The parts welding tool according to claim 1, characterized in that: The distance adjustment mechanism comprises: Base; A threaded rod is rotatably arranged on the base, and the threaded rod is provided with two sections of external threads with opposite thread directions, and the bottom ends of the two support mechanisms are respectively threadedly connected to the two sections of external threads, so as to convert the rotation of the threaded rod into the movement of the two support mechanisms toward or away from each other along the length direction of the threaded rod; The distance adjustment driving member has a power output end connected to the threaded rod and is used to drive the threaded rod to rotate, so as to drive the two supporting mechanisms to move toward or away from each other along the length direction of the threaded rod.

3. The parts welding tool according to claim 2, characterized in that: The bottom ends of the two support mechanisms are both provided with threaded through holes.

4. The parts welding tool according to any one of claims 1 to 3, characterized in that: The rotating clamping mechanism comprises: A rotating ring plate is rotatably arranged on the top of the supporting mechanism; A first clamping block, arranged on the inner side of the rotating ring plate; A telescopic adjustment piece is arranged on one side of the first clamping block along the radial direction of the rotating ring plate inside the rotating ring plate, and a second clamping block is provided at the end of the telescopic adjustment piece facing the first clamping block, and the second clamping block is arranged opposite to the first clamping block. The second clamping block is used to move toward or away from the first clamping block along the radial direction of the rotating ring plate under the action of the telescopic adjustment piece to clamp or unlock the welded part.

5. The parts welding tool according to claim 4, characterized in that: Two limit blocks are provided on the wall surface of the first clamping block facing the second clamping block, and at least one of the limit blocks is connected to the first clamping block in a position-adjustable manner along the length direction of the first clamping block, and is used to adjust the distance between the two limit blocks to clamp parts to be welded of different widths.

6. The parts welding tool according to claim 5, characterized in that: At least two groups of fixing holes are provided on the wall surface of the first clamping block facing the second clamping block. The at least two groups of fixing holes are arranged at intervals along the length direction of the first clamping block. The limit block can be installed at any group of the fixing holes in a detachable manner.

7. The parts welding tool according to any one of claims 1 to 3, characterized in that: The rotating clamping mechanism is connected to a flipping driving mechanism for driving the rotating clamping mechanism to rotate.

8. The parts welding tool according to claim 7, characterized in that: The flipping driving mechanism comprises: Flip motor; The main wheel gear is connected to the power output end of the flip motor, and the rotating clamping mechanism is provided with a driven gear along its circumference, which is meshed with the main wheel gear.

9. The parts welding tool according to any one of claims 1 to 3, characterized in that: The support mechanism is a height adjustment structure, which includes: Fixed block; The movable block is arranged at the top of the fixed block in an adjustable manner along the height direction of the fixed block, and is used to adjust the height position, thereby adjusting the height position of the rotating clamping mechanism.

10. The parts welding tool according to any one of claims 1 to 3, characterized in that: A fixed ring frame is provided at the top of the supporting mechanism for supporting the rotating clamping mechanism.
