Abstract

The invention relates to a control system of an automatic hydraulic torque wrench testing device. The control system comprises a detecting system monitoring upper computer, a detecting system PLC (programmable logic controller), a detecting device torque sensor, a hydraulic pump station pressure sensor, a hydraulic pump station servo motor and an emergency stop button. By a hydrodynamic wrench testing device control system, automatic hydraulic wrench testing is realized, influences caused by human factors to hydraulic wrenches are avoided, and accordingly detecting efficiency and detecting precision of the hydraulic wrenches are improved.

Description

technical field [0001] The invention relates to a control system of an automatic hydraulic torque wrench testing device, which belongs to the technical field of digital control. Background technique [0002] At present, the detection of hydraulic torque wrench mainly adopts the method of manually adjusting the relief valve of the hydraulic pump station to control the pressure input pressure of the wrench, and at the same time manually enter the torque value generated by the pressure plate wrench, and use the calculation software to calculate in the computer, and judge the hydraulic wrench according to the corresponding standards Whether the accuracy is qualified. During the entire test process, the pressure control and torque value entry of the pumping station are all done manually, and manual errors and mistakes have a great impact on the test results. In order to reduce the unnecessary impact of human factors on the detection accuracy of hydraulic wrench. It is very mean...
