The invention relates to the field of gantry type motion platforms, in particular to a large-stroke gantry type motion platform which comprises two longitudinal supports arranged at the upper end of the platform and parallel to each other and a transverse support with the two ends connected with the longitudinal supports through air flotation assemblies, and a working mechanism is connected to the center of the transverse support. The transverse supports are driven by driving devices arranged on the longitudinal supports to move in the length direction of the longitudinal supports. The air floating assembly comprises a floating plate connected with the lower end face of the transverse support, and the lower end of the floating plate is at least connected with two first air feet. A steel plate is arranged on the longitudinal support, a magnet is arranged on the transverse support, and the magnet and the steel plate attract each other. The gravity center of the load and the output gravity center of the driving device are arranged on the same horizontal plane, equivalently, the torque between the driving device and the load is reduced, and the torque of the load is reduced; meanwhile, the air feet at the front end and the rear end of the floating plate in the moving direction can be kept to adopt a small distance.
本发明涉及龙门式运动平台领域,具体为一种大行程龙门运动平台,包括设置在平台上端且相互平行的两个纵向支架,两端分别通过气浮组件与纵向支架连接的横向支架,工作机构连接在横向支架的居中处;所述横向支架分别通过设置在纵向支架上的驱动装置驱动沿纵向支架的长度方向运动;所述气浮组件包括与横向支架下端面连接的浮板,所述浮板的下端至少连接两个第一气足;所述纵向支架上设置有钢板,所述横向支架上设置有磁铁,所述磁铁与钢板相吸。通过将负载的重心和驱动装置的出力重心设置在接近于同一水平面上,相当于减小驱动装置与负载之间的力矩,降低负载的扭矩;同时,可以保持浮板上运动方向前后端气足的采用较小的间距。
