The Overall and Jig Design of Three-side Boring Modular Machine Tool for Cylinder Body of Diesel Engine
Abstract: The modular machine tool is based on serialization and standardization of the ponents of the standards, coupled with a small number of ponents, which is consisted of a special high productivity machine. It has such characteristics, high degree of automation , stable process quality, highly working procedure centralize. The subject design is a Three-side boring modular machining tool which processes water tank face, oil rind face and back cover board face of S195 cylinder body of diesel engine. The overall and jig design is important. Processed parts for cylinder block of S195 diesel engine, the tap of workpiece material is HT200, it bores 13 holes on the three faces, the workpiece is fixed one time, the three faces are processed at the same time. To meet the requirements of the design, process design is necessary. “Three plans and one card” is needed to be ascertained. The positioning model of machine tool is single working procedure horizontal modular machine tool, it is selected bore. According to the needs of technics process, it will analyse orientation and clamp methods of workpiece and design the necessary jig. The clampling means is hydraulic pressure clamping. The modular machine tool has such characteristics, low-cost, reliable work, simple structure , assemble and disassemble convenience, ease of maintenance and adjust, highly processing precision, easy to operate, reducing the workers’ labor
