Description

Technical Field

[0001] This application relates to the field of guitar processing equipment technology, and in particular to a positioning and assembly device for guitar processing. Background Technology

[0002] The guitar is a plucked string instrument, typically with six strings, and similar in shape to a violin. A guitar generally consists of three main parts: the headstock, the body, and the soundbox. The soundbox is the main body of the guitar, often called the "soundbox" or "body." It mainly comprises the top, back, and sides, and is the crucial part for the guitar's sound production. The top has components such as the soundhole, bridge, nut, strings, and pickguard. During the manufacturing process of the guitar's soundbox, a positioning assembly device is usually used to position the sides into their approximate shape before the top and back are joined, fixed, and glued together.

[0003] While the positioning and assembly devices for guitar manufacturing in related technologies can meet the basic requirements for clamping and positioning the side panels of the guitar body, at least the following shortcomings have been found in actual operation: Typically, the side panels are clamped and fixed only from the outer wall of the body. Since the shape formed by the side panels is hollow, a certain amount of tension cannot be applied from the inner wall of the side panels during clamping and positioning. This easily leads to uneven stress on the side panels, causing deformation and cracking, affecting the accuracy of subsequent processing steps such as splicing and gluing, and ultimately reducing the quality of guitar manufacturing.

[0004] Therefore, we propose a positioning and assembly device for guitar manufacturing to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a positioning and assembly device for guitar body processing, which effectively improves the accuracy and stability of the overall positioning of the guitar body side plates through the synergistic effect of clamping and supporting the side plates. It prevents displacement during side plate processing and avoids deformation or breakage due to uneven force on the side plates.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a positioning assembly device for guitar processing, comprising a guitar processing table and positioning component one and positioning component two disposed on the guitar processing table. Positioning component one is used to clamp and position the side plate of the guitar body, and positioning component two is used to support and position the side plate of the guitar body. Positioning component one includes a backing plate and a pad fixedly mounted on the top of the guitar processing table. An electric telescopic rod is fixedly mounted on the top of the pad, and a clamping plate is fixedly mounted on the output shaft end of the electric telescopic rod.

[0007] By adopting the above technical solution, the position of the clamping plate can be precisely controlled by the electric telescopic rod. By using the cooperation between the abutment plate and the clamping plate, it is possible to stably and accurately clamp and position the guitar body from the outer side wall.

[0008] A further feature of this application is that protective pads are fixedly installed on the sides of the abutment plate and the clamping plate that are close to each other.

[0009] By adopting the above technical solution, the protective pad not only prevents the side plate from being pinched, but also further enhances the stability of the clamping, avoids the side plate displacement caused by uneven local pressure, and ensures the positional accuracy of the piano body side plate when clamped.

[0010] A further provision of this application is that the top surface of the guitar processing table and the bottom surface of the clamping plate are both smooth planes, and the bottom of the clamping plate slides in contact with the top of the guitar processing table.

[0011] By adopting the above technical solution, it can be ensured that the clamping plate slides smoothly on the guitar processing table.

[0012] A further configuration of this application is as follows: the second positioning component includes a crossbeam located between the abutment plate and the clamping plate. Two mounting cavities are formed within the crossbeam, and a piston plate is provided in each of the two mounting cavities. The piston plate slides and seals against the inner wall of the mounting cavity. A horizontal shaft is fixedly installed on the side of the two piston plates that is far apart from each other. The ends of the two horizontal shafts that are far apart from each other extend to the outside of the corresponding mounting cavities. A tensioning head is fixedly installed on the end of the two horizontal shafts that is far apart from each other. A return spring is fixedly installed on the side of the two piston plates that is close to each other. The ends of the two return springs that are close to each other are fixedly connected to the inner wall of the corresponding mounting cavity. A U-shaped tube located between the two piston plates is fixedly installed on the top of the crossbeam. Both ends of the U-shaped tube extend to the corresponding mounting cavities. A pipe connector is fixedly connected to the U-shaped tube. An air pump is fixedly installed at the bottom of the guitar processing table. An air supply hose is fixedly connected to the exhaust end of the air pump. One end of the air supply hose is fixedly connected to one end of the pipe connector.

[0013] By adopting the above technical solution, air is supplied to the U-shaped tube by an air pump, which gradually increases the air pressure in the installation cavity. This pushes the piston plate to drive the horizontal shaft and the tensioning head to move, allowing for tensioning and positioning operations from the inner wall of the instrument body side plate. This ensures that the tensioning force is evenly distributed on the side plate, working in conjunction with the clamping and positioning to greatly improve the overall positioning accuracy of the instrument body side plate. This prevents displacement during side plate processing and avoids deformation or cracking due to uneven force on the side plate, which is beneficial for the accurate execution of subsequent processing steps such as splicing and bonding.

[0014] A further feature of this application is that: through holes are provided on the inner walls of the two mounting cavities on the sides that are far apart from each other, and the two horizontal axes pass through the corresponding through holes at their ends that are far apart from each other.

[0015] By adopting the above technical solution, it is possible to ensure smooth horizontal linear sliding of the horizontal axis.

[0016] A further feature of this application is that a sealing ring is fixedly installed on the inner wall of the through hole, and the horizontal shaft slides and seals with the through hole through the sealing ring.

[0017] By adopting the above technical solution, the sealing ring is used to seal the gap between the horizontal shaft and the through hole, preventing debris from entering the mounting cavity during processing.

[0018] A further feature of this application is that two electromagnetic check valves are fixedly installed on the U-shaped tube, and the pipe joint is located between the two electromagnetic check valves.

[0019] By adopting the above technical solution, the flow of gas can be easily controlled by two electromagnetic check valves, and the extension position of the two tensioning heads can be quickly realized. This allows for easy adjustment of the tensioning state as needed during processing, thereby improving the stability of the side plate positioning.

[0020] A further feature of this application is that two symmetrically arranged venting pipes are fixedly connected to the U-shaped tube, and an electromagnetic venting valve is fixedly installed on each of the two venting pipes.

[0021] By adopting the above technical solution, the gas pressure release can be easily controlled by the setting of the vent pipe and electromagnetic vent valve. Under the elastic force of the return spring, the tension head can be quickly retracted and returned to its original position, making it convenient to release the tension and positioning of the instrument body side plate after processing.

[0022] A further feature of this application is that the top of the guitar processing table is provided with a clearance hole, through which one end of the air supply hose passes.

[0023] By adopting the above technical solution and setting the avoidance hole, interference with the arrangement and normal use of the gas transmission hose can be avoided.

[0024] A further feature of this application is that a support frame is fixedly installed on the top of the guitar processing table, and a crossbeam is fixedly fitted onto the support frame.

[0025] By adopting the above technical solution, the support frame plays a stable fixing role for the crossbeam, making the positioning component two structurally stable during operation and not prone to shaking or displacement.

[0026] This application includes at least one of the following beneficial technical effects:

[0027] 1. This application utilizes positioning component one to clamp and position the side panel of the instrument body from the outer side wall.

[0028] 2. This application utilizes positioning component two to tighten and position the instrument body side panel from the inner side wall.

[0029] 3. By utilizing the combined use of positioning component one and positioning component two, namely the synergistic effect of clamping and supporting the side plate of the guitar body, this application effectively improves the accuracy and stability of the overall positioning of the side plate of the guitar body. During the processing of the side plate, there will be no displacement, and the side plate will not deform or crack due to uneven stress. This is conducive to the accurate execution of subsequent processing steps such as splicing and gluing, thereby improving the quality and craftsmanship of guitar making.

[0030] 4. This application utilizes the venting pipe and electromagnetic venting valve to facilitate the control of gas pressure release. Under the elastic force of the return spring, the tensioning head can be quickly retracted and returned to its original position, making it convenient to release the tensioning and positioning of the instrument body side plate after processing.

[0036] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a positioning and assembly device for guitar body processing, including a guitar processing table 1 and positioning component one and positioning component two disposed on the guitar processing table 1. Positioning component one is used to clamp and position the side plate of the guitar body, and positioning component two is used to support and position the side plate of the guitar body.

[0038] Positioning component one includes a backing plate 2 and a pad 3 fixedly mounted on the top of the guitar processing table 1. An electric telescopic rod 4 is fixedly mounted on the top of the pad 3, and a clamping plate 5 is fixedly mounted on the output shaft end of the electric telescopic rod 4. By utilizing the cooperation between the backing plate 2 and the clamping plate 5, the position of the clamping plate 5 is precisely controlled by the electric telescopic rod 4, enabling stable and accurate clamping and positioning from the outer wall of the guitar body side plate. Positioning component two includes a crossbeam 7 located between the backing plate 2 and the clamping plate 5. Two mounting cavities 8 are formed within the crossbeam 7, and each mounting cavity 8 contains a piston plate 9. The piston plate 9 slides and seals against the inner wall of the mounting cavity 8. A horizontal shaft 10 is fixedly mounted on the opposite side of each piston plate 9, with the opposite ends of the two horizontal shafts 10 extending out of their respective mounting cavities 8. A tensioning head 11 is fixedly mounted on the opposite end of each horizontal shaft 10, and a return spring 12 is fixedly mounted on the opposite side of each piston plate 9, with the opposite ends of the two return springs 12 respectively... A U-shaped tube 13 is fixedly connected to the inner wall of the corresponding mounting cavity 8. The top of the crossbeam 7 is fixedly installed between the two piston plates 9. The two ends of the U-shaped tube 13 extend into the corresponding mounting cavity 8. A pipe connector 14 is fixedly connected to the U-shaped tube 13. An air pump 15 is fixedly installed at the bottom of the guitar processing table 1. An air supply hose 16 is fixedly connected to the exhaust end of the air pump 15. One end of the air supply hose 16 is fixedly connected to one end of the pipe connector 14. The air pump 15 supplies air to the U-shaped tube 13, which pushes the piston plate 9 to drive the horizontal shaft 10 and the tensioning head 11 to move. The tensioning and positioning operation can be performed from the inner side wall of the guitar body. Its unique structural design makes the tensioning force evenly distributed on the side plate. In conjunction with the clamping and positioning, it greatly improves the overall positioning accuracy of the guitar body side plate. It prevents displacement during the processing of the side plate and prevents deformation and cracking due to uneven force on the side plate. It is conducive to the accurate execution of subsequent processing procedures such as splicing and gluing, thereby improving the quality and craftsmanship of guitar making.

[0039] In this embodiment, protective pads 6 are fixedly installed on the sides of the abutment plate 2 and the clamping plate 5 that are close to each other. The protective pads 6 not only prevent the side plates from being pinched, but also further enhance the stability of the clamping, avoid the side plates from shifting due to uneven local pressure, and ensure the positional accuracy of the guitar body side plates when clamped. The top surface of the guitar processing table 1 and the bottom surface of the clamping plate 5 are both smooth planes. The bottom of the clamping plate 5 slides in contact with the top of the guitar processing table 1, which allows the clamping plate 5 to slide smoothly on the guitar processing table 1.

[0040] In this embodiment, through holes are provided on the inner walls of the two mounting cavities 8 on the side away from each other, and the two horizontal shafts 10 are respectively passed through the corresponding through holes at the ends away from each other, so that the horizontal shafts 10 can slide smoothly in a horizontal straight line.

[0041] In this embodiment, a sealing ring is fixedly installed on the inner wall of the through hole. The horizontal shaft 10 slides and seals with the through hole through the sealing ring, which can seal the gap between the horizontal shaft 10 and the through hole and prevent debris from entering the mounting cavity 8 during processing.

[0042] In this embodiment, two electromagnetic check valves 17 are fixedly installed on the U-shaped tube 13, and the pipe joint 14 is located between the two electromagnetic check valves 17. The two electromagnetic check valves 17 on the U-shaped tube 13 facilitate the control of the gas flow direction and can quickly realize the extension position of the two tensioning heads. It is convenient to adjust the tensioning state as needed during the processing and improve the stability of the side plate positioning. Two symmetrically arranged venting pipes 18 are fixedly connected to the U-shaped tube 13. Electromagnetic venting valves 19 are fixedly installed on both venting pipes 18. The arrangement of venting pipes 18 and electromagnetic venting valves 19 facilitates the control of gas pressure release. Under the elastic force of the return spring 12, the tensioning heads can be quickly retracted and returned to their original position, which is convenient for releasing the positioning of the instrument body side plate after processing.

[0043] In this embodiment, the top of the guitar processing table 1 is provided with a clearance hole, through which the air supply hose 16 passes. The clearance hole ensures that the air supply hose 16 is arranged in a neat and orderly manner, avoiding interference and ensuring the normal operation of the entire device.

[0044] In this embodiment, a support frame 20 is fixedly installed on the top of the guitar processing table 1, and the crossbeam 7 is fixedly fitted on the support frame 20. The support frame 20 plays a stable fixing role on the crossbeam 7, so that the positioning component 2 is structurally stable during operation and is not prone to shaking or displacement, thus ensuring the reliability and stability of positioning.

[0045] In this embodiment, it should be noted that a controller is installed on the guitar processing table 1. The controller is equipped with multiple control buttons. The electric telescopic rod 4, air pump 15, electromagnetic one-way valve 17, electromagnetic venting valve 19 and the controller are electrically connected via guides. The multiple control buttons can be used to control the energization and operation of the electric telescopic rod 4, air pump 15, electromagnetic one-way valve 17 and electromagnetic venting valve 19 respectively. The wiring connection method and control method are mature technologies in this field, so they will not be described in detail here.

[0046] With the above structure, the working principle of the guitar processing positioning and assembly device provided in this application is as follows:

[0047] When clamping and positioning the side plate of the guitar body, first place the pre-processed side plate on the guitar processing table 1 between the back plate 2 and the clamping plate 5, so that one side of the outer wall of the side plate abuts against the protective pad 6 on the back plate 2, and the crossbeam 7 and the two tensioning heads 11 are located in the space enclosed by the side plate. Start the electric telescopic rod 4 to extend and run. The output shaft of the electric telescopic rod 4 drives the clamping plate 5 to slide linearly to the left. As the clamping plate 5 moves, when the protective pad 6 on the clamping plate 5 abuts against the other side of the outer wall of the side plate, stop the electric telescopic rod 4. This completes the clamping of the guitar body side plate placed between the back plate 2 and the clamping plate 5, and realizes the preliminary clamping and positioning operation of the side plate.

[0048] Then, start the air pump 15 and open the two solenoid one-way valves 17. The air pump 15 delivers gas through the exhaust end to the pipe joint 14 via the air supply hose 16, and then into the U-shaped tube 13. After entering the U-shaped tube 13, the gas flows into the two mounting chambers 8 respectively. The air pressure in the two mounting chambers 8 gradually increases. The gas pressure can be used to push the two piston plates 9 to move away from each other. The movement of the piston plates 9 drives the horizontal shaft 10 and the tensioning head 11 to move horizontally in a straight line. When the two tensioning heads 11 are in tight contact with the inner wall of the guitar body side plate, stop the air pump 15 and close the two solenoid one-way valves 17. At this time, the two tensioning heads 11 apply a certain tensioning force to the side plate. With the cooperation of the abutment plate 2 and the clamping plate 5, the side plate can be kept in a stable position, realizing the secondary tensioning and positioning operation of the side plate. Then the side plate can be spliced, glued and other processing.

[0049] After the side panel is processed, when it needs to be removed, the electromagnetic vent valve 19 is opened at the same time. The gas in the two mounting chambers 8 is discharged through the vent pipe 18. At this time, the air pressure in the two mounting chambers 8 returns to normal. The two return springs 12, which were previously stretched and stored elastic potential energy, release their elastic potential energy after the gas pressure disappears. This causes the two piston plates 9 to move towards each other, thereby causing the horizontal shaft 10 and the tensioning head 11 to retract and return to their initial state, thus releasing the tensioning and positioning of the side panel of the instrument body. Then, the electric telescopic rod 4 is controlled to retract and reset, which controls the clamping plate 5 and the protective pad 6 on it to move away from the side panel, thus releasing the clamping and positioning of the side panel, and the side panel can be removed.
