Abstract

The invention discloses a portable torque wrench online detection device. The portable torque wrench online detection device comprises a box body and a torque wrench detection device; the torque wrench detection device comprises a fixed outer sleeve and a rotary inner sleeve assembly, an elastic assembly is arranged in the rotary inner sleeve assembly, and a rotary lifting assembly is assembled at the top end of the rotary inner sleeve assembly in a threaded mode; and a lifting loading mechanism is arranged below the elastic assembly, a torque sensor is arranged in the lifting loading mechanism, and torque transmission assemblies are assembled in the rotary inner sleeve assembly and the lifting loading mechanism in an up-down sliding mode. According to the invention, the torque sensor is arranged in the lifting loading mechanism, the torque of the rotary lifting assembly is transmitted to the torque sensor through the torque transmission assemblies, and the torque sensor does not transmit force, so that the lifting loading mechanism does not affect the torque sensor when loading the elastic assembly; therefore, the torque sensor does not need to be mounted and dismounted during torque detection, and the detection is 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...
