Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding shaping device and method for airfoil support blades. Background Technology

[0002] When welding airfoil blades, the blades are usually shaped by upper and lower molds before welding to ensure structural accuracy and welding quality. The upper and lower molds clamp the leading and trailing edges of the blades to fix key geometric parameters such as chord length and twist angle, preventing deformation caused by high temperature or external force during the welding process.

[0003] It should be noted that the key points of the welding process and the welding sequence are as follows: first, weld the tie rods or supporting structures to fix the overall shape of the blade, and then perform riveting or overlay welding for reinforcement. If laser welding is used, the laser focus and shielding gas need to be adjusted after clamping the mold to ensure uniform weld seam. When welding airfoil blades with a laser welding machine, the machine casing needs to maintain efficient heat dissipation to ensure continuous and safe welding. However, during welding operations, due to the complex construction site environment, the large number of materials and equipment on the welding site, and frequent personnel movement, accidental collisions or movement of the laser welding machine casing can easily cause materials or equipment to be too close to the machine casing, thus encroaching on the heat dissipation space of the casing and preventing the casing from effectively dissipating heat, resulting in interruption of airfoil blade welding or substandard welding quality. In addition, if the casing is knocked over, it will directly hit the ground, which can easily cause damage to the casing. Summary of the Invention

[0004] The purpose of this invention is to provide a welding and shaping device and method for airfoil support blades to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A welding and shaping device for airfoil support blades includes a welding host, on both sides of which are provided with multiple heat dissipation holes, and two cooling fans are installed inside the welding host. Universal wheels are movably installed at the four corners of the bottom side of the welding host.

[0007] It also includes an active opening device, which is installed on the welding host and is used to maintain the heat dissipation space of the welding host. The active opening device includes two heat dissipation blowing plates, which are respectively movably installed on both sides of the welding host. A mounting base is installed on the bottom side of the welding host. Pull-out brackets are movably installed on both sides of the mounting base. Linkage brackets are installed on both pull-out brackets. The two linkage brackets are respectively installed on the two heat dissipation blowing plates. Multiple flip-opening brackets are rotatably installed on both sides of the welding host. Support wheels are rotatably installed on both sides of the flip-opening brackets. The flip-opening brackets rotate to open the welding host to maintain the heat dissipation space of the welding host.

[0008] The welding host is equipped with a heat dissipation retention device, which is used to maintain the heat dissipation range of the welding host; the heat dissipation retention device includes four recovery covers, which are respectively installed on the inner walls of both sides of the welding host, and heat dissipation sealing plates are movably installed inside the recovery covers, which are used to seal the heat dissipation holes;

[0009] It also includes a side-tilting support device, which is installed on the bottom side of the welding host and is used to support the welding host. The side-tilting support device includes two active brackets, both of which are slidably installed on the bottom side of the welding host. The two active brackets are respectively inserted into the two pull-out brackets to restrict the two pull-out brackets and to support the welding host.

[0010] Furthermore, in a preferred embodiment of the present invention, the active spreading device further includes a plurality of mounting brackets, which are respectively mounted on both sides of the welding host, and a connecting central shaft is rotatably mounted on each of the plurality of mounting brackets, and the plurality of flip spreading frames are respectively mounted on the plurality of connecting central shafts;

[0011] A push lever is installed at one end of the connecting shaft, and four synchronous push frames are installed on the heat dissipation blow plate. The movement of the heat dissipation blow plate drives the push lever to rotate through the synchronous push frames, which in turn drives the flip-out support frame to rotate.

[0012] Furthermore, in a preferred embodiment of the present invention, two flipping slots are provided on the flipping support frame, and the connecting rotating shaft is rotatably installed in the two flipping slots;

[0013] A torsion spring is installed on the inner wall of the rotating groove, and the torsion spring is mounted on the connecting rotating shaft.

[0014] Furthermore, in a preferred embodiment of the present invention, a pull-back spring is installed on the pull-out bracket, and the pull-back spring is installed on the inner wall of the mounting base.

[0015] Furthermore, in a preferred embodiment of the present invention, the heat dissipation retaining device further includes a plurality of synchronous drive frames, which are respectively mounted on a plurality of heat dissipation sealing plates;

[0016] Rotating connecting rods are rotatably mounted on the inner walls of both sides of the welding host. Two synchronous drive shafts are rotatably mounted on the rotating connecting rods. The two synchronous drive shafts are respectively movably mounted in two synchronous drive frames located on the same side.

[0017] Furthermore, in a preferred embodiment of the present invention, two lifting rods are slidably installed on the top inner wall of the welding host, and an upward push shaft is installed on each of the two lifting rods. A wedge-shaped push plate is installed on each of the two heat dissipation blowing plates. The heat dissipation blowing plates drive the wedge-shaped push plates to move, thereby driving the upward push shaft to move.

[0018] The lifting rod is equipped with a lifting shaft, and the movement of the lifting rod drives the rotating connecting rod to rotate via the lifting shaft.

[0019] Furthermore, in a preferred embodiment of the present invention, a spreading groove is provided on the rotating connecting rod, and an installation shaft is rotatably installed in the spreading groove, the installation shaft being installed on the inner wall of the welding host.

[0020] A retractable torsion spring is installed on the inner wall of the expanding slot, and the retractable torsion spring is mounted on the mounting shaft.

[0021] Furthermore, in a preferred embodiment of the present invention, the side-tilting support device further includes two driving rods, which are respectively mounted on two active brackets. Each of the two pull-out brackets is provided with a locking hole, and the active bracket is inserted into the locking hole to limit the position of the heat dissipation blow plate.

[0022] The welding host has two limiting grooves on its bottom side, and the two active inserts are slidably installed in the two limiting grooves respectively.

[0023] Furthermore, in a preferred embodiment of the present invention, synchronous push rods are installed on the two universal wheels located on the same side, and driving blocks are installed on both synchronous push rods. An inclined driving hole is opened on the driving block, and a driving shaft is installed on the driving rod. The driving shaft is movably installed in the inclined driving hole.

[0024] The welding host is equipped with pop-out slide rods at the four corners of its bottom side, and the four casters are slidably mounted on the four pop-out slide rods respectively. An external spring is installed between the welding host and the casters.

[0025] A method for welding and shaping an airfoil support blade, based on the aforementioned airfoil support blade welding and shaping device, includes the following steps:

[0026] S1. The heat dissipation space of the welding host is encroached upon, causing the heat dissipation blow plate to be blocked and retracted. The retraction of the heat dissipation blow plate drives the four synchronous push frames to move. The movement of the synchronous push frames compresses and pushes the lever to rotate. The rotation of the lever drives the connecting central shaft to rotate. The rotation of the connecting central shaft drives the flipping support frame to rotate. The rotation of the flipping support frame drives the two support wheels to rotate, so that the flipping support frame pushes against the obstruction through the two support wheels, pushing the welding host away.

[0027] S2. The heat dissipation blow plate is blocked and retracts, which drives the wedge-shaped push plate to move. The movement of the wedge-shaped push plate squeezes the upper push shaft to move. The upper push shaft drives the lifting rod to move, which in turn drives the rotating connecting rod to rotate through the lifting shaft. The rotation of the rotating connecting rod drives the two synchronous drive frames to move through the two synchronous drive shafts. The movement of the two synchronous drive frames drives the two heat dissipation sealing plates to move, so that the two heat dissipation sealing plates are retracted into the two recovery covers, thereby opening more heat dissipation holes and expanding the heat dissipation area.

[0028] S3. The welding host is knocked over and tipped over, causing the two casters on one side to leave the ground. At this time, under the tension of the outer spring, the casters are ejected. The movement of the casters drives the synchronous push rod to move, which in turn drives the drive block to move. The drive block moves the drive shaft by pressing through the inclined drive hole, which in turn drives the drive rod to move. The drive rod drives the active insert to slide horizontally in the limiting slide groove, so that the active insert is inserted into the locking hole, locking the pull-out bracket on the fallen side. This fixes the position of the heat dissipation blow plate on the fallen side, thus supporting the welding host.

[0029] The beneficial effects of the airfoil support blade welding and shaping device and method proposed in this invention are:

[0030] In this invention, by setting up an active spreading device, when the welding host is dissipating heat, if the welding host is pulled next to an obstruction, or the obstruction is moved to a position close to the welding host, the heat dissipation blower is blocked and retracted. The retraction of the heat dissipation blower drives four synchronous push frames to move. The movement of the synchronous push frames compresses and pushes the lever to rotate. The rotation of the lever drives the connecting central shaft to rotate. The rotation of the connecting central shaft drives the flipping spreading frame to rotate. The rotation of the flipping spreading frame drives two support wheels to rotate. Then, the flipping spreading frame pushes against the obstruction through the two support wheels, so that the flipping spreading frame pushes the welding host away, ensuring the heat dissipation space of the welding host, and thus ensuring the heat dissipation effect.

[0031] Furthermore, in this invention, by setting up a heat dissipation retaining device, when the heat dissipation blow plate is blocked and retracted, it drives the wedge-shaped push plate to move. The movement of the wedge-shaped push plate presses the upper push shaft to move, and the upper push shaft drives the lifting rod to move. This causes the lifting rod to drive the rotating connecting rod to rotate through the lifting shaft. The rotation of the rotating connecting rod drives the two synchronous drive frames to move through the two synchronous drive shafts. The movement of the two synchronous drive frames drives the two heat dissipation sealing plates to move, so that the two heat dissipation sealing plates are retracted into the two recovery covers, thereby opening more heat dissipation holes. This expands the heat dissipation area when the heat dissipation space of the welding host is blocked, thus maintaining the heat dissipation effect.

[0032] Furthermore, in this invention, by setting up a side-tipping support device, when the welding host is in use, if the welding host is knocked over and tipped over, causing the two universal wheels on one side to leave the ground, the universal wheels will be ejected under the tension of the external spring, driving the synchronous push rod to move. The synchronous push rod moves, driving the drive block to move. The drive block squeezes the drive shaft through the inclined drive hole, causing the drive shaft to drive the drive rod to move. The drive rod drives the active insert to slide horizontally in the limiting slide groove, causing the active insert to insert into the locking hole, locking the pull-out bracket on the fallen side, thereby fixing the position of the heat dissipation blower on the fallen side and preventing the welding host from falling to the ground and causing damage to the welding host.

[0051] Please refer to the attached instruction manual. Figures 1-11The present invention provides a welding and shaping device for airfoil support blades, which includes a welding host 1. Multiple heat dissipation holes 2 are provided on both sides of the welding host 1, and two cooling fans 4 are installed inside the welding host 1. Universal wheels 3 are movably installed at the four corners of the bottom side of the welding host 1.

[0052] Further, please refer to the appendix to the instruction manual. Figures 2-5 The airfoil support blade welding and shaping device provided in this embodiment of the invention further includes an active opening device 5, which is installed on the welding host 1 and is used to maintain the heat dissipation space of the welding host 1. Specifically, the active opening device 5 includes two heat dissipation blowing plates 501, which are movably installed on both sides of the welding host 1. A mounting base 502 is installed on the bottom side of the welding host 1. Pull-out brackets 503 are movably installed on both sides of the mounting base 502. A linkage bracket 505 is installed on each of the two pull-out brackets 503. The two linkage brackets 505 are respectively installed on the two heat dissipation blowing plates 501. Multiple flip-opening brackets 507 are rotatably installed on both sides of the welding host 1. Support wheels 508 are rotatably installed on both sides of the flip-opening brackets 507. The flip-opening brackets 507 rotate to open the welding host 1, thereby maintaining the heat dissipation space of the welding host 1.

[0053] It should be noted that in this embodiment of the invention, when the heat dissipation space of the welding host 1 is encroached upon, the heat dissipation blow plate 501 is blocked and retracted. The retraction of the heat dissipation blow plate 501 drives the rotation of multiple flip-out support frames 507. The rotation of the flip-out support frames 507 drives the rotation of two support wheels 508. The flip-out support frames 507 push against the obstruction through the two support wheels 508, so that the flip-out support frames 507 push the welding host 1 away, ensuring the heat dissipation space of the welding host 1, thereby ensuring the heat dissipation effect.

[0054] More specifically, in this embodiment of the invention, a heat dissipation retaining device 6 is installed inside the welding host 1. The heat dissipation retaining device 6 is used to maintain the heat dissipation range of the welding host 1. The heat dissipation retaining device 6 includes four recovery covers 601, which are respectively installed on the inner walls of both sides of the welding host 1. A heat dissipation sealing plate 602 is movably installed inside the recovery cover 601, and the heat dissipation sealing plate 602 is used to seal the heat dissipation holes 2. It should be noted that in this embodiment of the invention, when the heat dissipation blow plate 501 is blocked and retracted, the two heat dissipation sealing plates 602 are retracted into the two recovery covers 601, thereby opening more heat dissipation holes 2. This expands the heat dissipation area when the heat dissipation space of the welding host 1 is blocked, thus maintaining the heat dissipation effect.

[0055] More specifically, in this embodiment of the invention, a side-tipping support device 7 is also included. The side-tipping support device 7 is installed on the bottom side of the welding host 1 and is used to support the welding host 1. The side-tipping support device 7 includes two active brackets 701, both of which are slidably installed on the bottom side of the welding host 1. The two active brackets 701 are respectively inserted into two pull-out brackets 503, restricting the two pull-out brackets 503 and supporting the welding host 1. It should be noted that in this embodiment of the invention, when the welding host 1 is knocked over and tipped over, the two universal wheels 3 on one side leave the ground, thereby allowing the active brackets 701 to insert into the locking holes 702, locking the pull-out brackets 503 on the fallen side, thus fixing the position of the heat dissipation blower 501 on the fallen side and preventing the welding host 1 from falling to the ground and causing damage to the welding host 1.

[0056] Please continue to refer to the instruction manual appendix. Figures 2-5 Furthermore, the airfoil support blade welding shaping device provided in this embodiment of the invention includes an active spreading device 5 that further includes multiple mounting brackets 506, which are respectively mounted on both sides of the welding host 1. A connecting central shaft 510 is rotatably mounted on each of the multiple mounting brackets 506, and multiple flip spreading frames 507 are respectively mounted on the multiple connecting central shafts 510.

[0057] Furthermore, a push lever 511 is installed at one end of the connecting shaft 510, and four synchronous push frames 509 are installed on the heat dissipation blow plate 501. The movement of the heat dissipation blow plate 501 drives the push lever 511 to rotate through the synchronous push frames 509, which in turn drives the flip-open frame 507 to rotate. It should be noted that, in this embodiment of the invention, when the heat dissipation space of the welding host 1 is encroached upon, the heat dissipation blow plate 501 retracts, causing the four synchronous push frames 509 to move. The movement of the synchronous push frames 509 compresses the push lever 511 to rotate, thereby driving the flip-open frame 507 to rotate. The rotation of the flip-open frame 507 drives the two support wheels 508 to rotate, so that the flip-open frame 507 presses against the obstruction through the two support wheels 508, achieving the purpose of pushing the welding host 1 away through the flip-open frame 507.

[0058] More specifically, in this embodiment of the invention, the flip-out support frame 507 has two flip-out slots 512, and the connecting central shaft 510 is rotatably installed in the two flip-out slots 512; a flip-out torsion spring 513 is installed on the inner wall of the flip-out slot 512, and the flip-out torsion spring 513 is installed on the connecting central shaft 510. It should be noted that, in this embodiment of the invention, when the synchronous push frame 509 does not press the push lever 511, the flip-out torsion spring 513 drives the connecting central shaft 510 to rotate through rotational force, so that the connecting central shaft 510 drives the flip-out support frame 507 to adhere to the welding host 1.

[0059] More specifically, in this embodiment of the invention, a pull-back spring 504 is installed on the pull-out bracket 503, and the pull-back spring 504 is installed on the inner wall of the mounting base 502. It should be noted that in this embodiment of the invention, the pull-out bracket 503 can be pulled back by the contraction force of the pull-back spring 504.

[0060] Please refer to the instruction manual attached. Figure 2 and Figures 6-8 Furthermore, in this embodiment of the invention, the heat dissipation holding device 6 also includes a plurality of synchronous drive frames 603, which are respectively mounted on a plurality of heat dissipation sealing plates 602.

[0061] Furthermore, rotating connecting rods 604 are rotatably mounted on the inner walls of both sides of the welding host 1. Two synchronous drive shafts 606 are rotatably mounted on the rotating connecting rods 604, and the two synchronous drive shafts 606 are respectively movably mounted in two synchronous drive frames 603 located on the same side. It should be noted that, in this embodiment of the invention, when the rotating connecting rods 604 rotate, the two synchronous drive shafts 606 drive the two synchronous drive frames 603 to move, and at the same time, the two synchronous drive shafts 606 slide within the two synchronous drive frames 603. The movement of the two synchronous drive frames 603 drives the movement of the two heat dissipation plates 602, thereby achieving the purpose of synchronous movement of the two heat dissipation plates 602 located on the same side.

[0062] More specifically, in this embodiment of the invention, two lifting rods 607 are slidably installed on the inner wall of the top side of the welding host 1. Each of the two lifting rods 607 is equipped with an upward push shaft 608. Each of the two heat dissipation blowers 501 is equipped with a wedge-shaped push plate 609. The heat dissipation blower 501 drives the wedge-shaped push plate 609 to move, which is used to drive the upward push shaft 608 to move.

[0063] Furthermore, a lifting shaft 612 is installed on the lifting rod 607. The movement of the lifting rod 607 drives the rotating connecting rod 604 to rotate via the lifting shaft 612. It should be noted that, in this embodiment of the invention, when the heat dissipation blow plate 501 is blocked and retracts, it drives the wedge-shaped push plate 609 to move. The movement of the wedge-shaped push plate 609 presses the upper push shaft 608 to move. The upper push shaft 608 drives the lifting rod 607 to move, so that the lifting rod 607 drives the rotating connecting rod 604 to rotate via the lifting shaft 612, thereby driving the two heat dissipation sealing plates 602 to open, achieving the purpose of expanding the heat dissipation area.

[0064] More specifically, in this embodiment of the invention, a spreading groove 610 is provided on the rotating connecting rod 604, and an installation shaft 605 is rotatably mounted in the spreading groove 610. The installation shaft 605 is mounted on the inner wall of the welding host 1. In addition, a retractable torsion spring 611 is installed on the inner wall of the spreading groove 610, and the retractable torsion spring 611 is mounted on the installation shaft 605. It should be noted that, in this embodiment of the invention, when the rotating connecting rod 604 rotates, it rotates on the installation shaft 605 through the spreading groove 610, causing the retractable torsion spring 611 to be stressed. Therefore, under the rotational force of the retractable torsion spring 611, the rotating connecting rod 604 can automatically reset.

[0065] Please refer to the instruction manual attached. Figure 2 and Figures 9-11 Furthermore, the airfoil support blade welding and shaping device provided in this embodiment of the invention includes two driving rods 704, which are respectively installed on two active inserts 701. Both pull-out brackets 503 are provided with locking holes 702. The active inserts 701 are inserted into the locking holes 702 to limit the position of the heat dissipation blow plate 501.

[0066] Furthermore, two limiting grooves 703 are provided on the bottom side of the welding host 1, and two active inserters 701 are slidably installed in the two limiting grooves 703 respectively. It should be noted that, in this embodiment of the invention, when the welding host 1 tilts to the side, the driving rod 704 drives the active inserter 701 to slide horizontally in the limiting groove 703, so that the active inserter 701 inserts into the locking hole 702, locking the pull-out bracket 503 on the fallen side, thereby fixing the position of the heat dissipation blower 501 on the fallen side and supporting the welding host 1.

[0067] More specifically, in this embodiment of the invention, two universal wheels 3 located on the same side are equipped with synchronous push rods 705, and each synchronous push rod 705 is equipped with a drive block 706. The drive block 706 is provided with an inclined drive hole 707, and a drive shaft 708 is installed on the drive rod 704. The drive shaft 708 is movably installed in the inclined drive hole 707.

[0068] Furthermore, pop-out slide bars 709 are installed at the four corners of the bottom side of the welding host 1, and four universal wheels 3 are slidably mounted on the four pop-out slide bars 709 respectively. An external spring 710 is installed between the welding host 1 and the universal wheels 3. It should be noted that, in this embodiment of the invention, when the welding host 1 tilts, two universal wheels 3 on one side leave the ground. At this time, under the tension of the external spring 710, the universal wheels 3 are popped out, which drives the synchronous push rod 705 to move. The synchronous push rod 705 drives the driving block 706 to move. The driving block 706 presses the driving shaft 708 through the inclined driving hole 707, causing the driving shaft 708 to drive the driving rod 704 to move. The driving rod 704 drives the active insert 701 to insert into the locking hole 702, thereby achieving the purpose of locking the pull-out bracket 503.

[0069] In summary, the working principle of the airfoil support blade welding and shaping device provided in this embodiment of the invention, that is, the method corresponding to the airfoil support blade welding and shaping device of this embodiment of the invention, is as follows:

[0070] When the welding host 1 is dissipating heat, the cooling fan 4 blows air, causing the cooling blow plate 501 to be blown open. The cooling blow plate 501 moves within the mounting base 502 via the pull-out bracket 503, causing the pull-back spring 504 to be stretched by force. It should be noted that when the welding host 1 is in use, if the welding host 1 is pulled to the side of the obstruction, or the obstruction is moved to a position close to the welding host 1, causing the heat dissipation blow plate 501 to be blocked and retracted, the retraction of the heat dissipation blow plate 501 will drive the four synchronous push frames 509 to move. The synchronous push frames 509 will move and press the push lever 511 to rotate. The push lever 511 will rotate and drive the connecting central shaft 510 to rotate. The connecting central shaft 510 will rotate in the two flipping slots 512 and cause the two flipping torsion springs 513 to be stressed. At the same time, the rotation of the connecting central shaft 510 will drive the flipping support frame 507 to rotate. The rotation of the flipping support frame 507 will drive the two support wheels 508 to rotate. Therefore, the flipping support frame 507 will push the welding host 1 away through the two support wheels 508, ensuring the heat dissipation space of the welding host 1 and thus ensuring the heat dissipation effect.

[0071] Furthermore, when the heat dissipation blow plate 501 is blocked and retracts, it drives the wedge-shaped push plate 609 to move. The movement of the wedge-shaped push plate 609 presses the upper push shaft 608 to move. The upper push shaft 608 drives the lifting rod 607 to move, so that the lifting rod 607 drives the rotating connecting rod 604 to rotate through the lifting shaft 612. The rotating connecting rod 604 rotates on the mounting shaft 605 by opening the rotating groove 610, and causes the retracting torsion spring 611 to be stressed. It should be noted that the rotation of the rotating connecting rod 604 drives the two synchronous drive frames 603 to move through the two synchronous drive shafts 606. At the same time, the two synchronous drive shafts 606 slide within the two synchronous drive frames 603. The movement of the two synchronous drive frames 603 drives the two heat dissipation sealing plates 602 to move, so that the two heat dissipation sealing plates 602 are retracted into the two recovery covers 601, thereby opening more heat dissipation holes 2. This expands the heat dissipation area when the heat dissipation space of the welding host 1 is blocked, thus maintaining the heat dissipation effect.

[0072] Furthermore, when the welding host 1 is in use, if the welding host 1 is knocked over and tipped over, causing the two universal wheels 3 on one side to leave the ground, the universal wheels 3 will be ejected under the tension of the outer spring 710, which will drive the synchronous push rod 705 to move. The synchronous push rod 705 will drive the drive block 706 to move. The drive block 706 will push the drive shaft 708 to move through the inclined drive hole 707. This will cause the drive shaft 708 to drive the drive rod 704 to move. The drive rod 704 will drive the active insert 701 to slide horizontally in the limiting slide groove 703, so that the active insert 701 can be inserted into the locking hole 702, locking the pull-out bracket 503 on the fallen side. This will fix the position of the heat dissipation blow plate 501 on the fallen side, thereby preventing the welding host 1 from falling to the ground and causing damage to the welding host 1.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
