Description

Technical Field

[0001] The invention relates to the technical field of steel structure splicing and welding, in particular to a welding device for splicing multiple steel structures. Background Art

[0002] Welding of multiple steel structures usually refers to connecting different types of steel structures such as main beams, lining rods, support columns, trusses, etc. by welding to form an integral load-bearing structure. The welding device for multiple steel structures is an integrated equipment system, usually including a variety of clamps, positioning devices and welding equipment, which are used to fix and weld steel structures of different shapes and sizes to ensure the accuracy and consistency of the welding process.

[0003] After searching, the Chinese patent "A welding method for prefabricated steel structure bridge construction" authorization announcement number "CN117324870B" clamps the lining rod through the clamping rod on the lining rod positioning mechanism, and then adjusts the placement position and placement angle of the lining rod through the lining rod positioning mechanism, and presses it down on the main beam for welding. It can automatically adjust the position and angle according to the placement of the lining rod, and has strong applicability.

[0004] In the above application, since the steel structure lining rod has a certain weight and the contact area between the clamp rod and the lining rod is limited, it is easy for the lining rod positioning mechanism to find it difficult to stably clamp the lining rod. The lining rod positioning mechanism hoists the lining rod to move the position and adjust the angle, which easily causes the clamped lining rod to be placed on the main beam and cause displacement, thereby reducing the accuracy of the splicing of the lining rod and the main beam, thereby reducing the welding effect of various steel structures. Summary of the invention

[0005] Based on this, it is necessary to provide a welding device for splicing various steel structures to address the problem of easy displacement of the clamping lining rod placed on the main beam, thereby reducing the precision of splicing the lining rod and the main beam.

[0036] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the clamping assembly 51 also includes a scraper 518 fixedly connected to one side of the guide block 517, a collecting groove 519 is opened on one side of the guide block 517, and two arc blocks 5124 are fixedly connected to one side of the guide block 517; the inner walls of the first clamping frame 513 and the second clamping frame 514 are fixedly connected to the first spring 5122 and the second spring 5121, the other end of the first spring 5122 is fixedly connected to one side of the locking block 5120, and the other end of the second spring 5121 is fixedly connected to the end of the stop block 516, and the inner wall of the stop block 516 is fixedly connected to the third spring 5123, and the other end of the third spring 5123 is fixedly connected to the One end is fixedly connected to one side of the guide block 517, the inner wall of the mounting frame 511 is fixedly connected with a first electric push rod 522, the telescopic end of the first electric push rod 522 is fixedly connected with a driving frame 521, the lower end of the surface of the active frame 523 is slidably connected to the surface of the driving frame 521, the inner wall of the movable frame 4 is fixedly connected with a first motor 529, the output shaft of the first motor 529 is fixedly connected with a driving disk 528, the lower end of the surface of the slide 512 is slidably connected to the inner wall of the driving disk 528, the upper end of the surface of the mounting frame 511 is fixedly connected with a guide frame 5210, and the lower end of the surface of the guide frame 5210 is rollingly connected with a ball 5211.

[0037] The driving frame 521 includes a driving frame and a fixed block, which are fixedly connected to each other. The telescopic end of the first electric push rod 522 is fixedly connected to the bottom of the fixed block. The surfaces of the driving frame and the locking block 5120 are both isosceles trapezoidal. The lower end of the surface of the active frame 523 is slidably connected to the surface of the driving frame. Two driving holes are provided at the top of the driving disk 528. The lower end of the surface of the slide 512 is slidably connected to the inner wall of the driving hole. The surface of the guide block 517 is in the shape of a right-angled trapezoid.

[0038] In the initial state, the two first clamping frames 513 are away from each other.

[0039] When multiple steel structures need to be spliced, the longer I-beam is placed on the driving mechanism 2, and the shorter I-beam is pushed to the inner side of the guide frame 5210, so that the I-beam will not have a large offset during the pushing process, and then the I-beam is pushed to the top of the installation frame 511, and the first electric push rod 522 is manually opened, and the telescopic end of the first electric push rod 522 moves downward to drive the driving frame 521 to move downward, and the driving frame 521 moves downward to pull the two sets of active frames 523 closer to each other, and the active frame 523 moves to drive the active block 524 and the first clamping frame 513 to move, so that the two first clamping frames 513 are closer to each other, and the first clamping frame 513 moves to drive the guide block 517 with a right-angled trapezoidal surface to move toward the direction of the shorter I-beam;

[0040] Because the inclined surface of the guide block 517 faces the shorter I-beam surface, the guide block 517 contacts the shorter I-beam surface during movement, so that the guide block 517 is longitudinally squeezed, and then the guide block 517 and the stopper 516 move longitudinally and squeeze the second spring 5121, and the surface of the I-beam contacts the surface of the arc block 5124, so that the guide block 517 and the stopper 516 smoothly enter the I-beam groove, and avoid the scraper 518 from directly contacting the I-beam surface. At this time, the second spring 5121 pushes the stopper 516, the guide block 517, and the scraper 518 to move longitudinally, so that the stopper 516 and the scraper 518 contact the inner wall of the I-beam groove. At this time, the first clamping frame 513 drives the stopper 516, the guide block 517, and the scraper 518 to continue to move, and the moving scraper 518 scrapes impurities on the inner wall of the I-beam groove, so that the scraped impurities fall into the collecting tank 519;

[0041] The first clamping frame 513 drives the moving block 515 to contact the I-beam groove, and the first clamping frame 513 continues to move toward the moving block 515 and contacts the side of the moving block 515, so that the moving block 515 drives the locking block 5120 to move in the first clamping frame 513, so that the inclined surface of the locking block 5120 pushes the two blocking blocks 516 away from each other, so that the two blocking blocks 516 stably contact the inner wall of the I-beam groove, and the first electric push rod 522 is automatically closed, so that the first clamping frame 513 locks the shorter I-beam;

[0042] The first motor 529 is manually turned on, and the output shaft of the first motor 529 rotates to drive the driving disk 528 to rotate. The second driving disk 528 rotates to drive the two slides 512 to move away from each other. The movement of the slide 512 drives the second clamping frame 514 to move into the longer I-beam groove. The stop block 516 and the shift block 515 on the second clamping frame 514 lock the longer I-beam according to the above process, so that the shorter I-beam can be stably spliced ​​at the longer I-beam. At this time, the welding robot 3 is manually turned on. After the welding process of the welding robot 3 is set by the CNC machine, the welding robot 3 performs welding operations on various I-beams.

[0043] like Figure 7 , Figure 8 As shown, the adjustment component 52 includes a cylinder 526 fixedly connected to the upper end of the inner wall of the installation frame 511, the top of the cylinder 526 is fixedly connected to the I-frame 525, the inner wall of the installation frame 511 is provided with four active frames 523, the inner wall of the active frame 523 is slidably connected with an active block 524, the surface of the first clamping frame 513 is rotatably connected to the upper end of the surface of the active block 524, the inner wall of the active block 524 is slidably connected to the surface of the I-frame 525, the upper end of the surface of the active block 524 is provided with annularly distributed thread grooves 5217, the surface of the first clamping frame 513 is threadedly connected to a first bolt 5218, and the surface of the first bolt 5218 is threadedly connected to the inner wall of one of the thread grooves 5217.

[0044] When the angle steel is clamped, the cylinder 526 is manually opened, and the top of the cylinder 526 moves upward to drive the I-shaped frame 525 to move upward. The I-shaped frame 525 moves upward to drive the four active blocks 524 to move upward in their respective active frames 523. After the active blocks 524 move upward to drive the first clamping frame 513 to move up to a suitable angle, the cylinder 526 is automatically closed. At this time, one of the first bolts 5218 is rotated to make the first bolt 5218 away from the corresponding thread groove 5217, and the lock of one of the first clamping frames 513 is released. The first clamping frame 513 is pushed to flip 90 degrees on the active block 524, and the first bolt 5218 is aligned with the appropriate thread groove 5217 and rotated to make the first bolt 5218 threaded in the appropriate thread groove 5217. The clamping frame 513 is locked on the active block 524. At this time, the first electric push rod 522 is manually opened. The telescopic end of the first electric push rod 522 moves downward through the driving frame 521, the active frame 523 and the active block 524 to drive the two first clamping frames 513 to approach each other, and clamp the two sides of the angle steel. The first clamping frame 513 flipped 90 degrees drives the guide block 517 to move toward the end of the angle steel, so that one of the moving guide blocks 517 contacts the side of the angle steel, pushes one of the guide blocks 517 to move upward and squeezes the third spring 5123, so that one of the guide blocks 517 moves smoothly to the end of the angle steel. At this time, the elastic force of the third spring 5123 pushes one of the guide blocks 517 to move downward and press against the end of the angle steel, and automatically closes the first electric push rod 522.

[0046] Before splicing various steel structures, push the limit block 5214 to move in a circle on the top of the movable frame 4. By observing the scale lines on the scale ring 5216, it can be known that the limit block 5214 has moved in a circle to an appropriate degree, and rotate the second bolt 5215 so that the second bolt 5215 rotates in the limit block 5214 and presses down on the top of the movable frame 4.

[0049] When the placement angle of the shorter I-beam is adjusted, the third electric push rod 63 is manually turned on, and the telescopic end of the third electric push rod 63 moves to drive the slider 61 and the long plate 62 to move, so that the long plate 62 is away from the rear end of the shorter I-beam. The third electric push rod 63 is manually closed and the second motor 527 is turned on. The output shaft of the second motor 527 rotates to drive the installation frame 511 to rotate. The rotation of the installation frame 511 drives the finger block 5212 and the clamped I-beam to move in a ring. The finger block 5212 moves to contact the side of the limit block 5214, and the second motor 527 is automatically closed, so that the I-beam moves in a ring to a suitable angle.

[0050] like Figure 2 As shown, two hydraulic cylinders 26 are fixedly connected to the lower end of the surface of the workbench 1, and the bottom ends of the hydraulic cylinders 26 are fixedly connected to a fixed frame 27. The lower end of the surface of the movable frame 4 is slidably connected to the inner wall of the fixed frame 27, and the inner wall of the fixed frame 27 is rotatably connected to one end of a screw rod 28. The lower end of the inner wall of the movable frame 4 is threadedly connected to the surface of the screw rod 28, and a fourth motor 29 is fixedly connected to one side of the fixed frame 27, and the output shaft of the fourth motor 29 is fixedly connected to one end of the screw rod 28.

[0051] The first motor 529 , the second motor 527 , the third motor 24 and the fourth motor 29 are all servo motors.

[0052] After welding is completed, the clamping state of the I-beam is released by the splicing mechanism 5, and the hydraulic cylinder 26 is manually opened. The bottom end of the hydraulic cylinder 26 moves downward to drive the fixed frame 27 and the movable frame 4, so that the splicing mechanism 5 is away from the I-beam. At this time, the hydraulic cylinder 26 is manually closed and the fourth motor 29 is turned on. The output shaft of the fourth motor 29 rotates to drive the screw rod 28 to rotate. The rotation of the screw rod 28 drives the movable frame 4 to move to a suitable position in the fixed frame 27. The fourth motor 29 is manually closed and the splicing mechanism 5 is driven by the hydraulic cylinder 26 to move up to a suitable height to clamp and weld the I-beam.

[0053] When in use, the longer I-beam is placed on the placement rack 23 with the adjusted position, and the driving disk 528 is rotated to move the slide 512 and the second clamping frame 514, so that the second clamping frame 514, the stop block 516 and the shifting block 515 are in contact with the longer I-beam groove, and the longer I-beam is locked, and the shorter I-beam is guided by the guide frame 5210 and pushed to the top of the installation frame 511, so that the rear end of the shorter I-beam is in contact with the long plate 62, and the pushing of the shorter I-beam is stopped, and the first electric push rod 522 is manually opened. The telescopic end of the first electric push rod 522 moves downward through the driving frame 521, the active frame 523, and the active block 524 to drive the two first clamping frames 513 to approach each other, so that the guide block 517 contacts the surface of the shorter I-beam during movement, and the surface of the I-beam contacts the surface of the arc block 5124, so that the guide block 517 and the stop block 515 are in contact with each other. The block 516 moves longitudinally and squeezes the second spring 5121 and smoothly enters the I-beam groove. The second spring 5121 pushes the block 516, the guide block 517, and the scraper 518 to move longitudinally, so that the block 516 and the scraper 518 contact the inner wall of the I-beam groove. The moving scraper 518 scrapes off the impurities on the inner wall of the I-beam groove. The first clamping frame 513 continues to move toward the direction close to the moving block 515 and contacts the side of the moving block 515, so that the other side of the moving block 515 contacts the I-beam groove, so that the moving block 515 drives the locking block 5120 to move and push the two blocks 516 away from each other, so that the two blocks 516 stably contact the inner wall of the I-beam groove, and the first electric push rod 522 is automatically closed, so that the first clamping frame 513 locks the shorter I-beam, and the welding robot 3 performs welding operations on the contact between the shorter I-beam and the longer I-beam.

[0054] It should be noted that the workbench 1, the bidirectional screw 21, the screw 28, the first electric push rod 522, the second electric push rod 25, the third electric push rod 63, the hydraulic cylinder 26, the pneumatic cylinder 526, the welding robot 3, the first motor 529, the second motor 527, the third motor 24 and the fourth motor 29 in the above description are all devices with relatively mature applications in the prior art, and the specific models can be selected according to actual needs. At the same time, the first electric push rod 522, the second electric push rod 25, the third electric push rod 63, the hydraulic cylinder 26, the pneumatic cylinder 526, the welding robot 3, the first motor 529, the second motor 527, the third motor 24 and the fourth motor 29 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.
