Embodiment Construction
[0017] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0018] Such as figure 1 As shown, a torsion testing device includes a base 11, a clamping device 6, a torsion measurement unit, an XY adjustment unit 7 and a Z adjustment unit. The clamping device is arranged on the XY adjustment unit 7 for clamping the object to be tested; the torque measurement unit is arranged on the Z adjustment unit, and the torque measurement unit includes a bit connector 15 , a torque meter joint 12 and a transmission shaft 5 . Such as image 3 The shown bearing 13 uses a deep groove ball bearing, and the transmission shaft 5 adopts an interference fit sleeve on the deep groove ball bearing. There is a gap 14 between 5 and the fine-tuning nut 4, and when the transmission shaft rotates, it will not rub against the fine-tuning nut 4, which improves the accuracy of the experiment. A square mouth is set on the upper end of the transmiss...
