Problems solved by technology

At present, there is no direct measurement method for the pressure in the bolt connection, and the pretightening force borne by the bolt and the force between the devices can reflect the assembly quality and reliability of the entire device, so the pretightening force and the force exerted by the bolt are measured by the bolt It is extremely necessary to be stressed by the connected instrument

Abstract

The invention discloses a bolt structure capable of measuring pressure and pressure intensity in real time. The bolt structure comprises a force measuring bolt, a pressure measuring module, a wirelesstransmission module, a single-chip microcomputer module and a data display module. The force measuring bolt comprises a bolt head part and a bolt rod part. The bolt head part and the bolt rod part are provided with through wire through holes. The bolt rod part is provided with a plurality of patch grooves at intervals along the axial direction. The pressure measuring module comprises a head forcemeasuring unit and a rod force measuring unit. The head force measuring unit comprises a gasket. A micro force sensor array is arranged on the gasket. The rod force measuring unit comprises a plurality of strain gauges, and the strain gauges are arranged in the patch grooves. According to the invention, the head of the bolt adopts a miniature force sensor array; the rod part of the bolt adopts strain gauge bridges arranged in the patch grooves, and the other parts of the rod part of the bolt except the patch grooves adopt fastening threads; the two are effectively combined, and the functionsof connection and force measurement are achieved; the accuracy of force measurement can be guaranteed; and low cost can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical and electrical engineering, and in particular relates to a bolt structure capable of real-time measurement of pressure and pressure. Background technique [0002] Bolt (or screw) group connection is one of the most commonly used connection methods in the assembly of electromechanical products such as instruments and meters. For the pressure measurement after the assembly of electromechanical products, the traditional resistance strain test method is used to attach the strain gauge to the bolt screw, which is easy to ignore. The bolt head part is affected by the force, or the force is measured with a special force measuring instrument, which increases the energy and material force. [0003] Pressure measurement during instrument assembly is becoming more and more common in today's networked digital age. At present, there is no direct measurement method for the pressure in the bolt connection, a...
