Automated production line for differential casings
The differential case automated production line, designed and manufactured by Beijing Shenming Technology Co., Ltd., uses articulated robots for loading and unloading. By using articulated robots and CNC lathes in conjunction, it simulates the path of manual tool loading and unloading, enabling the curved cutting tool for machining the hemisphere to automatically perform cutting and retracting actions, thus overcoming the traditional difficulties in machining hemispheres. Its advantages lie in reducing the procurement costs of equipment and tools, improving production efficiency, and achieving fully automated and unmanned production of differential cases.
As a core structural component of the vehicle's drive transmission, the automotive differential consists of left and right half-shaft gears, two planetary gears, and a gear carrier. Different vehicle models use different differential structures, with varying shapes and structures, generally classified into integral and split structures. From a machining perspective, integral differential cases are more difficult to machine.
In traditional machining of the hemispherical surface of passenger car differential cases, special umbrella-shaped cutters are typically used. The cutter is retracted when entering the inner hole, then opened to complete the machining after entering the hole, and finally retracted and withdrawn from the machining position after completion. This method requires no equipment modification, but the cost of individual tools is extremely high, leading to significant investment.
Another method involves modifying the lathe (lathe + rotary table) to use a curved cutter for machining this area. The rotary table and CNC system work together to control the cutter's movement and inner hole machining. This method involves high equipment modification costs. These traditional methods present insurmountable obstacles and increased costs to achieving automated differential case production lines.
Our innovation in this automated production line involves using a 2-axis general-purpose CNC lathe to reduce the cost of individual machines. By linking ordinary CNC lathes and robots, the curved cutter can Enter and machine the hemispherical surface. Furthermore, using lathes improves efficiency and reduces tool costs, allowing for compatibility with more products simply by changing the tooling. These innovations break away from the traditional concept of using only articulated robots for automated loading and unloading, making the production line more intelligent.
