Introduction
The crankshaft is an important part of the automobile engine. It plays an important role in connecting the piston and the crankshaft in order to dissipate the energy generated by the combustion of the fuel in the engine. The crankshaft is usually cast by forging, and the end face is machined by precision grinding. With the development of automobile technology, the quality of the crankshaft end face has become more and more important.
Recently, automotive production companies have begun using a method called precision rolling for the machining of the crankshaft end face. Precision rolling is a kind of precision machining technology, which can achieve high-precision machining effect by combining rolling process with precision grinding. This technology can greatly improve the surface roughness and geometry accuracy of the processed parts. It has become an important technology for automobile production companies.
The objective of this paper is to study the influence of precision rolling technology on the quality of the crankshaft end face.
Theory
Precision rolling technology is a kind of precision grinding technology, which is mainly composed of two parts: rolling and grinding. The rolling process is in the form of rolling, while the grinding process is in the form of grinding. The crankshaft end face is processed in two stages by rolling and grinding.
The rolling process is mainly used to improve the surface smoothness of the crankshaft end face. The grinding process is mainly used to improve the geometry accuracy of the crankshaft end face.
In the precision rolling process, the rollers are used to press the end face of the crankshaft. The pressure applied to the crankshaft end face is uniform. The pressure will cause the crankshaft end face to deform plastically, and the pressure will cause the surface roughness of the crankshaft end face to decrease.
In the grinding process, the grinding wheel is used to further improve the geometry accuracy and surface quality of the crankshaft end face. The grinding wheel is a kind of abrasive tool with a relatively high hardness. During the grinding process, the part is subjected to a high pressure, and the part surface is subjected to a grinding effect.
Results and Discussion
In this section, the influence of precision rolling technology on the quality of the crankshaft end face is analyzed.
The shape of the end face of the crankshaft is an important factor affecting the quality of the crankshaft. The precision rolling process can effectively improve the shape accuracy of the crankshaft end face. The rolling process can reduce the unevenness of the end face, and the grinding process can further improve the shape accuracy. The combination of rolling and grinding can achieve a high shape accuracy of the crankshaft end face.
The stress of the crankshaft end face is also an important factor affecting the quality of the crankshaft end face. The precision rolling process can effectively improve the stress stability of the crankshaft end face. The rolling process can eliminate the internal stress, and the grinding process can further improve the stress stability. The combination of rolling and grinding can achieve a high stress stability of the crankshaft end face.
The size of the crankshaft end face is also an important factor affecting the quality of the crankshaft end face. The precision rolling process can effectively improve the size stability of the crankshaft end face. The rolling process can reduce the size deviation of the end face, and the grinding process can further improve the size stability. The combination of rolling and grinding can achieve a high size stability of the crankshaft end face.
Conclusion
From the above analysis, it can be concluded that the precision rolling process has a significant influence on the quality of the crankshaft end face. The rolling process can reduce the unevenness of the end face, eliminate the internal stress and reduce the size deviation. The grinding process can further improve the shape accuracy, stress stability and size stability of the crankshaft end face. The combination of rolling and grinding can achieve a high quality of the crankshaft end face.
In conclusion, precision rolling technology is an important technology for automobile production companies, and it is a necessary technology for improving the quality of the crankshaft end face.
