车床三爪卡盘历来靠手动扳紧,既浪费时间,劳动程度又大,近年来,许多同志一直在考虑改变这种卡盘。去年,在批林整风运动的推动下,我们上海机床厂二车间车床二段的工人同志在学习兄弟厂经验的基础上,应用一齿差行星减速机构的原理,搞成了240毫米车床电动卡盘。过去用钥匙手动扳紧,现在只要按一下按钮就将零件夹紧,实现了装夹自动化,大大 Lathe chucks have traditionally been manually tightened, which is a waste of time and labor. In recent years, many comrades have been considering changing such chucks. Last year, under the encouragement of the forestry rectification movement, the comrades of the second lathe of Shanghai Machine Tool Works No.2 Workshop used the principle of a planetary planetary gear-reducing mechanism to develop a 240 mm lathe power card on the basis of the experience of the brother factory. plate. In the past, manual tightening was performed with a key, and now only a click of a button is required to clamp the parts and automation of mounting is achieved.
