DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] To solve the technical problem of how to adjust the concentricity when metal pipes are butt-jointed, please refer to Figure 1-Figure 4 , this embodiment provides the following technical solutions:

[0022] A metal pipe docking adjustment device comprises a base 1 and an adjustment mechanism 2, wherein the adjustment mechanism 2 comprises a docking plate 21, and an adjustment roller 23 is movably provided at the side end of the docking plate 21, wherein there are three adjustment rollers 23 and the adjustment rollers 23 are movably arranged in an angular distribution, and a pipe body 3 is movably sleeved outside the adjustment rollers 23, and the length of the adjustment rollers 23 is less than the length of the pipe body 3.

[0023] The interior of the docking plate 21 is hollow and a rotating shaft 25 is movably installed thereon. One end of the rotating shaft 25 is fixedly connected to the second motor 22. A first bevel gear 26 is fixedly sleeved on the rotating shaft 25. A threaded rod 28 is also movably installed therein. There are three threaded rods 28 and they are distributed in a ring array about the rotating shaft 25. One end of the threaded rod 28 is fixedly connected to the second bevel gear 27, which is meshingly connected to the first bevel gear 26.

[0024] A threaded sleeve 29 is threadedly connected to the threaded rod 28 , and the threaded sleeve 29 is fixedly connected to the adjusting roller 23 . A second sliding groove 24 is provided on the docking plate 21 , and the adjusting roller 23 and the second sliding groove 24 form a sliding connection.

[0025] It should be noted that, in the initial state, the distances between the three adjusting rollers 23 and the rotating shaft 25 are the same, and the three threaded rods 28 , the three threaded sleeves 29 , the three second bevel gears 27 and the three adjusting rollers 23 are all of the same size.

[0026] Specifically, the two tube bodies 3 are sleeved outside the corresponding left and right adjusting rollers 23, and the two second motors 22 are started. The second motors 22 drive the rotating shaft 25 to rotate, and the rotating shaft 25 then drives the first bevel gear 26 fixed thereto to rotate, and the first bevel gear 26 then drives the three second bevel gears 27 meshing therewith to rotate at the same speed, and the second bevel gear 27 then drives the three threaded rods 28 fixed thereto to rotate at the same speed, so that the three threaded sleeves 29 can drive the three adjusting rollers 23 to move the same distance until the outer wall of the adjusting roller 23 is tightly fitted with the inner wall of the tube body 3. At this time, the tube body 3 is supported and fixed, and its center is located on a horizontal line with the center of the rotating shaft 25, and the centers of the left and right rotating shafts 25 are located on a straight line, so that the centers of the left and right tube bodies 3 are located on a straight line, thereby realizing the adjustment of the concentricity of the ends of the tube body 3.

[0027] Among them, the adjusting roller 23 is set in an angular shape, which utilizes the principle of high stability of a triangle to improve the stability of supporting and fixing the tube body 3. The length of the adjusting roller 23 is smaller than the length of the tube body 3 in order to make the end of the tube body 3 protrude for easy welding. The second slide groove 24 is set to limit the movement of the adjusting roller 23 so that the adjusting roller 23 can stably move in translation.

[0028] To solve the technical problem of how to butt metal pipes, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0029] A bidirectional screw rod 11 is movably installed in the base 1, one end of the bidirectional screw rod 11 is fixedly connected to a first motor 12, a movable seat 14 is symmetrically threaded on the bidirectional screw rod 11, a docking plate 21 is fixedly connected to the movable seat 14 by bolts, and a first slide groove 13 is symmetrically opened on the upper surface of the base 1, and the movable seat 14 and the first slide groove 13 form a sliding connection.

[0030] Specifically, when the positions of the two tube bodies 3 are adjusted, the first motor 12 is started, and the first motor 12 drives the bidirectional screw rod 11 to rotate. Under the limitation of the first slide groove 13, the two movable seats 14 can stably translate toward each other, driving the docking plates 21 fixedly connected thereto to translate toward each other until the ends of the two tube bodies 3 are docked.

[0031] Working principle: When the metal pipe docking adjustment device is used, the two pipe bodies 3 are respectively placed on the left and right docking plates 21, and the two second motors 22 are started. The second motors 22 drive the left and right rotating shafts 25 to rotate at the same speed, and the rotating shafts 25 then drive the two first bevel gears 26 fixed thereto to rotate at the same speed. The first bevel gears 26 drive the three second bevel gears 27 meshing therewith to rotate at the same speed, and the second bevel gears 27 then drive the three threaded rods 28 fixed thereto to rotate at the same speed, so that the threaded sleeves 22 threadedly connected to the threaded rods 28 are 9 can move outward by the same distance, thereby driving the three adjusting rollers 23 to move outward by the same distance, until the outer wall of the adjusting roller 23 is tightly fitted with the inner wall of the tube body 3, supporting and fixing the tube body 3. At this time, the centers of the left and right tube bodies 3 are aligned with the center of the rotating shaft 25, and are located on a horizontal line with the center of the rotating shaft 25, so as to achieve concentricity adjustment. Then, the first motor 12 is started, and the first motor 12 drives the bidirectional screw rod 11 to rotate. Under the limit of the first slide groove 13, the two docking plates 21 move toward each other until the ends of the tube body 3 are docked.
