[0002] The pressure vessel nozzle is used to connect the pressure vessel and the external pipeline system to realize the inlet and outlet of various working media. The nozzle material is usually selected as high-strength steel or alloy material matching the main body material of the pressure vessel to ensure that the nozzle can withstand the pressure of the internal medium and the influence of the external environment during operation. When in use, it is ensured that the seal between the nozzle and the pressure vessel is good. Through appropriate welding processes and techniques, a good seal between the nozzle and the pressure vessel can be achieved.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] Referring to Figure 1 、 Figure 2 and Figure 3 , an embodiment provided by the present utility model: A novel welding auxiliary tool for a connecting pipe of a pressure vessel includes a mounting member 1. An activity groove 10 is provided inside the mounting member 1. A motor 7 is fixedly connected to the inner bottom wall of the activity groove 10. A fixed member 8 is fixedly connected to the inner bottom wall of the activity groove 10. A turntable 6 is fixedly connected to the top of the fixed member 8. Two connecting members 9 are rotatably connected to the outside of the turntable 6. Two slide rods 5 are fixedly connected to the outside of the fixed member 8. A slide block 4 is slidably connected to the outside of the slide rod 5. A guide rod 3 is fixedly connected to the top of the slide block 4. A clamping member 19 is fixedly connected to the outside of the guide rod 3. Two support grooves 2 are provided at the top of the mounting member 1. A buffer assembly is installed at the top of the mounting member 1, and the buffer assembly is used to buffer the connecting pipe.
[0030] Furthermore, first place the connecting pipe at the specified position, start the motor 7, and the output end of the motor 7 drives the turntable 6 to rotate, and then drives the connecting member 9 to rotate at the same time. Under the traction of the connecting member 9, the two sliders 4 are moved closer to each other along the outside of the slide rod 5, and then drive the guide rod 3 to slide along the inner wall of the support groove 2. The two clamping members 19 are driven closer to each other through the guide rod 3, and the connecting pipe is clamped and fixed by the clamping member 19, which can effectively prevent the connecting pipe from being displaced during the welding process, so that the weld is always kept in a stable state, and the consistency of the welding quality is guaranteed.
[0031] Reference Figure 1 and Figure 3 The buffer assembly includes two bottom plates 17, the bottom of the bottom plates 17 is fixedly connected to the top of the mounting member 1, the top of the bottom plates 17 is fixedly connected to two connecting blocks 12, the inner side of the connecting block 12 is fixedly connected to a transmission rod 13, the outer side of the transmission rod 13 is sleeved with a spring 15, the outer side of the transmission rod 13 is slidably connected to two synchronization blocks 14, the top of the synchronization block 14 is rotatably connected to a transfer rod 16, and the other end of the transfer rod 16 is rotatably connected to a buffer block 11; one end of the spring 15 is fixedly connected to the outer side of one of the synchronization blocks 14, and the other end of the spring 15 is fixedly connected to the outer side of the other synchronization block 14; four telescopic rods 18 are fixedly connected to the top of the mounting member 1, and the other end of each two telescopic rods 18 is fixedly connected to the bottom of the buffer block 11.
[0032] Furthermore, in addition, the bottom of the connecting pipe contacts the top of the buffer block 11, so that the buffer block 11 moves downward, and then drives the two synchronous blocks 14 to slide toward each other along the outside of the transmission rod 13 through the transfer rod 16, squeezing the spring 15. At this time, the impact force on the connecting pipe is consumed by the elastic potential energy of the spring 15. During the welding process, the connecting pipe is buffered by the elastic force of the spring 15 to reduce shaking. By buffering the connecting pipe, part of the energy and stress generated by welding can be absorbed, reducing the impact on the pressure vessel body and reducing the probability of structural deformation; the spring 15 is limited by the two synchronous blocks 14, so that the internal force of the spring 15 is more uniform; the function of the telescopic rod 18 is to limit the buffer block 11, so that the buffer block 11 is more stable, further improving the welding quality of the connecting pipe.
[0033] Reference Figure 1 , Figure 2 and Figure 3, one end of the connecting member 9 away from the turntable 6 is rotatably connected to the outer side of the slider 4, and one end of the sliding rod 5 away from the fixing member 8 is fixedly connected to the inner wall of the movable groove 10; the longitudinal section of the guiding rod 3 is square, and the outside of the guiding rod 3 is slidably connected to the inner wall of the supporting groove 2; an anti-slip pad is fixedly connected to the inner side of the clamping member 19, and the shape of the clamping member 19 is designed in an arc shape; the output end of the motor 7 is fixedly connected to the bottom of the turntable 6.
[0034] Further, the turntable 6 driven by the output end of the motor 7 rotates, and then the turntable 6 drives the slider 4 to slide along the outside of the sliding rod 5 through the connecting member 9. The sliding rod 5 is connected to the inner wall of the movable groove 10 to ensure the stability of the sliding rod 5; the slider 4 drives the guiding rod 3 to slide along the inner wall of the supporting groove 2, making the guiding rod 3 more stable, and then improving the reliability of the clamping member 19; the function of the anti-slip pad is to increase the friction of the clamping member 19, making the pipe to be welded more stable during welding, which helps to improve the welding quality.
[0035] Working principle: First, place the pipe to be welded at the designated position, start the motor 7, the output end of the motor 7 drives the turntable 6 to rotate, and then the turntable 6 makes the two sliders 4 approach each other through the connecting member 9. Then, under the traction of the slider 4, the two clamping members 19 approach each other through the guiding rod 3, and the pipe to be welded is clamped and fixed by the clamping member 19. In this way, the pipe to be welded can be fixed at the position required by the design, ensuring that the connection angle and position with the main body of the pressure vessel are accurate and error-free, and the deviation can be controlled within a very small range.
[0036] In addition, the bottom of the pipe to be welded contacts the top of the buffer block 11, which causes the buffer block 11 to move downward, and then drives the transfer rod 16 to move simultaneously. Under the traction of the transfer rod 16, the two synchronous blocks 14 approach each other, squeezing the spring 15. At this time, the elastic potential energy of the spring 15 consumes the welding impact force received by the pipe to be welded. By buffering the pipe to be welded, the shaking is reduced, which helps to make the molten pool more stable during the welding process, reduce the fluctuation of the molten pool metal, so that the filling of the weld seam is more uniform, ensuring the quality and strength of the weld seam.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
