[0016] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0017] As Figures 1-8 shown, a stainless steel pipe joint welding device based on a horizontal CNC machine tool includes a machine tool body 1. Inside the machine tool body 1, a support plate 2 is fixedly installed. Above the support plate 2, a vertical plate 3 is fixedly installed. On one side of the vertical plate 3, two groups of clamps 4 are provided. Below the two groups of clamps 4, bending members 14 are provided. The clamps 4 are connected to the bending members 14 through a driving mechanism. Inside the two bending members 14, a rotating shaft 15 is rotatably installed. The rotating shaft 15 is fixedly connected to the vertical plate 3. On the adjacent side of the two groups of clamps 4, a supporting mechanism is provided. Between the bending member 14 and the vertical plate 3, a limiting mechanism is provided. On the side of the bending member 14 close to the clamp 4, a supporting plate 35 is provided. Between the supporting plate 35 and the bending member 14, an elastic member 34 is installed. Inside the machine tool body 1, a cutting member 5 is fixedly installed. Above the inside of the machine tool body 1, a fixing frame 6 is fixedly installed. Below the fixing frame 6, a welding member 7 is slidably installed.

[0018] Specifically, the pipe fitting to be processed is placed above the supporting plate 35. The driving mechanism drives the two groups of clamps 4 to approach each other. The clamps 4 clamp the pipe fitting from both ends. Under the action of the supporting mechanism, the pipe fitting can be limited from the outside, increasing the stability of the pipe fitting. At this time, the cutting member 5 cuts the pipe fitting. After cutting is completed, the two bending members 14 rotate around the rotating shaft 15, so as to drive the pipe fitting to bend. Under the action of the fixing frame 6, the welding member 7 welds the bent fixing frame 6.

[0019] The driving mechanism includes two groups of adjusting plates 11. The two groups of adjusting plates 11 are respectively located on the sides of the two groups of clamps 4 away from each other. The adjusting plate 11 is connected to the bending member 14 through a sliding component. Between the adjusting plate 11 and the clamp 4, a first spring 13 is installed.

[0020] The sliding component includes a chute 16 and a slider 17. The chute 16 is opened inside the bending member 14. The slider 17 is slidably installed inside the chute 16. The slider 17 is fixedly connected to the adjusting plate 11. Between the two sliders 17, a moving mechanism is provided.

[0021] Specifically, the moving mechanism drives the two sliders 17 to approach or move away from each other inside the chute 16. When the slider 17 moves, it drives the adjusting plate 11 to move synchronously. At this time, under the elastic force of the first spring 13, the adjusting plate 11 drives the clamp 4 to move synchronously.

[0022] The moving mechanism includes a cross plate 18. The cross plate 18 is fixedly connected to the vertical plate 3 through a power component. On the side of the cross plate 18 close to the bending member 14, a connecting plate 19 is rotatably installed. One end of the connecting plate 19 away from the cross plate 18 is rotatably connected to the slider 17.

[0023] The power assembly includes an electric push rod 22, which is fixedly installed on one side of the vertical plate 3 close to the fixture 4. The output end of the electric push rod 22 is fixedly connected to the cross plate 18. An installation block 21 is fixedly installed on one side of the cross plate 18 close to the vertical plate 3. A groove 20 is formed on the surface of the vertical plate 3, and the groove 20 is slidably connected to the installation block 21.

[0024] Connect the electric push rod 22 to an external power source. The electric push rod 22 drives the cross plate 18 to move up and down. At this time, the installation block 21 slides inside the groove 20. When the cross plate 18 moves, it drives the connecting plate 19 to rotate. When the cross plate 18 moves upward, the connecting plate 19 drives the two groups of sliders 17 to move away from each other. When the cross plate 18 moves downward, the connecting plate 19 drives the two groups of sliders 17 to move closer to each other.

[0025] The support mechanism includes limit blocks 8. The number of limit blocks 8 is at least two groups. Protrusions 9 are fixedly installed on the adjacent sides of the two groups of limit blocks 8. A support frame 10 is fixedly installed outside the limit blocks 8. The support frame 10 is slidably connected to the fixture 4. A push plate 12 is rotatably installed at one end of the support frame 10 close to the adjustment plate 11. One end of the push plate 12 away from the support frame 10 is rotatably connected to the adjustment plate 11.

[0026] Specifically, after the fixture 4 contacts the pipe fitting and stops moving, at this time, the adjustment plate 11 moves towards the fixture 4. The adjustment plate 11 drives the support frame 10 to move closer to each other inside the fixture 4 through the push plate 12. The support frame 10 drives the limit blocks 8 to move. The limit blocks 8 can clamp the pipe fitting from the outside. Under the action of the protrusions 9, the friction between the limit blocks 8 and the pipe fitting can be increased, and the stability of the pipe fitting can be improved.

[0027] The limit mechanism includes a baffle 23 and a movable groove 24. The movable groove 24 is formed on the surface of the vertical plate 3. The baffle 23 is slidably installed inside the movable groove 24. A second spring 25 is fixedly installed inside the movable groove 24. The second spring 25 is fixedly connected to the baffle 23. An adjustment assembly connected to the adjustment plate 11 is arranged outside the baffle 23.

[0028] The adjustment assembly includes an adjustment block 26 and an installation groove 27. The installation groove 27 is formed on one side of the fixture 4 close to the adjustment plate 11. A cross bar 28 is fixedly installed inside the installation groove 27. The cross bar 28 is slidably connected to the adjustment block 26. A third spring 29 is movably sleeved on the outer surface of the cross bar 28. The third spring 29 is fixedly connected to the adjustment block 26. The adjustment block 26 is in contact and cooperation with the baffle 23. A fixed block 30 is fixedly installed on one side of the adjustment plate 11 close to the fixture 4. The fixed block 30 is in contact and cooperation with the adjustment block 26.

[0029] Specifically, when the adjusting plate 11 moves towards the fixture 4, the adjusting plate 11 drives the fixed block 30 to move synchronously. The fixed block 30 contacts the adjusting block 26 and drives the adjusting block 26 to move away from the fixture 4. At this time, under the action of the installation groove 27, the adjusting block 26 slides on the outer surface of the cross bar 28, and the third spring 29 deforms under force. When the adjusting block 26 moves, it contacts the baffle 23 and pushes the baffle 23 into the movable groove 24. At this time, the second spring 25 is compressed under force, and the baffle 23 no longer limits the bent part 14. The cross plate 18 continues to move downward, thereby driving the bent part 14 to rotate around the rotating shaft 15.

[0030] A pipe 33 is fixedly inserted inside the adjusting plate 11. A through hole 32 is opened inside the fixture 4. The through hole 32 is slidably connected to the pipe 33. A sealing member 31 is fixedly installed on the side of the fixture 4 away from the adjusting plate 11.

[0031] Specifically, under the action of the sealing member 31, the sealing performance between the two ends of the pipe fitting and the fixture 4 can be enhanced. When the adjusting plate 11 moves towards the fixture 4, it can drive the pipe 33 to penetrate through the through hole 32, enabling the pipe 33 to enter the interior of the pipe fitting. Air or water is conveyed into the pipe fitting through the pipe 33, which can detect the welding effect and simultaneously cool the pipe fitting.

[0032] Working principle: Place the pipe fitting to be processed above the supporting plate 35, connect the electric push rod 22 to an external power source. The electric push rod 22 drives the cross plate 18 to move up and down. At this time, the mounting block 21 slides inside the groove 20. When the cross plate 18 moves, it drives the connecting plate 19 to rotate. When the cross plate 18 moves upward, the connecting plate 19 drives the two sliders 17 to move away from each other. When the cross plate 18 moves downward, the connecting plate 19 drives the two sliders 17 to move closer to each other.

[0033] The two sliders 17 move closer to or away from each other inside the sliding groove 16. When the sliders 17 move, they drive the adjusting plate 11 to move synchronously. At this time, under the elastic force of the first spring 13, the adjusting plate 11 drives the fixture 4 to move synchronously.

[0034] After the fixture 4 contacts the pipe fitting and stops moving, at this time, the adjusting plate 11 moves towards the fixture 4. The adjusting plate 11 drives the support frames 10 to move closer to each other inside the fixture 4 through the push plate 12. The support frames 10 drive the limit blocks 8 to move. The limit blocks 8 can clamp the pipe fitting from the outside. Under the action of the protrusions 9, the friction between the limit blocks 8 and the pipe fitting can be increased. At this time, the cutting member 5 cuts the pipe fitting.

[0035] When the adjusting plate 11 moves towards the fixture 4, the adjusting plate 11 drives the fixed block 30 to move synchronously. The fixed block 30 contacts the adjusting block 26 and drives the adjusting block 26 to move away from the fixture 4. At this time, under the action of the installation groove 27, the adjusting block 26 slides on the outer surface of the cross bar 28, and the third spring 29 deforms under force. When the adjusting block 26 moves, it contacts the baffle 23 and pushes the baffle 23 into the inner part of the movable groove 24. At this time, the second spring 25 is compressed under force, and the baffle 23 no longer limits the bent part 14. The cross plate 18 continues to move downward, so as to drive the bent part 14 to rotate around the rotating shaft 15. Under the action of the fixing frame 6, the welding part 7 welds the bent fixing frame 6.

[0036] Under the action of the sealing member 31, the sealing performance between both ends of the pipe fitting and the fixture 4 can be increased. When the adjusting plate 11 moves towards the fixture 4, it can drive the pipeline 33 to penetrate through the through hole 32, so that the pipeline 33 enters the interior of the pipe fitting, and air or water is conveyed into the pipe fitting through the pipeline 33.

[0037] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
