Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and in particular relates to a welding machine head. Background Art

[0002] The welding gun of a welding machine is generally fixed on the machine head, which is connected to the welding arm (welding robot arm) of the welding machine and moves with the movement of the welding arm. The machine head cannot adjust the position of the welding gun autonomously. In the actual welding process, the position of the welding gun (such as the height of the welding gun) needs to be constantly adjusted for different shapes and welding parts of the components to be welded. The existing machine head with a fixed welding gun cannot meet the requirements for welding accuracy, and cannot even complete all welding, which reduces the welding efficiency and also affects the welding quality. Therefore, a welding machine head is needed to solve the above technical problems. Utility Model Content

Clamping piece 1 and clamping piece 2 clamp the welding gun, and motor 1 is a forward and reverse motor. When motor 1 rotates forward, the two driving wheels rotate to move the welding gun downward, and when motor 1 rotates reversely, the two driving wheels rotate to move the welding gun upward. This setting can move the welding gun up and down, and reasonably adjust the height of the welding point of the welding gun according to needs to improve the welding effect.

[0030] Working principle: The welding gun is clamped and fixed on the mounting plate one by the clamping piece one and the clamping piece two. The forward and reverse rotation of the motor two can make the welding gun reciprocate along the direction of the rack to realize the horizontal movement of the welding gun.
