when the welding platform for production of the enclosure stand column is converted from an initial state to a working state, the driving motor drives the driving gear to rotate, so that the driven gear, the driving shaft and the special-shaped lifting gear are driven to rotate, and the driven gear rotates to drive the arc-shaped outer gear ring and the welding workbench to rotate; in the rotating process of the welding workbench, the inclined block is in contact with the lower end face of the special-shaped lifting gear, the inclined block drives the special-shaped lifting gear to move from one end of the driving shaft to the other end of the driving shaft, so that a first V-shaped tooth of the special-shaped lifting gear is meshed with a second V-shaped tooth on the special-shaped transition gear, and meanwhile, the pin shaft drives the poke rod to swing relative to the extension part towards the rotating direction of the welding workbench;
when the first V-shaped teeth and the second V-shaped teeth are meshed, the welding workbench rotates until a gap between adjacent arc-shaped outer gear rings is aligned with the driven gear, the driven gear is not meshed with the arc-shaped outer gear rings, and the welding workbench stops rotating; the first V-shaped teeth and the second V-shaped teeth are meshed, the special-shaped lifting gear drives the special-shaped transition gear and the reciprocating screw rod to rotate, the special-shaped lifting gear is lifted by the special-shaped transition gear along with the rotation of the special-shaped lifting gear, so that the special-shaped lifting gear is separated from the inclined block, when the slide block moves upwards relative to the reciprocating screw rod, the poke rod is separated from the pin shaft, and the poke rod automatically returns to an initial state position; when the sliding block moves downwards relative to the reciprocating screw rod, the poke rod is in contact with the pin shaft, and along with the fact that the poke rod continues to move downwards, the poke rod can poke the pin shaft and the inclined block to move towards the rotating direction of the welding workbench, so that the welding workbench is driven to rotate, and the driven gear is meshed with the arc-shaped outer gear ring;
when the welding platform for producing the enclosure upright post is converted from the working state to the initial state, the driving motor stops rotating, the driving gear, the driving shaft, the driven gear and the special-shaped lifting gear stop rotating, the special-shaped transition gear continues rotating under the inertia effect to enable the first V-shaped teeth and the second V-shaped teeth to be separated, and under the self-weight effect of the special-shaped lifting gear, the special-shaped lifting gear automatically moves from the other end of the driving shaft to one end and moves to the position where the lower end face of the special-shaped lifting gear is in contact with the transition plane on the driving shaft.
2. The welding platform for producing the enclosure stand column as claimed in claim 1, further comprising a support plate connected to the base, wherein the support plate is provided with a guide rail, and the slide block is provided with a sliding groove matched with the guide rail.
3. The welding platform for producing the enclosure stand column as claimed in claim 1, wherein the welding mechanism includes a rotating arm, a first rotary driving member, a second rotary driving member, and a welding gun, the first rotary driving member is mounted at the other end of the slider, the first rotary driving member is connected to one end of the rotating arm, the second rotary driving member is mounted at the other end of the rotating arm, and the welding gun is connected to the second rotary driving member.
4. The welding platform for producing the enclosure column as claimed in claim 3, wherein the first rotary driving member and the second rotary driving member are both motors.
