DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example:

[0021] This embodiment discloses a steel pipe welding position correction device, see Figures 1 to 3 , including a workbench 1 and a correction mechanism 2, wherein the correction mechanism 2 is arranged on the surface of the workbench 1.

[0022] Specifically, Figure 1 , Figure 2As shown, the correction mechanism 2 includes two symmetrically arranged L-shaped clamps 201 and a worm 202; the bottom of one end of the two L-shaped clamps 201 on the opposite side is fixedly connected to a rotating shaft 203, the bottom end of the rotating shaft 203 is rotatably connected to the workbench 1 through a mounting bearing, a worm wheel 204 is fixedly connected to the surface of the rotating shaft 203, both ends of the worm 202 are rotatably connected to the workbench 1 through a supporting seat, and the two sides of the worm 202 are respectively meshed with the opposite sides of the two worm wheels 204, a pressing plate 205 is provided on the top surface of one end of the L-shaped clamp 201, and a mounting seat 206 is fixedly connected to the end of the L-shaped clamp 201, and a bolt 207 is threadedly connected to the mounting seat 206. The bolt 207 is The end is rotatably connected to the surface of one side of the pressure plate 205, and the other side of the L-shaped clamping plate 201 is slidably connected to the workbench 1. One end of the worm 202 extends to the outside of one side of the workbench 1 and is fixedly connected to a handwheel 208. The two steel pipes to be welded are respectively placed on the surfaces of the two L-shaped clamping plates 201, and the bolt 207 is turned. The bolt 207 spirally moves forward or backward on the mounting seat 206 to drive the pressure plate 205 to clamp and fix the steel pipe and the L-shaped clamping plate 201. The worm 202 is rotated by the handwheel 208. The worm 202 drives the two L-shaped clamping plates 201 to rotate in the opposite or reverse direction around the two rotating shafts 203 through the worm wheel 204 and the rotating shaft 203, thereby adjusting the welding angle of the two steel pipes.

[0023] Further, such as Figure 1 , Figure 2 As shown, a rectangular block 2011 is provided at one end of the two L-shaped clamps 201 on one side opposite to each other, and a cavity is formed along the two blocks 2011 on the two L-shaped clamps 201 on one side opposite to each other. When two steel pipes are butt-welded, the two rectangular blocks 2011 are connected. At this time, a cavity is formed along the two blocks 2011 on the two sides opposite to each other of the L-shaped clamps 201, so that the surfaces of the welding ends of the two steel pipes can be exposed, which is convenient for welding the welding ends.

[0024] Furthermore, if Figure 3 As shown, one end of the bolt 207 has a smooth surface, and the smooth end of the bolt 207 is fixedly connected to the limiting ring 2071. A mounting hole 2051 is provided on the side opposite to the bolt 207 of the pressure plate 205. A circular limiting hole 2052 is provided on one side of the mounting hole 2051 to fit the limiting ring 2071. The diameter of the limiting ring 2071 is larger than the diameter of the mounting hole 2051. The rotation of the bolt 207 drives the smooth end of the bolt 207 to rotate in the mounting hole 2051, and at the same time drives the limiting ring 2071 to rotate in the limiting hole 2052. Since the diameter of the limiting ring 2071 is larger than the diameter of the mounting hole 2051, the bolt 207 can drive the pressure plate 205 forward or backward when it spirals forward or backward on the mounting seat 206.

[0025] It is worth noting that if Figure 1 , Figure 2As shown, a slide bar 2012 is fixedly connected to the bottom of the other side of the L-shaped splint 201, and a slide groove 101 with a circular arc shape and a rotating shaft 203 as the center is opened at a position of the workbench 1 relative to the slide bar 2012. The bottom end of the slide bar 2012 extends into the slide groove 101 and is slidably connected to the slide groove 101. When the L-shaped splint 201 rotates around the rotating shaft 203, the slide bar 2012 is driven to slide in the slide groove 101 around the rotating shaft 203 to support the L-shaped splint 201.

[0026] Working principle: The utility model places two steel pipes to be welded on the surfaces of two L-shaped clamps 201 respectively, rotates the bolt 207, and the bolt 207 spirally moves forward or backward on the mounting seat 206. The rotation of the bolt 207 drives the smooth end of the bolt 207 to rotate in the mounting hole 2051, and at the same time drives the limiting ring 2071 to rotate in the limiting hole 2052. Since the diameter of the limiting ring 2071 is larger than the diameter of the mounting hole 2051, the bolt 207 is on the mounting seat 206. The forward or backward movement of the spiral can drive the pressure plate 205 forward or backward to clamp the steel pipe and the L-shaped clamp 201. The worm 202 is rotated by the handwheel 208. The worm 202 drives the two L-shaped clamps 201 to rotate in the opposite or reverse directions around the two rotating shafts 203 through the worm wheel 204 and the rotating shaft 203, and drives the slide bar 2012 to slide in the slide groove 101 around the rotating shaft 203, so as to support the L-shaped clamp 201 and adjust the welding angle of the two steel pipes.
