如图1所示的弹簧在加工质量方面要求比较高,需要量也很大。过去我们制造一件需要20多分钟,而且质量还不够好。后来经我厂机修车间钳工组同志改进了一个工具,使生产效率提高10倍,同时也保证了质量。工具的结构如图2所示。使用方法:首先将弹簧钢丝穿入螺母的孔内,然后卡在丝杆顶端的开口处。摇转手把则丝杆向左推进。当零件达到图纸要求时,钢丝的尾端正和刀头接触,由于弹簧直径突然增大,加上压紧螺钉的压
As shown in Figure 1, the spring in the processing of high quality requirements, the need is also great. In the past we made one need more than 20 minutes, and the quality is not good enough. Later, by our factory mechanic workshop fitter group comrades improved a tool to improve production efficiency 10 times, but also to ensure the quality. The structure of the tool shown in Figure 2. How to use: First spring steel wire into the hole in the nut, and then stuck in the top of the screw openings. Swing the hand lever to push the screw to the left. When the parts meet the requirements of the drawings, the end of the wire is in contact with the cutter head, due to a sudden increase in the diameter of the spring, plus the pressure to compress the screw
