近几年来,发动机装配过程中,冷下轴承时夹钳很容易断裂,无论怎么焊接亦无法解决此问题,给工作带来麻烦,现将断裂原因及解决办法,在此作一简介。1 夹钳结构及断裂现象1.1 夹钳结构 夹钳主要由钳嘴、夹钳体和铆钉三部分构成,钳嘴与夹钳体用焊接方法连为一体,夹钳体相互间的转动由铆钉连接如图1所示。 In recent years, the engine assembly process, the cold under the bearing when the clamp is easy to break, no matter how the welding can not solve this problem, to work in trouble, now the cause of the fracture and solutions, here to make an introduction. 1 clamp structure and the phenomenon of fracture 1.1 Clamp structure The clamp is mainly composed of pliers mouth, clamp body and rivet three parts, pliers and clamp body with a welding method as a whole, the clamp body rotation between the rivets As shown in Figure 1.
