ABSTRACT
This paper chooses the manufacture and processing of titanium alloy joint as the research object,which is an important part of the machine part, its role is the body and the body connection. The parts are titanium alloy, complex shape, high precision aperture on the parts, hole size requirements of strict, and interrelated, coordination requirements, processing difficulties.
The main research contents of this paper are the high speed machining technology and fixture design of TC4 titanium alloy joint. The machining process of the eccentric shaft is machined, and the machining allowance is selected in detail. The machining allowance is selected in detail, such as machining allowance, cutting amount, size tolerance, determination of each process size, process processing allowance, processing time and machining. Through this design master parts of the processing process analysis, process card preparation and steps. Learn the application manual, standards, norms and other information. Recognize the importance of technology in machinery manufacturing. Understand the rules of selection of tools, product quality, accuracy, life and other properties and save materials, reduce costs, the most important thing is to improve production experience.
Through the discussionwith the teacher decided to design and processingФ12 hole dedicated drilling fixture, the design content positioning and clamping program to determine the positioning components and clamping components selection, the design of the clip, the calculation of drilling force and so on.
Keywords TC4 titanium alloy, joint, high-speed processing, technology, processingФ12 hole
