在装配和检修轮铀工作中,经常需要研修钩头键。以前拔钩头键都采用锤打或杆子撬,这样作的缺点是可靠性差,麻烦、生产效率低,而且经常敲打容易碰坏轮、轴和键等零件,为了克服这一缺点,我们搞了这种拔钩头键的工具。它的结构很简单,整个工具只有七个零件(见图)。钩头1和螺杆3可在本体4的滑道中自由滑动。使用时,只需把该工具放在轴上,使本体4烧铜焊的一端紧靠轮子的端面,让钩头1卡住钩头键,然后用普通板手旋 In the assembly and maintenance of uranium work, often need to study hook key. Before pulling the hook keys are used hammer or pole pry, so the disadvantage is the poor reliability, trouble, low productivity, and often beat easy to damage the wheel, shaft and keys and other parts, in order to overcome this shortcoming, we engage in This hook the first key tool. Its structure is very simple, the entire tool only seven parts (see photo). The hook head 1 and the screw 3 can slide freely in the slideway of the body 4. Use, simply put the tool on the shaft, so that the body 4 brazing end close to the wheel end face, so hook head 1 stuck hook head key, and then use the common board hand
