A Five-Dimensional Orientation Adjustment System with Gravity Compensation Mechanism

Abstract

The invention discloses a five-dimensional direction adjustment system with a gravity compensation mechanism. The back plate is vertically arranged with the direction adjustment platform, the base plate a reciprocates vertically relative to the back plate, and a locking mechanism and a first height adjustment unit are installed on the back plate. , an extension connecting plate is installed on the side of the base a, the top of the first height adjustment unit is supported under the extending connecting plate, the gravity compensation mechanism includes a pre-stretched or pre-compressed spring, and the two ends of the spring are respectively connected to the back plate and the base a, and the elastic force of the spring is always Upward, the substrate b is fixed on the substrate a through the second height adjustment unit, and the second height adjustment unit is vertically arranged at the three corners of the substrate b to adjust the height, inclination angle and pitch angle of the substrate b. The unit and the Y-direction adjustment unit move the substrate c in the X-direction and / or the Y-direction. The five-dimensional direction adjustment system with a gravity compensation mechanism provided by the present invention realizes five-dimensional adjustment, which can be performed independently without interfering with each other.

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...

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
