Torsion testing device for torsional spring

The invention provides a torsion measuring device for a torsional spring. The torsion measuring device comprises a supporting member, a torsional spring twisting end member and a torsional spring fixing end member and is characterized in that the torsional spring twisting end member comprises a fixing plate, a steering plate, a pivoted arm and a movable clamping plate; the steering plate and the pivoted arm are used for determining a twist angle; and the movable clamping plate and the pivoted arm are used for clamping a torsional spring twisting end. Due to the design of a new torsional spring twisting end clamping mode, the torque and dynamic impulsive torque of the torsional spring can be measured at different twist angles; moreover, a bench clamp can be taken as the supporting member of the device; and the torsion measuring device has the characteristics of convenience for using and low cost, and can be used widely.
