Problems solved by technology

[0004] Disadvantages of the existing technology: Since the body of the single-cylinder diesel engine is a gray iron casting thin-walled part, the quality and accuracy of the original boring is unstable, and the drilling template is used for drilling, which has low precision and low processing efficiency, and the drilling template needs to be moved back and forth and turned over and workpieces, the labor intensity of the operator is high
Especially with the development of light weight and energy-saving diesel engines, the wall thickness of the single-cylinder diesel engine body is becoming thinner, and the original processing technology cannot meet the processing requirements of the thin-wall body

Description

technical field [0001] The invention relates to a single-cylinder diesel engine body processing technology, which belongs to the field of diesel engine body production. Background technique [0002] The body of a single-cylinder diesel engine is a box processing part, which is an important basic part of the diesel engine. It plays a role in supporting and containing various transmission parts of the diesel engine. The quality of the body processing has a great impact on the accuracy, Both performance and lifespan have a direct impact. [0003] At present, in the field of single-cylinder diesel engine body processing, the processing methods of the body mainly include: rough milling, fine milling, rough boring, fine boring, and drilling template drilling. Radial drills or bench drills are generally used for drilling. [0004] Disadvantages of the existing technology: Since the body of the single-cylinder diesel engine is a gray iron casting thin-walled part, the quality and a...
