Description

Technical Field

[0001] This invention relates to the field of hardware accessories polishing technology, and in particular to a polishing device for hardware accessories production and processing. Background Technology

[0002] Hardware fittings refer to basic metal components used to achieve functions such as connection, fastening, support, and decoration. Grinding is one of the common processes in hardware fitting manufacturing. Currently, the grinding operations for hardware fittings in the industry mainly include the following methods: Manual hand-held polishing: This method is not only labor-intensive and generates serious dust hazards, but the polishing quality also depends entirely on the worker's skill level, resulting in poor consistency and making it difficult to meet the needs of high-precision, high-volume production.

[0003] Fixed-position grinding machines: These machines use specialized fixtures to hold the workpiece in place and operate with fixed grinding wheels or heads. While these machines offer stable processing, they lack flexibility. When dealing with complex workpieces with multiple surfaces to be ground (such as simultaneously grinding the top, sides, and chamfers), complex flipping mechanisms or multiple clamping operations are often required. Frequent loading and unloading not only reduces production efficiency but also causes repeated positioning errors that severely affect the dimensional accuracy of the final product.

[0004] Existing multi-axis linkage grinding equipment: High-end equipment typically uses a six-axis robotic arm in conjunction with a vision system. Although it offers high flexibility, the equipment is expensive to manufacture and maintain, resulting in a low return on investment for standard hardware manufacturers with relatively low profit margins, making it difficult to popularize. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for the production and processing of hardware accessories.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A grinding device for manufacturing and processing hardware accessories includes: a center seat, a turntable rotatably mounted on the center seat, a carrier mechanism circumferentially distributed around the rotation center of the turntable on the turntable, the carrier mechanism including a ball seat, a spherical platform movably mounted inside the ball seat, a central column in the middle of the spherical platform, a carrier fixed on the top of the central column, and a clamping component for fixing hardware accessories on the carrier. An angle adjustment mechanism for adjusting the tilt angle of the spherical table is provided below the turntable; a mounting base is installed on the top of the center seat, and a grinding mechanism is installed on the mounting base; The central seat is equipped with a rotation drive mechanism for driving the turntable to rotate. The rotation drive mechanism controls the turntable to rotate, so that the carrier mechanism moves periodically between the grinding station and other stations.

[0007] As a preferred embodiment of the present invention: the angle adjustment mechanism includes a lifting control component, a first angle adjustment component, and a second angle adjustment component. The first angle adjustment component is controlled by the lifting control component to switch between a working position and a standby position. The first angle adjustment component includes a first arc-shaped frame, on which a second arc-shaped frame is slidably mounted. A first adjustment motor is mounted at the bottom of the second arc-shaped frame. The first arc-shaped frame has first protruding teeth distributed along an arc-shaped path. A first gear is mounted at the output end of the first adjustment motor, and the first gear meshes with the first protruding teeth.

The movement paths of the second arc-shaped frame and the slide block are orthogonal in a top-view perspective, and in the working position, the movement centers of the movement paths of the second arc-shaped frame and the slide block coincide with the center of the spherical table. A connecting component is installed on the slide block. The central column in the middle of the spherical stage extends downward to the bottom of the spherical stage. When the carrier mechanism is in the grinding station, it operates based on the lifting control component. When the first angle adjustment component and the second angle adjustment component rise to the working position, the connecting component couples with the central column.

[0008] As a preferred embodiment of the present invention: the connecting assembly includes a rotation control motor, which is mounted on a slide. A rotating head is mounted on the output end of the rotation control motor. A slot adapted to the rotating head is provided at the bottom end of the central column.

A lifting control motor is fixed on one of the uprights of the base frame. A lifting control screw is installed at the output end of the lifting control motor. One end of the lifting control screw is rotatably installed on the base frame.

[0010] As a preferred embodiment of the present invention: a limiting bracket is provided below the turntable, the limiting bracket being concentrically arranged with one large and one small bracket, the limiting bracket having an opening at the grinding station, and a mounting plate fixed to the outer side of the bottom of the central column of the spherical table, with ball bearings movably arranged on the mounting plate, the ball bearings rolling on the limiting bracket when the turntable rotates.

[0011] As a preferred embodiment of the present invention: a fixed frame is fixed on the base frame, and an arc-shaped plate is slidably mounted on both the fixed frame and the center seat. The end of the arc-shaped plate has an arc-shaped structure adapted to the limiting bracket. The arc-shaped plate is connected to its mounting surface by a spring. The arc-shaped plate extends into the opening of the limiting bracket based on the spring support and cooperates with the limiting bracket to form a closed-loop structure. A crossbar is fixed on the arc-shaped plate, and a lever is fixed on the lifting frame. A wedge block is fixed on the top of the lever, and the crossbar is located on the movement path of the wedge block. When the first angle adjustment component and the second angle adjustment component rise to the working position, the wedge block at the top of the lever pushes the arc-shaped plate to both sides.

[0012] As a preferred embodiment of the present invention, a rubber ring is fixed on the ball seat, and the rubber ring is in contact with the spherical platform.

[0013] As a preferred embodiment of the present invention: the clamping assembly includes a clamping frame, and a circumferentially distributed strip groove is formed on the top of the carrier. The center line of the strip groove and the central axis of the central column both intersect at the center of the carrier. The clamping frame is slidably installed in the strip groove. Preferably, there are three clamping frames. A central column is fixed on the clamping frame. An annular frame is rotatably installed on the carrier. The annular frame has arc-shaped grooves with the same number and position as the central columns, and each central column extends into the corresponding arc-shaped groove. The distance between the arc-shaped groove and the center of the carrier gradually decreases in a clockwise or counterclockwise direction. An operating handle is fixed on the annular frame. A side bracket is fixed on one side of the carrier. A threaded knob is threadedly connected to the side bracket. A pressure plate is fixed at the bottom of the threaded knob and is located above the annular frame.

[0014] As a preferred embodiment of the present invention: the rotation drive mechanism includes a turntable control motor, a third convex tooth arranged in a circular pattern is provided on the turntable, and a turntable control gear is installed at the output end of the turntable control motor, the turntable control gear meshing with the third convex tooth.

[0015] As a preferred embodiment of the present invention: a lubrication mechanism is provided on one side of the center seat. The lubrication mechanism includes a lubricating fluid supply device and a mounting bracket. The output end of the lubricating fluid supply device is connected to a nozzle through a connecting pipe. The nozzle is fixed on the mounting bracket, and the output end of the nozzle extends to one side of the conveying path of the spherical table. A micro-groove is provided on the side of the rubber ring near the spherical table.

[0016] The beneficial effects of this invention are as follows: 1. This invention, by setting up a carrier mechanism and an angle adjustment mechanism, can fix hardware parts on the carrier mechanism, use a turntable to transport the hardware parts to the grinding station, and use the grinding mechanism for grinding. During the process, the angle adjustment mechanism can be used to control the movement of the spherical table within the ball seat to change the posture of the hardware parts to meet different grinding needs. Due to the high degree of freedom of movement of the spherical table, it can better realize the grinding operation of hardware parts at different angles.

[0017] 2. By setting ball bearings and limiting brackets, the present invention can reliably support the carrier mechanism when the turntable is transporting the carrier mechanism, thereby avoiding structural skewing. The opening set in the limiting bracket at the grinding station can provide space for the movement of the spherical table.

[0018] 3. This invention, by setting up structures such as arc-shaped plates and levers, can achieve stable support for the carrier assembly during transportation by utilizing the limiting bracket and the arc-shaped plate, thus preventing structural tilting. Simultaneously, when grinding is required, the lifting frame is raised, and as the rotating head inserts into the slot of the central column, the wedge-shaped block at the top of the lever pushes the arc-shaped plate to both sides, providing space for angle adjustment. After grinding, the angle adjustment mechanism controls the structure to return to center, the lifting mechanism controls the structure to reset, and as the rotating head separates from the slot of the central column, the arc-shaped plate resets based on spring rebound force. Due to the guide bevel, the arc-shaped plate can smoothly move to the bottom of the mounting plate, providing support for it.

[0019] 4. By setting a rubber ring, the present invention can keep the spherical table as stable as possible when it is not subjected to external force, so that the rotating head can be inserted into the slot at the bottom of the central column more smoothly. At the same time, since the rotating head can be regarded as rigidly connected after being inserted into the slot, the angle adjustment mechanism can easily overcome the frictional resistance between the rubber ring and the spherical table during movement, and realize angle adjustment.

[0020] 5. By setting up a clamping assembly, the present invention allows the ring frame to be rotated by the operating handle, thereby guiding the movement of the central column using the arc groove, so that each clamping frame moves synchronously towards the center of the carrier, thereby clamping the hardware parts. After clamping, the ring frame is pressed by the pressure plate by turning the threaded knob to prevent the ring frame from retracting, thus improving the fixing effect. Attached Figure Description

Detailed Implementation

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1: A grinding device for manufacturing and processing hardware accessories, such as Figure 1-6 As shown, it includes: a central seat 1, a turntable 10 rotatably mounted on the central seat 1, a carrier mechanism distributed circumferentially around the rotation center of the turntable 10 on the turntable 10, the carrier mechanism including a ball seat 11, a spherical stage 41 movably mounted inside the ball seat 11, a central column in the middle of the spherical stage 41, a carrier 5 fixed on the top of the central column, and a clamping assembly for fixing the hardware accessories 9 on the carrier 5; An angle adjustment mechanism for adjusting the tilt angle of the spherical table 41 is provided below the turntable 10; a mounting base 7 is installed on the top of the center seat 1, and a grinding mechanism 8 is installed on the mounting base 7; the clamping center of the clamping assembly, the center of the carrier 5, and the position of the central column of the spherical table 41 are adapted to each other. The central seat 1 is equipped with a rotation drive mechanism for driving the turntable 10 to rotate. The rotation drive mechanism controls the rotation of the turntable 10, so that the carrier mechanism moves periodically between the grinding station and other stations.

[0026] To facilitate adjustment of the tilt angle of the carrier 5; such as Figures 3-5 As shown, the angle adjustment mechanism includes a lifting control component, a first angle adjustment component, and a second angle adjustment component. The first angle adjustment component is controlled by the lifting control component to switch between a working position and a standby position. The first angle adjustment component includes a first arc-shaped frame 22, on which a second arc-shaped frame 23 is slidably mounted. A first adjustment motor 24 is mounted at the bottom of the second arc-shaped frame 23. The first arc-shaped frame 22 is provided with first protruding teeth 26 distributed along a strictly arc-shaped path. A first gear 28 is mounted at the output end of the first adjustment motor 24, and the first gear 28 meshes with the first protruding teeth 26. The second angle adjustment component includes a slide block 30, which is slidably mounted on a second arc frame 23. A second adjustment motor 25 is mounted on the bottom of the slide block 30, and a second gear 29 is mounted on the output end of the second adjustment motor 25. A second tooth 27 is provided on the second arc frame 23 along an arc path, and the second gear 29 meshes with the second tooth 27. The movement path of the second arc frame 23 and the movement path of the slide block 30 are orthogonal in the top view, and in the working position, the movement center of the movement path of the second arc frame 23 and the movement center of the slide block 30 coincide with the center of the sphere of the spherical table 41. A connecting component is installed on the slide 30. The central column in the middle of the spherical stage 41 extends downward to the bottom of the spherical stage 41. When the carrier mechanism is in the grinding station, it operates based on the lifting control component. When the first angle adjustment component and the second angle adjustment component rise to the working position, the connecting component couples with the central column.

[0027] To facilitate control of the rotation of the carrier 5; such as Figure 4 , Figure 5 As shown, the connecting assembly includes a rotation control motor 32, which is mounted on the slide 30. A rotating head 31 is mounted on the output end of the rotation control motor 32. A slot adapted to the rotating head 31 is provided at the bottom end of the central column. Guide slopes are provided on the edge of the slot of the central column and the top of the rotating head 31. By setting up a carrier mechanism and an angle adjustment mechanism, the hardware parts 9 can be fixed on the carrier mechanism. The turntable 10 is used to transport the hardware parts 9 to the grinding station, where the grinding mechanism 8 is used for grinding. The grinding mechanism 8 can be a robotic arm with a grinder, or various lead screw modules, etc., to control the grinding and movement of the grinder. During the process, the angle adjustment mechanism can be used to control the movement of the ball table 41 within the ball seat 11 to change the posture of the hardware parts 9 to meet different grinding needs. Because the ball table 41 has a high degree of freedom of movement, it can better realize the grinding operation of the hardware parts 9 at different angles.

[0028] To facilitate control of the lifting frame 15; such as Figure 3 , Figure 4 As shown, the lifting control assembly includes a base frame 12, on which multiple uprights are fixed. A lifting frame 15 is fixed to the bottom of the first arc-shaped frame 22. The lifting frame 15 is slidably connected to the uprights of the base frame 12. A lifting control motor 18 is fixed on one of the uprights of the base frame 12. A lifting control screw 17 is installed at the output end of the lifting control motor 18. One end of the lifting control screw 17 is rotatably installed on the base frame 12. By setting up structures such as lifting control motor 18 and lifting control screw 17, the lifting control motor 18 can work to drive the lifting control screw 17 to rotate, thereby causing the lifting frame 15 to move up and down under the guidance of the upright frame.

[0029] To facilitate the stability of the carrier mechanism; such as Figure 3 As shown, a limiting bracket 14 is provided below the turntable 10. The limiting bracket 14 is concentrically arranged with one large and one small bracket. The limiting bracket 14 has an opening at the grinding station. A mounting plate 34 is fixed on the outer side of the bottom of the central column of the spherical table 41. A ball bearing 33 is movably provided on the mounting plate 34. When the turntable 10 rotates, the ball bearing 33 rolls on the limiting bracket 14. By setting the ball bearing 33 and the limiting bracket 14, the limiting bracket 14 can reliably support the carrier mechanism when the turntable 10 is conveying the carrier mechanism, thus avoiding structural tilting. The opening set in the limiting bracket 14 at the grinding station can provide space for the movement of the spherical table 41.

[0030] To ensure that the rotating head 31 is accurately inserted into the slot of the central column; as Figure 3As shown, a fixed frame 13 is fixed on the base frame 12. An arc-shaped plate 21 is slidably mounted on both the fixed frame 13 and the center seat 1. The end of the arc-shaped plate 21 has an arc-shaped structure that matches the limiting bracket 14. The arc-shaped plate 21 is connected to its mounting surface by a spring 20. The arc-shaped plate 21 extends into the opening of the limiting bracket 14 based on the support of the spring 20 and cooperates with the limiting bracket 14 to form a closed-loop structure. A crossbar 19 is fixed on the arc-shaped plate 21, and a lever 16 is fixed on the lifting frame 15. A wedge block is fixed on the top of the lever 16, and the crossbar 19 is located on the movement path of the wedge block. When the first angle adjustment assembly and the second angle adjustment assembly rise to the working position, the wedge block at the top of the lever 16 pushes the arc-shaped plate 21 to both sides. The top of the adjacent arc-shaped outer wall of the arc plate 21 is provided with a guide bevel; By setting up structures such as the arc-shaped plate 21 and the lever 16, the carrier assembly can be stably supported during transportation by using the limit bracket 14 and the arc-shaped plate 21, thus preventing structural tilting. At the same time, when grinding is required, the lifting frame 15 is raised, and the rotating head 31 is inserted into the slot of the central column. Simultaneously, the wedge-shaped block at the top of the lever 16 pushes the arc-shaped plate 21 to both sides, providing space for angle adjustment. After grinding, the angle adjustment mechanism controls the structure to return to center, the lifting mechanism controls the structure to reset, and the rotating head 31 separates from the slot of the central column. At the same time, the arc-shaped plate 21 resets based on the rebound force of the spring 20. Due to the setting of the guide bevel, the arc-shaped plate 21 can move smoothly to the bottom of the mounting plate 34 to provide support.

[0031] To facilitate maintaining the stability of the spherical table 41; such as Figure 6 As shown, a rubber ring 42 is fixed on the ball seat 11, and the rubber ring 42 is in contact with the spherical table 41; By setting the rubber ring 42, the spherical table 41 can maintain its posture stability as much as possible without being subjected to external force, so that the rotating head 31 can be inserted into the slot at the bottom of the central column more smoothly. At the same time, since the rotating head 31 can be regarded as a rigid connection after being inserted into the slot, the angle adjustment mechanism can easily overcome the frictional resistance between the rubber ring 42 and the spherical table 41 during movement, and realize angle adjustment.

[0032] To facilitate the fixing of hardware accessories 9; such as Figure 5 , Figure 6As shown, the clamping assembly includes a clamping frame 46. The top of the carrier 5 has circumferentially distributed strip grooves. The center line of the strip grooves and the central axis of the central column both intersect at the center of the carrier 5. The clamping frame 46 is slidably installed in the strip grooves. Preferably, there are three clamping frames 46. A central column 40 is fixed on the clamping frame 46. A ring frame 6 is rotatably installed on the carrier 5. The ring frame 6 has arc-shaped grooves 38 with the same number and position as the central columns 40, and each central column 40 extends into the corresponding arc-shaped groove 38. The distance between the arc-shaped grooves 38 and the center of the carrier 5 gradually decreases in a clockwise or counterclockwise direction. An operating handle 39 is fixed on the ring frame 6. A side bracket 35 is fixed on one side of the carrier 5. A threaded knob 36 is threadedly connected to the side bracket 35. A pressure plate 37 is fixed at the bottom of the threaded knob 36 and is located above the ring frame 6. By setting up the clamping components, the ring frame 6 can be rotated by the operating handle 39, thereby guiding the central column 40 to move using the arc groove 38, so that each clamping frame 46 moves synchronously towards the center of the carrier 5, thereby clamping the hardware accessories 9. After clamping, the ring frame 6 is pressed by the pressure plate 37 by turning the threaded knob 36 to prevent the ring frame 6 from retracting, thus improving the fixing effect.

[0033] To facilitate the rotation of the turntable 10; such as Figure 2 As shown, the rotation drive mechanism includes a turntable control motor 45, and a third convex tooth 43 is provided on the turntable 10 in a circular arrangement. A turntable control gear 44 is installed at the output end of the turntable control motor 45, and the turntable control gear 44 meshes with the third convex tooth 43.

[0034] Example 2: A grinding device for manufacturing and processing hardware accessories, such as Figure 1 , Figure 2 As shown, in order to facilitate the maintenance and upkeep of the spherical table 41, this embodiment makes the following improvements based on embodiment 1: a lubrication mechanism is provided on one side of the center seat 1. The lubrication mechanism includes a lubricating fluid supply device 2 and a mounting bracket 3. The output end of the lubricating fluid supply device 2 is connected to a nozzle 4 through a connecting pipe. The nozzle 4 is fixed on the mounting bracket 3, and the output end of the nozzle 4 extends to one side of the conveying path of the spherical table 41. A micro-groove is provided on the side of the rubber ring 42 near the spherical table 41. By setting a lubrication mechanism, lubricating fluid can be delivered to the nozzle 4 based on the lubricating fluid supply device 2 as needed, and sprayed onto the surface of the spherical stage 41 by the nozzle 4. During the process of the spherical stage 41 being controlled by the angle adjustment mechanism, the lubricating fluid can be better diffused to all parts of the spherical stage 41. The micro groove of the rubber ring 42 can prevent the lubricating fluid from being blocked in the area above the rubber ring 42. Applying lubricant helps to remove impurities that may accidentally enter the gap between the spherical table 41 and the ball seat 11 during the movement of the spherical table 41. During structural design, the coated spherical table 41 should still maintain a relatively reliable frictional force with the rubber ring 42 to prevent the spherical table 41 from moving without external force. Specifically, this can be achieved by changing the size, material, and surface texture of the rubber ring 42. Preferably, the rubber ring 42 is designed to be detachable for easy replacement as needed. Furthermore, since the slot of the central column and the top of the rotating head 31 are both provided with guide ramps, even in the event of slight structural misalignment, the rotating head 31 can still be smoothly inserted into the slot, improving fault tolerance.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
