The invention relates to the technical field of machining of oversized heavy gear rings, in particular to a tool for an oversized heavy workpiece and a machining process of the oversized heavy workpiece. The tool for the oversized heavy workpiece comprises a workbench, the workbench is provided with a working face and used for bearing the oversized heavy workpiece, a lifting appliance is arrangedon the workbench and comprises a center shaft, the center shaft is perpendicular to the working face and assembled on the workbench, a plurality of inhaul cables are assembled at the end, away from the workbench, of the center shaft, and the free ends of the inhaul cables are connected with the oversized heavy workpiece in a pulling mode. The machining process of the oversized heavy workpiece adopts the tool and comprises the following steps that the oversized heavy workpiece is assembled on the tool, and a machining device machines the oversized heavy workpiece. The technical problems that inthe prior art, the workbench cannot directly bear the ultra- oversized heavy gear rings, and after an expansion tool is additionally arranged, the expansion tool is prone to plastic deformation and plane distortion due to large stress are solved.

    本发明涉及超大重型齿圈加工技术领域,具体涉及一种用于超大重型工件的工装及超大重型工件的加工工艺。一种用于超大重型工件的工装,包括工作台,所述工作台具有工作面,所述工作台用于承载超大重型工件,所述工作台上设置有吊具,所述吊具包括中心轴,所述中心轴垂直于所述工作面装配在所述工作台上,所述中心轴的远离所述工作台的一端装配有多个拉索,所述拉索的自由端拉接所述超大重型工件。一种超大重型工件的加工工艺,采用上述的工装,包括如下步骤:将超大重型工件装配在所述工装上,加工装置对所述超大重型工件进行加工。解决了现有技术中的工作台无法直接承载超大型齿圈,增加拓展工装后,拓展工装易受力较大而发生塑性变形和平面扭曲的技术问题。
