Method for dealing with displacement failure of universal tension machine

The universal tensioner uses servo motor drive and servo motor, with high rigidity, high precision, high transmission efficiency. The planetary deceleration system drives the ball screw to realize the test loading process. This machine uses an advanced DSP+MCU full digital closed-loop control system for control and measurement, and uses a computer to perform dynamic display of the test process and test curves, and performs data processing. After the test is completed, the test data can be re-analyzed through the graphical processing module to realize secondary editing, with Excel data export and printing of the test report, and the product performance reaches the international advanced level. During the use of the universal tension machine, if the displacement of the universal tension machine fails, it is recommended that you deal with it according to the following methods:

1. First check the displacement sensor, because the universal tensioner system is a closed-loop system. If you want to know which part is a problem, you must cut off the loop in the system to make it an open-loop system. This can determine whether the sensor signal of the test machine is normal. At this time, the feedback signal of the displacement sensor must also be disconnected to make it an open loop. At this time, the workstation sends a signal to control the movement of the actuator and measure the feedback value of the sensor. After several repetitions, the feedback data value of the sensor can form a straight line, which changes linearly, so you can know if there is something wrong with the sensor.

2. The second is to check the amplifier unit of the universal tensioner. After the displacement sensor problem has been ruled out, because the universal tensioner system is a closed-loop system, the normality of the amplifier unit must be checked, and the method is to disconnect the output signal of the amplifier unit. Remove the output wiring, add a DC input signal to the amplifier unit, and then measure the output of the pendulum impact tester amplifier unit. After repeated tests several times, obtain linear change trend data of the output signal of the amplifier unit, so that you can know if there is a problem with the amplifier unit.

3. Finally, check whether the system settings of the universal tensioner are normal. Under normal circumstances, the stroke of the actuator in the workstation should be ±50mm. If it does not match this number, it is a problem with the system setting, and the system needs to be set again. If the display value on the workstation's display panel is still incorrect, it can be determined that only a re-positioning and shifting system can solve this type of problem.
