A partial top-bending correction mechanism of the inner wall of the movable vacuum chamber divided into sectors

Abstract

The invention discloses a partial top-bending correction mechanism for the inner wall of a movable vacuum chamber, which includes a support base, a guide rail, a vertical fixing system, a guide system, a positioning system, a drive system and a hydraulic system. The support base is fixedly arranged on The inner wall of the vacuum chamber is divided into sectors; the track is fixedly arranged on the support base; the guide system includes a bottom plate and a steering body, the steering body is rotatably installed on the front and rear ends of the bottom of the bottom plate, and the steering body is movably arranged on on the track; the vertical fixing system is arranged on the steering body of the guiding system to limit the guiding system on the track; the positioning system is arranged on the steering body on one side of the guiding system to fix the guiding system on the track Above all, the present invention has a compact structure, and can quickly and accurately correct the inner walls of the sub-sectors of the vacuum chamber.

Description

technical field [0001] The invention relates to the technical field of a partial top bending correction device for a sub-sector inner wall of a nuclear fusion Tokkamak vacuum chamber, in particular to a local top bending correction mechanism for a sub-sector inner wall of a movable vacuum chamber. Background technique [0002] The vacuum chamber is an important part of the nuclear fusion tokamak. It has a large size, complex curved surface, and double-wall welding. The main manufacturing process is: firstly, a plurality of pre-bent and formed wall plates are assembled and welded into multiple sub-sectors. Then the whole vacuum chamber is welded by sector. Partial deformation will occur after the sector is welded. In order to meet the needs of the plasma-induced nuclear fusion reaction in the vacuum chamber, the vacuum chamber wall needs high shape accuracy, and the local deformation caused by welding needs to be corrected. [0003] The sectors of the vacuum chamber are bulk...

AI Technical Summary

Problems solved by technology

In the existing equipment, there is no automatic equipment, and most of them need to be completed by manual hammering, so it is difficult to guarantee its accuracy.

Usually, the correction range is limited after one positioning and clamping, and continuous correction cannot be performed on sub-sectors. The correction workload is heavy and the cost is high.
