Seam welder for automatically welding oil storage cylinder and base of automobile damper

Abstract

The invention discloses a seam welder for automatically welding an oil storage cylinder and a base of an automobile damper and belongs to the technical field of resistance welding equipment. The seamwelder is used for welding the oil storage cylinder and the base of the automobile damper. According to the technical scheme, the seam welder is characterized in that a welding transformer is installed inside a welder body; a welding controller is installed in an electric control box; a rotating worktable is located on the lower-front portion of the welder body; a seam-welding wheel driving mechanism is installed on the upper portion of the welder body; two output shafts of the seam-welding wheel driving mechanism are connected with a left driving wheel compression assembly and a right drivingwheel compression assembly correspondingly; pressurizing mechanisms are installed in front of the welder body, and the left driving wheel compression assembly, the right driving wheel compression assembly and a displacement detecting mechanism are all provided with the pressurizing mechanisms; a water blowing device is installed on the left side of the lower-front portion of the welder body; a cooling water tank assembly is placed on the lower-rear portion of the welder body; the electric control box is placed behind the welder body; and a water channel assembly and an air channel assembly are both installed on the left side of the welder body. The automation degree is promoted greatly, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a seam welding machine capable of automatically welding the base of an oil storage cylinder of an automobile shock absorber, and belongs to the technical field of resistance welding equipment. Background technique [0002] The diameter of the oil storage tank of the automobile shock absorber is 30mm-55mm, and the wall thickness is 1mm-2mm. The base is pre-pressed on the end of the oil storage tank. It is required to perform a tear test after welding. The width of the tear strip is ≥1.5mm; compression resistance The strength is ≥40KN, and the verticality of the base relative to the oil storage cylinder is 0.3mm. At present, there are two kinds of welding machines for welding the oil storage tank of automobile shock absorber on the market. One is to use the pneumatic clamp type to realize automatic centering when the diameter of the workpiece changes, but the centering effect is not ideal, and there will be cracks during welding....

Problems solved by technology

At present, there are two kinds of welding machines for welding the oil storage tank of automobile shock absorber on the market. One is to use the pneumatic clamp type to realize automatic centering when the diameter of the workpiece changes, but the centering effect is not ideal, and there will be cracks during welding. Swing phenomenon; the other is the cylinder direct pressure type, but it cannot automatically adapt to changes in the diameter of the workpiece and the diameter of the seam welding wheel, and the operator needs to often adjust the initial position of one end
