Abstract

The invention discloses a positioning device. The positioning device comprises a supporting device used for supporting an instrument grillwork assembly, the supported instrument grillwork assembly comprises an instrument grillwork and an assembly extending downwards from the bottom of the instrument grillwork, and the supporting device is arranged at the bottom of the instrument grillwork and used for supporting the instrument grillwork. The supporting device comprises a supporting body and multiple lifting devices. One end of each lifting device is installed on the supporting body, and the other end of each lifting device is connected to the bottom of the instrument grillwork in a lifting manner so that the levelness of the instrument grillwork can be adjusted. By means of the lifting devices, accurate positioning is provided for installation of the instrument grillwork assembly, the equipment use cost of a machine tool and a cutter is reduced, the machining efficiency is improved, and the manufacturing period is remarkably shortened.

Description

technical field [0001] The present application relates to the technical field of machining, in particular to a positioning device for an instrument grid assembly. Background technique [0002] The measuring instrument grid support assembly (instrument grid assembly, hereinafter referred to as IGA assembly) includes an instrument grid and irregularly distributed components extending along the surface of the instrument grid. The circumferential diameter of the instrument grid is usually between 3000-4000mm, and its thickness is about 100mm. Wherein, after the welding and rectification of components are completed on the bottom surface of the instrument grid, the instrument grid still needs to be machined. However, in the process of machining, since the connecting side of the instrument grid and the components directly contacts the processing platform, it is difficult to meet the flatness requirements of the instrument grid components, and it is difficult to meet the verticalit...
