Description

Technical Field

[0001] This utility model relates to the field of audio equipment manufacturing technology, specifically to a drilling device for audio equipment manufacturing. Background Technology

[0002] In the audio equipment manufacturing process, the drilling process for speaker mounting housings is a crucial step in ensuring the assembly precision of the audio equipment. However, traditional drilling equipment has many limitations in practical operation: Most devices can only meet the drilling requirements of a single position, making it difficult to adapt to the diverse drilling needs of different speaker housing models. The operation is cumbersome and inefficient when adjusting horizontally or vertically. At the same time, during the drilling process, due to the lack of effective limiting and guiding structures, the drilling mechanism is prone to deviation due to shaking, which affects the fit between the housing and the speaker and may even cause the product to be scrapped. The connection between traditional drill bits and drive mechanisms is complicated, and it takes a lot of time to change different types of drill bits, which reduces the continuity of production and makes it difficult to meet the efficiency requirements of mass production.

[0003] According to the description in the patent application published on the Internet, a drilling device for audio equipment production (authorization announcement number: CN119094969A) includes a "base plate, mounting bracket" and other components to perform drilling operations.

[0004] Regarding the above description, the applicant believes the following issues exist: This drilling device for audio equipment manufacturing uses a base plate and mounting bracket to perform drilling operations. When in use, this device uses a cutting blade to perform drilling operations, and the cutting blade is fixed on a blade holder. When the required drilling size is different, this device cannot perform drilling operations, and the cutting blade can only drill in a fixed position, which cannot adapt to the diverse drilling needs of different audio equipment housings. Therefore, this device needs to be improved. Utility Model Content

[0019] This utility model provides the following technical solution: Example 1

[0020] Please see Figure 1-6 This utility model provides a technical solution: a drilling device for audio production, including a processing table 1, a drilling mechanism 2 on the top of the processing table 1, and a fixing mechanism 3 on the top of the processing table 1; The drilling mechanism 2 includes a fixed frame 21, which is fixedly connected to the rear top of the processing table 1. A guide rod 22 is fixedly connected to the top inner side of the fixed frame 21. A first hydraulic cylinder 23 is fixedly connected to the right side of the fixed frame 21. A movable seat 24 is fixedly connected to the left side of the first hydraulic cylinder 23. The movable seat 24 is slidably connected to the periphery of the guide rod 22. A second hydraulic cylinder 25 is fixedly connected to the front top of the movable seat 24. A mounting base 27 is fixedly connected to the bottom of the second hydraulic cylinder 25. A limit rod 26 is fixedly connected to the top of the mounting base 27. A servo motor 28 is fixedly connected to the top inner side of the mounting base 27. A connecting shaft 29 is fixedly connected to the bottom of the servo motor 28. A drill bit 292 is inserted into the connecting shaft 29. The drill bit 292 is located on the top of the fixed mechanism 3. A fixed shaft 291 is inserted into the drill bit 292. A fixed sleeve 293 is threadedly connected to the left periphery of the fixed shaft 291.

[0021] The limiting rod 26 is slidably connected inside the movable seat 24. Two sets of guide rods 22 are provided and symmetrically distributed inside the movable seat 24, so as to ensure the balance of the mounting seat 27 when it moves through the limiting rod 26.

[0022] The fixed shaft 291 passes through the inside of the connecting shaft 29. The drill bit 292 and the connecting shaft 29 are respectively provided with fixing grooves, and the two fixing grooves correspond to each other. The fixed shaft 291 is inserted into the fixing groove, which facilitates the quick installation and fixing of the drill bit 292 and the connecting shaft 29 through the fixed shaft 291. Example 2

[0023] Please see Figure 1-6 Furthermore, based on Embodiment 1, the fixing mechanism 3 further includes a support frame 31, which is fixedly connected to the left side of the processing table 1. A third hydraulic cylinder 32 is fixedly connected to the left side of the support frame 31, and a clamping plate 34 is fixedly connected to the right side of the third hydraulic cylinder 32. A support rod 33 is fixedly connected to the left side of the clamping plate 34 and is slidably connected inside the support frame 31. A speaker housing 37 is provided on the right side of the clamping plate 34, and a support shaft 36 is fixedly connected to the bottom of the clamping plate 34. The support shaft 36 is located at the bottom of the speaker housing 37, and a support seat 35 is fixedly connected to the bottom of the clamping plate 34 and is slidably connected inside the processing table 1.

[0024] The right side of the clamping plate 34 and the inner side of the support shaft 36 are in contact with the left side and bottom of the speaker housing 37, respectively. The support shaft 36 is L-shaped, and rubber pads are provided on the right side of the clamping plate 34 and the inner side of the support shaft 36 to facilitate the fixing and support of the speaker housing 37 through the clamping plate 34 and the support shaft 36.

[0025] The top of the speaker housing 37 is in contact with the bottom of the drill bit 292. The support base 35 is I-shaped, which facilitates the stability of the clamping plate 34 when it moves.

[0026] The support frame 31, the third hydraulic cylinder 32, the support rod 33, the clamping plate 34, the support base 35 and the support shaft 36 are provided in two sets and are symmetrically distributed on the left and right sides of the speaker housing 37. This allows for the fixing of speaker housings 37 of different sizes by setting two sets.

[0027] In actual operation, when this device is used, and when drilling is required for the speaker housing during the audio production process, the speaker housing 37 is first positioned in the middle of the inner sides of the two sets of clamping plates 34 according to the size of the speaker housing 37. The clamping plates 34 are moved by the third hydraulic cylinder 32. When the clamping plates 34 move, the support rod 33 slides inside the support frame 31, and the support seat 35 slides inside the processing table 1. This guides and stabilizes the movement of the clamping plates 34, preventing them from shifting or shaking during the movement. When the right side of the clamping plates 34 and the inner side of the support shaft 36 contact the left side and bottom of the speaker housing 37, the operation of the third hydraulic cylinder 32 can be stopped, and the speaker housing 37 is in a stable state. Two sets of symmetrically distributed support frames 31, a third hydraulic cylinder 32, a support rod 33, a clamping plate 34, a support base 35, and a support shaft 36 are suitable for fixing speaker housings 37 of various sizes. The rubber pads on the right side of the clamping plate 34 and the inner side of the support shaft 36 can increase friction when clamping the speaker housing 37, preventing the speaker housing 37 from slipping during drilling, and also preventing the clamping plate 34 and the support shaft 36 from scratching or indenting the surface of the speaker housing 37, thus protecting the appearance quality of the speaker housing 37. Once the fixing is complete, select a drill bit 292 with a matching opening size. Different sizes of drill bits 292 only differ in the diameter of the opening at the bottom, while everything else is the same. Insert the drill bit 292 into the connecting shaft 29, and insert the fixing shaft 291 into the connecting shaft 29 and the drill bit 292. Thread the fixing sleeve 293 onto the outer periphery of the left end of the fixing shaft 291 to complete the installation of the drill bit 292. Depending on the drilling position, the first hydraulic cylinder 23 drives the movable seat 24 to slide around the guide rod 22, which can conveniently adjust the drilling position laterally to adapt to different drilling needs. At the same time, the second hydraulic cylinder 25 drives the mounting seat 27 to move up and down to adjust the height of the drill bit 292. When adjusting the height, the servo motor 28 drives the connecting shaft 29 and the drill bit 292 to work. When the drill bit 292 contacts the speaker housing 37, drilling can begin. When the mounting base 27 moves up and down, it will drive the limit rod 26 to slide inside the moving base 24, avoiding drilling deviation caused by shaking, and effectively improving the verticality and accuracy of drilling. When it is necessary to change to a different model of drill bit 292, simply unscrew the fixing sleeve 293 and pull out the fixing shaft 291 to quickly change the drill bit 292. After the change is completed, it is firmly fixed by the fixing shaft 291 and the fixing sleeve 293. The operation is simple and quick, reducing the time cost of changing the drill bit 292 and improving production efficiency. After processing a suitcase shell, the staff needs to clean the debris on the top of the processing table 1 and the equipment. At the same time, placing the collection device at the bottom of the processing table 1 can also collect some of the debris generated during processing. In this application, all the first hydraulic cylinders 23, the second hydraulic cylinders 25, the third hydraulic cylinders 32, and the servo motors 28 need to be connected to the same PLC controller to ensure coordinated and automated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail here.
