[0001] The utility model relates to the technical field of lubricating oil filling, in particular to a machine oil filling tool. Background Art

[0002] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering.

[0003] When lubricating various mechanical parts, bearings and other joint components, most of them are still done by manual oil filling. When manually filling the oil, the operator holds the refueling pipeline to fill grease or oil to the position of the mechanical parts. The amount of oil filled depends entirely on the proficiency and experience of the operator. When the amount of oil added is insufficient, it cannot protect the mechanical parts. When the oil is filled too much, the oil will overflow and pollute the adjacent mechanical parts, and it will also cause a waste of oil. It is impossible to achieve quantitative filling of oil and the filling speed of oil cannot be controlled. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide an oil filling tool, which can realize automatic quantitative filling of oil to mechanical parts, avoids the use of multiple sensors, has low cost, stable structure, simple operation and high practicality.

[0015] 1. The oil filling tool of the utility model example can gradually push the push-pull rod toward the oil storage cylinder through the cooperation of the through groove, the lever and the stopper, so that the piston moves the same range each time inside the oil storage cylinder.

[0034] Example: Reference Figure 1-7 An oil filling tool shown in the figure comprises a base plate 1, a block 11, an adjusting cylinder 14 and an oil storage cylinder 2 are fixed on the upper surface of the base plate 1, the adjusting cylinder 14 is located between the block 11 and the oil storage cylinder 2, one end of the oil storage cylinder 2 is fixedly connected with an oil suction pipe 3 and an oil outlet pipe 4, a piston 5 is slidably fitted in the oil storage cylinder 2, a push-pull rod 6 is fixed on one side of the piston 5, one end of the push-pull rod 6 slides through the oil storage cylinder 2, a plurality of through grooves 7 are provided on the upper surface of the push-pull rod 6 along a linear array, a freely liftable lifting plate 18 is provided on the top of the base plate 1, a lever 10 is rotatably connected to one side of the lifting plate 18, and a positioning plate 24 is slidably fitted on the top of the adjusting cylinder 14 for preventing the push-pull rod 6 from being pulled back.

[0035] The bottom end of the lever 10 is in sliding contact with the sliding surface 12, and the bottom end of the lever 10 gradually swings toward the lower right and squeezes the groove 7 until the lever 10 is completely in a vertical state. The push-pull rod 6 is pushed forward to a preset range, and the piston 5 moves the same range inside the oil storage cylinder 2 each time. The oil in the oil storage cylinder 2 will be squeezed out through the oil outlet pipe 4. At this time, the positioning plate 24 at the top of the regulating cylinder 14 will slide into the groove 7 at its top to lock the groove 7. When the lever 10 rises vertically, it will be subjected to a leftward rotational force, causing it to swing to the left until it returns to its initial position. The positioning plate 24 can prevent the push-pull rod 6 from being pulled back due to the swing force of the lever 10.

[0036] In order to realize the automatic lifting and lowering of the lever 10 and continuously give a torsion force to swing back on one side of the lever 10, in this embodiment, a sliding surface 12 is provided on one side of the block 11, a top plate 9 is fixed on the top of the bottom plate 1, an electric push rod 17 is installed on the top plate 9, a lifting plate 18 is fixedly connected to the output end of the electric push rod 17, a side plate 19 is fixed on one side of the lifting plate 18, a rotating plate 20 is rotatably connected to one side of the side plate 19, the top of the lever 10 is fixedly connected to the rotating plate 20, and a torsion spring 21 is fixed between the rotating plate 20 and the side plate 19. The electric push rod 17 can drive the lever 10 to lift vertically, and the setting of the torsion spring 21 can give the lever 10 a continuous swing back force, prompting it to return to its initial state.

[0037] In order to improve the stability of the lever 10 and the mechanical efficiency of the swing, in this embodiment, the bottom end of the lever 10 is rotatably connected with a roller 23, a buffer column 22 is fixed to one side of the bottom of the lifting plate 18, and an elastic rubber pad is fixed to one end of the buffer column 22. The setting of the elastic rubber pad on the buffer column 22 plays a role in buffering the impact force from the lever 10, the buffer column 22 can position the swing angle of the lever 10, and the setting of the roller 23 reduces the friction of the sliding contact between the bottom end of the lever 10 and the sliding surface 12, thereby improving the mechanical efficiency of the swing of the bottom end of the lever 10.

[0038] In order to make the positioning plate 24 better prevent the push-pull rod 6 from being pulled back, in this embodiment, the top and bottom sides of the through slot 7 are both provided with chamfers 8, and the top and sides of the positioning plate 24 are both provided with the same chamfers 8. The adjusting cylinder 14 is a hollow plate with an opening at the top, and both sides of the adjusting cylinder 14 are provided with clearance grooves 26. A second spring 27 is fixed between the lower surface of the positioning plate 24 and the inner bottom surface of the adjusting cylinder 14, and an adjusting plate 25 is fixed on both sides of the positioning plate 24, and the adjusting plate 25 is slidably fitted in the clearance grooves 26. When the lever 10 pushes the push-pull rod 6 to move, the chamfer 8 at the bottom of the through slot 7 will squeeze the chamfer 8 on the positioning plate 24, so that the positioning plate 24 retracts into the adjusting cylinder 14, and the second spring 27 is compressed. When the next through slot 7 moves to the top of the positioning plate 24, the positioning plate 24 will automatically slide into the through slot 7, and at this time, the swing force generated during the movement of the lever 10 can be prevented from driving the push-pull rod 6 to be pulled back, thereby locking the push-pull rod 6 and preventing the push-pull rod 6 from being pulled back.

[0039] Furthermore, in this embodiment, a baffle 15 is slidably sleeved on one end of the side surface of the push-pull rod 6 near the piston 5, a first spring 16 is fixed between the baffle 15 and the piston 5, a first oil valve 28 and a second oil valve 29 are installed on one end of the oil storage cylinder 2, one end of the oil extraction pipe 3 is connected to the first oil valve 28, one end of the oil outlet pipe 4 is connected to the second oil valve 29, and one end of the oil extraction pipe 3 and the oil outlet pipe 4 are both provided with an end cap 13. The setting of the baffle 15 and the first spring 16 plays a role in buffering the moving speed of the piston 5, making it more stable when absorbing the engine oil, the setting of the first oil valve 28 can make the engine oil only enter the oil storage cylinder 2 from the oil extraction pipe 3, and the setting of the second oil valve 29 makes the engine oil enter the oil outlet pipe 4 from the inside of the oil storage cylinder 2, the first oil valve 28 and the second oil valve 29 play the role of one-way valves, and the end cap 13 plays a role in preventing the residual engine oil in the oil outlet pipe 4 and the oil extraction pipe 3 from leaking.

[0040] Specific implementation and working principle:

[0041] When in use, the end cover 13 on the oil outlet pipe 4 can be removed first, the free end of the oil outlet pipe 4 can be aligned with the mechanical parts, and the electric push rod 17 can be started. After the electric push rod 17 is extended to the maximum distance, it will retract to the initial position to complete a range of movement. At this time, the engine oil is quantitatively discharged through the oil outlet pipe 4. When the engine oil inside the oil storage cylinder 2 is used up, the end cover 13 on the oil extraction pipe 3 is opened, and the free end of the oil extraction pipe 3 is placed in the oil barrel. Then, the adjustment plate 25 is pressed downward to make the positioning plate 24 slide out of the through groove 7, and the second spring 27 is compressed. At this time, one end of the push-pull rod 6 is pulled outward, and the engine oil can be drawn into the oil storage cylinder 2 through the oil extraction pipe 3. After completion, the pressing force of the adjustment plate 25 can be removed.
