Description

technical field [0001] The invention relates to the field of torque measurement, in particular to a spring tube torque measurement device and a test method thereof. Background technique [0002] The torque measuring device in the prior art mainly includes a strain gauge sensor and a torsion bar. The method for measuring the torque by using the measuring device is: if it is necessary to measure the static torque, one end of the torsion bar is connected with the tested piece and placed on the tested piece. Rotate under the drive of the torsion bar, and the other end is fixed, so that the small deformation of the torsion bar under the action of the input torque is measured by the strain sensor, and the torque value is measured through signal conversion; if it is necessary to measure the dynamic torque, connect one end of the torsion bar with the measured The parts are connected and rotated under the drive of the input torque, and the other end rotates freely, so the torque valu...

Problems solved by technology

[0003] The patent document CN101639392 discloses a torque measuring device of a non-inserting shaft torque measuring device and a method for measuring torque using the measuring device. The above-mentioned solution has the following technical problems: since it is necessary to measure the deformation of the torsion bar to Indirect measurement of torque value, if the input torque value exceeds the measurement range, it is easy to twist the torsion bar and damage the torque measurement device; if the input torque is too small, it is difficult to deform the torsion bar sensitively, thus affecting the torque measurement Sensitivity and precision of the device

[0004] However, due to the different types and specifications of the spring tubes, and the torque of the spring tubes under different angles is also different, the current conventional torque measuring tool is not universal for spring tubes of different specifications, so the spring tubes of different specifications and models are measured. It is necessary to replace the corresponding tooling from time to time, the work efficiency is low, the economic benefit is poor, and resources are wasted
