Abstract

The invention discloses an axial force measuring bolt structure and a measuring method, and belongs to the technical field of mechanical parts. The axial force measuring bolt structure comprises: a bolt body, wherein the bolt body comprises a bolt head and a bolt bar, and the bolt rod is vertically connected to the bolt head; and a strain measuring piece mounted on the bolt bar and used for beingconnected with a strain acquisition device and transmitting a strain signal generated by the strain acquisition device under the changed axial force of the bolt bar to the strain acquisition device, wherein the bolt bar is subjected to strain in the axial direction under the action of changed axial force, the strain measurement part and the bolt rod are subjected to the same changed axial force, the strain measurement part is subjected to strain to generate a strain signal, and the strain measuring piece transmits the generated strain signal to the strain acquisition device. According to the axial force measuring bolt structure, the axial force borne by the bolt body can be measured, and the safety of fixed connection of the bolt body and the separation structure is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to an axial force measuring bolt structure and a measuring method. Background technique [0002] Bolts are widely used in various equipment and structures, and they can fix the separation structure; however, during use, due to factors such as vibration and load bearing of the separation structure, sometimes the bolts will loosen and break, resulting in The separation structure is unstable or even fails. In addition, the tightening effect of bolts mainly depends on their axial force. Loosening or breaking of bolts will lead to changes in axial force. Therefore, axial force measurement plays an important role in monitoring structural stress and bolt status. Therefore, there is an urgent need for a bolt structure capable of measuring the axial force of the bolt and improving the safety of the bolt firmly connected to the separation structure.
