The reversing assembly is arranged between the arc-shaped frame 13 and the electric sliding rail 15. The arrangement of the reversing assembly enables the relevant structure arranged on the electric sliding rail 15 to be integrally rotated to the other side of the arc-shaped frame 13 when needed. This is the purpose of the open arrangement of the lower end of the arc-shaped frame 13, which is used to meet the needs of the rotation of this part. It should be noted that the rotating shaft 12 drives the arc-shaped frame 13 to rotate, and the rotating track is on the same circular arc as the arc-shaped part of the elbow tee joint 3 in the figure. The reversing assembly comprises a rotating motor 14 and a shaft body. The rotating motor 14 is fixedly installed on the arc-shaped frame 13. The shaft body is fixedly installed on the driving end of the rotating motor 14, and the lower end of the shaft body is fixedly connected with the electric sliding rail 15. An electric motor base is fixedly installed on the arc-shaped frame 13, and the rotating motor 14 is fixedly installed on the electric motor base. Bearings matched with the driving end of the rotating motor 14 are arranged on the electric motor base and the arc-shaped frame 13.

[0044] With reference toFigures 1-11 A movable frame 16 is mounted on the electric slide rail 15. The electric slide rail 15 is also existing technology and can control the movement of the movable frame 16 on it. The electric slide rail 15 shown in the figure is ring-shaped and is used to cooperate with the cutting kerf of the elbow tee 3. One end of the movable frame 16 is threaded with a mounting rod 17. The threaded setting here can adjust the clamping between the plasma cutting gun 18 and the elbow tee 3 to a certain extent. Furthermore, the thread here can be replaced by other structures, so that the clamping between the plasma cutting gun 18 and the elbow tee 3 can be adjusted at multiple angles. At this time, one end of the movable frame 16 can be set as a ball, and then the part of the mounting rod 17 that cooperates with it can be set as an arc shape to facilitate the relative rotation of the two. At this time, a fixing structure can also be set between the two to ensure locking and fixing after rotation. The plasma cutting gun 18 is fixedly mounted on one end of the mounting rod 17. Plasma cutting is an existing high-energy-density cutting process and a mature technology. It also includes control systems, etc., which will not be described in detail here.

[0045] An electric slide rail 15 is equipped with a pipe-end clamping component, which clamps the port of the elbow tee 3 and internally clamps the inner wall of the port. The pipe-end clamping component includes a support frame 19, a telescopic assembly, a clamping plate 21, and an internal clamping assembly. The support frame 19 is fixedly installed on the electric slide rail 15. A clamping plate 21 is installed on one side of the support frame 19 via a telescopic assembly. The telescopic assembly includes an electric telescopic rod 20. An electric telescopic rod 20 is fixedly installed on one side of the support frame 19, and one end of the electric telescopic rod 20 is fixedly set to the clamping plate 21. The clamping plate 21 is annularly arranged, and an internal clamping assembly is installed on the clamping plate 21. The internal clamping assembly includes a screw 22, a gear 23, a gear ring 24, and a clamping frame 25. The clamping plate 21 rotates... A screw 22 is mounted on the device, and a gear 23 is fixedly mounted on the screw 22. A gear ring 24 is slidably mounted on one side of the clamping plate 21 with limiting damping, and the gear ring 24 meshes with the gear 23. The screw 22 has a thread, and a clamping frame 25 is threaded onto the thread. A protrusion is fixedly mounted on the clamping frame 25. A strip groove that mates with the protrusion is opened on the side of the clamping plate 21 away from the gear ring 24. The engagement of the protrusion and the strip groove ensures that the clamping frame 25 can only move relative to the clamping plate 21 and will not rotate, thus ensuring that the clamping frame 25 can only move along the length of the screw 22. An elastic pad can also be provided on the outer wall of the clamping frame 25 to avoid direct contact. The clamping frame 25 can be configured as two or more as needed.

[0046] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0047] The specific use method of the present application is as follows:

[0048] Step one: first make the compression seat 5 in the highest position, then put the elbow tee 3 into it, then release the force applied to the compression seat 5 to make it move down and contact with the elbow tee 3, then press the compression knob 6 to compress the compression seat 5, and at the same time, apply a rotating force to the tooth ring one 10, which can drive the two gear one 9 to rotate at the same time, and the gear one 9 rotating drives the abutting block 8 to move and abuts the upper part of the elbow tee 3. In the specific use process, the rotating compression between the tooth ring one 10 and the compression knob 6 can be adjusted appropriately according to the needs.

[0049] Step two: start the servo motor 11, which works through the rotating shaft 12 and the arc-shaped frame 13 to drive the plasma cutting gun 18 to rotate to the appropriate position, at which the plasma cutting gun 18 is located at the cutting position, and at this time the electric sliding rail 15 and the port of the elbow tee 3 close to one end are flush; then start the electric telescopic rod 20, which works to drive the abutting disc 21 to abut the port of the elbow tee 3, at this time the tooth ring two 24 can also be rotated, which drives the screw rod two 22 to rotate through the gear two 23, and then makes the two abutting frames 25 move away from each other, and in the initial state the two abutting frames 25 are in the closest state, and the abutting frames 25 are used to further fix the inner wall of the port of the elbow tee 3 by moving away from each other.

[0050] Step three: start the electric sliding rail 15, which can drive the plasma cutting gun 18 to rotate around the axis, and then complete the cutting operation.

[0051] Step four: if the other end of the elbow tee 3 needs to be cut, first reset the electric telescopic rod 20 and the abutting frame 25, then start the rotating motor 14, which works to drive the electric sliding rail 15, the plasma cutting gun 18 and the abutting disc 21 to rotate together, and the whole rotates 180°. It should be noted that when the abutting disc 21 and the support frame 19 are at the shortest distance, the size of this part is smaller than the radius length of the electric sliding rail 15, which ensures the normal rotation.

[0052] The inner wall of the arc-shaped frame 13 and the outer wall of the electric sliding rail 15 are both arc-shaped, and both are provided with elastic pads to ensure the supporting effect during use and reduce wear under the premise of meeting the normal rotation requirements.

[0053] Step five: reverse rotate the arc-shaped frame 13 to the other end of the elbow tee 3 through the servo motor 11, and then repeat the above operation.

[0054] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
