[0027] Under the existing technical conditions, according to the design of the production process of the threaded pipe, it is often necessary to rotate the pipe body of the threaded pipe semi-finished product, and then cooperate with other process operations to complete the corresponding process requirements. However, the existing threaded pipe body rotation equipment usually has problems such as low reliability, high failure rate, and a single type of threaded pipe that it is suitable for.

[0028] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0029] In an embodiment of the present utility model, as Figures 1 to 5As shown in the figure, a tube body rotation device for the production of threaded tubes includes a base; on the upper surface of the base, there are a linear slide rail 1 and a rack 3 arranged in parallel; the slide 2 of the linear slide rail 1 is fixedly connected to a first drive motor 21 and a second drive motor 23; the output shaft of the first drive motor 21 is coaxially fixedly connected to a gear 22, and the gear 22 meshes with the rack 3; the output shaft of the second drive motor 23 is coaxially fixedly connected to one end of a cylindrical tube plug 25, the other end of the tube plug 25 is coaxially fixedly connected to one end of a cylindrical first connecting portion 26, and the other end of the first connecting portion 26 is coaxially fixedly connected to one end of a cylindrical second connecting portion 27; the diameter of the first connecting portion 26 is larger than that of the second connecting portion 27; the outer surface of the first connecting portion 26 is provided with an anti-slip rubber layer for contacting the inner wall of the threaded tube, and the outer surface of the second connecting portion 27 is provided with threads for connecting with the inner wall of the threaded tube; the axis of the tube plug 25 is parallel to the linear slide rail 1.

[0030] In this embodiment, first, the operator fixes one end of the threaded tube on the tube plug 25. If it is an internal threaded tube, there are threads on the inner wall of the threaded tube, so the internal threaded tube can be threadedly connected to the second connecting portion 27, and further, the internal threaded tube can be rotated. If it is an external threaded tube, the threads are arranged on the outer wall of the threaded tube, so the external threaded tube is fixed by contacting the anti-slip rubber layer on the outer surface of the first connecting portion 26, and further, the external threaded tube can be rotated. Therefore, this device can be suitable for two types of threaded tubes to realize the stable rotation of the tube body 7.

[0031] In this embodiment, after the tube plug 25 fixes the threaded tube, the second drive motor 23 drives the tube plug 25 to rotate, and further, the tube plug 25 drives the connected threaded tube to rotate.

[0032] In this embodiment, the first drive motor 21 drives the gear 22 to crawl on the rack 3. Since the first drive motor 21 is fixedly connected to the slide 2, the gear 22 drives the slide 2 to move on the linear slide rail 1, thereby realizing the axial stable movement of the threaded tube connected to the tube plug 25.

[0033] In this embodiment, the first drive motor 21 is connected to a first motor controller 4, and the second drive motor 23 is connected to a second motor controller 5.

[0034] In this embodiment, the first motor controller 4 and the second motor controller 5 respectively control the rotation speeds of the first drive motor 21 and the second drive motor 23, and further control the rotation speed of the tube body 7 and the axial movement speed of the tube body 7, so that the state of the tube body 7 adapts to the process requirements in production.

[0035] In another embodiment of the present utility model, as Figure 2 shown, both the first motor controller 4 and the second motor controller 5 are arranged on the upper surface of the base.

[0036] In another embodiment of the present utility model, as Figure 3 shown, a vertically arranged fixed plate 24 is provided on the sliding table 2, and a pedestal bearing 28 is provided on the fixed plate 24. The output shaft of the second driving motor 23 passes through the pedestal bearing 28 and is connected to the pipe plug 25.

[0038] In another embodiment of the present utility model, as Figure 4 shown, a fixed seat 6 is provided on the side wall of the outer surface of the base.

[0039] In this embodiment, the setting of the fixed seat 6 is used to fix the base.

[0040] In this embodiment, the fixed seat 6 is provided with a through hole.

[0041] In this embodiment, both the first driving motor 21 and the second driving motor 23 are servo motors.

[0042] In this embodiment, the servo motor can precisely control the rotation speed of the pipe body 7 and the axial movement speed.

[0043] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, the threaded connection of the second connection portion 27 of the pipe plug 25 with the pipe body 7 of the internal threaded pipe realizes the connection to the internal threaded pipe and rotates the pipe body 7.

[0044] In an embodiment of the present utility model, as Figure 3 and Figure 5 shown, the anti-slip rubber layer of the first connection portion 26 of the pipe plug 25 frictionally fixes the pipe body 7 of the external threaded pipe, realizes the connection to the external threaded pipe, and rotates the pipe body 7.

[0045] The settings of the first connection portion 26 and the second connection portion 27 on the pipe plug 25 can respectively be suitable for two different types of threaded pipes.
