Independent weight loading-unloading dead-load type torque measurement device

Abstract

The invention discloses an independent weight loading-unloading dead-load type torque measurement device, and belongs to the technical field of measuring testing. The independent weight loading-unloading dead-load type torque measurement device aims at solving the problems that in the prior art, the loading speed is low, a control device is complex, operation is difficult to achieve, and automation is difficult to achieve. The independent weight loading-unloading dead-load type torque measurement device comprises a supporting device, a loading device, a torque installation part, a leveling device and automatic loading devices, wherein the loading device is fixed on the upper surface of the supporting device, the torque installation part is connected with a guide rail sliding block and a nut supporting base of the loading device, the leveling device is connected with the other end of a long shaft of the torque installation part, and the automatic loading devices are fixed at the two ends of the leveling device. The automatic loading devices are characterized in that eccentric wheels are driven by stepping motors B to perform rotational motion, trays are driven by the eccentric wheels to perform linear lifting, and therefore automatic loading and automatic unloading of weights are achieved. According to the independent weight loading-unloading dead-load type torque measurement device, the eccentric wheels are driven by the stepping motors B to perform the rotational motion to achieve the automatic loading and the automatic unloading of the weights with any number, measurement on different torque values is accordingly achieved, and the motor driving structure is simple.
