螺钉与螺帽在任何一部机器当中,都占有相当的地位。装配时多用人工来上螺帽,这在生产飞跃发展,产品数量剧增的今日,就不适应了,相反的成为装配工作中的关键了。在这次“双革”运动中,我厂工人同志们改进成功了一套保险夹头。它利用电钻的动力进行工作,这不仅提高了生产效率,而且大大的减轻了工人的体力劳动。保险夹头主要由上锥体1、腰鼓形摩锥3和下锥体4等八个零件组成,其结构如图1所示。使用时,先将上锥体1的锥柄插入电钻的套管内,因此,当开动电钻后,上锥体1便随着转动。腰鼓形摩锥3在上锥体1和下
Screws and nuts in any one machine which occupy a considerable position. The assembly of artificial to the nut, which in the production of rapid development, the dramatic increase in the number of products today, do not meet, on the contrary became the key to the assembly work. In this “double leather” movement, our factory workers and comrades improved a successful insurance collet. It uses the power of electric drills to work, which not only increases productivity but also greatly reduces workers’ manual labor. Insurance chuck mainly by the cone 1, drum-shaped cone 3 and the cone under the cone 4 and other eight parts, the structure shown in Figure 1. When used, the taper of the upper cone 1 is inserted into the casing of the electric drill first, so that when the electric drill is started, the upper cone 1 rotates with rotation.
