Problems solved by technology
[0003] For the traditional processing methods with this characteristic, most of the parts are clamped by using three jaws with a large contact area. Due to the large shape of the part (φ500mm) and the thin wall thickness (2mm), it is easy to deform during turning and needs to be repeated. Calibrate the center position of the part before processing, the production efficiency is very low, and it is difficult to ensure the stability of product quality

The invention relates to a turning tool for casing shell parts. The turning tool comprises a disc-shaped base, wherein a workpiece is assembled on the base, a center positioning adjusting mechanism isarranged in the center of the base, a plurality of linkage positioning mechanisms are evenly arranged on the inner wall of the workpiece in the circumferential direction at intervals, and a pluralityof auxiliary supporting clamping mechanisms are arranged on the outer wall of the circumference of the workpiece at intervals; and a rotating direction positioning block is arranged between the two auxiliary supporting and clamping mechanisms. According to the tooling tool, positioning devices capable of being flexibly adjusted are introduced, so that machining of parts of various specificationscan be achieved through adjustable center positioning shafts and three cooperative linkage positioning devices which are evenly distributed, and the positioning precision is high; and six auxiliary supporting devices on the outer wall of the parts can guarantee uniform distribution of pressing force, deformation of the parts caused by the pressing process is avoided, and the stable product qualityis guaranteed.
Description
technical field [0001] The invention relates to the field of tooling technology, in particular to a turning tooling for machine casing parts. Background technique [0002] Such casing parts are mostly large thin-walled parts made of high-temperature alloy Inco625 material, which are used to connect and support other key core components in high-temperature and high-pressure environments, and are widely used. The precision of the tolerance of the mouth of the part is high, and it is used for welding and assembling after assembly with the counterpart. It is very important for the accurate realization of the assembly function of the part, and it is a common feature of this series of products. [0003] For the traditional processing methods with this characteristic, most of the parts are clamped by using three jaws with a large contact area. Due to the large shape of the part (φ500mm) and the thin wall thickness (2mm), it is easy to deform during turning and needs to be repeated....
