[0027] like Figures 1 to 7As shown, the damper metering refueling machine of the invention includes: a frame 1, a damper cylinder fixing plate 2, an oil tank 3, and a metering refueling mechanism 4. The frame 1 includes a workbench 5 and a support 6 mounted on the workbench 5. The damper cylinder fixing plate 2 is slidably mounted on the workbench 5, and a set of damper cylinder fixing holes 7 are provided on the surface of the damper cylinder fixing plate 2, into which the damper cylinder 51 is inserted. The oil tank 3 is mounted on the support 6, and an oil outlet pipe 8 is provided at the bottom of the oil tank 3. The metering refueling mechanism 4 is located above the damper cylinder fixing plate 2, and the metering refueling mechanism 4 includes a movable plate 9, a fixed plate 10, a piston 11, a first one-way valve 12, a template-type cylinder assembly 13, a second one-way valve 14, and a needle-type oil nozzle 15. The movable plate 9 is vertically movable above the workbench 5. The template-type cylinder assembly 13 is fixedly disposed below the movable plate 9. A set of pistons 11 are installed side-by-side below the movable plate 9. The template-type cylinder assembly 13 is mounted on the fixed plate 10. The template-type cylinder assembly 13 consists of an upper template cylinder 16 and a lower template cylinder 17, which are fixed together by pins. The upper template cylinder 16 has a set of cavities 18 that cooperate with the pistons 11. A set of first one-way valves 12 are installed side-by-side below the lower template cylinder 17, and a set of second one-way valves 14 are installed side-by-side on the side of the lower template cylinder 17, corresponding one-to-one with the first one-way valves 12. Ideally, the first one-way valves 12 and the second one-way valves 14 are set at a 90-degree angle to facilitate the machining of mounting holes. The lower template cylinder 17 is provided with a main oil passage 19 that communicates with each of the second one-way valves 14, and a branch oil passage 20 that communicates with the cavity 18 of the upper template cylinder 16 is provided between the adjacent first one-way valves 12 and second one-way valves 14 of the lower template cylinder 17. The lower end of the oil outlet pipe 8 is connected to the main oil passage 19, and the needle-type oil injection nozzle 15 is installed at the lower end of the first one-way valve 12. Working principle: Before adding oil, hydraulic oil is first injected into the oil storage tank 3. The hydraulic oil flows into the main oil passage 19 through the oil outlet pipe 8. The cylinder 30 pushes the movable plate 9 up, driving the piston 11 to pull up and draw the hydraulic oil in the main oil passage 19 into the cavity 18. Then, the damper cylinder 51 on the damper cylinder fixing plate 2 is pushed to the position directly below the needle-type oil injection nozzle 15. Finally, the cylinder 30 reverses its action to inject hydraulic oil into the damper cylinder 51. The advantages of the above structure are: 1. Quantitative hydraulic oil filling is achieved by quantitatively extracting hydraulic oil; 2. The amount of hydraulic oil extracted can be adjusted as needed (based on the pull-out height of piston 11) to meet the filling needs of different types of damper cylinders; 3. Multiple cylinders can be filled at once, and the quantity can be increased or decreased as needed.

The universal joint connector comprises a ball joint head 35 integrally formed on the lower end of the piston rod 32 and a joint socket 36 located on the upper end of the piston head 31 and connected to the ball joint head 35. The connection between the piston head 31 and the piston rod 32 via the universal joint connector can prevent breakage between the piston head 31 and the piston rod 32 or the generation of gaps between the piston head 31 and the cavity 18.

[0033] Preferably, the first check valve 12 includes a first valve body 37, a first valve core 38 disposed within the first valve body 37, a first valve body spring 39 disposed within the first valve core 38, and a first steel ball 40 disposed above the first valve body spring 39.

The above-described second check valve 14 has the advantages of simplicity, reliability, and convenient installation.

[0035] Preferably, the oil storage tank 3 has oil outlet pipes 8 on both sides of its bottom, and each oil outlet pipe 8 is equipped with a valve 47. The two oil outlet pipes 8 are used to increase the oil output speed, and the valves 47 control the oil output of the oil outlet pipes 8. When not in operation, the oil circuit is closed.

[0036] Preferably, a sealing ring 48 is provided at the connection between the cavity 18 of the upper template cylinder 16 and the branch oil passage 20 to improve sealing performance. A cap 49 is provided at the upper end of the cavity 18, and a positioning plate 50 is provided at the upper end of the upper template cylinder 16.
