Abstract

The invention discloses a six-degree of freedom motion platform, which comprises an upper platform (1), a lower platform (2) and six electric push rods (3), wherein the electric push rods (3) are distributed between the upper platform (1) and the lower platform (2), and two ends of each electric push rod are hinged with the upper platform (1) and the lower platform (2) respectively in a one-to-one correspondence mode by hinged supports (4); a closed cavity (36) which is communicated with an air inlet power source is formed in a cylinder (33) of each electric push rod (3); pressure air / hydraulic pressure in the closed cavity (36) acts on a lead screw pair (321) of each electric push rod (3); and the direction of the acting force, which acts on the lead screw pair (321), of the pressure air / hydraulic pressure is opposite to that of the heavy load acting force of the upper platform (1), and the acting force acting on the lead screw pair is used for supporting the lead screw pair (321) pneumatically. According to the six-degree of freedom motion platform, an integrated pneumoelectric push rod mode is adopted, so that the support capacity of the electric push rods is enhanced, and the six-degree of freedom motion platform is simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of multi-degree-of-freedom motion platforms, in particular to a heavy-duty six-degree-of-freedom motion platform. Background technique [0002] The standard six-degree-of-freedom motion platform is mainly used for heavy-duty lifting. Through the change of six degrees of freedom, the equipment or other items on the platform can be quickly and flexibly moved to a suitable position. [0003] Traditional heavy-duty six-degree-of-freedom platforms mostly use hydraulic drive, which requires a lot of equipment, consumes a lot of power, and has serious problems such as noise and precision. Therefore, there is a trend of gradually developing towards electric in the industry. [0004] Chinese patent document CN201723926U discloses a six-degree-of-freedom electromechanical motion platform, including an upper base plate of the platform, a lower base plate of the platform, and an electric cylinder assembly of six electri...
