Six-degree-of-freedom (DOF) reset device for balance calibration system

Abstract

The invention relates to a six-degree-of-freedom (DOF) reset device for a balance calibration system, wherein an axial linear motion mechanism is positioned at the bottom end, a lateral linear motion mechanism is positioned on the upper surface of the axial linear motion mechanism, and an upper guide rail on the lower surface of the lateral linear motion mechanism is fixedly connected with a lower support seat of the axial linear motion mechanism; a square chest of a normal linear motion mechanism is fixedly connected with a slide block on the guide rail of the lateral linear motion mechanism; a headstock of a pitch angle motion mechanism is connected with a lifting frame of the normal linear motion mechanism through a short shaft; a soleplate of a roll angle motion mechanism is fixedly connected with a spindle seat, the spindle seat is connected with a square chest of the pitch angle motion mechanism through a bearing and a mandrel; and a worm wheel of a side slip angle motion mechanism is connected with the spindle seat through a worm wheel shaft. The six-DOF reset device for the balance calibration system has large system rigidity, rapid adjustment response and high reset precision, can accurately install, adjust and position a calibrated balance, can adjust with a single degree of freedom and is beneficial to the initial positioning of a loading head.

Description

technical field [0001] The present invention relates to a calibration test device, in particular to an aviation system that accurately applies a calibration load to each load component of a calibrated balance according to an accurately known coordinate axis system, so as to obtain the signal output of each component of the balance and the change of the load Relational balance calibration system with six degrees of freedom reset device. Background technique [0002] Calibration of the body axis of the balance requires that the load on the balance during the static calibration process is always consistent with the coordinates of the body axis system of the loading head installed on the model side of the balance. When the balance and support are deformed under load, the loading head can be restored to the position and state before loading through the automatic measurement, control and adjustment system, or the loading axis can follow the change of the coordinate axis of the loa...
