Driver torque test system and method

Abstract

The invention discloses a driver torque testing system and method. The system comprises a supporting assembly, a mounting assembly, a connecting frame, a tilt angle sensor, a torque sensor, a driving motor and a control device. When testing is started, the control module controls the driving motor to act, the torque sensor is made to rotate, the connecting frame is driven to rotate, and therefore the center shaft of the driver is driven to rotate; the tilt angle sensor and the torque sensor have the same sampling period, and the tilt angle sensor and the torque sensor synchronously collect a tilt angle value and a torque value every other sampling period and feed the tilt angle value and the torque value back to the control module; when the inclination angle value reaches the maximum inclination angle, the test is stopped, and the control module obtains a series of inclination angle values and corresponding torque values, generates an inclination angle-torque relation curve and displays the inclination angle-torque relation curve on the display module; the system and the method have the advantages of being high in testing precision, convenient to operate, high in automation degree, high in testing efficiency, convenient to replace and maintain and the like.

Description

technical field [0001] The invention belongs to the technical field of aviation driver torque testing, and in particular relates to a driver torque testing system and method. Background technique [0002] A driver commonly used in aviation products generally consists of a sleeve, drive lugs on the top and bottom of the sleeve, a torsion spring inserted inside the sleeve, and a central shaft passing through the torsion spring. Usually, it is necessary to determine the correlation between the angle value of the driver and the torque value, and draw the angle-torque relationship curve. [0003] The existing method is: install the driver on a special tooling with a dial, apply a load within the set range to the driving lug of the driver through a torque wrench; the driving lug rotates around the central axis, and the dial shows Angle value, the torque wrench can display the torque value; the operator collects multiple sets of angle values ​​and corresponding torque values ​​to ...
