An automobile actuating rod ball head is provided with a ball body and a mandrel coaxially connected with the end of the ball body, the ball body is a hollow ball body formed by welding two hemispherical bowls into a whole in a butt joint friction mode, and a protruding ring connected into a whole is arranged on the inner side of the butt joint position of the two hemispherical bowls. The convex rings are two parallel convex rings or convex rings with wave troughs. The mandrel comprises two sections of mandrels at the symmetrical ends of the sphere, the two sections of mandrels share the same axis, the axis penetrates through the sphere center of the sphere, and the two sections of mandrels are respectively connected with the top ends of the two hemispherical bowls into a whole to form the hemispherical bowls with the mandrels at the top ends. Firstly, a profile is forged or cast into a semi-finished product of a hemispherical bowl, the outer top end of the hemispherical bowl can be provided with an integrated core shaft, then the two hemispherical bowls are correspondingly placed on a friction welding machine in an opening-to-opening mode, butt-joint openings of the two buckled hemispherical bowls are welded together through the friction welding machine, and an integral hollow ball head blank is formed; and the outer surface of the hollow ball head blank is machined into a smooth ball surface. The hollow automobile actuating rod ball head is made of the same material and the same specification, the weight is greatly reduced, the strength of the ball head can be guaranteed, and the light-weight requirement of automobile parts is met.
汽车作用杆球头,有球体和与球体端部同轴连接的芯轴,球体为两个半球碗对接摩擦焊成一体的空心球体,两个半球碗对接处内侧带有连成一体的凸环。凸环是并列两个凸环或带有波谷的凸环。芯轴为在球体对称端的两段芯轴,两段芯轴共轴线,轴线穿过球体球心,两段芯轴分别与两个半球碗顶端连成一体,构成顶端带有芯轴的半球碗。先将型材锻压或压铸成半球碗的半成品,半球碗外顶端可以带有一体的芯轴,再将两个半球碗对口对应放在摩擦焊机器上,用摩擦焊机器将对扣两个半球碗对接口焊接在一起,构成整体的空心球头毛坯,再将空心球头毛坯球体外表面机械加工成光滑的球表面。这样形成空心的汽车作用杆球头,同材质同规格的球头,大大减轻了重量,还能保证球头的强度,达到了汽车零部件的轻型化要求。
