[0028] Please see Figures 1-5 A worm grinding machine with addable gear train includes a worm grinding machine 1. The worm grinding machine 1 has a vent 26 for air circulation. A protective mesh 27 is installed inside the vent 26 for protection. A fixed rail 2 is fixedly connected to the top of the worm grinding machine 1. A gear train body 3 is installed inside the fixed rail 2. A baffle 28 is installed on the side end of the fixed rail 2 to block one end of the fixed rail 2, preventing the gear train body 3 from rolling out. The baffle 28 can be removed to facilitate the disassembly and installation of the gear train body 3. A blower 4 is installed at the bottom of the device. The air outlet of the blower 4 is connected to an air outlet pipe 5. A first fixing ring 6 is fixedly connected to the bottom outer side of the air outlet pipe 5. An adjusting pipe 7 is slidably arranged on the outside of the first fixing ring 6. A second fixing ring 8 is fixedly connected to the upper inner side of the adjusting pipe 7. The second fixing ring 8 slides with the air outlet pipe 5. A first compression spring 9 is arranged between the second fixing ring 8 and the first fixing ring 6. The first compression spring 9 is sleeved on the outside of the air outlet pipe 5. A positioning mechanism for fixing the hanging wheel body 3 is connected to the fixed rail 2.
[0029] Specifically, after the worm gear is polished, the air outlet pipe 5 and the adjusting pipe 7 are moved to the upper side of the worm gear by rolling the gear body 3 on the fixed rail 2. The adjusting pipe 7 is pulled so that its bottom end is close to the worm gear. Then, the blower 4 blows air out from inside the air outlet pipe 5 and the adjusting pipe 7. The blown air hits the worm gear and blows away the fine iron filings adsorbed on it, thus facilitating the cleaning of the fine iron filings on the worm gear and ensuring the cleanliness of the worm gear surface. After the fine iron filings on the worm gear are cleaned, the adjusting pipe 7 is released, and the first compression spring... 9. Push the second fixed ring 8 and the adjusting pipe 7 upward, so that the adjusting pipe 7 moves to the uppermost side. During the rolling process of the gear body 3 inside the fixed rail 2, avoid collision between the adjusting pipe 7 and the air outlet pipe 5 and the structure on the worm grinding machine 1. After the fine iron filings on the worm are cleaned, the gear body 3 is moved to one side by rolling inside the fixed rail 2. The gear body 3 is fixed by the positioning mechanism. During the grinding process of the worm, avoid the gear body 3 from rolling inside the fixed rail 2 and ensure the stability of the gear body 3 inside the fixed rail 2.
[0030] Please see Figure 1 , Figure 2 and Figure 5 The worm gear grinder 1 has a discharge chute 10 inside, and a suction box 11 is fixedly connected inside the discharge chute 10. Multiple suction ports 12 are evenly arranged at the top of the suction box 11. The bottom of the suction box 11 is connected to an exhaust pipe 13. The bottom of the exhaust pipe 13 is connected to a collection box 14. An exhaust fan 15 is installed on the collection box 14. A filter screen 16 is fixedly connected inside the collection box 14 near the exhaust fan 15 to facilitate the interception of fine iron filings and the collection box 14 to collect fine iron filings. A sealing plate 17 is installed at the front end of the collection box 14 to seal the opening of the collection box 14.
[0031] Specifically, during the grinding of the worm gear, the exhaust fan 15 generates a large suction force to remove the fine iron filings produced during grinding, thus preventing a large amount of fine iron filings from remaining inside the worm gear grinding machine 1. This facilitates subsequent cleaning of the worm gear grinding machine 1 and improves its practicality.
[0032] Please see Figure 1 , Figure 3 and Figure 4The positioning mechanism includes a fixed plate 18, which is fixedly connected to the fixed rail 2. A square groove 19 is provided on the fixed plate 18. A square column 20 is slidably arranged inside the square groove 19. A round plate 21 is fixedly connected to one end of the square column 20 away from the fixed rail 2. A square plate 22 is fixedly connected to one end of the square column 20. A triangular bracket 23 is fixedly connected to the side end of the square plate 22. A second compression spring 24 is provided between the square plate 22 and the fixed plate 18. The second compression spring 24 is sleeved on the outside of the square column 20. A triangular groove 25 that matches the triangular bracket 23 is provided on the side end of the gear train body 3. When the gear train body 3 moves to one end inside the worm gear grinder 1, it is convenient to fix the gear train body 3.
[0033] Specifically, when the main body 3 of the pulley moves to the position of the positioning mechanism, the side end of the main body 3 contacts the side end of the triangular bracket 23 and squeezes the triangular bracket 23, causing the second compression spring 24 to contract and the triangular bracket 23 to move to one side of the main body 3. When the main body 3 moves to one side inside the main body, the position of the triangular bracket 23 corresponds to that of the triangular slot 25. The second compression spring 24 pushes the square plate 22, the square column 20 and the triangular bracket 23 to move, so that the triangular bracket 23 is inserted into the interior of the triangular slot 25 and the main body 3 is fixed.
[0034] In summary, when using the overall equipment:
[0035] During the grinding of the worm gear, the exhaust fan 15 generates a strong suction force to remove the fine iron filings produced during grinding. After grinding, the rotating wheel 3 rolls on the fixed rail 2, moving the air outlet pipe 5 and the adjusting pipe 7 to the upper side of the worm gear. The adjusting pipe 7 is then pulled, moving its bottom end close to the worm gear. Air is then blown out from inside the air outlet pipe 5 and the adjusting pipe 7, blowing the air onto the worm gear and removing the fine iron filings. After cleaning the fine iron filings from the worm gear, the adjusting pipe 7 is released, and the first compression spring 9 pushes the second fixing ring 8 and the adjusting pipe 7 upwards, moving the adjusting pipe 7 to its uppermost position. After cleaning the fine iron filings on the worm gear, the pulley body 3 is moved to one side by rolling inside the fixed rail 2. When the pulley body 3 moves to the position of the positioning mechanism, the side end of the pulley body 3 contacts the side end of the triangular bracket 23 and squeezes the triangular bracket 23, causing the second compression spring 24 to contract and move the triangular bracket 23 to one side of the pulley body 3. When the pulley body 3 moves to one side inside the body, the position of the triangular bracket 23 corresponds to that of the triangular bracket groove 25. The second compression spring 24 pushes the square plate 22, the square column 20 and the triangular bracket 23 to move, so that the triangular bracket 23 is inserted into the interior of the triangular bracket groove 25 and the pulley body 3 is fixed.
