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

Abstract

The utility model relates to a seam welding machine for automatically welding the base of an oil storage cylinder of an automobile shock absorber, which belongs to the technical field of resistance welding equipment and is used for welding the oil storage cylinder and the base of the automobile shock absorber. The technical solution is: the welding transformer is installed inside the welding machine body, the welding controller is installed in the electric control box, the rotary table is located at the front and bottom of the welding machine body, the seam welding wheel driving mechanism is installed above the welding machine body, and the seam welding wheel The two output shafts of the driving mechanism are respectively connected with the left driving wheel pressing assembly and the right driving wheel pressing assembly. The pressing mechanism is installed in front of the welding machine body. The assembly and displacement detection mechanism are all installed in the pressurizing mechanism, the water blowing device is installed in the front, lower and left side of the welding machine body, the cooling water tank assembly is placed in the lower and rear of the welding machine body, the electric control box is placed in the rear of the welding machine body, and the water circuit The assembly and gas circuit assembly are installed on the left side of the welding machine body. The invention greatly improves the automation level and improves the production efficiency.

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
