摘　　要：主要研究了对钻机卡盘夹紧机构中卡圈、碟形弹簧及卡瓦座的结构参数的改进。在分析夹紧机构的构成及工作原理的基础上,给出了碟形弹簧工作时的压缩量、提供的弹力大小、卡圈倾斜角、卡圈位移和卡瓦位移等多个参数之间的数学关系,进而重新选取了卡圈的倾斜角,重新设计制作了新型的加厚碟形弹簧,并做了新、旧碟形弹簧的承载性能的对比实验,表明新的加厚碟形弹簧效果良好。The improvement to the structure parameters of the collar, dish springs and gripping element of a drill chuck was discussed in this paper. Firstly, on the basis of the analysis on the structure and mechanism of the grip device, the mathematical relationship of the compression of the dish springs, the force of the springs, tilt angle of the collar, the displacement of both the collar and the gripping element were described. Then the tilt angle of the collar was selected, and a new design to the dish spring was made. Moreover, the contrast experiment to the bearing capacity of the new and the old dish springs was made. It was found that the behavior of the new dish spring is better than the old one.
