The design of Block entitled rocker shaft technology and equipment design and CAD / CAM From Chaoyang Diesel Engine Company LThis is designed to complete the 195-seat rocker shaft diesel engine mold design， Rocker Shaft Tower card processing routes and the development process， some special fixture design Three-dimensional modeling software Pro / E into the mold of its design， including: the construction of a module with parts and blank parts of the solid model; on the part of the investment casting mold design， including sub-surface， injection system， pushing pieces of bodies， punch and die， mold base， ， with engineering drawings and CAXA electronic board module to complete the mold assembly Order to develop machining technology， including process selection， process development line， the determination of machining allowance， and then calculated according to the technical point of order parameters and the appropriate technology to produce the Special milling fixture design， 2 sets of special drilling jig 1 set: the analysis， selection and design， the use of CAXA electronic drawing board to complete its work The design of the difficulties is the fixture and die， in the access to a wealth of information and very good teachers under the guidance of the final settlement of these issues， the successful completion of the
Abstract In order to improve China's railway freight capacity， and can better adapt to the existing railway line bridge， the actual state of development of load 70t， axle load 25t new GM vehicle has become an important 70t class in this new type of general goods on behalf of the C70-type models based on the general development of the gondola car design high side gondola car， named C70GB High side gondola car C70GB Department of General gondola car， the vehicle for the quasi-gauge railway in China， big shipment of goods， or the proportion of small goods in bulk， can be used for self-organization of fixed rail In a given vehicle performance and size parameters of the main conditions， the completion of the overall vehicle design and large parts， including chassis， side wall， side walls， doors and other structures， as well as the hook relief device， the selection of the Combination of design requirements on goods 70t-class key technologies and design ideas， including the lightweight body design， 25t axle load bogie Pre-design work of the main research process， analysis of issues in program selection and design， and finally through the computer graphics software to complete the overall design of vehicles and parts， in this paper based on the combination of drawing and calculation of theoretical analysis and presentation of Through the introduction of new materials， new technologies and new structural design C70GB from the high side gondola car technology to improve vehicle performance， increase rail freight capacity， China has laid a railway truck load 70t from 60t-class upgrade to the basic Keywords: gondola car; technical parameter; structure; bogie
The theme of this design is the design， together with its CAD/CAM， of the process and tooling equipment for the rocker shaft bed This design task is from Chaoyang Diesel Engine C， L The purpose of this design is to complete the mold design work for the rocker shaft bed of 195 Diesel Engine， the design of the process flow and process cards for the development of the rocker shaft bed， and the design of some special fixtures for certain We used the Three-dimensional modeling software Pro / E to complete the mould design work， including the modeling work of the parts and blank parts using the part module of the software; the design work of the Investment Casting mold， including the parting surface， the injection systyem， the ejection mechanism， the convex and concave mold， mold base， Completed the mold assembly drawings with engineering drawings module of Pro / E and CAXA Made out the process plan for the part development， including the processing methods， the processing route， the determination of machining allowance， and then calculated the process parameters according to the process plan to produce the process We designed two sets of special milling fixture， one set of special drilling After analysing， selecting， and design， we finished its engineering drawing with CAXA The difficult points of the design are the moulds and We finally solved these problems via a large amount of research work and the teacher's assistance， and successfully accomplished this design Keywords: solid modeling; mold; fixture; technique 完全是自己翻译的，我是搞机械设计的，学习了。谢谢楼主提供的翻译练习机会。
