Abstract

The invention relates to the technical field of hydraulic cylinder welding, in particular to a welding device used for a hydraulic cylinder. The welding device used for the hydraulic cylinder comprises a mounting base. A first mounting groove is formed in one side of the mounting base, a clamping assembly used for clamping a shell to rotate is arranged at one end of the first mounting groove, anda hollow welding head is arranged in the first mounting groove. The two ends of the welding head are both communicated with the outside, a welding nozzle of the welding head is vertically arranged downwards, an adjusting piece used for adjusting the height of the welding head is arranged in the first mounting groove, a rectifier is fixed to the side wall of the mounting base, and a welding nozzleof the welding head is electrically connected to the rectifier through a wire. A second mounting groove is formed in the side, deviating from the first mounting groove, of the mounting base, and a conveying assembly used for conveying welding wires to the welding nozzle is arranged in the second mounting groove. The welding device has the effect of improving the welding quality of the hydraulic cylinder.

Description

technical field [0001] The present application relates to the technical field of welding of hydraulic cylinders, in particular to a welding device for hydraulic cylinders. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. [0003] In the process of manufacturing hydraulic cy...
