[0017] In the embodiments, the technical solutions of the present application will be clearly and completely described in conjunction with the accompanying drawings of the specification. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0018] Embodiment 1: The present invention provides a carbide tool automatic continuous brazing device. Please refer to Figure 1 - Figure 13 , which includes a frame 1 and a leveling substrate 2 arranged on the frame 1. A clamping mechanism 6 for clamping and driving the tool body 9 to rotate at equal angles is provided on the leveling substrate 2. To further improve the loading efficiency of the tool body 9 to be brazed, a manipulator can be used to perform the loading and unloading operations of the tool body 9 for the clamping mechanism 6. A feeding mechanism 5 for providing the tool tip 93 for the tool body 9 is also provided on the frame 1. A number of equally spaced assembly notches 92 are provided on the tool body 9. Before the tool body 9 undergoes brazing operation, a cleaning operation is required, especially paying attention to cleaning the surface oil, oxides and other impurities at the assembly notches 92. The tool tip 93 is coated with brazing solder through the feeding mechanism 5 and placed in the assembly notch 92. It should be noted that in this embodiment, the brazing solder is a copper-based brazing solder with a melting point of 900 - 1200 °C; On one side of the clamping mechanism 6, an inductive coil 8 for heating the assembly notch 92 coated with brazing solder is provided. At the same time, the inductive coil 8 is also used to preheat the vacant assembly notch 92 to reduce the overall deformation of the tool body 9 caused by thermal stress. An air purification mechanism 3 for adsorbing brazing exhaust gas is also provided on the frame 1 to reduce the harm caused by the harmful gases generated during brazing to the human body and the environment. The leveling substrate 2 is used to adjust the levelness of the assembly notch 92 located at the inductive coil 8.

[0019] Please refer to Figure 3 - Figure 4, a ball head seat 22 is fixed on one side of the bottom of the leveling substrate 2. A ball head matching the ball head seat 22 is arranged in the frame 1. On the other side of the bottom of the leveling substrate 2, there are two groups of symmetrically arranged leveling cylinders 21. Both ends of the leveling cylinder 21 are rotatably connected to the leveling substrate 2 and the frame 1 respectively. A level sensor for detecting the levelness is also arranged on the leveling substrate 2.

[0020] Specifically, the leveling substrate 2 is mainly used to adjust the levelness of the assembly notch 92 in the inductor coil 8, so that the contact surface between the assembly notch 92 and the tool bit 93 is kept horizontal. Then, after the brazing solder smeared on the tool bit 93 is melted, it can evenly fill the gap between the assembly notch 92 and the tool bit 93 to form a uniformly distributed bonding layer, thereby improving the quality of the welded joint and the service life of the tool body 9.

[0021] It should be noted that the level sensor is used to detect the levelness of the assembly notch 92 in the inductor coil 8. The levelness of the leveling substrate 2 is adjusted by adjusting the telescopic amount of the two groups of leveling cylinders 21 to finally keep the assembly notch 92 in the inductor coil 8 in a horizontal state.

[0022] Please refer to Figure 5 , wherein, the clamping mechanism 6 includes a rotating seat 61 rotatably connected to the leveling substrate 2. A three-jaw chuck 62 is fixed on one side of the rotating seat 61. A shaft hole 91 matching the three-jaw chuck 62 is arranged on the tool body 9; a driving mechanism 7 is also arranged on one side of the rotating seat 61. The driving mechanism 7 includes a driving motor 71 fixed on the rotating seat 61. A pulley 72 is fixed on the output end of the driving motor 71. The pulley 72 and the rotating seat 61 are driven by a belt. The driving motor 71 is used to drive the rotating seat 61 to perform an equal-angle rotation action. Specifically, the rotation angle of the rotating seat 61 is equal to the arrangement angle of adjacent assembly notches 92 on the tool body 9.

[0023] Spacing sensors 63 are symmetrically fixed on both sides of the three-jaw chuck 62 on the rotating seat 61. The spacing sensors 63 are used to detect the diameter data of the tool body 9 clamped by the three-jaw chuck 62. A pushing cylinder 81 is also arranged on the rotating seat 61. The displacement direction of the pushing cylinder 81 is the radial direction of the tool body 9 installed on the three-jaw chuck 62. The inductor coil 8 is fixed on the output end of the pushing cylinder 81. An adjusting cylinder 4 is also fixed on the frame 1. The feeding mechanism 5 is fixed on the output end of the adjusting cylinder 4.

[0024] When the spacing sensors 63 detect the diameter data of the tool body 9 clamped by the three-jaw chuck 62, the data is fed back to the control unit, and the control unit synchronously adjusts the displacement data of the pushing cylinder 81 and the adjusting cylinder 4, so that the inductor coil 8 and the feeding mechanism 5 are respectively attached to the side of the tool body 9 to meet the brazing requirements of the tool body 9 with different diameter sizes and improve the adaptability of brazing.

[0025] Please refer to Figure 6 - Figure 8 , the feeding mechanism 5 includes a feeding base 51. A storage groove 511 for storing the cutter head 93 is provided at the top of the feeding base 51. A pushing slide 52 is slidably connected to the bottom of the storage groove 511. A pushing spring 521 is fixed between the pushing slide 52 and the feeding base 51; One end of the storage groove 511 is provided with a feeding chute 512 communicating with it. The cutter heads 93 in the feeding chute 512 and the storage groove 511 are both inclined. One side of the pushing slide 52 in contact with the cutter head 93 is provided with an inclination corresponding to the cutter head 93. To reduce the feeding friction of the cutter head 93 in the storage groove 511, a ceramic guide rail is provided in the storage groove 511. Further, when the leveling substrate 2 adjusts the assembly notch 92 in the inductor coil 8 to be in a horizontal state, the inclination of the assembly notch 92 at the bottom of the feeding mechanism 5 is the same as and oppositely arranged to the inclination of the feeding chute 512. The pushing spring 521 has an elastic force to drive the pushing slide 52 to approach the feeding chute 512, so as to push the cutter head 93 into the feeding chute 512. A cutting mechanism 53 for pushing the cutter head 93 to move downward is provided on the feeding chute 512, so as to push the cutter head 93 to move downward into the assembly notch 92. The adjusting cylinder 4 is specifically used to adjust the distance between the output end of the feeding chute 512 and the tool body 9.

[0026] Please refer to Figure 8 - Figure 13 , it should be noted that, in this embodiment, the cutting mechanism 53 includes a turning plate 532 rotatably connected. Two groups of symmetrically arranged arc-shaped chutes 513 are provided on the outer wall of the feeding base 51. A reset tension spring 533 is fixed between one side of the turning plate 532 and the arc-shaped chute 513. Two groups of transmission force arms 531 are symmetrically and rotatably connected to the other side of the turning plate 532. A cutting slide 534 is slidably connected in the feeding chute 512. The ends of the transmission force arms 531 away from the turning plate 532 are respectively rotatably connected to one side of the top of the cutting slide 534.

[0027] The reset tension spring 533 has an elastic force to drive the turning plate 532 to turn downward and away from the output end of the feeding chute 512. The adjusting cylinder 4 drives the feeding mechanism 5 to move downward and keeps the output end of the feeding chute 512 tangent to the top of the tool body 9.

[0028] During the process of the three-jaw fixture 62 clamping the tool body 9 for an equiangular rotation action, when the assembly notch 92 at the top of the tool body 9 has not rotated below the output end of the feeding chute 512, the turning plate 532 is resisted by the side of the tool body 9, causing the turning plate 532 to overcome the elastic force of the return spring 533 and turn close to the output end of the feeding chute 512. On the one hand, the turning plate 532 blocks the output end of the feeding chute 512, making it difficult for the tool tips 93 in the feeding chute 512 to fall off. On the other hand, through the upward turning of the turning plate 532 close to the feeding chute 512, the transmission lever arm 531 is used to drive the cutting material slide plate 534 to move upward, and then the tool tips 93 squeezed by the pushing slide base 52 in the storage chute 511 are pushed into the feeding chute 512 to complete the feeding action of the tool tips 93.

[0029] When the assembly notch 92 at the top of the tool body 9 rotates below the output end of the feeding chute 512, the bottom end of the turning plate 532 slides into the assembly notch 92. At this time, the turning plate 532 is no longer resisted by the side of the tool body 9. Under the elastic force of the return spring 533, the turning plate 532 makes a turning action away from the output end of the feeding chute 512. On the one hand, the output end of the feeding chute 512 is opened, and the output end of the feeding chute 512 is aligned with the assembly notch 92 at the top of the tool body 9. On the other hand, through the downward turning of the turning plate 532 away from the feeding chute 512, the transmission lever arm 531 is used to drive the cutting material slide plate 534 to move downward, and then the tool tips 93 pushed into the feeding chute 512 are moved downward, so that the tool tips 93 are pushed into the assembly notch 92 at the top of the tool body 9 to complete the assembly action of the tool tips 93 and the assembly notch 92.

[0030] After completing the assembly action of the tool tips 93 and the assembly notch 92, the three-jaw fixture 62 continues to drive the tool body 9 for an equiangular rotation action, causing the side of the tool body 9 to resist the turning plate 532 again, making the turning plate 532 turn upward again against the elastic force of the return spring 533 to block the output end of the feeding chute 512 and perform the next cycle of feeding action, thereby realizing the continuous cyclic brazing operation of the tool tips 93 on the tool body 9.

[0031] Furthermore, please refer to Figure 13 , a brazing material conduit 514 is further provided on the feeding base 51. The output end of the brazing material conduit 514 is provided with a number of horizontally and equidistantly arranged brazing material nozzles 515. The brazing material nozzles 515 are arranged in the feeding chute 512. A flexible scraper 54 is fixed at the bottom of the brazing material nozzle 515 in the feeding chute 512. The height of the flexible scraper 54 is lower than the bottom height of the storage chute 511. An anti-overflow baffle 535 is fixed on the side of the turning plate 532 away from the return spring 533. The anti-overflow baffle 535 is arranged perpendicular to the turning plate 532.

[0032] When the turning plate 532 turns downward, the solder conduit 514 starts to supply the flowing soldering flux to the solder nozzle 515. Under the pushing action of the cutting slide plate 534, the cutting head 93 in the feeding chute 512 moves downward, so that the side of the cutting head 93 to be welded to the assembly notch 92 is sprayed with uniform soldering flux. The flexible squeegee 54 is used to scrape and keep the thickness of the soldering flux on the cutting head 93 uniform. The flexible squeegee 54 will collect the residual soldering flux from the previous process. On the one hand, it prevents the soldering flux from falling and causing pollution. On the other hand, it also coats the bottom of the cutting head 93 with soldering flux, further improving the uniformity of the coating of the soldering flux. At the same time, with the setting of the anti-overflow baffle 535, when the turning plate 532 completely turns away from the output end of the feeding chute 512, the downward movement of the cutting head 93 is limited, preventing the cutting head 93 from falling off after moving downward. At the same time, it also prevents the soldering flux between the cutting head 93 and the assembly notch 92 from overflowing after they are aligned, further improving the soldering quality.

[0033] Through the mutual cooperation between the feeding mechanism 5 with the cutting mechanism 53 and the storage tank 511 and the clamping mechanism 6 with the three-jaw clamp 62 and the induction coil 8, the present application can realize the automatic feeding of the cutting head 93 for the tool body 9. During the feeding process of the cutting head 93, the soldering flux is evenly applied. The levelness between the assembly notch 92 and the cutting head 93 is adjusted at the induction coil 8, so that the soldering flux maintains a uniform distribution state during the heating and melting process, in order to improve the soldering quality of the tool body 9. The soldering efficiency is high, continuous operation is possible, it has a market prospect and is suitable for popularization and application.

[0034] The above is only the best implementation mode adopted by the present application in combination with the current actual needs, but the protection scope of the present application is not limited thereto.
