Movable mechanism for correcting local top bending of inner walls of vacuum chamber sectors

Abstract

The invention discloses a movable mechanism for correcting local top bending of inner walls of vacuum chamber sectors. The movable mechanism for correcting local top bending of inner walls of vacuum chamber sectors comprises a supporting base, a guide rail, vertical fixing systems, a guiding system, a positioning system, a driving system and a hydraulic system, wherein the supporting base is fixedly arranged on the inner wall of the vacuum chamber sector; the guide rail is fixedly arranged on the supporting base; the guiding system comprises a bottom plate and steering bodies; the steering bodies are rotatably arranged at the front end and the rear end of the bottom surface of the bottom plate and are movably arranged on the guide rail; the vertical fixing systems are arranged on the steering bodies of the guiding system and used for limiting the guiding system on the guide rail; and the positioning system is arranged on the steering body on one side of the guiding system and can fix the guiding system on the guide rail. The movable mechanism for correcting local top bending of inner walls of vacuum chamber sectors is compact in structure and can quickly and accurately correct theinner walls of the vacuum chamber sectors.

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 is large in size, complex in surface, and double-walled. Then the whole vacuum chamber is welded by sector. Partial deformation will occur after sector welding. In order to meet the needs of the plasma-induced nuclear fusion reaction inside the vacuum chamber, the inner wall of the vacuum chamber needs high shape accuracy, and the local deformation caused by welding needs to be corrected. [0003] The sectors of the vacuum chamber are bulky, and the area to be corrected is large. In the existing equipment, there is no automatic equipment, and most of them need to be completed b...

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.
