Embodiment 1

[0020] Embodiment one: if Figure 1 to Figure 6 The light-weight six-degree-of-freedom parallel swing platform shown includes an upper platform 1 and a lower platform 2, and three rigid branch chains I and three lightweight branch chains II are movably connected between the upper platform 1 and the lower platform 2 , the rigid branch chain I and the lightweight branch chain II are staggered and evenly distributed between the upper platform 1 and the lower platform 2, and the specifications and parameters of the components used in the three rigid branch chains I and the three lightweight branch chains II are the same of.

[0021] The rigid branch chain I has a telescopically adjustable electric push rod, the electric push rod includes a piston rod 5, a cylinder body 6 and a stepping motor 7, and the rigid branch chain I and the upper platform 1 pass through the first ball joint 3 connection, the rigid branch chain I and the lower platform 2 are connected through the second bal...

Embodiment 2

[0027] Embodiment two: if Figure 7 As shown, a lightweight six-degree-of-freedom parallel swing platform also includes the upper platform 1, the lower platform 2 and the lightweight branch chain II with the same structure. The difference between this embodiment and the first embodiment is that the rigid branch chain I is cancelled. , change the three rigid branch chains I in Embodiment 1 into three lightweight branch chains II, and correspondingly, the reel motor 24 on the lower platform 2 is increased from the original three to six. Compared with Embodiment 1, the embodiment The swing table in No. 2 requires higher quality and precision of the compression spring 12. Under the same conditions, the oscillating table in the first embodiment has higher precision, but the second embodiment is suitable for occasions that do not require high conditions of use.

Abstract

The invention relates to a lightweight six-degree-of-freedom parallel swing table which has the advantages of light weight, small inertia force, large degree of freedom, strong adaptive capacity and the like, and can remarkably reduce the driving energy consumption when a mechanism moves. Due to the application of the lightweight branched chain flexible component, the load is in flexible contact with a movable base, rigid impact is reduced, and the high-frequency vibration isolation performance can be improved. The device comprises an upper platform and a lower platform, wherein three rigid branched chains and three lightweight branched chains are movably connected between the upper platform and the lower platform, the rigid branched chains and the lightweight branched chains are uniformlydistributed between the upper platform and the lower platform in a staggered manner, a traction device for controlling and adjusting the positions of the light-weight branched chains is arranged on the lower platform, and the rigid branched chains are provided with electric push rods capable of being telescopically adjusted.

Description

technical field [0001] The invention relates to a lightweight six-degree-of-freedom parallel swing table applied to precision machining, motion simulators, and weapon aiming and tracking. Background technique [0002] In practical application occasions, the swing table can be used as a test bench or as an actual working equipment to develop. For example, a flight simulator is a kind of swing table, which is used to simulate various spatial movements of pilots during actual driving to achieve training purposes; in modern battlefields, rocket launchers and other combat equipment, the role of the swing table is to stabilize the work surface , to meet the accuracy requirements of the attack. The swing test bench can simulate various space motion attitudes, and has very important applications in the fields of flight simulators, ship motion simulators, tank simulators and earthquake simulators. At present, the existing test benches cannot fully meet the actual needs in terms of ...
