Abstract
The CA6140 lathe is widely used in the machining industry as a primary turning machine tool. The main function of the CA6140 lathe spindle box is to support and drive the spindle, allowing the lathe spindle to rotate the workpiece at a predetermined speed. Based on literature research, online research, and market research, this design uses calculation, analogy, and experimental methods to determine the motion plan and structural design. By applying functional design and calculation, Solidworks 3D software is used to complete the modeling and assembly of parts, 3D structural and styling design, and the creation of part and assembly layout drawings, achieving dynamic assembly display. The overall structure and characteristics of the components, shapes, dimensions, and assembly features of the adjusted spindle box are visually represented, and the internal structure and working principle of the CA6140 lathe spindle box are vividly expressed through 3D animation explosion and working motion simulation, making it easy to understand. The use of 3D CAD technology to create parametric models enables the optimization design of the lathe spindle box, reducing design time and improving product development design efficiency.
