On-line quality and mass center measurement platform for assembly butt-joint scene

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...
