在CN-120型载重汽车的离合器中,有一个分离拉杆回位弹簧如图1所示。因为弹簧的形状比较夏杂,所以过去加工过程中花费劳动量很大,工作效率很低。我厂试制工段孙德馨同志改进了一套工具,大大地减轻了体力劳动,比过去提高了工作效率30倍,而且盘出的弹簧质量完全合乎要求。盘弹簧工具的结构如图2所示。工作时,可把主休1夹在虎钳上,钢丝一端甲压板2压牢,伸出的尺寸L根据产品要求决定。再把推杆座5紧靠钢丝,
In the CN-120 truck clutch, there is a release lever return spring shown in Figure 1. Because the shape of the spring is more complicated, the amount of labor used in the past processing was large and the work efficiency was very low. Our plant trial section Comrade Sun Dexin improved a set of tools, greatly reducing manual labor, improve work efficiency than in the past 30 times, but also put the spring quality completely in line with the requirements. Disk spring tool structure shown in Figure 2. Work, the main break can be a clip on the vise, steel plate pressure plate 2 end firmly, extending the size of the L according to product requirements. Then push rod seat 5 close to the wire,
