Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically relates to a welding equipment for flange combined pipe fittings. Background Technique

[0002] A flange combined pipe refers to a pipeline component with a flange, and the connection between pipelines and between pipelines and equipment is realized through the flange. It is widely used in various fields. When producing flange combined pipes, the flange needs to be welded to the pipeline to form a whole. When the existing automatic and semi-automatic arc welding equipment welds flange combined pipes, it is necessary to fix the flange and the pipeline separately, and then adjust their positions to align the flange and the pipeline to complete the welding work. The entire positioning and alignment process is rather troublesome and cannot fix the flange and the pipeline simultaneously while aligning them, simplify the operation steps of positioning and aligning the flange and the pipeline, improve the working efficiency of positioning and alignment, and further improve the working efficiency of welding the flange and the pipeline. Summary of the Invention

[0003] The purpose of the present invention is to provide a welding equipment for flange combined pipe fittings to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A welding equipment for flange combined pipe fittings includes a welding workbench, a motor is installed on the welding workbench, a rotating shaft is installed on the motor, and a welding part carrying component is installed on the rotating shaft; A pipe fitting adjusting component is installed on the welding part carrying component, and the pipe fitting adjusting component can adjust and position the pipe fitting; A flange adjusting component is also installed on the welding part carrying component, and the flange adjusting component can adjust and position the flange; The pipe fitting adjusting component is connected to the flange adjusting component and can drive the flange adjusting component to move; The pipe fitting adjusting component and the flange adjusting component can drive the pipe fitting and the flange to be adjusted synchronously, so as to clamp and fix the two while aligning them.

[0005] Preferably, the welding part carrying component includes a first welding platform and a second welding platform. The first welding platform supports and positions the pipe fitting, and the second welding platform supports and positions the flange.

[0006] Preferably, a connecting bridge plate is fixedly arranged at the upper end of the first welding platform, and the first welding platform is connected to the second welding platform through the connecting bridge plate.

[0007] Preferably, the pipe fitting adjustment assembly includes a threaded operating rod, a pipe fitting mating plate, and a pipe fitting top bar. The threaded operating rod is threadedly connected to the first welding base, and an eccentric top sleeve is provided on the threaded operating rod.

[0008] Preferably, the eccentric top sleeve can push the pipe fitting upward, and the threaded operating rod can drive the pipe fitting mating plate to move.

[0009] Preferably, the pipe fitting mating plate is installed on the first welding base, and pipe fitting top bars are symmetrically installed on the pipe fitting mating plate.

[0010] Preferably, the pipe fitting top bar is connected to the first welding base, and when the pipe fitting mating plate moves, it can drive the pipe fitting top bar to move.

[0011] Preferably, the pipe fitting top bar can push the pipe fitting and limit it from both sides of the pipe fitting.

[0012] Preferably, the flange adjustment assembly includes a driving sleeve plate and a flange limiting bar. The driving sleeve plate is installed on the second welding base, and the driving sleeve plate is connected to the flange limiting bar.

[0013] Preferably, the driving sleeve plate is connected to the threaded operating rod, and the driving sleeve plate can be driven to move by the threaded operating rod.

[0014] Preferably, the flange limiting bar is driven by the driving sleeve plate, and the flange limiting bar can adjust the position of the flange to achieve the positioning and fixing of the flange.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, with the following advantages: 1. When welding the flange and the pipe, place the flange on the flange limiting bar under the second welding base, place the pipe fitting on the eccentric top sleeve, and then rotate the threaded operating rod to drive the eccentric top sleeve to rotate and move, so as to achieve the alignment of the flange and the pipe fitting, and can realize the synchronous clamping and fixing of the flange and the pipe fitting. There is no need to fix the flange and the pipe fitting separately, which is very convenient and fast, and can realize the rapid synchronous positioning of the two, facilitating the work of the staff.

[0016] 2. When rotating the threaded operating rod, it rotates the eccentric top sleeve, which can then push the pipe fitting upward to the positioning height. At the same time, the threaded operating rod can also drive the pipe fitting mating plate to move. Then, under the action of the pipe fitting mating plate, the pipe fitting can be pushed towards the flange.

Finally, under the action of the flange limiting strip, the flange is clamped and positioned. Moreover, when the flange limiting strip moves, it will also drive the moving carrier block to move, thereby causing the pressing carrier frame to move towards the flange and press on the flange to fix the flange.

[0037] As Figure 1 and Figure 6 shown, the pipe fitting top bar 5 is connected to the first welding base 2.

One end of the plugging moving plate 51 away from the pipe fitting top bar 5 is hinged with a translation driving rod 53, and the other end of the translation driving rod 53 is hinged on a mating convex block 22.

[0038] As Figure 1 、 Figure 2 and Figure 9 shown, the flange adjusting assembly includes a driving sleeve plate 6 and a flange limiting bar 7. The driving sleeve plate 6 is installed on the second welding base 25, and the driving sleeve plate 6 is connected to the flange limiting bar 7. An activity sleeve hole 61 is formed in the driving sleeve plate 6, and a support column body 28 is inserted into the activity sleeve hole 61. A reset spring 62 is sleeved on the support column body 28. The two ends of the reset spring 62 are respectively fixed on the driving sleeve plate 6 and a limiting plate block 29. Connecting carriers 63 are fixedly arranged on the driving sleeve plate 6 in a circumferential manner. A pulling connecting rod 64 is hinged on the connecting carrier 63, and the other end of the pulling connecting rod 64 is hinged on the flange limiting bar 7. A bent mating plate frame 65 is fixedly arranged on the connecting carrier 63 on the lower side of the driving sleeve plate 6. The other end of the bent mating plate frame 65 is fixedly provided with an upwardly warped plate strip 66. A bearing channel 67 is formed at the upper end of the upwardly warped plate strip 66.

[0039] As Figure 8As shown, the driving sleeve plate 6 is connected to the threaded operating rod 3. The driving sleeve plate 6 can be driven to move through the threaded operating rod 3. A mating load column 34 is fixedly arranged at the end of the threaded operating rod 3. The mating load column 34 is inserted into the bearing channel 67 on the upwardly curved strip 66, and the upwardly curved strip 66 is in contact with the end of the threaded operating rod 3.

[0040] As Figure 2 , Figure 3 and Figure 10 shown, the flange limiting strip 7 is driven by the driving sleeve plate 6. The flange limiting strip 7 can adjust the position of the flange to achieve the positioning and fixing of the flange. The flange limiting strip 7 is inserted into the connection channel 26. Symmetrically arranged activity grooves 71 are formed on the flange limiting strip 7. The inner wall of the activity grooves 71 is smooth and burr-free. Moreover, a limiting activity hole 72 is formed at one end of the flange limiting strip 7. A channel built-in rod 261 is inserted into the limiting activity hole 72. In addition, a moving load block 73 is installed on the flange limiting strip 7. Symmetrically arranged moving load columns 74 are fixedly arranged on the moving load block 73. The moving load columns 74 are inserted into the driving channels 271 on the displacement strip 27, and the moving load columns 74 are in contact with the inner wall of the driving channels 271. Symmetrically arranged activity insertion plates 75 are also fixedly arranged on the moving load block 73. The activity insertion plates 75 are inserted into the activity grooves 71. A pressing load frame 76 is fixedly arranged at the end of the activity insertion plate 75 far from the moving load block 73. The pressing load frame 76 can press and fix the flange.

[0041] When welding between a flange and a pipe fitting, place the pipe fitting on the eccentric top sleeve 33 on the threaded operating rod 3. At the same time, place the flange on the flange limiting strip 7 on the lower side of the second welding base 25, and support and limit it through the flange limiting strip 7. Then, at this time, the threaded operating rod 3 can be rotated to move in the direction of the second welding base 25 under the action of the thread. In this way, as the threaded operating rod 3 rotates, the end with a large eccentricity on the eccentric top sleeve 33 will rotate upwards until it reaches the uppermost end. At this time, the limiting end block 451 on the guiding and fitting rod 45 contacts the end face of the first welding base 2, and the threaded operating rod 3 can no longer move forward. In the process of the rotation of the eccentric top sleeve 33, it will push the pipe fitting upwards. When the threaded operating rod 3 moves, since the plug-in turntable 31 on the threaded operating rod 3 is plugged into the plug-in rotating groove 46 on the pipe fitting matching plate 4, the threaded operating rod 3 will also drive the pipe fitting matching plate 4 to move away from the first welding base 2 when it moves, and further drive the pipe fitting top strip 5 to move away from the first welding base 2. In this way, under the action of the translation driving rod 53, the two pipe fitting top strips 5 will move towards each other. When the pipe fitting contacts one of the pipe fitting top strips 5, it can be pushed by the pipe fitting top strip 5 until both pipe fitting top strips 5 contact the pipe fitting. In this way, the pipe fitting can be limited and clamped from both sides by the two pipe fitting top strips 5, that is, when the pipe fitting moves upwards under the action of the eccentric top sleeve 33, it will also move horizontally under the action of the pipe fitting top strip 5. At the same time, under the action of the pipe fitting matching plate 4, the pipe fitting can be pushed towards the flange. When the pipe fitting moves upwards, it finally contacts the upper limiting strip 41 on the pipe fitting matching plate 4. In this way, under the combined action of the eccentric top sleeve 33, the pipe fitting top strip 5 and the upper limiting strip 41, the pipe fitting can be accurately positioned and clamped. In addition, since the threaded operating rod 3 contacts the upwardly warped strip 66 on the bent fitting plate frame 65, the threaded operating rod 3 will push the upwardly warped strip 66 to move when it moves, and thus can drive the driving sleeve plate 6 to move, making the driving sleeve plate 6 move away from the second welding base 25. As the driving sleeve plate 6 moves, the return spring 62 will be in a compressed state. At the same time, as the driving sleeve plate 6 moves, under the action of the pulling connecting rod 64, the flange limiting strip 7 on the second welding base 25 that does not contact the flange will be pulled towards the flange. At the same time, under the action of the lower flange limiting strip 7 on the second welding base 25, the flange will be pushed upwards. Finally, all the flange limiting strips 7 contact the flange. In this way, the flange can be clamped and its position adjusted to align the flange with the pipe fitting. When the flange limiting strip 7 moves, since the moving carrier column 74 on the moving carrier block 73 is plugged into the driving channel 271, as the flange limiting strip 7 moves, the moving carrier column 74 will move along the driving channel 271.In this way, under the driving action of the driving channel 271, the moving carrier block 73 will be driven to move relative to the flange limiting strip 7, so that the pressing carrier frame 76 on the moving carrier block 73 can be pressed against the end face of the carrier flange, realizing the complete fixation of the flange. At this time, the pipe fitting and the flange are in contact and aligned, and the two can be welded. During the welding process, the first welding base 2 and the second welding base 25 can be driven to rotate by the motor 12 to adjust the welding position, facilitating the welding work of the flange and the pipe fitting. The operation is simple, convenient and fast. There is no need to fix the flange and the pipe fitting separately. Just rotating the threaded operating rod 3 can realize the synchronous adjustment of the positions of the flange and the pipe fitting, making the two aligned. At the same time, it can also realize the clamping and fixation of the flange and the pipe fitting, ensuring the stability of the flange and the pipe fitting during the welding process. After the welding is completed, rotating the threaded operating rod 3 in the reverse direction will drive the threaded operating rod 3 to move in the reverse direction under the action of the thread. With the reverse movement of the threaded operating rod 3, under the action of the return spring 62, the driving sleeve plate 6 will be driven to move in the reverse direction, driving the flange limiting strip 7 to reset, so that the flange limiting strip 7 releases the flange, and the pressing carrier frame 76 no longer presses the flange. At the same time, due to the rotation of the eccentric top sleeve 33, the pipe fitting is no longer supported by the eccentric top sleeve 33. It moves downward together with the flange, and the pipe fitting top strip 5 moves away from each other, no longer restricting the pipe fitting. Finally, the pipe fitting is also released, and thus the welded flange combination pipe can be removed.
