Abstract
Description
Technical Field
[0001] This application relates to the field of headphone manufacturing and processing, and in particular to a limiting tooling for headphone production. Background Technology
[0002] Ordinary headphones typically consist of a speaker unit, a front shell, a back shell, and a headphone cable (one end of the cable connects to the speaker unit, and the other end is a plug). In-ear headphones also have a rubber sleeve. Most headphones are currently dual-ear headphones, meaning they have a left and a right earpiece, although some are single-ear headphones. Headphones are usually manufactured using specialized production lines, and the headphones need to be positioned during the production process.
[0003] Currently, headphone positioning devices typically use positioning feet to press down on the headphone during the positioning process to achieve positioning and facilitate headphone manufacturing. However, the pressing height of the positioning feet is fixed, which cannot adapt to different headphone sizes and has poor applicability, so it needs to be improved. Utility Model Content
[0004] To address the issue that positioning devices are unable to position headphones of different sizes and have poor applicability, this application provides a limiting fixture for headphone production.
[0005] The limiting tooling for headphone production provided in this application adopts the following technical solution:
[0006] A limiting fixture for headphone production includes a mounting plate, a limiting foot, and a positioning foot. The mounting plate is provided with a limiting plate, and the limiting foot is hinged to the limiting plate and can rotate in the vertical direction. The mounting plate is provided with a support base, and the support base is provided with a guide post. The guide post is vertically arranged, and a positioning plate is sleeved on the support post. The positioning plate can move vertically on the guide post, and the positioning foot is connected to the positioning plate.
[0007] By adopting the above technical solution, during use, the earphone is placed below the limiting foot and the positioning foot, and then the limiting foot and the positioning foot are pressed against the earphone. At this time, the limiting foot and the positioning foot apply a compressive force to the earphone, pressing it down to prevent displacement and thus positioning the earphone for subsequent processing. The limiting foot can rotate around the connection point between the limiting foot and the limiting plate, allowing the vertical height of the limiting foot and the positioning foot to be adjusted. This makes it suitable for pressing against earphones of different sizes and thicknesses, thus improving its applicability.
[0008] Optionally, the limiting plate is provided with a magnet, which is attracted to a magnetic block on the mounting plate.
[0009] By adopting the above technical solution, the limiting plate is placed on the mounting plate, so that the magnet is attracted to the magnetic block, thus realizing the installation of the limiting foot on the mounting plate. By applying force to move the limiting plate away from the mounting plate, the magnet is separated from the magnetic block, thus realizing the disassembly of the limiting plate, which facilitates the replacement of the limiting foot.
[0010] Optionally, an adjustment plate is hinged to the mounting plate, the adjustment plate being able to rotate in the vertical direction, and the adjustment plate being fixed to the limiting plate via a connecting plate.
[0011] By adopting the above technical solution, when placing the headphones, first rotate the adjustment plate so that the connecting plate drives the limiting plate to flip upward, that is, the limiting foot moves away from the mounting plate, making the space below the limiting foot larger, which makes it easier to place the headphones below the limiting foot. At the same time, lift the positioning plate so that the positioning plate moves on the guide post, which also makes the space below the positioning foot larger, thus making it easier to place the headphones in place.
[0012] Optionally, the limiting plate is provided with a limiting frame, the limiting foot is located below the limiting frame, the limiting frame is provided with a limiting hook and a fixing hook, the fixing hook is rotatably connected to the limiting frame, the middle part of the limiting hook is rotatably connected to the limiting frame, the limiting hook is connected to the limiting frame through a connecting spring, the connecting spring is used to drive the bottom end of the limiting hook to hook onto the mounting plate, and the top end of the limiting hook is provided with a limiting hole for the fixing hook to be inserted.
[0013] By adopting the above technical solution, rotating the fixed hook causes it to disengage from the arc-shaped limiting hole, thus freeing the limiting hook from restriction. Under the action of the connecting spring, the bottom end of the limiting hook hooks onto the mounting plate, meaning the limiting bracket cannot move upwards away from the mounting plate. Since the limiting bracket is connected to the limiting plate, the limiting plate and the adjusting plate cannot be flipped, ensuring that the limiting foot cannot rotate significantly. The gap between the limiting foot and the limiting bracket allows the limiting foot to rotate upwards at a small angle, achieving fine adjustment of the limiting foot height.
[0014] Optionally, the limiting frame is provided with a plurality of limiting springs, the top end of the limiting springs being fixed to the limiting frame, and the bottom end of the limiting springs abutting against the top wall of the limiting foot.
[0015] By adopting the above technical solution, the limiting spring applies downward pressure to the limiting foot, thereby enabling the limiting foot to press firmly against the lower earphone, increasing the stability of the limiting foot pressing against the earphone and improving the stability of the earphone positioning.
[0016] Optionally, a movable block is slidably connected to the support base. The movable block is connected to the support base via a push spring. The push spring is used to drive the movable block to move towards the positioning plate. The movable block is provided with a positioning block, which can abut against the top wall of the positioning plate.
[0017] By adopting the above technical solution, when placing the earphone, the moving block is moved away from the positioning plate, compressing the push spring and separating the moving block from the positioning plate. This allows the upper limit of the positioning plate to move up and down along the guide post, raising the positioning foot so that the earphone is placed below the positioning foot. When the positioning foot is placed on the earphone, the height of the positioning plate is below the moving block. The elastic force of the push spring pushes the moving block towards the positioning plate until the positioning block abuts against the top wall of the positioning plate, thus limiting the upward movement of the positioning plate and fixing the height of the positioning foot, increasing the stability of the positioning foot pressing against the earphone.
[0018] Optionally, the top of the positioning block is provided with a guide surface, and the end of the guide surface away from the moving block is inclined downward.
[0019] By adopting the above technical solution, once the positioning plate surpasses the height of the positioning block and reaches above it, the earphone can be placed below the positioning foot. The positioning foot then moves downwards, causing the positioning plate to move lower. When the positioning plate reaches the same height as the positioning block, it abuts against the guide surface. As the positioning plate continues to move downwards, the guide surface acts as a guide, allowing the positioning plate to slide relative to the guide surface. This causes the moving block to compress the push spring, moving horizontally away from the positioning plate until the positioning plate separates from the guide surface. Subsequently, when the positioning plate reaches below the positioning block, the push spring loses its compressive force and returns to its original deformation, shifting the positioning block horizontally onto the top wall of the positioning plate, thus limiting the upward movement of the positioning plate. During this process, the positioning plate can be moved directly downwards to pass over the positioning block without manual pressing, making the operation convenient.
[0020] Optionally, an adjustment groove is provided through the positioning plate, and a screw is fixed on the positioning hook. The screw is inserted into the adjustment groove and can move in the adjustment groove. A nut is sleeved on the screw and is threadedly connected to the screw. The nut can abut against the positioning plate to fix the positioning hook on the positioning plate.
[0021] By adopting the above technical solution, the nut is adjusted upwards to separate it from the positioning plate, allowing the screw to move within the adjustment groove and adjust the horizontal position of the positioning foot, thus adapting to headphones of different sizes. Once the positioning foot is in place, the nut is adjusted downwards until it presses against the positioning plate, thereby fixing the positioning foot to the positioning plate.
[0022] In summary, this application includes at least one of the following beneficial effects:
[0023] 1. In use, place the earphone below the limiting foot and positioning foot, then place the limiting foot and positioning foot against the earphone. At this time, the limiting foot and positioning foot apply pressure to the earphone, pressing it down to prevent displacement and positioning the earphone for subsequent processing. The limiting foot can rotate around the connection point between the limiting foot and the limiting plate, allowing the vertical height of the limiting foot and positioning foot to be adjusted, thus making it suitable for earphones of different sizes and thicknesses, improving its applicability.
[0024] 2. Adjust the nut upwards to separate it from the positioning plate, allowing the screw to move within the adjustment slot and adjust the horizontal position of the positioning foot to accommodate different sized headphones. Once the positioning foot is in place, adjust the nut downwards until it presses firmly against the positioning plate, thus fixing the positioning foot to the plate. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses a limiting tooling for headphone production. (Refer to...) Figure 1 and Figure 2The headphone production limiting fixture includes a mounting plate 10, a limiting foot 40, and a positioning foot 70. An adjusting plate 20 is hinged to the mounting plate 10, and a connecting plate 21 is bolted to the adjusting plate 20. The connecting plate 21 is bolted to a limiting plate 30, and a magnet 31 is fixed on the limiting plate 30. The magnet 31 attracts the magnetic block on the mounting plate 10, thus enabling the limiting plate 30 to be installed on the mounting plate 10. The limiting foot 40 is hinged to the limiting plate 30. Specifically, the adjusting plate 20 and the limiting foot 40 rotate in the same direction, both of which can rotate vertically towards or away from the mounting plate 10.
[0031] Reference Figure 1 and Figure 2 A support base 50 is bolted to the mounting plate 10. A guide post 51 is fixed to the support base 50. The guide post 51 is arranged vertically, and a positioning plate 60 is fitted onto the guide post 51. The positioning plate 60 can move vertically on the guide post 51. An adjustment groove 61 is formed through the positioning plate 60. A screw 71 is fixed to the positioning hook. The screw 71 is inserted into the adjustment groove 61 and can move within the adjustment groove 61, thereby changing the horizontal position of the positioning foot 70. A nut 711 is fitted onto the screw 71. The nut 711 is threadedly connected to the screw 71 and abuts against the positioning plate 60, thereby fixing the positioning hook onto the positioning plate 60.
[0032] In use, first rotate the adjusting plate 20 so that the connecting plate 21 drives the limiting plate 30 to flip upward, that is, the limiting foot 40 moves away from the mounting plate 10, making the space below the limiting foot 40 larger, which makes it easier to place the headphones below the limiting foot 40. At the same time, lift the positioning plate 60 so that the positioning plate 60 moves on the guide post 51, which also makes the space below the positioning foot 70 larger, thus making it easier to place the headphones in place.
[0033] Reference Figure 1 and Figure 2 After the earphone is placed below the limiting foot 40 and the positioning foot 70, the limiting foot 40 and the positioning foot 70 are then pressed against the earphone. At this time, the limiting foot 40 and the positioning foot 70 apply a squeezing force to the earphone, pressing it down to prevent displacement and thus positioning the earphone for subsequent processing. The limiting foot 40 can rotate around the connection point between the limiting foot 40 and the limiting plate 30, allowing the vertical height of the limiting foot 40 and the positioning foot 70 to be adjusted, making it suitable for earphones of different sizes and thicknesses, thus improving its applicability. The positioning foot 70 can move along the length of the adjustment groove 61 to adjust its horizontal position, making it suitable for earphones of different sizes.
[0034] Reference Figure 1 and Figure 2When the limiting foot 40 is pressed against the earphone, in order to prevent the limiting foot 40 from flipping upward, a limiting frame 80 is fixed on the limiting plate 30. The limiting foot 40 is located below the limiting frame 80. The limiting frame 80 is provided with a limiting hook 81 and a fixing hook 82. The fixing hook 82 is rotatably connected to the limiting frame 80.
[0035] The middle part of the limiting hook 81 is rotatably connected to the limiting frame 80. The limiting frame 80 is provided with a connecting spring 812. One end of the connecting spring 812 is fixed to the limiting frame 80, and the other end is fixed to the limiting hook 81. The connecting spring 812 is used to drive the bottom end of the limiting hook 81 to hook onto the mounting plate 10. The top end of the limiting hook 81 is provided with a limiting hole 811, and the fixing hook 82 can be inserted into the limiting hole 811.
[0036] In the initial state, the fixing hook 82 is inserted into the limiting hole 811. The side wall of the fixing hook 82 abuts against the inner wall of the limiting hole 811, which plays a limiting role, preventing the limiting hook 81 from rotating. This keeps the limiting hook 81 separated from the mounting plate 10, so that the limiting frame 80 can drive the limiting plate 30 and the limiting foot 40 to flip.
[0037] Reference Figure 1 and Figure 2 After the height of the limiting foot 40 is determined, rotate the fixing hook 82 so that the fixing hook 82 is pulled out of the limiting hole 811. At this time, under the action of the connecting spring 812, the bottom end of the limiting hook 81 hooks onto the mounting plate 10, that is, the limiting frame 80 cannot move upward away from the mounting plate 10. The limiting frame 80 is connected to the limiting plate 30, so that the limiting plate 30 and the adjusting plate 20 cannot be flipped, ensuring that the limiting foot 40 cannot rotate significantly. The gap between the limiting foot 40 and the limiting frame 80 allows the limiting foot 40 to rotate upward at a small angle, realizing the fine adjustment of the height of the limiting foot 40.
[0038] Reference Figure 1 and Figure 2 Several limiting springs 83 are installed on the limiting frame 80. The top end of the limiting spring 83 is fixed to the limiting frame 80, and the bottom end of the limiting spring 83 abuts against the top wall of the limiting foot 40. The limiting spring 83 applies downward pressure to the limiting foot 40, thereby enabling the limiting foot 40 to press firmly against the earphone below, increasing the stability of the limiting foot 40 pressing against the earphone and improving the stability of the earphone positioning.
[0039] Reference Figure 2 and Figure 3When the positioning foot 70 is pressed against the earphone, in order to prevent the positioning foot 70 from moving upward, a moving block 90 is provided on the support base 50. A push spring 91 is connected to the moving block 90. One end of the push spring 91 is fixed to the moving block 90 and the other end is fixed to the support base 50. The push spring 91 is used to drive the moving block 90 to move closer to the positioning plate 60. A positioning block 92 is integrally formed on the moving block 90. The positioning block 92 can abut against the top wall of the positioning plate 60.
[0040] When placing the headphones, the movable block 90 is moved away from the positioning plate 60, compressing the push spring 91 and separating the movable block 90 from the positioning plate 60. This allows the upper limit of the positioning plate 60 to move up and down along the guide post 51, raising the positioning foot 70 so that the headphones are placed below the positioning foot 70. When the positioning foot 70 is placed on the headphones, the height of the positioning plate 60 is below the movable block 90. The elastic force of the push spring 91 pushes the movable block 90 towards the positioning plate 60 until the positioning block 92 abuts against the top wall of the positioning plate 60, thus limiting the upward movement of the positioning plate 60 and fixing the height of the positioning foot 70, increasing the stability of the positioning foot 70 against the headphones.
[0041] Reference Figure 2 and Figure 3 The top of the positioning block 92 is provided with a guide surface 921, and the end of the guide surface 921 away from the moving block 90 is inclined downward. When the positioning plate 60 passes the height of the positioning block 92 and reaches above the positioning block 92, it facilitates the placement of the earphone below the positioning foot 70. Then, the positioning foot 70 moves down, causing the positioning plate 60 to move down. When the positioning plate 60 moves to the same height as the positioning block 92, the positioning plate 60 will abut against the guide surface 921. The positioning plate 60 continues to move down, and the guide surface 921 acts as a guide, causing the positioning plate 60 to slide relative to the guide surface 921. This causes the moving block 90 to compress the push spring 91 and move horizontally away from the positioning plate 60 until the positioning plate 60 separates from the guide surface 921. Subsequently, the positioning plate 60 reaches below the positioning block 92, the pushing spring 91 loses its compressive force and thus restores its deformation, moving the positioning block 92 to the top wall of the positioning plate 60, restricting the upward movement of the positioning plate 60. During this process, the positioning plate 60 can be moved down directly to pass through the positioning block 92 without manual pressing, making the operation convenient.
[0042] The implementation principle of the headphone production limiting fixture in this application embodiment is as follows: During use, the headphone is placed below the limiting foot 40 and the positioning foot 70. Then, the limiting foot 40 and the positioning foot 70 abut against the headphone. At this time, the limiting foot 40 and the positioning foot 70 apply a compressive force to the headphone, pressing it down to prevent displacement and thus positioning the headphone for subsequent processing. The limiting foot 40 can rotate about the connection point between the limiting foot 40 and the limiting plate 30, allowing the vertical height of the limiting foot 40 and the positioning foot 70 to be adjusted. This makes it suitable for abutting headphones of different sizes and thicknesses, improving its applicability.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
