Description

Technical Field

[0001] This invention relates to the field of laser welding technology, and more specifically, to a laser welding apparatus for processing liquid-cooled manifolds. Background Technology

[0002] The manifold of the liquid cooling plate is a key component in the liquid cooling system. It is mainly used for the distribution and collection of coolant. Its application is widespread and directly affects the heat dissipation efficiency and stability of the system.

[0003] In traditional partial laser welding devices, the two manifolds to be welded are first joined together, clamped and fixed, and then the operator moves the laser welding head to the weld position. The operator holds the laser welding head and moves it in a circular motion around the weld seam to complete the laser welding of the manifold. However, when using traditional partial laser welding heads for circumferential welding of manifolds, the laser welding head may shift position during the welding process because the operator holds the laser welding head. This results in the laser welding head not being able to accurately weld the weld seam of the manifold, affecting the welding quality. Moreover, the process of clamping the manifold before welding further reduces the welding efficiency of the laser welding head. Summary of the Invention

[0004] The purpose of this invention is to provide a laser welding apparatus for processing liquid-cooled manifolds, thereby solving the problems mentioned in the background art.

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

[0006] A laser welding device for processing liquid-cooled manifolds includes a laser welding machine and two support rings fixedly mounted on its surface. Each support ring has a rotating ring on its inner side, and a rotating cylinder is rotatably connected inside each support ring. The manifold body to be welded is placed inside each rotating cylinder.

Rotating plates are rotatably connected inside each of the through slots, and the surfaces of the rotating plates are provided with sloped surfaces. Through-type guide rods are slidably connected to the inner walls of each of the slots. One end of the guide rod extends into the interior of the through slot, and a movable plate is fixedly mounted on the other end of the guide rod. Multiple arc-shaped grooves are formed on the surface of the rotating rings. Multiple arc-shaped grooves are slidably connected to matching arc-shaped blocks inside. Multiple arc-shaped grooves are slidably connected to the inner walls of multiple arc-shaped grooves with through rods.

Multiple arc-shaped blocks are slidably connected to connecting plates inside, and multiple arc-shaped blocks and connecting plates are connected end to end to form a ring track. A lifting frame that can move vertically up and down is set above the two rotating rings. Connecting frames are fixedly installed on the bottom surfaces of both ends of the lifting frame. Rollers are rotatably connected to the bottom of the two connecting frames. A laser welder for welding the manifold body is fixedly installed in the middle of the bottom surface of the lifting frame. Multiple sliders are rotatably connected inside the circular seat, and the sliders are fixedly connected to the movable plate.

[0007] Preferably, the laser welding equipment has two base plates fixedly installed on its surface. The two base plates are located inside the two support rings, and the top surface of the base plates is rotatably connected to the rotating ring. The side surface of any connecting plate is chamfered, and the interior of any arc block is provided with an arc groove. The arc groove matches the connecting plate, and the connecting plate is slidably connected to the arc block through the arc groove. A spring is elastically connected between the connecting plate and the arc groove.

The slider matches the ring seat, and the slider does not detach from the ring seat.

[0008] Preferably, the inner wall of any arc-shaped groove is provided with a through hole, and the through hole matches the through rod. The through rod is slidably connected to the rotating ring through the through hole. The surface of any guide rod is fitted with a second spring for its movement reset. One end of the second spring is fixedly connected to the movable plate, and the other end of the second spring is fixedly connected to the inner wall of the groove.

[0009] Preferably, a spring shaft is provided between any rotating plate and the through groove. The rotating plate is rotatably connected to the through groove through the spring shaft. The inner walls of the two support rings are provided with rotating groove 1. A rotating block 1 that matches the rotating groove 1 is fixedly installed on one end surface of the two rotating cylinders, and the rotating block 1 is rotatably connected to the rotating groove 1. The inner walls of the two rotating rings are provided with rotating groove 2. Multiple rotating blocks 2 are fixedly installed on the other end surface of the two rotating cylinders, and the rotating blocks 2 are fixedly connected to the rotating groove 2.

[0010] Preferably, a gear ring is fixedly installed on the center of the surface of each of the two rotating drums, and two mounting seats are fixedly installed on the surface of the laser welding equipment. The two mounting seats are rotatably connected to a rotating shaft. The surface of the rotating shaft is coaxially fixedly mounted with gears that mesh with the gear rings. A motor is fixedly installed on the surface of one of the mounting seats, and the output end of the motor is fixedly connected to the rotating shaft.

[0011] Preferably, the laser welding equipment has a housing fixedly mounted on its surface, an expansion joint fixedly mounted on the bottom surface of the housing, a U-shaped frame fixedly mounted on the expansion end of the expansion joint, wheels rotatably connected to both ends of the bottom surface of the U-shaped frame, a lifting frame fixedly connected to the middle of the bottom surface of the U-shaped frame, a bracket fixedly mounted on the surface of the housing, a controller fixedly mounted on the surface of the bracket, the controller electrically connected to the expansion joint via wires, and the controller electrically connected to the motor via wires.

[0012] Preferably, the surface of the laser welding equipment has two corresponding movable slots. The interior of the two movable slots is slidably connected to a matching slide plate and a movable block. A slide block is fixedly installed on the top surface of the movable block. A matching movable plate is slidably connected inside the slide block. A fixed socket is fixedly installed on the surface of the laser welding equipment. The fixed socket is located on one side of one of the movable slots. After the slide block moves and matches with the fixed socket, the movable plate slides from inside the slide block to inside the fixed socket.

[0013] Preferably, a flat rail frame is fixedly installed on the surface of both the slide plate and the moving plate, and an inclined rail frame connected to the flat rail frame is fixedly installed on the top surface of both the slide plate and the moving plate. Springs are elastically connected between the slide plate and the moving groove and between the moving block and the moving groove.

[0014] Preferably, both the inner sides of the skateboard and the moving board are rotatably connected to a rotating shaft, and a turntable is fixedly installed at one end of each rotating shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) During the use of this laser welding device for processing liquid-cooled manifolds, the two manifold bodies move and compress multiple rotating plates within the through groove. The rotation of these rotating plates, along with the movement of the inclined surface, compresses the guide rod. The guide rod's movement causes the movable plate to move, which in turn moves the slider, causing the two annular seats to move towards each other, carrying the through rod. The through rod then carries multiple arc-shaped blocks out of the arc-shaped groove. After the arc-shaped blocks exit the groove, the connecting plate inside the arc-shaped block moves under the action of a spring. The connecting plate then contacts another arc-shaped block. When multiple arc-shaped blocks on both sides exit, combined with the contact of the connecting plate, the arc-shaped blocks and the connecting plate connect end-to-end, forming a circular track. The two rotating drums rotate, causing the manifold bodies to rotate as well. During this rotation, the laser welder welds the two manifold bodies at their mating points. Furthermore, during the welding process, two rollers rotate on a rotating ring track, further ensuring precise welding of the manifold bodies at the mating points. Compared to some traditional laser welding devices, the laser welder's use of two rollers on a rotating ring track during the welding process prevents deviation and ensures precise welding of the manifold bodies, guaranteeing the welding quality.

[0017] 2) When using this laser welding device for processing liquid-cooled manifolds, the telescopic device extends and moves the U-shaped frame downwards. The downward movement of the U-shaped frame moves the rotating wheel downwards. The rotating wheel first contacts and presses against the inclined rail frame. After being pressed, the two inclined rail frames move towards each other with the sliding plate and the moving plate. The sliding plate moves inside the moving groove, and the moving plate moves the moving block inside the moving groove. The moving plate and the moving plate move towards each other, causing the rotating shaft and the turntable to move towards the rotating cylinder. The two turntables move towards each other, pushing the two manifold bodies to move towards each other for docking. After docking, the docking position of the two manifold bodies can be welded. Compared with traditional welding devices, this laser welding equipment completes the docking and limiting of the two manifold bodies as the laser welder approaches the manifold body. The operation process is quick and labor-saving, improving the welding efficiency of the laser welder on the manifold body.

[0018] 3) When using this laser welding device for processing liquid-cooled manifolds, after the rotating wheel disengages from the inclined rail frame, the sliding plate and the moving plate are reset under the action of the three springs, causing the two turntables to disengage from the manifold body. During the reset process of the moving plate, it first resets with the moving block under the action of the three springs, and the reset of the moving block resets the slide and the moving plate. After the slide is reset, it connects with the fixed socket. At this time, the moving plate is pushed towards the fixed socket, and the moving plate moves from inside the slide to inside the fixed socket, moving the turntables. The movement of the turntables is misaligned with the position where the manifold body is pulled out, making it convenient to remove the welded manifold body. Attached Figure Description

[0033] Please see Figure 1 - Figure 13A laser welding device for processing liquid-cooled manifolds includes a laser welding device 1 and two support rings 2 fixedly mounted on its surface. The laser welding device 1 is used to weld the manifold body 5. A rotating ring 3 is provided on the inner side of each of the two support rings 2. A rotating cylinder 4 is rotatably connected inside each of the two support rings 2. The manifold body 5 to be welded is placed inside each of the two rotating cylinders 4. The manifold body 5 is a conventional manifold body 5 in the prior art. Multiple through grooves 6 are formed on the surface of each of the two rotating cylinders 4. Multiple slots 7 corresponding to the through grooves 6 are formed on the surface of each of the multiple through grooves 6. A rotating plate 8 is rotatably connected inside each of the multiple through grooves 6. A slope surface 9 is provided on the surface of each of the multiple rotating plates 8. The slope surface 9 is used to compress a guide rod 10. The multiple slots 7... The inner walls of the rotating ring 3 are slidably connected with through-type guide rods 10, which guide the movement of the movable plate 11. One end of the guide rod 10 extends into the interior of the through groove 6, and the other end of the guide rod 10 is fixedly installed with the movable plate 11. The surface of the rotating ring 3 is provided with multiple arc-shaped grooves 12, and each arc-shaped groove 12 is slidably connected with a matching arc-shaped block 15. The inner walls of the multiple arc-shaped grooves 12 are slidably connected with through-type through-rods 13, which guide the movement of the arc-shaped blocks 15. One end of each through-rod 13 is fixedly installed with a ring seat 14, and the other end of the through-rod 13 is fixedly connected to the arc-shaped block 15. Each arc-shaped block 15 is slidably connected with a connecting plate 16, and the multiple arc-shaped blocks 15 and the connecting plate 16 are connected end to end to form a ring rail. Above the two rotating rings 3, there is a... A lifting frame 18 capable of vertical up-and-down movement is provided. Connecting frames 19 are fixedly installed on the bottom surfaces of both ends of the lifting frame 18. Rollers 20 are rotatably connected to the bottom of each connecting frame 19. The rollers 20 move on the surface of the ring track, allowing the laser welder 21 to weld the two manifold bodies 5 more precisely. A laser welder 21 for welding the manifold bodies 5 is fixedly installed in the center of the bottom surface of the lifting frame 18. The laser welder 21 is a conventional laser welder in the prior art. Multiple sliders 25 are rotatably connected inside the annular seat 14. The design of the annular seat 14 and sliders 25 allows multiple arc-shaped blocks 15 to move simultaneously. The sliders 25 are fixedly connected to the movable plate 11. During the docking process of the manifold bodies 5, the two manifold bodies 5 move and press against each other. Multiple rotating plates 8 rotate within the through groove 6. The rotation of these plates causes the inclined surface 9 to move, pressing against the guide rod 10. The guide rod 10 then moves the movable plate 11, which in turn moves the slider 25. This causes the two annular seats 14 to move towards each other, moving the through rod 13. The through rod 13 carries multiple arc-shaped blocks 15 out of the arc-shaped groove 12. After the arc-shaped blocks 15 exit the arc-shaped groove 12, the connecting plate 16 inside them moves under the action of spring 23. The connecting plate 16 then exits the arc-shaped groove 22 and contacts another arc-shaped block 15. With the multiple arc-shaped blocks 15 exiting from both sides, and the contacting motion of the connecting plate 16, the arc-shaped blocks 15 and the connecting plate 16 connect end-to-end, forming a circular track. The motor 36 rotates, causing the rotating shaft 34 to rotate.The rotating shaft 34 rotates, causing two gears 35 to rotate. The two gears 35 rotate, causing two gear rings 32 to rotate. The gear rings 32 rotate, causing rotating cylinders 4 to rotate. The two rotating cylinders 4 rotate, causing the manifold bodies 5 to rotate. During the rotation of the two manifold bodies 5, the laser welder 21 works to weld the mating positions of the two manifold bodies 5. During the welding process, two rollers 20 rotate on a rotating ring track, further ensuring precise welding of the two manifold bodies 5 by the laser welder 21. Compared to some traditional laser welding devices, the two rollers 20 rotating on a rotating ring track during the welding process of the two rotating manifold bodies 5 prevent the laser welder 21 from shifting during welding, and simultaneously achieve precise welding of the two manifold bodies 5 by the laser welder 21, ensuring the welding quality of the manifold bodies 5.

[0034] Please see Figure 1 - Figure 13 Two base plates 54 are fixedly installed on the surface of the laser welding equipment 1. The two base plates 54 are located inside the two support rings 2, and the top surface of the base plates 54 is rotatably connected to the rotating ring 3. A chamfer 17 is opened on the side surface of any connecting plate 16. The slider 25 resets, which in turn resets the ring seat 14, thereby causing the arc block 15 to move into the arc groove 12. During the movement of the arc block 15 into the arc groove 12, the chamfer 17 on the side of the connecting plate 16 is squeezed by the wall edge of the arc groove 12 and moves into the arc block 15 to compress the spring 23. This allows the arc-shaped block 15 to retract. Each arc-shaped block 15 has an arc groove 22 inside. The arc groove 22 matches the connecting plate 16, and the connecting plate 16 is slidably connected to the arc-shaped block 15 through the arc groove 22. A spring 23 is elastically connected between the connecting plate 16 and the arc groove 22. The spring 23 is used for the movement reset of the connecting plate 16. One end of the spring 23 is fixedly connected to the connecting plate 16, and the other end of the spring 23 is fixedly connected to the inner wall of the arc groove 22. The slider 25 matches the ring seat 14, and the slider 25 does not detach from the ring seat 14.

[0035] Please see Figure 12 and Figure 13 Each arc-shaped groove 12 has a through hole 24 on its inner wall, and the through hole 24 matches the through rod 13. The through rod 13 is slidably connected to the rotating ring 3 through the through hole 24. Each guide rod 10 has a spring 26 for its movement reset on its surface. The spring 26 is used for the movement reset of the movable plate 11. One end of the spring 26 is fixedly connected to the movable plate 11, and the other end of the spring 26 is fixedly connected to the inner wall of the groove 7.

[0036] Please see Figure 8 - Figure 13A spring shaft 27 is provided between any rotating plate 8 and the through groove 6. The spring shaft 27 is a conventional spring shaft 27 in the prior art. The rotating plate 8 is rotatably connected to the through groove 6 through the spring shaft 27. The inner walls of the two support rings 2 are provided with rotating grooves 28. One end surface of the two rotating cylinders 4 is fixedly installed with rotating blocks 29 that match the rotating grooves 28, and the rotating blocks 29 are rotatably connected to the rotating grooves 28. The inner walls of the two rotating rings 3 are provided with rotating grooves 30. The other end surface of the two rotating cylinders 4 is fixedly installed with multiple rotating blocks 31, and the rotating blocks 31 are fixedly connected to the rotating grooves 30.

[0037] Please see Figure 5 A gear ring 32 is fixedly installed on the center of the surface of each of the two rotating drums 4. Two mounting seats 33 are fixedly installed on the surface of the laser welding equipment 1. A rotating shaft 34 is rotatably connected between the two mounting seats 33. Gears 35 that mesh with the gear ring 32 are fixedly installed on the surface of the rotating shaft 34 on the same axis. A motor 36 is fixedly installed on the surface of one of the mounting seats 33. The motor 36 is a conventional electric motor in the prior art. The output end of the motor 36 is fixedly connected to the rotating shaft 34.

[0038] Please see Figure 1 - Figure 4A housing 37 is fixedly mounted on the surface of the laser welding equipment 1. A telescopic device 38 is fixedly mounted on the bottom surface of the housing 37. The telescopic device 38 is a conventional electrically controlled push rod in the prior art. A U-shaped frame 52 is fixedly mounted on the telescopic end of the telescopic device 38. Both ends of the bottom surface of the U-shaped frame 52 are rotatably connected to a wheel 53. The design of the wheel 53 reduces friction on the flat rail frame 48 and the inclined rail frame 47. The middle of the bottom surface of the U-shaped frame 52 is fixedly connected to the lifting frame 18. A bracket 39 is fixedly mounted on the surface of the housing 37. A controller 40 is fixedly mounted on the surface of the bracket 39. The controller 40 is a conventional programmable control device in the prior art. The controller 40 controls the operation of the motor 36 and the telescopic device 38, which is prior art and will not be described in detail here. The controller 40 is electrically connected to the telescopic device 38 through wires. The controller 40 is electrically connected to the motor 36 through wires. The telescopic device 38 extends and moves the U-shaped frame 52 downward. The downward movement of the laser welding device 1 causes the rotating wheel 53 to move downward. The rotating wheel 53 first contacts the inclined rail frame 47 and squeezes it. After being squeezed, the two inclined rail frames 47 move towards each other, causing the sliding plate 42 and the moving plate 45 to move. The sliding plate 42 moves inside the moving groove 41, and the moving plate 45 moves the moving block 43 inside the moving groove 41. The moving of the sliding plate 42 and the moving plate 45 towards each other causes the rotating shaft 50 and the turntable 51 to move towards the rotating cylinder 4. The moving of the two turntables 51 towards each other pushes the two manifold bodies 5 to move towards each other for docking. After docking, the docking position of the two manifold bodies 5 can be welded. Compared with traditional welding devices, this laser welding device 1 completes the docking and limiting of the two manifold bodies 5 when the laser welder 21 approaches the manifold body 5. The operation process is quick and labor-saving, which improves the welding efficiency of the laser welder 21 on the manifold body 5.

[0039] Please see Figure 1 - Figure 7The laser welding equipment 1 has two corresponding movable slots 41 on its surface. Inside each slot 41, a matching sliding plate 42 and a movable block 43 are slidably connected. A slide block 44 is fixedly mounted on the top surface of the movable block 43. Inside the slide block 44, a matching movable plate 45 is slidably connected. A fixed socket 46 is fixedly mounted on the surface of the laser welding equipment 1, located on one side of one of the movable slots 41. After the slide block 44 moves to match and engage with the fixed socket 46, the movable plate 45 slides from inside the slide block 44 into the fixed socket 46. When the rotating wheel 53 disengages from the inclined rail frame 47... At this time, the slide plate 42 and the movable plate 45 are reset under the action of the spring 3 49, so that the two turntables 51 are separated from the manifold body 5. During the reset process of the movable plate 45, it first resets with the movable block 43 under the action of the spring 3 49. The reset of the movable block 43 resets the slide 44 and the movable plate 45. After the slide 44 is reset, it docks with the fixed socket 46. At this time, the movable plate 45 is pushed towards the fixed socket 46. The movable plate 45 moves from the inside of the slide 44 to the inside of the fixed socket 46, moving the turntable 51. The movement of the turntable 51 is misaligned with the position where the manifold body 5 is pulled out, making it convenient to remove the welded manifold body 5.

[0040] A flat rail frame 48 is fixedly installed on the surface of both the slide plate 42 and the movable plate 45. An inclined rail frame 47 connected to the flat rail frame 48 is fixedly installed on the top surface of both the slide plate 42 and the movable plate 45. A spring 3 49 is elastically connected between the slide plate 42 and the movable groove 41 and between the movable block 43 and the movable groove 41.

[0041] Both the inner sides of the skateboard 42 and the movable board 45 are rotatably connected to a rotating shaft 50, and a turntable 51 is fixedly installed at one end of each rotating shaft 50.

[0042] The steps of using this invention are as follows: When using this laser welding device for processing liquid-cooled manifolds, during the welding process of the manifold body 5, firstly, place the two manifold bodies 5 from the ends of the two rotating drums 4 respectively. After the two manifold bodies 5 are placed at the ends of the rotating drums 4, operate the controller 40. The controller 40 controls the telescopic device 38 to extend. The extension of the telescopic device 38 moves the U-shaped frame 52 downward. The downward movement of the U-shaped frame 52 moves the rotating wheel 53 downward. The downward movement of the rotating wheel 53 first contacts the inclined rail frame 47 and squeezes it. After the two inclined rail frames 47 are squeezed, they move the sliding plate 42 and the moving plate 45 towards each other. The sliding plate 42 moves inside the moving groove 41 to compress the spring 3 49. The moving plate 45 moves, moving the moving block 43 inside the moving groove 41. The moving compression spring 49, the sliding plate 42, and the moving plate 45 move towards each other, causing the rotating shaft 50 and the turntable 51 to move towards the rotating cylinder 4. The two turntables 51 move towards each other, pushing the two manifold bodies 5 to move towards each other and dock. During the docking process, the two manifold bodies 5 move and squeeze multiple rotating plates 8 to rotate in the through groove 6. The rotation of multiple rotating plates 8 causes the inclined surface 9 to move and squeeze the guide rod 10. The movement of the guide rod 10 causes the movable plate 11 to move and stretch the spring 26. The movement of the movable plate 11 causes the slider 25 to move, causing the two annular seats 14 to move towards each other and drive the through rod 13 to move. Multiple through rods 13 carry multiple arc blocks 15 out of the arc groove 12. After the arc blocks 15 have moved out of the arc groove 12, the connecting plate 1 inside the arc block 15 is at this time. 6. Under the action of spring 23, the connecting plate 16 moves out from inside the arc groove 22 and contacts another arc block 15. After the multiple arc blocks 15 on both sides move out, coupled with the movement of the connecting plate 16, the arc blocks 15 and the connecting plate 16 connect end to end to form a ring track. After the ring track is formed, the two manifold bodies 5 are docked. The inner surfaces of the multiple rotating plates 8 contact the surface of the manifold body 5, and the multiple rotating plates 8 have a clamping force on the manifold body 5 under the action of spring shaft 27. At this time, the rotating wheel 53 moves from the inclined rail frame 47 to the surface of the flat rail frame 48. As the telescopic device 38 continues to extend, the rotating wheel 53 moves on the surface of the flat rail frame 48 and will not squeeze the slide plate 42 and the moving plate 45 again. The telescopic device 38 continues to extend with the U-shaped frame. 52 moves downwards, and the downward movement of the U-shaped frame 52 also moves the lifting frame 18 downwards. The downward movement of the lifting frame 18 moves the two connecting frames 19 and rollers 20 downwards. After the rollers 20 contact the surface of the formed ring track, the extension device 38 stops extending. At this time, the laser welder 21 follows the movement of the lifting frame 18 to align with the docking part of the two manifold bodies 5. When welding the docking part of the two manifold bodies 5, the laser welder 21 starts working, and at the same time, the motor 36 starts rotating. The rotation of the motor 36 drives the rotating shaft 34 to rotate, the rotation of the rotating shaft 34 drives the two gears 35 to rotate, the rotation of the two gears 35 drives the two gear rings 32 to rotate, the rotation of the gear rings 32 drives the rotating drum 4 to rotate, and the rotation of the rotating block 29 rotates inside the rotating groove 28.The rotation of the rotating drum 4 also causes the rotating block 31 to rotate, which in turn causes the rotating ring 3 to rotate, completing the docking of the two manifold bodies 5. Since the inner surfaces of the multiple rotating plates 8 are in contact with the surface of the manifold body 5, and the multiple rotating plates 8 exert a clamping force on the manifold body 5 under the action of the spring shaft 27, the rotation of the two rotating drums 4 causes the manifold body 5 to rotate. Simultaneously, the rotating ring 3 follows the rotation of the rotating drums 4, causing the through rod 13 to rotate. This results in the multiple arc-shaped blocks 15 and the connecting plate 16 forming a rotating ring track. During the rotation of the two manifold bodies 5, the laser welder 21 works to weld the docking position of the two manifold bodies 5. Furthermore, during the welding process of the laser welder 21, the two rollers 20 rotate on the rotating ring track, further ensuring the stability of the laser welder 21. 1. Perform precise welding at the docking positions of the two manifold bodies 5. After welding, stop the motor 36, and the telescopic device 38 retracts to reset. The resetting of the telescopic device 38 moves the U-shaped frame 52 upward, which in turn moves the turntable 53 upward. When the turntable 53 disengages from the inclined rail frame 47, the slide plate 42 and the moving plate 45 are reset under the action of the spring 3 49, causing the two turntables 51 to disengage from the manifold bodies 5. During the resetting process of the moving plate 45, it first moves the moving block 43 to reset under the action of the spring 3 49. The resetting of the moving block 43 moves the slide seat 44 and the moving plate 45 to reset. After the slide seat 44 resets, it docks with the fixed socket 46. At this time, push the moving plate 45 towards the fixed socket 46. The moving plate 45 moves from inside the slide seat 44. The rotating plate 51 moves inside the fixed socket 46, causing a misalignment between the rotating plate 51 and the position where the manifold body 5 is pulled out. The welded manifold body 5 is then manually pulled out. After the manifold body 5 is pulled out, multiple rotating plates 8 reset under the action of spring shaft 27, and the movable plate 11 resets under the action of spring 26, causing the slider 25 to reset as well. The reset of slider 25 causes the annular seat 14 to reset, thereby causing the arc-shaped block 15 to move into the arc-shaped groove 12. During the movement of the arc-shaped block 15 into the arc-shaped groove 12, the chamfer 17 on the side of the connecting plate 16 is squeezed by the wall edge of the arc-shaped groove 12, compressing the spring 23 and thus retracting the arc-shaped block 15. In this scheme, during the docking process of the manifold bodies 5, the movement and compression of the two manifold bodies 5... Multiple rotating plates 8 rotate within the through groove 6. The rotation of these plates causes the inclined surface 9 to move, pressing against the guide rod 10. The guide rod 10 then moves the movable plate 11, which in turn moves the slider 25. This causes the two annular seats 14 to move towards each other, moving the through rod 13. The through rod 13 carries multiple arc-shaped blocks 15 out of the arc-shaped groove 12. After the arc-shaped blocks 15 exit the arc-shaped groove 12, the connecting plate 16 inside them moves under the action of spring 23. The connecting plate 16 then exits the arc-shaped groove 22 and contacts another arc-shaped block 15. With the multiple arc-shaped blocks 15 exiting from both sides, and the contacting motion of the connecting plate 16, the arc-shaped blocks 15 and the connecting plate 16 connect end-to-end, forming a circular track. The motor 36 rotates, causing the rotating shaft 34 to rotate.The rotating shaft 34 rotates, causing two gears 35 to rotate. The two gears 35 rotate, causing two gear rings 32 to rotate. The gear rings 32 rotate, causing rotating cylinders 4 to rotate. The two rotating cylinders 4 rotate, causing the manifold bodies 5 to rotate. During the rotation of the two manifold bodies 5, the laser welder 21 works to weld the mating positions of the two manifold bodies 5. During the welding process, two rollers 20 rotate on a rotating ring track, further ensuring precise welding of the two manifold bodies 5 by the laser welder 21. Compared to traditional partial laser welding devices, the two rollers 20 rotating on a rotating ring track during the welding of the two rotating manifold bodies 5 prevent the laser welder 21 from shifting during welding, and simultaneously achieve precise welding of the two manifold bodies 5 by the laser welder 21, ensuring the welding quality of the manifold bodies 5. The telescopic device 38 extends... The U-shaped frame 52 moves downwards, which in turn moves the rotating wheel 53 downwards. The rotating wheel 53 first contacts and presses against the inclined rail frame 47. After being pressed, the two inclined rail frames 47 move towards each other, carrying the sliding plate 42 and the moving plate 45. The sliding plate 42 moves inside the moving groove 41, and the moving plate 45 moves the moving block 43 inside the moving groove 41. The opposing movement of the sliding plate 42 and the moving plate 45 causes the rotating shaft 50 and the turntable 51 to move towards the rotating cylinder 4. The opposing movement of the two turntables 51 pushes the two manifold bodies 5 to move towards each other for docking. After docking, the docking position of the two manifold bodies 5 can be welded. Compared with traditional welding devices, this laser welding equipment 1 completes the docking and limiting of the two manifold bodies 5 while the laser welder 21 is approaching the manifold bodies 5. The operation is quick and labor-saving, improving the welding efficiency of the laser welder 21 on the manifold bodies 5.
