Abstract

The invention relates to a method and a system for controlling the posture of an extra-large gear. The method comprises the following steps: corresponding adjustment amount of four driving motors for driving a posture adjusting platform is acquired through an upper computer; the upper computer sends a first control command to a motion control unit according to the corresponding adjustment amount of the four driving motors; the motion control unit sends corresponding impulse control signals to four stepping motors respectively according to the first control command; and the four stepping motors drive four mechanical transmission structures corresponding to the four stepping motors respectively according to corresponding impulse control signals, so as to control the posture adjusting platform to adjust the position of a three dimensional measuring platform. The embodiment of the invention has the advantage that low-angle and quick measurement of an in-suit measuring system of the whole extra-large gear can be realized according to the position of the extra-large gear.

Description

technical field [0001] The invention relates to the technical field of three-dimensional measurement, in particular to a method and system for attitude control of an oversized gear. Background technique [0002] In various technical fields such as modern manufacturing, high-precision measurement, military and civilian production and manufacturing, it is necessary to adjust the attitude of measuring equipment or measuring instruments (such as three-dimensional measuring platforms), so as to adjust the measuring equipment or measuring instruments to the specified angle and position , to improve the measurement accuracy of the measured object, so as to meet the specific test indicators. [0003] The posture adjustment methods in the prior art are based on three-point or multi-point support adjustment, multi-link adjustment, multi-axis parallel adjustment, chain sprocket adjustment and other methods. For extra-large gears, due to their large weight and volume, the existing tech...
