缸体工艺及钻M8底孔夹具设计(代做钻夹具毕业设计）
摘要：在机械加工零件时如果能广泛地使用夹具，就能极大地节省加工时的辅助时间，减轻工人的劳动量，提高产品的质量和劳动生产率。本文主要介绍了设计钻床夹具的的一般步骤和方法。设计夹具的一般先对原始资料进行分析，明确设计的要求和意图，然后提出具体的定位、夹紧、对刀方案和夹具体的一般结构。本文采用六点定位的定位方法，夹紧螺钉与双向压板组合的夹紧方法，直角对刀块与塞尺组合的对刀方法。为保证设计的可靠性，还对夹具的夹紧力和精度进行了分析。同时使设计基准与定位基准相重合，保证了槽侧面的加工精度与位置公差。随后，本文又对铣床夹具各组件的结构尺寸进行了明确的设计，并用UG三维软件对整个夹具进行建模和装配。该铣床夹具在设计之初就注重结构工艺性，所以这套夹具结构简易、紧凑，操作起来也比较方便灵活。更重要的是，它在提高生产效率方面所起的作用尤为突出，体现了这次设计的主旨。

Design of fixture
Abstract: in the mechanical machining if widely used fixture, can greatly save the auxiliary time processing, reduce the amount of labor workers, improve product quality and labor productivity. This paper mainly introduces the general steps and methods of the design of drilling jig. The fixture design of general first analysis of the original data, clear of the design requirements and intentions, and then put forward the specific positioning, clamping, tool programs and clip general structure of concrete. The six point positioning method, the clamping screw and two-way combination plate clamping method, the right angle knife block in combination with a feeler gauge cutter positioning method. In order to ensure the reliability of the design, the clamping force and precision of the fixture are also analyzed. At the same time, the design reference is coincident with the locating datum, which ensures the machining accuracy and the position tolerance of the side of the groove. Subsequently, this paper has made a clear design of the structure size of the milling fixture, and using UG 3D software to model and assemble the entire fixture. The milling fixture was designed from the beginning to pay attention to the structure process, so the structure of the fixture is simple and compact, the operation is convenient and flexible. More importantly, it improves the production efficiency in the role is particularly prominent, embodies the theme of this design.
Keywords: drilling machine, machine tool fixture design.
