[0001] The invention relates to the technical field of sound production, and in particular to a drilling device for sound production. Background Art

[0002] With the progress of society, people's lives are more colorful, and the requirements for singing and dancing performances and venues are getting higher and higher. The sound system is constantly improving and perfecting with people's needs, from meeting the needs of live sound reinforcement for concerts with tens of thousands of people to meeting the needs of playing musical instruments at home. Sound is a very important device in the sound system. Sound is generally composed of a speaker unit and a cabinet. The speaker unit is the sound-generating component, and the cabinet plays the role of correcting the sound. In the production of sound, it is necessary to drill holes in the outer shell of the sound. Most construction workers use drilling devices to drill holes in the outer shell of the sound.

[0003] In the prior art, when punching holes in the shell of a wooden speaker, since the bottom of the shell is often hollow, the downward pressure of the punching device can easily cause the shell to be concave near the punching point, which may damage the structural integrity of the speaker shell and cause errors in the diameter of the hole. At the same time, a large amount of debris and dust will be generated during the punching process, and it is difficult to fully collect these debris and dust in the prior art devices. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned shortcomings in the prior art and to propose a drilling device for sound production.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0012] Preferably, symmetrically arranged cutting knives are fixedly mounted on both ends of the knife holder, with the blades of the cutting knives facing downwards.

[0013] Preferably, the length of the positioning frame is consistent with the width between the front and rear inner walls of the sound shell.

[0014] Preferably, a support rod is fixedly mounted on the inner top wall of the positioning frame, and the lower end of the support rod is fixedly connected to the bottom plate.

[0015] Preferably, the upper end surface of the support frame is configured to be circular or polygonal, and the radius of the inscribed circle of the circle or polygon is larger than the radius of the hole to be drilled.

[0016] Preferably, an adsorption rubber ring is glued to the upper surface of the support frame, and the adsorption rubber ring is made of rubber material.

[0017] Preferably, the sliding portion includes a slide groove opened at the upper end of the bottom plate, an electrically controlled slider is slidably connected inside the slide groove, a dust storage box is fixedly mounted on the upper end of the electrically controlled slider, and a lock is mounted on the dust storage box.

[0018] Preferably, the dust suction part includes a vacuum cleaner fixedly mounted on the upper end of the dust storage box, the working end of the vacuum cleaner faces one side of the support frame and is connected to a dust suction pipe, and the output end of the vacuum cleaner is connected to an exhaust pipe, and the end of the exhaust pipe away from the vacuum cleaner is connected to the interior of the dust storage box.

[0019] Preferably, a restraining steel layer is fixedly mounted on a surface of one side of the dust storage box close to the supporting frame, and a shock-absorbing rubber is glued to the inner side of the restraining steel layer.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. In the present application, a positioning frame is provided, which fits the inside of the speaker shell just right, which not only plays a positioning role, but also gives a certain supporting force to the speaker shell to prevent the speaker shell from deforming during the punching process; and the positioning frame can also absorb the vibration generated during the punching process, which can not only reduce noise but also make the punching more precise.

[0024] 4. In the present application, by providing the shock-absorbing rubber and the constrained steel layer, when the shock-absorbing rubber is fitted to the side of the speaker shell, the shock-absorbing rubber can firstly damp the vibration generated by the speaker shell. Since the shearing effect of the constrained steel layer is stronger than the shearing effect of the shock-absorbing rubber, the vibration bending generated by the constrained steel layer will be smaller than that of the shock-absorbing rubber, thereby further improving the shock-absorbing effect and the accuracy of drilling.

[0025] In summary, the device provides support below the drilling, collects debris generated during the drilling process, reduces vibration during drilling, and greatly improves the drilling accuracy and hole-forming effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figures 1 to 3 as well as Figure 5 A drilling device for audio production includes a bottom plate 1, a mounting frame 3 is fixedly installed on the left side of the upper end of the bottom plate 1, a hydraulic device 4 is fixedly installed on the upper end of the mounting frame 3 by welding or bolts, the output end of the hydraulic device 4 is fixedly connected to a rotating motor 5 after penetrating the upper side of the mounting frame 3, a knife holder 6 is fixedly installed on the output end of the rotating motor 5, and symmetrically arranged cutting knives 7 are fixedly installed at both ends of the knife holder 6, and the blades of the cutting knives 7 face downward. When the hydraulic device 4 is running, it can drive the rotating motor 5 and the knife holder 6 to move up and down, and when the rotating motor 5 is started, it can drive the two groups of cutting knives 7 to revolve, thereby achieving drilling of the surface of the audio shell 14.

[0036] Reference Figure 4 A positioning frame 15 is fixedly installed on the right side of the upper end of the base plate 1. The positioning frame 15 and the mounting frame 3 are located on the same axis, and the inner top wall of the positioning frame 15 and the upper surface of the base plate 1 are further strengthened and fixed by a support rod 16. In the subsequent processing process, one end of the audio shell 14 can be sleeved on the outside of the positioning frame 15. It should be noted that the length of the positioning frame 15 needs to be consistent with the width between the inner walls of the front and rear sides of the audio shell 14, so that the two can be just stuck together, making it difficult for the audio shell 14 to shake or move during the subsequent processing.

[0037] Reference Figure 4 as well as Figure 6 to Figure 7A connecting rod 19 fixedly mounted on the upper surface of the bottom plate 1 is provided between the mounting frame 3 and the positioning frame 15. A support frame 18 is fixedly mounted on the upper end of the connecting rod 19. The support frame 18 is located directly below the tool holder 6. The upper surface of the support frame 18 can be set to be circular or polygonal, but it should be noted that the radius of the inscribed circle of the circle or polygon needs to be larger than the radius of the hole to be drilled. On the one hand, it can facilitate drilling of the sound shell 14. On the other hand, the waste generated during the drilling process can fall into the inside of the support frame 18, which is convenient for collecting the waste generated during the drilling process. In addition, an adsorption rubber ring 17 is glued to the upper surface of the support frame 18. The adsorption rubber ring 17 is made of rubber material. On the one hand, it can reduce the vibration generated during the processing of the sound shell 14. On the other hand, it can avoid the debris from falling outside the support frame 18 as much as possible.

[0038] Both the front and rear sides of the support frame 18 are provided with a slide 2 opened at the upper end of the bottom plate 1. The two groups of slides 2 are staggered, and the two groups of slides 2 are slidably connected with an electric control slider 13. The upper end of the electric control slider 13 is fixedly installed with a dust storage box 8. The dust storage box 8 is installed with a lock buckle 9. By pressing the lock buckle 9, the dust storage box 8 can be locked or unlocked, so as to facilitate the control of the movement of the dust storage box 8. The upper end surface of the dust storage box 8 is fixedly installed with a dust collector 10 by welding or bolting. The working end of the dust collector 10 faces one side of the support frame 18 and is connected with a dust suction pipe 11, and the output end of the dust collector 10 is connected with the inside of the dust storage box 8 through the discharge pipe 12. When the vacuum cleaner 10 is running, it can suck away some of the debris generated during the drilling process and transfer it to the dust storage box 8, and due to the staggered setting of the two groups of vacuum cleaners 10 and the dust suction pipe 11, the debris and powder generated during the drilling process can be more fully sucked.

[0039] A restraining steel layer 21 is fixedly installed on the surface of one side of the dust storage box 8 close to the support frame 18, and a shock-absorbing rubber 20 is glued to the inner side of the restraining steel layer 21. When the shock-absorbing rubber 20 is in contact with the side of the sound shell 14, the shock-absorbing rubber 20 can first damp the vibration generated by the sound shell 14. Since the shearing effect of the restraining steel layer 21 is stronger than the shearing effect of the shock-absorbing rubber 20, the vibration bending generated by it will be smaller than the shock-absorbing rubber 20, which further improves the shock-absorbing effect and improves the accuracy of drilling.

[0040] The specific working principle of the present invention is as follows: the back of the sound shell 14 is facing upwards and turned upside down on the positioning frame 15. The positioning frame 15 just fits the inside of the sound shell 14, which not only plays a positioning role, but also gives the sound shell 14 a certain supporting force to prevent the sound shell 14 from deforming during the punching process; and the positioning frame 15 can also absorb the vibration generated during the punching, which can not only reduce noise but also make the punching more precise. The support rod 16 gives the positioning frame 15 a firm fixation.

[0041] While putting down the sound shell 14, the adsorption rubber ring 17 above the support frame 18 also fits tightly to the inner surface of the sound shell 14. The frame of the support frame 18 is relatively wide, and the position is just below the punching position. The wider frame provides better support to prevent the sound shell 14 from being greatly deformed when the cutting knife 7 is pressed down for cutting, thereby affecting the cutting effect. The middle of the support frame 18 is hollow, and the diameter is slightly larger than the diameter of the drilling position, so that the cut circular plate and the debris generated below the cutting can fall into the inside of the support frame 18, reducing the interference and obstruction of the debris during the punching process and improving the punching quality. The adsorption rubber ring 17 at the bottom not only plays an auxiliary fixing role, but also ensures that the debris will not fall outside the support frame 18.

[0042] Start the electric control slider 13 to slide in the slide groove 2, so that the two dust storage boxes 8 move forward at the same time. The surface of the dust storage box 8 is provided with a constraining steel layer 21, and a shock-absorbing rubber 20 is fixed in front of the constraining steel layer 21. The positions of the two dust storage boxes 8 are not in the same straight line, which can provide more force-bearing area and improve the fixing effect. After the shock-absorbing rubber 20 is fixed tightly against the side of the sound shell 14, press the lock buckle 9 to lock the dust storage box 8 so that it will not move. The shock-absorbing rubber 20 serves as the first layer to absorb vibration. The shearing effect of the constraining steel layer 21 tightly attached to the back is stronger than that of the shock-absorbing rubber 20, and the vibration bending generated will be smaller than that of the shock-absorbing rubber 20, which further improves the shock absorption effect. Improve the accuracy of drilling.

[0043] After being fixed, the hydraulic device 4 drives the tool holder 6 to descend, starts the rotating motor 5, and drills a hole on the back of the sound shell 14. A large amount of debris will be generated during the drilling process. Since the dust storage box 8 is misaligned, the dust suction pipe 11 on the vacuum cleaner 10 is also misaligned with each other, and is located at the upper and lower ends of the cutting circle respectively. This has the following advantages. First: staggering the two vacuum cleaners 10 can increase the coverage area of ​​the vacuum cleaner 10, so as to better absorb and collect the chips and dust generated in the cutting process; second: at both ends, vacuuming is performed along the direction of rotation of the rotating motor 5, and the centrifugal force of the debris can better absorb the debris generated in the drilling process.

[0044] After the drilling is completed, the debris at the bottom and the cut circular plate will fall into the support frame 18 below for easy collection. Since the sound shell 14 is fixed, the surface of the sound shell 14 can also be polished at this time. After the processing is completed, the lock 9 is opened, the dust storage box 8 is retreated, and the hydraulic device 4 is lifted up, and the processed sound shell 14 can be taken out.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
