Integrated type pressing-twisting compound sensor measuring device for multifunctional bolt fastening analysis system

Abstract

The invention relates to an integrated type pressing-twisting compound sensor measuring device for a multifunctional bolt fastening analysis system. The integrated type pressing-twisting compound sensor measuring device comprises a base plate, a vertical mounting plate, a load sensor, an automatic centering roller bearing, a disc type static torque sensor, a bearing sleeve, a locking sleeve, a long locking pin, a circular washer, a locking ferrule, a sealing ring, a positioning pin, an external stop plate, a stop plate, a bolt gasket, a bolt and a short locking pin. According to the invention, the integration of a pressure load sensor and a plate type torque sensor can be realized, so that the pressing-twisting compound sensor relying on import in the long term, high cost, limited size and long supply period can be replaced. A split type sensor set can be replaced, so that the quantity of the test clamps can be greatly reduced and the operation is more convenient.

Description

technical field [0001] The invention relates to the field of mechanical and tribological performance testing of various standard parts, in particular to an integrated pressure-torsion composite sensor measuring device of a multifunctional bolt fastening analysis system. Background technique [0002] The most widely used threaded fastener connection system is the form of bolt-nut connection pair, most of which are used under the action of pre-tightening force. The connection under pre-tightening force can improve the reliability of bolt connection and enhance the tightness of the connected body and stiffness. In the threaded fastener connection system, when there is no pretightening force or the pretightening force is not enough, the real connection effect cannot be achieved, which is generally called undertightening; but too high pretightening force or overtightening can also lead to threaded connection s failure. Since it is difficult to directly measure the pre-tightenin...

AI Technical Summary

Problems solved by technology

The measuring device with this structure has the advantages of simple design and manufacture, and convenient installation, but there are big problems. The bolt clamping in the test process is time-consuming and laborious, which is not conducive to engineering applications.

For the integrated compression-torsion compound measuring device, although there are relevant foreign units to design and manufacture, the problems of incomplete specifications, high price, long purchase time, incompatibility of the interface with the controller of the instrument manufacturing unit, etc., greatly restrict the integrated compression. —Application of torsion compound measuring device in performance testing of fasteners
