Description

Technical Field

[0001] This invention relates to the field of polishing technology for hardware products, specifically to a high-efficiency polishing equipment and method for hardware products. Background Technology

[0002] Hardware products are widely used in modern industrial production and daily life, covering many categories such as tools, locks, kitchenware, and architectural decorative parts. In order to improve the appearance quality, gloss and surface performance of hardware products, polishing is an indispensable and important process. Polishing equipment usually adopts the principle of mechanical transmission, using a motor to drive polishing wheels, polishing belts and other polishing tools to rub the surface of hardware products at a certain speed and pressure, thereby removing burrs, scratches, oxide layers and other defects from the surface, so that the surface of hardware products reaches a smooth, flat and bright state.

[0003] A polishing device for processing hardware products, disclosed in existing patent number CN219310991 U, includes a base. A support component and a limiting component are installed on the upper surface of the base. A support frame is welded to the upper surface of the base. A guide rod is fixedly connected to the inner wall of the support frame. A polishing component is slidably arranged on the outside of the guide rod. The support component works in conjunction with the limiting component. The cylindrical hardware parts to be polished are inserted into the positioning ring. Under the limiting action of the positioning ring and the support of the platform, the workpiece is positioned. The polishing component is pushed along the guide rod, and the grinding wheel of the handheld polishing machine polishes the upper surface of the hardware parts. Therefore, it is not necessary to use clamping components to clamp the outer surface of the workpiece, thus avoiding the generation of indentations.

[0004] While the above method does not require clamping the workpiece surface, when polishing the end face of hollow cylindrical hardware products, only the cylindrical surface can be polished. The polishing process cannot reach the corners and edges of the cylinder, resulting in incomplete polishing of the entire end face and an inability to achieve a comprehensive and uniform polishing effect, affecting the overall appearance quality and refinement of the product. Furthermore, the unpolished corners and edges have a higher surface roughness, making them prone to stress concentration during subsequent use. When the product is subjected to external forces, these stress concentration areas are more susceptible to cracking and breakage, reducing the product's mechanical properties and service life. Moreover, for some hardware products with high surface quality and precision requirements, the roughness at the corners and edges will affect the fit and assembly quality with other components, thus interfering with the normal functioning of the product and reducing its overall performance and reliability.

[0005] Therefore, this invention proposes a highly efficient polishing equipment and method for hardware products to solve the above problems. Summary of the Invention

[0025] (III) Beneficial Effects

[0026] Compared with the prior art, the present invention provides a highly efficient polishing equipment and method for hardware products, which has the following beneficial effects:

[0027] 1. The corner polishing mechanism enables the simultaneous polishing of the inner and outer corners of the hollow cylindrical hardware product's end face while polishing the end face. This ensures complete polishing of the entire hardware product's end face, achieving a comprehensive and uniform polishing effect, improving the overall appearance quality and refinement of the product. Furthermore, it reduces stress concentration caused by rough edges, lowering the risk of cracks and breaks during use, enhancing product reliability. The corner polishing also improves the fit and assembly quality with other components, ensuring proper product function and enhancing overall performance.

[0028] 2. With the addition of elastic telescopic plates, the second polishing plates on both sides can automatically adjust themselves according to the diameter of the hollow cylindrical hardware product when they approach the corners of the end face. Regardless of the product diameter, the elastic telescopic plates can not only ensure stable contact between the second polishing plates and the corners, avoiding uneven polishing or omissions due to poor contact, but also reduce the equipment adjustment requirements due to changes in product size, reduce the difficulty of operation and the probability of errors, and improve the stability and reliability of equipment operation.

[0029] The connecting column and connecting ring enable the second polishing plate to automatically and synchronously move towards the end face corner of the hollow cylindrical hardware product while the first polishing plate is driven to approach the opposite side. This not only achieves synchronous movement of the first and second polishing plates, reducing the time and steps of driving the second polishing plate separately and improving polishing efficiency, but also eliminates the need for an additional power device to drive the second polishing plate, reducing the complexity and maintenance costs of the equipment.

[0030] 3. Through the set workpiece internal support mechanism, as the first polishing plate is driven to descend and approach the end face of the hollow cylindrical hardware product, the internal support plate is automatically pushed to move away from each other inside the hollow cylindrical hardware product, thus internally supporting and fixing the inner wall of the hollow cylindrical product. The automatic internal support function not only reduces the steps of manually adjusting the internal support plate, simplifies the operation process, and improves production efficiency, but also ensures that the hollow cylindrical hardware product remains stable during the polishing process, preventing product displacement or vibration caused by external forces.

[0031] 4. Through the design of the sliding groove, slider, and second spring, after the inner support plate comes into contact with hollow cylindrical hardware products of different diameters, as the first polishing plate continues to descend, it can push the slider to slide in the sliding groove, while simultaneously compressing the second spring. At this point, the inner support plate will stop moving. The design of the sliding groove, slider, and second spring not only allows the inner support plate to adapt to hollow cylindrical hardware products of different diameters, improving the versatility and flexibility of the inner support plate, but also ensures the stability of the inner support plate by stopping its movement after contacting the product, preventing product deformation or damage caused by excessive movement of the inner support plate.

[0044] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] This embodiment provides a high-efficiency polishing device for hardware products, such as... Figure 1 - Figure 8 As shown, the device includes a polishing table 1, a gantry frame 2 fixedly connected to the upper surface of the polishing table 1, a cylinder 3 fixedly connected to the center of the upper surface of the gantry frame 2, a lifting plate 4 fixedly connected to the output end, the lifting plate 4 being vertically slidably connected to the inside of the gantry frame 2, a frame 5 fixedly connected to the lower surface of the lifting plate 4, a drive motor 6 fixedly connected inside the frame 5, and also includes a corner polishing mechanism and a workpiece internal support mechanism. The corner polishing mechanism includes a turntable 7, which is fixedly connected to the output end of the drive motor 6. The turntable 7 has symmetrical through slots 802, and each through slot 802 has a symmetrically slidably connected moving block 803. Each of two adjacent moving blocks 803 is fixedly connected to a second polishing plate 809 on the opposite side. The corner polishing mechanism is used to polish the corners of the end face of hollow cylindrical hardware products.

[0046] In this embodiment, as Figure 2 and Figure 4As shown, each of the upper surfaces of the movable block 803 is rotatably connected to an elastic telescopic plate 804. Each of the two adjacent elastic telescopic plates 804 is rotatably connected to a connecting block 805 at the end away from the movable block 803. Each of the upper surfaces of the connecting blocks 805 is fixedly connected to a lifting column 806. Each of the outer surfaces of the lifting column 806 is slidably connected to a support block 807. Each of the support blocks 807 is fixedly connected to the side wall of the frame 5. When the lifting column 806 moves up and down on the outer surface of the support block 807, the elastic telescopic plates 804 can pull the movable blocks 803 closer to or further away from each other.

[0047] In this embodiment, as Figure 2 and Figure 3 As shown, the elastic telescopic plate 804 includes a hollow plate 8041 and an extension plate 8042. The extension plate 8042 is slidably connected to the hollow plate 8041. A first spring 8043 is fixedly connected between the extension plate 8042 and the hollow plate 8041. The end of the extension plate 8042 away from the hollow plate 8041 is rotatably connected to the side wall of the connecting block 805. The end of the hollow plate 8041 away from the extension plate 8042 is rotatably connected to the upper end of the moving block 803. When the connecting block 805 cannot move the moving block 803 by the elastic telescopic plate 804, the extension plate 8042 will slide out from the hollow plate 8041 and pull the first spring 8043 to adapt to the position of the moving block 803.

[0048] In this embodiment, as Figure 2 and Figure 4 As shown, a connecting ring 808 is fixedly connected between the upper ends of the two lifting columns 806. A connecting column 810 is symmetrically fixedly connected to the lower end of the connecting ring 808. The connecting columns 810 are slidably connected to the turntable 7. A first polishing plate 801 is fixedly connected between the lower ends of the two connecting columns 810. A counterweight 811 is fixedly connected to the upper end of the outer surface of the connecting column 810. When the first polishing plate 801 is limited and cannot continue to descend, the first polishing plate 801 will push the connecting column 810 to rise vertically on the turntable 7, and drive the lifting column 806 to rise synchronously through the connecting ring 808. Conversely, when the turntable 7 pulls the first polishing plate 801 to rise through the connecting column 810, the counterweight 811 connected to the outer surface of the connecting column 810 will first pull the connecting column 810 to descend until the counterweight 811 descends to the upper end of the turntable 7, and then pull the first polishing plate 801 to rise through the connecting column 810.

[0049] In existing technologies, when polishing the end face of hollow cylindrical hardware products, only the surface of the cylinder can be polished. The polishing process cannot reach the edges and corners, resulting in incomplete polishing of the entire end face and failing to achieve a comprehensive and uniform polishing effect, affecting the overall appearance quality and refinement of the product. Furthermore, the unpolished edges and corners have a higher surface roughness, making them prone to stress concentration during subsequent use. When the product is subjected to external forces, these stress concentration areas are more susceptible to cracking and breakage, reducing the product's mechanical properties and service life. Moreover, for some hardware products with high requirements for surface quality and precision, the roughness of the edges and corners will affect the fit and assembly accuracy with other components. Quality issues can interfere with the normal functioning of products, reducing their overall performance and reliability. Compared with existing technologies, this new technology can simultaneously drive the second polishing plate 809 to polish the inner and outer corners of the hollow cylindrical hardware product's end face while polishing the end face. This not only ensures the complete polishing operation of the entire hardware product's end face, achieving a comprehensive and uniform polishing effect and improving the overall appearance quality and refinement of the product, but also reduces stress concentration caused by roughness at the corners, lowering the risk of cracks and breaks during use, enhancing product reliability. Furthermore, the polishing treatment at the corners can improve the fitting accuracy and assembly quality with other components, ensuring the normal functioning of the product and improving overall performance.

[0050] At other levels, this embodiment also provides a workpiece internal support mechanism for automatically fixing a product from inside a hollow cylindrical product, such as... Figure 1 , Figure 4 - Figure 8 As shown, the workpiece internal support mechanism includes a worktable 901, which is fixedly connected to the upper end face of the polishing table 1. An annular groove 916 is provided at the center of the upper end face of the worktable 901. A circular ring 918 is slidably connected in the annular groove 916. A processing table 905 is fixedly connected to the upper end of the circular ring 918. Limiting grooves 915 are provided at equal intervals in an annular shape on the upper end face of the worktable 901. Arc-shaped grooves 909 are provided at equal intervals in an annular shape on the processing table 905. Linkage blocks 917 are slidably connected in each limiting groove 915. Linkage columns 910 are fixedly connected to the upper end of each linkage block 917. Linkage columns 910 are slidably connected in each arc-shaped groove 909. An internal support plate 911 is fixedly connected to the upper end of each linkage column 910.

[0051] In this embodiment, as Figure 6As shown, a fan-shaped rack 906 is fixedly connected to both sides of the outer surface of the processing table 905. A rack plate 907 is meshed with the side of the fan-shaped rack 906 away from the processing table 905. A connecting frame 908 is fixedly connected to the side of the rack plate 907 away from the fan-shaped rack 906. A sliding column 902 is fixedly connected to the side of the connecting frame 908 near the gantry 2. The sliding column 902 is slidably connected to the gantry 2. When the sliding column 902 slides on the gantry 2 and pushes the connecting frame 908 to move, the connecting frame 908 will drive the rack plate 907 to move the fan-shaped rack 906, so that the processing table 905 rotates.

[0052] In this embodiment, as Figure 7 As shown, each of the sliding columns 902 has a sliding groove 912 on its outer surface, and each of the sliding columns 902 has a slider 913 fitted on its outer surface. The sliders 913 are slidably connected to the outer surface of the sliding column 902 through the sliding groove 912. A second spring 914 is fixedly connected between the slider 913 and the connecting frame 908. The second spring 914 is fitted on the outer surface of the sliding column 902. A push plate 903 is rotatably connected to the upper end of each slider 913. A vertical plate 904 is rotatably connected to the end of the push plate 903 away from the slider 913. The vertical plate 904 is fixedly connected to the lower end of the lifting plate 4. When the slider 913 cannot push the connecting frame 908 to move through the second spring 914, the slider 913 will slide in the sliding groove 912 as the slider 913 is continuously subjected to force, and at the same time, it will squeeze the second spring 914 connected between the slider 913 and the connecting frame 908.

[0053] Compared with existing technologies, this technology can automatically push the inner support plates 911 to move away from each other inside the hollow cylindrical hardware product as the first polishing plate 801 descends and approaches the end face of the hollow cylindrical hardware product. This provides internal support and fixation to the inner wall of the hollow cylindrical product. The automatic internal support function not only reduces the steps of manually adjusting the inner support plates 911, simplifies the operation process, and improves production efficiency, but also ensures that the hollow cylindrical hardware product remains stable during the polishing process, preventing product displacement or vibration caused by external forces.

[0054] In other aspects, this embodiment also provides an efficient method for polishing hardware products, such as... Figure 1 - Figure 8 As shown, it includes the following steps:

[0055] Step 1: Clean the surface of the hollow cylindrical hardware product to remove oil, iron filings, and dust;

[0056] Step 2: Inspect the surface of the hollow cylindrical hardware product and repair or treat any defects such as scratches, dents, and cracks.

[0057] Step 3: Place the hollow cylindrical hardware product on the polishing area, and then use a clamp to fix the hollow cylindrical hardware product in place;

[0058] Step 4: Start the polishing equipment, appropriately reduce the speed and pressure of the polishing equipment, and then polish the surface of the hollow cylindrical hardware product;

[0059] Step 5: Use a surface roughness tester to check the surface quality after polishing. Once the quality is qualified, perform a final cleaning of the polished product to remove polishing liquid residue and polishing dust from the surface.

[0060] In this embodiment, during the polishing process of the hollow cylindrical hardware product in step 4, attention should also be paid to the corners of the hollow cylinder, and the corners should be polished and ground simultaneously.

[0061] In this embodiment, during the polishing process of the hollow cylindrical hardware product in step 4, different polishing tools can be used to perform coarse polishing, medium polishing, and fine polishing on the hollow cylindrical hardware product respectively.

[0062] The overall working process and principles involved in the above embodiments are as follows:

[0063] When polishing hollow cylindrical hardware products, the product is first placed on the upper surface of the processing table 905. Then, the cylinder 3 is driven to push the lifting plate 4 vertically downward on the gantry 2. Since the lower surface of the lifting plate 4 is fixedly connected to the frame 5, and the frame 5 houses the drive motor 6, the output end of the drive motor 6 is connected to the turntable 7, and the first polishing plate 801 is set below the turntable 7, as the lifting plate 4 descends, it will drive the first polishing plate 801 to descend synchronously through the frame 5, the drive motor 6, and the turntable 7, so that the first polishing plate 801 approaches the hardware product below. When the first polishing plate 801 contacts the upper surface of the hardware product, as the lifting plate 4 continues to move downward, the product will be polished. As the first polishing plate 801 descends, it is blocked by the hardware product and moves upward, approaching the turntable 7. This pushes the connecting column 810 connected to the upper end of the first polishing plate 801 to slide vertically upward on the turntable 7, and causes the connecting ring 808 connected to the upper end of the connecting column 810 to rise synchronously. When the first polishing plate 801 contacts the end face of the hardware product, the two adjacent second polishing plates 809 will be positioned inside and outside the hollow cylindrical hardware product, respectively. At this time, as the connecting ring 808 rises, it pulls the lifting column 806 to slide vertically upward on the support block 807, causing the connecting block 805 connected to the lower end of the lifting column 806 to rise synchronously. Both sides of the connecting block 805 are rotatably connected to elastic telescopic plates 804. A movable block 803 is connected to the end of the elastic telescopic plate 804 away from the connecting block 805. The movable block 803 is slidably connected within the through groove 802, and the second polishing plate 809 is fixedly connected to the side wall of the movable block 803. Therefore, as the connecting block 805 rises, the connecting block 805 will pull the two movable blocks 803 together through the elastic telescopic plates 804, causing them to slide closer to each other within the through groove 802. This causes the second polishing plate 809 to move horizontally closer to the end face corner of the hollow cylindrical hardware product. Since the elastic telescopic plate 804 is composed of a hollow plate 8041, an extension plate 8042, and a first spring 8043, the elastic telescopic plate 804... 04 During the process of pulling the second polishing plate 809 closer to the corner of the hollow cylindrical hardware product by the moving block 803, when one of the second polishing plates 809 is close to the corner while the other second polishing plate 809 is not in contact, the elastic telescopic plate 804 will adapt to change until the other second polishing plate 809 also contacts the corner. No matter how the product diameter changes, the elastic telescopic plate 804 can not only ensure the stable contact between the second polishing plate 809 and the corner, avoiding uneven polishing or omissions caused by poor contact, but also reduce the equipment adjustment requirements caused by changes in product size, reduce the difficulty of operation and the probability of error, and improve the stability and reliability of equipment operation.

[0064] During the descent of the lifting plate 4, the lifting plate 4 will push the vertical plates 904 symmetrically connected to its lower end face to descend synchronously. Since each of the lower end faces of the vertical plates 904 is rotatably connected to a push plate 903, and each of the push plates 903 is rotatably connected to a slider 913 at the end away from the vertical plate 904, and the sliders 913 are slidably connected to the outer surface of the slide column 902 through the slide groove 912, and a second spring 914 is connected between the sliders 913 and the connecting frame 908, as the vertical plate 904 descends, the vertical plate 904 will push the sliders 913 through the push plate 903. The movement is synchronized, and the slider 913 is hindered by the second spring 914 connected to the connecting frame 908, which will preferentially push the connecting frame 908 to move, and pull the sliding column 902 to slide on the gantry 2. During the movement of the connecting frame 908, the connecting frame 908 will drive the rack plate 907 to move synchronously. Since the rack plate 907 is connected to the processing table 905 through the meshing of the sector rack 906, and the processing table 905 is rotatably connected to the worktable 901 through the annular groove 916 and the ring 918, Therefore, as the rack plate 907 moves, it will drive the fan-shaped rack 906 to rotate the machining table 905 on the upper surface of the worktable 901. During the rotation of the machining table 905, the position of the annularly spaced arc-shaped grooves 909 will change, causing the arc-shaped grooves 909 to press against the slidingly connected linkage column 910 inside, pushing the linkage column 910 to slide along the arc-shaped groove 909. As the linkage column 910 slides along the arc-shaped groove 909, the linkage column... 910 will drive the linkage block 917 to slide in the limiting groove 915 opened on the upper surface of the worktable 901. At the same time, it will drive the inner support plate 911 connected to the upper end of the linkage column 910 to move horizontally away from each other, so as to internally support and fix the hollow cylindrical hardware product. The automatic internal support function not only reduces the steps of manually adjusting the inner support plate 911, simplifies the operation process, and improves production efficiency, but also ensures that the hollow cylindrical hardware product remains stable during the polishing process, preventing product displacement or vibration caused by external force.

[0065] When the inner support plate 911 comes into contact with the inner wall of the hollow cylindrical hardware product, as the lifting plate 4 drives the vertical plate 904 to continue to descend, the lifting plate 4 will push the slider 913 to slide in the groove 912 opened on the outer surface of the sliding column 902, and squeeze the second spring 914 between the slider 913 and the connecting frame 908. The connecting frame 908 will not continue to move due to the rebound force of the second spring 914. At this time, the inner support plate 911 will not continue to move. The design of the groove 912, the slider 913 and the second spring 914 not only allows the inner support plate 911 to adapt to hollow cylindrical hardware products of different diameters, improving the versatility and flexibility of the inner support plate 911, but also ensures the stability of the inner support by stopping after contacting the product, preventing product deformation or damage caused by excessive movement of the inner support plate 911.

[0066] After the inner support plate 911 provides internal support and fixation for the hardware product, and the first polishing plate 801 and the second polishing plate 809 respectively contact the end face and corners of the hardware product, the operator can turn on the drive motor 6 to drive the turntable 7 connected to the output end of the drive motor 6 to rotate. The turntable 7, through the connecting column 810 and the moving block 803, will drive the first polishing plate 801 and the second polishing plate 809 to rotate synchronously, so that the first polishing plate 801 and the second polishing plate 809 polish the end face and corners of the hardware product respectively. This not only ensures that the polishing operation of the entire end face of the hardware product is complete, achieving a comprehensive and uniform polishing effect, improving the overall appearance quality and refinement of the product, but also reduces stress concentration caused by the roughness of the corners, reducing the risk of cracks and breaks during use, enhancing the reliability of the product. Furthermore, the polishing treatment of the corners can improve the fit accuracy and assembly quality with other components, ensuring the normal functioning of the product and improving the overall performance.

[0067] After polishing the end face and corners of the hardware product, the operator can drive the cylinder 3 to pull the lifting plate 4 to rise. Through the frame 5, drive motor 6, turntable 7 and connecting column 810, the first polishing plate 801 moves upward synchronously. Due to the weight of the counterweight block 811 connected to the outer surface of the connecting column 810, during the process of the turntable 7 driving the first polishing plate 801 to rise, the counterweight block 811 will first push the connecting column 810 to descend vertically on the turntable 7, pulling the connecting ring 808 to descend. Through the lifting column 806, connecting block 805, elastic telescopic plate 804 and moving block 803, the second polishing plate 809 is separated from the edge of the hardware product. When the counterweight block 811 descends to the upper surface of the turntable 7, as the turntable 7 continues to rise, the turntable 7 will pull the first polishing plate 801 to rise synchronously through the connecting column 810 and separate from the hardware product.

[0068] During the upward movement of the lifting plate 4, the lifting plate 4 will pull the processing table 905 to rotate in the opposite direction through the vertical plate 904, push plate 903, slider 913, second spring 914, sliding column 902, connecting frame 908 and rack plate 907. This will drive the linkage column 910 to drive the linkage block 917 to slide in the opposite direction in the limit groove 915, causing the inner support plate 911 to move closer to each other and separate from the inner wall of the hollow cylindrical hardware product. This will automatically release the inner support fixing of the hardware product, allowing the staff to take out the hardware product.
