[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Depend on Figures 1 to 2 As shown, this utility model embodiment provides a plastic gear oiling device, including a control console 1, an oiling component 2, and a gear positioning component 3, which are respectively disposed on the control console 1. The gear positioning component 3 includes a first drive motor 4, a turntable 5, a second drive motor 6, and a placement platform 7. The first drive motor 4 is connected to the turntable 5. Multiple placement platforms 7 are provided and arranged circumferentially on the turntable 5. In this embodiment, three placement platforms 7 are provided and evenly spaced circumferentially on the turntable 5. A positioning pin 8 is coaxially protruding from the upper end of the placement platform 7. The positioning pin 8 passes through the shaft hole of the plastic gear 9 for coaxial positioning of the plastic gear 9. In a preferred embodiment, the positioning pin 8 and the placement platform 7 are connected by a threaded connection, allowing for the removal and replacement of positioning pins 8 of different diameters to match and install plastic gears 9 with different hole sizes.

[0019] The second drive motor 6 is connected to the placement platform 7. The output end of the oiling component 2 faces the axis of the turntable 5 and is located on the same horizontal plane as the plastic gear 9 on the placement platform 7, so as to apply oil to the plastic gear 9 on the placement platform 7. The control console 1 is electrically connected to the oiling component 2 and the gear positioning component 3 for control. The first drive motor 4 drives the turntable 5 to rotate, so that the placement platforms 7 on the turntable 5 can rotate one by one to the front of the output end of the oiling component 2. At the same time, the second drive motor 6 drives the placement platform 7 to rotate, so that the oiling component 2 applies oil to the outer circumference of the plastic gear 9 mounted on the placement platform 7. The oiling process is automated, the oil is applied evenly, which is very convenient and can also avoid the impact of oil on the skin health of the hands when applying oil manually.

[0020] Preferably, the grease application assembly 2 includes a third drive motor 10, a lead screw and slide rail assembly 11, and a high-pressure precision switching valve 12. The third drive motor 10 is connected to the lead screw and slide rail assembly 11. The high-pressure precision switching valve 12 is installed on the upper end of the slider of the lead screw and slide rail assembly 11, and an grease nozzle 13 is provided on the side of the high-pressure precision switching valve 12 near the turntable 5. The third drive motor 10 drives and controls the lead screw and slide rail assembly 11, causing its slider to move the high-pressure precision switching valve 12 closer to or away from the turntable 5, thereby adjusting the position of the grease nozzle 13 for different sizes of plastic gears 9. An external air pump pipeline (not shown in the figure) controls the movement of the piston at the input end of the high-pressure precision switching valve 12, thereby pushing the oil in the internal oil storage chamber to be discharged from the grease nozzle 13 for grease application, and it can also be drawn back. The port of the grease nozzle 13 is angled upwards, so that when the grease flows out, its own viscous tension prevents it from dripping, and when it approaches the edge of the plastic gear 9, the grease can be applied to the plastic gear 9. Therefore, there is a gap between the end of the oil nozzle 13 and the plastic gear 9 during oil filling, so they do not need to be in direct contact.

[0021] Preferably, the turntable 5 is arranged in a double-layered structure, including a lower plate 14, an upper plate 15, and multiple columns supporting and connecting the two, so that there is space inside the turntable 5; further, the second drive motor 6 is fixed at the upper end of the upper plate 15, and the output shaft extends into the space of the turntable 5. At the same time, a first synchronous pulley 17 is connected to the output shaft. A connecting shaft is connected to the lower end of the placement platform 7. A second synchronous pulley 18 is coaxially arranged on the connecting shaft. The first synchronous pulley 17 and the second synchronous pulley 18 are connected by a synchronous belt 19. The connecting shaft can rotate relative to the turntable 5, thereby driving the placement platform 7 to rotate.

[0022] Preferably, a reducer 20 is provided between the first drive motor 4 and the turntable 5. After the first drive motor 4 is reduced in speed by the reducer 20, it drives the turntable 5 to rotate, which is more stable.

[0023] Preferably, the placement platform 7 is located at the edge of the turntable 5. This allows the edge of the placement platform 7 to extend beyond the turntable 5, facilitating the oiling assembly 2 to oil the plastic gear 9 placed on it.

[0024] In one preferred embodiment, after installing plastic gears 9 on the three placement platforms 7 on the turntable 5, the control console 1 drives the first drive motor 4 to rotate the turntable 5, bringing the first placement platform 7 close to the oil nozzle 13. Then, the turntable 5 stops rotating, and the second drive motor 6 drives the turntable 5 to rotate, applying oil to its outer circumference using the oil nozzle 13. After application, the turntable 5 rotates again, bringing the next placement platform 7 close to the oil nozzle 13, thus continuing the oiling process. In another embodiment, loading and unloading positions can be provided to create a continuous production line for oiling the plastic gears 9.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
