汽车万向节滑动叉专用夹具设计 摘 要机床夹具是指在机械加工过程中，为了保证加工精度，固定工件，以接受加工或检测的工艺装备。机床夹具是一种不可缺少的工艺装备，它的设计直接影响加工的精度、劳动生产率和产品的制造成本等，在企业的产品设计制造以及生产技术装备中占有极其重要的地位。只有工件需要大批量生产时，商家才会选用专用夹具。专用夹具的设计，在一定程度上可以解决了现有夹具在工件大批量生产中的问题，从而提高了总体的生产效益。它同其他一般夹具一样包括定位装置、夹紧装置、夹具体。专用夹具的专用性强，操作迅速方便，是针对某一工件某一工序的加工要求而专门设计和制造的机床夹具，专用夹具的使用可以使产品相对稳定 、在大批量生产中可以获得较高的精度和生产效率，对工人的技术水平要求相对较低。本文为万向节滑动叉专用夹具的设计。它除了具有一般夹具的特点外，还有装夹简单，定位准确，不要找正，操作容易的特点。特别适合产品质量要求较高的大批量生关键词：机床夹具，定位装置，夹紧装置Gimbal sliding fork machining procedures and process equipmentABSTRACTMachine fixture means that the machining process, in order to ensure that the processing accuracy, fixed workpiece to accept processing or testing of equipment. Machine fixture is an indispensable technique and equipment, it is designed directly affect the accuracy of processing, labor productivity, and product manufacturing costs, in the enterprise product design and manufacturing as well as production technology and equipment occupies an extremely important position. Only when the workpiece needs of mass production, businessmen will use special fixture. Fixture for the design, to a certain extent, the existing fixture can be solved in the mass production of the workpiece, thus enhancing the overall production efficiency. He generally it with other positioning devices including the same fixture, clamping devices, specific folders. Fixture for dedicated strong, operation quickly and easily, is a part of a process fo...
