Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a welding mechanism for workpiece processing. Background Art

[0002] Welding is a workpiece processing method, and welding fixtures can accurately position and fix parts, so that parts maintain a stable position during the welding process, avoiding irregular welds or quality problems caused by movement. At the same time, the use of welding fixtures can make the entire welding process more automated, and operators only need to place and collect parts to improve work efficiency. However, the existing welding fixtures have limited angle adjustment capabilities, which reduces the practicality of the welding fixtures. At the same time, when adjusting the elevation angle of the clamping device, the adjustment gear needs to bear a large load, and the existing elevation adjustment gear lacks lubrication devices and lubricants. The direct contact between the gears will cause serious wear on the tooth surface and tooth top, increase the amount of friction generated, increase the transmission sound, and reduce the transmission efficiency.
