Description

Technical Field

[0001] This application relates to the field of speaker basket manufacturing, and in particular to a polishing device for an audio speaker basket. Background Technology

[0002] As an integral part of the speaker, the speaker grille serves to support and secure various speaker components. During the manufacturing process of the speaker grille, its outer surface needs to be polished to achieve a smooth finish that meets requirements.

[0003] Existing methods for polishing speaker trays include manual and mechanical methods. While manual polishing yields good results, it is slow and costly. Mechanical polishing currently offers fully automatic and semi-automatic options. Fully automatic polishing mostly utilizes multi-axis robotic arms to grip and polish the speaker tray. However, multi-axis robotic arms are expensive to manufacture, and the programming and adjustment of their control are also significant ongoing costs, making it uneconomical for small and medium-sized machining enterprises.

[0004] Semi-automatic methods are commonly used by small and medium-sized machining enterprises. However, semi-automatic methods often require manual placement of the speaker frame into the grinding device and fixing it with screws or bolts to ensure that the speaker frame is no longer loose before the grinding process is carried out. This type of method is still relatively inefficient. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a grinding device for speaker baskets, which can shorten the time during the basket fixing process and improve efficiency.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A polishing device for a speaker basket includes a platform, a placement frame rotatably mounted on the platform, and a polishing assembly mounted on the platform. The placement frame includes a rotating rod that rotates relative to the platform, a placement rod located above the rotating rod, and a plurality of limiting members disposed between the rotating rod and the placement rod. The placement rod slides along the axial direction of the rotating rod, and the limiting members have limiting portions that clamp the frame rod of the speaker basket.

[0008] Preferably, the limiting member includes an upper limiting rod rotatably connected to the placement rod and a lower limiting rod rotatably connected to the rotating rod. The limiting part is located at the end of the upper limiting rod and away from the placement rod. The end of the lower limiting rod is hinged to the middle section of the upper limiting rod. An elastic member is provided between the placement rod and the rotating rod.

[0009] Preferably, the placement rod has a support platform for placing the basin stand.

[0010] Preferably, the rotating rod has an extension shaft that passes through the placement rod; a pressure ring is provided at the end of the extension shaft; and the lower surface of the pressure ring abuts against the basin stand.

[0011] Preferably, the pressure ring is slidably connected to the extension shaft.

[0012] Preferably, the lower pressure ring is threadedly connected to the extension shaft.

[0013] Preferably, the limiting part consists of two protrusions, with a groove formed between the two protrusions for accommodating the frame rod of the basin stand.

[0014] Preferably, the polishing assembly includes a polishing frame and a polisher disposed on the polishing frame, the polisher being connected to a power source via an electrical wire, and the polishing frame being fixed with multiple limiting buckles.

[0015] Preferably, the limiting buckle includes a fixed part that is fixedly connected to the grinding frame and a movable part that is rotatably connected to the fixed part, and a torsion spring is provided between the fixed part and the movable part.

[0016] Preferably, the equipment platform is further provided with a driving component, which is connected to the rotating rod in a transmission manner.

[0017] In summary, this utility model has the following beneficial technical effects:

[0018] As the workers place the basin stand onto the placement rack, the rack's weight drives the limiting mechanism, which then restricts the basin stand's frame. The basin stand then rotates relative to the placement rack. A rotating rod then slowly rotates the basin stand, allowing the grinding components to polish it. This method shortens the time required to fix and limit the basin stand, thus improving overall grinding efficiency. Attached Figure Description

These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0025] This application discloses a grinding device for a speaker basket.

[0026] Reference Figure 1 and Figure 2 A polishing device for a speaker basket includes a platform 1, a placement rack 2, and a polishing assembly 3. After the speaker basket 12 is placed on the placement rack 2 and secured, the polishing assembly 3 polishes the secured basket basket 12. Because the speaker basket 12 has a support rod 13, the placement rack 2 limits the movement of the support rod 13 while supporting the speaker basket 12. This allows the placement rack 2 to rotate, thus enabling the speaker basket 12 to rotate as well.

[0027] Reference Figure 2 and Figure 3 The placement rack 2 includes a rotating rod 21, a placement rod 22, and a limiting member 23. The rotating rod 21 is rotatably mounted on the equipment platform 1. The equipment platform 1 is also provided with a driving member 11, which is connected to the rotating rod 21 and can drive the rotating rod 21 to rotate, thereby causing the placement rack 2 to rotate. The driving member 11 is a motor.

[0028] The placement rod 22 is located directly above the rotating rod 21, and the rotating rod 21 has an extension shaft 211 that passes through the placement rod 22;

[0029] The placement rod 22 is allowed to slide along the axial direction of the extension shaft 211. This allows the placement rod 22 to move closer to or further away from the rotating rod 21. An elastic element 24, which is a spring, is provided between the placement rod 22 and the rotating rod 21.

[0030] Before the basin holder 12 is placed on the placement rod 22, the spring pushes the placement rod 22 away from the rotating rod 21, at which point the limiting member 23 is not engaged. The placement rod 22 has a support platform 221 for placing the basin holder 12. After the basin holder 12 is passed through the extension shaft 211 and placed on the support platform 221 on the placement rod 22, the weight of the basin holder 12 presses the placement rod 22 downward, and the placement rod 22 drives the limiting member 23, enabling the limiting member 23 to clamp the frame rod 13 of the basin holder 12.

[0031] The limiting member 23 has multiple components, including an upper limiting rod 232 and a lower limiting rod 233. The upper limiting rod 232 is longer than the lower limiting rod 233. The upper end of the upper limiting rod 232 is rotatably connected to the lower end of the placement rod 22. The lower end of the upper limiting rod 232, that is, the end away from the placement rod 22, is the limiting part 231, which can clamp the frame rod 13 of the basin stand 12. Specifically, the limiting part 231 consists of two protrusions, and a groove for accommodating the frame rod 13 of the basin stand 12 is formed between the two protrusions.

[0032] The lower end of the lower limit rod 233 is rotatably connected to the upper part of the placement rod 22, and the upper end of the lower limit rod 233 is hinged to the middle section of the upper limit rod 232. As the basin holder 12 moves downwards pressing against the placement rod 22, the placement rod 22 pushes the upper end of the upper limit rod 232 downwards, causing the lower end of the upper limit rod 232 to gradually tilt upwards. During this tilting process, the groove can engage with the frame rod 13. This allows the limiting member 23 to hold the basin holder 12 in place, preventing the basin holder 12 from rotating relative to the placement frame 2.

[0033] The extension shaft 211 passes through one end of the placement rod 22 and is provided with a pressure ring 25. The pressure ring 25 mainly serves as a counterweight. After the basin stand 12 is placed on the support platform 221, the lower surface of the pressure ring 25 abuts against the upper part of the basin stand 12. Using the weight of the pressure ring 25 and the basin stand 12, the limiting part 231 of the limiting member 23 is raised to limit the frame rod 13 of the basin stand 12.

[0034] In this application, the pressure ring 25 is slidably connected to the extension shaft 211. The pressure ring 25 achieves downward pressure limitation on the basin frame 12 by gravity. In other embodiments, the pressure ring 25 can also be threadedly connected to the extension shaft 211, and the downward pressure limitation is achieved by tightening.

[0035] The polishing assembly 3 includes a polishing frame 33, on which a polisher 31 is placed. The polisher 31 is a device used for polishing the basin stand 12, which is existing technology and will not be described in detail. The polisher 31 is connected to a power source via a power cord, and the polishing frame 33 is fixed with multiple limiting buckles 32. The power cord can be suspended on the polishing frame 33 through the limiting buckles 32, so that the power cord will not interfere with the work when the operator operates the polisher 31 to polish the basin stand 12.

[0036] The limit buckle 32 includes a fixed part 321 and a movable part 322. The fixed part 321 is fixedly connected to the grinding frame 33, and the movable part 322 is rotatably connected to the fixed part 321. The fixed part 321, the movable part 322 and the grinding frame 33 form a closed space, which is convenient for hanging the wire. A torsion spring is provided between the fixed part 321 and the movable part 322. The torsion spring is not shown in the figure. The torsion spring is mainly used for the reset of the movable part 322.

[0037] The implementation principle of this embodiment is as follows: When the basin stand 12 needs to be polished, simply place the basin stand 12 on the placement rod 22, and then the pressure ring 25 is fitted onto the extension shaft 211 to continue pressing down. As the placement rod 22 moves downward, the limiting part 231 of the limiting member 23 tilts upward to limit the frame rod 13 of the basin stand 12. Then, the worker can pick up the polisher 31 to polish the basin stand 12. The rotating rod 21 can rotate under the action of the motor, making it convenient for the worker to polish the outer circumference of the basin stand 12.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the above specific embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
