High-precision universal torque loading device and method

Abstract

The invention provides a high-precision universal torque loading device and method, and solves the problem that a torque analysis result is influenced by inevitable introduction of mechanical values like stretching, compression and bending of an existing torque applying device. The device comprises a base, a lower bottom sliding rail, a lower bottom clamping piece, a stand column assembly, an upper beam, a steering sleeve, a torque wrench and a positioning block. The lower bottom sliding rail is in sliding connection with the base and can slide and be positioned on the base in the X direction;the lower bottom clamping piece is connected with the lower bottom sliding rail in a sliding mode and can slide and be positioned on the lower bottom sliding rail in the y direction. The stand columnassembly can stretch out and draw back in the z-direction and be positioned. The two ends of the stand column assembly are fixedly connected with the base and the upper beam. In the torque loading process, by adjusting the position of the lower bottom clamping piece in the X-Y direction, bending factors caused by deviation of a measured piece in the vertical direction in the machining or using process are prevented. A new torque loading thought can be provided for most objects needing torque loading, and a reliable technical guarantee is provided for product development.

Description

technical field [0001] The invention belongs to the technical field of precise torque loading, and specifically relates to a precise torque loading device and method for columnar objects with the characteristics of wide applicability, simple structure, firmness and low manufacturing cost. Background technique [0002] With the implementation of major aerospace engineering tasks such as space stations, lunar exploration missions, Mars exploration missions, and new-generation launch vehicles, high-density launches have become the norm. Engines are in increasing demand. [0003] In the development process of liquid rocket engines and aeroengines, actual machine testing is one of the main means to verify their performance. During the test, the on-site collection of various dynamic parameters of the test model can effectively grasp its operating status and performance, and provide reliable data support for performance verification, failure analysis and improved design.
