Problems solved by technology

The operation process of this process is complicated and the efficiency is low. Each measurement takes about 3 hours. If the coaxiality does not meet the requirements, it is necessary to re-measure after adjusting the thrust measurement component until the coaxiality meets the requirements.

Abstract

The invention discloses a ground test measuring device which comprises a thrust wall provided with an adjusting mechanism for up-down and left-right adjustment. The adjusting mechanism is connected with a centering plate. The center of the centering plate is provided with a centering hole. The device is further provided with an engine support mechanism. A thrust transition frame and a centering detection mechanism are arranged between the support mechanism and the centering plate. One end of the thrust transition frame and an engine end portion are positioned. The other end of the thrust transition frame is connected with the centering detection mechanism. The centering detection device comprises a base, a shaft sleeve and a mandrel, wherein the base is fixedly connected with the shaft sleeve, and the mandrel is movably sleeved by the shaft sleeve and is connected to the centering hole at an end close to the centering plate. The device can enable the axis of the engine and a thrust measuring component to be coaxial, realizes rapid and efficient detection, is convenient to operate, can complete each test within 10 minutes, saves at least 50% labor, greatly improves precision, and achieves the coaxial precision of 0.5mm.

Description

technical field [0001] The invention belongs to the technical field of engine ground test devices, and in particular relates to a ground test measuring device. Background technique [0002] During the development and production of solid rocket motors, it is necessary to assess the structural integrity of the various components of the engine through ground tests, and measure parameters such as pressure, thrust, and temperature during the working process of the engine. Among them, the thrust measurement of the engine is very important, and it is mainly used to judge the performance of the engine. energy properties. [0003] When the engine is tested on the ground, the engine thrust is evaluated by testing the axial thrust. In order to ensure the accuracy of the engine axial thrust test, after the engine is installed and fixed on the test frame, it is necessary to ensure that the axis of the engine is consistent with the axis of the thrust measurement component (mainly the thru...
