螺栓的倒角和台肩的加工,过去是在三爪卡盘上分两步进行:1)用三爪卡盘夹牢进行倒角:2)在三爪卡盘上夹一个六角套,把工件装在六角套内,然后用反顶尖顶住进行台肩的加工。这种方法的主要缺点是:劳动量大,生产率低。由于我们生产螺栓的批量相当大,如果还采用老方法加工,就不能满足装配的需要。所以,车工彭大生同志积极动脑筋、想办法、改进了一个加工螺栓台肩和倒角用的工具。用这个工具可以减轻劳劫,并能显著地提高生产率。
Bolt chamfering and shoulder processing, the past is in the three-jaw chuck in two steps: 1) with a three-jaw chuck jacketed chamfer: 2) in the three-jaw chuck clip a hexagonal set, the The work piece is housed in a hexagonal socket and then topped off with a counter top to allow for shoulder machining. The main drawbacks of this approach are: heavy labor and low productivity. Due to the considerable volume of our production bolts, the assembly needs can not be met if the old method is also used. Therefore, the caravan of Comrade Pang Dasheng actively brains, think of a way to improve the processing of a bolt shoulder and chamfering tools. Using this tool can reduce labor costs and significantly increase productivity.
