The invention discloses an annular-structure connecting bolt pre-tightening force detecting system which comprises a base, a linear movement device, a plurality of measuring devices and a plurality ofcorresponding adjusting devices. A guide rail groove is formed in the base. The linear movement device is movably installed in the guide rail groove in the base and used for installing the measuringdevices and the adjusting devices and can move in the direction of the guide rail groove. Each measuring device is movably connected to and installed on the corresponding linear movement device through a measurement support. Each measurement support is connected with a measurement rack. The measurement racks of the measuring devices act together and are used for fixing a tested piece. Pressure sensors are arranged at the positions, corresponding to the tested piece, of the measurement racks and used for detecting the screwing pre-tightening force of the tested piece. Thrust devices of the adjusting devices are connected with the measurement supports and push the measurement supports for fine adjustment, and therefore the measurement supports of the measuring devices are pushed to meet thesize requirement of the tested piece.
Description
technical field [0001] The invention belongs to the technical field of bolt pretightening force detection, in particular to a ring structure connecting bolt pretightening force detection system. Background technique [0002] Bolt connection is the main assembly scheme of construction machinery. Due to the complex construction environment and harsh working conditions of construction machinery, the requirements for bolt pre-tightening force are relatively high in the production process and after-sales service process of construction machinery. When the bolts are fastened, the bolt pretightening force is required to meet the design requirements, especially the bolt pretightening force requirements for ring structure connections are high and the dispersion is low, so as to ensure the reliability and stability of the bolted connection during the long-term operation of construction machinery. [0003] Therefore, in the production process and after-sales service of construction ma...
