Description

Technical Field

[0001] The invention relates to the technical field of guitar production, and in particular to a polishing device for guitar production and a use method thereof. Background Art

[0002] Guitar is a string instrument, usually with six strings, which are plucked or struck to produce sound. Its main resonance box (i.e., the body) is usually made of wood, so after the body is manufactured, it is often necessary to polish the body in order to remove surface burrs and better oil or paint.

[0003] The traditional polishing method is to use a handheld grinder to polish the front, back and sides of the guitar, which wastes a lot of manpower. In addition, since the manual polishing is handheld, it is difficult to control the contact force between the grinder and the guitar body during the polishing process. The polished guitar surface is likely to have uneven polishing. Therefore, the manual polishing method has high requirements on the workers' skills and is difficult to carry out large-scale and standardized production.

[0004] In view of this, with the advancement of science and technology, some manufacturers have developed polishing devices for guitar polishing processes to replace the manual polishing and grinding process. These devices mostly use a clamping structure to clamp the body of the guitar on the device, and then start the drive structure to move the grinding wheel for grinding. This automated equipment solves the problems encountered in manual polishing. However, the defect of this equipment is that in practical applications, on the one hand, it can only polish one plane of the guitar at a time. After polishing, it is necessary to loosen the clamping structure and manually change the surface before continuing to polish. This cycle can be completed six times before it can be completely polished. This polishing method is inefficient and makes the process incomplete. In addition, the various surfaces of the guitar are not flat, especially the side of the guitar, which usually has a gourd-shaped curvature. In the existing technology, the polishing wheel does not make adaptive adjustments to the arc shape of the guitar body during the polishing operation. In other words, during the polishing process, the position of the polishing wheel is fixed, which means that the distance between it and the different curvature areas on the surface of the guitar is inconsistent. Therefore, in the area with a closer distance, the pressure applied by the polishing wheel is greater; while in the area with a farther distance, the pressure will be reduced. This will lead to uneven polishing effect on the same surface.

[0005] In view of this, it is necessary to improve the above defects.

[0006] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0045] Please refer to the instruction manual Figures 1 to 10The present invention discloses a polishing device for guitar production, which mainly includes two parallel vacuum adsorption devices 1, a bracket 2, a top surface polishing assembly 3, a lifting assembly 4, a side polishing assembly 5, a synchronization assembly 6, a rolling assembly 7 and a support assembly 8, wherein the vacuum adsorption device 1 is used to adsorb a guitar body or a guitar mold to fix the guitar body or the guitar mold, and the two vacuum adsorption devices 1 can be synchronously rotated 90 degrees; the bracket 2 is in an inverted concave shape, which is arranged above the vacuum adsorption device 1, and the bracket 2 is arranged to perform forward and backward translational movement by setting a driving component; the top surface polishing assembly 3 and the side surface polishing assembly 5 are arranged on the bracket 2, and the top surface polishing assembly 3 can grind and polish the top surface of the guitar, and is lifted and lowered by the lifting assembly 4; the side surface polishing assembly 5 is linked by the synchronization assembly 6 and the rolling assembly 7, and when in use, the rolling assembly 7 rolls and moves along the side edge of the guitar, driving the side polishing assembly 5 to grind the edge of the guitar body on the other side with the same displacement amplitude; finally, the support component 8 is used to support the overall operation of the device, and a cavity 9 for accommodating a device for driving the vacuum adsorption device 1 to rotate is arranged in the support component 8.

[0046] Through the above structure, the polishing device for guitar production described in the present invention can polish the four side surfaces and the top surface of the guitar in a total of three dimensions. Most of the time, the back of the guitar does not need to be polished. If necessary, the polishing requirement of the back can be met by turning the guitar over.

[0047] In order to further describe the above-mentioned components and structures, in a preferred embodiment of the present invention, the above-mentioned vacuum adsorption device 1 includes an internally hollow shell 10, the top surface of the shell 10 is opened, and a suction cup 11 is arranged in the opening. The top surface of the suction cup 11 is provided with a layer of silicone layer, and the silicone layer extends out of the opening, and can be tightly fitted with the bottom surface of the guitar body or the guitar mold. At the same time, a vacuum generator 12 is arranged at the bottom of the shell 10. The vacuum generator 12 is preferably a vacuum pump, which is connected to the inside of the suction cup 11 through a plurality of air pipes 13. When in use, the vacuum pump is started to extract the air in the suction cup 11 by vacuuming, so that the suction cup 11 and the bottom surface of the guitar body or the guitar mold are adsorbed, and finally the guitar body is fixed on the vacuum adsorption device 1, ensuring that it will not be displaced during the polishing process.

[0048] Therefore, after the side polishing assembly 5 has finished polishing one side of the guitar, the vacuum adsorption device 1 is driven to rotate 90 degrees so that the other side perpendicular to the previous side faces the side polishing assembly 5. Subsequently, the side polishing assembly 5 is started again to polish the side, and this cycle is repeated three times until all four sides of the guitar body are completely polished. This process is realized by the structure arranged at the bottom end of the vacuum adsorption device 1.

[0049] For details, please refer to the manual. Figure 5 The present invention is designed to have a connecting plate 14 fixedly connected to the bottom of the housing 10, and a rotating support plate 15 fixedly connected to the bottom of the connecting plate 14. The rotating support plate 15 is used as a dividing point, and the upper surface and the lower surface of the rotating support plate 15 are both located inside the supporting component 8, and the components below the rotating support plate 15 are all located inside the containing cavity 9. The rotating support plate 15 and the top surface of the supporting component 8 are movably connected, that is, they can rotate relative to the supporting component 8, and the bottoms of the two rotating support plates 15 are both fixedly connected to a rotating shaft 16, and the outer surface of the rotating shaft 16 is fixedly connected to a pulley 5 17, and the pulleys 5 17 on both sides are connected to each other by a belt 3 18. Therefore, when the pulley 5 17 on one side rotates, the belt 3 18 can drive the pulley 5 17 on the other side to rotate, and finally drive the vacuum adsorption device 1 thereon to rotate. In order to drive the pulley 5 17 to rotate, the present invention has a rotating seat 19 connected to the bearing below the rotating shaft 16 on one side, which is used to support the inner bottom wall of the containing cavity 9, as shown in the attached figure. Figure 5 As shown, the rotating seat 19 is fixed, and the rotating shaft 16 rotates with the pulley 5 17. At the same time, a groove wheel group 21 driven by the motor 4 20 is arranged below the rotating shaft 16 on the other side, as shown in the appendix of the specification. Figure 5 As shown, the groove wheel group 21 includes a notched turntable fixedly linked to the motor four 20, and a toggle rod is arranged on the notched turntable, and next to it, fixedly connected to the rotating shaft 16, is a groove wheel, and the groove wheel has four deep notches and four arc openings, and the arc diameter of the arc opening is equal to the diameter of the notched circular disk. Therefore, when the motor four 20 rotates to drive the toggle rod to rotate, the small toggle block on the toggle rod will penetrate into the deep notch on the groove wheel and toggle the groove wheel to rotate, and so on. The ratio of the groove wheel motion period to the residence period of the groove wheel group 21 is 1:3, that is, when the notched turntable rotates one circle, the toggle groove wheel rotates 90°, and then the vacuum adsorption device 1 thereon is accurately controlled to rotate 90° to achieve edge change polishing.

[0050] The rotation of the vacuum adsorption device 1 is to cooperate with the grinding of the side polishing component 5. The side polishing component 5 is linked to the hemming component 7 through the synchronization component 6. The hemming component 7 follows the side edge of the guitar body or the mold and then transmits it to the synchronization component 6, which controls the side polishing component 5 to move with the same amplitude, so that the side edges of the guitar body in different curve areas are polished with the same polishing pressure. For details, please refer to the attached manual. Figures 2-3In a preferred embodiment of the present invention, the side polishing assembly 5 includes a polishing wheel 36, which is fixedly connected to a plug shaft and rotatably connected to a wheel seat 37 through the plug shaft. At the same time, a pulley 38 is fixedly connected to one side of the plug shaft, and a pulley 39 is arranged on one side of the pulley 38. The pulley 39 and the pulley 38 are connected to each other by a belt 40. A motor 41 is fixedly connected to the pulley 39, and a motor box 42 is fixedly connected to the periphery of the motor 41. A belt box 43 is arranged on the periphery of the belt 40. Therefore, the pulley 39 is driven to rotate by the motor 41, and the pulley 38 is driven to rotate through the transmission of the belt 40, thereby realizing the rotation of the polishing wheel 36 and realizing friction polishing.

[0051] Next, on the other side, i.e., the side opposite to the polishing wheel 36, a roll edge assembly 7 is arranged thereon, and the roll edge assembly 7 includes a roller 44, which is arranged transversely and can roll on the side edge of the guitar body or the guitar mold, and a wheel seat 45 is arranged on the roller 44, and a sleeve rod 46 is fixedly connected to the side of the wheel seat 45 away from the roller 44, and a sleeve 47 is sleeved on the sleeve rod 46 and slides in the sleeve 47, and a spring 48 is sleeved on the outer periphery of the sleeve rod 46, and the two ends of the spring 48 are respectively fixedly connected to the sleeve 47 and the wheel seat 45, and the end of the sleeve rod 46 away from the wheel seat 45 is fixedly connected to a limiting block 49;

[0052] The synchronization component 6 includes a special-shaped connecting rod 50, which connects the motor box 42 and the limit block 49 together. The bottom end of the bracket 2 is fixedly connected with a support rod 51 and a support rod 52, respectively. The support rod 51 is located on the side close to the polishing wheel 36. The bottom end of the support rod 52 is fixedly connected to the sleeve 47. The connecting rod 50 passes through the rod body of the support rod 51 and the support rod 52 and slides therein. The wheel seat 2 37 is connected to the connecting rod 27 by providing a support portion 63.

[0053] Therefore, as the instructions Figures 2-3 , Fig. 9 As shown, in a preferred embodiment of the present invention, as the bracket 2 moves, the position of the roller 44 also changes. When it is not subjected to pressure, the spring 48 is in a relaxed state, so there is no deformation force to drive the roller 44 to move. At this time, the position of the roller 44 is recorded as the initial depth, and when the roller 44 moves to contact the side edge of the guitar body or the mold, it will roll along the edge surface. Of course, if it is to roll along the edge surface throughout the entire process, the initial depth of the roller 44 needs to be greater than or equal to the deepest depth of the side edge curved surface of the guitar body.

[0054] As roller 44 continues to move, its lateral position will also follow the changes in the side edge curve of the guitar body. When it is subjected to pressure, it will drive sleeve rod 46 to move. Sleeve rod 46 slides in sleeve 47 and squeezes spring 48 to deform it. At this time, the position of connecting rod 50 will also move, thereby driving the position of polishing wheel 36 to change. Since the displacement amplitude of polishing wheel 36 is equal to that of connecting rod 50, and the displacement amplitude of connecting rod 50 is equal to that of sleeve rod 46; the displacement amplitude of sleeve rod 46 is equal to that of roller 44, and the displacement amplitude of roller 44 is ultimately determined by the curvature of the side edge curve of the guitar body or the mold, therefore, this enables polishing wheel 36 to always move along the side edge curve of the guitar body to achieve the effect of polishing and grinding, and the polishing degree of the side edges of different curved surface areas in the front and back are consistent, so that uneven force will not occur.

[0055] Through the above components, the present invention can finally achieve the polishing of the four sides of the guitar body. In order to be able to polish the top surface of the guitar body, a top surface polishing assembly 3 is required. Please refer to the attached manual for details. Figure 4 and Fig.10 As shown in the figure, in a preferred embodiment of the present invention, the top surface polishing assembly 3 includes a motor box 3 28 fixedly connected to the connecting rod 27, a motor 3 29 is fixedly connected inside the motor box 3 28, a pulley 3 30 is fixedly connected to the output shaft of the motor 3 29, a bearing portion 31 is connected to the lower bearing of the extension portion 26, a pulley 4 32 is fixedly connected to the periphery of the bearing portion 31, the pulley 4 32 and the pulley 3 30 are connected by a belt 2 33, a belt box 2 34 is provided on the periphery of the belt 2 33, a polishing wheel 2 35 is fixedly connected to the lower part of the bearing portion 31, and is driven by the motor 3 29 to realize the driving of the polishing wheel 2 35.

[0056] However, since the polishing of the four sides of the guitar body requires the bracket 2 to drive the side polishing assembly 5 to move four cycles, then, since the top surface polishing assembly 3 is also connected to the bracket 2, if the top surface polishing assembly 3 is continuously in contact with the top surface of the guitar body, the polishing degree of the top surface of the guitar body will be four times that of the side. Therefore, in order to avoid this situation, a lifting assembly 4 is provided in a specific embodiment of the present invention, and the lifting assembly 4 includes a lifting plate 22, and both sides of the bottom of the lifting plate 22 are connected to the top surface of the bracket 2 by a lifting cylinder 2 3, a lifting hole 24 is provided on the bracket 2, a lifting rod 25 is fixedly connected to the middle of the bottom end of the lifting plate 22, the lifting rod 25 passes through the lifting hole 24, extends to the bottom of the bracket 2 and is respectively fixedly connected with a forward extension 26 and a lateral connecting rod 27. When the top surface polishing assembly 3 is needed, the lifting cylinder 23 is lowered to make the top surface polishing assembly 3 contact with the top surface of the guitar. When the top surface polishing assembly 3 is not needed, the lifting cylinder 23 is raised to prevent it from contacting the top surface of the guitar. The combination of the two can control the consistency of the polishing degree of the top surface and the side surface.

[0057] Finally, there are the supporting component 8 and the blowing component. The supporting component 8 includes a base 53. Screw grooves 54 are provided on both sides of the top of the base 53. The bottom of the bracket 2 extends into the screw groove 54 and is provided with a threaded hole 55. A screw 56 is rotatably connected in the screw groove 54. The screw 56 is threadedly connected to the bracket 2 through the threaded hole 55. A motor box 57 is provided in front of the base 53. A motor 58 is fixedly connected in the motor box 57. The output shaft of the motor 58 is fixedly connected to the screw 56. Therefore, when the motor 58 is powered on and started, its output shaft will drive the screw 56 to rotate. Under the influence of the threaded connection, the bracket 2 will follow the thread. The thread on the rod 56 moves to complete the above-mentioned polishing process. At the same time, the top of the screw groove 54 is covered with a flexible and deformable folding screen 59. The two ends of the folding screen 59 are respectively fixedly connected to the bracket 2 and the inner wall of the screw groove 54 to block the dust that is entangled during the polishing process; and the blowing component includes a rear seat 60, which is fixed to the rear part of the base 53. The rear seat 60 is provided with a plurality of evenly distributed fan openings 61, and a fan 62 is arranged in the fan opening 61. A detachable dust filter screen (not shown in the figure) is arranged at the front and rear parts of the fan opening 61 to prevent dust from entering the interior of the fan 62 of the fan buckle 61.

[0058] When in use, the fan 62 is started to blow away dust during the polishing process, thereby ensuring that the operating surface is clean and tidy.

[0059] Based on the above disclosed polishing device for guitar production, the operating method of the present invention is as follows:

[0060] S1, placing the guitar body on the vacuum adsorption device 1 located on one side close to the side polishing assembly 5 and the top polishing assembly 3, starting the vacuum adsorption device 1, and performing vacuum adsorption on the guitar body;

[0061] S2, placing the guitar model or another guitar body on another vacuum adsorption device 1, and adsorbing it in the same way as S1;
