Description

Technical Field

[0001] This utility model relates to the field of electric spindle sealing technology, specifically to an integrated structure for spindle oil mist collection and sealing. Background Technology

[0002] Common lubrication methods for electric spindle bearings include grease lubrication, oil mist lubrication, and oil-air lubrication. Oil mist lubrication is suitable for high-speed, light-load spindle bearings and also has a cooling effect.

[0003] Even with oil mist lubrication, oil mist can still diffuse outwards through sealed end caps at both ends of the electric spindle. Current technology uses independent external oil mist purifiers, but their negative pressure adsorption efficiency is limited by the distance to the equipment and the airflow path. Some oil mist particles still escape through mechanical gaps. Uncaptured oil mist mixes with the machine tool coolant to form emulsions, leading to lubrication system failure, environmental pollution, and oil waste. Therefore, an integrated structure for spindle oil mist collection and sealing is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated structure for collecting and sealing oil mist from the spindle, thereby solving the problems mentioned in the background section. To solve these technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is an integrated structure for main shaft oil mist collection and sealing, comprising:

[0006] A sealing cover is fixed to one end of the electric spindle bushing near the output end of the spindle, and has a hole in the middle to facilitate the output end of the spindle to extend out.

[0007] An oil guiding assembly includes a first groove, a second groove, a cotton suction ring, and a first opening. The second groove is formed on the inner wall of the middle hole of the sealing cap, the first groove is formed on the bottom surface of the second groove, the cotton suction ring is engaged in the second groove, and the first opening is formed on the bottom surface of the first groove.

[0008] Furthermore, the oil guiding assembly also includes a conical groove and a T-shaped cotton strip, wherein the conical groove is formed at the upper end of the first opening, and the T-shaped cotton strip is inserted into the first opening and the conical groove.

[0009] Furthermore, the oil guiding assembly also includes a threaded tube, which is fixed at the opening of the first opening located at the lower end of the sealing cap, and is connected to an external oil recovery mechanism via an oil pipe.

[0010] Furthermore, the upper diameter of the T-shaped cotton strip is larger than the diameter of the first opening, but smaller than the outer diameter of the conical groove.

[0011] Furthermore, a fixing plate is welded to the top surface of the second groove near the center of the sealing cover. The upper end of the cotton-absorbing ring is attached to the side of the fixing plate, and the lower end is attached to the bottom surface of the second groove near the center of the sealing cover.

[0012] Furthermore, the outer ring of the sealing cover has a first mounting hole, and the central hole of the sealing cover is welded to a slot.

[0013] Furthermore, it also includes a limiting component, which includes a limiting ring and a second opening. The limiting ring is engaged in the second groove and fits against the outside of the cotton suction ring, and the second opening is formed on the limiting ring.

[0014] Furthermore, the limiting component also includes a tapered tube and a second mounting hole. The tapered tube is fixed to the outside of the limiting ring and located at the second opening. The second mounting hole is opened on the limiting ring and fixed to the fixing plate at the top of the second groove by screws.

[0015] This utility model has the following beneficial effects:

[0016] This invention utilizes an oil-guiding assembly to insert a cotton-absorbing ring into a second groove, into which a sealing ring is inserted. The sealing cover is then fixed to the electric spindle. During use, oil mist particles inside the electric spindle diffuse to the sealing cover and are absorbed by the cotton-absorbing ring. Once the cotton-absorbing ring is saturated with oil, it falls into the first groove, flows onto a T-shaped cotton strip in a conical groove, and then flows out through the T-shaped cotton strip in the first opening. Finally, it flows through an oil pipe to an external oil recovery mechanism. This design allows for direct recovery of oil mist inside the electric spindle, reducing the probability of oil mist particles overflowing and minimizing environmental pollution.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is an integrated structure for main shaft oil mist collection and sealing, comprising:

[0028] The sealing cover 10 is fixed to one end of the electric spindle bushing near the output end of the spindle, and has a hole in the middle to facilitate the output end of the spindle to extend out.

[0029] The outer ring of the sealing cover 10 has a first mounting hole 11, and the middle hole of the sealing cover 10 is welded to the slot 12.

[0030] The sealing cover 10 is used to seal both ends of the electric spindle. The first mounting hole 11 facilitates the screw fixing of the sealing cover 10. The slot 12 is used to install the sealing ring.

[0031] The oil guiding assembly includes a first groove 20, a second groove 21, a cotton suction ring 22, and a first opening 23. The second groove 21 is formed on the inner wall of the middle hole of the sealing cover 10. The first groove 20 is formed on the bottom surface of the second groove 21. The cotton suction ring 22 is engaged in the second groove 21. The first opening 23 is formed on the bottom surface of the first groove 20.

[0032] The oil guiding assembly also includes a tapered groove 24 and a T-shaped cotton strip 26. The tapered groove 24 is opened at the upper end of the first opening 23, and the T-shaped cotton strip 26 is inserted into the first opening 23 and the tapered groove 24.

[0033] The oil guiding assembly also includes a threaded tube 25, which is fixed at the opening of the first opening 23 located at the lower end of the sealing cover 10 and is connected to an external oil recovery mechanism through an oil pipe.

[0034] The upper diameter of the T-shaped cotton strip 26 is larger than the diameter of the first opening 23, but smaller than the outer diameter of the conical groove 24;

[0035] A fixing plate is welded to the top surface of the second groove 21 near the center of the sealing cover 10. The upper end of the cotton-absorbing ring 22 is attached to the side of the fixing plate, and the lower end is attached to the bottom surface of the second groove 21 near the center of the sealing cover 10.

[0036] The first groove 20 and the second groove 21 facilitate the collection of oil. The absorbent ring 22 is used to absorb the oil mist. The first opening 23 can output the oil in the first groove 20. The conical groove 24 serves as a guide. The threaded tube 25 is used to connect to the external oil pipe. The T-shaped cotton strip 26 can absorb the oil.

[0037] Working principle:

[0038] The suction ring 22 is inserted into the second groove 21, and the sealing ring is inserted into the groove 12. The sealing cover 10 is fixed to the electric spindle. During use, the oil mist particles inside the electric spindle diffuse to the sealing cover 10 and are absorbed by the suction ring 22. After the suction ring 22 is saturated with oil, it falls into the first groove 20 and flows into the T-shaped cotton strip 26 in the conical groove 24. It then flows out through the T-shaped cotton strip 26 in the first opening 23 and flows through the oil pipe to the external oil recovery mechanism.

[0039] This step allows for the direct recovery of oil mist inside the electric spindle, reducing the probability of oil mist particles overflowing and minimizing environmental pollution.

[0040] Please see Figure 5 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The limiting component includes a limiting ring 30 and a second opening 31. The limiting ring 30 is engaged in the second groove 21 and fits against the outside of the cotton suction ring 22. The second opening 31 is opened on the limiting ring 30.

[0042] The limiting assembly also includes a tapered tube 32 and a second mounting hole 33. The tapered tube 32 is fixed to the outside of the limiting ring 30 and is located at the second opening 31. The second mounting hole 33 is opened on the limiting ring 30 and is fixed to the fixing plate at the top of the second groove 21 by screws.

[0043] The limiting ring 30 allows for the backflow of oil in the spindle without electricity. The second opening 31 facilitates the flow of oil to the first groove 20. The tapered tube 32 serves as a guide, and the opening at the other end of the tapered tube 32 is inclined towards the bottom surface of the first groove 20 for guiding purposes. The smaller diameter also prevents oil from overflowing. The second mounting hole 33 is used to fix the limiting ring 30.

[0044] Working principle:

[0045] The absorbent ring 22 is fixed to the inside of the limiting ring 30 with screws, and the screws are inserted into the second mounting hole 33. Then the limiting ring 30 and the absorbent ring 22 are snapped into the second groove 21 and fixed to the fixing plate in the second groove 21. When in use, the oil absorbed by the absorbent ring 22 passes through the second opening 31 and then falls into the first groove 20 from the tapered tube 32.

[0046] This step, with its gradient anti-backflow design, prevents oil spillage.
