Problems solved by technology

When using a lead screw to control, in order to realize the movement of multiple degrees of freedom, it is necessary to have more layers of lead screws, and the lead screws are stacked. The bottom height of the platform made by this technology is too high, which is not conducive to the instrument, Loading of equipment; if the platform needs to be lifted and / or translated, it must be realized through the operation of the screw. This kind of platform is only suitable for small and medium-sized loads, and the transmission ratio of this kind of platform is small, the power is low, and the operation is complicated. It also needs manual assistance, which is not convenient for use in engineering; it is also impossible to realize the tilt and rollover of the platform, which is also a big problem for the disassembly and assembly of the platform after the loading and unloading project is completed.

Embodiment 1

[0029] Such as Figure 1~4 As shown, a platform with six degrees of freedom of movement, the platform 1 is a frame 2 platform, a panel 3 is arranged on the upper surface of the frame 2, and six drive components. Three of the six drive components are lift drive components 4, the upper end of the lift drive component 4 is hinged to the platform 1, the lower end of the lift drive component 4 is hinged to the frame 5, The lifting driving part 4 is arranged in a triangle under the platform 1, and universal joint hinges are respectively arranged at both ends of the lifting driving part 4; the other three of the six driving parts are Translation drive part 6, one end of the translation drive part 6 is parallel or obliquely hinged with the platform 1 at the lower end of the panel 3, the other end of the translation drive part 6 is hinged with the frame 5, and the translation drive part 6 is hinged at the lower end of the panel 3. Both ends of the component 6 are provided with joint ...

Embodiment 2

[0031] Such as figure 1 , 2 , 6, on the basis of embodiment 1, a preferred embodiment of the present invention includes that the platform 1 can be a rectangular platform 1, and the rectangular platform 1 can be divided into upper and lower layers, and the frame 2 consists of Several beams and longitudinal beams are spliced ​​together, the panel 3 is laid on the beams and the longitudinal beams, a frame 7 is arranged around the platform 1, and a foot 8 is arranged below the frame 7 , the platform 1 can be controlled to move within the frame 7 .

Embodiment 3

[0033] Such as figure 1 , 3 As shown, on the basis of Embodiment 2, the preferred embodiment of the present invention also includes that the driving component is a piston rod 9 and a cylinder 10 that cooperate with each other, and the piston rod 9 and the cylinder 10 pass through the cylinder 10 The inflow and outflow of gas or liquid in the cylinder can cause relative movement between the piston rod 9 and the cylinder body 10; if the piston rod 9 is used as the driving part, the end of the piston rod 9 can be connected to The platforms 1 are hinged to each other, and the cylinder is hinged to the frame 5 through a hinge; if the cylinder 10 is used as a driving component, the end of the cylinder 10 can be connected to the platform through a hinge 1 are hinged to each other, and the piston rod 9 is hinged to the frame 5 through a hinge.

Abstract

The invention relates to a device for controlling a platform to freely lift, translate and overturn, in particular to a platform with six degrees of freedom of motion. The platform is of a frame structure provided with a panel on the upper surface and is at least articulated with six drive parts; three of the six drive parts are lifting drive parts which are triangularly arranged below the platform, and two ends of the lifting drive parts are respectively provided with universal joint type hinges; the other three of the six drive parts are translation drive parts which are provided with jointbearing type hinges at two ends; the lifting drive parts are used for driving the platform to move along a Z-axis direction, and/or swing around an X-axis, and/or swing round a Y-axis; and the translation drive parts are used for driving the platform to move along the X-axis and/or Y-axis direction and /or swing around a Z-axis. The platform can be controlled to randomly move and/or rotate withinsix degrees of freedom and has the characteristics of small size, flexible running, high bearing capacity, easy assembly and disassembly, and the like.

Description

technical field [0001] The invention relates to a device for controlling free lifting, translation and turning of a platform, in particular to a platform with six degrees of freedom of movement. Background technique [0002] In the prior art, the movement of the positioning platform is mostly driven by a screw. When using a lead screw to control, in order to realize the movement of multiple degrees of freedom, it is necessary to have more layers of lead screws, and the lead screws are stacked. The bottom height of the platform made by this technology is too high, which is not conducive to the instrument, Loading of equipment; if the platform needs to be lifted and / or translated, it must be realized through the operation of the screw. This kind of platform is only suitable for small and medium-sized loads, and the transmission ratio of this kind of platform is small, the power is low, and the operation is complicated. It also needs manual assistance, which is not convenient ...
