[0002] In the loudspeaker manufacturing industry, the drilling process is crucial to product quality and performance. Traditional loudspeaker drilling methods have many drawbacks, hindering production efficiency and product quality improvement.

[0003] In the past, manual drilling was the primary method, which was labor-intensive, slow, and subject to subjective factors, resulting in poor consistency in drilling position, depth, and diameter. This easily led to imbalances in the speaker's vibration system, electrical performance problems such as noise, and a high defect rate. Some manufacturers used general-purpose drilling equipment, but due to the diverse shapes, sizes, and special structures of speakers, general-purpose equipment struggled to accurately position and stably clamp them. Furthermore, it was impossible to quickly change the clamping device according to different drilling requirements, impacting production efficiency and increasing production costs.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Combination Figures 1 to 6The drilling device shown includes a worktable 1, a clamping device 2 for clamping and fixing a speaker 7 on the worktable 1, a fixing frame 3 on one side of the worktable 1, a translation device 4 on the fixing frame 3, a lifting device 5 on the translation device 4, and a drill bit 6 on the lifting device 5.

[0028] The clamping device 2 includes a rotating disk 201, which is embedded in the worktable 1. This installation method ensures the stability of the rotating disk 201 without hindering its flexible rotation. The rotating disk 201 is provided with a first clamping member 202, which provides initial positioning support for the speaker 7. Both ends of the rotating disk 201 are provided with cylinders 203. The output end of the cylinder 203 is connected to a connecting block 204. The two sets of connecting blocks 204 are connected to a second clamping member 205. When the cylinder 203 works, the distance between the second clamping member 205 and the first clamping member 202 can be precisely adjusted according to the size of the speaker 7, thereby firmly clamping speakers of different specifications. A first motor 206 is provided at the bottom of the worktable 1. The output end of the first motor 206 is connected to the rotating disk 201. The first motor 206 drives the rotating disk 201 to rotate. When it is necessary to adjust the angle of the speaker 7 to drill holes in different positions, this can be easily achieved by controlling the first motor 206, which greatly improves the flexibility of drilling.

[0029] The upper surface of the rotating disk 201 is provided with two sets of first fixing plates 207 and two sets of positioning blocks 208. The first fixing plates 207 are used to fix the cylinder 203, providing a stable installation position for the cylinder 203 and ensuring that the cylinder 203 will not be displaced during operation, thereby ensuring the stability and accuracy of the movement of the second clamping member 205. The positioning blocks 208 are used to position the first clamping member 202, achieving precise positioning. Installation and disassembly are very convenient. When it is necessary to replace different types of first clamping members 202 to adapt to special specifications of speakers, the operation can be completed quickly, improving the versatility of the equipment and the flexibility of production. This structural design makes the various components of the clamping device 2 tightly connected and accurately positioned, ensuring the stability and efficiency of the entire clamping process, reducing production failures caused by loose components or inaccurate positioning, and improving production efficiency and product quality.

[0030] The first clamping member 202 has an annular groove 209 with a sloping bottom. A cleaning port 210 is located at the bottom of the annular groove 209, and a cover plate 211 is provided on the cleaning port 210. When drilling, the generated debris will fall down the slope to the cleaning port 210. When cleaning is required, the cover plate 211 can be opened to easily remove the debris. The first clamping member 202 has a first connecting block 212 at both ends of its bottom. The first connecting block 212 has notches 213 on both sides and an oblong hole 214 in the middle. The notches 213 are matched and engaged with the positioning block 208, realizing the precise positioning of the first clamping member 202 on the rotating disk 201. The oblong hole 214 provides a certain degree of flexibility for installation and adjustment, making it convenient to fine-tune the position of the first clamping member 202 according to actual needs. This structural design takes into account multiple needs of fixing, cleaning and installation adjustment, making the first clamping member 202 more functional in the speaker production process and improving the applicability and reliability of the entire drilling device.

[0031] The second clamping member 205 has several equidistant clearance holes 215, which are located directly above the annular groove 209. The clearance holes 215 are designed to ensure that the drill bit 6 is not obstructed by the second clamping member 205 during the drilling process. The second clamping member 205 has a second connecting plate 216 at both ends. The second connecting plate 216 has two sets of through holes 217 for connecting with the connecting block 204. This connection method enables the second clamping member 205 to effectively clamp the speaker 7, and also ensures the smooth progress of the drilling operation, thereby improving the applicability and working efficiency of the entire drilling device.

[0032] The upper surface of the fixed frame 3 is provided with a second fixed plate 301 at both ends, and a rectangular hole 302 is opened in the middle position; the translation device 4 includes a first lead screw 401 rotatably connected between the second fixed plates 301, wherein a second motor 402 is provided on the outside of one of the second fixed plates 301, the output end of the second motor 402 is connected to the first lead screw 401, the first lead screw 401 is connected to a movable frame 403 through a ball nut, the lower surface of the fixed frame 3 is provided with a slide rail 404, the upper surface of the movable frame 403 is provided with a slide table 405, and the slide rail 404 and the slide table 405 are slidably connected.

[0033] The lifting device 5 includes two sets of guide rods 501 and a second lead screw 502. The second lead screw 502 is rotatably connected between the movable frame 403. A third motor 503 is mounted on the movable frame 403, and the output end of the third motor 503 is connected to the second lead screw 502. A lifting plate 504 is mounted on the guide rods 501 and the second lead screw 502. The lifting plate 504 is connected to the second lead screw 502 by a ball nut, and the lifting plate 504 is connected to the guide rods 501 by a linear bearing. When the second lead screw 502 rotates, the lifting plate 504 moves up and down along the lead screw direction. The two sets of guide rods 501 are for the movement of the lifting plate 504. The movement provides stable guidance, and the linear bearing reduces friction during the lifting process, making the lifting smoother and more stable. The lifting plate 504 is equipped with a drill bit 6, which performs the drilling operation on the speaker 7 as the lifting plate 504 moves up and down. This structural design of the lifting device 5 can precisely control the lifting height of the drill bit 6 to ensure that the drilling depth meets the requirements, while ensuring the stability and accuracy of the drilling process. Working in conjunction with the translation device 4, it can meet the drilling needs of different positions and depths of the speaker 7, greatly improving the functionality and applicability of the drilling device and meeting the diverse drilling process requirements in the speaker production process.
