Description

Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to a multi-directional adjustable welding robot. Background Art

[0006] Preferably, the electric telescopic rod is fixedly welded to the inner wall of the mounting frame, and the two electric telescopic rods are symmetrically arranged on the same diameter of the semicircular mounting frame.

[0007] Preferably, the motor is fixed to one side of the connecting seat, the output shaft of the motor passes through the connecting seat and extends to the other side of the connecting seat, the output shaft of the motor and the end of the rotating shaft are fixed with connecting flanges, and the two connecting flanges are fixed by bolts.

[0008] Preferably, a mounting seat is fixed on the top of the base, the top of which is connected to elbow joint 1, and the top of elbow joint 1 is rotatably connected to arm rod 1, the top of arm rod 1 is connected to elbow joint 2, and arm rod 2 is rotatably mounted on the top of elbow joint 2, a connecting seat is fixed on the front end of arm rod 2, elbow joint 1 and elbow joint 2 are both driven by a motor, and the axis of the middle part of elbow joint 1 and elbow joint 2 is connected to the motor through a reducer. Beneficial Effects

[0009] The utility model provides a multi-directional adjustable welding robot. It has the following beneficial effects:

[0010] The multi-directionally adjustable welding robot drives the rotating shaft to rotate through a motor, which drives the gear to rotate. When the gear rotates, the connecting seat is engaged with the gear through the tooth groove, so when the gear rotates, it drives the connecting seat to rotate around its center of circle. The two welding guns work at the same time. When the connecting seat rotates half a circle, the welding of the tubular part is completed. The multi-directionally adjustable welding robot can control the welding gun to rotate around the tubular welding part and automatically complete the welding of the tubular welding part, which can greatly improve work efficiency and is extremely convenient to use.
