Rapid plane movement platform

Abstract

The invention relates to a rapid plane movement platform. The rapid plane movement platform is characterized in that: a lower-layer platform comprises a first lower substrate, a second lower substrate, two lower guide rails, a lower driving rolling gear, a first lower driven rolling gear, a second lower driven rolling gear and a third lower driven rolling gear; an upper-layer platform comprises afirst upper substrate, a second upper substrate, two upper guide rails, an upper driving rolling gear and an upper driven rolling gear; the upper-layer platform is driven by the interaction between the driving rolling gear and the driven rolling gear in the lower-layer platform by virtue of flexible threaded driving lines; and a carrying platform is driven by the interaction between the driving rolling gear and the driven rolling gear in the upper-layer platform by virtue of flexible threaded driving lines, thus orthogonal two-dimensional movement direction of the carrying platform is achieved. The rapid plane movement platform has the advantages of reasonable design of mechanical structure and driving structure, light structure, high driving efficiency, rapid action response, easiness inprocessing and low manufacture cost.

Description

technical field

[0001] The invention belongs to the technical field of motion adjustment platforms, and in particular relates to a fast planar motion platform. Background technique

[0002] Controllable platforms capable of free motion in a plane have a wide variety of applications. The planar inverted pendulum platform imitating the vertical launch control base of the missile can achieve the purpose of erecting and balancing the inverted pendulum by making free and controllable movements in the plane. The stage of the numerical control microscope can find the proper position of the sample to be inspected by making free and controllable movement in the plane. The crane in the factory building can put the hoisted items in a proper position by making controllable free movement in the plane. An earthquake simulator that imitates the most destructive plane wave in an earthquake requires a rapid and controllable movement of the loading platform in the plane, so as to achieve th...
