Description

Technical Field

[0001] This utility model relates to the field of cylinder rotary welding technology, and in particular to a rotary welding device for hydraulic cylinder bodies. Background Technology

[0002] Hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy and perform linear reciprocating motion. They have a simple structure and reliable operation. When used to achieve reciprocating motion, they eliminate the need for a speed reduction device and have no transmission backlash, resulting in smooth movement. Therefore, they are widely used in the hydraulic systems of various machines. When assembling the cylinder body, a hinge joint welding operation is required at the end of the cylinder body. Currently, welding the hinge joint to the cylinder body requires a welder to hold a welding torch and weld the hinge joint to the cylinder body. This method involves a large workload for the welding operator and low welding efficiency, which cannot meet the needs of welding the hinge joint to the cylinder body. Utility Model Content
