Abstract

The invention discloses an electro-hydraulic type torque detector. The electro-hydraulic type torque detector comprises a driving device, a hydraulic device and a control device; the hydraulic deviceis connected with the driving device; the hydraulic device provides a driving force for the driving device; the control device is electrically connected with the driving device and the hydraulic device; the control device is used for controlling the operation of the hydraulic device; and the control device is further used for receiving measurement signals from the driving device. The control device is adopted to control the hydraulic device, so that the control device can digitally control the driving device and the hydraulic device, and therefore, control accuracy can be improved; and the hydraulic device is adopted, and the hydraulic device, the control device and the driving device are arranged together, and therefore, the size of the equipment is reduced, and the problem of structuraldispersion is overcome.

Description

technical field [0001] The invention relates to the field of measuring machinery, in particular to an electro-hydraulic torque detector. Background technique [0002] At present, the common torque detection equipment on the market adopts the structure of hydraulic station as the power to drive the tester. However, the hydraulic station has the defects of large volume and scattered structure, and in the existing detector, the method of using the hydraulic station to control the detector is simple hydraulic plus mechanical control, which has the defects of low accuracy of torque parameters and inaccurate rotation angle . Contents of the invention [0003] The object of the present invention is to propose an electro-hydraulic torque detector to achieve the advantage of improving control accuracy in view of the above problems. [0004] To achieve the above object, the present invention provides an electro-hydraulic torque detector, comprising a drive device, a hydraulic devi...
