Abstract

The invention discloses a spot welding method for a vehicle suspension control arm. The spot welding method comprises the following steps of arranging a longitudinal adjustment plate on a base; arranging a transverse adjustment plate on the longitudinal adjustment plate; arranging a vertical support air cylinder on the transverse adjustment plate; arranging a suspension plate on the piston rod ofthe vertical support air cylinder; arranging a clamping arm I and a clamping arm II for tightly clamping a top cover and a bottom cover of the vehicle suspension control arm, on the suspension plate;connecting an electro-pneumatic proportional valve with the vertical support air cylinder for adjusting the air inflow of the vertical support air cylinder, so that when spot welding is performed eachtime, the whole body formed by the suspension plate, the clamping arm I, the clamping arm II and the vehicle suspension control arm is in a suspension state by adjusting the air inflow of the vertical support air cylinder through the electro-pneumatic proportional valve after a concave welding spot on the top cover and the bottom cover which are tightly clamped together moves to a location between an upper electrode and a lower electrode; and performing spot welding through the downward movement of the upper electrode.

Description

technical field [0001] The invention relates to a welding method, in particular to a spot welding method for an automobile suspension control arm. Background technique [0002] Suspension system is an important assembly in modern cars, which has a great influence on the ride comfort and handling stability of the car. As a guide and force transmission element in the automobile suspension system, the control arm is used to transmit various forces acting on the wheels to the body, and at the same time to ensure that the wheels move according to a certain trajectory. The control arm connects the wheel and the body elastically through ball hinges or bushings, respectively. In actual working conditions, the control arm should have sufficient rigidity, strength and service life. [0003] like figure 1 As shown, an existing vehicle suspension control arm includes a top cover 1 and a bottom cover 2, end holes 3 are provided at both ends of the top cover 1 and the bottom cover 2, an...
