拧双头螺栓,一般都是用双螺帽对紧,将螺栓拧入。但对于成批大量生产的机械装配,这种方法就不适应。另外,虽然还有些其它各种各样的方法,但其中有的还存在着不同程度的问题,用起来不够理想。为了解决这个问题,我们设计制做一种快速拧M24双头螺栓工具(附图)。这种工具结构简单,制做容易,使用方便、可靠。同时也不会损伤螺栓。由于外筒1和内筒7用大导程方牙双头螺纹连接,所以,传动灵活、效率高。并且由于螺纹导程增 Double-headed bolt, usually with a pair of nuts on the tight, the screw into. However, this method does not adapt to the mass production of mechanical assembly. In addition, although there are some other various methods, some of them still have different degrees of problems and are not ideal for use. In order to solve this problem, we designed a quick twist M24 stud bolt tool (with photos). The utility model has the advantages of simple structure, easy manufacture, convenient and reliable use. At the same time it will not damage the bolt. As the outer cylinder 1 and the inner cylinder 7 with a large lead square tooth double thread connection, so the transmission flexible, high efficiency. And due to thread lead increase
