Up to the measurement row for core, and using the docking system being made of carrying platform, lifting column, sliding block and turntable etc., construct one
Antenna automatic butt system, the Zhou Hong of Chengdu Zhong electricity Jin Jiang Rivers company et al. is covered, one kind is devised and employs parallelogram mechanism
The six degree of freedom buttjunction platform being formed by combining is successfully realized the automatic butt of certain model metre wave radar antenna.Background satellite
Bear great waves of environmental project research institute et al. have developed a set of satellite using indoor GPS technology and six degree of freedom 6-SPS parallel institutions
Automatic butt system.Jin Qingmian of industry Shen Fei companies of Air China et al., using the tooling controlled by PLC and with laser tracker and
Laser collimator is core measuring system, and the automatic butt of airframe each section is tested.
The work in-process heart, positioning and orientation machinery, measuring machine, the fields such as make-up machinery obtain parallel institution at present
Using.In recent years, parallel institution is used to support the research in terms of posture adjustment and also achieves certain achievement, such as Tongji University is directed to
3RPS parallel institutions have carried out correlative study for motor support rack;It 2001, contains English etc. and Stewart parallel institutions is used
In vehicle radar antenna automatic horizontal control system, so as to provide one for application of the parallel institution in automatic leveling support system
Feasible reference frame;The large-scale astronomical telescope that Bochum, Germany Rule university built in 1999 in campus, it is used
The parallel institution of Stewart platforms is as posture adjustment supporting mechanism, etc..In addition, parallel institution can be not using redundant drive with regard to energy
Enough realize the posture adjustment campaign of six degree of freedom, control is simple.In view of above research, it is seen that parallel institution has for large component
The potential of posture adjustment assembly system.
