Abstract: |
This paper introduces the composition of large diameter clasp for solid rocket motor, connection form of clasp and the engine, selection of materials and technical requirements. According to the structure and process characteristics, process difficulties are analyzed and the corresponding measures are presented. A new turning method is proposed and described from the turning principle of screw thread machining method and a series of technology methods of thread profile, pitch, turning tools, starting and end position of the tool while turning, and grinding molding process. This method not only saves time and effort, and guarantees the accuracy. |
