The Research On The Key Technology Of An Enterprise TGDI Engine Manufacturing Process

The TGDI engine as the new engine, is used more and more widely, and the TGDI enginecylinder block, cylinder head, crankshaft, assembling and testing and other key manufacturingprocess, is to guarantee the quality of the product.This paper presents the application of existing engine cylinder block and head, as well as theproduct of an enterprise on the crankshaft manufacturing process based on TGDI key enginemanufacturing technology. First introduces the key technology of manufacturing differences, someenterprise existing products and TGDI products of existing product realization. Based on analysis ofmanufacturing technology of the existing products, propose the TGDI engine cylinder block,cylinder head, crankshaft, assembling and testing manufacturing key technological difficulties, fromthe processing precision of TGDI engine cylinder block, cylinder head, crankshaft key parts of theguarantee, cleanliness, tighten and leakage and other key process measures are discussed, theoptimization of TGDI engine cylinder block, cylinder head, crankshaft and assembling and testing,the key manufacturing process measures, effectively guarantee the product quality, improveproduction line flexible.Making full use of the present resources of an enterprise in the process of considering, throughthe analysis of existing models and TGDI cylinder block, cylinder head, crankshaft rough reference,the precise basis and excessive reference, put forward the existing models and the TGDI block, GangGai collinear production plan, quick change system by KPCS machining center fixture, can quicklyand accurately complete the product switch. Crankshaft line considering investment in the existingproduction line of large, high productivity, improve the existing curved axis transformation projectfor TGDI crankshaft, through the transformation of fixture, cutter and NC program production line.This thesis describes in detail the key technology of TGDI engine manufacturing and design ideas ofexisting products with TGDI engine production line and implementation measures.At the end of this paper, the TGDI engine cylinder block, cylinder head, crankshaft, assemblingand testing the key manufacture technology scheme, and connecting with the features of existingproducts, presents the solution of existing products and TGDI production line implementation.
