Problems solved by technology

Among them, the multi-point support method and the unbalanced moment method are more suitable for the measurement of the center of mass of large cylindrical sections. However, due to the need for strict leveling during the measurement of the center of mass, the measurement of the radial center of mass needs to accurately change the measurement attitude and other difficulties, and the movable center of mass has not yet been realized. measuring platform

Embodiment Construction

[0036] An assembly and docking on-site online mass centroid measurement platform includes a chassis component 1, a mass centroid measurement component 2, and an attitude adjustment component 3. The attitude adjustment component 3 is installed on the mass centroid measurement component 2 , and the mass centroid measurement component 2 is installed on the chassis 1 . It can realize attitude adjustment docking and mass centroid measurement functions.

[0037] The chassis assembly 1 can drive the platform to move back and forth, or provide a horizontal reference for the measurement of the center of mass.

[0038] Chassis assembly 1 includes motor A7, reducer 6, steel wheel A5, motor B8, reducer 9, steel wheel B10, lifting and separating mechanism A11, steel wheel C12, lifting and separating mechanism B13, lifting and separating mechanism C14, lifting and separating mechanism D15, Steel wheel D16, level sensor 17, laser tracker ball seat 18 are all installed on the chassis support...

Abstract

The invention discloses an on-line quality and mass center measurement platform for an assembly butt-joint scene. The on-line quality and mass center measurement platform comprises a chassis assembly,a quality and mass center measurement assembly and a posture adjusting assembly; the posture adjusting assembly is installed on the quality and mass center measurement assembly, and the quality and mass center measurement assembly is installed on a chassis. Through the on-line quality and mass center measurement platform, portions can be automatically transferred in a factory, and meanwhile automatic posture adjustment can be realized with high precision for horizontal movement, lifting, pitching, yawing and rolling of the portions, and at any station, the quality, an axial mass center and aradial mass center are measured without assembling and disassembling supporting portions of the portions.

Description

technical field [0001] The invention belongs to the field of measurement platforms, and in particular relates to an on-site mass centroid measurement platform for assembly and docking. Background technique [0002] In the field of national defense, the position of the center of mass is related to the performance of missile trajectory and control, rocket attitude control, etc. When the center of mass deviates, additional torque will be generated to change its trajectory. The radial center of mass deviation will cause yaw moment, and the axial center of mass deviation will cause pitching moment, so the center of mass needs to be precisely measured during the production assembly process. Due to the complex structure of missiles and rockets and a large number of internal installation parts, it is difficult to accurately determine the position of their center of mass through theoretical calculations. The center of mass measurement needs to be carried out during the assembly of t...
