Modular machine tool and special fixture design
Abstract:The graduation project task is to understand the structural characteristics and the advantages and disadvantages of the combination of machine tool and fixture design content and related data, complete the crankshaft end milling to center punch combination machine tools and special fixture design, and the design of the subject, to improve their theoretical Contact practical and comprehensive analysis, training the mechatronics design capabilities; establish a modern design concepts to improve the basic skills of computer-aided design and access design data, standards and norms.
The process of the crankshaft Part crank spindle centerline location request, processing to the hair two spindle cylindrical surface positioning the first end milling machining center hole, after coarse positioning of both end surfaces of the center hole, finishing each axis the surface, and finally coarse and fine grinding of the journal.
In the design process of the jig, the crankshaft in the V-shaped block and positioning pins to locate, with the rotary platen clamping. Hydraulic clamping mechanism for clamping fixture.
Key Words：Crankshaft machining; Modular machine tool design; Special fixture design
