Description

Technical Field

[0001] This utility model relates to the field of internal thread processing technology for ferrule-type connectors, and more specifically to a leak-proof ferrule-type connector internal thread processing device. Background Technology

[0002] Leak-proof ferrule fittings are components specifically designed to ensure leak-free connections in fluid systems. They employ a unique ferrule structure, achieving a highly efficient and reliable seal through a tight fit and mechanical locking principle. The working principle of leak-proof ferrule fittings is based on the elastic deformation and mechanical locking of the ferrule. When the nut is tightened, the ferrule is under pressure and undergoes elastic deformation, tightly wrapping around the surface of the pipe or fitting. This deformation not only fills any tiny gaps but also enhances the stability of the connection through mechanical locking. Even if the internal pressure of the system increases, the ferrule maintains its sealing performance, preventing fluid leakage.

[0003] Compression fittings have internal threads. The traditional processing flow involves manual feeding, clamping with a fixture, tapping the internal threads with a tapping machine, and unloading. This method of fixing compression fittings is complex and cannot achieve continuous operation. Therefore, a new technical solution is needed to address this issue. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a leak-proof ferrule type connector internal thread processing device, comprising: a base 1, wherein the base 1 has a rotating groove 24 inside, and a rotating shaft 23 is disposed inside the rotating groove 24; a large gear disk 2 is disposed on the upper part of the rotating shaft 23, and the large gear disk 2 is rotatably connected to the rotating groove 24; a drive motor 21 is disposed inside the base 1, and a drive gear 3 is disposed at the power output end of the drive motor 21; the drive gear 3 meshes with the teeth of the large gear disk 2; and a plurality of sets of insertion holes 18 are disposed inside the large gear disk 2. The base 1 is provided with a keyway 19. A plug-in post 14 is provided inside the plug-in hole 18, and a spline 15 matching the keyway 19 is provided outside the plug-in post 14. A mounting plate 13 is provided on the upper part of the plug-in post 14, and a fixing seat 16 is provided on the surface of the mounting plate 13. A fitting ferrule connector 12 is provided inside the fixing seat 16. A lifting seat 4 is provided on the side of the base 1, and a lifting rod 5 is provided inside the lifting post. A mounting seat 6 is provided on the upper part of the lifting rod 5, and a driver 8 is provided on the upper part of the mounting seat 6. A tool holder 11 is provided at the power output end of the driver 8. The tool holder 11 is internally equipped with a tapping head 9, including: a base 1, the base 1 having a rotating groove 24 internally, and a rotating shaft 23 internally; a large gear disc 2 being mounted on the upper part of the rotating shaft 23, and the large gear disc 2 being rotatably connected to the rotating groove 24; a drive motor 21 being internally equipped with a drive gear 3 at the power output end of the drive motor 21, the drive gear 3 meshing with the teeth of the large gear disc 2; and several sets of insertion holes 18 internally, with keyways 19 inside the insertion holes 18. The base 1 has an internal insertion post 14 and an external spline 15 that matches the keyway 19. The upper part of the insertion post 14 is provided with a mounting plate 13 and the surface of the mounting plate 13 is provided with a fixing seat 16. The fixing seat 16 has a fitting ferrule connector 12 inside. The side of the base 1 is provided with a lifting seat 4 and the inside of the lifting post is provided with a lifting rod 5. The upper part of the lifting rod 5 is provided with a mounting seat 6 and the upper part of the mounting seat 6 is provided with a driver 8. The power output end of the driver 8 is provided with a tool holder 11 and the inside of the tool holder 11 is provided with a tapping head 9.

[0019] Further improvements, such as Figure 2 , 3 As shown: The mounting plate 13 has a slot on its inner side and a locking element 17 inside the slot. The large gear 2 has a fixing hole 20 inside and the locking element 17 is connected to the fixing hole 20 by a bolt. This arrangement enhances the connection stability between the mounting plate 13 and the large gear 2, ensuring that the ferrule connector 12 will not loosen due to vibration or external force during processing, thus improving the processing accuracy and safety.

[0020] Further improvements, such as Figure 1 As shown: The upper part of the mounting base 6 is provided with a cooling box 7 and the lower part of the cooling box 7 is provided with a cooling nozzle 10. The cooling nozzle 10 extends to the tapping head 9. The introduction of the cooling system effectively reduces the heat generated by the tapping head 9 during the processing, and reduces the wear of the tool and the thermal deformation of the workpiece.

[0021] Further improvements, such as Figure 4 As shown: A bearing 22 is provided at the connection between the rotating shaft 23 and the base 1. The introduction of the bearing 22 reduces the frictional resistance between the rotating shaft 23 and the base 1, making the rotation of the large gear disk 2 smoother, reducing energy consumption, and improving the operational stability and durability of the equipment.

[0022] Further improvements, such as Figure 4 As shown: Several sets of balls are arranged between the bottom of the large gear disk 2 and the rotating groove 24. The design of the balls further reduces the contact area and friction between the large gear disk 2 and the rotating groove 24, making the rotation more flexible and reducing wear.

[0023] Furthermore, the innovative aspects of this solution will be explained.

[0024] Innovation of automatic feeding system: The drive motor 21 inside the base 1 drives the drive gear 3 to rotate and mesh with the large gear plate 2, so that the large gear plate 2 rotates in the rotating groove 24 through the rotating shaft 23. The insertion hole 18 on the large gear plate 2 cooperates with the insertion post 14 (the external spline 15 matches the keyway 19), which drives the ferrule connector 12 on the mounting plate 13 and the fixed seat 16 to rotate cyclically, so as to realize automatic feeding.

[0025] Rapid installation structure innovation: The mounting plate 13 is connected to the fixing hole 20 of the large gear plate 2 through the locking member 17, and the fixing seat 16 is fitted with the ferrule connector 12. Combined with the spline cooperation between the plug post 14 and the keyway 19, the ferrule connector 12 can be quickly disassembled and stably fixed.

[0026] Innovative cooling system: The cooling box 7 on the mounting base 6 sprays coolant onto the tapping head 9 through the cooling nozzle 10, reducing the machining temperature and minimizing tool wear and workpiece thermal deformation.

[0027] Low-friction rotation design: The bearing 22 at the connection between the rotating shaft 23 and the base 1, and the ball bearings between the bottom of the large gear plate 2 and the rotating groove 24, reduce rotational resistance and improve the stability of equipment operation.

[0028] Specifically, a comparison of relevant test data and practical application data for this solution.

[0029]

[0030]

[0031] Data Description

[0032] Processing time: This utility model uses the large gear plate 2 for automatic feeding, which reduces the time for manual loading and unloading, and shortens the processing cycle of a single workpiece by 1.2 seconds.

[0033] Machining error: The stable fixing of the locking part 17 and the fixed seat 16, together with the precise positioning of the tapping head 9, improves the accuracy of the internal thread, reducing the error from ±0.05mm to ±0.03mm.

[0034] Tool life: The cooling nozzle 10 continuously cools down the tool, reducing the wear rate and increasing the number of continuous machining cycles from 50 to 60, extending the tool life by 20%.

[0035] Temperature rise control: The cooling system effectively controls the processing temperature, reducing the temperature rise from 80℃ to 65℃, thus reducing the risk of workpiece thermal deformation.

[0036] Data Validity Statement

[0037] The experimental conditions were consistent: both groups of experiments used the same specification of ferrule connector 12 (made of 304 stainless steel), the same model of tapping head 9 (M10×1.5), and the processing parameters (rotation speed 1000r / min, feed rate 0.5mm / r) were kept consistent.

[0038] Replication validation: Each experiment was repeated 30 times, and the average value was used for calculation. Data fluctuation range ≤5% is considered statistically significant.

[0039] Equipment calibration: Before the experiment, parameters such as the speed of the drive motor 21, the displacement accuracy of the lifting rod 5, and the flow rate of the cooling box 7 are calibrated to ensure that the equipment is in a consistent state.

[0040] Working principle: The ferrule connector 12 is embedded into the fixed base 16. Through the matching of the insertion post 14 and the keyway 19, and the fixing of the locking member 17, the ferrule connector 12 is securely installed on the mounting plate 13. This step ensures the precise positioning and stable installation of the ferrule connector 12, providing a reliable foundation for subsequent processing. After the drive motor 21 starts, its power output drives the drive gear 3 to rotate. The drive gear 3 meshes with the teeth of the large gear plate 2, thereby driving the large gear plate 2 and the ferrule connector 12 mounted on it to rotate together. This step achieves automatic feeding of the ferrule connector 12, improving processing efficiency. The height of the lifting rod 5 is controlled by the lifting seat 4, ensuring that the tapping head 9 aligns and contacts the inner hole of the ferrule connector 12. This step ensures that the tapping head 9 can accurately enter the inner hole of the ferrule connector 12 for thread machining, avoiding processing errors caused by positional deviations. After the driver 8 starts, its power output drives the tool holder 11 and the tapping head 9 to rotate, performing thread machining on the inner hole of the ferrule connector 12. Simultaneously, the cooling system sprays coolant onto the tapping head 9 through the cooling nozzle 10, reducing heat during the machining process. This step achieves efficient and precise machining of the internal thread of the ferrule 12, while ensuring machining quality and tool life. After the internal thread of the ferrule 12 is machined, the large gear 2 continues to rotate, sending the machined ferrule 12 to the unloading area for unloading. This step achieves continuous and automated machining, improving production efficiency.
