套零件加工工艺及钻孔夹具设计（有CAD图纸）.pdf

: [Abstract] Set of parts machining technology and the design of drilling jig design, including design process is machining process design and the three part special fixture. In the process of design should first of all parts to analyze, understand parts of the process and then design a blank structure, and choose the good parts machining datum, designs the process routes of the parts; then the parts of each step process dimension calculation, the key is to determine the process equipment and cutting the amount of each working procedure; design then a special fixture, fixture for the various components of the design, such as the connecting part positioning device, clamping device, a guide element, clamp and the machine tool and other components; the positioning error generated when calculate fixture positioning, analysis of the rationality and deficiency of fixture structure, pay attention to improving and will design in. Keywords: process, process, cutting parameters, clamping II
