[0002] Pipe welding is to connect two independent pipes together by welding, so as to increase the length of the pipes and facilitate people's use. During the pipe welding process, in order to ensure the quality of pipe welding, the pipes need to be fixed, and at this time, a special fixture for pipe welding is required.

[0003] Some solutions have also been proposed for the welding of pipes in the prior art. For example, a patent application with the publication number CN221658439U discloses a pipe support welding fixture, belonging to the field of welding fixtures, including a bottom plate. A rotating assembly is arranged on the top of the bottom plate, a boss is fixedly connected to the middle of the upper end of the bottom plate, a power mechanism is arranged on the top of the boss, the power mechanism is connected to the rotating assembly, and two fixing assemblies are arranged on the back of the rotating assembly. The rotating assembly includes two brackets, and the bottom parts of the brackets are respectively fixedly connected to both sides of the top of the bottom plate.

[0004] Although the above technical solution solves the problem of clamping the pipe support, there are still other problems in actual use. For example, when welding pipes, it is necessary to butt the welding points of the two pipes together and then weld the two surfaces at the welding place. However, it is more troublesome to weld the two surfaces of the pipes.

[0005] Therefore, the present invention provides a pipe welding fixture. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

Two transfer tables are installed above the workbench. Guide frames are installed in the transfer directions of the two transfer tables. A first pipe to be welded and a second pipe to be welded are respectively arranged above the two guide frames. The two guide frames are respectively used to guide the first pipe to be welded and the second pipe to be welded to be butted together. A rotating gear disc is rotatably arranged on the side wall of the workbench through a support rod. A welding seat is arranged on the inner wall of the rotating gear disc. A welding head is installed at the end of the welding seat. The welding head is used to weld the butting points of the first pipe to be welded and the second pipe to be welded that are butted together.

The limiting ring is rotatably arranged inside the limiting circular frame, and a circular groove adapted to the limiting ring is provided inside the limiting circular frame; during operation, when the rotating gear disc rotates, the limiting ring on its side wall will be driven to rotate at the same time, and the limiting ring will rotate inside the limiting circular frame. The design of the limiting ring and the limiting circular frame can limit the rotation of the rotating gear disc and avoid the problem that the rotating gear disc breaks away from above the workbench, and it is also convenient for welding the pipe to be welded.

[0012] Preferably, a rectangular seat is installed on the inner wall of the rotating gear disc. The welding seat is slidably arranged inside the rectangular seat. An electric telescopic column is installed on the side wall of the rectangular seat. The telescopic end of the electric telescopic column is connected to the side wall of the welding seat. A visual sensor is installed on the outer wall of the rectangular seat. The visual sensor is connected to an external controller through a power line; during operation, when the welding head of the welding seat welds the welding part, first move the welding seat to the edge of the welding part through the electric telescopic column, and then the welding head first performs preliminary welding treatment on the edge points of the welding part. Subsequently, under the drive of the electric telescopic column, the welding seat can be moved along the edge points of the welding part to another edge point, and the visual sensor will continuously observe the welding effect of the part to be welded. When the welding of the part to be welded is completed, the visual sensor will generate a welding completion signal and transmit it to the external controller. Then, the external controller first controls the welding seat to stop welding and controls the external motor to drive the rotating shaft to rotate, so that the rotating shaft drives the driving gear to rotate, the driving gear drives the rotating gear disc to rotate, and the welding seat rotates to the welding part on the other side.

[0013] Preferably, a baffle is slidably arranged inside each of the guiding frames. There are two baffles inside one of the guiding frames. The baffles are used to support the pipes to be welded. A linkage unit is arranged on the outer peripheral surface of the first electric telescopic rod.

[0015] Preferably, an embedding groove is formed at a position corresponding to the baffle inside the guiding frame. The embedding groove penetrates to the inside of the guiding frame. A limiting rod is arranged above the baffle, and the limiting rod is slidably arranged inside the guiding frame; during operation, the embedding groove is designed to facilitate the movement of the baffle along the inside of the guiding frame, so as to facilitate the recovery treatment of the welded pipes.

[0016] Preferably, a guiding recovery frame is arranged above the workbench and below the guiding frame; the guiding recovery frame is designed to facilitate the recovery of the welded pipes.

[0017] The beneficial effects of the present invention are as follows: 1. For the pipe welding fixture of the present invention, by driving the movement of the welding seat by the electric telescopic column, the welding seat can be moved along the edge point of the welding part to another edge point, and the visual sensor will always observe the welding effect of the part to be welded. After the part to be welded is welded, the visual sensor will generate a welding completion signal and transmit it to the external controller. Then, the external controller first controls the welding seat to stop welding, and controls the external motor to drive the rotation shaft to rotate, so that the rotation shaft drives the driving gear to rotate, and the driving gear will drive the rotating gear disc to rotate, and the welding seat will rotate to the welding part on the other side.

[0018] 2. For the pipe welding fixture of the present invention, the linkage bracket will first move on the inner wall of the rectangular groove. When the linkage bracket moves from the inner wall of the rectangular groove and moves to the other end of the rectangular groove, at this time, the linkage bracket will continue to drive the baffle to move, that is, the two baffles move away from each other, that is, the fastening head first moves away from the welded pipe for a certain period of time, and then the baffle will start to move. In this way, it can ensure that the pipe to be welded can fall along the recovery groove to the lower part, realizing the automatic recovery treatment of the pipe to be welded.

Detailed implementation manners

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0023] Such as Figures 1 to 4As shown in the figure, a pipe welding fixture according to an embodiment of the present invention is characterized in that: it includes a workbench 1, two transfer tables 2 are installed above the workbench 1, and guide frames 3 are installed in the transfer directions of the two transfer tables 2. Above the two guide frames 3 are respectively arranged a first pipe to be welded 301 and a second pipe to be welded 302. The two guide frames 3 are respectively used to guide the first pipe to be welded 301 and the second pipe to be welded 302 to be butted together. A rotary gear disk 4 is rotatably arranged on the side wall of the workbench 1 through a support rod. A welding seat 5 is arranged on the inner wall of the rotary gear disk 4. A welding head is installed at the end of the welding seat 5. The welding head is used to weld the butting points of the first pipe to be welded 301 and the second pipe to be welded 302 that are butted together. The rotary gear disk 4 is used to rotate the welding seat 5 and weld the remaining butting points of the first pipe to be welded 301 and the second pipe to be welded 302. A clamping unit is arranged inside the guide frame 3. The clamping unit is used to clamp and fix the first pipe to be welded 301 and the second pipe to be welded 302; during work, refer to the appendix Figure 1 As shown in the figure, when welding two frame pipes into a 90-degree state, that is, first place the first pipe to be welded 301 and the second pipe to be welded 302 into the two guide frames 3 respectively, and move the first pipe to be welded 301 and the second pipe to be welded 302 to the appendix Figure 3 shown position, that is, the welding point to be welded corresponds to the welding point of the welding seat 5. Then, the welding head of the welding seat 5 can be used to perform welding treatment on the welding point to be welded. After welding one side of the welding point of the two pipes is completed, by rotating the rotary gear disk 4 by 180 degrees, the welding seat 5 can be driven to rotate to the other welding point, thus improving the welding effect of the pipes and being beneficial to the subsequent polishing of the pipes.

[0024] It should be noted that the welding method of the welding seat 5 and the welding head is a prior art and will not be elaborated in the embodiment of the present invention.

[0025] The clamping unit includes guide seats 6 installed on the inner walls of the two guide frames 3. Electric telescopic rods 601 are installed on the opposite surfaces of the two guide seats 6. Tightening heads 7 are installed at the telescopic ends of the two electric telescopic rods 601. The two tightening heads 7 are used to clamp the pipe to be welded. The material of the tightening head 7 is rubber; during work, when the first pipe to be welded 301 and the second pipe to be welded 302 are placed inside the guide frame 3, refer to the appendix Figure 3As shown, the pipe to be welded is located between the corresponding two fastening heads 7 at this time. Then, the telescopic end of the first electric telescopic rod 601 is controlled to move, so that the first electric telescopic rod 601 drives the corresponding fastening head 7 to move, and the two fastening heads 7 press on the side wall of the pipe to be welded, realizing the clamping treatment of the pipe to be welded. In this way, it is convenient for the welding of the pipe to be welded, and it can be applied to pipes to be welded with different widths, improving the practicability of the present invention.

[0026] An electric telescopic rod two 303 is installed on the side wall of each guiding frame 3. The telescopic end of the electric telescopic rod two 303 is connected to the side wall of the guiding seat 6. A sliding groove adapted to the guiding seat 6 is formed in the inner wall of the guiding frame 3. During work, when the first pipe to be welded 301 and the second pipe to be welded 302 are fixed by the corresponding fastening heads 7, then the electric telescopic rod two 303 corresponding to each guiding frame 3 is controlled to operate, so that the telescopic end of the electric telescopic rod two 303 pushes the guiding seat 6 to move, and the guiding seat 6 moves along the inner wall of the guiding frame 3. At this time, the two guiding seats 6 will approach each other, that is, the first pipe to be welded 301 and the second pipe to be welded 302 will approach each other and move to the position shown in the reference appendix Figure 3 At this position, the welding joints of the two pipes to be welded will come into contact with each other. Due to the design of the guiding frame 3 and the guiding seat 6, when the two pipes to be welded are fixed inside the guiding frame 3 and are pushed, under the guiding and limiting of the guiding seat 6 and the guiding frame 3, the two pipes to be welded can be butted together without error, improving the welding forming quality of the two pipes to be welded, which is beneficial to the subsequent use and reprocessing of the pipes to be welded.

[0027] As Figures 2 to 6 shown, a connecting bracket 8 is installed above the workbench 1. A rotating shaft 9 is rotatably installed on the side wall of the connecting bracket 8. A driving gear 10 is installed at the end of the rotating shaft 9 away from the connecting bracket 8. The end of the rotating shaft 9 away from the driving gear 10 is connected to the output end of an external motor. The driving gear 10 is meshed and connected with the rotating tooth disc 4. During work, referring to the reference appendix Figure 1 and Figure 6 shown, the welding seat 5 is installed on the inner wall of the rotating tooth disc 4, and the welding head of the welding seat 5 corresponds to the welding joint of the pipe to be welded. After one side of the welding joint is welded by the welding head, first stop the welding of the welding seat 5, and then control the external motor to drive the rotating shaft 9 to rotate. The rotating shaft 9 drives the driving gear 10 to rotate. The driving gear 10 drives the rotating tooth disc 4 meshed with it to rotate, so that the rotating tooth disc 4 drives the welding seat 5 to rotate to the welding joint on the other side of the pipe to be welded. Then, the welding head of the welding seat 5 can continue to weld the pipe to be welded.

[0028] A limiting ring 11 is installed on the side wall of the rotating gear disk 4. Above the workbench 1, a limiting circular frame 12 is installed through a side bracket. The limiting ring 11 is rotatably arranged inside the limiting circular frame 12, and a circular groove adapted to the limiting ring 11 is opened inside the limiting circular frame 12. During operation, when the rotating gear disk 4 rotates, the rotating gear disk 4 will drive the limiting ring 11 on its side wall to rotate simultaneously. The limiting ring 11 will rotate inside the limiting circular frame 12. The design of the limiting ring 11 and the limiting circular frame 12 can limit the rotating gear disk 4 during rotation, avoid the problem that the rotating gear disk 4 breaks away from above the workbench 1, and also facilitate the welding of the pipe to be welded.

[0029] As Figures 3 to 8 shown, a rectangular seat 13 is installed on the inner wall of the rotating gear disk 4. The welding seat 5 is slidably arranged inside the rectangular seat 13. An electric telescopic column 14 is installed on the side wall of the rectangular seat 13. The telescopic end of the electric telescopic column 14 is connected to the side wall of the welding seat 5. A visual sensor 131 is installed on the outer wall of the rectangular seat 13. The visual sensor 131 is connected to an external controller through a power line. During operation, when the welding head of the welding seat 5 welds the welding point, first, the electric telescopic column 14 moves the welding seat 5 to the edge of the welding point. Then, the welding head first performs preliminary welding treatment on the edge point of the welding point. Subsequently, under the drive of the electric telescopic column 14, the welding seat 5 can be moved along the edge point of the welding point to another edge point. And the visual sensor 131 will continuously observe the welding effect of the pipe to be welded. When the welding of the pipe to be welded is completed, the visual sensor 131 will generate a welding completion signal and transmit it to the external controller. Then, the external controller first controls the welding seat 5 to stop welding, and controls the external motor to drive the rotating shaft 9 to rotate, so that the rotating shaft 9 drives the driving gear 10 to rotate. The driving gear 10 will drive the rotating gear disk 4 to rotate, and make the welding seat 5 rotate to the welding point on the other side; It should be noted that the visual sensor 131 is mainly composed of one or two graphic sensors, which can be a CCD camera, and is used to obtain the welding effect of the welding head on the pipe to be welded, that is, the welding completion degree.

[0030] A baffle 15 is slidably arranged inside each guide frame 3. There are two baffles 15 inside one of the guide frames 3. The baffle 15 is used to support the pipe to be welded. A linkage unit is arranged on the outer peripheral surface of the first electric telescopic rod 601. When the first electric telescopic rod 601 moves, it will drive the baffle 15 to move through the linkage unit. During operation, refer to the attached Figure 6 and Figure 8As shown, after the first pipe to be welded 301 and the second pipe to be welded 302 are fixed, at this time, the first pipe to be welded 301 and the second pipe to be welded 302 are located above the baffle 15. When both sides of the welding joint are welded, the visual sensor 131 will also transmit the welding completion signal to the external controller, causing the external controller to drive the first electric telescopic rod 601 to move. The telescopic end of the first electric telescopic rod 601 drives the corresponding fastening head 7 away from the welded pipe. Then, through the action of the linkage unit, the corresponding two baffles 15 can be made to move away from each other, and the welded pipe will fall along the gap where the two baffles 15 separate and be recycled below.

[0031] As Figures 4 to 10 shown, the linkage unit includes a linkage bracket 16 fixedly installed on the outer peripheral surface of the first electric telescopic rod 601. A rectangular groove 17 is formed on the lower peripheral surface of the baffle 15. The side of the linkage bracket 16 away from the first electric telescopic rod 601 is slidably disposed inside the rectangular groove 17. Inside the guiding frame 3 and below the baffle 15, a recycling groove 305 is provided. During operation, referring to the attached Figure 9 figure, the end of the linkage bracket 16 is located on one side of the groove wall of the rectangular groove 17. When the telescopic end of the first electric telescopic rod 601 drives the fastening head 7 away from the welded pipe, the telescopic end of the first electric telescopic rod 601 will simultaneously drive the linkage bracket 16 to move. The linkage bracket 16 will first move on the inner wall of the rectangular groove 17. When the linkage bracket 16 moves from the inner wall of the rectangular groove 17 and moves to the other end of the rectangular groove 17, that is, when the linkage bracket 16 moves inside the rectangular groove 17 from the attached Figure 9 to the attached Figure 10 figure, at this time, the linkage bracket 16 will continue to drive the baffle 15 to move, that is, the two baffles 15 move away from each other. That is, after the fastening head 7 moves away from the welded pipe for a certain period of time, the baffle 15 will start to move. In this way, it can be ensured that the pipe to be welded can fall along the recycling groove 305 to the lower part, realizing the automatic recycling process of the pipe to be welded.

[0032] At the corresponding position of the guiding frame 3 and the baffle 15 inside, an embedding groove 18 is provided. The embedding groove 18 penetrates into the inside of the guiding frame 3. A limiting rod is arranged above the baffle 15, and the limiting rod is slidably disposed inside the guiding frame 3. During operation, the embedding groove 18 is designed to facilitate the movement of the baffle 15 along the inside of the guiding frame 3, thereby facilitating the recycling process of the welded pipe.

[0033] Above the workbench 1 and below the guiding frame 3, a guiding recycling frame 20 is provided. The guiding recycling frame 20 is designed to facilitate the recycling of the welded pipe.

[0034] During operation, when two box-shaped pipes are welded at a 90-degree angle, first place the first pipe to be welded 301 and the second pipe to be welded 302 in two guiding frames 3 respectively, and move the first pipe to be welded 301 and the second pipe to be welded 302 to the position shown in the appendix Figure 3 That is, the welding point of the part to be welded corresponds to the welding seat 5. Then, the welding head of the welding seat 5 can be used to perform welding treatment on the part to be welded. After one side of the parts to be welded of the two pipes is welded, by rotating the rotating gear disk 4 by 180 degrees, the welding seat 5 can be driven to rotate to the other side welding point, thus improving the welding effect of the pipes and being beneficial to the subsequent polishing of the pipes; when the first pipe to be welded 301 and the second pipe to be welded 302 are placed inside the guiding frame 3, as shown in the appendix Figure 3 Shown, at this time the pipes to be welded will be located between the corresponding two fastening heads 7. Then, control the telescopic end of the first electric telescopic rod 601 to move, so that the first electric telescopic rod 601 drives the corresponding fastening head 7 to move, and the two fastening heads 7 press on the side walls of the pipes to be welded, realizing the clamping treatment of the pipes to be welded. In this way, the welding of the pipes to be welded is convenient, and it can be applied to pipes to be welded with different widths, improving the practicability of the present invention; After the first pipe to be welded 301 and the second pipe to be welded 302 are fixed by the corresponding fastening heads 7, at this time, control the operation of the second electric telescopic rod 303 corresponding to each guiding frame 3, so that the telescopic end of the second electric telescopic rod 303 pushes the guiding seat 6 to move, and the guiding seat 6 moves along the inner wall of the guiding frame 3. And at this time, the two guiding seats 6 will approach each other, that is, the first pipe to be welded 301 and the second pipe to be welded 302 will approach each other and move to the position shown in the appendix Figure 3 Shown. At this time, the welding points of the two pipes to be welded will come into contact with each other. Due to the design of the guiding frame 3 and the guiding seat 6, when the two pipes to be welded are fixed inside the guiding frame 3 and are pushed, under the guiding and limiting of the guiding seat 6 and the guiding frame 3, the two pipes to be welded can be butted together without error, improving the welding forming quality of the two pipes to be welded and being beneficial to the subsequent use and reprocessing of the pipes to be welded; When the welding head of the welding seat 5 welds the welding area, first move the welding seat 5 to the edge of the welding area through the electric telescopic column 14. Then, the welding head first performs preliminary welding treatment on the edge points of the welding area. Subsequently, driven by the electric telescopic column 14 to move the welding seat 5, the welding seat 5 can be moved along the edge points of the welding area to another edge point, and the visual sensor 131 will continuously observe the welding effect of the area to be welded. When the welding of the area to be welded is completed, the visual sensor 131 will generate a welding completion signal and transmit it to the external controller. Then, the external controller first controls the welding seat 5 to stop welding, and controls the external motor to drive the rotating shaft 9 to rotate, so that the rotating shaft 9 drives the driving gear 10 to rotate. The driving gear 10 will drive the rotating gear disc 4 to rotate, and make the welding seat 5 rotate to the welding area on the other side; Refer to the appendix Figure 6 and Figure 8 As shown, after the first pipe to be welded 301 and the second pipe to be welded 302 are fixed, at this time, the first pipe to be welded 301 and the second pipe to be welded 302 are located above the baffle 15. When the two sides of the welding area are welded, the visual sensor 131 will also transmit the welding completion signal to the external controller, so that the external controller drives the first electric telescopic rod 601 to move. The telescopic end of the first electric telescopic rod 601 drives the corresponding fastening head 7 away from the welded pipe. Then, through the action of the linkage unit, the corresponding two baffles 15 can be separated from each other, and the welded pipe will fall down and be recycled along the gap where the two baffles 15 are separated; Refer to the appendix Figure 9 As shown, the end of the linkage bracket 16 is located on one side of the groove wall of the rectangular groove 17. When the telescopic end of the first electric telescopic rod 601 drives the fastening head 7 away from the welded pipe, the telescopic end of the first electric telescopic rod 601 will simultaneously drive the linkage bracket 16 to move. The linkage bracket 16 will first move on the inner wall of the rectangular groove 17. When the linkage bracket 16 moves from the inner wall of the rectangular groove 17 and moves to the other end of the rectangular groove 17, that is, when the linkage bracket 16 moves inside the rectangular groove 17 from Figure 9 to Figure 10 At this time, the linkage bracket 16 will continue to drive the baffle 15 to move, that is, the two baffles 15 are separated from each other. That is, after the fastening head 7 moves away from the welded pipe for a certain period of time, the baffle 15 will start to move. In this way, it can be ensured that the pipe to be welded can fall down along the recovery groove 305 to realize the automatic recovery treatment of the pipe to be welded.
