In recent years , with the wide application of CNC machine tools, machining center, flexible manufacturing cell, flexible manufacturing systems and other modern processing equipment, the manufacturing method of the traditional mechanical processing of a major change, the fixture function from the past have been clamping, positioning, guide tool, into the clamping, positioning.Device processing function digital expansion, puts forward higher requirements for the rapid positioning, in the future the quick clamping fixture.
According to different classification, the fixture can be divided into many types,this design is mainly introduced in the shaft end groove milling fixture design,shaft groove milling fixture is a kind of machine tool fixture, which mainly comprises a positioning support element, clamping device, connection oriented elements, tool components or guide element, other devices or components,the six part of the clamp.
This article introduces the design of fixture development history, domestic and overseas research development, research background, purposes and classification. In addition, the design also makes a detail introduction on the shaft end groove milling fixture components and working principle.
The structure, size of the design with the traditional design method of the milling shaft groove clamp the overall structure and the various parts of the design. In addition, using three-dimensional mapping software Pro/ENGINEER on the shaft end groove milling fixture parts for 3D drawing and assembly drawing and parts drawing and assembly drawing of Engineering drawing. In addition, also the CNC programming and machining of blower punch with UG.
KEY WORDS: fixture, part drawing, design, engineering drawing, NC programming
