Component quality characteristic integration test equipment and test method

Abstract

The invention provides equipment used for integrated measurement of quality characteristic of the parts; a torsion pendulum lower disc is fixed on a base; a torsion pendulum upper disc is connected with the torsion pendulum lower disc by a torsion spring component; the torsion pendulum lower disc and the torsion pendulum upper disc are fixedly connected with each other by a bolt; when the bolt isloosened, compressed air is injected in the air inlet hole of the torsion pendulum lower disc so as to form an air cushion between the torsion pendulum lower disc and the torsion pendulum upper disc;the torsion pendulum upper disc is arranged in an air-floating state and carries out torsion pendulum fro and back under the action of a torsion pendulum driving mechanism and the torsion spring component; a rotation inertia measurement instrument measures the rotation inertia of the article to be measured according to the torsion-pendulum period of the torsion pendulum upper disc; a supporting frame is fixed on the external circumference of the torsion pendulum upper disc; a mass center disc is fixed on the supporting frame by a conversion mechanism; the mass center disc is provided with thearticle to be measured; a weighing sensor component is arranged on the surface of the torsion pendulum upper disc; the relative position of the mass center disc and the supporting frame can be changed by the conversion mechanism; when the mass center disc is separated from the supporting frame, the weight of the mass center disc and the article to be measured is borne by the weighing sensor; and the mass and the mass center of the article to be measured is measured by a mass and mass center measurement instrument according to the value of the sensor component.

Description

technical field [0001] The invention relates to a measuring device, in particular to a testing device and a testing method thereof for testing the characteristics of auto parts and complete vehicles, satellites and spaceships and other spacecraft parts and complete machines, and testing the quality characteristics of aviation weapon products . Background technique [0002] Quality characteristics are important parameters in the manufacturing, testing and on-orbit operation of aerospace, aviation and auto parts, and complete machines. It can also reduce the card loading process to improve test efficiency and safety. [0003] Quality characteristics include mass, center of mass and moment of inertia. At present, the quality characteristic testing equipment at home and abroad is divided into four categories in terms of function: (1) quality testing equipment; (2) quality and center of mass testing equipment, such as Hubei Xiaogan Testing Instrument Factory. The quality and ce...

Problems solved by technology

Therefore, during the measurement process, it is necessary to perform multiple assembly and disassembly of the tested part and change the equipment. The test process is complex, the cycle is long, and the efficiency is low. The accuracy consistency during the test process is easily affected by multiple assembly and disassembly.
