The invention relates to a welding forming process of an axle tube for a cab turnover mechanism and an assembly thereof. The welding forming process of the axle tube for the cab turnover mechanism mainly comprises: S1, preparing a spline and a sleeve to be welded to the spline; and S2, selecting a friction welding machine, placing the spline and the sleeve in the friction welding machine for friction welding, and obtaining the axle tube by forming. The cab turnover mechanism assembly comprises the axle tube manufactured through the process; the axle tube is sequentially provided with an axle tube welding assembly, a fixed frame mechanism and an axle tube adjustment arm assembly from the middle to the end; and the fixed frame mechanism comprises a support linked with the axle tube, and a damping rubber assembly placed between the support and the axle tube. The welding forming process of the axle tube for the cab turnover mechanism and the assembly thereof have the beneficial effects that the axle tube is free of cracks and air holes, materials at the welding position are uniform, the connecting strength is high, and the assembly adopting the axle tube is higher in structural stability and higher in safety performance.
Description
technical field [0001] The invention relates to the technical field of cab overturning assembly equipment, in particular to a welding and forming process for a shaft tube used in a cab overturning mechanism and its assembly. Background technique [0002] An important part of the cab truck and special vehicle body is the place where professional drivers work day and night. Its structure is directly related to the driver's safety, work efficiency and health. The frame is flexibly connected and does not bear load. It belongs to the non-load-bearing body. The bottom of the cab is equipped with a turning mechanism, which is convenient for the staff to adjust. [0003] The overturning mechanism assembly mainly includes: a support group, the support group is composed of a support and a shaft tube (torsion bar), wherein the shaft tube is mainly composed of a spline and a sleeve, and welders are generally welded by welding torches This welding method is easy to have welding slag and...
