Tool and method for detecting mass center and mass deviation of special-shaped brittle ceramic structural component

Abstract

The invention discloses a tool and method for detecting the mass center and mass deviation of a special-shaped brittle ceramic structural part. The tool comprises a detection platform, a rotating wheel set is arranged on the detection platform, a tool body is arranged on the rotating wheel set, and a datum plate which is vertically arranged and has the same rotating axis with the tool body is arranged in the tool body; the outer side face of the datum plate is an outer datum plane, the inner side face of the datum plate is movably connected with a connecting ring which is horizontally arranged and has the same rotating axis with the datum plate, the periphery of the connecting ring is used for being sleeved with the special-shaped brittle ceramic structural part, and the end face of a port of the special-shaped brittle ceramic structural part is flush with the inner side face of the datum plate. A plurality of balancing weights are arranged on the periphery of the outer side of the tool body. The device further comprises an automatic reading system capable of automatically reading the mass, the mass center, the eccentric distance and the eccentric angle. According to the detection method, the measurement precision of the mass center and the mass deviation of the special-shaped brittle ceramic structural member is improved, the measurement stability is good, and the measurement requirements of special-shaped brittle structural aircraft products can be met.

Description

technical field [0001] The invention relates to the technical field of detection of ceramic products with special-shaped brittle structures for aircraft, in particular to a center of mass and mass deviation detection tool and detection method of special-shaped brittle ceramic structures. Background technique [0002] The center of mass and mass deflection are the inherent characteristics of the aircraft's structural parts, and they are the parameters that must be controlled to ensure that the aircraft can maintain its flight attitude. The position of the center of mass affects the stability and speed of the aircraft, and the mass deviation determines the flight trajectory and flight accuracy. Therefore, measuring them is of great significance. [0003] When performing centroid and mass deviation measurement, it is necessary to obtain accurate reference point data, determine row position parameters, and convert to obtain accurate centroid data. The measurement methods of the...

Problems solved by technology

On the one hand, these special-shaped brittle ceramic structural parts have no holes, slots, etc. available for connection, and on the other hand, the irregular shape of the structural parts is difficult to assemble, which makes it more difficult to detect the center of mass and mass deviation.

[0005] In the prior art, there is no detection tool for detecting the centroid and mass deviation of special-shaped brittle ceramic structural parts. Therefore, a detection tool and detection method capable of detecting the centroid and mass deviation of special-shaped brittle ceramic structural parts are developed to improve detection accuracy and measurement stability. sex imminent
