Description

Technical Field

[0002] The horizontal and vertical beams of the shelf need to be welded using a welding gun. In order to meet various welding needs, different welding machines have gradually evolved.

Two slide rails are symmetrically provided on the front and rear sides of the top of the frame, and a sliding motor is slidably connected to the slide rails. The top of the sliding motor is provided with the mobile platform, which solves the problem that the welding between the beam and the hanging angle of the existing shelf is generally done by manual welding, resulting in high labor intensity.
