A multi-degree-of-freedom quick connection device

Abstract

The invention provides a multi-degree-of-freedom fast connection device which comprises a three-rotation mechanism and a three-movement mechanism. The three-rotation mechanism and the three-movement mechanism are connected through a connecting shaft and a connecting sleeve; the connecting sleeve is provided with a first hand wheel used for adjusting the height of the connecting sleeve; the connecting shaft is provided with a second hand wheel used for adjusting the rotation direction of the connecting shaft; the three-movement mechanism comprises a fixed base, a fixed plate and a support plate; the support plate is arranged between the fixed base and the fixed plate; the upper surface of the fixed base is of a groove structure; the upper end surfaces of two sides of the groove structure are connected with the fixed plate through fastening pieces; the three-rotation mechanism comprises a hook joint and a connecting cylinder; the upper end in the connecting cylinder is connected with theconnecting shaft; the lower end of the connecting cylinder is connected with a threaded shaft on one side of the hook joint; and the other side of the hook joint is of a pin shaft structure. The multi-degree-of-freedom fast connection device provided by the invention is reliable in connection, small and compact in volume, high in rigidity, simple and convenient to operate, short in time requiredfor connecting, and capable of accomplishing connecting operation independent of a tool.

Description

technical field

[0001] The invention relates to the field of mechanical technology, in particular to a multi-degree-of-freedom quick connection device. Background technique

[0002] At present, in the process of moving goods at the freight terminal or warehouse, the crane generally uses the grab hook to complete the handling of the goods. It is simple and fast, but there are also potential safety hazards, and it can only complete some positions that do not require high position accuracy. If a certain degree of precision is required for the operation, the work efficiency will be greatly reduced, and the operation and control will become complicated.

[0003] Especially for the precise assembly and disassembly of some large parts, such as the assembly between the satellite cabin and the satellite body, the assembly during the maintenance of the aero-engine, the assembly between the rocket launchers, etc., the steel wire rope and the grapple are generally used to facilitate the...
