7. The multi-directional positioning metal welding equipment according to claim 6, characterized in that: Circular holes five are provided on both sides of the two guide rails (401), and the insides of the two opposite circular holes five are connected to the same adjusting screw rod (402) through bearings. Two screw motors (403) are provided on one side of the welding tool frame (1), and the driving end of the screw motor (403) and one end of the adjusting screw rod (402) are fixedly connected to pulleys, and the external transmission of the two pulleys is connected to the same belt (404).

8. The multi-directional positioning metal welding equipment according to claim 7, characterized in that: The upper side of the welding workbench (2) is fixedly connected to a limit seat (5), and one side of each of the two limit seats (5) is provided with two smooth holes, and the interiors of the plurality of smooth holes are slidably connected to a guide cylinder three (7).

9. The multi-directional positioning metal welding equipment according to claim 8, characterized in that: One end of the two guide cylinders three (7) located on the same side is fixedly connected to the same positioning slide (8), one side of the two limit seats (5) is fixedly connected to an electric drive rod four (9), and the driving end of the electric drive rod four (9) is fixedly connected to one side of the positioning slide (8).

10. A method for using a multi-directional positioning type metal piece welding device, using the multi-directional positioning type metal piece welding device according to claim 9, characterized in that: The steps include: Step 1: When positioning and welding the metal body (6), first place the metal body (6) on the welding workbench (2), and then start the screw motor (403), which drives the adjusting screw (402) to move the clamping plate (413) on the screw nut slide (405) to the side of the metal body (6) to be positioned; Step 2: Then start the electric drive rod 1 (407), and drive the horizontal moving plate (409) to move toward the side of the metal component body (6) through the electric drive rod 1 (407), and the two horizontal moving plates (409) move in opposite directions to initially clamp and position the two sides of the outside of the metal component body (6) through the clamping plate (413); Step 3, then start the electric telescopic rod (414), so that the positioning roller (437) on the lifting slide plate (415) moves to one side of the metal body (6), and according to the size of the welding angle of the metal body (6), adjust the angle of the angle adjustment track (418) by adjusting the motor 1 (417), and adjust the angle of the clamping tool frame (425) by adjusting the motor 2 (423). During the adjustment process, the angle positioner (426) is used to determine that the clamping tool frame (425) is located at the center of the welding angle; Step 4: After the adjustment is completed, the electric drive rod 2 (420) is started to drive the adjustment slider (419) to move the clamping tool frame (425) toward the welding angle, and the electric drive rod 3 (429) is started to drive the two-way gear rod (428) to move. The two-way gear rod (428) drives the linkage gear (432) to rotate so that the opening and closing support rod (431) opens until the positioning roller (437) contacts the positioning surface of the metal part body (6), so that the multiple positioning rollers (437) on the horizontal support seat (434) clamp and position the multiple sides of the inside of the metal part body (6).
