| Abstract: | Twist drills with exchangeable drill tips are a kind of new,highly efficient and internal cooling drills. Only drill tips are made of cemented carbide. In order to achieve the assembling,drill tips were designed to coordinate with drill rods in a special positioning and clamping way. In this paper,the principle of positioning and the characteristics of two types of drills are analyzed. A new kind of elastic clamping twist drill has been invented. Its structure is designed and modeled. Displacement and stress of the elastic structure is analyzed by the finite element software ANSYS. According to the analysis,the structure of drill rods and tips are designed and improved. |
