Manufacturing Technology and Fixture Design of Drill Mandrel
[Abstract] This design includes mechanical manufacturing process, process and fixture design, lathe drilling, milling, grinding and other knowledge.
The manufacturing process of drill mandrel includes part of process design and process design. In the process design, the specific technical requirements are analyzed, such as the use and the specific size and shape first, then the structure of the billet is analyzed and processed, and the processing datum of the selected part is processed, then the route technology of the processed part is processed, and then the process and cutting quantity of each process are determined by the step-by-step calculation in the process. Finally, a special fixture for V-shaped surface milling is designed.
