Description

Technical Field

[0001] This invention relates to the field of metal welding technology, and more specifically to an intelligent metal welding device for processing hardware products. Background Technology

[0002] Hardware products have played a vital role in human survival and development. With socio-economic development and the refinement of the division of labor, hardware products have become increasingly diverse and sophisticated. As the world's largest steel producer and most populous country, my country possesses the advantage of low raw material and labor costs for manufacturing hardware products. Metal welding equipment for hardware products is a crucial piece of equipment used for metal welding during the hardware manufacturing process.

[0003] In the process of hardware product processing, welding between pipe fittings is a major part of the work that needs to be welded. However, existing pipe welding equipment has some shortcomings in its use, as follows:

[0004] The current method of welding pipe fittings requires first cutting the weld joint at the welding location before welding. This cutting is done manually by workers or using machine tools, followed by welding with automated equipment. Using machine tools increases overall processing time and costs. Manually grinding the weld joint by workers doesn't allow for precise cutting based on the specific welding conditions, making it difficult to guarantee welding quality. Furthermore, after welding, the weld scar needs to be removed, making the welding process overly cumbersome and hindering the ability to quickly weld pipe fittings. Summary of the Invention

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. In the welding process of this invention, the two pipe fittings to be welded are first inserted into the inner sides of the positioning transmission assembly and the hydraulic assembly, respectively. Then, the first servo motor drives the transmission shaft to rotate, which in turn drives the two transmission gears to rotate. The meshing between the outer teeth of the transmission gears and the transmission teeth drives the positioning ring to rotate, which in turn drives the arc-shaped push groove to rotate and pushes the push rod to move. Under the positioning of the guide rod, the push rod moves inward, which in turn drives the push square rod and the clamping arc plate to move inward to fix the pipe fittings. Then, the first hydraulic cylinder injects hydraulic oil into the inner side of the telescopic sleeve through the transmission pipe, which pushes the limit ring and the telescopic tube to extend and retract, adjusts the position of the first guide rail and the second guide rail, and then adjusts the position of the cutting assembly and the welding gun assembly, so that the cutting assembly moves to the position where cutting is required. Then, according to the slope requirements of the weld joint of the pipe fittings, the second servo motor drives the threaded rod to rotate, and then... With the cutting positioning column positioned on the first connecting arc plate, the threaded pushing ring and the first connecting arc plate descend, which in turn drives the lifting ring to descend. This, in turn, drives the second rotary positioning assembly and the cutting blade body to rotate along the rotary positioning axis. Since the length of the transmission rotating rod is fixed and it can rotate relative to the first and second rotary positioning assemblies, the descending lifting ring can push the cutting blade body, changing the angle between the cutting blade body and the cutting positioning column. The second hydraulic cylinder then extends and retracts the first multi-stage hydraulic rod, adjusting the position of the cutting blade body. Power is then supplied to the first and second guide rails, causing the cutting assembly, welding gun assembly, and second connecting arc plate to rotate along the guide rails. The chip discharge groove cuts the weld joint of the pipe fitting, enabling the cutting of corresponding weld joints according to different pipe fitting welding needs. This rapid cutting of pipe fitting weld joints ensures efficient pipe fitting welding.

[0017] 2. After the weld joint cutting is completed, the present invention adjusts the fixed position of the pipe fittings through the clamping assembly to ensure that the spacing between the pipe fittings meets the welding requirements. Then, the position of the welding gun assembly is adjusted through the hydraulic assembly. Subsequently, the second hydraulic cylinder drives the first multi-stage hydraulic rod to retract, causing the cutting assembly to return to its original position. Then, the second multi-stage hydraulic rod pushes the welding gun body upward, so that the welding needle is in the welding position. Then, by energizing the first guide rail and the second guide rail, the cutting assembly, the welding gun assembly, and the second connecting arc plate rotate along the first guide rail and the second guide rail. Finally, the pipe fittings are welded by the welding needle, realizing rapid welding of pipelines. In the process of welding hardware pipe fittings, it is not necessary to complete the welding work through multiple machines, thereby indirectly improving the welding efficiency of hardware pipe fittings.

[0018] 3. After welding is completed, the present invention uses a second servo motor to adjust the angle between the cutting blade body and the cutting positioning post, so that the angle between the cutting blade body and the cutting positioning post is 90 degrees. Since the radius of the rounded corner of the cutting blade body near the cutting positioning post is the same as the thickness of the cutting blade body, and the distance between the center of the rotation positioning shaft and the bottom of the cutting positioning post is the same as the radius of the rounded corner of the cutting blade body, the bottom of the cutting blade body and the bottom of the cutting positioning post are on the same plane. Then, by energizing the first guide rail and the second guide rail, the cutting assembly, the welding gun assembly and the second connecting arc plate rotate along the first guide rail and the second guide rail, so that the chip discharge groove completes the cutting of the weld scar, ensuring the aesthetic appearance of the hardware fittings.

A second guide rail 507 is fixedly connected to the inner side of the first guide rail 506. After the weld joint cutting is completed, the clamping assembly 4 adjusts the fixed position of the pipes so that the spacing between the pipes meets the welding requirements. Then, the hydraulic assembly 5 adjusts the position of the welding torch assembly 7. The cutting assembly 6 is then moved back to its original position by the operation of the second hydraulic cylinder 602, which in turn drives the first multi-stage hydraulic rod 603 to retract. Then, the second multi-stage hydraulic rod 703 pushes the welding gun body 704 to rise, so that the welding needle 705 is in the welding position. Then, by energizing the first guide rail 506 and the second guide rail 507, the cutting assembly 6, the welding gun assembly 7, and the second connecting arc plate 8 rotate along the first guide rail 506 and the second guide rail 507. Then, the welding needle 705 welds the pipe fittings, realizing rapid welding of the pipeline. In the process of welding hardware pipe fittings, it is not necessary to complete the welding work through multiple machines, thereby indirectly improving the welding efficiency of hardware pipe fittings.

[0036] In a preferred embodiment, the cutting assembly 6 includes a first positioning slider 601, a second hydraulic cylinder 602 fixedly connected to the bottom of the first positioning slider 601, a first multi-stage hydraulic rod 603 fixedly connected to the bottom of the second hydraulic cylinder 602, a first fixed square plate 604 fixedly connected to the bottom of the first multi-stage hydraulic rod 603, a second servo motor 6017 fixedly connected to the bottom of the first fixed square plate 604, a threaded rod 607 fixedly connected to the output shaft of the second servo motor 6017, a cutting positioning post 606 fixedly connected to the bottom of the first fixed square plate 604, a threaded push ring 6016 movably sleeved on the outer side of the threaded rod 607, and first connecting arc-shaped plates 6015 fixedly connected to both sides of the threaded push ring 6016.

A transmission rotary rod 6013 is movably connected to the outer side of the first rotary positioning assembly 6012. A positioning bearing 608 is fixedly connected to the bottom of the outer side of the threaded rod 607. A second rotary positioning assembly 6014 is movably connected to the bottom of the transmission rotary rod 6013. A cutting blade body 6010 is fixedly connected to the bottom of the second rotary positioning assembly 6014. A chip discharge groove 6011 is opened on the front side of the cutting blade body 6010. A rotary positioning shaft 609 is movably sleeved on the bottom of the front side of the chip discharge groove 6011. The front and back sides of the rotary positioning shaft 609 are fixedly connected to the cutting positioning post 606.During welding, the two pipe fittings to be welded are first inserted into the inner sides of the positioning transmission assembly 3 and the hydraulic assembly 5, respectively. Then, the first servo motor 304 drives the transmission shaft 305 to rotate, which in turn drives the two transmission gears 306 to rotate. The meshing between the outer teeth of the transmission gears 306 and the transmission teeth 402 drives the positioning ring 401 to rotate, which in turn drives the arc-shaped push groove 403 to rotate, thus pushing the push rod 404 to move. Under the positioning of the guide rod 407, the push rod 404 moves inward, which in turn drives the push square rod 405 and the clamp. The arc-holding plate 406 moves inward to fix the pipe fitting. Then, hydraulic oil is injected into the inside of the telescopic sleeve 503 through the transmission pipe 502 via the first hydraulic cylinder 501, pushing the limit ring 505 and the telescopic tube 504 to extend and retract, adjusting the positions of the first guide rail 506 and the second guide rail 507, and then adjusting the positions of the cutting component 6 and the welding gun component 7, so that the cutting component 6 moves to the position where cutting is required. Then, according to the slope requirements of the weld joint of the pipe fitting, the second servo motor 6017 drives the threaded rod 607 to rotate, and then the cutting positioning post 606 moves towards the first... Positioned by the connecting arc plate 6015, the threaded pushing ring 6016 descends with the first connecting arc plate 6015, which in turn drives the lifting ring 605 to descend, thereby pushing the second rotary positioning assembly 6014 and the cutting blade body 6010 to rotate along the rotary positioning axis 609. Since the length of the transmission rotary rod 6013 is fixed, and the transmission rotary rod 6013 can rotate relative to the first rotary positioning assembly 6012 and the second rotary positioning assembly 6014, the descent of the lifting ring 605 can push the cutting blade body 6010, causing the cutting blade body 6010 to align with the cutting positioning post 6010. The angle between the two components changes, causing the first multi-stage hydraulic rod 603 to extend and retract via the operation of the second hydraulic cylinder 602. This, in turn, pushes and adjusts the position of the cutting blade body 6010. Then, by energizing the first guide rail 506 and the second guide rail 507, the cutting assembly 6, the welding gun assembly 7, and the second connecting arc plate 8 rotate along the first guide rail 506 and the second guide rail 507. The chip discharge groove 6011 cuts the weld joint of the pipe fitting, enabling the cutting of corresponding weld joints according to different pipe fitting welding needs. This allows for rapid cutting of pipe fitting weld joints, ensuring efficient pipe fitting welding.

[0037] In a preferred embodiment, the welding torch assembly 7 includes a second positioning slider 701, a third hydraulic cylinder 702 fixedly connected to the top of the second positioning slider 701, a second multi-stage hydraulic rod 703 fixedly connected to the top of the third hydraulic cylinder 702, a welding torch body 704 fixedly connected to the top of the second multi-stage hydraulic rod 703, and a welding needle 705 fixedly connected to the top of the welding torch body 704. After welding is completed, the angle between the cutting blade body 6010 and the cutting positioning post 606 is adjusted by the operation of the second servo motor 6017, so that the angle between the cutting blade body 6010 and the cutting positioning post 606 is ninety degrees, and because the cutting blade body 6010... The radius of the fillet near the cutting positioning post 606 is the same as the thickness of the cutting blade body 6010, and the distance between the center of the rotating positioning shaft 609 and the bottom of the cutting positioning post 606 is the same as the radius of the fillet of the cutting blade body 6010. At this time, the bottom of the cutting blade body 6010 and the bottom of the cutting positioning post 606 are on the same plane. Then, by energizing the first guide rail 506 and the second guide rail 507, the cutting assembly 6, the welding gun assembly 7, and the second connecting arc plate 8 are rotated along the first guide rail 506 and the second guide rail 507, so that the chip discharge groove 6011 completes the cutting of the weld scar, ensuring the aesthetic appearance of the hardware fittings.

[0038] In a preferred embodiment, the outer teeth of the transmission gear 306 mesh with the transmission teeth 402, the width of the arc-shaped push groove 403 is clearance-fitted with the diameter of the push rod 404, the width of the inner side of the limiting strip plate 408 is clearance-fitted with the diameter of the push rod 404, a guide hole is provided on the outer side of the push rod 404, and the diameter of the guide hole of the push rod 404 is clearance-fitted with the diameter of the guide rod 407.

[0039] In a preferred embodiment, the dimensions of the inner sidewall of the telescopic sleeve 503 are matched with the dimensions of the limiting ring 505, the dimensions of the opening on the other side of the telescopic sleeve 503 are matched with the cross-sectional dimensions of the telescopic tube 504, the cross-sectional dimensions of the first positioning slider 601 and the second positioning slider 701 are both tolerance matched with the cross-sectional dimensions of the first guide rail 506 and the second guide rail 507, and the top of the first positioning slider 601 and the bottom of the second positioning slider 701 are attached to the inner side of the telescopic tube 504.

[0040] In a preferred embodiment, the bottom of both sides of the cutting positioning post 606 is provided with a rotating groove, the width of the rotating groove of the cutting positioning post 606 is clearance-fitted with the width of the cutting blade body 6010, the top of the threaded push ring 6016 is provided with a threaded hole, the threaded hole at the top of the threaded push ring 6016 is engaged with the thread on the outer side of the threaded rod 607, and the sides of the cutting positioning post 606 are provided with arc-shaped grooves, the size of the arc-shaped groove of the cutting positioning post 606 is in dimensional tolerance with the first connecting arc-shaped plate 6015.

[0041] The working principle of this invention is as follows: During welding, the two pipe fittings to be welded are first inserted into the inner sides of the positioning transmission assembly 3 and the hydraulic assembly 5, respectively. Then, the first servo motor 304 drives the transmission shaft 305 to rotate, which in turn drives the two transmission gears 306 to rotate. The meshing between the outer teeth of the transmission gears 306 and the transmission teeth 402 drives the positioning ring 401 to rotate, which in turn drives the arc-shaped pushing groove 403 to rotate and pushes the pushing rod 404 to move. Under the positioning of the guide rod 407, the pushing rod 404 moves inward and then drives the pushing... The square rod 405 and the clamping arc plate 406 move inward to fix the pipe fitting. Then, hydraulic oil is injected into the inside of the telescopic sleeve 503 through the transmission pipe 502 via the first hydraulic cylinder 501, pushing the limit ring 505 and the telescopic tube 504 to extend and retract, adjusting the positions of the first guide rail 506 and the second guide rail 507, and then adjusting the positions of the cutting component 6 and the welding gun component 7, so that the cutting component 6 moves to the position where cutting is required. Then, according to the slope requirements of the weld joint of the pipe fitting, the second servo motor 6017 drives the threaded rod 607 to rotate, and then cuts the positioning post. Positioned by the first connecting arc plate 6015, the threaded pushing ring 6016 and the first connecting arc plate 6015 are pushed down, which in turn drives the lifting ring 605 down, thereby pushing the second rotary positioning assembly 6014 and the cutting blade body 6010 to rotate along the rotary positioning axis 609. Since the length of the transmission rotating rod 6013 is fixed and the transmission rotating rod 6013 can rotate relative to the first rotary positioning assembly 6012 and the second rotary positioning assembly 6014, the descent of the lifting ring 605 can push the cutting blade body 6010, so that the cutting blade body 6010 and the cutting positioning... The angle between the columns 606 changes, and the second hydraulic cylinder 602 works to extend and retract the first multi-stage hydraulic rod 603, which in turn pushes and adjusts the position of the cutting blade body 6010. Then, by energizing the first guide rail 506 and the second guide rail 507, the cutting assembly 6, the welding gun assembly 7, and the second connecting arc plate 8 rotate along the first guide rail 506 and the second guide rail 507. The chip discharge groove 6011 cuts the weld joint of the pipe fitting. It can cut the corresponding weld joint according to the different welding needs of different pipe fittings, and can quickly complete the cutting of the pipe fitting weld joint, ensuring the welding efficiency of the pipe fitting.

[0042] After the weld joint is cut, the clamping assembly 4 is used to adjust the fixed position of the pipe fittings so that the spacing between the pipe fittings meets the welding requirements. Then, the position of the welding gun assembly 7 is adjusted by the hydraulic assembly 5. Then, the second hydraulic cylinder 602 works to drive the first multi-stage hydraulic rod 603 to retract, so that the cutting assembly 6 returns to its original position. Then, the second multi-stage hydraulic rod 703 pushes the welding gun body 704 to rise so that the welding needle 705 is in the welding position. Then, by energizing the first guide rail 506 and the second guide rail 507, the cutting assembly 6, the welding gun assembly 7, and the second connecting arc plate 8 rotate along the first guide rail 506 and the second guide rail 507. Then, the pipe fittings are welded by the welding needle 705, realizing the rapid welding of the pipeline. In the process of welding hardware pipe fittings, it is not necessary to complete the welding work through the cooperation of multiple equipment, thereby indirectly improving the welding efficiency of hardware pipe fittings.

[0043] After welding is completed, the second servo motor 6017 drives and adjusts the angle between the cutting blade body 6010 and the cutting positioning post 606, so that the angle between the cutting blade body 6010 and the cutting positioning post 606 is 90 degrees. Since the radius of the rounded corner of the cutting blade body 6010 near the cutting positioning post 606 is the same as the thickness of the cutting blade body 6010, and the distance between the center of the rotating positioning shaft 609 and the bottom of the cutting positioning post 606 is the same as the radius of the rounded corner of the cutting blade body 6010, the bottom of the cutting blade body 6010 and the bottom of the cutting positioning post 606 are on the same plane. Then, by energizing the first guide rail 506 and the second guide rail 507, the cutting assembly 6, the welding gun assembly 7 and the second connecting arc plate 8 rotate along the first guide rail 506 and the second guide rail 507, so that the chip discharge groove 6011 completes the cutting of the weld scar, ensuring the aesthetic appearance of the hardware fittings.
