Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and particularly relates to a welding torch swing device. Background Art

[0002] Corner swing is a swing mode of the welding torch during welding. Generally, in a corner swing device, the welding torch is fixed to a swing shaft, and the swing shaft drives the welding torch to perform a corner swing movement. The problems brought by this swing device are as follows: if the reduction ratio of the speed reducer is too small, due to the drag of the welding cable, the self-locking property of the welding torch position will be too poor; if the reduction ratio is large, the swing speed will be too slow to keep up with the advancing pace of the welding torch, resulting in the disconnection of the molten pool; in addition, the clearance of the speed reducer or the swing shaft is further enlarged at the end of the welding torch, and the welding stability becomes poor. Summary of the Invention

[0003] To solve the above technical problems, a technical solution adopted by the utility model is:

[0011] Further, the driving element is also connected to a gear reduction box.

[0012] Advantages of the present utility model:

[0013] 1. When the driving element is used to drive the gear element to rotate in the present utility model, and then drive the welding torch on the swing seat to rotate on the frame body, the vertical position of the welding torch can be adjusted without interference, achieving a smaller swing radius and a larger rotation angle.

[0014] 2. When the gap of the system of the present utility model is transmitted to the end of the welding torch, the corresponding jitter distance is instead reduced by several times, strengthening the stability of the welding torch. Description of the drawings
