在机械装配车间,需要把大量的丝对装配到机身、箱体等大型工件上。多数工厂是在风扳机上装一个带内螺孔的扳头,把丝对旋入工件。但在退扳头时,往往会出现把上好的丝对从工件中退出,扳头反而不能退出的情况。为了退出扳头,不得不反复旋进旋出,既浪费时间,又容易损坏丝对,给操作带来很多不便。一、原因分析丝对进入扳头与螺孔顶面接触后,扳头带动丝对旋转,把另一端旋入工件,直到与工件螺孔的底部顶紧为止。
In the mechanical assembly shop, the need to a large number of wire assembly to the fuselage, box and other large parts. Most factories are in the wind trigger mounted a wrench with a screw head, the wire into the workpiece. However, when pulling out the wrench, it is often the case that a good pair of wedges is withdrawn from the workpiece and the wrench can not be withdrawn. In order to exit the wrench, it has to be screwed in and out repeatedly, which is time-consuming and easily damaged. This brings a lot of inconvenience to the operation. First, the reasons Analysis of the wire into the wrench and screw top of the top of the contact, the wrench driven wire pair rotation, the other end into the workpiece until the top of the screw hole with the workpiece so tight.
