Description

Technical Field

[0001] This invention relates to the field of compensator welding technology, specifically a welded metal compensator. Background Technology

[0002] A metal compensator is a device used in piping systems. It is usually composed of components such as bellows, end pipes, flanges, and lugs. During welding, these components need to be welded in pairs. The welding of the bellows to the end pipes is the key part of welding a metal compensator. Both ends of the bellows need to be welded to the end pipes to connect the compensator to the piping system.

[0003] Traditionally, when welding compensators, the bellows and end pipe are placed directly on the rotating rollers of the operating table. Another person assists in aligning the ends of the bellows and end pipe, and then another operator performs the welding around the connection. As a result, the operator always needs to hold and align the bellows and end pipe during welding. Due to the limited operating space, this is inconvenient for the welding operator and results in low operating efficiency.

[0004] During the welding process, operators need to weld the connection between the bellows and the end pipe. Therefore, when it is necessary to adjust the angle between the two, the operators need to manually rotate the bellows and the end pipe. The operation is cumbersome, and the weld is prone to cracking when manually rotating the bellows and the end pipe, resulting in poor flexibility.

[0005] When performing a fully enclosed welding operation at the connection between the corrugated pipe and the end pipe, the operator usually walks around the workbench with a welding gun in hand. However, due to the low height of the workbench, the operator is required to bend over, resulting in low operating efficiency. Summary of the Invention

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the welding metal compensator of the present invention includes an operating table 1, an adjustment structure 2 mounted on the operating table 1, an extension structure 3 disposed on the adjustment structure 2, a fixing structure 4 connected to the extension structure 3, a limiting structure 5 cooperating with the fixing structure 4, an installation structure 6 mounted on the edge of the operating table 1, and a welding gun 7 disposed on the installation structure 6. The extension structure 3 includes a second guide rod 301 and an installation plate 302 slidably connected to the second guide rod 301. The adjustment structure 2 is fitted with the second guide rod 301. Two second guide rods 301 are fixedly connected to one side of the sliding plate 204, and a support plate 303 is fixedly connected to the other side of the sliding plate 204. A hydraulic rod is fixedly connected to the support plate 303. 304, the telescopic end of the hydraulic rod 304 is fixedly connected to a connecting plate 305, which is fixedly connected to the mounting plate 302. After the installation of the bellows and the end pipe is completed, the telescopic ends of the hydraulic rods 304 on the two support plates 303 extend outwards simultaneously. Then, the hydraulic rods 304 drive the mounting plate 302 to slide along the second guide rod 301 through the connecting plate 305 at the end. At this time, the mounting plate 302 drives the two symmetrical rotating sleeves 402 to move towards the middle simultaneously, thereby driving the bellows and the end pipe to move towards the middle simultaneously until the pipe openings of the bellows and the end pipe are aligned and abut against each other. At this time, the bellows and the end pipe can be welded. The operation is simple and avoids the problem of operators having to align the bellows and the end pipe during the welding process, thus improving the welding efficiency.

[0035] Specifically, such as Figures 1-3 and Figures 5-9As shown, the fixing structure 4 includes a rotating rod 401 and a rotating sleeve 402 rotatably connected to the rotating rod 401. The rotating rod 401 is rotatably connected to the center of the mounting plate 302. Four first mounting blocks 405 are fixedly connected to both ends of the rotating sleeve 402. A first rotating shaft 406 is fixedly connected to the first mounting block 405. A first rotating bar 407 is rotatably connected to the first rotating shaft 406. An abutment plate 412 is provided between two of the first rotating bars 407 located at both ends of the rotating sleeve 402. Three third rotating shafts 411 are fixedly connected to the bottom end of the abutment plate 412. Two of the first rotating bars 407 on the same plane are rotatably connected to two of the third rotating shafts 411. A second lead screw 403 is fixedly connected to the end of the rotating rod 401. A drive ring 404 is threaded onto the lead screw 403. Four second mounting blocks 408 are fixedly connected to the drive ring 404. A second rotating shaft 409 is fixedly connected to the second mounting block 408. A second rotating bar 410 is rotatably connected to the second rotating shaft 409. The second rotating bar 410 is rotatably connected to another third rotating shaft 411 on the contact plate 412. A limit structure 5 is fitted on the rotating sleeve 402. A second motor 414 is fixedly connected to the back of the mounting plate 302. The output shaft of the second motor 414 is fixedly connected to the rotating rod 401. A rubber pad 413 is fixedly connected to the contact plate 412. The first rotating bar 407 and the second rotating bar 410 are both "H" shaped structures. The end face of the contact plate 412 is a "convex" shaped structure.Then, the bellows and end pipe are respectively fitted onto the two rotating sleeves 402. First, the second motor 414 on the back of the mounting plate 302 drives the rotating rod 401 at the drive end to rotate counterclockwise. Then, the rotating rod 401 drives the second lead screw 403 at the end to rotate. At this time, the second lead screw 403 gives the drive ring 404 a counterclockwise rotational force. Since the drive ring 404 is connected to the rotating sleeve 402 through the abutment plate 412, it transmits the counterclockwise rotational force to the rotating sleeve 402. At this time, the rotating rod 401 and the rotating sleeve 402... Relative rotation occurs between the two components. The rotating rod 401 rotates counterclockwise inside the rotating sleeve 402. Since the drive ring 404 is threadedly connected to the second lead screw 403, and the drive ring 404 cannot rotate counterclockwise at this time, it is driven to move towards the second motor 414. During the movement of the drive ring 404, the first rotating bar 407 and the second rotating bar 410 rotate through the first rotating shaft 406 on the first mounting block 405 and the second rotating shaft 409 on the second mounting block 408, respectively. At this time, the rotating sleeve 402 rotates counterclockwise. The angle between the first rotating bar 407 at end 02 and the second rotating bar 410 on the drive ring 404 gradually decreases. Simultaneously, the first rotating bar 407 at the other end of the rotating sleeve 402 rotates towards the second motor 414. Since the tops of both the first rotating bar 407 and the second rotating bar 410 rotate with the contact plate 412 via the third rotating shaft 411, the contact plate 412 is kept in contact with the rotating sleeve as it rotates towards the second motor 414, ensuring that the contact plate 412 remains in contact with the rotating sleeve. The four contact plates 402 are kept parallel to each other until the rubber pads 413 on all four contact plates 412 are in close contact with the inner wall of the bellows. This completes the fixation of the bellows, ensuring strong stability. The rubber pads 413 also increase the friction between the bellows and the inner wall of the bellows. The same operation is repeated on the end pipe, causing the four contact plates 412 on the other end to press firmly against the inner wall of the end pipe. This effectively fixes the bellows and end pipe, improving stability and preventing the bellows or end pipe from falling off the operating table 1 during welding. The operation is simple.

[0036] Specifically, such as Figure 2 , Figure 6 and Figure 8As shown, the limiting structure 5 includes a mounting base 501 and a bearing 502 engaged with the mounting base 501. The mounting base 501 is fixedly connected to the front of the mounting plate 302. The bearing 502 is rotatably connected to the rotating sleeve 402. An inner ratchet 503 is fixedly connected inside the mounting base 501. A limiting block 505 is slidably connected to the end of the rotating sleeve 402. A first spring 504 is fixedly connected between the limiting block 505 and the inner wall of the rotating sleeve 402. The limiting block 505 engages with the... The inner ratchet 503 and the mounting base 501 have a "convex" shaped cross-section, while the limiting block 505 has a trapezoidal cross-section. The rotating sleeve 402 drives the limiting block 505 at the end to rotate. However, when there is a counterclockwise rotational force on the limiting block 505, the rotating sleeve 402 and the limiting block 505 are blocked from rotating due to the meshing between the limiting block 505 and the inner ratchet 503 inside the mounting base 501. During the welding process at the connection between the bellows and the end pipe, it is necessary to rotate and adjust the welding angle. At this time, the two ratchet 503... The second motor 414 on the back of the mounting plate 302 drives both rotating rods 401 to rotate clockwise. The rotating rods 401 then exert a clockwise force on the second lead screw 403 and drive ring 404 at their ends. The drive ring 404, through the contact plate 412, exerts a clockwise force on the rotating sleeve 402. Since the ratchet 503 does not obstruct the rotation of the limiting block 505 in the clockwise direction, the limiting block 505 slides inward into the rotating sleeve 402, compressing the first spring 504. At this time, due to the driving... The friction between ring 404 and second lead screw 403 is greater than the friction between limit block 505 and inner ratchet 503. At the same time, the end of rotating sleeve 402 is rotatably connected to mounting base 501 through bearing 502. Then, rotating rod 401 drives rotating sleeve 402 and bellows to rotate clockwise. The end tube at the other end of operating table 1 rotates clockwise at the same time. At this time, the bellows and end tube are effectively rotated during the welding process, which facilitates 360-degree welding at the connection between bellows and end tube. The operation is simple and flexible.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8As shown, the adjustment structure 2 includes a mounting frame 201 and a first guide rod 202 fixedly connected to the mounting frame 201. A mounting frame 201 is fixedly connected to each end of the operating table 1. A first lead screw 203 is rotatably connected to the mounting frame 201. A sliding plate 204 is provided between the first guide rod 202 and the first lead screw 203. The sliding plate 204 is slidably connected to the first guide rod 202, and the sliding plate 204 is threadedly connected to the first lead screw 203. The two mounting frames 201 are symmetrically arranged. A first motor 205 is fixedly connected to the top surface of 201, and the output shaft of the first motor 205 is fixedly connected to the first lead screw 203. The height of the clamp on the operating table 1 is adjusted according to the radius of the welded compensator. The first motors 205 on the two mounting brackets 201 drive the two first lead screws 203 to rotate respectively. Then, the first lead screws 203 drive the slide plate 204 to slide up and down along the first guide rod 202, thereby effectively adjusting the height of the clamp on the slide plate 204, ensuring that the center point of the corrugated pipe and the end pipe are on the same straight line, which is highly flexible.

[0038] Specifically, such as Figure 4 As shown, the installation structure 6 includes a support frame 601 and a telescopic plate 602 slidably connected inside the support frame 601. The support frame 601 is fixedly connected to the edge of the operating table 1. A knob 603 is threadedly connected to the support frame 601. The end of the knob 603 abuts against the telescopic plate 602. A rotating frame 604 is fixedly connected to the top of the telescopic plate 602. A fourth rotating shaft 605 is rotatably connected to the rotating frame 604. A clamp 606 is fixedly connected to the fourth rotating shaft 605. A locking block 608 is slidably connected to the end of the fourth rotating shaft 605. The locking block 608 engages with a groove on the outer wall of the rotating frame 604. A second spring 607 is fixedly connected between the locking block 608 and the end of the fourth rotating shaft 605. The end of the locking block 608 has a hexagonal structure. A welding gun 7 is fixedly connected to the clamp 606. When the wave is completed... After the corrugated pipe and end pipe are installed, the welding gun 7 is installed. Simply lock the welding gun 7 onto the clamp 606 at the top of the telescopic plate 602, then fix the clamp 606 with bolts. Pull the telescopic plate 602 upward to a suitable height, then tighten it using the knob 603 on the support frame 601, and pull the locking block 608 on the fourth rotating shaft 605 outward so that the locking block 608 is no longer locked between the locking block 608 and the groove on the rotating frame 604. At this time, the rotating frame 604 can be rotated at a certain angle through the fourth rotating shaft 605 so that the nozzle of the welding gun 7 is aligned with the connection between the corrugated pipe and the end pipe. Then release the locking block 608, and the locking block 608 will re-engage with the groove on the rotating frame 604 under the reset action of the second spring 607. This completes the installation of the welding gun 7 and the adjustment of the angle, avoiding the problem of difficult operation due to the small operating space during manual welding, and improving welding efficiency.

[0039] In use, the height of the clamp on the operating table 1 is adjusted according to the radius of the welded compensator. The first motors 205 on the two mounting brackets 201 drive the two first lead screws 203 to rotate, and then the first lead screws 203 drive the slide plate 204 to slide up and down along the first guide rod 202, thereby effectively adjusting the height of the clamp on the slide plate 204 and ensuring that the center points of the bellows and the end pipe are on the same straight line, which is highly flexible. Then, the bellows and the end pipe are respectively put on the two rotating sleeves 402. First, the second motor 414 on the back of the mounting plate 302 drives the rotating rod 401 at the driving end to rotate counterclockwise, and then the rotating rod 401 drives the second lead screw 403 at the end to rotate. At this time, the second lead screw 403 rotates. 3. A counterclockwise rotational force is applied to the drive ring 404. Since the drive ring 404 is connected to the rotating sleeve 402 via the contact plate 412, a counterclockwise rotational force is transmitted to the rotating sleeve 402. The rotating sleeve 402 drives the end limit block 505 to rotate. However, when there is a counterclockwise rotational force on the limit block 505, the limit block 505 meshes with the inner ratchet 503 inside the mounting base 501, thus blocking the rotation of the rotating sleeve 402 and the limit block 505. At this time, relative rotation occurs between the rotating rod 401 and the rotating sleeve 402. The rotating rod 401 rotates counterclockwise inside the rotating sleeve 402. Since the drive ring 404 is threadedly connected to the second lead screw 403, and... At this time, the drive ring 404 cannot rotate counterclockwise, thus driving the drive ring 404 to move towards the second motor 414. During the movement of the drive ring 404, the first rotating bar 407 and the second rotating bar 410 rotate via the first rotating shaft 406 on the first mounting block 405 and the second rotating shaft 409 on the second mounting block 408, respectively. At this time, the included angle between the first rotating bar 407 at the end of the rotating sleeve 402 and the second rotating bar 410 on the drive ring 404 gradually decreases. Simultaneously, the first rotating bar 407 at the other end of the rotating sleeve 402 rotates towards the second motor 414. Since the top ends of both the first rotating bar 407 and the second rotating bar 410 rotate via the third rotating shaft 411 and the contact plate 412, the drive ring 407 rotates towards the second motor 414. Furthermore, during the process of the first rotating bar 407 and the second rotating bar 410 driving the contact plate 412 to rotate towards the second motor 414, the contact plate 412 is kept parallel to the rotating sleeve 402 until the rubber pads 413 on the four contact plates 412 are in close contact with the inner wall of the bellows, thus completing the fixation of the bellows. The fixation is strong and the rubber pads 413 increase the friction between the bellows and the inner wall of the bellows. At the same time, the same operation is repeated on the end tube, so that the four contact plates 412 on the other end are pressed against the inner wall of the end tube. At this time, the bellows and the end tube are effectively fixed, improving stability and preventing the bellows or end tube from falling off the operating table 1 during the welding process. The operation is simple.

[0040] After the installation of the bellows and end pipe is completed, the telescopic ends of the hydraulic rods 304 on the two support plates 303 extend outwards simultaneously. Then, the hydraulic rods 304 drive the mounting plate 302 to slide along the second guide rod 301 through the connecting plate 305 at the end. At this time, the mounting plate 302 drives the two symmetrical rotating sleeves 402 to move towards the middle at the same time, thereby driving the bellows and end pipe to move towards the middle at the same time until the pipe openings of the bellows and end pipe are aligned and abut against each other. At this time, the bellows and end pipe can be welded. The operation is simple and avoids the problem of operators having to align the bellows and end pipes during the welding process, thus improving the welding efficiency.

[0041] After the installation of the corrugated pipe and end pipe is completed, the welding gun 7 is installed. Simply clamp the welding gun 7 onto the clamp 606 at the top of the telescopic plate 602, then fix the clamp 606 with bolts. Pull the telescopic plate 602 upward to a suitable height, then tighten it by the knob 603 on the support frame 601, and pull the locking block 608 on the fourth rotating shaft 605 outward so that the locking block 608 is no longer engaged with the groove on the rotating frame 604. At this time, the rotating frame 604 can be rotated by a certain angle through the fourth rotating shaft 605 so that the nozzle of the welding gun 7 is aligned with the connection between the corrugated pipe and the end pipe. Then release the locking block 608. Under the reset action of the second spring 607, the locking block 608 is re-engaged with the groove on the rotating frame 604. At this time, the installation of the welding gun 7 and the angle adjustment are completed, avoiding the problem of difficult operation due to the small operating space during manual welding, and improving welding efficiency.

[0042] During the welding process at the connection between the bellows and the end pipe, the welding angle needs to be adjusted by rotation. At this time, the second motors 414 on the back of the two mounting plates 302 drive the two rotating rods 401 to rotate clockwise. The rotating rods 401 then exert a clockwise force on the second lead screw 403 and the drive ring 404 at the end. The drive ring 404, through the contact plate 412, exerts a clockwise force on the rotating sleeve 402. Since the ratchet 503 does not obstruct the rotation of the limiting block 505 in the clockwise direction, the limiting block 505 slides inward into the rotating sleeve 402. When the first spring 504 is compressed, the friction between the drive ring 404 and the second lead screw 403 is greater than the friction between the limit block 505 and the inner ratchet 503. At the same time, the end of the rotating sleeve 402 is rotatably connected to the mounting base 501 through the bearing 502. Consequently, the rotating rod 401 drives the rotating sleeve 402 and the bellows to rotate clockwise. The end tube at the other end of the operating table 1 also rotates clockwise. This effectively rotates the bellows and end tube during the welding process, making it easy to perform 360-degree welding at the connection between the bellows and end tube. The operation is simple and highly flexible.
