Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of saxophone instrument processing, specifically to a saxophone instrument tone hole processing device. Background Technology

[0002] In the field of saxophone manufacturing and repair, tone hole machining is a crucial step in determining the instrument's sound quality. Saxophone tone holes (such as finger holes and bell holes) require precise grinding to ensure smoothness of the hole walls, consistency of hole diameter, and compatibility with the keys. The machining precision directly affects airflow efficiency, thus determining the stability of pitch and timbre. As saxophone players' demands for sound quality increase, the shortcomings of traditional tone hole machining methods become increasingly apparent: current saxophone tone hole grinding generally relies on manual hand-held operation, lacking stable positioning and support structures, easily leading to uneven grinding. This not only affects the instrument's acoustic performance but also reduces its appearance quality, making it difficult to meet the demands of high-precision machining. In traditional hand-held sanding methods, the operator needs to hold the saxophone body with one hand while using the other to process the tone holes with sanding tools (such as a grinding wheel or sandpaper). Because the saxophone body has an irregular curved surface structure, hand-held sanding can easily lead to inconsistent sanding force and angle due to arm fatigue or slight shaking. Over-sanding in some areas can result in tone holes that are too large, affecting key sealing; under-sanding in some areas can leave burrs and scratches, obstructing airflow and causing intonation deviations. Furthermore, since different tone holes are located in different parts of the saxophone (such as the curved main tube and side tubes), hand-held operation makes it difficult to ensure uniform processing standards for all tone holes, easily leading to inconsistencies in tone hole depth and perpendicularity, further exacerbating differences in sound quality.

[0003] Therefore, developing saxophone tone hole processing equipment with stable positioning and precise grinding functions has become an urgent need to improve the quality of instruments and processing efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a saxophone tone hole processing device, which solves the technical problem that the existing saxophone tone hole grinding operations generally rely on manual hand-held saxophone operation, lack stable positioning and support structure, and are prone to uneven grinding.

[0005] According to one aspect, at least one embodiment of this disclosure provides a saxophone tone hole processing apparatus, comprising: A base and an outer bracket, wherein the outer bracket is fixed to the base; A support flipping assembly is disposed on the base; The transmission cavity and the grinding assembly are provided, wherein the transmission cavity is formed on the side surface of the outer support and the grinding assembly is disposed in the transmission cavity; The support and flipping assembly includes a rotating sleeve, which is horizontally rotatably fitted inside the side surface of the base. One end of the rotating sleeve is fixedly connected to an outer sleeve, and bolts are threadedly connected to both the upper and lower ends of the outer sleeve. A clamping sleeve is rotatably fitted to the lower end of the bolt.

[0006] As a further technical solution, a rectangular groove is provided at one end of the surface of the base, and several guide slide rods are horizontally fixedly connected in the rectangular groove. A movable frame is horizontally slidably connected to the guide slide rods, and a first spring is fitted on each guide slide rod.

[0007] As a further technical solution, a support block is horizontally rotatably connected to the side surface of the mobile frame via a rotating shaft, and an operating wheel is provided at the other end of the rotating shaft of the support block, and a handle is provided at the top of the mobile frame.

[0008] According to another aspect, in at least one embodiment of the present invention, the grinding assembly includes a crossbar, which is horizontally fixed in the transmission cavity, and a movable seat is horizontally slidably connected to the crossbar, with a groove formed on the side surface of the movable seat.

[0009] As a further technical solution, a pair of columns are vertically fixedly connected in the groove, and a lifting seat is vertically slidably connected to the columns. A second spring is fitted on each column, and the second spring is supported between the bottom of the groove and the bottom of the lifting seat.

[0010] As a further technical solution, a drive motor is vertically mounted on the top of the lifting seat, and a conical grinding head is inserted into the output end of the drive motor. The conical grinding head is fixedly connected to the output end of the drive motor by bolts.

[0011] As a further technical solution, the support block has an overall conical structure, and the surface of the support block is an anti-slip surface.

[0012] As a further technical solution, handles are provided on both ends of the lifting seat.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the support flipping assembly solves the problems of instability and limited angle in traditional handheld operation through a stable clamping and flexible angle adjustment design. The outer sleeve and clamping sleeve work together, and the tightening of the bolts provides uniform clamping force, preventing the saxophone from shifting. The rotating sleeve drives the outer sleeve to flip, and with the angle adjustment of the support block, it can adapt to different tone holes on the saxophone, eliminating the need for frequent movement of the equipment. The guide slide and the first spring allow the moving frame to adapt to the length of the saxophone, the tapered support block enhances end stability, and the anti-slip surface prevents slippage. This structure achieves multi-directional stable fixation and flexible angle adjustment of the saxophone, laying the foundation for precise grinding of the grinding assembly, avoiding grinding deviations caused by manual handling, ensuring consistent tone hole processing, and improving the sound quality and appearance of the saxophone.

[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] like Figures 1-3 As shown, it illustrates a sound hole processing apparatus for a saxophone instrument according to an embodiment of the present disclosure, comprising: The base 1 and the outer bracket 2 are fixed on the base 1; A support flipping assembly 4 is provided on the base 1; The transmission cavity 3 and the grinding assembly 5 are provided. The transmission cavity 3 is formed on the side surface of the outer support 2, and the grinding assembly 5 is disposed in the transmission cavity 3. The supporting flipping assembly 4 includes a rotating sleeve 4-1, which is horizontally rotatably fitted inside the side surface of the base 1. One end of the rotating sleeve 4-1 is fixedly connected to an outer sleeve 4-2. Both the upper and lower ends of the outer sleeve 4-2 are threadedly connected to bolts 4-3. The lower end of the bolts 4-3 is rotatably fitted to a clamping sleeve 4-4. One end of the surface of the base 1 has a rectangular groove 4-5. Several guide slide rods 4-6 are horizontally fixedly connected inside the rectangular groove 4-5. A movable frame 4-7 is horizontally slidably fitted onto the guide slide rods 4-6. Each guide slide rod 4-6 is fitted with a first spring 4-8. The side surface of the movable frame 4-7 is horizontally rotatably connected to a support block 4-9 via a rotating shaft. The other end of the rotating shaft of the support block 4-9 is provided with an operating wheel 4-10. The top of the movable frame 4-7 is provided with a handle 4-11.

[0023] In some examples, in order to achieve a stable clamping and multi-angle rotation of the saxophone and avoid the instrument shifting or inconvenient angle during tone hole grinding, a support and rotation component 4 is designed. This component includes a rotating sleeve 4-1 that rotates horizontally within the side surface of the base 1 to provide a mounting and rotation carrier for the outer sleeve 4-2. One end of the outer sleeve 4-2 is fixedly connected to the rotating sleeve 4-1 and can rotate synchronously with the rotating sleeve 4-1, thereby driving the clamped saxophone to rotate as a whole, adjusting the angle of the tone hole toward the grinding hole component 5, which is convenient for grinding tone holes in different positions.

[0024] The upper and lower ends of the outer sleeve 4-2 are fitted with threaded bolts 4-3. The position of the lower clamping sleeve 4-4 can be adjusted by screwing them. After placing one end of the saxophone into the outer sleeve 4-2, screwing the upper and lower bolts 4-3 will make the clamping sleeve 4-4 fit and clamp the saxophone from the upper and lower sides. The self-locking characteristic of the threads keeps the clamping force stable and prevents the saxophone from shifting axially or radially during grinding.

[0025] The rotating assembly design of the clamping sleeve 4-4 and the bolt 4-3 ensures that the clamping sleeve 4-4 only moves in a straight line when the bolt 4-3 is tightened, and does not rotate with the bolt 4-3, thus avoiding damage to the saxophone surface.

[0026] The guide rod 4-6 in the rectangular groove 4-5 on the surface of the base 1 provides horizontal sliding guidance for the movable frame 4-7. The support block 4-9, which is rotatably connected to the side surface of the movable frame 4-7 via a rotating shaft, can provide support from the other end of the saxophone. Together with the outer sleeve 4-2, it forms a two-end support structure, which enhances the stability of the saxophone. The first spring 4-8 on the guide rod 4-6 provides elastic thrust to the movable frame 4-7, so that the support block 4-9 always fits the end of the saxophone, which can accommodate saxophones of different lengths without the need for frequent adjustment of the position of the movable frame 4-7.

[0027] The operating wheel 4-10 can drive the support block 4-9 to rotate around the rotating axis, further fine-tuning the saxophone angle and ensuring that the tone hole is accurately aligned with the grinding hole assembly 5. The handle 4-11 makes it easy to manually push the moving frame 4-7 to adjust the distance between the support block 4-9 and the outer cover 4-2, making it convenient to put the saxophone in and out.

[0028] During operation, push the movable frame 4-7 into the saxophone, tighten the bolt 4-3, and rotate the outer sleeve 4-2 or the operating wheel 4-10 to adjust the angle, providing a precise machining station for the grinding hole assembly 5. The clamping at both ends ensures stability, and the flexible rotation accommodates multiple tone holes. All components work together to fix the saxophone and adjust its angle, meeting the requirements for tone hole processing.

[0029] like Figures 1-3 As shown in the figure, the grinding assembly 5 in this embodiment includes a crossbar 5-1, which is horizontally fixed in the transmission cavity 3. A movable seat 5-2 is horizontally slidably connected to the crossbar 5-1. A groove 5-3 is formed on the side surface of the movable seat 5-2. A pair of columns 5-4 are vertically fixedly connected in the groove 5-3. A lifting seat 5-5 is vertically slidably connected to the column 5-4. A second spring 5-6 is fitted on each column 5-4. The second spring 5-6 is supported between the bottom of the groove 5-3 and the bottom of the lifting seat 5-5. A drive motor 5-7 is vertically mounted on the top of the lifting seat 5-5. A conical grinding head 5-8 is inserted into the output end of the drive motor 5-7. The conical grinding head 5-8 and the output end of the drive motor 5-7 are fixedly connected by bolts 4-3.

[0030] In some examples, in order to achieve precise grinding of the saxophone tone holes and avoid deformation or insufficient precision caused by grinding position deviation or uneven pressure, a grinding assembly 5 is designed. This assembly includes a horizontally fixed crossbar 5-1 in the transmission cavity 3 to provide horizontal sliding support for the moving seat 5-2. The moving seat 5-2 can be adjusted in horizontal position along the crossbar 5-1 to adapt to the grinding requirements of tone holes in different positions of the saxophone, ensuring that the conical grinding head 5-8 can be accurately aligned with the center of the tone hole and avoiding grinding deviation.

[0031] The column 5-4 in the groove 5-3 on the side surface of the movable seat 5-2 provides a vertical sliding guide for the lifting seat 5-5. The second spring 5-6 on the column 5-4 is supported between the bottom of the groove 5-3 and the lifting seat 5-5, providing upward elastic support for the lifting seat 5-5. This facilitates manual pressing of the lifting seat 5-5 to control the grinding depth and avoids excessive grinding pressure that could lead to over-grinding of the sound hole.

[0032] The drive motor 5-7 on the top of the lifting seat 5-5 provides rotational power to the conical grinding head 5-8. The output end of the drive motor 5-7 is fixedly connected to the conical grinding head 5-8 by bolts 4-3, which facilitates the replacement of grinding heads of different specifications according to the size of the tone hole, improving the adaptability of the device to tone holes of multiple specifications. The conical structure of the conical grinding head 5-8 is adapted to the shape of the saxophone tone hole, which is larger on the outside and smaller on the inside. It can grind from the inner wall of the tone hole outwards step by step, ensuring that the inner wall of the tone hole is smooth and the size is accurate, avoiding damage to the edge of the tone hole caused by the right-angle grinding head.

[0033] The elastic force of the second spring 5-6 can be adjusted according to the grinding requirements. It can not only help the operator to easily control the downward pressure, but also buffer the vibration during the grinding process, reduce the rigid collision between the grinding head and the tone hole, and extend the service life of the grinding head. The combination of the horizontal sliding of the moving seat 5-2 and the vertical movement of the lifting seat 5-5 can cover tone holes at different positions and angles on the saxophone surface, without the need to frequently adjust the angle of the support flipping component 4, thus improving processing efficiency. During operation, the sliding seat 5-2 is aligned with the tone hole, and the lifting seat 5-5 is manually pressed down to allow the rotating conical grinding head 5-8 to extend into the tone hole for grinding. The second spring 5-6 assists in controlling the pressure and resetting. Multi-directional adjustment adapts to multiple tone holes, elastic pressing ensures accuracy, and all components work together to complete the precise grinding of the tone holes, meeting the processing requirements of saxophone tone holes.

[0034] For example, such as Figure 2 As shown, the support block 4-9 has an overall conical structure, and the surface of the support block 4-9 is an anti-slip surface.

[0035] In some examples, the overall tapered structure of the support block 4-9 can adapt to different sizes of the saxophone end, allowing the support block 4-9 to be precisely embedded inside the saxophone end or conform to its external contour, forming a adaptive support and preventing instability caused by size mismatch between the support block 4-9 and the saxophone end. Furthermore, the anti-slip surface of the support block 4-9 increases the friction with the saxophone end, preventing axial slippage of the saxophone due to vibration during polishing.

[0036] For example, such as Figure 1 As shown, handles 6 are provided on both ends of the lifting seat 5-5.

[0037] In some examples, the handles 6 on both sides of the lifting seat 5-5 provide convenient points of force for the operator to manually press down the lifting seat 5-5. Compared to directly pressing the top of the lifting seat 5-5, the handles 6 are ergonomically designed, allowing the operator to hold the handles 6 with both hands to apply force evenly and easily control the pressing speed and force of the lifting seat 5-5. This avoids tilting of the lifting seat 5-5 due to single-handed operation, and thus prevents excessive friction between the conical grinding head 5-8 and the inner wall of the sound hole on one side.

[0038] In actual use: Hold the handle 4-11 of the support flipping assembly 4, push the moving frame 4-7 to slide along the guide rod 4-6 of the rectangular groove 4-5, compress the first spring 4-8 and widen the gap with the outer casing 4-2, put one end of the saxophone into the outer casing 4-2, and align the other end with the conical support block 4-9. Tighten the bolts 4-3 on the upper and lower parts of the outer casing 4-2, causing the clamping sleeve 4-4 to clamp the saxophone from both sides. The anti-slip support block 4-9 presses against the end of the saxophone under the action of the first spring 4-8, forming a fixed end. Rotate the outer casing 4-2 by rotating the sleeve 4-1, or rotate the operating wheel 4-10 to adjust the angle of the support block 4-9 so that the tone hole to be ground is aligned with the grinding assembly 5. Hold the handle 6 of the grinding assembly 5, slide the moving base 5-2 along the crossbar 5-1 to adjust its horizontal position, align the conical grinding head 5-8 with the tone hole, start the drive motor 5-7, manually press down the lifting base 5-5, the second spring 5-6 buffers the pressure, and the conical grinding head 5-8 evenly grinds the tone hole. After grinding, release the lifting base 5-5, the second spring 5-6 returns to its original position, turn off the motor, and loosen the bolt 4-3 to remove the saxophone. The entire process achieves stable fixation of the saxophone and precise grinding of the tone hole without manual handling.
