Then, the support chassis 41 is rotated to allow the limit ring 45 to slide out of the mounting groove 32. The side of the limit ring 45 away from the branch pipe 44 is fixedly connected to the bottom of the support chassis 41. The side of the branch pipe 44 away from the limit ring 45 is fixedly connected to the outer wall of the mounting pipe 46.

[0021] Working principle:
[0022] The automatic grease injection machine is mainly composed of an oil barrel 1, an integrated device 2 and other parts. The oil barrel 1 serves as a storage container for grease. The top of the oil barrel 1 is fixedly connected to an oil pump 5. The output end of the oil pump 5 is connected to an oil pipe 6. A clamp 7 is also clamped on the oil pipe 6 to ensure that the connection of the oil pipe 6 is firm.
[0023] The integrated device 2 is a key part for realizing automatic greasing of the slewing bearing. It includes a limit assembly 3 and a pumping assembly 4. The bottom of the limit assembly 3 is fixedly connected to the top of the oil barrel 1, and is mainly used to limit the position of the slewing bearing. The mounting ring 31 in the limit assembly 3 is slidably connected to the slide rod 34 through the fixed ring 33. The counterweight ball 36 at the bottom of the slide rod 34 can play a role in stabilizing the structure. The top of the slide rod 34 is connected to the soft frame 35, which can adapt to slewing bearings of different sizes to a certain extent and provide a certain buffer. The support rod 37 on the inner wall of the mounting ring 31 is slidably connected to the support ring 38 through the slider 39, and the bottom of the support ring 38 is fixedly connected to the top of the oil barrel 1. This structure enables the limit assembly 3 to adjust its position within a certain range to better adapt to slewing bearings of different specifications.
[0024] During actual use, first grasp the handle on the top of the soft frame 35 and slide it upward so that the soft frame 35 does not block the slewing bearing from being placed on the pumping assembly 4. After the slewing bearing is placed, release the handle tension, and the counterweight ball 36 at the bottom of the slide rod 34 drives the slide rod 34 to slide downward under the action of gravity, so that the soft pad presses on the slewing bearing to limit its position. If you need to disassemble the limit assembly 3, grasp the support rod 37 and make the slider 39 at the bottom of the support rod 37 slide out of the groove in the support ring 38, and then you can remove the mounting ring 31.
[0025] The pumping assembly 4 is used to pump the grease in the oil barrel 1. It includes a supporting chassis 41. Grease nozzles 42 are distributed in a circular array on the top inner wall of the supporting chassis 41 to ensure that the grease is evenly distributed inside the bearing. The fixing frame 43 on the outer wall of the supporting chassis 41 is connected to the mounting pipe 46 through a branch pipe 44. The mounting pipe 46 is sleeved with the oil pipe 6, so that the grease extracted from the oil barrel 1 can be smoothly transported to the branch pipe 44 and the grease nozzle 42. The limiting ring 45 on the branch pipe 44 is fixedly connected to the bottom of the supporting chassis 41 on the one hand to enhance the structural stability. On the other hand, it is connected to the limiting assembly 3 through the mounting groove 32 on the mounting ring 31 to ensure that the position of the pumping assembly 4 is stable during operation.
[0026] When the pumping assembly 4 is working, the oil pump 5 is first started to transport the grease in the oil barrel 1 to the mounting pipe 46 and the branch pipe 44 through the oil pipe 6, and finally sprayed out from the grease injection nozzle 42 to automatically inject grease into the slewing bearing. When the size of the pumping assembly 4 does not match the slewing bearing, the branch pipe 44 is first removed from the limit ring 45 to separate the branch pipe 44 from the limit ring 45, and then the support chassis 41 is rotated to allow the limit ring 45 to slide out of the mounting groove 32, and the support chassis 41 can be slid out and replaced with the support chassis 41 that matches the slewing bearing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention.
