Title Combination tool design of the diesel Engine cylinder head injection hole processing
Abstract
Composed of common components and specially designed components ,
combination machine tool is high-efficiency special machine tool with processing one (or several) parts of one (or few) processes ,and at the same time ,has the applicability of general-purpose machine tool and the high efficiency of special machine tool ,widely used in machining with greater value and market prospects.
The design for the ZS195 diesel engine cylinder head injection hole processing combination machine tool is mentioned in this paper, including the design of cutting dosages, machine configuration form, fixture scheme tools, and the drawing and establishing of “three figure and a card” with parts process figure, processing schemes, machine tool contact size figure and machine tool production efficiency card included. The design of spindle box is also presented in this paper, and the assembly drawing of spindle box with the checking of parts .With this combination machine tool, the requirement of processing accuracy can be met, and at the same time, the production efficiency can be improved.
Keywords Combination machine tools technology “Three figure and a card” Spindle box Hole processing
