Abstract

A support device that combines ball sockets, column sockets, and planes in centroid measurement involves a support structure to solve the problem that the sensor is difficult to automatically adjust to the center of the bearing point in the existing ball-ball-socket support method for centroid measurement. The centering position accuracy is poor and the ball plane support method has the problem of large guiding friction, which includes a ball socket support structure, a ball plane support structure and a measuring pedestal; the support device also includes a column socket support structure; the column socket support structure Including column nest plate, steel ball, ball seat, load-bearing sensor, load-bearing sensor tray and base, load-bearing sensor is installed on the load-bearing sensor tray, the load-bearing sensor tray is rotated and installed on the base, the base is installed on the measuring platform, and the ball seat is detachable and installed On the load-bearing sensor, a steel ball is placed in the middle of the upper surface of the ball seat, and a horizontally arranged column socket plate is placed on the upper part of the steel ball. The invention is used for the measurement of the centroid of large-scale aircraft.

Description

technical field [0001] The invention relates to a support structure, in particular to a support structure of large-scale aircraft centroid measurement equipment. Background technique [0002] The support method of large-scale aircraft centroid measurement equipment and the problem of lateral force have always existed, which affect the measurement accuracy. From the basic principle of the multi-point method, it can be known that the output value of the sensor and the measurement value of the position of the force point of the sensor directly affect the measurement result of the mass center of mass, so how to ensure the accuracy of the output value of the sensor and the measurement value of the position of the force point of the sensor center has become an important issue for improvement. The key factor for the measurement accuracy of the centroid of mass measuring platform. The supporting structure of the sensor is a key factor affecting the output characteristics of the sen...
