[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a waste chip recycling device for a worm gear polishing machine, including a base plate 1. The base plate 1 includes a recycling mechanism 3 for recycling waste chips. A recycling trough 31 is provided on one side of the top of the base plate 1. An installation groove 32 is provided on the bottom wall of the recycling trough 31. An air conveying groove 33 is provided on the inner wall of the installation groove 32. A hose 9 is fixedly connected to one end of the air conveying groove 33. A nozzle 10 is fixedly connected to one end of the hose 9. A fine-pore filter plate 36 is fixedly installed in the middle of the inner wall of the recycling trough 31. A coarse-pore filter plate 37 is fixedly installed in the upper part of the inner wall of the recycling trough 31. A fan 35 is fixedly installed on the top of the inner wall of the mounting slot 32. A rotating column 38 is fixedly sleeved inside the fan 35. A first scraper 39 is fixedly connected to the upper surface of the rotating column 38. The lower surface of the first scraper 39 is in contact with the upper surface of the coarse pore filter plate 37. A second scraper 310 is fixedly connected to the middle surface of the rotating column 38. The lower surface of the second scraper 310 is in contact with the upper surface of the fine pore filter plate 36. The base plate 1 has two collection slots 34 inside, and the interior of both collection slots 34 is connected to the interior of the recycling slot 31. The inner walls of the two collection slots 34 are slidably connected to the same double-layer waste drawer 311.

[0018] During use, the blower 35 starts to generate airflow, which enters the hose 9 through the air delivery channel 33 on the inner wall of the mounting slot 32, and finally sprays out from the nozzle 10, blowing the scattered waste into the recycling tank 31 to complete the initial guidance and collection of waste. The waste entering the recycling tank 31 first contacts the upper coarse-pore filter plate 37. The coarse-pore filter plate 37 has a larger pore size, which can intercept larger metal chips and only allow fine powder and airflow to pass through. The fine waste and airflow passing through the coarse-pore filter plate 37 continue downward and contact the middle fine-pore filter plate 36. The fine-pore filter plate 36 has a smaller pore size, which can intercept fine powder. The airflow then passes through the fine-pore filter plate 36 and enters the lower mounting tank 32. When the fan 35 is running, the rotating column 38 inside it rotates synchronously, driving the first scraper 39 and the second scraper 310 connected to the surface to rotate. When the first scraper 39 rotates, it can scrape off the coarse debris accumulated on the coarse pore filter plate 37 to prevent the coarse pores from being blocked. When the second scraper 310 rotates, it can scrape off the fine powder accumulated on the fine pore filter plate 36 to prevent the fine pores from being blocked, thus ensuring normal airflow. The scraped-off coarse chips and fine powder slide into the collection tank 34, and finally the waste chips enter the double-layer waste chip drawer 311. The double-layer waste chip drawer 311 can store coarse chips and fine powder separately, and can be directly pulled out for waste chip cleaning or recycling later. When the blower 35 is started, the airflow passes through the air duct 33 and the hose 9 and is sprayed from the nozzle 10, blowing the waste into the recycling tank 31, completing the initial guidance and collection of the waste. The waste is filtered by the coarse-pore filter plate 37 and the fine-pore filter plate 36 respectively, and the airflow enters the installation tank 32 to form a circulation. At the same time, the blower 35 drives the rotating column 38 and the first scraper 39 and the second scraper 310 to rotate, cleaning the coarse-pore filter plate 37 and the fine-pore filter plate 36 respectively to prevent clogging. Finally, the waste enters the double-layer waste drawer 311 for classified storage, which facilitates subsequent cleaning and recycling, thereby achieving the purpose of efficient waste recycling, improving resource utilization, and reducing the impact of waste on the health of operators.

[0019] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a linear guide rail assembly 4 is provided on the other side of the top of the base plate 1, a movable seat 5 is slidably connected to the top of the linear guide rail assembly 4, a fixed column 51 is fixedly connected to one corner of the top of the movable seat 5, a fixed plate 52 is fixedly connected to one side of the movable seat 5, and a bracket 6 is rotatably connected to the surface of the fixed column 51. The bracket 6 includes a swing mechanism 7 for swing grinding and a grinding mechanism 8 for grinding. A cylinder 71 is fixedly installed on one side of the top of the bracket 6 via a mounting bracket. The telescopic shaft of the cylinder 71 is rotatably connected to a U-shaped seat 72. A linkage rod 73 is movably connected to the inner wall of the U-shaped seat 72. One end of the linkage rod 73 is movably connected to a connecting seat 74. One end of the connecting seat 74 is rotatably connected to one side of the fixed plate 52.

[0020] During use, the linear guide rail assembly 4 can enable the movable seat 5 to drive the bracket 6 and related mechanisms to slide horizontally along the linear guide rail assembly 4, thereby adjusting the horizontal position. When the telescopic shaft of cylinder 71 extends or retracts, it will drive the U-shaped seat 72 to move. The U-shaped seat 72 will drive the linkage rod 73 to move. One end of the connecting seat 74 will rotate on one side of the fixed plate 52 and the position will be relatively fixed. Under the drive of the linkage rod 73, the bracket 6 will swing back and forth around the fixed column 51 as the fulcrum, thereby driving the grinding mechanism 8 on the bracket 6 to realize the swing grinding action, so that the grinding is more uniform and comprehensive. This design, through the setting of the swing mechanism 7, enables the grinding mechanism 8 to swing back and forth. Compared with fixed-angle grinding, it allows the polishing tool to make more uniform contact with the worm surface, avoiding local over-polishing or under-polishing, and is especially suitable for polishing complex curved surfaces such as worms.

[0021] Reference Figures 1-5 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a motor 81 is fixedly installed on the other side of the top of the bracket 6 by a mounting bracket. The output shaft of the motor 81 passes through one side of the bracket 6 and is fixedly sleeved with a first rotating wheel 82. An adjusting rod 83 is rotatably connected to the top of one side of the bracket 6. One end of the adjusting rod 83 is fixedly connected to a mounting base 84. A second rotating wheel 85 is rotatably connected to one side of the mounting base 84. The surfaces of the first rotating wheel 82 and the second rotating wheel 85 are provided with the same sanding belt 86. A fixed rod 87 is fixedly connected to one side of the bracket 6, and an electric push rod 88 is rotatably connected to one side of the fixed rod 87. One end of the telescopic shaft of the electric push rod 88 is rotatably connected to one end of the adjusting rod 83. A clamping assembly 2 is provided on one side of the top of the base plate 1. The clamping assembly 2 includes a three-jaw chuck 21 and a fixing seat 22.

[0022] During use, the motor 81 is started, and its output shaft drives the first rotating wheel 82 to rotate. Through the friction of the sanding belt 86, the second rotating wheel 85 rotates synchronously. At this time, a high-speed moving polishing surface is formed on the surface of the sanding belt 86. When the electric push rod 88 extends, it pushes the adjusting rod 83 to rotate around the connection point with the bracket 6, causing the second rotating wheel 85 to move away from the first rotating wheel 82, and the tension of the sanding belt 86 increases. When the electric push rod 88 shortens, the adjusting rod 83 rotates in the opposite direction, and the second rotating wheel 85 moves closer to the first rotating wheel 82, and the tension of the sanding belt 86 decreases. This can adapt to worm gear polishing of different materials and hardness, and improve the polishing quality.

[0023] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
