AI Technical Summary

Technical Problem

Existing torque wrenches have the problems of narrow application range, high cost and inconvenient operation, especially when measuring nuts of different sizes, they cannot effectively clamp and automatically adjust.

Method used

A nut locking torque measuring device was designed, which included a clamping assembly, a one-way locking assembly and a driving assembly. The automatic clamping and automatic adjustment of nuts of different types were achieved through limit blocks and elastic parts. The driving assembly was used to drive the mounting base to move and rotate, and the locking torque was measured in real time in combination with the torque measuring assembly.

Benefits of technology

It achieves wide applicability to nuts of different models, reduces costs, reduces the manual alignment process through automatic adjustment, and improves the convenience of operation and the accuracy of measurement.

Abstract

The invention discloses a nut locking torque measuring device and method, and the device comprises a bottom plate, a torque measuring assembly, a clamping assembly, a one-way locking assembly and a driving assembly, the top of the torque measuring assembly is provided with a measuring end, the measuring end is detachably connected with a mounting part, and the clamping assembly comprises a mounting seat. Two clamping parts which are oppositely arranged are movably connected to the mounting seat, clamping surfaces are arranged on the two clamping parts, limiting blocks are arranged on the two clamping surfaces, the two sets of one-way locking assemblies are arranged on the mounting seat and used for locking the two clamping parts respectively, and the driving assembly is movably connected with the mounting seat. A first elastic piece is arranged between the driving assembly and the mounting base, and the driving assembly is used for driving the mounting base to move in the vertical direction and driving the mounting base to rotate. The torque wrench aims at solving the technical problems that a torque wrench is narrow in application range, high in cost and inconvenient to align and operate.
