[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 6 As shown in the embodiment of this utility model, a vacuum brazing equipment for cutting teeth production includes a vacuum brazing machine 1. One side of the vacuum brazing machine 1 is provided with a door 2. A base 3 is fixedly installed on one side of the vacuum brazing machine 1. Two guide rails 4 are fixedly installed on one side of the vacuum brazing machine 1, with one side of each guide rail 4 fixedly connected to the base 3. A rectangular frame 5 is slidably connected within the two guide rails 4. An electric push rod 6 is fixedly installed within the rectangular frame 5. A fixing plate 7 is fixedly installed at the output end of the electric push rod 6, and a fixed plate 7 is fixedly installed on the top of the fixing plate 7. The system includes a servo motor 8 and a protrusion 10. A lead screw 9 is fixedly installed at the output end of the servo motor 8. One end of the lead screw 9 is connected to the protrusion 10, and a support plate 11 is movably connected to the surface of the lead screw 9. An air pump 12 is fixedly installed at the top of the rectangular frame 5. Several hollow fixed frames 13 are fixedly installed inside the rectangular frame 5. Several air outlet pipes 14 connected to the interior are fixedly installed at the bottom of the fixed frames 13. The side walls of the air outlet pipes 14 have through holes 15 connected to the interior. The fixed frames 13 and the air pump 12 are connected by pipes.

[0025] Specifically, several hollow fixed posts 16 are fixedly installed inside the rectangular frame 5. Sliding posts 17 are slidably connected inside the fixed posts 16, and the top of the sliding posts 17 is fixedly connected to the fixed plate 7. Two symmetrically arranged sliding grooves 18 are opened on the top of the fixed plate 7. Sliding sliders 19 are slidably connected inside the sliding grooves 18, and the top of the sliding sliders 19 is fixedly connected to the support plate 11.

[0026] When the pick machining in the vacuum brazing machine 1 is completed, it is necessary to note that the vacuum brazing machine 1 is internally provided with a cooling system, which is commonly an air-filled cooling system, which is prior art and will not be described in detail. The high-temperature pick is lowered to a suitable temperature (specified temperature) through the cooling system. By opening the door 2, sliding the rectangular frame 5 in the guide rail 4, moving the rectangular frame 5 to the door 2 of the vacuum brazing machine 1. Start the electric push rod 6, move the electric push rod 6 with the fixed plate 7, servo motor 8 and supporting plate 11 and other parts to the preset position, that is, the supporting plate 11 is below the tray loaded with picks, and then start the servo motor 8, move the supporting plate 11 in the vacuum brazing machine 1 through the lead screw 9, the top of the tray contacts the bottom of the tray loaded with picks, and then start the electric push rod 6 again. At this time, the servo motor 8 flips the tray loaded with picks away from the vacuum brazing machine 1, so as to return to the rectangular frame 5. Push the rectangular frame 5 to slide back to its original position. At this time, the rectangular frame 5 is no longer in front of the door 2, and the vacuum brazing machine 1 can continue to be used, while the pick tray in the rectangular frame 5 is cooled down for subsequent use. According to the actual situation, start the air pump 12 at the top of the rectangular frame 5, and the gas in the air pump 12 enters the fixed frame 13 and the air outlet pipe 14 through the pipeline and is sprayed out. At this time, start the electric push rod 6, and move the tray and the tray to the air outlet pipe 14 through the fixed plate 7, so that several flexible high-temperature-resistant air outlet pipes 14 are in the gap between several picks. Because the bottom of the pick is wider than the top (small in cross section and large in cross section), compared with the traditional air source arranged on the top or one side, the airflow speed on the top is fast and the airflow speed on the bottom is small, which causes a large temperature difference between the upper and lower positions of the pick during cooling. Therefore, the air outlet pipe 14 is inserted between the picks to fully utilize the air outlet pipe 14 and the through hole 15. The gas is sprayed out through the bottom and both sides of the through hole 15 of the air outlet pipe 14, which accelerates the airflow around the picks on the tray and speeds up the natural cooling speed of the picks, avoiding a large temperature difference caused by a sudden temperature drop, which increases the stress in the pick and causes cracks.

[0027] It should be noted that the fixed column 16 and the sliding column 17 are installed to assist the supporting plate 7 to move up and down. The sliding groove 18 and the sliding block 19 are designed to support the supporting plate 11 to prevent the supporting plate 11 from tilting after supporting the tray.

[0028] The above-mentioned mechanism realizes the pick machining after the pick is taken out, so that the staff does not need to manually take out the pick, which reduces the risk of being scalded by the staff. At the same time, the residual heat of the pick taken out can be reasonably cooled, which effectively avoids the micro cracks caused by the thermal stress of the material, which affects the service life of the pick, and does not affect the use of the vacuum brazing machine 1 during the cooling of the pick.

[0029] The inside of the sliding block 19 is provided with two symmetrically arranged receiving grooves 20, the receiving grooves 20 are clamped with the rolling ball 23, the receiving grooves 20 are slidably connected with the push plate 21 through the spring 22, one side of the push plate 21 is attached to the rolling ball 23. The air outlet pipe 14 is fixedly provided with two symmetrically arranged guide plates 24, the guide plates 24 are arc-shaped. The sliding groove 18 is fixedly provided with a rubber box 25, one side of the rubber box 25 is fixedly provided with a liquid guide pipe 26 with a one-way valve, one side of the rubber box 25 is fixedly provided with a liquid inlet pipe with a one-way valve, one end of the liquid guide pipe 26 (not fully shown) is communicated with the fixed frame 13.

[0030] When the sliding block 19 slides in the sliding groove 18, the rolling ball 23 will adhere to the inner wall of the sliding groove 18, thereby reducing the friction and facilitating the sliding of the sliding block 19. The rolling ball 23 is designed to be movable to better adapt to the sliding groove 18 and facilitate its entry into the sliding groove 18. The arc-shaped guide plate 24 in the air outlet pipe 14 is designed to guide the gas to the through hole 15, thereby facilitating the ejection of part of the gas through the through hole 15, thereby fully cooling the cutting teeth on the disc.

[0031] When the cutting teeth on the disc are cooled, the servo motor 8 continues to slide the support plate 11 and the sliding block 19 to extrude the rubber box 25, so that the maintenance liquid in the rubber box 25 enters the air outlet pipe 14 through the liquid guide pipe 26 and sprays onto the surface of the cutting teeth, thereby realizing the maintenance work of the cutting teeth. The sprayed maintenance liquid helps to maintain the material properties of the cutting teeth, avoiding the problems of strength reduction, brittleness increase and other problems caused by oxidation and decarburization.

[0032] Working principle: when the pick machining in the vacuum brazing machine 1 is completed, the rectangular frame 5 in the guide rail 4 is slid to move the rectangular frame 5 to the door 2 of the vacuum brazing machine 1. The electric push rod 6 is started to move the fixed plate 7, the servo motor 8 and the supporting plate 11 and other parts to the preset position, that is, the supporting plate 11 is below the tray loaded with picks, and then the servo motor 8 is started to move the supporting plate 11 in the vacuum brazing machine 1 through the lead screw 9, the top of the tray is in contact with the bottom of the tray loaded with picks, and the electric push rod 6 is started again, at this time the servo motor 8 turns over the tray loaded with picks to leave the vacuum brazing machine 1, so as to return to the rectangular frame 5. The rectangular frame 5 is slid to reset, at this time the rectangular frame 5 is no longer in front of the door 2, and the vacuum brazing machine 1 can continue to be used, and the tray loaded with picks is in the rectangular frame 5 for subsequent cooling. According to actual needs, the air pump 12 at the top of the rectangular frame 5 is started to make the gas in the air pump 12 enter the fixed frame 13 and the air outlet pipe 14 through the pipeline and spray out. At this time the electric push rod 6 is started to move the tray and the tray to the air outlet pipe 14 through the fixed plate 7, so that the plurality of flexible high-temperature-resistant air outlet pipes 14 are in the gaps of the plurality of picks, at this time the gas is sprayed out through the bottom and the through holes 15 on both sides of the air outlet pipe 14, so as to realize omnidirectional cooling of the picks on the tray.

[0033] When the picks on the tray are cooled, the servo motor 8 continues to slide and extrude the rubber box 25 with the supporting plate 11 and the sliding block 19, so that the maintenance liquid in the rubber box 25 enters the air outlet pipe 14 through the liquid guide pipe 26 and sprays to the surface of the picks.
