ABSTRACT
CNC Turn-minllling lathe is the symbol of the modern industrial development， It has basically realized the modernization requirements of high speed, high precision and multi-function; the essential part of which is the main component of this design is the main structure electric spindle. Its precision directly affects the machining precision of the machine tool. In order to meet the market demand, the manufacturing industry must develop more advanced, more personalized, and more self. The motorized electric spindle.
This design has completed the design of the electric spindle system, including the selection of the motor bearing and the calculation of the bearing life, the dimension of the spindle and the checking of the stiffness of the spindle strength, the assembly two-dimensional diagram, the main shaft part drawing and the box part drawing, the structure of the spindle, the flange, the spacer, and the nut on the spindle working line. And other components, in addition, we also designed the protection settings to ensure the normal operation of machine tools, sealing devices and labyrinth rings, and so on.
This design uses the two-dimensional computer design software AutoCAD to carry out the assembly drawing design of the electrical spindle component structure and the 3D modeling of the box by using the 3D design software SolidWorks. This design improves the machining accuracy of machine tools, realizes the high speed performance of machine tools, and fully embodies the technology of multi turn milling and milling.
