汽车卡钳加工工艺及柔性组合夹具设计+CAD图纸
本课题括零件加工工艺分析，制动钳夹具装夹方案的制定，基于UG的零件装配。在工艺分析中要首先对零件结构尺寸特点进行分析，并选择零件的加工基准。接着对零件各个工步的工序进行尺寸计算，关键是决定出各个工序的工艺装备及切削用量。然后进行柔性组合夹具设计，选择并设计出夹具的定位元件、夹紧元件、引导元件、夹具体与机床的连接部件以及其它部件；通过有限元分析确定零件在加工过程中的精度影响、夹具布局的合理性与不足之处，并进行优化。
汽车卡钳数控加工工艺及柔性组合夹具设计这个课题将零件的分析、加工工艺的选择与制定、夹具的设计整合在一起。在设计过程中，需要考虑到零件的结构特点分析、工艺的合理性、机床的选择、加工的成本高低、夹具的布局、定位与夹紧是否可靠等等。这个课题基于UG和AutoCAD对夹具进行计算机辅助设计。7092

Car calipers CNC processing technology
and flexible modular fixture design
Abstract: The object of this research for the automotive caliper CNC machining technology and flexible modular fixture design. First, because the braking action is to finalize the caliper clamp body, and its importance is self-evident. So it can be said caliper brake system is a key component.
This topic includes parts machining process analysis, the brake clamp with clamping program development, UG-based parts assembly. In the process of analysis would be the first structural dimensions of the parts analysis of the characteristics and select parts of the processing benchmarks. Then step on the part of the process for each size calculation, the key is to determine the various processes of technical equipment and cutting. Flexible then combined fixture design, selection and design of the fixture positioning element, the clamping element, the guide member, the machine specific folder and other parts of the connecting member; parts by finite element analysis to determine the precision in the process of impact fixture layout rationality and shortcomings, and optimization.
Automotive caliper CNC machining technology and flexible modular fixture design the part of the subject analysis, selection and formulation process, fixture design together. In the design process, need to be considered part of the structural characteristics analysis, process is reasonable, machine selection, processing and low cost, fixture layout, positioning and clamping reliability and so on. This topic is based on the fixture UG and AutoCAD computer-aided design
Keywords: calipers, digital processing technology, the flexible modular fixture.
