[0002] Currently, the oiling operation of gears is basically manual, with low work efficiency and poor oiling uniformity of gears, affecting product quality. The "small gear device with thin oil lubrication" disclosed in the patent application number "CN201721720829.4" is also an increasingly mature technology. By changing the original grease-lubricated small gear device to thin oil lubrication, the effects of reducing the friction coefficient, reducing wear, lowering temperature, alleviating shock, reducing vibration, and saving space can be achieved. However, this device still has the following defects: during actual use, it cannot lubricate gears in large quantities. At the same time, it is difficult for lubricating oil to enter the tooth slot gaps of gears during lubrication, resulting in limited lubrication effect. During the lubrication process, it is difficult to recycle the excess lubricating oil, causing waste of lubricating oil. Content of the Utility Model

[0003] The purpose of the utility model is to provide an oiling device for the edge gap of a small gear, aiming to solve the problems in the prior art that gears cannot be lubricated in large quantities, it is difficult for lubricating oil to enter the tooth slot gaps of gears during lubrication, the lubrication effect is limited, and it is difficult to recycle the excess lubricating oil during the lubrication process, resulting in waste of lubricating oil.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an oiling device for the edge gap of a small gear, including a support base. A conveyor belt is arranged on the top of the support base, and a number of gear storage rotating shafts are distributed on the top of the conveyor belt. One side of the top of the support base is provided with a support frame, and an oil storage tank for thin oil is arranged on one side of the support frame. A micro oil pump is arranged on the top of the oil storage tank for thin oil, a flow-limiting solenoid valve is arranged at the oil outlet end of the micro oil pump, a shunt pipe is connected to the oil outlet end of the flow-limiting solenoid valve through a pipe, a drip plate is arranged on the top of the support frame, the shunt pipe is embedded in the top of the drip plate, and funnel-shaped drip holes are distributed at the bottom of the drip plate. The funnel-shaped drip holes are hermetically communicated with the shunt pipe.

[0005] In an embodiment of the oiling device for the edge gap of a small gear of the utility model, a limiting groove is opened at the top of the other side of the support frame, and a rack is snap-fitted in the limiting groove.

[0006] In this solution, the micro oil pump pumps the thin oil into the shunt pipe and flows out from the funnel-shaped drip holes. The thin oil seeps into the tooth slots on the surface of the rack and the meshing connection with the small gear for lubrication. As the conveyor belt moves, the small gear meshes with the lubricated rack during the movement process, and the lubricating oil is evenly smeared at the gap of the small gear. During the movement process of the small gear, the drip plate presses against the top of the small gear to prevent the small gear from falling off during the movement process.

[0007] In the implementation scheme of the oiling device for the edge gap of the small gear of the present utility model, first threaded holes are provided on both sides of the top of the support frame, second threaded holes are provided on both sides of the rack, and third threaded holes are provided on both sides of the bottom of the inner wall of the limiting groove. Screws are threadedly connected between the first threaded holes, the second threaded holes, and the third threaded holes.

[0011] In the implementation scheme of the oiling device for the edge gap of the small gear of the present utility model, an oil return pump is provided on one side of the thin oil storage tank. The oil inlet end of the oil return pump is connected to an oil return pipe, and one end of the oil return pipe penetrates through one side of the support frame and is hermetically connected to the bottom of the collection box.

[0013] In the implementation scheme of the oiling device for the edge gap of the small gear of the present utility model, a drainage plate is fixedly installed on one side of the support frame.

[0014] In this scheme, during the lubrication process of the thin lubricating oil, the dripping lubricating oil is buffered by the drainage plate to prevent the lubricating oil from splashing after dropping. The lubricating oil buffered by the drainage plate falls into the collection box for recycling.

[0020] 1) By providing means for respectively storing and collecting the gears to be processed and the processed gears, automatic feeding and discharging are completed through the electric telescopic rod, the micro motor, and the electric fixture, saving labor and improving production efficiency at the same time. During the lubrication process, the use of lubricating oil is saved through the funnel-shaped drip holes, and at the same time, the lubricating oil evenly enters the tooth grooves of the pinion gear.

On the top of the electric telescopic rods 21, a micro motor 22 is provided. On the top of the micro motor 22, a loading and unloading electric clamp 23 is provided.

[0040] Please refer to Figure 1 : During use, the electric telescopic rod 21 on one side adjusts the clamping height of the loading and unloading electric fixture 23 through telescoping, sleeves the gear on the gear storage rotating shaft 3 to complete loading. After the small gear is lubricated, the electric telescopic rod 21 on the other side moves the loading and unloading electric fixture 23, and the loading and unloading electric fixture 23 clamps the lubricated small gear to complete unloading.

[0041] In a specific embodiment of the oiling device for the edge gap of the small gear, please refer to Figure 1 : There are storage seats 24 on both sides of the support seat 1, and gear placement columns 25 are provided on the top of the storage seats 24.

[0042] Please refer to Figure 1 : During loading, the electric telescopic rod 21 lifts, and the micro motor 22 on one side rotates the loading and unloading electric fixture 23. After moving the position of the loading and unloading electric fixture 23, the electric telescopic rod 21 descends to the specified height for clamping the gear. The loading and unloading electric fixture 23 clamps the gear stacked on the top layer, removes the gear from the gear placement column 25 on one side of the storage seat 24. The electric telescopic rod 21 lifts, and the gear disengages from the gear placement column 25. Then the micro motor 22 rotates the loading and unloading electric fixture 23, and the electric telescopic rod 21 descends to place the clamped gear at the gear storage shaft 3. After the loading and unloading electric fixture 23 releases the gear, it resets. When the gear moves to the other side after lubrication, the loading and unloading electric fixture 23 uses the reverse operation to clamp and disengage the lubricated gear from the gear placement column 25, and sleevingly stacks the lubricated gears on the gear placement column 25 on the other side in sequence to complete automatic loading and unloading and reduce manual operation.

[0043] A lubricating device for the edge gap of a small gear provided by the present utility model has the following specific usage method: Stack the gears to be processed on the gear placement column 25 on one side. Lift the electric telescopic rod 21, and rotate the loading and unloading electric fixture 23 by the micro motor 22 on one side. After moving the position of the loading and unloading electric fixture 23, lower the electric telescopic rod 21 to the specified height for clamping the gear. The loading and unloading electric fixture 23 clamps the uppermost stacked gear, removes the gear from the gear placement column 25 on the storage seat 24 on one side. Lift the electric telescopic rod 21, and the gear disengages from the gear placement column 25. Then, rotate the loading and unloading electric fixture 23 by the micro motor 22, lower the electric telescopic rod 21, and place the clamped gear on the gear storage shaft 3. After the loading and unloading electric fixture 23 releases the gear, it resets. As the conveyor belt 2 rotates, it drives the gear storage shaft 3 to move to the rack 12. At this time, the micro oil pump 6 pumps the washing oil into the shunt pipe 8 and flows out from the funnel-shaped drip holes 10. The thin oil seeps into the tooth grooves on the surface of the rack 12 and the meshing connection with the small gear for lubrication. As the conveyor belt 2 moves, the small gear meshes with the lubricated rack 12 during the movement, and evenly applies the lubricating oil to the gap of the small gear. During the movement of the small gear, the drip plate 9 abuts against the top of the small gear to prevent the small gear from falling off during the movement. When the gear is lubricated and moves to the other side, the loading and unloading electric fixture 23 uses the opposite operation to clamp and disengage the lubricated gear from the gear placement column 25, and sequentially stack the lubricated gears on the gear placement column 25 on the other side, completing automatic loading and unloading, reducing manual operation. The lubricating oil dripping during the lubrication process of the thin lubricating oil is buffered by the drainage plate 20 to prevent the lubricating oil from splashing after dropping. The lubricating oil buffered by the drainage plate 20 falls into the collection box 16 for recycling. The recycled lubricating oil in the collection box 16 is pumped back into the thin oil storage tank 5 through the oil return pump 18 and the oil return pipe 19 to avoid waste of lubricating oil.
