Compared to traditional processes, they offer significant advantages, including high production efficiency, superior welding quality, environmental friendliness, and energy savings. The use of automated welding machines requires the use of a robotic arm, which is typically transported by a cart.

[0003] The publication number CN214558495U was retrieved, which discloses a manipulator transporting device for an automated welding machine. The manipulator is fixed and clamped by adjusting the clamping assembly, and through multi-directional adjustment, manipulators of most specifications can be fixed, thereby increasing the applicability of the pushing device, so that manipulators of different sizes and specifications can be effectively fixed and clamped during transport, thereby preventing the manipulator from being bumped and damaged during transport.

The threads on both sides of the screw 13 rotate in opposite directions, and the screw 13 is threadedly connected to the slider 14. During the rotation of the screw 13, the two groups of sliders 14 can be driven to move relative to or in reverse in the slide groove 12, thereby driving the two groups of splints 11 to move relative to or in reverse on the upper surface of the mobile base 1.
