在钴床或镗床等机床上更换钻头或镗杆时,通常都是用一楔铁先插入腰形孔中,再用鎯头敲打,才能使钻头或镗杆从锥孔中脱出。这种操作方法有许多缺点。为此,我厂设计了一种小装置,解决了传统操作方法中存在的问题。这种装置(见附图)由套圈、横销、弹簧片等零件构成。使用时将套圈套在钻床或镗床的主轴上,推至腰形孔处时,将横销通过套圈插入腰形孔内,为了防止脱落,卡入弹簧片,调整好间
When replacing a drill bit or boring bar on a machine tool such as a cobalt bed or a boring machine, a wedge iron is usually inserted into a waist-shaped hole first and then a beating head is used to release the drill bit or boring bar from the tapered hole. This method of operation has many disadvantages. To this end, I plant a small device designed to solve the problems existing in the traditional methods of operation. This device (see photo) consists of ferrules, cross pins, leaf springs and other components. When used, the ferrule is set on the spindle of the drilling machine or boring machine and pushed to the waist-shaped hole, the cross pin is inserted into the waist-shaped hole through the ferrule. In order to prevent falling off,
