Six-degree-of-freedom motion platform

Abstract

The invention discloses a six-degree-of-freedom motion platform. The six-degree-of-freedom motion platform comprises electric push rods, a top platform, a connecting seat, a bottom supporting table and a lifting hook mechanism. The six electric push rods are installed on the surface of the top of the bottom supporting table through hinge seats, and the tops of the electric push rods are fixedly connected with the bottom of the top platform through hinge seats. The connecting seat is fixed to the middle position of the top surface of the bottom supporting table, a through hole is formed in thecenter of the top platform, and the lifting hook mechanism penetrates through the through hole to be fixedly connected with the connecting seat. The lifting hook mechanism is composed of a connectingrod and a lifting hook, the lifting hook is welded and fixed to the top of the connecting rod, and threads are formed in the surface of the lower part of the connecting rod. The connecting seat is composed of a connecting seat body and a connecting sleeve. According to the six-degree-of-freedom motion platform, auxiliary hoisting is carried out through the lifting hook mechanism and the connectingseat, the weight of the device is borne by the bottom supporting table, the electric push rods do not bear tension any more, and therefore the situation that the electric push rods are pulled to be damaged is avoided.

Description

technical field [0001] The invention belongs to the technical field of motion platforms, and in particular relates to a six-degree-of-freedom motion platform. Background technique [0002] The six-degree-of-freedom motion platform is composed of six actuators, six upper and lower universal hinges and two upper and lower platforms. The lower platform is fixed on the foundation. With the help of the telescopic movement of the six actuators, the upper The platform moves in six degrees of freedom (X, Y, Z, α, β, γ) in space, so that various spatial motion postures can be simulated. It can be widely used in various training simulators such as flight simulators, ship simulators, naval helicopter take-off and landing simulation platforms, tank simulators, car driving simulators, train driving simulators, earthquake simulators, dynamic movies, entertainment equipment, etc. , even can be used in the docking of space spacecraft and the refueling docking of air tankers. The standard ...

AI Technical Summary

Problems solved by technology

[0003] At present, the large-scale six-degree-of-freedom motion platform is difficult to transport. If the direct hoisting method is adopted, the weight of the six-degree-of-freedom motion platform will be borne by the electric push rod, which makes the electric push rod easy to be pulled.
