology
However, the superimposed force standard machine is heavily dependent on the standard sensor used. The standard sensor is unstable when measuring a small range, and the measurement accuracy is low. In order to solve this problem, the current method is to replace the standard sensor with a small range during the measurement process. This is not only cumbersome to operate, it is impossible to measure continuously

The invention discloses a bidirectional force testing device including a support including a support base, a support column, and a support upper beam, a reverse rack, a large electric cylinder arranged on the support upper beam, a connecting rack arranged at the output end of the large electric cylinder, a small electric cylinder arranged in the connecting rack, a large sensor, and a small sensor, the reverse rack includes a reverse rack lower beam, a reverse rack column, and a reverse rack upper beam, a connecting tray is arranged between the large sensor and the connecting rack, and a guide tray is arranged between the small sensor and the small electric cylinder. The small electric cylinder drives the guide tray to move upwards, the small sensor moves upwards to apply a loading force to the connecting tray to measure small measuring range, the large electric cylinder drives the connecting rack to move upwards to apply a loading force to the connecting tray to measure large measuring range, the small sensor guarantees the stability of small measuring range testing and improves the testing precision, and the reverse rack realizes the measurement of the pulling direction and the pressing direction. Compared with the hydraulic testing in the prior art, oil leakage can be prevented, only electric energy is consumed, and the energy consumption is low.
Description
technical field [0001] The invention belongs to the field of force value measurement, and in particular relates to a two-way force value test device. Background technique [0002] Force value detection is an important part of mechanical measurement and testing, and is widely used in national production and life. In the prior art, a standard force sensor with higher accuracy than the verified dynamometer is used as a standard during the test, connected in series with the calibrated / verified force sensor, and loaded in a hydraulic or mechanical way; due to its cost Low cost and high work efficiency, it has been widely used in the mechanical performance testing of various load cells, force sensors, and dynamometers in recent years. However, the superimposed force standard machine is heavily dependent on the standard sensor used. The standard sensor is unstable when measuring a small range, and the measurement accuracy is low. In order to solve this problem, the current method ...
