Description

Technical Field

[0001] This utility model belongs to the field of musical instrument processing technology, and in particular relates to a device for polishing the edges of guitar frets. Background Technology

[0002] Guitar frets are horizontal metal strips inlaid on the guitar fretboard. Their core function is to divide the frets and determine the pitch. They are one of the key components for the guitar's sound production. They are mostly made of nickel-silver alloy, stainless steel, or pure copper, and are characterized by high hardness and wear resistance. They can withstand the pressure of the strings and the friction of pressing the strings for a long time. They are usually long strips with a semi-circular or circular cross-section, inlaid in the fret grooves of the fretboard, with a slightly raised top that contacts the strings to form a vibration node.

[0003] Chinese patent CN219075203U discloses a novel guitar polishing device, including a sliding block. A locking groove is provided on the lower side of the sliding block, and a screw hole is provided on one side of the locking groove. An adjusting screw is screwed into the screw hole, and the adjusting screw is fixed to a moving plate. The surface of the moving plate is engaged with the edge of the guitar. A polishing structure is rotatably connected to one end of the sliding block. An adjusting structure is provided on the sliding block, and the adjusting structure passes through the sliding block and engages with a recessed hole on the polishing structure. The surface of the polishing structure is in contact with the frets on the guitar. The polishing block is engaged in a groove on the polishing plate. This design allows for replacement of the polishing block after damage. The positioning holes on the polishing plate are arranged in a ring, allowing adjustment of the angle between the polishing block and the sliding block to achieve different tilt angles for polishing the frets.

[0004] As shown above, the device can grind the filaments into different tilt angles by adjusting the angle between the grinding block and the sliding block, and the grinding block can be replaced after it is damaged. The positioning holes on the grinding plate are arranged in a ring. However, the device is too large and inconvenient to carry, which reduces its applicability. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a device for polishing the edges of guitar frets, which solves the above-mentioned existing problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a device for polishing the edges of guitar frets, including a slide rail, a polishing mechanism provided on the inner wall of the slide rail for polishing the edges of guitar frets, and a driving component provided on the top of the outer wall of the slide rail for driving the device to perform polishing. The grinding mechanism includes a support frame fixed to the outer wall of the slide rail. A sliding block is slidably connected to the inner wall of the slide rail. A grinding plate is fixedly connected to the bottom of the sliding block. A moving plate is fixedly connected to the end of the sliding block away from the grinding plate. The drive assembly includes a rotating shaft one fixed to the top of the moving plate. A connecting rod one is rotatably connected to the end of the rotating shaft one away from the moving plate. A rotating shaft two is fixedly connected to the top of the connecting rod one.

[0007] Preferably, the end of the rotating shaft away from the connecting rod is rotatably connected to the connecting rod, the top of the connecting rod is fixedly connected to the rotating shaft, the top of the rotating shaft is fixedly connected to the handle, the outer surface of the handle is rotatably connected to the inner wall of the support frame, and the bottom of the moving plate is fixedly connected to the top of the slide rail.

[0008] Preferably, the outer wall of the slide rail is provided with a clamping mechanism for fixing the device. The clamping mechanism includes a clamping frame fixed to the outer wall of the slide rail, and two connecting blocks are fixedly connected to the outer wall of the slide rail.

[0009] Preferably, a fixing frame is fixedly connected to the outer wall of the connecting block, and there are two fixing frames. A fixing block is fixedly connected to one side of the two fixing frames that are close to each other, and a lead screw is rotatably connected to the inner wall of the fixing block.

[0010] Preferably, a threaded block is threadedly connected to the outer surface of the lead screw, a clamping plate is fixedly connected to the bottom of the threaded block, an auxiliary block is fixedly connected to the top of the clamping plate, an auxiliary rod is slidably connected to the inner wall of the auxiliary block, and the outer wall of the auxiliary rod is fixedly connected to the outer wall of the connecting block.

[0011] Preferably, the end of the auxiliary rod away from the connecting block is fixedly connected to the outer wall of the fixed block, a turntable is fixedly connected to the outer wall of the lead screw, a limiting plate is fixedly connected to the outer wall of the fixed block, an insert rod is slidably connected to the inner wall of the turntable, and the outer wall of the insert rod penetrates the outer wall of the turntable and extends into the interior of the limiting plate.

[0012] This utility model has the following beneficial effects: 1. This device for polishing the edges of guitar frets works by rotating a handle to drive a rotating shaft. When the shaft rotates, connecting rod two rotates simultaneously. At this time, the rotating shaft two drives connecting rod one, which is fixed at its bottom, to rotate. When connecting rod one rotates, the rotating shaft one rotates, causing the moving plate to move, which in turn moves the sliding block and the polishing plate fixed at the bottom of the sliding block. This polishes the edges of the guitar frets. The benefits are that it avoids scratches, ensures playing safety, optimizes the feel, improves playing smoothness, and extends the life of the frets and strings. In addition, the device is compact and easy to carry.

[0013] 2. This device for polishing the edges of guitar frets works by rotating a turntable to drive a lead screw. As the lead screw rotates, the threaded block moves along the groove on the outer surface of the lead screw. When the lead screw moves, the clamping plate also moves simultaneously. After moving to the appropriate position, the insert rod is inserted through the turntable into the limiting plate to limit its position. While the clamping plate moves, the auxiliary block slides on the surface of the auxiliary rod, which can restrict the position of the threaded block. The advantage of this device is that it is easy to fix the device on the guitar, thereby polishing the edges of the guitar frets and preventing slippage, while also providing a good leverage for operation.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] Figures 1-4 The second embodiment is shown, and its main difference from the first embodiment is that: a clamping mechanism is provided on the outer wall of the slide rail 1 for fixing the device. The clamping mechanism includes a clamping frame 12, which is fixed to the outer wall of the slide rail 1. Two connecting blocks 13 are fixedly connected to the outer wall of the slide rail 1. A fixing frame 14 is fixedly connected to the outer wall of the connecting blocks 13. There are two fixing frames 14. A fixing block 15 is fixedly connected to the side of the two fixing frames 14 that are close to each other. A lead screw 18 is rotatably connected to the inner wall of the fixing block 15. A threaded block 19 is threadedly connected to the outer surface of the lead screw 18. A clamping plate 20 is fixedly connected to the bottom of the threaded block 19, and an auxiliary block 17 is fixedly connected to the top of the clamping plate 20. An auxiliary rod 16 is slidably connected to the inner wall of the auxiliary block 17. The outer wall of the auxiliary rod 16 is fixedly connected to the outer wall of the connecting block 13.

The outer wall of the insertion rod 23 penetrates the outer wall of the turntable 21 and extends into the interior of the limiting plate 22.

[0022] Rotating the turntable 21 drives the lead screw 18 fixed on its outer wall to rotate. When the lead screw 18 rotates, the threaded block 19, which is threaded on its outer surface, moves along the groove opened on the outer surface of the lead screw 18. When the lead screw 18 moves, the clamping plate 20 fixed at its bottom also moves at the same time. After moving to a suitable position, the insertion rod 23 is inserted through the turntable 21 into the limiting plate 22 to limit its position. While the clamping plate 20 moves, the auxiliary block 17 fixed at its top slides on the surface of the auxiliary rod 16 to limit the position of the threaded block 19.
