A support leg 14 is fixedly installed on the top of the support platform 1. An oil reservoir 15 is fixedly installed at the end of the support leg 14 away from the support platform 1. A plastic clip 16 is fixedly installed on the left side of the oil reservoir 15. A movable cover 17 is detachably connected to the top of the oil reservoir 15. The PLC controller 11 is an existing device. The controller 11 is used to control the operation of the metering pump 21 and the heating rod 34. The design of the casters 12 and the push-pull bracket 13 makes it easy for users to move this structure. The support leg 14 is used to raise and support the oil reservoir 15. The plastic clip 16 is used to secure the handle tube 26 for easy storage and organization. The movable cover 17 is connected to the oil reservoir 15 by threads. The movable cover 17 can be rotated out from the top of the oil reservoir 15, and then lubricating oil can be filled into the inner cavity of the oil reservoir 15.

[0034] As one implementation method in this embodiment, such as Figure 2 As shown, the metering filling mechanism 2 includes a metering pump 21, which is fixedly installed on the top of the support platform 1. The input pipe of the metering pump 21 is fixedly connected to the bottom of the oil reservoir 15. A three-way pipe 22 is fixedly connected to the output end of the metering pump 21. A second valve 24 is fixedly connected to the left side of the three-way pipe 22. A first valve 23 is fixedly connected to the front of the three-way pipe 22. A hose 25 is fixedly connected to the left side of the second valve 24. A handle pipe 26 is fixedly connected to the end of the hose 25 away from the second valve 24.

The differential is connected to a filling pipe 28. In the initial state, valve 23 is closed and valve 24 is open. The filling pipe 28 is inserted into the lubricating oil filling port of the differential. The user can set the filling amount through the PLC controller 11, and then control the metering pump 21 to work through the PLC controller 11. The metering pump 21 can draw a certain amount of lubricating oil from the oil reservoir 15 and deliver it to the inside of the differential through the three-way pipe 22, valve 24, hose 25, handle pipe 26, bend pipe 27 and filling pipe 28 to realize the function of metered filling and avoid the problem of lubricating oil waste or insufficient filling.

[0035] As an implementation form in the embodiment, as shown in Figure 3 The inner wall of the filling end pipe 28 is fixedly provided with a porous partition plate 281.

The lubricating oil inside the oil storage cylinder 15 is extracted and delivered to the inner cavity of the heating bin 32 through the return pipe 31. Then, the lubricating oil flows through the outer surface of the copper pipe 33 under the action of gravity and the blocking of the symmetric flow guide plate 35. At the same time, the electric heating rod 34 is controlled to work. The lubricating oil is heated by the copper pipe 33, so as to realize the internal circulation and temperature rising of the lubricating oil, improve the uniformity of the lubricating oil, and improve the uniformity of the lubricating oil.
