Portable torque wrench online detection device

Abstract

The invention discloses a portable torque wrench online detection device, comprising a box body and a torque wrench detection device; the torque wrench detection device comprises a fixed outer sleeve and a rotating inner sleeve assembly, and an elastic assembly is arranged inside the rotating inner sleeve assembly, The top end of the rotating inner sleeve assembly is threadedly equipped with a rotating lifting assembly; a lifting loading mechanism is arranged below the elastic assembly, a torque sensor is arranged inside the lifting loading mechanism, and the inner parts of the rotating inner sleeve assembly and the lifting loading mechanism slide up and down Equipped with torque transfer components. In the present invention, the torque sensor is arranged inside the lifting and loading mechanism, and the torque of the rotating lifting assembly is transmitted to the torque sensor through the torque transmission component, and the torque sensor transmits torque but not force, and the lifting and loading mechanism does not load the elastic component. It affects the torque sensor, so there is no need to install and remove the torque sensor during torque detection, and the detection is very convenient.

Description

technical field [0001] The invention relates to the technical field of torque wrench detection devices, and more particularly relates to a portable online detection device for torque wrench. Background technique [0002] Torque wrenches are widely used in assembly and maintenance of mechanical engineering to operate fastened or loosened threaded fasteners, such as bolt and nut connections. For high-precision machinery, threaded fasteners must be tightened or loosened according to a prescribed operating procedure at a preset level of torque. Improper manual operating torque may inadvertently cause damage or destruction of threaded fasteners or threaded holes, and thus may result in damage to machine functionality and operational accuracy. During the long-term frequent use of the torque wrench, the preset torque value may change, and the torque wrench needs to be checked and calibrated regularly through the torque wrench detection device. [0003] The Chinese invention paten...
