[0028] Reference Figure 1-Figure 4 , is an embodiment of the utility model, which provides a micro-lubrication device with active oil supply, comprising:

[0029] The main unit 100 includes an oil cup 101 and a cover plate 102. A plurality of liquid level observation windows 108 are provided on the side wall of the oil cup 101. An oil mist chamber 107 is fixedly installed on the upper end of the oil cup 101.

[0030] The automatic oil filling assembly 200 includes an oil pump 201 and a bottom plate 203. The bottom plate 203 is fixedly connected to the inner wall of the oil cup 101. A waterproof trigger 204 is fixedly installed on the upper end of the bottom plate 203. Two support rods 205 are symmetrically fixedly connected to the upper end of the bottom plate 203. A fixed plate 206 is fixedly sleeved between the two support rods 205. A plurality of slide rods 207 are symmetrically slidably inserted into the inner wall of the fixed plate 206. The lower ends of the plurality of slide rods 207 are fixedly sleeved between the two support rods 205. A slide plate 208 is commonly fixedly connected, and the upper end of the slide plate 208 is symmetrically rotatably connected to two connecting rods 210, and the other end of each connecting rod 210 is rotatably connected to a slider 211, and two sliding grooves are provided at the lower end of the fixed plate 206, and a cross bar 214 is fixedly connected in each sliding groove, and each slider 211 is slidably sleeved on the cross bar 214, and a return spring 213 is sleeved on each cross bar 214, and a floating plate 209 is commonly fixedly installed on the upper ends of multiple sliding rods 207.

[0031] Under the action of buoyancy, the floating plate 209 drives the slide plate 208 to move upward through the slide rod 207 and stretches the reset spring 213. When the lubricating oil in the oil cup 101 is gradually consumed, the slider 211 is driven to move relatively under the elastic force of the reset spring 213. The slider 211 drives the slide plate 208 to move downward through the connecting rod 210. When the lubricating oil in the oil cup 101 reaches the warning line, the slide plate 208 is against the waterproof trigger 204. The waterproof trigger 204 sends a signal to the oil pump 201 to start it. The lubricating oil can be automatically added to the oil cup 101 through the oil pump 201. Therefore, the lubricating oil can be discovered and automatically replenished in time, thereby improving the lubrication effect and avoiding potential threats to the processing quality and efficiency.

[0032] The left side of the cover plate 102 is fixedly connected with an air inlet pipe 103 , and the right side of the cover plate 102 is fixedly connected with an air outlet pipe 104 . The air inlet pipe 103 and the air outlet pipe 104 are connected, and high-speed compressed gas is introduced through the air inlet pipe 103 .

[0033] The air inlet pipe 103 is connected to the inner cavity of the oil cup 101 through the connecting pipe 105 , and the air outlet pipe 104 is connected to the lubricating oil inside the oil cup 101 through the oil supply pipe 106 , and the lubricating oil can be added through the oil supply pipe 106 .

[0034] Among them, two fixed grooves are symmetrically opened in the two slide grooves, and two limit rods 212 are symmetrically fixedly connected on both sides of the two sliders 211. The opposite end of each limit rod 212 is slidably connected in the fixed groove, and the limit rod 212 can limit the slider 211.

[0035] Among them, the lower end of the oil pump 201 is fixedly connected to a support plate 202, one end of the support plate 202 is fixedly connected to the oil cup 101, the output end of the oil pump 201 is connected to the inside of the oil cup 101, and the input end of the oil pump 201 is fixedly installed with an oil filling pipe, which supports the oil pump 201 through the support plate 202.

[0036] Among them, the two ends of the two return springs 213 are respectively fixedly connected to the side wall of the slider 211 and the inner wall of the slide groove, and the waterproof trigger 204 is connected to the oil pump 201 through an electrical signal. The waterproof trigger 204 sends a signal to the oil pump 201 to start it.

[0037] Working principle: When in use, high-speed compressed gas is introduced through the air inlet pipe 103 and discharged through the air outlet pipe 104, wherein a small amount of lubricating oil enters through the oil supply pipe 106, and the lubricating oil is torn into fine particles by the compressed gas and discharged from the air outlet pipe 104 together with the compressed gas; when the amount of lubricating oil in the oil cup 101 is sufficient, the floating plate 209 drives the sliding plate 208 to move upward through the sliding rod 207 under the action of buoyancy and stretches the reset spring 213. When the lubricating oil in the oil cup 101 is gradually consumed, the sliding block 21 is driven by the elastic force of the reset spring 213. 1 moves relatively, the slider 211 drives the slide plate 208 to move downward through the connecting rod 210. When the lubricating oil in the oil cup 101 reaches the warning line, the slide plate 208 abuts against the waterproof trigger 204, and the waterproof trigger 204 sends a signal to the oil pump 201 to start it. The lubricating oil can be automatically added through the oil pump 201, so the lubricating oil can be found and automatically replenished in time, which improves the lubrication effect and avoids potential threats to the processing quality and efficiency. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
