Holes Abstract This design instruction booklet mainly aims at the ponents of 4135 diesel engine cylinder block to design special purpose machine of drilling the index hole. In which mainly in dudes that the processing technological process which designed according to the detail drawing and the production guiding principle。 various parts’ designing of special purpose machine, the key is the headstock’s designing as well as the unit damp’s designing, this instruction booklet has made the detailed putation and the explanation to these contents. Meanwhile, elaborated how to draw up the working procedure chart of drilling the index hole on air went cylinder body, processing schematic drawing, the relational dimensional drawing of the special purpose machine of drilling the index hole, headstock developed view, the unit clamp chart in the foundation of designing and calculation, as well as the question which should be pay attention in the cartography. At present, Special machine tool industry production and marketing, are on the rise, Special machine quality, technical content also gradually with the level of world other manufacturing power. China39。s current is a manufacturing power, still cannot call manufacturing power. To make our country by actual manufacturing power into manufacturing power, machinery industry responsibility is significant. Of course as a machinery industry special machine tool industry is no exception. Special machine tool industry to launch a torchplan, conquer the current industry enterprise technology development problem。 Secondly, to strengthen and foreign joint venture cooperation, utilization and learn foreign advanced technology, improve the modern enterprise management level and technical level。 Thirdly, based on the imported technology before the digestion and absorption of innovation, develop their own products. Developing special machine tool industry also has certain difficulty: because it is sets processing technology, the machine tool39。s fixture, props, cutting tools, measuring and testing, logistics is equal to one, achieve III turnkey project, which involves technology is plex, wide and is onetime manufacturing, to ensure a success, so the technical difficulties, etc. Key words Headstock Jig Technological process 目 錄 中文 摘要 ............................................................
