The following embodiments are used to illustrate the present invention.
[0020] Example 1: like Figures 1 to 11As shown, a polishing device for producing picture frame-type audio equipment includes a mounting housing 1. A lower worktable 11 is mounted on the mounting housing 1, and an upper worktable 111 is mounted on the lower worktable 11. Side plates 112 are arranged around the lower and upper worktables 111. Four support frames 113 are also arranged above the upper worktable 111, and a top plate 114 is arranged above the four support frames 113. A slot is also formed on the upper worktable 111, and a circular turntable 12 is arranged at the slot. An annular groove 3 is formed above the circular turntable 12, and a circular groove 31 is formed inside the annular groove 3. A circular rotating platform 311 is rotatably mounted, and a clamping assembly 321 is mounted above the circular rotating platform 311. A picture frame-type speaker body 4 is placed on the clamping assembly 321, which is used to position the placed picture frame-type speaker body 4. A driving assembly is mounted on the lower worktable 11. The driving assembly is used to control the rotation of the outer polishing assembly 241 and the inner polishing assembly 243, which are used to polish the positioned picture frame-type speaker body 4. The driving assembly is also used to control the rotation of the circular turntable 12 and to assist the rotation of the circular rotating platform 311. The side plate 112, top plate 114, cover plate 13, lower circular protective shell 14, and upper circular protective shell 141 of the housing 1 form a closed space to ensure operational safety and prevent debris from flying and damaging the equipment. The drive components are efficiently linked, which can drive the circular turntable 12 to revolve and the circular rotating table 311 to rotate intermittently. They can also control the outer polishing component 241 and the inner polishing component 243 to operate synchronously. The two are closely attached to the inner and outer sides of the picture frame-type speaker body 4, and the combination of revolution and rotation can achieve multi-directional polishing.
[0021] like Figures 5 to 6 As shown, in a specific embodiment, a lower circular protective shell 14 is provided above the lower worktable 11, an upper circular protective shell 141 is provided at the bottom of the circular turntable 12, and a circular mounting plate 22 is also provided on the lower worktable 11. In this configuration, the installation positions of the upper circular protective shell 141 and the lower worktable 11, as well as their installation relationship, are determined.
[0022] like Figures 1 to 11 As shown, furthermore, the bottom of the top plate 114 is provided with four mounting brackets 131 arranged in a circular pattern, and the bottom of the four mounting brackets 131 is provided with cover plates 13, which fit into the annular grooves 3. In this configuration, the installation position of the cover plates 13 and the relationship between the cover plates 13 and the annular grooves 3 are determined.
[0023] like Figures 1 to 11As shown, furthermore, a mounting bearing 122 is provided at the bottom of the top plate 114, and a rotating rod 121 is provided at the bottom of the mounting bearing 122. The end of the rotating rod 121 away from the mounting bearing 122 is positioned above the circular turntable 12. In this configuration, the installation position of the rotating rod 121 is determined.
[0024] Example 2: The difference between the above embodiments and this embodiment is that: Figures 6 to 11 As shown, a picture frame type speaker production polishing device is provided. The driving component includes a servo motor 2, which is mounted on a lower worktable 11. A rotating rod 21 is provided at the output end of the servo motor 2. The end of the rotating rod 21 away from the servo motor 2 is located at the bottom of a circular turntable 12. A connecting rod 211 is provided on the rotating rod 21.
[0025] like Figures 5 to 11 As shown in the specific embodiment, the inner wall of the annular mounting plate 22 is provided with a plurality of semi-circular sliding grooves 221 and U-shaped sliding grooves 222 arranged in a circular pattern. Each semi-circular sliding groove 221 is connected to a pair of U-shaped sliding grooves 222, and each semi-circular sliding groove 221 and U-shaped sliding groove 222 is interconnected and slidably provided with a sliding block 223. In this configuration...
[0026] like Figures 1 to 11 As shown, further, a mounting rod 23 is provided at one end of the sliding block 223 near the drive assembly. A movable groove 231 is formed on one side wall of the mounting rod 23 near the drive assembly. A movable slider 232 is slidably disposed within the cavity of the movable groove 231. A connecting rod 211 is connected to the end of the movable slider 232 away from the movable groove 231. A support plate 233 is provided above the mounting rod 23. In this configuration, the position of the mounting rod 23 and the installation position of the support plate 233 are determined.
[0027] like Figures 1 to 11 As shown, furthermore, an outer placement frame 234 and an inner placement frame 235 are respectively provided at both ends of the upper part of the tray 233. An outer protective frame 24 and an inner protective frame 242 are respectively provided above the outer placement frame 234 and the inner placement frame 235. An outer polishing component 241 and an inner polishing component 243 are provided on opposite side walls of the inner cavities of the outer protective frame 24 and the inner protective frame 242. In this configuration, the installation positions of the outer polishing component 241 and the inner polishing component 243 are determined.
[0028] Example 3: The difference between the above embodiments and this embodiment is that: Figures 1 to 11As shown, a polishing device for producing picture frame-type audio equipment includes a fixed plate 32 positioned above a circular rotating table 311, and a clamping assembly 321 mounted on the fixed plate 32. The installation positions of the fixed plate 32 and the clamping assembly 321 are defined in this configuration.
[0029] like Figures 1 to 11 As shown in the specific embodiment, the outer ring of the circular rotating platform 311 is provided with a toothed ring 33, and a plurality of circumferentially distributed drive gears 331 are provided on one side wall of the toothed ring 33. Each drive gear 331 meshes with the toothed ring 33, and each toothed ring 33 is disposed on the cover plate 13. In this configuration, when the circular rotating platform 311 rotates to a specific position, the polishing assembly is in a downward moving state under the guidance of the U-shaped slide groove 222. At this time, the toothed ring 33 meshes with the plurality of circumferentially distributed drive gears 331 disposed on the cover plate 13. The drive gears 331 drive the circular rotating platform 311 to rotate by meshing with the toothed ring 33, achieving a 90-degree turn.
[0030] The implementation principle of the picture frame type speaker production polishing device in this embodiment is as follows: The operator first places the frame-type speaker body 4 to be polished on the clamping assembly 321 above the circular rotating table 311. The clamping assembly 321 uses a preset positioning structure (existing technology) to accurately fix the workpiece, which can not only effectively prevent the workpiece from shifting during the polishing process, but also ensure that the center of the frame-type speaker body 4 is completely aligned with the central axis of the circular rotating table 311 and the circular turntable 12, laying the foundation for subsequent uniform polishing. Meanwhile, because the cover plate 13 at the bottom of the top plate 114 fits into the annular groove 3 on the circular turntable 12, together with the protective functions of the lower circular protective shell 14 and the upper circular protective shell 141, a closed polishing space is formed, which not only ensures operational safety but also prevents polishing debris from splashing and entering the equipment, causing damage. At the same time, the rotating rod 121 connected to the bottom of the top plate 114 via the mounting bearing 122 provides auxiliary support for the circular turntable 12, improving the stability of the circular turntable 12 during rotation and preventing deviation due to high-speed rotation. After the workpiece is positioned, the operator starts the servo motor 2 on the lower worktable 11, and the drive component officially enters the working state. The rotating rod 21 at the output end of the servo motor 2 starts to rotate. On the one hand, it directly drives the circular turntable 12 connected to the top to rotate synchronously, so that the workpiece placed on the circular turntable 311 moves in a circle with the circular turntable 12. On the other hand, the connecting rod 211 on the rotating rod 21 is connected to the movable slider 232 on the mounting rod 23. When the rotating rod 21 rotates, it will drive the mounting rod 23 to move to one side through the movable slider 232. The sliding block 223 on the other side of the mounting rod 23 is embedded in the semi-circular slide groove 221 and the U-shaped slide groove 222 of the circular mounting plate 22. Under the traction of the connecting rod 211, the sliding block 223 moves radially along the semi-circular slide groove 221 and switches up and down along the U-shaped slide groove 222, thus forming a circular reciprocating motion. Since the mounting rod 23 and the connecting rod 211 are connected by the sliding groove 231 and the sliding slider 232, the sliding slider 232 can only slide within the sliding groove 231, so that the mounting rod 23 can be raised and lowered smoothly when subjected to vertical force. This ultimately drives the support plate 233 and the outer polishing component 241 and the inner polishing component 243 above it to move synchronously, ensuring that the outer polishing component 241 is always close to the outer side of the picture frame type speaker body 4, and the inner polishing component 243 is tightly fitted to the inner side, providing a guarantee for precise polishing. At the same time, the outer protective frame 24 and the inner protective frame 242 respectively fix and protect the two sets of polishing components, preventing the components from shaking or being damaged during the polishing process. While the polishing components remain in contact with the workpiece, the staff controls the outer polishing component 241 and the inner polishing component 243 to start rotating, and simultaneously polish the inner and outer sides of the picture frame speaker body 4; at the same time, the rotation of the circular turntable 12 will drive the circular turntable 311 above to make a circular motion, and the toothed ring 33 on the outer ring of the circular turntable 311 will also rotate synchronously. When the circular rotating platform 311 rotates to a specific position, the polishing assembly moves downward under the guidance of the U-shaped slide 222. At this time, the toothed ring 33 meshes with the multiple circumferentially distributed drive gears 331 provided on the cover plate 13. The drive gears 331 drive the circular rotating platform 311 to rotate by meshing with the toothed ring 33, thus achieving a 90-degree turn. This turning action causes the unpolished side of the frame-type speaker body 4 to rotate to the working area of the polishing component. After the turning is completed, the polishing component continues to move along the slide under the drive of the drive component to polish the new side. This process is repeated continuously. By combining the revolution of the circular turntable 12 with the intermittent rotation of the circular rotating table 311, and with the continuous movement of the polishing components, the entire frame-type speaker body 4 is polished without any dead angles, ensuring that the surface of the workpiece is polished evenly and with the required precision. Throughout the entire process, each component, through precise structural design and transmission coordination, ensures both polishing efficiency and polishing quality, effectively meeting the polishing process requirements in the production of frame-type speakers.
