This design is the application of multi-process machining characteristics Combination Drilling, using a single setup and multiple hole drilling process. Fixture design also from the economical and practical to meet the processing requirements of the workpiece. Control system designed to meet the automated processing of the machine. In order to improve the efficiency of the production of automotive wheels, to meet the accuracy requirements of the parts to be processed, should adopt a combination of machine tools for machining. The combination machine is a lot of serialization, standardization of parts and a small number of specially designed components special special machine tools. Keywords: car wheel; fixture; hydraulic clamping; combination drilling machine;  目 录 TOC \o 3-3 \h \z \t 标题 1,1,标题 2,2   HYPERLINK \l _Toc324855442 前 言  PAGEREF _Toc324855442 \h 1  HYPERLINK \l _Toc324855443 1汽车轮毂零件分析  PAGEREF _Toc324855443 \h 2  HYPERLINK \l _Toc324855444 1.1零件图纸结构分析  PAGEREF _Toc324855444 \h 2  HYPERLINK \l _Toc324855445 1.2零件主要技术要求  PAGEREF _Toc324855445 \h 2  HYPERLINK \l _Toc324855446 1.3轮毂加工的现状和发展趋势  PAGEREF _Toc324855446 \h 4  HYPERLINK \l _Toc324855447 2.轮毂零件毛坯制造分析  PAGEREF _Toc324855447 \h 4  HYPERLINK \l _Toc324855448 2.1毛坯的铸造分析  PAGEREF _Toc3
