ABSTRACT
Basic design the design of special fixture pipe base parts machining process. The main chassis parts through the pipe surface roughness, the hole processing. In general, ensure easy than guarantee precision machining precision holes. Therefore, the design principles of the first hole surface. Hole machining plane is divided into distinct stages to ensure the rough machining and machining precision machining hole. On the basis, through the input shaft and the output shaft hole of the bottom surface as the basis for a good basic reference process pipeline. The main flow arrangement is supported in the positioning hole of the first, and then the processing hole plane and the hole positioning technology support. In a subsequent step, in addition to being positioned in the processing technology of the top plane and holes and other holes separate process. The whole process is a combination of the selection tool. Special fixture fixture selection, a self-locking mechanism, therefore, higher productivity, for large quantities, to meet the design requirements.
