Abstract:
1. A torque testing device, comprising: a base comprising a top surface and a bottom surface opposite to the top surface; a clamping device mounted on the top surface for clamping a fastener; a holding cylinder mounted on the top surface; a mounting beam mounted on the holding cylinder and spaced apart from the clamping device, the mounting beam defining a first nesting hole substantially perpendicular to the top surface; a moving component comprising a tubular member and a driving component, the tubular member being received in the first nesting hole, the driving component mounted on the mounting beam and configured for driving the tubular member to move along an axial direction of the first nesting hole; a rotation component comprising a rotation shaft and at least one rotation element, the rotation shaft being received in the tubular member, the rotation shaft capable of being moved with the tubular member such that one end of the rotation shaft is connected to the fastener, the at least one rotation element being positioned between the rotation shaft and the tubular member, the rotation shaft capable of being rotated about the tubular member through the at least one rotation element; and a torque wrench connected to the other end of the rotation shaft, the torque wrench being configured for providing a torque to the rotation shaft and revealing a value of the torque.
