Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically relates to a metal product welding equipment with multi-angle functions. Background Art

[0002] In modern industrial production, metal products are widely used. From mechanical manufacturing, automotive industry to aerospace and other fields, welding, as a key process in metal processing, its quality and efficiency directly affect the performance of products and production benefits.

[0003] However, the current traditional welding equipment clamps metal pipes through a three-jaw chuck. For large-diameter metal pipes, the existing fixtures cannot be effectively adapted, resulting in insecure clamping. During the welding process, it is easy to shake, seriously affecting the quality of the weld seam and increasing the probability of welding defects. When welding two long metal pipes into a metal pipeline, due to the lack of reliable support and fixing methods, the pipe body is prone to bending deformation under the action of gravity, which not only affects the welding accuracy but also may cause the size deviation of the welded metal product to exceed the standard range, reducing the qualified rate of the product.

[0004] When welding a metal branch pipe on a metal main pipe, the feeding and positioning of the metal branch pipe usually adopt the method of manual preliminary positioning and then temporary fixing by spot welding. This not only increases additional processes and time costs, but also the heat generated during spot welding is likely to change the material properties of the metal branch pipe, affecting product quality. In addition, the consistency of manual positioning is poor, and it is difficult to ensure that the position accuracy of each feeding is the same, resulting in unstable welding quality and further affecting production efficiency and the overall quality of the product.

Detailed implementation mode

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0035] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 shown, a metal product welding device with multi-angle functions according to the present invention includes a bottom plate 1, two traveling structures 2 provided on the bottom plate 1, a welding structure 3 provided on one of the traveling structures 2, an adjusting structure 4 provided on the bottom plate 1, a clamping structure 5 provided on the adjusting structure 4, and a fixing structure 6 provided on the other traveling structure 2;

[0036] The two mounting seats 403 of the adjustment structure 4 are each provided with a clamping structure 5, and the clamping structure 5 includes a gear ring 501 and a driving groove 502. The mounting seat 403 is rotatably connected with the gear ring 501, and three driving grooves 502 are arranged in a circumferential array on the gear ring 501. A clamping rod 503 is slidably connected inside the driving groove 502, and a clamping roller 504 is fixedly connected to the clamping rod 503. Three first guide grooves 505 are arranged in a circumferential array on the mounting seat 403. A connecting shaft 506 is rotatably connected to the mounting seat 403, and the end of the connecting shaft 506 is fixedly connected to the The mounting base 403 is connected to a gear 507, which meshes with the gear ring 501. A third motor 508 is fixedly connected to the mounting base 403. The output end of the third motor 508 is fixedly connected to the connecting shaft 506. When two metal main pipes 7 are welded into one metal main pipe 7, the metal main pipe 7 is placed near the clamping roller 504 and the third motor 508 is started. The third motor 508 drives the connecting shaft 506 to rotate, and the gear 507 at the end of the connecting shaft 506 rotates accordingly. The gear ring 501 meshed with the gear 507 starts to rotate, and the driving groove 502 on the gear ring 501 drives the clamping rod 506 to rotate. 3 slides in the first guide groove 505, so that the clamping roller 504 at the end of the clamping rod 503 moves toward the metal main pipe 7 until the metal main pipe 7 is clamped. The mounting seat 403 is fixedly connected to a plurality of connecting blocks 509, and the connecting blocks 509 are fixedly connected to the first hydraulic rod 510. The telescopic end of the first hydraulic rod 510 is fixedly connected to a connecting plate 511. The connecting plate 511 is provided with three second guide grooves 512 in a circumferential array. During the movement of the clamping rod 503, the guide wheel 513 rolls in the second guide groove 512 to ensure the smooth movement of the clamping rod 503. The end of 503 is rotatably connected to a guide wheel 513 with an "I"-shaped cross-section, and the guide wheel 513 is rollingly connected to the second guide groove 512; in addition, by controlling the extension and contraction of the first hydraulic rod 510, the position of the clamping roller 504 can be fine-tuned to better adapt to metal main pipes 7 of different lengths. At the same time, the position of the clamping roller 504 can be adjusted. When loading large-diameter metal pipes, the extended length of the clamping roller 504 is first reduced to reduce the difficulty of loading large-diameter metal pipes. After loading long metal pipes, the extended length of the clamping roller 504 can be increased as much as possible to improve the stability of clamping and supporting the long metal pipes.

[0037] Specifically, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8As shown, the adjustment structure 4 includes a linear motor 401 and a slide table 402 slidably connected to the linear motor 401. A linear motor 401 is fixedly connected to the base plate 1, and a mounting seat 403 is provided on each of the base plate 1 and the slide table 402. To adjust the distance between the clamping structures 5 to adapt to metal main pipes 7 of different lengths, start the linear motor 401. The linear motor 401 drives the slide table 402 to slide on its guide rail, thereby changing the distance between the two mounting seats 403. A plug table 404 in the shape of a frustum of a cone is rotatably connected to the mounting seat 403. At the same time, the frustum shape design of the plug table 404 makes the clamping of a single metal main pipe 7 more stable and suitable for fixing metal main pipes 7 of different calibers. A second motor 405 is fixedly connected to the mounting seat 403, and the output end of the second motor 405 is fixedly connected to the second motor 405. A metal main pipe 7 is inserted into the plug table 404, and three pinch rollers 504 clamp the metal main pipe 7. When it is necessary to adjust the angle of the metal main pipe 7, start the second motor 405. The output end of the second motor 405 drives the plug table 404 to rotate, and the metal main pipe 7 inserted into the plug table 404 rotates accordingly, realizing angle adjustment and facilitating subsequent welding operations.

[0038] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7As shown, the walking structure 2 includes a bearing block 201 and a screw rod 202. Four bearing blocks 201 are fixedly connected to the bottom plate 1. A screw rod 202 is rotatably connected between two opposite bearing blocks 201. A threaded seat 203 is threadedly connected to the screw rod 202. A walking platform 204 is fixedly connected to the threaded seat 203. When the screw rod 202 rotates, the threaded seat 203 threadedly connected to it will move along the axial direction of the screw rod 202, and the walking platform 204 fixed to the threaded seat 203 will move accordingly. A sliding sleeve 205 is fixedly connected to the bottom end of the walking platform 204. Four slide rails 206 are fixedly connected to the bottom plate 1. The sliding sleeve 205 is slidably connected to the slide rails 206. The sliding sleeve 205 at the bottom end of the walking platform 204 slides on the slide rails 206 to ensure the smooth movement of the walking platform 204. Two fixed seats 207 are fixedly connected to the bottom plate 1. A first motor 208 is fixedly connected to the fixed seat 207. A first pulley 209 is fixedly connected to the output end of the first motor 208. A second pulley 210 is fixedly connected to the end of the screw rod 202. The first pulley 209 and the second pulley 210 are driven by a belt. When the first motor 208 is started, its output end drives the first pulley 209 to rotate, and the second pulley 210 is driven to rotate through belt drive, thereby driving the screw rod 202 to rotate. The walking structure 2 is mainly used to adjust the positions of the welding structure 3 and the fixing structure 6 so that the welding head and the metal component to be welded can be in a suitable relative position;

[0039] The welding structure 3 includes a rotating base 301 and a base 302. A rotating base 301 is fixedly connected to one of the walking platforms 204. The base 302 is rotatably connected to the rotating base 301. A large arm 303 is rotatably connected to the base 302. A small arm 304 is rotatably connected to the large arm 303. A wrist rotation joint 305 is rotatably connected to the small arm 304. A wrist pitching joint 306 is rotatably connected to the wrist rotation joint 305. A wrist yaw joint 307 is rotatably connected to the wrist pitching joint 306. A laser welding head 308 is installed on the wrist yaw joint 307. A weld tracking sensor 309 is installed on the wrist yaw joint 307. During welding, when in use, according to the position of the metal component to be welded and the welding requirements, first rotate the rotating base 301 to adjust the orientation of the base 302. Then, by controlling the rotation of the large arm 303 and the small arm 304, the laser welding head 308 is roughly aligned with the welding position. Then, further finely adjust the wrist rotation joint 305, the wrist pitching joint 306 and the wrist yaw joint 307 to precisely adjust the angle of the laser welding head 308. During the welding process, the weld tracking sensor 309 real-time monitors the weld position. If there is a deviation, it will feedback in time and adjust the posture of the welding structure 3 to ensure that the laser welding head 308 always welds along the weld to ensure the welding quality;

[0040] Specifically, asFigure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, a fixing structure 6 is provided on another walking platform 204. The fixing structure 6 includes a loading rack 601 and a lifting plate 602 slidably connected to the loading rack 601. The loading rack 601 is fixedly connected to the walking platform 204. A second hydraulic rod 603 is fixedly connected to the loading rack 601. The telescopic end of the second hydraulic rod 603 is fixedly connected to the lifting plate 602. A sliding plate 604 is slidably connected to the lifting plate 602. A positioning platform 607 in the shape of a frustum of a cone is fixedly connected to the sliding plate 604. A metal branch pipe 8 is inserted into the outside of the positioning platform 607. A sliding frame 609 with a "ji" - shaped cross - section is slidably connected to the sliding plate 604. Two clamping blocks 610 are slidably connected to the sliding frame 609. The clamping blocks 610 are in contact with the flange of the metal branch pipe 8. The cross - section of the end of the clamping block 610 is a trapezoidal structure, and the end of the clamping block 610 is arc - shaped; A fixing plate 605 is fixedly connected to the sliding plate 604. A third hydraulic rod 606 is fixedly connected to the bottom end of the lifting plate 602. The telescopic end of the third hydraulic rod 606 is fixedly connected to the fixing plate 605. A fourth hydraulic rod 608 is fixedly connected to the sliding plate 604. The telescopic end of the fourth hydraulic rod 608 is fixedly connected to the sliding frame 609;Two T-shaped slide bars 611 are fixedly connected to each clamping block 610. The slide bars 611 are slidably connected to the slide carriage 609. A tension spring 612 is fixedly connected between the slide bars 611 and the slide carriage 609. First, insert the metal branch pipe 8 onto the positioning table 607. During insertion, since the end of the clamping block 610 has a trapezoidal cross-section, the flange of the metal branch pipe 8 will pass over the clamping block 610. The clamping block 610 slides along the slide bar 611. After the tension spring 612 extends and passes over the clamping block 610, the tension spring 612 resets and engages with the positioning table 607. At this time, start the fourth hydraulic rod 608. The telescopic end of the fourth hydraulic rod 608 pushes the slide carriage 609 upward. The clamping block 610 on the slide carriage 609 approaches the flange of the metal branch pipe 8 until the clamping block 610 abuts against and clamps the bottom surface of the flange. The slide bar 611 slides within the slide carriage 609, and the tension spring 612 provides a certain clamping force. According to the welding requirements, start the second hydraulic rod 603 to adjust the height of the lifting plate 602. Then, use the third hydraulic rod 606 to push the fixed plate 605, so that the slide plate 604 drives the metal branch pipe 8 to move to a suitable position for welding with the metal main pipe 7. During welding, since the slide plate 604 may cause obstruction, after welding the unobstructed part, the metal branch pipe 8 is already fixed to the metal main pipe 7. At this time, first start the second hydraulic rod 603. The second hydraulic rod 603 extends to drive the lifting plate 602 to rise, and then retract the fourth hydraulic rod 608, so that the positioning table 607 disengages from the metal branch pipe 8. Then, the fourth hydraulic rod 608 can be further retracted, which drives the slide carriage 609 to move downward. The downward movement of the slide carriage 609 drives the clamping block 610 to move downward. At this time, start the third hydraulic rod 606. The third hydraulic rod 606 retracts, driving the slide plate 604 to slide, and then driving the slide carriage 609 to slide. Since the end of the clamping block 610 has an arc-shaped structure, when the clamping block 610 slides back and forth with the slide carriage 609, it will drive the slide bar 611 to slide. The tension spring 612 extends and then resets, and the clamping block 610 no longer clamps the metal branch pipe 8. Then, transfer the loading rack 601 through the traveling structure 2 for the next loading. At this time, use the welding structure 3 to weld the remaining welds.;

[0041] When the present invention is in use, first, when welding two metal main pipes 7 into one metal main pipe 7, place the metal main pipe 7 near the pinch roller 504, start the third motor 508, the third motor 508 drives the connecting shaft 506 to rotate, and the gear 507 at the end of the connecting shaft 506 rotates accordingly. The toothed ring 501 meshing with the gear 507 starts to rotate, and the driving groove 502 on the toothed ring 501 drives the clamping rod 503 to slide in the first guiding groove 505, so that the pinch roller 504 at the end of the clamping rod 503 moves towards the metal main pipe 7 until the metal main pipe 7 is clamped. During the movement of the clamping rod 503, the guiding wheel 513 rolls in the second guiding groove 512 to ensure the smoothness of the movement of the clamping rod 503. In addition, by controlling the telescopic movement of the first hydraulic rod 510, the position of the pinch roller 504 can be finely adjusted to better adapt to metal main pipes 7 of different lengths. At the same time, the position of the pinch roller 504 can be adjusted. When feeding a large-diameter metal pipe, first reduce the extended length of the pinch roller 504 to reduce the feeding difficulty of the large-diameter metal pipe. After feeding a long metal pipe, the extended length of the pinch roller 504 can be increased as much as possible to improve the stability of clamping and supporting the long metal pipe;

[0042] Then, during use, if it is necessary to adjust the distance between the clamping structures 5 to adapt to metal main pipes 7 of different lengths, start the linear motor 401. The linear motor 401 drives the slide table 402 to slide on its guide rail, thereby changing the distance between the two mounting seats 403. At the same time, the frustum-shaped design of the plug table 404 makes the clamping of a single metal main pipe 7 more stable and applicable to fixing metal main pipes 7 of different diameters. The applicability of the device is high. When it is necessary to adjust the angle of the metal main pipe 7, start the second motor 405. The output end of the second motor 405 drives the plug table 404 to rotate, and the metal main pipe 7 inserted on the plug table 404 rotates accordingly to achieve angle adjustment, facilitating subsequent welding operations;

[0043] Secondly, during use, start the first motor 208, the output end of which drives the first pulley 209 to rotate. Through belt transmission, the second pulley 210 rotates, thereby driving the screw 202 to rotate. When the screw 202 rotates, the threaded seat 203 threadedly connected to it will move along the axial direction of the screw 202, and the walking platform 204 fixed on the threaded seat 203 will move accordingly. The sliding sleeve 205 at the bottom end of the walking platform 204 slides on the slide rail 206 to ensure the smooth movement of the walking platform 204. The walking structure 2 is mainly used to adjust the positions of the welding structure 3 and the fixing structure 6 so that the welding head and the metal component to be welded can be in a suitable relative position. During welding, during use, according to the position and welding requirements of the metal component to be welded, first rotate the turntable 301 to adjust the orientation of the base 302. Then, by controlling the rotation of the boom 303 and the forearm 304, the laser welding head 308 is roughly aligned with the welding position. Then, further finely adjust the wrist rotation joint 305, the wrist pitching joint 306, and the wrist yaw joint 307 to precisely adjust the angle of the laser welding head 308. During the welding process, the weld tracking sensor 309 monitors the weld position in real time. If there is a deviation, it will promptly feedback and adjust the posture of the welding structure 3 to ensure that the laser welding head 308 always welds along the weld, guaranteeing the welding quality;

[0044] Finally, first insert the metal branch pipe 8 on the positioning table 607. When inserting, since the cross-section of the end of the clamping block 610 is a trapezoidal structure, the flange of the metal branch pipe 8 will pass over the clamping block 610. The clamping block 610 slides with the sliding rod 611. After the tension spring 612 extends and passes over the clamping block 610, the tension spring 612 resets and is inserted with the positioning table 607. At this time, start the fourth hydraulic rod 608. The telescopic end of the fourth hydraulic rod 608 pushes the carriage 609 to move upward. The clamping block 610 on the carriage 609 then approaches the flange of the metal branch pipe 8 until the clamping block 610 abuts and clamps the bottom surface of the flange. The sliding rod 611 slides in the carriage 609, and the tension spring 612 provides a certain clamping force. According to the welding requirements, start the second hydraulic rod 603 to adjust the height of the lifting plate 602, and then push the fixing plate 605 through the third hydraulic rod 606, so that the sliding plate 604 drives the metal branch pipe 8 to move to a suitable position for welding with the metal main pipe 7. During welding, since the sliding plate 604 may cause occlusion, after welding the unoccluded part, the metal branch pipe 8 is already fixed on the metal main pipe 7. At this time, first start the second hydraulic rod 603. The second hydraulic rod 603 extends to drive the lifting plate 602 to rise, and then contract the fourth hydraulic rod 608, so that the positioning table 607 is separated from the metal branch pipe 8. Then the fourth hydraulic rod 608 can continue to contract, thereby driving the carriage 609 to move downward. The downward movement of the carriage 609 drives the clamping block 610 to move downward. At this time, start the third hydraulic rod 606 again. The third hydraulic rod 606 contracts, driving the sliding plate 604 to slide, and then driving the carriage 609 to slide. Since the end of the clamping block 610 is an arc-shaped structure, when the clamping block 610 slides back and forth with the carriage 609, it will drive the sliding rod 611 to slide. The tension spring 612 extends and then resets, and the clamping block 610 no longer clamps the metal branch pipe 8. Then transfer the loading rack 601 through the traveling structure 2 for the next loading. At this time, weld the remaining welds through the welding structure 3.
