The Design of Drilling Four holes on the Diesel Engine Cylinder Cover bination Machine and the Desing of Hydralic Pressure System
Abstract
This paper introduces the bination machine working multiludinous spares,which is widely used for its high efficiency. This design task includes four parts: working out processing technology of drilling on the face of cylinder head, design and assemble of drilling jig, bination machine tool and design hydraulic control parts.
During process planning, define the productive process of drilling and find out the best process plan by analyzing production lot, which show process planning is very important in product process; this paper introduces experiences of attachment design by using a practical focuses on discussing how to improve the precision of hole position; using a single bore modular machine tool as an object, according to the basic principle of the hydraulic system design, formulates the reasonable schematic diagram, the hydraulic pressure part specification putation of the system main parameters is determined; Some designing examples are analyzed in this paper, and the considerations are discussed for posite tools for machining holes during bination machine tool, such as general parts’(hydraulic slippery platform, driving force box, etc) selection and special ponents’(main spindle box) design .
