Description

Spherical supporting seat tool mechanism Technical Field The utility model relates to the technical field of supporting seat tooling mechanisms, in particular to a spherical supporting seat tooling mechanism. Background Clamping difficulties commonly exist in small and medium-sized iron castings and thin-wall steel castings processed by current companies. The fixed clamping method has the characteristics of small size deviation, irregular geometric shape, easiness in deformation of thin walls and the like, and the traditional fixed clamping method has significant challenges in practical application, on one hand, the rigid clamping is easy to cause workpiece deformation, particularly, the residual deformation of the front machining is superposed with clamping stress, so that the deformation accumulation effect in the finish machining stage is caused, the quality of a finished product is seriously affected, and on the other hand, the clamp is required to be frequently replaced when the workpiece with various specifications is faced, so that the production cost is increased, and the flexibility of a production line is reduced. More prominently, the operator needs to continuously carry out clamping adjustment in the processing process, which not only consumes man-hour, but also restricts the production efficiency.
