Abstract
The utility model discloses a six freedom degrees motion platform comprising an upper platform (1), a lower platform (2) and six electric pushing rods (3). The electric pushing rods (3) are distributed between the upper platform (1) and the lower platform (2). Two ends of each electric pushing rod (3) are respectively hinged with the upper platform (1) and the lower platform (2) through a hinged supporting base (4) in a one-to-one correspondence mode. A closeness cavity (36) is arranged in a cylinder barrel (33) of each electric pushing rod (3), and communicated with an air suction power source. Pressure gas/hydraulic pressure enter into the closeness cavity (36) and act on a lead screw pair (321) of each electric pushing rod (3). The direction of the acting force imposed on the screw lead pair (321) by the pressure gas/hydraulic pressure is opposite to that of the heavy-load acting force on the upper platform (1). The acting force is used for pneumatically supporting the screw lead pair (321). Due to the fact that gas-electric-integration pushing rods are adopted, supporting capacity of the electric pushing rods is increased, the structure is simple, and manufacture cost is low.
Description
Technical field
The utility model relates to the multi-degree-of-freedom motion platform technical field, particularly a kind of heavily loaded 6-dof motion platform.
Background technology
The 6-dof motion platform of standard is mainly used in heavily loaded lifting, by the change of six-freedom degree, thereby with the equipment on the platform or other article fast and flexible move to suitable position.
The heavily loaded six degree of freedom platform of tradition adopts hydraulic-driven more, needs equipment many, and power consumption is large, and the problems such as noise, precision are also more serious, so the trend to electronic development is arranged in the industry gradually.
Chinese patent literature CN201723926U discloses a kind of electromechanical motion platform with six degree of freedom, comprise the platform upper plate, the platform lower shoe, and the electric cylinder assembly that is connected in six electric cylinder assemblies between platform upper plate and the platform lower shoe, one end of electric cylinder assembly is with after the upper hinge support assembly is connected, be connected to the platform upper plate by the upper hinge support Connection Block, the other end of electric cylinder assembly is connected to the platform lower shoe by the lower hinge support assembly, realize X by the stroke of controlling six electric cylinder assemblies, Y, Z three axle straight-line motions, along X, Y, Z three axles rotate, or the compound motion of straight-line motion and rotation.Its compact conformation, it is little that integral body is occupied the space, motion accurately, it is generally less that yet electric cylinder is exerted oneself, need replacing than the drive motor of high pulling torque if increasing exerts oneself, need simultaneously to increase the leading screw that is complementary with driving torque and the scantling of structure of lead screw pair, then very high by changing the cost that drive motor, leading screw and lead screw pair spend.
Used hinged-support adopts isometrical main shaft in the above-mentioned patent documentation, analysis according to channel angular main shaft stressing conditions, can find out, hinged-support its stressed difference in each position when work is larger, bearing load point at main shaft has larger application force, this also is to cause that main shaft produces diastrophic Main Function power, then stressed less near the main shaft two ends, when increasing bearing load, if adopt the mode of the whole main shaft diameter of isometrical increase, can strengthen to a certain extent the support strength of main shaft; Simultaneously, this isometrical increase main shaft frame mode will significantly increase the weight of whole main shaft and the area of contact between main shaft end and the plain bearing virtually.Owing to adopting bearing fit between the bearing seat at main shaft and its two ends, the object of adding on the motion platform can produce more than ten ton supported weight, make it rotate to change support angle if handle main shaft, the larger application force that on the main shaft end, produces need to be overcome, larger power certainly will be consumed like this.
Simultaneously, above-mentioned shaft stool heavy loaded bearing adopts traditional lubricant film, is easy to during long operational time lose efficacy, and can cause the wearing and tearing between axle and the plain bearing, and then affect the supporting capacity of axle head, and cause load-carrying capacity to reduce, affect the service life of axle and plain bearing.
