Abstract

The invention discloses a connecting rod type three-degree-of-freedom position adjusting device. The device comprises a fixed frame, a movable frame, connecting rods, a base, a sliding block, a clamp,a hydraulic oil cylinder and cross-shaped sliding blocks, wherein the fixed frame and the movable frame are arranged at the left end and the right end of a butt joint device in parallel, each cornerof the fixed frame and each corner of the movable frame are fixedly provided with the cross-shaped sliding blocks, every two adjacent cross-shaped sliding blocks are connected through the connecting rods, one end of the hydraulic oil cylinder is connected with the fixed frame through a spherical hinge mode, the other end of the hydraulic oil cylinder is connected with the connecting rods through the spherical hinge mode, the hydraulic oil cylinder stretches out and draws back so that translational swing of the fixed frame in the Y direction and the translational swing of the movable frame in the Z direction can be realized, and the sliding blocks are driven to move in the X direction at the same time.

Description

technical field

[0001] The invention relates to a link type three-degree-of-freedom position adjustment device, which belongs to the technical field of automatic docking. Background technique

[0002] At present, when the rocket is refueled, the connector on the ground refueling pipeline needs to be docked with the valve on the rocket. For the relatively static situation, the high-altitude connector is mostly manually connected in the final assembly and test plant. Leakage and other situations will affect the personal safety of the site; if in the relative movement or toxic gas environment, or the emergency treatment system, the manual work cannot be completed quickly within the specified time, or in heavy fog, rain, snow and other climates, In the case of manual inconvenient handling, there is no mature technology application at present. Contents of the invention

[0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, pr...

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is further described, and following embodiment is used for illustrating the present invention, but is not used for limiting the scope of the present invention.

[0022] Such as figure 1 As shown, the structure of the present invention consists of a fixed frame 1, a movable frame 2, a connecting rod 3, a base 4, a slider 5, a clamp 6, a hydraulic cylinder 7 (including two hydraulic cylinders A and two hydraulic cylinders B), cross slides Block 8 composition.

[0023] Fixed frame 1, movable frame 2 such as figure 2 , image 3 As shown, it can be a rectangular frame structure. The fixed frame 1 and the movable frame 2 are arranged in parallel at the left and right ends of the docking device. The four corners of the fixed frame 1 and the movable frame 2 are respectively fixed with a combination of cross sliders, figure 1 Shown left and right every two cross slider combinations are connected by a con...
