Description

Technical Field

[0001] This application relates to the fields of machining and automated production lines, and particularly to a rotary air blowing device. Background Art

[0002] During the numerical control machining process, the waste chips generated on the workpiece need to be blown clean before the next process. Generally, an air blowing device is used to blow away the waste chips. Especially in the automated production line of deep-hole machining parts, a large amount of material waste residue will accumulate in the holes during the machining process of such parts, and waste chips often remain in the machining holes. If these waste chips are not cleaned in time, it will affect the machining quality and the normal operation of the equipment.

[0003] On the one hand, the traditional air blowing method cannot clean comprehensively, it is difficult to blow the material waste residue clean, and waste chips will still remain in the dead corners. When the robot unloads the material, the product will carry the waste residue to the bin together, which not only affects the 7S standard of the site but also affects the feeding of the next process. On the other hand, if manual cleaning is required again, fully automated production cannot be achieved. Utility Model Content

[0027] In the automated production line for turning deep-hole parts, a large amount of material waste residue will accumulate in the hole during the processing. The traditional air blowing method cannot clean it comprehensively in all directions, and it is very difficult to blow the material waste residue clean. If manual cleaning is required again, full-automatic production cannot be achieved. If manual cleaning is not required again, when the robot unloads the material, the product will carry the waste residue into the bin, which will not only affect the 7S standard of the site, but also affect the feeding of the next process.

[0028] The present application provides a rotary air blowing device for the automated production line of turning deep-hole parts, which can realize 360° full-automatic air blowing in the hole, improve the chip blowing efficiency and cleaning effect of the deep hole, and improve the automation.

[0029] In an embodiment of the present application, a rotary air blowing device is provided, which includes an air inlet part 1, a mounting part 2 and a rotating part 4 connected in sequence; the mounting part 2 is used to be mounted on the processing equipment, generally a numerical control processing equipment. The air inlet part 1 and the rotating part 4 are connected and penetrated through a bearing fixing part 3, and the bearing fixing part 3 is arranged and mounted on the mounting part 2; the rotating part 4 includes a hollow rod 41 and a rotating bearing 42. The hollow rod 41 is rotatably connected to the mounting part 2 through the rotating bearing 42. One end of the hollow rod 41 is internally connected to the air inlet part 1 to form an air flow channel. A plurality of air outlet ports 43 for blowing air are arranged on the hollow rod 41 and are communicated with the inner cavity of the hollow rod 41. The hollow rod 41 is used to extend into the processing hole to remove the waste chips in the hole, and the plurality of air outlet ports 43 are arranged staggered along the length direction of the hollow rod 41.

[0030] Please refer to Figure 1 , the air outlet port 43 includes a first air outlet port 431 and a second air outlet port 432. The first air outlet port 431 is arranged at the front end of the hollow rod 41 for removing the waste chips at the front end of the processing hole. The second air outlet port 432 is arranged on the circumferential side wall of the hollow rod 41 for removing the waste chips on the circumferential side wall of the processing hole. The second air outlet ports 432 are evenly distributed on the circumferential side wall of the hollow rod 41 so that the two sides of the rotating part 4 are subjected to equal forces. The second air outlet ports 432 are arranged staggered along the length direction of the hollow rod 41 so that the air flow discharged from the second air outlet ports 432 forms a reaction thrust to drive the hollow rod 41 to rotate.

[0031] Specifically, in the embodiment of the present application, there are two groups of second air outlets 432 symmetrically distributed along the circumference of the hollow rod 41. Each group of second air outlets 432 is distributed along the length direction of the hollow rod 41. The two groups of second air outlets 432 are staggered along the length direction of the hollow rod 41, so that the air outlet directions are staggered. When blowing chips from parts with deep holes, the external air source is connected to the air inlet 1. After the air source enters the hollow rod 41 of the rotating part 4 from the air inlet 1, high pressure is formed inside. The high-pressure air is discharged through the air outlet 43. The hollow rod 41 can be extended into the hole. The high-pressure air is ejected from the second air outlet 432 to generate a reverse thrust. The reaction thrust can serve as an energy source to rotate the hollow rod 41 relative to the mounting part 2 to achieve 360° all-round blowing. After the inner hole is processed, it is extended into the hole for blowing and slag removal. Continuous air jetting can prevent waste chips from entering the hole and causing blockage, thereby improving chip blowing efficiency and improving automation.

[0033] Please refer to Figure 1 The outer rings of the connecting section 31 and the limiting section 32 are arranged in a stepped shaft, and the connecting section 31 is clearance-matched with the through hole 21 so that the connecting section 31 can freely enter and exit the through hole 21. The diameter of the limiting section 32 is larger than the diameter of the through hole 21, so that after the connecting section 31 extends into the through hole 21, the limiting section 32 is stuck on the outside of the through hole 21.

[0034] Please refer to Figure 1 In this embodiment, the air intake part 1 is configured as an air pipe joint and is threadedly installed on the connecting section 31, so that the air intake part 1, the bearing fixing part 3 and the rotating part 4 are sequentially connected to form an air flow channel; specifically, the air intake part 1 includes a threaded section 11, a locking section 12 and an interface section 13 arranged in sequence, the threaded section 11 extends into the through hole 21 and is threadedly connected to the connecting section 31. In this embodiment, the threaded section 11 is configured as an external thread and the connecting section 31 is configured as an internal thread to achieve a threaded connection between the two; the diameter of the locking section 12 is larger than the diameter of the through hole 21, so that when the threaded section 11 is connected to the connecting section 31, the locking section 12 is locked on the outside of the through hole 21; the interface section 13 is one end of the air inlet, which is used to connect the air pipe to enter the external air source.

[0035] In the embodiment of the present application, the bearing fixing part 3 is integrally fixed on the mounting part 2 to provide support for the whole blowing device, ensuring the stability during the chip blowing process.

The second air outlets 432 are staggered and evenly distributed on the circumferential side wall of the hollow rod 41, so that when the air flows out from the second air outlets 432, a reaction thrust is formed to drive the hollow rod 41 to rotate automatically, and at the same time, ensure that the forces on both sides of the rotating part 4 are equal. The air inlet part 1, the bearing fixing part 3 and the rotating part 4 are sequentially penetrated to form an air flow channel. Compressed air enters from the interface section 13 of the air inlet part 1, passes through the threaded section 11 and the connecting section 31, enters the hollow rod 41, and then blows out from the first air outlet 431 and the second air outlets 432 to remove the chips in the processing hole, without manual cleaning, and the chip blowing efficiency is high, and the effect is stable and effective.

[0038] During the actual use process, in order to ensure the stability and cleaning effect of the device, the data of the inlet air pressure and the parameters such as the length, diameter of the hollow rod 41, and the size and quantity of the air outlets 43 can be adjusted according to the sizes of different parts and the processing requirements to achieve the best cleaning effect. At the same time, in order to ensure the stability and reliability of the device, the rotating bearing 42 can be lubricated and maintained regularly to ensure that the hollow rod 41 can rotate smoothly.
