"柴油机油泵体钻孔组合机床及夹具设计：工艺方案拟定与最优方案确定"

bstract.docx; The main content includes the formulation of the combined machine tool process scheme, the selection of the combined machine tool configuration type, the overall design, and the fixture design. In this article, the design of the combined machine tool and its special fixture consists of two main parts, one is the overall design of the machine tool, and the other is the design of the special fixture. The overall design of the machine tool includes the determination of the machine tool configuration form under the selected process scheme, the formulation of the structural scheme, and the determination of the "three drawings and one card" based on the formulated structural scheme, and the formulation of the fixture positioning scheme and the clamping scheme. Finally, through the comparison of the feasibility and operability of various design schemes, the best scheme is determined. In addition, it is necessary to reduce labor intensity and improve production efficiency through the design of special fixtures, and to ensure product quality through special fixtures.
