Mine Tunneling Achine bined Machine Tool Design
(Oriental Science &Technology College of Hunan Agricultural University, Changsha 410128)
Abstract: The design task is to develop mine tunneling machine parts processing technology, combined with bination process of drilling fixture design, the design of hydraulic control system, the design of the modular machine process in the process, through the production of bulk analysis of mine tunneling bined with a processing program, and to seek the best technology solutions, which illustrates the process in the importance of the production process; in bination process of drilling fixture design process, combined with the examples, introduces the fixture design method, especially for hole the processing precision is discussed; in the hydraulic control system design process, double sided drill hole modular machine tool as the object, on the basis of hydraulic system design of the basic principles, a reasonable hydraulic system diagram. The calculation of the main parameters of the system determine the ponents of the specification; bination of machine tool design process, combined with concrete examples and design experience, elaborated the general parts ( such as hydraulic slipway, the power box and so on ) selection and ponents ( such as the headstock ) design calculation.
Keywords: combination machine tool; hydraulic transmission; axle boxes; handicraft;drills clamp
