Problems solved by technology

[0004] The existing constant load rings do not have the ability to monitor the looseness of bolts. Under certain normal working conditions, due to the impact of equipment vibration, the tension of bolts is lower than the rated value. To a certain extent, it can continue to be used without immediate maintenance.

Abstract

The invention discloses a bolt tightness intelligent detection piece which comprises a first pressure-bearing piece, a second pressure-bearing piece and a supporting piece which are all provided with bolt holes, the supporting piece is located between the first pressure-bearing piece and the second pressure-bearing piece, and the bolt holes in the first pressure-bearing piece, the second pressure-bearing piece and the supporting piece are right opposite to each other. A plurality of contact detection switch pieces with different heights are installed between the first pressure bearing piece and the second pressure bearing piece, gaps are reserved between the extending ends of the contact detection switch pieces and the inner surface of the first pressure bearing piece, and the contact detection switch pieces are all connected with an alarm device. Switching pieces under different loads can be arranged according to needs, relevant alarm prompt information is sent out at the same time, management personnel can carry out maintenance or non-maintenance treatment according to the information, maintenance personnel can also overhaul loose bolts as soon as possible, effectiveness and safety of bolt connection are ensured, and the detection mode is low in cost and reliable in detection.

Description

technical field [0001] The invention relates to the technical field of bolt connection reliability detection devices, in particular to an intelligent detection part for bolt tightness. Background technique [0002] In the production stage, proper bolt preload is the prerequisite to ensure the reliability, tightness and rigidity of the connection. Excessively high or too low pre-tightening force is likely to cause damage to the equipment. Accurately determining the pre-tightening force of bolts is one of the key issues in the manufacturing industry. Traditional equipment installation (such as automobile engine assembly) mostly uses torque wrench to control the tightening torque to achieve the predetermined bolt pre-tightening force. However, the actual pre-tightening force is closely related to the contact surface roughness, friction coefficient, lubrication and other factors. Research shows that through The error of the bolt pretightening force controlled by the torque wren...
