[0033] Please see Figure 1-6 This utility model provides a technical solution: a gear hobbing machine for easy cleaning of waste chips, including a gear hobbing machine 1, a cooling water tank 2 with a funnel shape on the surface of the gear hobbing machine 1, a waste chip cleaning device, the waste chip cleaning device being installed on the gear hobbing machine 1, the waste chip cleaning assembly including a fixed plate 21, the fixed plate 21 being fixedly connected to the inner wall of the cooling water tank 2, a fourth drive motor 22 being fixedly connected to the lower end of the fixed plate 21, a rotating shaft 24 being fixedly connected to the output end of the fourth drive motor 22, the rotating shaft 24 being rotatably connected to the fixed plate 21, three scrapers 23 being fixedly connected to the surface of the rotating shaft 24, the three scrapers 23 being arc-shaped and tangent to the surface of the rotating shaft 24, a first waste chip baffle 3 being fixedly connected to the upper end of the gear hobbing machine 1, a second waste chip baffle 4 being snapped onto the surface of the first waste chip baffle 3, a water pump 17 being fixedly connected to the upper end of the gear hobbing machine 1, and pipes 18 being fixedly connected to both the input and output ends of the water pump 17.

[0034] The upper end of the gear hobbing machine 1 is fixedly connected to a third hydraulic rod 15. The output end of the third hydraulic rod 15 is fixedly connected to an L-shaped movable frame 16. The inside of the movable frame 16 is rotatably connected to a nozzle 20. A rotary joint 19 is installed at the upper end of the nozzle 20. Multiple nozzles are fixedly connected to the lower end of the nozzle 20. Two pipes 18 extend into the interior of the gear hobbing machine 1 and are connected to the rotary joint 19, respectively. A connecting block 26 is fixedly connected to the upper end of the rotating shaft 24. A groove 25 is opened at the lower end of the nozzle 20. Both the groove 25 and the connecting block 26 are hexagonal prisms. The groove 25 and the connecting block 26 are slidably connected.

[0035] A filter plate 5 is slidably connected inside the gear hobbing machine 1. A fixed column 6 is fixedly connected to the upper end of the gear hobbing machine 1. A first hydraulic rod 8 is fixedly connected inside the fixed column 6. A guide frame 7 is fixedly connected to the output end of the first hydraulic rod 8. A first drive motor 9 is fixedly connected to the upper end of the guide frame 7. A threaded rod 10 is fixedly connected to the output end of the first drive motor 9. The threaded rod 10 is rotatably connected to the guide frame 7. A movable block 11 is threadedly sleeved on the surface of the threaded rod 10. The movable block 11 is slidably connected to the inner wall of the guide frame 7. Baffles 14 are fixedly connected to both the upper and lower ends of the movable block 11. Both baffles 14 are slidably connected to the guide frame 7 and extend out of the guide frame 7.

[0036] The front end of the movable block 11 is fixedly connected to a second drive motor 12, and the output end of the second drive motor 12 is fixedly connected to a gear hob 13, which is rotatably connected to the movable block 11.

[0037] When using this device, first fit the gear to be machined onto the surface of the rotating shaft 24, then...

[0038] The third hydraulic rod 15 is activated to lower the movable frame 16, which in turn lowers the nozzle 20, aligning the groove 25 at the lower end of the nozzle 20 with the connecting block 26. The connecting block 26 then slides on the inner wall of the groove 25, limiting the movement of the nozzle 20 and the rotating shaft 24. The second waste baffle 4 is then engaged with the surface of the first waste baffle 3. The first hydraulic rod 8 is activated to move the guide frame 7 toward the rotating shaft 24. Simultaneously, the first drive motor 9 is activated to rotate the threaded rod 10 inside the guide frame 7. The threaded rod 10 causes the movable block 11 to slide inside the guide frame 7. Because the movable block 11 is blocked by the inner wall of the guide frame 7, it can only slide inside the guide frame 7, causing the gear hob 13 on the right side of the movable block 11 to contact the gear. At the same time, the second drive motor 12 is activated to rotate the gear hob 13, and the fourth drive motor 22 is activated to rotate the rotating shaft 24 counterclockwise. The rotating shaft 24 then rotates the gear, performing gear hobbing.

[0039] Because a lot of waste chips are generated during gear hobbing, these chips easily accumulate on the surface of the hobbing machine 1, affecting gear processing and the cleanliness of the hobbing machine 1 surface. During gear hobbing, the use of the first waste chip baffle 3 and the second waste chip baffle 4 facilitates the blocking of waste chips. The presence of the first waste chip baffle 3 and the second waste chip baffle 4 concentrates the waste chips in a relatively small space, which facilitates the collection and processing of waste chips. Since waste chips can easily affect the threaded rod 10 during gear hobbing, by fixing baffles 14 at the upper and lower ends of the movable block 11, the right side of the guide frame 7 can be blocked to prevent waste chips from splashing into the interior of the guide frame 7 and affecting the threaded rod 10, thus improving the service life of the threaded rod 10. At the same time, it can assist the first waste chip baffle 3 and the second waste chip baffle 4 in blocking waste chips, improving the practicality of the device, and facilitating the concentration of waste chips inside the cooling water tank 2, which is convenient for collection by the filter plate 5.

[0040] As some debris accumulates on the surface of the fixed disk 21 during the splashing process, the rotating shaft 24 drives the scraper 23 to rotate. The rotation of the scraper 23 facilitates the scraping of debris on the surface of the fixed disk 21, which is then scraped into the cooling water tank 2 and collected by the filter plate 5.

[0041] Because heat is generated during gear hobbing using the gear hob 13, the gear hob 13 will become overheated when the heat reaches a certain level, affecting its ability to perform gear hobbing and its service life. At this point, the water pump 17 is started to draw coolant from the cooling water tank 2 through the pipe 18 to the rotary joint 19 and the spray nozzle 20, and sprays the coolant downwards through the nozzle at the lower end of the spray nozzle 20. The coolant flows on the surface of the gear. As the rotating shaft 24 rotates, it drives the connecting block 26 to rotate, which in turn drives the spray nozzle 20 to rotate. The adapter 19 ensures the continuity of coolant delivery and cooling of the gears and gear hobs 13. During the rotation of the shaft 24, the gears will rotate. Due to centrifugal force, the coolant on its surface will spread to all sides and flow out from the edge of the gears. The coolant flowing out from the edge of the gears can cool the gear hobs 13, effectively absorbing and carrying away heat, reducing the temperature of the gear hobs 13, preventing damage or reduced service life due to overheating, ensuring the normal operation of the gear hobs 13, improving the stability of the device during operation, and increasing the service life of the gear hobs 13.

[0042] As the coolant flows downward from the edge of the gear, it passes through the first waste debris baffle 3 and the cooling water tank 2, and is filtered by the filter plate 5. The design of the filter plate 5 ensures that the waste debris is blocked above the filter plate 5, while the cooling water can flow out through the filter plate 5, thus achieving separation of the two. This facilitates the reuse of the coolant and effectively avoids pollution of the environment by waste debris, protecting the ecological environment. By filtering out the waste debris using the filter plate, equipment wear can be reduced and the service life of the equipment can be extended.

[0043] Furthermore, the first waste baffle 3 and the second waste baffle 4 are designed to block the waste generated during the gear hobbing process. At the same time, the first waste baffle 3 and the second waste baffle 4 guide the waste to the interior of the filter plate 5 for easy collection. Meanwhile, the rotation of the scraper 23 can scrape the waste on the surface of the fixed plate 21, preventing the waste from accumulating on the surface of the fixed plate 21, improving the cleanliness of the gear hobbing machine 1, reducing the workload of the staff, and improving work efficiency.

[0044] The rotation of the nozzle 20 facilitates the cooling of the gear and gear hob 13, effectively absorbing and carrying away heat, reducing the temperature of the gear hob 13, preventing it from being damaged or having its service life reduced due to overheating, ensuring the normal operation of the gear hob 13, improving the stability of the device during operation, and extending the service life of the gear hob 13.

[0045] The filter plate 5 facilitates the collection of waste debris and the filtration of coolant. The design of the filter plate prevents waste debris from being blocked above the filter plate, while the cooling water can flow out through the filter plate, thus achieving the separation of the two. By using the filter plate to filter and collect waste debris, it is possible to effectively avoid the pollution of waste debris to the environment and protect the ecological environment.
