Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a center-positioning welding device for manufacturing motorcycle fuel pumps. Background Technology

[0002] In the manufacturing process of motorcycle fuel pumps, center-alignment welding equipment plays a crucial role. With the continuous development of motorcycle technology and the increasing demands of consumers for product performance, fuel pumps require higher precision and reliability. Center-alignment welding equipment, a key technology that has emerged in this context, ensures precise alignment and positioning during the welding process, achieving seamless connections between various parts. This equipment utilizes advanced sensors and control systems to automatically adjust the welding position with high precision, ensuring the accuracy of each weld point. This not only improves welding quality but also increases production efficiency. Traditional welding methods, relying on manual operation, are prone to centering deviations, leading to uneven weld strength or accelerated component wear. Therefore, center-alignment welding equipment is an indispensable part of the efficient manufacturing and quality assurance of motorcycle fuel pumps.

[0003] Currently, most of the self-aligning welding equipment on the market lacks an assembly line processing process. In the actual self-aligning welding process, most of them use a robotic arm to grasp and position the equipment for alignment. This step is not only cumbersome but also costly. Furthermore, most of the equipment is directly exposed during the welding process, and the strong light stimulation and gases generated during welding are not treated. After welding, most of them use natural heat dissipation to reduce the temperature of the fuel pump housing. When the temperature is high, deformation is likely to occur, which will affect the yield rate. Summary of the Invention

The alignment device design includes an alignment base plate with a dedicated feeding bracket firmly connected to its top, ensuring that the material entering the equipment can be smoothly delivered to the welding position. To increase the stability of the material, feeding baffles are provided on both sides of the alignment base plate. This design helps to avoid material deviation or asymmetry during the conveying process, thereby affecting the welding quality. A cleverly designed second bracket is added to the top of the centering base plate, located on the side away from the feed bracket. The special design of this second bracket allows for the fixed connection of the movable end of a first spring rod to its inner wall, the fixed end of which is connected to a guide plate. An arc-shaped rubber pad is fixed to the bottom center of the guide plate; this pad not only provides flexible cushioning for material alignment but also stabilizes and protects the material surface. The stability of the basic structure is achieved by a third bracket connected to the bottom of the centering base plate, making the overall structure more robust and ensuring a tight fit between the entire centering device and the bottom inner wall of the welding shell, preventing movement or loss of precision due to vibration or external forces. The centering mechanism at the top of the centering base plate plays a crucial adjustment role, achieving precise alignment and stable welding of each component. For efficient material feeding and unloading, the feed bracket is fixedly connected to the inner side of the welding shell, ensuring an accurate and clear feeding path. To achieve high adaptability to the actual operating environment, a special opening adapted to the feed bracket is provided on the side of the welding shell. In this way, the feeding bracket can not only transport materials smoothly, but also ensure that it can be adjusted at any time during the welding process, minimizing the errors that may be caused by human operation.

The connection point on the top side of the roller support is also ingeniously designed to coordinate with the centering base plate. The other end of the centering support is located away from the rotating shaft mechanism, allowing its end to rotate flexibly and connect to the support shaft. To ensure the entire support does not shift due to external forces during operation, a limiting seat is specifically fixedly connected to the bottom of the support shaft. The limiting seat is adapted to the first slide groove on the centering base plate, which can precisely control the sliding range of the support shaft, providing stability and accurate positioning.

This design provides a flexible sliding mechanism, allowing system components to run smoothly on the guide rail and achieve accurate positioning. The fixed end of the second spring rod is fixedly connected to the bottom of the support cavity. The top of the movable end of the second spring rod is a guide plate, and the top of this plate is connected to a rubber pad. The rubber pad provides a soft contact surface, effectively reducing wear and increasing the firmness of the fixation. To enhance the versatility of external connections, an arc-shaped fixing plate is fixed to the bottom side of the fixed base. The arc design helps to securely connect with the conveyor belt, which means additional flexibility and efficient transmission in automated operation. When working on the conveyor belt, the positioning block is connected to the fixed block via a connecting plate.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please see Figures 1-6The present invention provides a technical solution: a centering and positioning welding device for manufacturing a motorcycle fuel pump, comprising a support base plate 1, a first bracket 2 fixedly connected to the top of the support base plate 1, a welding shell 3 fixedly connected to the top of the first bracket 2, a centering device 4 fixedly connected to the inner wall side of the welding shell 3, a conveying device 5 fixedly connected to the bottom of the inner wall of the welding shell 3, a welding device 6 fixedly connected to the portion of the bottom of the inner wall of the welding shell 3 located on one side of the centering device 4, a discharge port 7 communicating with the bottom of the welding shell 3, and a unloading device 8 fixedly connected to the portion of the bottom of the inner wall of the welding shell 3 located above the discharge port 7. The centering device 4 includes a centering base plate 41. A feeding bracket 42 is fixedly connected to the top of the centering base plate 41. Feed baffles 43 are fixedly connected to both sides of the feeding bracket 42. A second bracket 44 is fixedly connected to the top of the centering base plate 41 away from the feeding bracket 42. The movable end of a first spring rod 45 is fixedly connected to the top of the inner wall of the second bracket 44. A first guide plate 46 is fixedly connected to the fixed end of the first spring rod 45. An arc-shaped rubber pad 47 is fixedly connected to the bottom center of the first guide plate 46. A third bracket 48 is fixedly connected to the bottom of the centering base plate 41. A centering mechanism 49 is fixedly connected to the top of the centering base plate 41. The bottom of the third bracket 48 is fixedly connected to the bottom of the inner wall of the welding shell 3. The feeding bracket 42 is fixedly connected to the inner side of the welding shell 3. An opening adapted to the feeding bracket 42 is provided on the side of the welding shell 3.

[0021] The centering mechanism 49 includes a motor bracket 491. A first servo motor 492 is fixedly connected to the side of the motor bracket 491. A screw 493 is fixedly connected to the drive shaft of the first servo motor 492. A movable baffle 494 is sleeved and threaded onto the screw 493. Roller brackets 495 are fixedly connected to both ends of the movable baffle 494. A fixing part of a rotating shaft mechanism 496 is fixedly connected to the side of the roller bracket 495. A centering roller 497 is rotatably connected to the top side of the roller bracket 495. The bottom of the roller support 495 is fixedly connected to a first guide rail 4912. The rotating part of the rotating shaft mechanism 496 is rotatably connected to a centering support 498. The end of the centering support 498 away from the rotating shaft mechanism 496 is rotatably connected to a support shaft 499. The bottom of the support shaft 499 is fixedly connected to a limiting seat 4910. The top of the centering base plate 41 is provided with a first sliding groove 4911 that matches the limiting seat 4910. The top of the centering base plate 41 is provided with a second sliding groove 4913 that matches the first guide rail 4912.

[0022] The bottom of the motor bracket 491 is fixedly connected to the top of the centering base plate 41, the roller bracket 495 is slidably connected to the centering base plate 41 through the second sliding groove 4913, the limiting seat 4910 is slidably connected to the centering base plate 41 through the first sliding groove 4911, and the bottom of the moving baffle 494 is in contact with the top of the centering base plate 41.

[0023] In use, the fuel pump housing is fed into the top of the feed bracket 42 by an external device. The fuel pump is fixed to the side of the centering roller 497 by gravity. The first servo motor 492 is started, and its drive shaft rotates, causing the screw 493 to rotate. The rotation of the screw 493 drives the moving baffle 494 to move via a thread. The moving baffle 494 moves the roller bracket 495, which slides on the top of the centering base plate 41 via the second sliding groove 4913. The moving mechanism drives the alignment rollers 497 to move, thereby changing the distance between the alignment rollers 497 to accommodate different fuel pump sizes. After the fuel pump enters the side of the alignment rollers 497, the first servo motor 492 drives the alignment rollers 497 to move closer, causing the fuel pump to move upward. The upward movement of the fuel pump drives the first guide plate 46 to move upward, compressing the first spring rod 45. The compressed first spring rod 45 generates a downward pressure, causing the fuel pump to fit tightly against the side of the alignment rollers 497. This achieves the alignment and positioning of the fuel pump, and also enables alignment operations when the fuel pump size is different.

[0024] Example 2: Please see Figures 1-10 Based on Embodiment 1, the present invention provides a technical solution: the conveying device 5 includes a fourth bracket 51, a second servo motor 52 is fixedly connected to the side of the fourth bracket 51, the input end of the conveyor belt 53 is fixedly connected to the drive shaft of the second servo motor 52, a bracket baffle 54 is fixedly connected to the side of the fourth bracket 51, a fixing device 56 is fixedly connected to the top of the conveyor belt 53, and multiple sets of fixing devices 56 are provided. The bottom of the fourth bracket 51 is fixedly connected to the bottom of the inner wall of the welded housing 3, and the bottom of the fourth bracket 51 is fixedly connected to the top of the inner wall of the welded housing 3.

[0025] The fixing device 56 includes a fixing base 561. A third sliding groove 5610 is formed on the side of the fixing base 561. A second guide rail 5611 is slidably connected to the inner wall of the third sliding groove 5610. A fixing block 562 is fixedly connected to the side of the second guide rail 5611. A supporting cavity 563 is fixedly connected to the top of the fixing block 562. Spring plates 564 are fixedly connected to both sides of the supporting cavity 563. A positioning block 565 is fixedly connected to the end of each spring plate 564 away from the supporting cavity 563. A second spring is fixedly connected to the bottom of the inner wall of the supporting cavity 563. The fixed end of the spring rod 566 and the top of the movable end of the second spring rod 566 are fixedly connected to a second guide plate 567. The top of the second guide plate 567 is fixedly connected to a rubber pad 568. The bottom side of the fixed base 561 is fixedly connected to an arc-shaped fixing plate 569. The side of the positioning block 565 is fixedly connected to a connecting plate 5612. The end of the connecting plate 5612 away from the positioning block 565 is rotatably connected to the side of the fixed block 562 through a rotating pin. The bottom of the arc-shaped fixing plate 569 is fixedly connected to the top of the conveyor belt 53. Multiple sets of fixing devices 56 are provided.

[0026] In use, the second servo motor 52 is started, and the drive shaft of the second servo motor 52 drives the conveyor belt 53 to rotate. The rotation of the conveyor belt 53 causes the fixing device 56 to move, and the fixing device 56 moves to fix the fuel pump. During the fixing process, the area below the housing enters the area between the top of the arc-shaped fixing plate 569 and the bottom of the fixing block 562. The second guide plate 567 is arc-shaped, and under the action of the second spring rod 566, the second guide plate 567 is pushed upward, thereby pushing the upper half of the fuel pump housing against it. During the movement of the fixing device 56, the housing is limited, thereby ensuring that the housing is locked into the designated position. During the movement of the fixing base 561, when the housing contacts the surface of the fixing base 561, the positioning block 565 is positioned at the arc shape of the housing and the fixing base 562. Under the squeezing action of the fixed base 561, the positioning block 565 rotates along the fixed block 562. The positioning block 565 rotates on both sides of the fixed block 562, causing the spring plate 564 to be compressed. The spring plate 564 is compressed, thus applying pressure to the positioning block 565 in the opposite direction. The positioning block 565 is supported on the inner wall of the housing, thereby enhancing the stability of the housing during welding. The second guide plate 567 is squeezed into the housing by the housing and the fixed base 561 at the same time. As the second guide plate 567 is inserted into the housing, it moves downward. The downward movement of the second guide plate 567 causes the second spring rod 566 to be compressed. The compression of the second spring rod 566 generates a reaction force that causes the second guide plate 567 to move upward, thereby making the rubber pad 568 on the top of the second guide plate 567 contact the top of the inner wall of the housing. The automatic loading and accurate centering of the housing are achieved. At the same time, the setting of spring plate 564 and second spring rod 566 ensures that welding errors caused by factors such as shaking are reduced during welding, thereby improving the yield rate.

[0027] Example 3: Please see Figures 1-12 Based on Embodiments 1 and 2, the present invention provides a technical solution: the welding device 6 includes a welding frame 61, a movable base 62 is slidably connected to the welding frame 61, a fixed part of a rotating table 63 is fixedly connected to the side of the movable base 62, a welding torch 64 is fixedly connected to the rotating part of the rotating table 63, a welding base 65 is fixedly connected to the bottom of the welding frame 61, a cleaning box 66 is slidably connected to the inner wall of the welding base 65, and a waste gas absorption device 67 is fixedly connected to the bottom of the welding base 65. The bottom of the waste gas absorption device 67 is fixedly connected to the bottom of the inner wall of the welding shell 3.

[0028] The waste gas absorption device 67 includes a water tank 671. A gas outlet pipe 672 is connected to the top of the water tank 671. An air inlet of an exhaust fan 673 is connected to the end of the exhaust pipe 672 away from the water tank 671. An air supply pipe 674 is connected to the outlet of the exhaust fan 673. Multiple sets of air supply pipe supports 675 are fitted and fixedly connected to the air supply pipe 674. Each air supply pipe support 675 is fixedly connected to the side of a welding base 65 and a welding frame 61. An air outlet bracket 676 is connected to the end of the air supply pipe 674 away from the exhaust fan 673. The top of the air outlet bracket 676 is fixedly connected to... A perforated baffle 677 is provided. An air suction pipe 6710 is fixedly connected through and to the side of the water tank 671. An arc-shaped air suction pipe 679 is connected to the end of the air suction pipe 6710 away from the water tank 671. An air extraction bracket 678 is fixedly connected to the top of the arc-shaped air suction pipe 679. A perforated pipe 6711 is fixedly connected to the inner wall of the water tank 671. The perforated pipe 6711 is connected to the air suction pipe 6710. A guide plate 6712 is fixedly connected to the inner wall of the water tank 671. The top of the air extraction bracket 678 is fixedly connected to the top of the inner wall of the welded shell 3. The bottom of the water tank 671 is fixedly connected to the bottom of the inner wall of the welded shell 3.

[0029] In use, the movable base 62 is activated, which drives the rotating table 63 to reciprocate along the welding frame 61. The rotating part of the rotating table 63 rotates, causing the welding torch 64 to rotate. The cleaning box 66 collects the welding slag generated during welding for easy cleaning. The exhaust fan 673 is activated to extract air from the upper part of the water tank 671 and send it into the air supply pipe 674. The air supply pipe 674 sends the air into the air outlet bracket 676, and the air is discharged from the opening at the top of the air outlet bracket 676. The bracket baffle 677 at the top of the air outlet bracket 676 prevents welding slag from falling directly into the air outlet bracket 676. The air passes through the welding torch. The area near 64 carries away the heat generated during welding and cools the completed fuel pump housing. After cooling, the air temperature rises, and the hot air spontaneously rises and is drawn into the intake pipe 6710 by the suction force of the arc-shaped intake pipe 679. The suction force inside the intake pipe 6710 comes from the exhaust fan 673. The water tank 671 is a sealed box. When the air is drawn out by the exhaust fan 673, a negative pressure is generated inside the water tank 671, which in turn generates suction force inside the intake pipe 6710. The exhaust gas is released into the water tank 671 through the porous pipe 6711. The substances in the exhaust gas are dissolved in the water, and the air is cooled. This achieves the treatment of exhaust gas during welding and the cooling treatment after welding, thereby avoiding the impact of deformation after high-temperature welding on the product yield.

[0031] The bottom of the unloading bracket 87 is fixedly connected to the bottom of the inner wall of the welded housing 3, and the top of the unloading bracket 87 is fixedly connected to the top of the inner wall of the welded housing 3. The rotor 81 is located above the discharge port 7.

[0032] In use, the second servo motor 52 is started. The drive shaft of the second servo motor 52 drives the input end of the belt drive mechanism 86 to rotate. The rotation of the belt drive mechanism 86 drives the rotating shaft 85 to rotate. The rotation of the rotating shaft 85 drives the rotor 81 to rotate. The rotation of the rotor 81 drives the connecting rod 82 to rotate. The rotation of the connecting rod 82 drives the unloading fork 83 to rotate. The rotation of the unloading fork 83 drives the unloading pad 84 to rotate. The rotation of the unloading pad 84 removes the fuel pump housing fixed on the fixing device 56. Automatic unloading is achieved by utilizing the angular velocity difference between the driving wheel and the driven wheel in the belt drive mechanism, thereby completing the assembly line operation and realizing the automatic unloading process. The setting of the unloading pad 84 avoids damage to the fuel pump housing.
