Description

Technical Field

[0002] In the hardware manufacturing industry, hardware parts are widely used in various sectors such as automotive, aerospace, construction machinery, electronics, and building materials due to their excellent mechanical properties, durability, and wide applicability. Polishing, as a key post-processing step in hardware parts manufacturing, aims to remove burrs, oxide scale, machining marks, and other defects from the surface of hardware parts, improving surface smoothness, flatness, and aesthetics. Simultaneously, it enhances the corrosion resistance and service life of the hardware parts, ensuring subsequent assembly accuracy and reliability.

[0003] With the improvement of industrial automation and the increasing demands for hardware quality, traditional hardware polishing processes have gradually revealed many shortcomings, especially for tubular, cylindrical, and sleeve-shaped hardware with internal and external wall structures. Existing polishing methods are unable to meet the requirements for efficient and uniform processing. Currently, polishing for such hardware has the following drawbacks: First, both loading and unloading require manual intervention, resulting in high labor intensity and low work efficiency. Second, existing polishing equipment mostly adopts a step-by-step polishing mode, that is, first polishing the outer wall of the hardware manually or with a single machine, and then changing equipment or adjusting tooling to polish the inner wall. This results in low work efficiency, an inability to perform simultaneous adjustments and polishing, poor applicability, and an inability to meet actual usage needs.

[0004] Therefore, there is a need for a device for simultaneous polishing of the inner and outer walls of hardware parts, which aims to solve the above problems. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] See Figures 1-9 A device for synchronous polishing of inner and outer walls of metal parts includes a loading table 1, a processing table 24 installed on one side of the loading table 1, an inclined surface 3 for tilting multiple cylindrical metal parts 2 on the loading table 1, and a loading receiving rod 19 for receiving the cylindrical metal parts 2 fixedly installed on the loading table 1. The device also includes: The feeding mechanism is installed on the feeding platform 1 and is used to feed and unload multiple inclined cylindrical hardware parts 2 one by one. The feeding mechanism includes cylindrical hardware parts 2 for pushing and a first connecting rod 6, a second connecting rod 14 and a third connecting rod 17 for pushing. A push rod 5 is fixedly installed at one end of the first connecting rod 6. The feeding platform 1 is provided with a push groove 4 for pushing the material from the rear and for unloading and avoiding obstruction. The push rod 5 is pushed and fed by the traction of the second connecting rod 14 and the third connecting rod 17.

[0029] Furthermore, the feeding mechanism also includes a first motor 18 for driving the second link 14 and the third link 17 to perform traction. One end of the second link 14 is rotatably connected to the first link 6 via the first connecting shaft 13 and is located in the middle of the first link 6. The other end of the second link 14 is rotatably connected to the unloading platform 1 via the second connecting shaft 15. The other end of the first link 6 is rotatably connected to one end of the third link 17 via the third connecting shaft 16. The other end of the third link 17 is fixedly connected to the output shaft of the first motor 18. The first motor 18 is fixedly installed on the unloading platform 1.

[0030] Furthermore, the feeding mechanism also includes a slider 9 for limiting the direction of the travel section of the feeding rod 5. The feeding platform 1 is provided with a feeding groove 7 for guiding and connecting the feeding rod 5. The feeding groove 7 is provided with a sliding groove 8 adapted to slide and connect the slider 9. The slider 9 is fixedly connected to a limiting plate 12 by a traction rod 10. The first connecting rod 6 is provided with a traction groove 11 adapted to slide and connect the traction rod 10.

[0031] Preferably, during the blanking and feeding of the cylindrical hardware part 2, the output shaft of the first motor 18 drives the third connecting rod 17 to rotate. Under the traction rotation of the third connecting shaft 16 and the second connecting rod 14, the first connecting rod 6 drives the material-pulling rod 5 to move around the material-pulling groove 7 opened on the blanking table 1. Since the first connecting rod 6 is limited and guided by the traction rod 10 on the slider 9, the first connecting rod 6 is always in contact with the outside of the blanking table 1, and the material-pulling rod 5 on the first connecting rod 6 is... The material feeder slides counterclockwise along the trajectory of the feeding groove 7. Since the push groove 4 on the unloading table 1 completes the unloading of the cylindrical hardware 2 to the end side of the unloading receiving rod 19, when the feeding rod 5 moves to the push groove 4 along the trajectory, it can push the end side of the cylindrical hardware 2 to move closer to the processing table 24, so that the next polished cylindrical hardware 2 can be pushed out. The next unprocessed cylindrical hardware 2 can be pushed to the upper position of the processing table 24 for subsequent polishing.

[0032] As the feeding rod 5 slides counterclockwise along the trajectory opened at the feeding groove 7, when the feeding rod 5 pushes the cylindrical hardware 2 placed on the unloading receiving rod 19 to the processing table 24, the feeding rod 5 slides along the trajectory to the upper side of the feeding groove 7, thus avoiding interference with the unloading of the cylindrical hardware 2 on the inclined surface 3. This cycle can be repeated to complete the continuous feeding operation in a corresponding period.

[0033] This feeding method avoids positioning interference caused by multiple workpieces entering the processing station simultaneously, improving processing positioning accuracy. It also enables efficient collaboration between workpiece transfer and polishing, building a continuous production process and significantly improving the overall processing efficiency of batch cylindrical hardware parts. Furthermore, it achieves fully automated operation from workpiece unloading, loading, positioning to unloading after processing, greatly reducing the intensity of manual operation, improving the safety and standardization of the production process, and facilitating production and processing.

[0034] like Figures 1 to 8 As shown, this embodiment, based on the above embodiment, also includes a receiving mechanism, which is movably mounted on the processing table 24 for receiving and collecting the polished cylindrical hardware parts 2. The receiving mechanism includes a receiving box 25 and a flip plate 33 for assisting in receiving. The flip plate 33 is rotatably mounted on the receiving box 25 via a fifth connecting shaft 34. A reset coil spring 35 for elastic rotation and reset is provided at the connection between the fifth connecting shaft 34 and the receiving box 25. The inner and outer wall polishing mechanism is installed on the receiving box 25 and is used to simultaneously polish the inner and outer walls of the cylindrical hardware parts 2 that are fed in.

[0035] Furthermore, the receiving mechanism also includes a second electric push rod 29 and a push rod 32 for driving the flipping of the flap 33. The push rod 32 is fixedly installed on the push plate 30, and the push plate 30 is fixedly connected to the piston rod of the second electric push rod 29. The second electric push rod 29 is fixedly installed on the receiving box 25, and a storage frame 28 for collecting materials is provided on one side of the flap 33.

[0036] Furthermore, the receiving mechanism also includes a first electric push rod 26 for driving the movement of the receiving box 25. The receiving box 25 is fixedly connected to the piston rod of the first electric push rod 26. The first electric push rod 26 is fixedly installed inside the unloading platform 1. The processing platform 24 is provided with an installation slot 27 for storing the receiving box 25. The receiving box 25 is provided with a protective pad 31 for protection.

[0037] Furthermore, the inner and outer wall polishing mechanism includes a polishing wheel 39 for polishing the inner and outer walls. The polishing wheel 39 is fixedly connected to the output shaft of the third motor 38. The third motor 38 is fixedly connected to the piston rod of the third electric push rod 37. The third electric push rod 37 is fixedly installed on the support frame 36. The support frame 36 is fixedly installed on one side of the receiving box 25.

[0038] Furthermore, the inner and outer wall polishing mechanism also includes a drive roller 20 for polishing auxiliary rotation of the cylindrical hardware 2 being fed. The drive roller 20 is rotatably mounted on the support base 23 via the fourth connecting shaft 21. The support base 23 is fixedly mounted on the processing table 24. The fourth connecting shaft 21 is fixedly connected to the output end of the second motor 22. The second motor 22 is fixedly mounted inside the unloading receiving rod 19.

[0039] Preferably, in this embodiment, when the cylindrical hardware 2 on the receiving rod 19 is pushed onto the drive roller 20, the output shaft of the second motor 22 drives the drive roller 20 on the fourth connecting shaft 21 to rotate, thereby driving the cylindrical hardware 2 to rotate. At this time, the output shaft of the third motor 38 drives the polishing wheel 39 to rotate, and the third electric push rod 37 drives the already rotated polishing wheel 39 to move closer to the cylindrical hardware 2, thereby completing the polishing of the inner and outer walls of the cylindrical hardware 2. After the cylindrical hardware 2 is polished, the first electric push rod 26 drives the receiving box 25 and the support frame 36 to move outward. Due to the advancement of the push rod 5, the polished cylindrical hardware 2 randomly falls into the receiving box 25 for storage.

[0040] When the first electric push rod 26 drives the receiving box 25 to reset and store, the polishing wheel 39 on the support frame 36 can then polish the repositioned cylindrical hardware 2. Meanwhile, the corresponding second electric push rod 29 drives the push plate 30 and push rod 32 to extend and push towards the flip plate 33, thereby facilitating the pushing of the polished cylindrical hardware 2 in the receiving box 25 to the storage frame 28 for collection. This eliminates the need for manual loading and unloading, significantly improving the polishing efficiency of the hardware.

[0041] This method of polishing both the inner and outer walls and collecting materials effectively ensures the continuity of processing, reduces the frequency of manual intervention, minimizes efficiency fluctuations caused by inconsistent manual operation rhythms, significantly improves the overall processing efficiency of batch cylindrical hardware parts, and allows for automatic unloading and collection after polishing, ensuring processing continuity and workpiece cleanliness. It is suitable for large-scale batch production scenarios and effectively optimizes production management efficiency.

[0042] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
