Description

Technical Field

[0002] When multi-angle welding is performed on a larger workpiece, because the workpiece itself is large in size, workers need to move continuously during the welding process to achieve multi-angle welding of the workpiece; or additional manpower is required, and multiple workers are required to weld one workpiece. The entire welding operation is time-consuming and labor-intensive, and the production cost is high. CN 220312341U discloses a welding two-axis positioner, including a welding mounting plate, a first driving mechanism that drives the welding mounting plate to rotate around its central axis, and a second driving mechanism that drives the first driving mechanism to swing; the second driving mechanism includes a second rotating shaft arranged on opposite sides of the mounting seat, a second motor, and a fan gear fixed to one side of the mounting seat, the second rotating shaft is pivotally connected to the bracket through a bearing seat, and the output shaft of the second motor is provided with a third gear, and the third gear is meshed with the fan gear. The utility model realizes multi-angle steering of the workpiece, but in the utility model, the transmission is carried out through the fan gear, and the fan gear is large in size. During use, the staff may be accidentally scratched by the gear, and at the same time, a large amount of welding slag will be generated during the welding process, and the welding slag will fall to the meshing position of the third gear and the fan gear, affecting the normal transmission work.
