摘　　要：针对某汽车前轴两端钻孔大小不一且无法保证对称性而造成次品率较高的问题,设计了一种专用钻床夹具。其采用一面两销的定位和绞链夹紧机构,并对加工精度进行了理论研究计算。结果表明,该设计满足使用要求且在大批量生产中能够获得较高的精度和生产效率。According to the problems of on both ends of automobile front axle drill hole different sizes and it can＇t guarantee symmetry leading to higher defective rate,this paper put forward a plan for the design of a special drill jig.It uses a two pin positioning scheme and hinge clamping mechanism,and theoretical research calculating for positioning force and analysis of fixing error.The result shows that the design meets the need of getting higher precision and production efficiency in the batch larger production.

关 键 词：钻床夹具 定位 加工精度
