DETAILED DESCRIPTION

[0017] The following will be combined with the drawings Figs. 1-3 The application will be further described in detail.

[0018] The application embodiment discloses a welding tool, referring to Figs. 1-2 , including a connecting plate 6, the top surface of the connecting plate 6 is fixedly provided with two fixed plates 9, the opposite side of each of the two fixed plates 9 is fixedly provided with two guide rods 11, the outer wall of each of the two guide rods 11 is slidably sleeved with a moving plate 8, the moving plate 8 and the fixed plate 9 are both provided with a groove 12, the top surface of each of the moving plate 8 and the fixed plate 9 is threadedly provided with a threaded rod 14, the top surface of the threaded rod 14 is fixedly provided with a knob 13, the bottom surface of the threaded rod 14 is connected with an arc-shaped plate 15 through a bearing, by rotating the knob 13, the rotation of the knob 13 drives the threaded rod 14 and the arc-shaped plate 15 to move vertically downward, by adjusting the position of the four arc-shaped plates 15, different diameter steel pipes can be clamped and fixed, which is convenient for the splicing and girth welding between the steel pipes later.

[0019] Referring to Figs. 2-3The free ends of the two guide rods 11 are fixedly connected to side plates 10, which are fixedly set at both ends of the top surface of the connecting plate 6. The top surface of the connecting plate 6 is provided with sliding openings 16 at both ends. The bottom surfaces of the two movable plates 8 are fixedly provided with support rods 17, the bottom ends of the support rods 17 pass through the sliding openings 16, and extend downwards with threads fitted with nuts 18. The two movable plates 8 are moved along the horizontal direction of the guide rods 11 respectively. The movement of the movable plates 8 drives the support rods 17 to move inside the sliding openings 16. The positions of the two movable plates 8 can be adjusted according to the length of the two steel pipes. After the positions of the movable plates 8 are moved, the movable plates 8 and the connecting plate 6 can be fixedly connected by the support rods 17 and the nuts 18. The device has a simple structure and is easy to use. It is especially suitable for steel pipe welding in small factory riveting and welding workshops.
