The oiling holes in workshop gearboxes are of different sizes, the operating space is narrow, the connection between the oiling device and the oiling hole is difficult, the oiling operation is inconvenient, the gear oil is easy to spill, resulting in waste and increased costs. In the case of high viscosity lubricating oil or low temperature, the small oiling hole is easy to be blocked, resulting in low oiling efficiency.

The magnetic base facilitates adsorption and fixation, and the connection and disassembly are convenient. The position and angle of the oil filling nozzle are easy to adjust, and the stability is high.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a pneumatic gear oiling device, including a cylinder barrel 1; it also includes an oiling cylinder 9 and a magnetic seat 13. A piston 2 is slidably connected inside the cylinder barrel 1, and a sealing block 3 is provided inside the piston 2. A front end cover 4 and a rear end cover 5 are fixedly connected to the left and right ends of the cylinder barrel 1. An air filter 6 is fixedly connected to the upper end of the rear end cover 5, and an oil filter 7 is provided at the left end of the front end cover 4. An oil outlet pipe 8 is fixedly connected to the upper end of the front end cover 4, and an oiling cylinder 9 is fixedly connected to the end of the oil outlet pipe 8 away from the front end cover 4. A large oiling nozzle 10 is fixedly connected to the front end of the oiling cylinder 9, and a small oiling nozzle 11 is threaded to the front end of the large oiling nozzle 10. A heating cylinder 12 is fixedly connected to the outside of the oiling cylinder 9, and a magnetic seat 13 is provided at the lower end of the heating cylinder 12. The left side of the upper end of the cylinder barrel 1... The controller 14 is fixedly connected. During use, the magnetic base 13 is attached to the surface of the gearbox or a convenient location. Depending on the size of the oil filling hole, the small oil filling nozzle 11 is installed, and the position and angle of the large oil filling nozzle 10 are adjusted to align with the oil filling hole to avoid oil splashing and waste. The connection and disassembly are convenient and the stability is high. Gear oil is slowly added to the cylinder barrel 1 through the oil filter 7 to complete the oil storage. Compressed air enters the cylinder barrel 1 through the air filter 6, pushing the piston 2 to move to the left to squeeze. The gear oil is injected into the gearbox from the oil outlet pipe 8 through the oil filling cylinder 9, the large oil filling nozzle 10, and the small oil filling nozzle 11. The piston 2 moves to precisely control the oil, and the gear oil in the pipe is heated by the heating cylinder 12 to adapt to oils of different viscosities and different working environments, reducing viscosity, increasing fluidity, and improving oil filling efficiency and effect.

[0023] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the sealing block 3 is made of oil-resistant rubber. The piston 2 and the sealing block 3 are bonded together with sealant. The cylinder rod on the piston 2 is removed, and the sealing block 3 is bonded to improve the sealing performance and prevent gear oil leakage. The left end of the front cover 4 is threaded with a threaded connection to a pair of threads 15. The left end of the pair of threads 15 is threaded with an oil inlet valve 16. The left end of the oil inlet valve 16 is fixedly connected to the oil filter 7. The left end of the oil filter 7 is connected to an external oil pipe. When the oil inlet valve 16 is opened, the filtered gear oil flows into the front cover 4 through the pair of threads 15. The oil filter 7 effectively filters impurities in the gear oil, ensuring the cleanliness of the oil and protecting mechanical parts such as gears. After the oil is filled, the oil inlet valve 16 is closed. The upper end of the air filter 6 is fixedly connected to the air inlet valve 17. The front end of the air inlet valve 17 is connected to the external compressed air pipe. The air inlet valve 17 is electrically connected to the controller 14. When the air inlet valve 17 is opened, the filtered compressed air enters the cylinder barrel 1, and the piston 2 moves to precisely control the oil. The air filter 6 effectively removes dust and moisture from the compressed air, avoiding wear on parts.

[0024] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the oil outlet pipe 8 is made of PU material, and the heating cylinder 12 is made of heating element material. The heating cylinder 12 is electrically connected to the controller 14. The controller 14 controls the heating cylinder 12 to heat the gear oil in the pipe, adapting to oils of different viscosities and different working environments, preventing the oil from solidifying and clogging the pipe, improving the operating efficiency of the equipment, and reducing wear and energy consumption caused by excessively high oil viscosity. The upper end of the magnetic seat 13 is fixedly connected to the support seat 18, and the upper end of the support seat 18 is threadedly connected to the adjustment seat 19. The height of the support seat 18 and the adjustment seat 19 is adjusted. The upper end of the adjustment seat 19 is fixedly connected to the connecting seat 20. The upper end of the connecting seat 20 is rotatably connected to the outside of the heating cylinder 12 through a damping shaft. Rotating the connecting seat 20 adjusts the tilt angle of the oil injection nozzle, so that the gear oil is injected into the gearbox at a suitable pressure and angle, achieving good oil coverage and penetration.

[0025] During operation, the magnetic base 13 is attached to the surface of the gearbox or a convenient location. Depending on the size of the oil filling hole, the small oil filling nozzle 11 is installed, and the position and angle of the large oil filling nozzle 10 are adjusted to align with the oil filling hole. The oil inlet valve 16 is opened, and gear oil is slowly added to the cylinder barrel 1 through the oil filter 7 to complete the oil storage. The air inlet valve 17 is opened, and compressed air enters the cylinder barrel 1 through the air filter 6, pushing the piston 2 to move to the left and squeeze. Gear oil is injected into the gearbox from the oil outlet pipe 8 through the oil filling cylinder 9, the large oil filling nozzle 10, and the small oil filling nozzle 11. The piston 2 moves to precisely control the oil, and the gear oil in the pipe is heated by the heating cylinder 12, which improves the oil injection efficiency and effect.

[0026] Through the above steps, the use of the oil filling cylinder 9 and the magnetic seat 13 makes it easy to attach and fix the oil, and the position and angle of the oil filling nozzle are easy to adjust. The connection and disassembly are convenient and the stability is high. The heating cylinder 12 heats the gear oil, which has wide adaptability, increases fluidity, and improves the oil filling efficiency and effect. This solves the problems of difficult connection between the existing oil filling device and the oil filling hole, inconvenient operation, easy spillage of gear oil, and low oil filling efficiency.
