Abstract

The invention provides an inspecting device of drawing force of a driving shaft. A fixing tool is arranged through a transportation track, so that fast material charging and discharging is realized. After the driving shaft is fixed by the fixing tool, a push-down cylinder starts to push downwards to enable a left clamping arm and a right clamping arm, together with the fixing tool, to well clamp the driving shaft. A push-right cylinder starts to push rightwards; the driving shaft starts to draw towards two sides; and then the push-right cylinder becomes loose. Contraction-back force of the driving shaft can be instantly sensed via a drawing force sensor, so that the drawing force can be detected. According to the invention, after materials are fast charged, the drawing force of the driving shaft can be accurately inspected; the efficiency is high; the inspection is precise, and the inspecting device is suitable for production.
