[0002] In the field of musical instrument manufacturing, the cylinder, as the core sound-producing component of brass instruments, has a significant impact on the accuracy of sound production during performance due to its machining precision. Consequently, its machining process requires high precision. Currently, the industry generally relies on general-purpose boring machines to machine instrument cylinders. These boring machines are typically used for machining common mechanical parts, and their fixtures are mostly standardized designs. They cannot flexibly match instrument cylinders of specific specifications and shapes, resulting in inaccurate and unstable clamping of the instrument cylinder by the fixtures. This can easily cause the boring machine to deviate during the machining of the instrument cylinder, affecting the machining precision.

[0021] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0022] In the field of musical instrument manufacturing, the cylinder is a crucial sound-producing component in brass instruments (such as trumpets, euphoniums, and barre euphoniums). Its machining precision directly affects the subsequent assembly accuracy with the piston, the smoothness of movement, and the sealing performance. If the roundness and straightness of the cylinder's inner bore do not meet standards, it can lead to piston jamming and air leakage, causing fluctuations in airflow pressure. This, in turn, affects the instrument's intonation, tone stability, and performance, and may also accelerate component wear. Therefore, high precision is required for the machining of instrument cylinders. However, currently, the industry generally relies on traditional general-purpose boring machines for machining instrument cylinders. These boring machines are designed to accommodate standardized, mass-produced general-purpose mechanical parts in the machinery manufacturing field (such as motor bushings and hydraulic cylinder bodies), and their fixtures are mostly based on standard dimensions. However, since musical instrument cylinders come in various sizes and specifications, the standardized fixtures of general-purpose boring machines are difficult to accurately and stably clamp for different sizes of musical instrument cylinders. This makes it difficult to precisely align the machining parts of the boring machine and the musical instrument cylinder, resulting in deviations such as axial offset, radial oscillation, or tilting of the machining surface when the cylinder is machined by the boring machine. This not only affects the sound quality of the musical instrument, but may also increase the difficulty of assembling other components (such as musical instrument pistons) with the musical instrument cylinder.

[0023] To address the above problems, this embodiment provides a boring machine for machining musical instrument cylinders, comprising: Multiple clamping mechanisms 1, the clamping surfaces of the multiple clamping mechanisms 1 are adapted to clamp musical instrument cylinders of different sizes to be processed; Boring assembly 2 is located on the top surface of the boring machine bed 4 and is used to bore the instrument cylinder to be machined; The support adjustment component 3 is disposed on the top surface of the boring machine bed 4 and is detachably connected to the clamping mechanism 1. The support adjustment component 3 is used to drive the clamping mechanism 1 to move along the first direction to adjust the relative position of the instrument cylinder to be processed and the boring component 2, so as to complete the boring of the instrument cylinder to be processed.

[0024] For details, please refer to Figure 1 Multiple clamping mechanisms 1 have clamping surfaces adapted to clamp instrument cylinders of different sizes to be processed. During processing, the appropriate clamping mechanism 1 can be selected according to the different sizes of instrument cylinders (such as instrument cylinders with different outer diameters and shapes) to achieve accurate and stable clamping of the instrument cylinder to be processed. The boring assembly 2 is set on the top surface of the boring machine bed 4 and is used to bore the instrument cylinder to be processed held by the clamping mechanism 1. The support adjustment assembly 3 is set on the top surface of the boring machine bed 4 and is detachably connected to the clamping mechanism 1, so that the clamping mechanism 1 can be flexibly replaced according to the different sizes of the instrument cylinder. The detachable connection between the clamping mechanism 1 and the support adjustment assembly 3 allows for flexible adjustment of the position of the clamping mechanism 1, so that the boring assembly 2 is aligned with the part of the instrument cylinder to be processed held by the clamping mechanism 1. The support adjustment assembly 3 is used to drive the clamping mechanism 1 to move along a first direction, so as to adjust the relative position of the instrument cylinder to be processed and the boring assembly 2, so that the boring assembly 2 can be stably contacted and bored after being aligned with the part to be processed of the instrument cylinder. The first direction is the axial direction of the instrument cylinder to be processed, and is... Figure 1 The X-axis direction. In addition, a button assembly 9 and a power supply 10 are also provided on the boring machine bed 4. The power supply 10 is used to provide power support for the boring machine's machining process. The button assembly 9 includes a start button, an emergency stop button, a reset button, etc., which are used to control the boring machine's start-up, emergency stop, and equipment reset, respectively. The number and function of the buttons can be arranged according to the actual situation, and no specific limitation is made here.

[0025] This application utilizes multiple clamping mechanisms with clamping surfaces adapted to different sizes of musical instrument cylinders to achieve accurate clamping of cylinders of varying sizes. A support adjustment component can drive the clamping mechanism to move along a first direction, and the support adjustment component is detachably connected to the clamping mechanism. This allows the relative position of the instrument cylinder to be processed, clamped by the clamping mechanism, and the boring component to be adjusted according to the processing requirements of the instrument cylinder (such as different cylinder lengths or different processing locations). This precise clamping of the instrument cylinder enables the boring component of the boring machine to process the accurate position of the instrument cylinder, solving the processing deviation problem of traditional general-purpose boring machines and improving the processing accuracy of the instrument cylinder.

[0026] In a preferred embodiment, the support adjustment component 3 includes: Mounting plate 31, mounting plate 31 is used to mount clamping mechanism 1; The sliding guide includes two parallel slide rails 321 extending in a first direction, and the two slide rails 321 are slidably connected to the mounting plate 31 respectively. The first driving member 33 is fixedly connected to the boring machine bed 4, and the driving end of the first driving member 33 is connected to the mounting plate 31 for driving the mounting plate 31 and the clamping mechanism 1 to slide along the first direction on the sliding guide.

[0027] Specifically, such as Figure 2 As shown, the mounting plate 31 is used to mount the clamping mechanism 1; the sliding guide includes two parallel slide rails 321 extending in a first direction, and the two slide rails 321 are slidably connected to the mounting plate 31 via sliders 322 respectively; the first drive member 33 is fixedly connected to the boring machine bed 4, and the drive end of the first drive member 33 is connected to the mounting plate 31 for driving the mounting plate 31 and the clamping mechanism 1 to slide along the first direction on the sliding guide 32. In this embodiment, the driving end of the first driving member 33 is connected to the mounting plate 31 via a lead screw 323 and a matching lead screw nut 324. Specifically, the lead screw 323 extends along the first direction and is disposed between the two slide rails 321. One end of the lead screw 323 is fixedly connected to the driving end of the first driving member 33, and the other end is rotatably connected to the fixed seat 325 disposed on the boring machine bed. The bottom surface of the mounting plate 31 is equipped with a lead screw nut 324, which is connected to the lead screw 323. After the first driving member 33 is started, its driving end drives the lead screw 323 to rotate. The lead screw 323 converts the rotational motion into linear motion through the cooperation with the lead screw nut 324, thereby driving the mounting plate 31 and the clamping mechanism 1 to slide along the first direction on the slide rail 321.

[0028] In a preferred embodiment, the top surface of the mounting plate 31 has a plurality of parallel mounting slots 311. After the mounting plate 31 is moved to the initial position, the clamping mechanism 1 is installed in the preset position of the mounting slot 311, and the mounting plate 31 and the clamping mechanism 1 are detachably connected. The preset position is determined according to the length of the instrument cylinder to be processed, and the initial position is the end of the slide rail 321 away from the boring component 2.

[0029] Specifically, such as Figure 1 and Figure 2As shown, the top surface of the mounting plate 31 has multiple parallel mounting slots 311. After the mounting plate 31 moves to the initial position, the clamping mechanism 1 is installed in the preset position of the mounting slot 311, and the mounting plate 31 and the clamping mechanism 1 are detachably connected. The initial position is the end of the slide rail 321 away from the boring assembly 2. The preset position is determined according to the length of the instrument cylinder to be processed. The preset position is a position that allows the instrument cylinder to be processed to just contact the end of the boring assembly 2 or to maintain a certain distance, so as to accommodate instrument cylinders of different lengths. Specifically, the distance between the preset position and the end of the boring assembly 2 needs to be greater than or equal to the length of the instrument cylinder to be processed, so that the instrument cylinder to be processed just contactes the end of the boring assembly 2 or maintains a certain distance, in order to ensure that the processing can proceed normally.

[0030] In a preferred embodiment, the clamping mechanism 1 includes: Base 11, which is detachably connected to mounting plate 31; The clamping assembly 12 includes a first clamping part 121 disposed on the base 11 and a second clamping part 122 disposed corresponding to the first clamping part 121. The first clamping part 121 and the second clamping part 122 are respectively provided with clamping surfaces adapted to the instrument cylinder to be processed, and the second clamping part 122 can move along a second direction to form a clamping space with the first clamping part 121. The clamping space is used to accommodate the instrument cylinder to be processed. The second direction is perpendicular to the first direction.

[0031] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the base 11 and the mounting plate 31 are detachably connected. In this embodiment, the base 11 is installed in the corresponding mounting groove 311 by a fastener 123. The bottom of the fastener 123 can be embedded in the groove of the mounting groove 311 and can slide in the mounting groove 311. After its top passes through the base 11, it is tightened with a nut. By tightening and loosening the bolt, the base 11 can be fixed and disassembled on the mounting plate 31, realizing the detachable connection between the base 11 and the mounting plate 31. The base 11 also provides a stable mounting reference for the clamping assembly 12. The clamping assembly 12 includes a first clamping part 121 disposed on the base 11 and a second clamping part 122 disposed corresponding to the first clamping part 121. The first clamping part 121 and the second clamping part 122 are respectively provided with clamping surfaces adapted to the instrument cylinder to be processed, and the second clamping part 122 can move along a second direction to form a clamping space with the first clamping part 121. The clamping space is used to accommodate the instrument cylinder to be processed. The second direction is perpendicular to the first direction and is... Figure 1 The Z-axis direction in the equation.

[0032] In a preferred embodiment, the base 11 includes: U-shaped base 111, U-shaped base 111 is detachably connected to mounting plate 31; Two support arms 112 are respectively disposed on the top surfaces of both ends of the U-shaped base 111, and both support arms 112 extend along the second direction and are arranged in parallel.

[0033] Specifically, such as Figure 3 As shown, the base 11 consists of a U-shaped base 111 and two support arms 112. The U-shaped base 111 is installed in the corresponding mounting slot 311 by a fastener 123, achieving a detachable connection with the mounting plate 31. The two support arms 112 are respectively disposed on the top surfaces of both ends of the U-shaped base 111. Both support arms 112 extend along the second direction and remain parallel. The parallel arrangement of the two support arms 112 on the top surfaces of both ends of the U-shaped base 111 ensures a certain distance between them, reserving space for the placement and passage of the instrument cylinder to be processed, and avoiding interference with the base 11. Furthermore, the two support arms 112 are L-shaped, with one end fixedly connected to the top surface of the U-shaped base 11 and extending in the second direction, and the other end extending in the third direction, providing an installation reference for the first clamping part 121 and the second clamping part 122 of the clamping assembly 12, so that the clamping surfaces of the first clamping part 121 and the second clamping part 122 can be in the same plane, further ensuring the accurate and stable clamping of the instrument cylinder to be processed. The third direction is perpendicular to the plane formed by the first and second directions, and is Figure 1 The Y-axis direction in the diagram.

[0034] In a preferred embodiment, the clamping assembly 12 includes: The first clamping part 121 consists of two parts. The two first clamping parts 121 are arranged parallel to each other along the second direction. The ends of the two first clamping parts 121 that are away from the U-shaped base 111 pass through the two support arms 112 respectively. The end of the first clamping part 121 that is close to the U-shaped base 111 is provided with a clamping surface that is adapted to the instrument cylinder to be processed. The second clamping part 122 consists of two parts, each corresponding to one of the two first clamping parts 121, and is located on the top surface of both ends of the U-shaped base 111. The two second clamping parts 122 extend along the second direction and are arranged in parallel. The end of the second clamping part 122 away from the mounting plate 31 is provided with a clamping surface adapted to the instrument cylinder to be processed.

[0035] Specifically, such as Figure 3As shown, the clamping assembly 12 includes two first clamping portions 121 and two second clamping portions 122. The two first clamping portions 121 are arranged parallel to each other along a second direction, and the ends of the two first clamping portions 121 away from the U-shaped base 111 are rod-shaped, each penetrating through one of the two support arms 112. The ends of the two first clamping portions 121 near the U-shaped base 111 are provided with clamping surfaces adapted to the instrument cylinder to be processed. The two second clamping portions 122 are respectively arranged corresponding to the two first clamping portions 121 and are located on the top surfaces of both ends of the U-shaped base 111. The two second clamping portions 122 extend along the second direction and are arranged parallel to each other, and the ends of the second clamping portions 122 away from the mounting plate 31 are provided with clamping surfaces adapted to the instrument cylinder to be processed. In this embodiment, the rod-shaped end of the first clamping part 121 away from the U-shaped base 111 is threaded to the connection part of the support arm 112. When the rod-shaped end of the first clamping part 121 away from the U-shaped base 111 is rotated, the first clamping part 121 will move up and down along the second direction (Z-axis), thereby moving closer to or away from the second clamping part 122, thus adjusting the relative position between the two to clamp instrument cylinders of different specifications. However, other connection methods that allow the first clamping part 121 to move along the second direction can also be used, and no specific limitation is made here.

[0036] In a preferred embodiment, the boring assembly 2 includes: The boring part 21 is shaped to fit the instrument cylinder to be machined, and the axis of the boring part 21 coincides with the axis of the instrument cylinder to be machined, and is used to bore the instrument cylinder to be machined. The second driving component 22 is fixedly connected to the top surface of the boring machine bed 4, and its driving end is connected to the boring part 21 to drive the boring part 21 to rotate in order to complete the boring of the instrument cylinder to be machined.

[0037] Specifically, such as Figure 1 As shown, the boring assembly 2 includes a boring piece 21 and a second drive member 22. The shape of the boring piece 21 is adapted to the instrument cylinder to be machined, and the axis of the boring piece 21 coincides with the axis (first direction) of the instrument cylinder to be machined, ensuring that the boring piece 21 does not have positional deviation when machining the instrument cylinder, thereby improving the machining accuracy of the instrument cylinder. The second drive member 22 is disposed on the top of the boring machine bed 4, and its drive end is connected to the boring piece 21. After the second drive member 22 is started, its drive end drives the boring piece 21 to rotate, so as to complete the boring of the instrument cylinder to be machined.

[0038] In a preferred embodiment, the boring machine further includes a first controller 5 and a second controller 6. The first controller 5 and the second controller 6 are disposed on the side of the boring machine bed 4 and are electrically connected to the first drive member 33 and the second drive member 22 respectively, for controlling the rotational speed of the first drive member 33 and the second drive member 22.

[0039] Specifically, such as Figure 1 As shown, the boring machine also includes a first controller 5 and a second controller 6. The first controller 5 and the second controller 6 are located on the side of the boring machine bed 4 and are electrically connected to the first drive member 33 and the second drive member 22, respectively. The first controller 5 controls the rotational speed of the first drive member 33, enabling the mounting plate 31 and the clamping mechanism 1 to move smoothly along the first direction with the instrument cylinder to be processed, accurately adjusting the relative position of the instrument cylinder to be processed and the boring workpiece 21, avoiding positioning deviation due to excessive movement speed or affecting processing efficiency due to excessively slow movement speed. The second controller 6 controls the rotational speed of the second drive member 22, allowing the boring workpiece 21 to select different rotational speeds according to different processing requirements of the instrument cylinder. For example, for instrument cylinders made of brass, copper, or other metals, a higher processing speed can be selected to improve cutting efficiency and ensure surface finish; for instrument cylinders made of stainless steel, alloys, or other hard metals, a relatively lower processing speed is selected to avoid wear or breakage of the boring workpiece 21 due to excessive load.

[0040] In a preferred embodiment, the boring machine further includes a support member 7, which is disposed between the second drive member 22 and the boring machine bed 4, and its bottom surface is fixedly connected to the boring machine bed 4, and its top surface is fixedly connected to the bottom of the second drive member 22, so that the axial height of the boring part 21 connected to the second drive member 22 is the same as the axial height of the instrument cylinder.

[0041] Specifically, such as Figure 1 As shown, the boring machine also includes a support member 7, which is disposed between the second drive member 22 and the boring machine bed 4. Its bottom surface is fixedly connected to the boring machine bed 4, and its top surface is fixedly connected to the bottom of the second drive member 22. In this embodiment, the support member 7 is box-shaped and is fixedly connected to the boring machine bed 4 and the second drive member 22 by bolts. However, other fixing methods can also be used, and no specific limitation is made here. The purpose of setting the support member 7 between the second drive member 22 and the boring machine bed 4 is to compensate for the height difference between the second drive member 22 and the clamping mechanism 1, so that the axial height of the boring workpiece 21 connected to the second drive member 22 is the same as the axial height of the instrument cylinder. This avoids defects such as eccentricity or uneven wall thickness in the boring instrument cylinder due to height deviation between the two axes, thereby improving the machining accuracy of the instrument cylinder.

[0042] In a preferred embodiment, the boring machine further includes a dustproof component 8, which includes: The first dust cover 81 is disposed above the first drive component 33 and is fixedly connected to the boring machine bed 4; The second dust cover 82 is retractable, with one end fixedly connected to the support member 7 and the other end fixedly connected to the mounting plate 31.

[0043] Specifically, such as Figure 1 As shown, the boring machine also includes a dustproof assembly 8, which includes a first dust cover 81 and a second dust cover 82. The first dust cover 81 is disposed above the first drive member 33 and is fixedly connected to the boring machine bed 4. It is used to prevent metal chips and dust generated during the machining process from splashing onto the first drive member 33, thereby improving the service life of the first drive member 33. The second dust cover 82 is retractable, with one end fixedly connected to the support member 7 and the other end fixedly connected to the mounting plate 31. It can prevent metal chips and dust from entering the gap of the slide rail 321 and avoid the mounting plate 31 from getting stuck when moving. At the same time, the retractable structure of the second dust cover 82 is adapted to the reciprocating movement of the mounting plate 31 along the first direction, without affecting the normal machining stroke of the equipment.

[0044] The boring machine for machining musical instrument cylinders provided in this application achieves accurate clamping of musical instrument cylinders of different sizes by setting multiple clamping mechanisms adapted to different sizes of musical instrument cylinders to be machined. The support adjustment component can drive the clamping mechanism to move along a first direction, and the support adjustment component is detachably connected to the clamping mechanism. This allows the relative position of the musical instrument cylinder to be machined held by the clamping mechanism and the boring component to be adjusted according to the machining requirements of the musical instrument cylinder (such as different lengths of the musical instrument cylinder or different machining parts of the musical instrument cylinder). The mechanical boring machine can accurately clamp the musical instrument cylinder to be machined, so that the boring component of the boring machine can machine the accurate position of the musical instrument cylinder. This solves the problem of poor machining accuracy caused by poor clamping adaptability and insufficient positioning accuracy of traditional general-purpose boring machines, and improves the machining accuracy of musical instrument cylinders. The first and second controllers respectively control the rotational speeds of the first and second drive components. The first controller controls the movement speed of the mounting plate and clamping mechanism to avoid positioning deviations caused by rapid movement or low processing efficiency caused by slow movement. The second controller controls different rotational speeds according to the different processing requirements of the instrument cylinders to be processed, preventing inefficient processing of soft materials or tool wear on hard materials, thus ensuring processing stability. The dustproof component protects the first drive component, slide rails, etc. from contamination and wear by shielding them from metal chips, dust, and cutting fluid, thereby improving the service life of the equipment and reducing maintenance costs.

[0045] To facilitate understanding by those skilled in the art, the working process of the boring machine for machining musical instrument cylinders provided in this application is as follows: Select a suitable clamping mechanism 1 according to the size of the instrument cylinder to be processed, and determine the preset position of the mounting groove 311 on the mounting plate 31 according to the length of the instrument cylinder to be processed; install the U-shaped base 111 of the clamping mechanism 1 into the preset position of the mounting groove 311; place the instrument cylinder to be processed into the clamping space between the two first clamping parts 121 and the two corresponding second clamping parts 122; the second driving member 22 drives the boring part 21 to rotate, and at the same time the first driving member 33 supporting the adjustment component 3 drives the mounting plate 31 to move along the first direction, causing the instrument cylinder to be processed held by the clamping mechanism 1 to move closer to the boring part 21 of the boring component 2, so that the boring part 21 contacts the instrument cylinder to be processed and completes the boring; the first driving member 33 drives the mounting plate 31 and the clamping mechanism 1 to reset to the initial position.

[0046] The boring machine for machining musical instrument cylinders provided in this application achieves accurate clamping of cylinders of different sizes by setting up multiple clamping mechanisms adapted to different sizes of musical instrument cylinders to be machined. A support adjustment component can drive the clamping mechanism to move along a first direction, and the support adjustment component is detachably connected to the clamping mechanism. This allows the relative position of the instrument cylinder to be machined and the boring component to be adjusted according to the machining requirements of the instrument cylinder (such as different cylinder lengths or different machining parts). This precise clamping of the instrument cylinder enables the boring component of the boring machine to machine the accurate position of the instrument cylinder, solving the problem of poor machining accuracy caused by poor clamping adaptability and insufficient positioning accuracy in traditional general-purpose boring machines, thus improving the machining accuracy of musical instrument cylinders. Furthermore, the improved machining accuracy of the cylinder can reduce the amount of machining in the subsequent honing process (final grinding of the workpiece's inner hole), thereby reducing machining time and improving production efficiency.
