Description

Technical Field

[0001] This invention relates to the field of brazing technology, specifically to an automatic feeding and positioning high-speed brazing machine. Background Technology

[0002] High-frequency induction brazing technology is widely used in coaxial connection processes for various tubular workpieces due to its advantages such as fast heating speed, small heat-affected zone, and high welding efficiency. At present, the industry has formed an automated brazing production process covering workpiece loading, positioning and clamping, induction heating, and finished product unloading, providing a mature technical solution for the mass assembly of pipeline systems.

[0003] In the coaxial brazing operation of large and small pipes with clearance fit, three core processes need to be completed in sequence: coaxial positioning of the workpiece, quantitative feeding of solder paste, and induction heating welding. The volume of the annular brazing gap of pipe workpieces with different diameters varies, and the required amount of solder paste is also different. At the same time, the coating method of solder paste will directly affect its distribution in the annular gap, thereby affecting the forming quality and mechanical properties of the welded joint.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic feeding and positioning high-speed brazing welding machine to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding and positioning high-speed brazing welding machine, comprising a frame, a welding machine body mounted on the upper end of the frame, a brazing coil mounted on one side of the welding machine body, and a positioning calibration component provided on the upper end of the brazing coil on the corresponding side of the welding machine body; The positioning calibration component includes a support frame installed on one side of the welding machine body. A dual-channel cylinder is installed on the upper end of the support frame. The first output end of the dual-channel cylinder is connected to a first bracket. A positioning cone is connected to the lower end of the first bracket. A support sleeve is connected to one side of the support frame. The lower end of the bearing sleeve is rotatably connected to a rotating cylinder. A first stop block is connected to one side of the outer wall of the rotating cylinder. A second stop block is connected to the bearing sleeve corresponding to the first stop block. An arc-shaped spring is connected to the side of the first stop block and the second stop block that are far apart from each other. Several material cylinders are slidably connected to the lower end of the rotating cylinder in a ring array. The outer wall of the material cylinder naturally forms a ring-shaped protrusion. A first spring is connected between the ring-shaped protrusion and the rotating cylinder. A positioning block is connected to one side of each material cylinder. A strip-shaped wedge block is connected to one side of the upper end of the material cylinder. The outer wall of the support frame and the inner cavity of the material cylinder are respectively provided with material conveying components for conveying solder paste.

[0007] Preferably, the material conveying assembly includes several guide grooves formed on the outer wall of the bearing sleeve, and the second output end of the dual-path cylinder is correspondingly connected to a second bracket, with two limiting blocks connected to the lower end of the second bracket.

[0008] Preferably, a transmission ring is rotatably connected between the two limiting blocks, and a plurality of round shafts are connected to the inner wall of the transmission ring corresponding to the guide groove, and the round shafts are movably inserted into the guide groove.

[0009] Preferably, the outer wall of the transmission ring is connected to a plurality of transmission rods, and the transmission rods are provided with anti-slip textures.

[0010] Preferably, the material conveying assembly further includes a storage bin and several augers, the several augers being rotatably connected inside corresponding material cylinders, and the storage bin being installed at the upper end of the bearing sleeve.

[0011] Preferably, the lower end of the material cylinder is connected to a conveying pipe corresponding to the auger, the conveying pipe is a flexible hose, and one end of the auger is rotatably connected to a first end face ratchet.

[0012] Preferably, a conical wheel is connected to one side of the first end face ratchet, the conical wheel is in contact with the outer wall of the transmission rod, and the auger is laterally slidably fitted with a second end face ratchet corresponding to the first end face ratchet, and the auger circumferentially limits the second end face ratchet.

[0013] Preferably, the first end face ratchet meshes with the second end face ratchet, and a second spring is connected between the second end face ratchet and the barrel.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves adaptive positioning of workpieces with different pipe diameters through the sliding cooperation of the conical structure of the positioning cone and multiple sets of annular array cylinders. When the positioning cone is driven down by the dual-cylinder, the strip wedge blocks drive all the cylinders to move radially synchronously, so that the positioning blocks evenly clamp the outer wall of the small pipe, ensuring the coaxiality of the large and small pipes and the consistency of the annular brazing gap under different pipe diameters. At the same time, the spiral trajectory of the guide groove drives the transmission rod to perform a combined rotation and pressing motion. Through friction, the rotating cylinder and the positioning blocks rotate synchronously around the workpiece axis, so as to achieve continuous and uniform coating of solder paste in the entire annular gap and complete the rotational feeding.

[0015] 2. This invention achieves the matching of solder paste delivery volume with the workpiece tube diameter through the conical friction transmission structure of the conical wheel and the transmission rod. When the workpiece tube diameter changes, the barrel drives the conical wheel to move radially synchronously, changing the contact diameter and transmission ratio between the conical wheel and the transmission rod, thereby adjusting the rotation speed of the auger, so that the solder paste delivery volume is adapted to the annular gap volume of different tube diameters; in conjunction with the one-way meshing structure of the first end face ratchet and the second end face ratchet, the solder paste backflow is prevented during transmission reset, ensuring the stability of solder paste delivery for workpieces with different tube diameters.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Please see Figures 1-10 The present invention provides a technical solution: an automatic feeding and positioning high-speed brazing welding machine, including a frame 1, a welding machine body 2 installed on the upper end of the frame 1, and a brazing coil 3 installed on one side of the welding machine body 2.

[0020] The large and small tubes with clearance fit are lifted to the center of the brazing coil 3 by the lifting structure to complete the initial alignment of the workpiece, so that the coaxiality of the large tube meets the pre-requirement, and waits for subsequent positioning and solder paste delivery.

[0021] In one embodiment of the present invention, a positioning calibration component is provided on the upper end of the brazing coil 3 on one side of the welding machine body 2. The positioning calibration component includes a support frame 401 installed on one side of the welding machine body 2. A dual-path cylinder 402 is installed on the upper end of the support frame 401. The first output end of the dual-path cylinder 402 is connected to a first bracket 403. The lower end of the first bracket 403 is connected to a positioning cone 404. A support sleeve 405 is connected to one side of the support frame 401. A rotating cylinder 406 is rotatably connected to the lower end of the support sleeve 405. One side of the outer wall of the rotating cylinder 406 is connected to... There is a first stop 407, and a second stop 408 is connected to the bearing sleeve 405 corresponding to the first stop 407. An arc spring 409 is connected to the side of the first stop 407 and the second stop 408 that are far apart from each other. Several material cylinders 410 are slidably connected in a ring array at the lower end of the rotating cylinder 406. The outer wall of the material cylinder 410 naturally forms an annular protrusion 411, and a first spring 412 is connected between the annular protrusion 411 and the rotating cylinder 406. A positioning block 413 is connected to one side of each material cylinder 410, and a strip wedge block 414 is connected to the upper side of the material cylinder 410. The material conveying assembly includes several guide grooves 501 provided on the outer wall of the bearing sleeve 405, and a second bracket 502 is correspondingly connected to the second output end of the dual-path cylinder 402. Two limit blocks 503 are connected to the lower end of the second bracket 502. A transmission ring 504 is rotatably connected between the two limit blocks 503. Several round shafts 505 are connected to the inner wall of the transmission ring 504 corresponding to the guide groove 501. The round shafts 505 are movably inserted into the guide groove 501. The outer wall of the transmission ring 504 is connected to several transmission rods 506, and the transmission rods 506 are provided with anti-slip textures; During positioning, the dual-path cylinder 402 is activated, and the first output end of the dual-path cylinder 402 extends downward, driving the first support 403 to press vertically downward. The first support 403 then drives the positioning cone 404 to move downward along the axis of the bearing sleeve 405. When the positioning cone 404 moves downward, its conical inner wall squeezes several strip-shaped wedges 414 arranged in a ring array. The strip-shaped wedges 414 are subjected to radially inward squeezing force, which drives the corresponding material cylinder 410 to slide from the outside to the inside along the rotating cylinder 406. When the material cylinder 410 slides inward, it drives the annular protrusion 411 integrally formed on its outer wall to move. The annular protrusion 411 compresses the first spring 412. At the same time, the material cylinder 410 drives the positioning block 413 fixedly connected to its lower end to move radially inward in sync until the inner end face of all positioning blocks 413 presses against the outer wall of the small tube. This process uses multi-point circumferential clamping to position the small tube in a clearance fit state, eliminating radial offset and wobbling between the small and large tubes, ensuring that the brazing gap between the two is uniform and consistent throughout the entire circumference, laying the foundation for subsequent brazing quality; among them, the conical structure of the positioning cone 404 can convert the vertical downward linear motion into the radial motion of multiple sets of material cylinders 410, realizing multi-point positioning driven by a single power source.

[0022] As one embodiment of the present invention, the material conveying assembly further includes a storage bin 507 and a plurality of screw conveyors 508, the plurality of screw conveyors 508 being rotatably connected to the corresponding material cylinder 410, and the storage bin 507 being installed at the upper end of the bearing sleeve 405. The outer wall of the support frame 401 and the inner cavity of the material cylinder 410 are respectively provided with material conveying components for conveying solder paste; the material conveying components include several guide grooves 501 opened on the outer wall of the support sleeve 405, the second output end of the dual-path cylinder 402 is correspondingly connected to the second bracket 502, and the lower end of the second bracket 502 is connected to two limit blocks 503. A transmission ring 504 is rotatably connected between the two limiting blocks 503. Several round shafts 505 are connected to the inner wall of the transmission ring 504 corresponding to the guide groove 501. The round shafts 505 are movably inserted into the guide groove 501. Several transmission rods 506 are connected to the outer wall of the transmission ring 504, and the transmission rods 506 are provided with anti-slip texture. The material conveying assembly also includes a storage bin 507 and several augers 508. The several augers 508 are rotatably connected to the corresponding material cylinder 410. The storage bin 507 is installed at the upper end of the bearing sleeve 405. The lower end of the material cylinder 410 is connected to the auger 508 via a material conveying pipe 509, which is a flexible hose. One end of the auger 508 is rotatably connected to a first end face ratchet 510. A conical wheel 511 is connected to one side of the first end face ratchet 510. The conical wheel 511 fits against the outer wall of the transmission rod 506. The auger 508 is laterally slidably fitted with a second end face ratchet 512 corresponding to the first end face ratchet 510, and the auger 508 circumferentially limits the second end face ratchet 512. The first end face ratchet 510 and the second end face ratchet 512 mesh, and a second spring 513 is connected between the second end face ratchet 512 and the material cylinder 410. During material feeding, as the dual-path cylinder 402 stops, its second output end extends downward, causing the second support 502 to press vertically downward. The second support 502 then drives two limiting blocks 503 to move downward. The two limiting blocks 503 drive the transmission ring 504, which is rotatably connected between them, to move vertically downward. Several round shafts 505, fixedly connected to the inner wall of the transmission ring 504, move downward synchronously with the transmission ring 504. During this downward movement, the round shafts 505 embed themselves in the guide groove 501 on the outer wall of the bearing sleeve 405 and slide along the spiral trajectory of the guide groove 501. The spiral guiding action forces the round shaft 505 to drive the transmission ring 504 to rotate circumferentially while moving vertically downward; the rotation of the transmission ring 504 in turn drives several transmission rods 506 fixedly connected to its outer wall to perform a combined rotational and downward pressing motion. The anti-slip texture on the surface of the transmission rods 506 can increase the friction coefficient with the cone wheel 511, avoid slippage during transmission, and ensure the stability of power transmission; the spiral trajectory of the guide groove 501, in conjunction with the round shaft 505, transforms the vertical linear motion of the transmission ring 504 into a combined rotational and downward pressing motion, realizing rotary material conveying without an additional power source; When the transmission rod 506 rotates and presses down, its outer wall comes into contact with the conical surface of the conical wheel 511 and generates frictional transmission, causing the conical wheel 511 to rotate around its own axis; the rotation of the conical wheel 511 in turn drives the first end face ratchet 510, which is coaxially fixedly connected, to rotate synchronously; the second spring 513 continuously applies axial thrust to the second end face ratchet 512, ensuring that the end face teeth of the first end face ratchet 510 and the second end face ratchet 512 are always tightly engaged, and the first end face ratchet 510 drives the second end face ratchet 512 through the engagement of the end face teeth. Ratchet 512 rotates; since the second end face ratchet 512 is circumferentially limited and connected to the auger 508, the second end face ratchet 512 drives the auger 508 to rotate inside the barrel 410; when the auger 508 rotates, it conveys the solder paste flowing into the inner cavity of the barrel 410 from the storage bin 507 downwards. The solder paste flows into the internal flow channel of the positioning block 413 through the flexible conveying pipe 509 at the lower end of the barrel 410, and finally flows precisely from the outlet of the positioning block 413 to the gap between the large pipe and the small pipe, thus completing the conveying of the solder paste. Among them, the anti-slip texture on the surface of the transmission rod 506 increases the contact friction with the cone wheel 511, avoids slippage during transmission, and ensures the stability of power transmission; The control of the feeding amount is as follows: When the diameter of the small tube to be welded is larger, the distance that the strip wedge block 414 drives the material cylinder 410 to move inward is smaller when the positioning cone cylinder 404 presses down for the same stroke. The distance that the cone wheel 511 moves radially with the material cylinder 410 is also smaller. At this time, the contact diameter between the transmission rod 506 and the cone surface of the cone wheel 511 is larger, the transmission ratio between the two is larger, and the speed of the cone wheel 511 is higher at the same speed of the transmission rod 506, resulting in a larger feeding amount of the auger 508. Conversely, when the diameter of the small tube is smaller, the distance that the material cylinder 410 moves inward is larger, the contact diameter between the cone wheel 511 and the transmission rod 506 is smaller, the transmission ratio is smaller, and the feeding amount of the auger 508 is smaller. This mechanism achieves the effect of adaptively matching the welding paste feeding amount according to the diameter of the workpiece tube, avoiding overflow pollution caused by too much welding paste or insufficient welding strength caused by too little welding paste. The tapered transmission surface of the cone wheel 511 can change its contact diameter with the transmission rod 506 as the material cylinder 410 moves, so that it can match the transmission ratio corresponding to different pipe diameters without the need for an additional adjustment mechanism.

[0023] Working principle: The large and small tubes with clearance fit are lifted to the center of the brazing coil 3 by the lifting structure to complete the initial alignment of the workpiece, so that the coaxiality of the large tube meets the pre-requirement, and waits for subsequent positioning and solder paste delivery. During positioning, the dual-path cylinder 402 is activated, and the first output end of the dual-path cylinder 402 extends downward, driving the first support 403 to press vertically downward. The first support 403 then drives the positioning cone 404 to move downward along the axis of the bearing sleeve 405. When the positioning cone 404 moves downward, its conical inner wall squeezes several strip-shaped wedges 414 arranged in a ring array. The strip-shaped wedges 414 are subjected to radially inward squeezing force, which drives the corresponding material cylinder 410 to slide from the outside to the inside along the rotating cylinder 406. When the material cylinder 410 slides inward, it drives the annular protrusion 411 integrally formed on its outer wall to move. The annular protrusion 411 compresses the first spring 412. At the same time, the material cylinder 410 drives the positioning block 413 fixedly connected to its lower end to move radially inward in sync until the inner end face of all positioning blocks 413 presses against the outer wall of the small tube. This process uses multi-point circumferential clamping to position the small tube in a clearance fit state, eliminating radial offset and wobbling between the small and large tubes, ensuring that the brazing gap between the two is uniform and consistent throughout the circumference, laying the foundation for subsequent high-quality brazing. During material feeding, as the dual-path cylinder 402 stops, its second output end extends downward, driving the second support 502 to press vertically downward. The second support 502 then drives the two limit blocks 503 to move downward. The two limit blocks 503 drive the transmission ring 504, which is rotatably connected between them, to move vertically downward. Several round shafts 505, which are fixedly connected to the inner wall of the transmission ring 504, move downward synchronously with the transmission ring 504. During the downward movement, the round shafts 505 are embedded in the guide grooves 501 on the outer wall of the bearing sleeve 405 and slide along the spiral trajectory of the guide grooves 501. The spiral guiding effect of the guide grooves 501 forces the round shafts 505 to drive the transmission ring 504 to rotate circumferentially while moving vertically downward. The rotation of the transmission ring 504 then drives several transmission rods 506, which are fixedly connected to its outer wall, to perform a combined rotational and downward pressing motion. The anti-slip texture on the surface of the transmission rods 506 increases the friction coefficient with the cone wheel 511, preventing slippage during transmission and ensuring the stability of power transmission. When the transmission rod 506 rotates and presses down, its outer wall comes into contact with the conical surface of the conical wheel 511 and generates frictional transmission, causing the conical wheel 511 to rotate around its own axis; the rotation of the conical wheel 511 in turn drives the first end face ratchet 510, which is coaxially fixedly connected, to rotate synchronously; the second spring 513 continuously applies axial thrust to the second end face ratchet 512, ensuring that the end face teeth of the first end face ratchet 510 and the second end face ratchet 512 are always tightly engaged, and the first end face ratchet 510 drives the second end face ratchet 512 through the engagement of the end face teeth. Ratchet 512 rotates; since the second end face ratchet 512 is circumferentially limited and connected to the auger 508, the second end face ratchet 512 drives the auger 508 to rotate inside the barrel 410; when the auger 508 rotates, it conveys the solder paste flowing into the inner cavity of the barrel 410 from the storage bin 507 downwards. The solder paste flows into the internal flow channel of the positioning block 413 through the flexible conveying pipe 509 at the lower end of the barrel 410, and finally flows precisely from the outlet of the positioning block 413 to the gap between the large pipe and the small pipe, thus completing the conveying of the solder paste. The control of the feeding amount is as follows: When the diameter of the small tube to be welded is larger, the distance that the strip wedge block 414 drives the material cylinder 410 to move inward is smaller when the positioning cone cylinder 404 presses down for the same stroke. The distance that the cone wheel 511 moves radially with the material cylinder 410 is also smaller. At this time, the contact diameter between the transmission rod 506 and the cone surface of the cone wheel 511 is larger, the transmission ratio between the two is larger, and the speed of the cone wheel 511 is higher when the transmission rod 506 rotates at the same speed, resulting in a larger feeding amount of the auger 508. Conversely, when the diameter of the small tube is smaller, the distance that the material cylinder 410 moves inward is larger, the contact diameter between the cone wheel 511 and the transmission rod 506 is smaller, the transmission ratio is smaller, and the feeding amount of the auger 508 is smaller. This mechanism achieves the effect of adaptively matching the welding paste feeding amount according to the diameter of the workpiece tube, avoiding overflow pollution caused by too much welding paste or insufficient welding strength caused by too little welding paste.
