Description
Technical Field
The utility model relates to the field of mechanical and tribological performance test of various standard components, in particular to an integrated pressure-torsion compound sensor measuring device of a multifunctional bolt fastening analysis system.
Background
The threaded fastener connecting system is most widely applied in the form of a bolt-nut connecting pair, and most of the threaded fastener connecting system is applied under the action of pretightening force, so that the reliability of the bolt connection can be improved, and the tightness and the rigidity of a connected body can be enhanced. In a threaded fastener connection system, when the pre-tightening force is not available or insufficient, the connection cannot be truly performed, which is generally called under-tightening; too high a preload or over-threading can also lead to failure of the threaded connection. Because the pretightening force is difficult to directly measure on the installation site, the pretightening force of the threaded fastener is mostly realized by adopting a means of controlling torque and rotation angle. This requires knowledge of the relationship between torque, rotational angle and preload of the threaded fastener. I.e., torque-clamping force relationship of the threaded fastener.
The relation between the torque and the clamping force of the threaded fastener not only relates to a test and calculation method of the fastening characteristics of a series of threaded connection pairs such as a torque coefficient, a friction coefficient (comprising the thread friction coefficient and a supporting surface friction coefficient), a fastening shaft force, a fastening torque and the like, but also relates to basic terms such as a calculation method of the stress cross section area and the bearing area of the threaded fastener and the like, and the specification of symbols.
The domestic measuring device for analyzing the relation between the torque and the clamping force of the fastener mainly adopts a split type structural form, namely: the dynamic torque sensor, the load sensor and the static torque sensor are separated. The total torque, clamping shaft force, and thread width torque were measured separately. The measuring device with the structure has the advantages of simple design and manufacture and convenient installation, but has larger problems, and the bolt clamping in the test process is time-consuming and labor-consuming, thereby being unfavorable for engineering application. For the integrated pressure-torsion composite measuring device, although relevant units are designed and manufactured abroad, the integrated pressure-torsion composite measuring device has the problems of incomplete specification, high price, long shipment time, incompatibility of an interface and a controller of an instrument manufacturing unit and the like, and greatly restricts the application of the integrated pressure-torsion composite measuring device in the performance test of a fastener.
