Automotive engine assembly line process flow introduction
The automobile engine is the whole heart of the automobile, and its manufacturing technology is the concentrated embodiment of the vehicle manufacturing technology. The process flow of automobile engine assembly line has a decisive influence on product quality. Therefore, in order to improve assembly quality and production efficiency, automobile manufacturers must analyze and study the whole process of automobile engine assembly line.
Automotive engine assembly line process is as follows:
1, the bottom face of the cylinder, cylinder, crankshaft, camshaft feeding, cleaning, blowing, diesel engine model, label printing.
2. After the cylinder body is turned over 180°, mark to confirm.
3. After the cylinder body is turned over, the bottom of the cylinder body faces up.
