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...

Abstract

The invention discloses a torsion test device, which comprises a base, an XY regulating unit, a Z regulating unit, a clamping device and a torsion measuring unit, wherein the clamping device is arranged on the XY regulating unit and can move in the horizontal direction along the XY regulating unit, and the torsion measuring unit is arranged on the Z regulating unit and can move in the vertical direction along with the Z regulating unit. The torsion test device has the advantages that the three-dimensional regulation is adopted, so an object to be measured is preferably matched with the measuring unit, the fault and the danger caused by manual operation are avoided, and the accuracy of measurement results is improved. In addition, because the clamping device has high flexibility, and various measurement requirements can be met.

Description

technical field [0001] The invention relates to a torsion testing device, in particular to a torsion testing device that meets various testing requirements. Background technique [0002] The torque test device is a commonly used instrument in failure analysis and testing projects, which is used to measure the torque of screws, screwdrivers or other mechanical parts. Usually, the method used to measure the torque is: select a suitable bit according to the object to be tested, connect the bit to the shaft of the torque measurement tool, and dock it with the object to be measured, and then manually rotate the object to measure the torque data . [0003] This test method may cause large errors due to the difference in the magnitude and direction of the force applied by the user, or the test cannot be completed due to insufficient pressure. In addition, the user will get tired after rotating the object to be measured for a period of time, and it is not easy to realize batch mea...
