The length of the power station is designed according to the field environment of the power station and is different in length. If a large boring machine with broad-spectrum adaptability (with a long guide rail) is adopted, the cost is extremely high. Therefore, under normal conditions, a common boring machine is used for machining. When a common boring machine is used for machining the shell, the length of each product is different, so that a workpiece to be machined is positioned outside a numerical control boring machine workbench and needs to be fixed by a movable support for post-machining. The mobile support requires adjustment of position according to workpiece length changes and recalibration. After the movable support is adjusted each time, the support needs to be corrected, and the correction precision consistency cannot be guaranteed; the movable supporting position needs to be manually adjusted and corrected according to the change of the length of the workpiece, so that long time needs to be consumed, and the production efficiency is low.
