Detailed Implementation

[0013] The present invention will now be described in more detail with reference to the accompanying drawings. It should be noted that the description of the present invention with reference to the accompanying drawings is merely illustrative and not restrictive. Various embodiments can be combined with each other to form other embodiments not shown in the following description.

[0014] Please see Figures 1 to 5The pipe rotating device provided by this utility model includes a first rotating component 1, a second rotating component 2, a clamping component 3, a base 5, a base 6, and a bearing component 7.

[0015] Specifically, the first rotating assembly 1 includes a first motor 11 and a rotating plate 12. The rotating plate 12 includes a connecting part 121 and a meshing part 122 fixedly disposed on the connecting part 121. The first motor 11 meshes with the meshing part 122. The second rotating assembly 2 is fixedly disposed on one side of the connecting part 121. The clamping member 3 is rotatably disposed on the other side of the connecting part 121, and the second rotating assembly 2 meshes with the clamping member 3. The first motor 11 drives the pipe 4 to rotate in a first direction, and the second rotating assembly 2 drives the pipe 4 to rotate in a second direction.

[0016] The pipe rotation device provided in this embodiment has a clamping member 3 that can clamp a pipe 4. A first motor 11 can drive the rotating plate 12, the clamping member 3, and the pipe 4 to rotate in a first direction by engaging with the meshing part 122. A second rotation assembly 2 can drive the clamping member 3 and the pipe 4 to rotate in a second direction, thereby realizing the rotation of the pipe 4 in two directions.

[0017] To improve the accuracy of the pipe 4 rotating in the first direction, a gearbox can be added between the first motor 11 and the meshing part 122. The first motor 11 drives the meshing part 122 to rotate through the gearbox, thereby improving the accuracy of the pipe 4 rotating in the first direction.

[0018] The second rotating assembly 2 and the clamping member 3 are respectively fixedly disposed on the two sides of the connecting part 121. The clamping member 3 is rotatably connected to the connecting part 121. The second rotating assembly 2 can be a motor or a combination of a motor and gears. Therefore, the second rotating assembly 2 can control the angle of rotation of the clamping member 3 in the second direction. The clamping member 3 can be a three-jaw chuck, etc., which will not be described in detail here.

[0019] The engaging part 122 and the second rotating component 2 are disposed on the same side of the connecting part 121, and there are two engaging parts 122, which are arranged in parallel at intervals.

[0020] The base 5 is elongated, and the base 6 is fixedly installed on the base 5. The first motor 11 is fixedly installed on the base 6. The rotating plate 12 is rotatably connected to the base 6.

[0021] Please see Figures 3 to 4 The connecting part 121 has a rotating shaft protruding from both sides along its length, and the rotating shaft can rotate with the base 6. Therefore, the first direction refers to the direction of rotation around the rotating shaft, and the second direction refers to the direction of rotation of the pipe 4 along the central axis. The first direction is perpendicular to the second direction.

[0022] The load-bearing assembly 7 includes a fixed base 71, a telescopic column 72, a load-bearing base 73, and a load-bearing wheel 74. The fixed base 71 is fixedly installed on the base 5. The load-bearing base 73 is located on the upper side of the fixed base 71. One end of the telescopic column 72 is connected to the fixed base 71, and the other end is connected to the load-bearing base 73. The load-bearing wheel 74 is rotatably installed on the load-bearing base 73, and the load-bearing wheel 74 abuts against the pipe 4.

[0023] The bearing wheel 74 can support the pipe 4. In addition, the telescopic column 72 can change its length, thereby changing the height of the bearing seat 73 and the bearing wheel 74, so that the bearing wheel 74 can support pipes 4 of different diameters.

[0024] The support assembly 7 also includes a plurality of support plates 75 fixedly mounted on the support base 73. The support plates 75 are provided with support grooves 751 extending in the vertical direction. The support wheel 74 is provided with a rotating shaft 741 protruding out and inserted into the support groove 751.

[0025] The support assembly 7 also includes an elastic element 76 disposed in the support groove 751, and the rotating shaft 741 abuts against the elastic element 76.

[0026] Two shafts 741 are provided, and they are symmetrically arranged on two sides of the bearing wheel 74 along the axis.

[0027] It should be clear that the pipe rotating device provided in this embodiment needs to work in conjunction with an external welding device. This welding device can weld on the lower inner wall of the pipe 4 in a horizontal straight direction, that is, weld a straight weld seam that extends axially on the lower inner wall of the pipe 4, thereby improving the wear resistance of the pipe 4.

[0028] When the pipe 4 held by the clamping member 3 is a cylindrical pipe, since the diameter of the cylindrical pipe is the same everywhere, the cylindrical pipe does not need to be rotated in the first direction and can remain horizontal. At this time, the external welding device can directly weld the lower inner wall of the cylindrical pipe. After a weld is completed, the second rotating component 2 drives the cylindrical pipe to rotate in the second direction at a certain angle, and the external welding device can continue to weld the lower inner wall of the cylindrical pipe.

[0029] When the clamping element 3 clamps a tapered pipe 4, because the tapered pipe has a taper, such as Figure 4 As shown in the left figure, although the central axis of the conical pipe remains horizontal, the lower inner wall of the conical pipe forms an angle with the horizontal direction. Therefore, it is necessary to first rotate the conical pipe a certain angle along the first direction using the first rotating assembly 1. Figure 4As shown in the right figure, the lower inner wall of the tapered pipe is kept horizontal so that the external welding device can weld the lower inner wall of the tapered pipe. After one weld is completed, the tapered pipe is rotated at a certain angle in the second direction by the second rotating component 2, and the external welding device can continue to weld the lower inner wall of the tapered pipe.

[0030] Very importantly, when the tapered pipe is in Figure 4 In the state shown in the left-middle diagram, the contact area between the tapered pipe and the bearing wheel 74 is small, which leads to poor stability of the tapered pipe and may even cause indentations at the contact point, thus affecting the quality of the tapered pipe. To avoid this, this embodiment provides an elastic element 76 in the bearing groove 751. The elastic element 76 can be a spring, leaf spring, etc. When the tapered pipe presses on the bearing wheel 74, the side of the bearing wheel 74 with greater pressure will squeeze the elastic element 76 and tilt downwards, while the side of the bearing wheel 74 with less pressure will tilt upwards. This increases the contact area between the bearing wheel 74 and the tapered pipe, thereby increasing the stability of the tapered pipe and preventing indentations. Furthermore, when the first rotating component 1 drives the tapered pipe to rotate in the first direction, that is, when the tapered pipe rotates along the first direction... Figure 4 As the tapered pipe moves from the left to the right, its lower side gradually approaches a horizontal state. Consequently, the pressure of the tapered pipe on the bearing wheel 74 gradually becomes more uniform. Therefore, under the action of the elastic element 76, the bearing wheel 74 also gradually approaches a horizontal state until the lower side of the tapered pipe reaches a horizontal state.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
