[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Referring to Figures 1-3, one embodiment of this utility model provides a bicycle hub component production device, including a support plate 1. A first motor 2 is fixedly connected to the middle of the support plate 1. A first sealing ring 3 is fixedly connected to the upper side of the support plate 1 outside the first motor 2. A mounting base 4 is rotatably connected to the inner side of the first sealing ring 3. The drive end of the first motor 2 is rotatably connected to the bottom of the mounting base 4. A second sealing ring 5 is fixedly connected to the outer side of the mounting base 4. The lower side of the second sealing ring 5 is tightly fitted with the upper wall of the first sealing ring 3. An L-shaped plate 6 is fixedly connected to the rear end of the support plate 1. A hydraulic rod 7 is installed on the top of the L-shaped plate 6 through an adjustment structure. A base 8 is fixedly connected to the drive end of the hydraulic rod 7. A second motor 9 is fixedly connected to the inner side of the base 8. A rotating rod 10 is fixedly connected to the drive end of the second motor 9. A cutter 11 is fixedly connected to the lower end of the rotating rod 10. A protective cover 13 is provided on the outer side of the rotating rod 10. A connecting plate 12 is fixedly connected to the upper side of the base 8. The upper end of the connecting plate 12 is fixedly connected to the lower side of the base 8. The front and rear sides of the upper end of the protective cover 13 are fixedly connected to the nozzles 18. The top of the L-shaped plate 6 is provided with a first movable plate 19 that slides back and forth. An electric push rod 20 is fixedly connected to the rear side of the top of the L-shaped plate 6. The driving end of the electric push rod 20 is fixedly connected to the rear side of the first movable plate 19. The upper end of the hydraulic rod 7 is fixedly connected to the middle of the first movable plate 19. A through hole 21 is opened on the upper side of the bearing plate 1 outside the first sealing ring 3. A retaining ring 22 is fixedly connected on the upper side of the bearing plate 1 outside the through hole 21.

[0032] The hub parts to be processed are placed on top of the mounting base 4. The hydraulic rod 7 pushes the machine base 8 and the second motor 9 downward, causing the rotating rod 10 and the cutting tool 11 to approach the workpiece. The second motor 9 starts, driving the cutting tool 11 to rotate at high speed to perform milling, drilling, and other processing on the workpiece. The electric push rod 20 pushes the first movable plate 19 to move back and forth, allowing the cutting tool 11 to perform precise cutting along the workpiece surface or adjust its position to ensure processing accuracy. During processing, the nozzle 18 connected to the cooling system sprays coolant onto the contact area between the cutting tool 11 and the workpiece to prevent the cutting tool 11 from overheating and extend its life. The protective cover 13, which is fixed to the machine base 8 via the connecting plate 12, moves with the movement of the cutting tool 11. The protective cover 13 descends with the cutting tool 11, covering the processing area and preventing coolant splashing. The splashed coolant is blocked by the inner wall of the protective cover 13 and flows along the second sealing ring 5 to the bearing plate 1. After being guided by the retaining ring 22, it is discharged and recovered through the through hole 21. After processing is completed, the hydraulic rod 7... Raising the cutting tool 11 and the protective cover 13 exposes the workpiece for easy handling, thereby preventing coolant splashing during machining and reducing the difficulty of subsequent cleaning.

[0033] Referring to Figures 3-5, a scraper ring 17 is provided inside the protective cover 13. The outer wall of the scraper ring 17 is in close contact with the inner wall of the protective cover 13. An annular groove 14 for receiving the scraper ring 17 is provided at the top of the inner wall of the protective cover 13. A fixing plate 15 is fixedly connected to the outside of the hydraulic rod 7. A movable rod 16 is fixedly connected to the outer end of the fixing plate 15. The lower end of the movable rod 16 passes through the top of the protective cover 13 and is fixedly connected to the upper side of the scraper ring 17.

[0034] After processing, the hydraulic rod 7 lifts the tool 11 and the protective cover 13, exposing the workpiece for loading and unloading. The scraper ring 17 is fixed to the upper outside of the hydraulic rod 7 via the movable rod 16 and the fixed plate 15, and remains stationary. When the protective cover 13 rises, the scraper ring 17 fixed on the hydraulic rod 7 remains stationary and moves relative to the inner wall of the protective cover 13 to scrape off residual coolant and metal debris, reducing residue.

[0035] Referring to Figures 1, 6, and 7, the upper end of the mounting base 4 has a cross-shaped opening 23.

[0036] A housing 24 is fixedly connected to the inner center of 23, and limit rods are fixedly connected to all four sides of the outer wall of the housing 24.

[0037] 25. A second movable plate 26 is slidably provided on the outside of the limiting rod 25. A clamping plate 27 for fixing accessories is fixedly connected to the top of the second movable plate 26. A connecting bolt 31 is rotatably connected to the top of the outer casing 24.

[0038] The lower end of the bolt 31 is fixedly connected to a large helical gear 30. The middle part of the outer casing 24 is rotatably connected to a lead screw 28. The outer end of the lead screw 28 is threadedly connected to the middle part of the second movable plate 26. The inner end of the lead screw 28 is fixedly connected to a small helical gear 29. The outer side of the small helical gear 29 is meshed with the upper side of the large helical gear 30.

[0039] Place the hub parts to be processed on top of the mounting base 4. Use a tool to rotate the connecting bolt 31, which drives the large helical gear 30 to rotate. The large helical gear 30 meshes with the small helical gears 29 around it, driving the lead screw 28 to rotate. The second movable plate 26 is restricted by the limit rod 25 and can only move horizontally. Thus, the rotating lead screw 28 pushes the second movable plate 26 to slide along the limit rod 25, so that the clamping plate 27 clamps the workpiece from the outside or inside, ensuring stability during processing.

[0040] Working principle: The accessory is placed on top of the mounting base 4. A tool drives the connecting bolt 31 to rotate, which in turn drives the large helical gear 30. The large helical gear 30 then drives the lead screw 28 to rotate, which in turn moves the second movable plate 26 and the clamping plate 27, clamping and fixing the accessory from the outside or inside. Subsequently, the hydraulic rod 7, via the machine base 8, drives the second motor 9, the rotating rod 10, and the cutting tool 11 to descend, bringing the cutting tool 11 into contact with the accessory. The second motor 9 is then activated, driving the rotating rod 10 and the cutting tool 11 to rotate, processing the accessory. The electric push rod 20 drives the first movable plate 19 to move back and forth, thereby moving the cutting tool 11 back and forth to process the accessory. Simultaneously, as the machine base 8 lowers the cutting tool 11, the connecting plate 12 lowers the protective cover 13, covering the cutting tool 11 and the upper end of the mounting base 4. During processing, the spray nozzle 18, connected to the cooling system, provides cooling. Coolant flows out to prevent the tool 11 from overheating during processing. The protective cover 13 prevents coolant from splashing up from the tool 11. The blocked coolant flows downward and through the second sealing ring 5 to the support plate 1. It is blocked by the retaining ring 22 and will not spread. It flows downward through the through hole 21 and is collected. After processing is completed, the hydraulic rod 7 drives the tool 11 and the protective cover 13 to rise, exposing the parts. During the rising process, the scraper ring 17 inside the protective cover 13 is fixed to the upper outside of the hydraulic rod 7 by the movable rod 16 and the fixed plate 15 and remains stationary. As the protective cover 13 rises, the side wall of the protective cover 13 is cleaned.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
