A new type of CNC boring and milling machine tool changer manipulator design and performance research

With the development of industry, the manipulator of CNC machine tools has been paid more and more attention in the machining industry. Compared with traditional machine tools, the machining center can complete a variety of processing more efficiently. It is obviously of great significance to study the tool-changing manipulator of the CNC machining center. The manipulator designed in this paper is a CNC boring machine tool changer manipulator, which realizes the tool change of the CNC boring and milling machine through the CNC cam and the mechanical arm structure. The time for completing a tool change is 2.5 s. The 'locking' and 'relaxation' states of the tool change are mainly completed by the top column, spring, and positioning the top column in the hook hand. The motion trajectory of the manipulator is realized by the double cam linkage structure of the spherical cam and the plane cam. The motion simulation of the manipulator is realized by the CAE motion simulation function of UG10.0.
