[0002] As a tooling for a specific purpose, the internal support tooling is designed and applied mainly for working environments that require internal support or fixation. The internal support tooling is a type of tooling fixture. Its principle is to clamp and fix the workpiece through the internal support structure so that it can maintain a stable posture for processing, testing or other operations. In the process of processing the cylinder, it is usually necessary to use an internal support tooling to provide auxiliary support for the cylinder.
