A serial six-degree-of-freedom precision adjustment device

Abstract

The invention discloses a tandem type six-degree-of-freedom accurate adjustment device which comprises an X-direction moving layer moving along the X-axis, a Y-direction moving layer moving along the Y-axis, a Z-direction moving layer moving along the Z-axis, an X-direction rotating layer eccentrically rotating around the X-axis, a Y-direction rotating layer eccentrically rotating around the Y-axis and a Z-direction rotating layer eccentrically rotating around the Z-axis. The tandem type six-degree-of-freedom accurate adjustment device adopts a tandem type combination mode for the first time, independent movement and adjustment can be achieved in the direction of each axis when the position of a product is adjusted, and six-degree-of-freedom free posture adjustment is achieved. Compared with a parallel type structure, the tandem type structure is simpler. Meanwhile, the tandem type six-degree-of-freedom accurate adjustment device can be used for manual adjustment.

Description

technical field [0001] The invention relates to a serial six-degree-of-freedom precision adjustment device, which belongs to the field of attitude control of space mechanisms. Background technique [0002] In recent years, general assembly technology has been lagging behind processing technology, and mechanical assembly technology has gradually become a weak link in realizing production modernization. Assembly problems will lead to product performance degradation, and even lead to accidents, so enough attention should be paid to the assembly of mechanical products. At present, assembly is mainly divided into two types: manual assembly and automatic assembly. Manual assembly is the main assembly method at present, and its assembly process is mainly completed by manual operation, which has the disadvantages of low precision, poor stability, high labor intensity, and high cost. Mechanical automated assembly has the advantages of high efficiency, high precision, and good stabi...

AI Technical Summary

Problems solved by technology

This is the most primitive manual assembly operation mode for production. Under the current situation of rapid development of digitalization and automation, its docking assembly technology has been difficult to adapt to the development of the new situation.

As the space deployment mechanism becomes more sophisticated and complex, higher requirements are put forward for assembly accuracy. Traditional assembly relies on the practical experience and technology of operators, and the assembly quality is unstable.

[0004] To realize automatic assembly, it is necessary to adjust the six degrees of freedom of the workpiece, but currently there are few mechanisms that can achieve six degrees of freedom position adjustment, and because of their own characteristics, it is generally difficult to apply to precision assembly
