A three-degree-of-freedom satellite high-precision component assembly and adjustment mechanism

Abstract

The invention relates to a three-degree-of-freedom high-precision satellite component assembly and adjustment mechanism. A three-degree-of-freedom displacement adjustment device is mounted on the mounting reference plane to be provided with a satellite component through a base, and the three adjustment directions of the three-degree-of-freedom displacement adjustment device are parallel to the direction of an assembly coordinate system; a mounting-clamping mechanism comprises a circular base, a connecting rod I, a connecting rod II, a transfer rod and a mounting-clamping clamp plate; the circular base is mounted on the three-degree-of-freedom displacement adjustment device, the circular base and one end of the connecting rod I form a revolute pair, the other end of the connecting rod I and one end of the connecting rod II form a revolute pair, the other end of the connecting rod II is fixedly connected with the transfer rod, and one end of the mounting-clamping clamp plate is a clamping end used for clamping the satellite component to be mounted; two circular arc adjustment grooves are formed in the other end of the mounting-clamping clamp plate, the transfer rod is inserted in the connecting rod II and fixed to form a whole with the connecting rod II, and two cylindrical rods are designed at the other end of the transfer rod, are inserted in the two circular arc adjustment grooves of the mounting-clamping clamp plate respectively and can rotate relative to the adjustment grooves.

Description

technical field [0001] The invention belongs to an assembly and adjustment mechanism for three-degree-of-freedom translation adjustment of high-precision components, and is applied to the field of assembly and adjustment of high-precision components on spacecraft. Background technique [0002] At present, most structural components on domestic and foreign spacecraft lack special adjustment mechanisms in the final fine adjustment process. Usually, the method of manually tapping the product to make a small amount of displacement is used. The advantage of this method is that the adjustment direction is relatively free and flexible. It can adjust the posture in multiple directions according to the needs of the site. The disadvantage is that the displacement and direction of each adjustment are not easy to control, and it is impossible to achieve a stable and reliable translation adjustment in the three-degree-of-freedom direction. Adjust the posture when the product is not heavy...

Problems solved by technology

The advantage of these high-precision component assembly and adjustment mechanisms is that the assembly and adjustment posture control is precise, and the pose transformation under 6 degrees of freedom can be realized, but the disadvantage is that the assembly and adjustment mechanism is very complicated and occupies a large area. The assembly and adjustment of small and light-weight parts is too cumbersome, it is difficult to realize the product assembly, and it is easy to cause collision interference between the assembly mechanism and the product
