The process study of processing and the design of boring jig for the Engine bed headstock
Abstract
A country whether formidable, is mainly looked that this national industry to be whether developed. Now China still occupied the industrialization intermediate stage. China as early as located in the early 50s under the international situation, chose has given priority to the heavy industry in the path heavy industry majority products to process by the engine bed. The headstock body is engine bed's foundation, through it the engine bed main axle, the spare part and the engine bed joins in together. The headstock box body has the precision high plane and many Kong Xi must process, the working procedure content multi-craft route is long, its processing quality is deciding engine bed's assembly precision and the performance to a great extent. Under the major and medium volume production condition, processes in the example analysis to see massively, the craft plan consideration week, does not process the location not to be good, creates the processing mistake, work load increase doubled and re-doubled, the production cost rise. Conducts the research to the engine bed headstock body's technological process design question, to raises its use efficiency and the use quality has the significant practical significance. The engine bed headstock craft's analysis uses the working procedure to disperse, the working procedure centralized principle to optimize the processing craft the route, thus reduces the milling machine and the boring lathe jig installs the card the number of times, reduced unit clamp's design. Enables it to have in the processing process according to may depend on and enable it to have the summary experience and the theory basis. Provide the theoretical to other box body processing process study and the jig design basis.
