This invention relates to the field of
laser welding technology, specifically to a
laser welding device for
metal shelf
processing. The adjustment unit includes a protective shell fixedly mounted on a positioning plate, a sleeve rotatably mounted on the protective shell, a limit block fixedly mounted on the sleeve, and a control mechanism for controlling the angular offset of the shell on the limit block. A rotating worm gear drives the positioning shaft at its center to rotate, and then drives the rotating shaft to rotate through a
universal joint. The rotating shaft controls the horizontal movement of two racks while controlling the rotation of the gears, thereby controlling the horizontal movement of the clamping plates and achieving positioning and clamping of materials of different sizes. When the
servo reducers at the upper and lower
layers of the protective shell are rotated, the worm drives the worm wheel to rotate, and the rotating worm wheel can rotate the sleeve, thereby controlling the rotation of the limit block. This allows the
axial rotation of the shell to be controlled by the vertical plate, thus achieving axial angle adjustment of the materials.
