Five-dimensional direction adjustment system with gravity compensating mechanism

Abstract

The invention discloses a five-dimensional direction adjustment system with a gravity compensating mechanism. A back plate is arranged in perpendicular to a direction adjustment table; a base plate (a) moves vertically and reciprocally relative to the back plate; a locking mechanism and a first height adjustment unit are mounted on the back plate; an extending connecting plate is mounted on a sidesurface of the base plate (a); the top of the first height adjustment unit is supported to the lower surface of the extending connecting plate; the gravity compensating mechanism comprises a pre-stretched or pre-compressed spring; two ends of the spring are respectively connected to the back plate and the base plate (a); the elastic force of the spring is always upwards; a base plate (b) is fixedto the base plate (a) through second height adjustment units; the second height adjustment units are vertically arranged at three corners of the base plate (b) to adjust the height, inclination angleand pitch angle of the base plate (b); and a base plate (c) performs X-directional and / or Y-directional movement by adjusting an X-directional adjustment unit and a Y-directional adjustment unit. Thefive-dimensional direction adjustment system with the gravity compensating mechanism provided by the invention realizes five-directional adjustment independently without interfering with one another.

Description

technical field [0001] The invention belongs to the technical field of mechanical precision control, and in particular relates to a five-dimensional direction adjustment system with a gravity compensation mechanism. Background technique [0002] At present, most of the existing precision equipment position adjustment mechanisms will adopt one-dimensional, two-dimensional, three-dimensional or four-dimensional and their combination methods, which need to be matched with various types of adjustment equipment to realize it. Only two-dimensional plane adjustment can continue to the next step of three-dimensional and four-dimensional adjustment. The working process is complicated, and the instrument operation steps are cumbersome. In addition, during the adjustment process, it is easily affected by gravity, and the thrust used for vertical elevation is too large, which is often difficult. Adjust or achieve precise adjustment, and it is easy to produce height position deviation wh...

[0002] At present, most of the existing precision equipment position adjustment mechanisms will adopt one-dimensional, two-dimensional, three-dimensional or four-dimensional and their combination methods, which need to be matched with various types of adjustment equipment to realize it. Only two-dimensional plane adjustment can continue to the next step of three-dimensional and four-dimensional adjustment. The working process is complicated, and the instrument operation steps are cumbersome. In addition, during the adjustment process, it is easily affected by gravity, and the thrust used for vertical elevation is too large, which is often difficult. Adjust or achieve precise adjustment, and it is easy to produce height position deviation when locking, and the stability and repeatability are poor
