Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil mist device technology, specifically to an oil mist device and a CNC machining center. Background Technology
[0002] In existing CNC machining centers, the air hoses for the oil mist device are secured to the nozzles and oil hoses with multiple cable ties, which has the following disadvantages:
[0003] 1. The angle needs to be adjusted at the front end of the trachea, which takes a long time and results in low work efficiency.
[0004] 2. Using cable ties to secure the trachea is unsightly, cumbersome, and can cause deformation, resulting in low reusability of the trachea.
[0005] 3. High air pressure may blow away the cable ties at the front, resulting in insufficient stability of the air hose installation.
[0006] 4. The oil pipe is tightened by the cable tie, causing it to compress and deform. This makes the nozzle prone to spot spraying, affecting the processing effect.
[0007] 5. High manufacturing costs. Utility Model Content

[0029] See Figure 1-4 As shown in the figure, as an embodiment of the present invention, an oil mist device is provided, including a nozzle 1, an air pipe 2, and an oil pipe 3. One end of the oil pipe 3 is fixedly installed at the rear end of the nozzle 1, and a through hole is opened at the front end of the nozzle 1. The front end of the air pipe 2 is inserted into the nozzle 1 through the through hole. The nozzle 1 includes a conical body 11 and a cylindrical body 12 coaxially connected at both ends. The diameter of the conical body 11 gradually decreases in the direction away from the cylindrical body 12. The oil mist device of the present invention has the following advantages compared with the oil mist devices of the prior art:
[0030] 1. No cable ties are needed to secure the trachea 2. The trachea 2 can be plugged in and used immediately. The operation is simple and quick. There is no need to frequently adjust the angle of the trachea 2, which improves work efficiency.
[0031] 2. More aesthetically pleasing, the trachea 2 will not deform, improving the reusability of the trachea 2.
[0032] 3. The installation stability of air tube 2 is good.
[0033] 4. The oil pipe 3 will not be tightened by the cable tie, so the oil pipe 3 will not be compressed and deformed. Therefore, the nozzle 1 will not have spot spraying, resulting in better processing effect.
[0034] 5. Low manufacturing cost.
[0035] Specifically, the through hole is located at the cone body 11, and the through hole is an inclined through hole that gradually approaches the central axis of the nozzle 1 from back to front, so that the front end of the air tube 2 can be inserted into the nozzle 1 more stably through the inclined through hole, further improving the insertion stability.
[0036] In this embodiment, a clamp 4 is also included. A bayonet structure is provided at the end of the cylindrical body 12 away from the conical body 11. The bayonet structure includes a concave ring 5 and a plurality of claw portions 6 located at the rear end of the concave ring 5 and spaced apart along the circumferential direction. The clamp 4 is fitted onto the outside of the claw portions 6, so that the plurality of claw portions 6 contract radially inward to fix one end of the oil pipe 3 to the rear end of the nozzle 1. The clamp 4 is locked in the position of the claw portions 6, avoiding the compression deformation of the oil pipe 3 caused by the binding effect of the strap. Therefore, the nozzle 1 will not have spot spraying phenomenon, improving the processing effect. At the same time, it further improves the locking stability, so that the accessories will not be blown away or fall off due to high air pressure. Meanwhile, the locking area is only at the claw portion 6 of the nozzle 1, and will not affect the bending and angle adjustment of the air pipe 2.
[0037] In this embodiment, a limiting step 7 is formed between the concave ring portion 5 and the cylindrical body 12. An inclined surface 8 and a limiting surface 9 are formed on the outer side of the claw portion 6. The limiting surface 9 is located at the end of the inclined surface 8 away from the concave ring portion 5. The inclined surface 8 gradually tilts outward along the direction close to the limiting surface 9. The clamp 4 is tightly fitted on the inclined surface 8 to ensure the locking stability of the clamp 4 and prevent slippage or loosening.
[0038] This utility model also provides a CNC machining center, including the oil mist device described in the above embodiments, which has the following advantages:
[0039] 1. No cable ties are needed to secure the trachea 2. The trachea 2 can be plugged in and used immediately. The operation is simple and quick. There is no need to frequently adjust the angle of the trachea 2, which improves work efficiency.
[0040] 2. More aesthetically pleasing, the trachea 2 will not deform, improving the reusability of the trachea 2.
[0041] 3. The installation stability of air tube 2 is good.
[0042] 4. The oil pipe 3 will not be tightened by the cable tie, so the oil pipe 3 will not be compressed and deformed. Therefore, the nozzle 1 will not have spot spraying, resulting in better processing effect.
[0043] 5. Low manufacturing cost.
