Description

Technical Field

[0001] This invention relates to the field of musical instrument processing technology, and in particular to a hole wall grinding device for processing accordion instrument parts. Background Technology

[0002] As a keyboard instrument that combines melodic and harmonic expression, the accordion's sound production system is composed of a series of precision components. Among them, the metal components with perforated structures are the core components that ensure the accuracy of sound production and the smoothness of airflow. The quality of the perforation wall processing of these components directly affects the acoustic performance of the accordion. Burrs and excessive roughness on the surface of the perforation wall can lead to airflow disturbance, causing problems such as timbre distortion and pitch deviation. On the other hand, high-precision smooth perforation walls can ensure stable airflow, allowing the instrument to present a pure and full sound quality. Therefore, in the production and processing of accordions, perforation wall polishing is a crucial precision processing step.

[0003] Existing accordion component hole wall grinding equipment suffers from several technical challenges in practical applications: First, insufficient clamping stability. Traditional clamping mechanisms often employ rigid clamping methods, lacking pressure feedback and limit adjustment functions. Excessive clamping pressure can easily cause indentations, deformation, or warping on the component surface, while insufficient pressure may lead to material displacement during grinding, severely affecting processing accuracy. Second, significant dust pollution. Metal dust generated during grinding easily adheres to the inner side of the hole wall and the surface of the component. If not cleaned in time, it can not only scratch the already smooth hole wall, causing excessive roughness rebound, but also contaminate the equipment's transmission components, shortening the equipment's lifespan. Third, thermal deformation of the grinding head affects accuracy. The grinding head of the grinding mechanism generates a large amount of heat during continuous high-speed grinding. Existing equipment lacks a targeted and efficient cooling structure, and the accumulation of heat can cause thermal expansion or deformation of the grinding head, resulting in uneven grinding depth and dimensional deviations. Fourth, limited positioning accuracy. Traditional positioning methods struggle to achieve precise alignment between the component hole and the grinding head, and the lack of real-time visual monitoring easily leads to grinding position deviations, affecting component assembly compatibility.

[0004] Therefore, this application provides a hole wall grinding device for processing accordion musical instrument parts to meet the needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a hole wall grinding device for processing accordion musical instrument parts, so as to solve the problems that the existing clamping pressure is too high, which will cause scratches or deformation on the material surface; the metal dust generated during the grinding process will scratch the hole if it is not treated in time, resulting in excessive roughness; and the grinding head will generate a lot of heat during continuous grinding, which will cause the grinding head to deform and affect the grinding accuracy.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A hole wall grinding device for processing accordion musical instrument parts includes a mounting box. A slide rail is installed on one side of the mounting box, and a first hydraulic rod is installed on the other side of the slide rail. A U-shaped seat is installed at the output end of the first hydraulic rod. A grinding mechanism is installed on the inner side of the top of the U-shaped seat. Cameras are installed on both sides of the top of the mounting box, and several LED lights are arranged on the outer side of each camera. The LED lights are fixedly connected to the inner wall of the mounting box. Clamping assemblies are symmetrically installed on a pair of sides of the mounting box for clamping materials. A positioning assembly is installed at the bottom of the U-shaped seat for positioning the materials. A cooling assembly is installed inside the positioning assembly for cooling the grinding head and cleaning dust during grinding.

[0007] Optionally, the clamping assembly includes a second hydraulic rod, which is installed on the inner wall of the mounting box. The output end of the second hydraulic rod is fixedly connected to a shaped mounting base, and clamping blocks are symmetrically installed at the upper and lower ends of the shaped mounting base.

[0008] Optionally, the clamping assembly further includes a limiting rod, which is fixedly connected to the bottom center of the upper clamping block, and a pressure sensing mechanism is embedded in the top center of the lower clamping block. The number of limiting rods and pressure sensing mechanisms are the same, and they correspond one-to-one.

[0009] Optionally, the positioning component further includes a fixing seat, which is installed on the inner side of the bottom end of the U-shaped seat, and a micro motor is installed on one side of the top end of the fixing seat. The output end of the micro motor is fixedly connected to a first gear.

[0010] Optionally, the positioning component further includes a second gear, which meshes with the outer wall of one end of the first gear. The top of the fixed base is symmetrically connected to a pair of rotating shafts, and a suction cup is fixedly connected to the center of each of the two rotating shafts. One side of the rotating shaft is fixedly connected to the center of the second gear.

[0011] Optionally, the positioning component also includes a belt, which is sleeved on the outer wall of the other side of the rotating shaft. The other end of the belt is connected to the output end of the micro motor. A first vacuum pump is installed on the other side of the top of the fixed base. The outlet of the first vacuum pump is connected to a flexible hose. Both ends of the flexible hose pass through the inner wall of the rotating shaft and are connected to the suction cup.

[0012] Optionally, the cooling assembly includes a cooling cavity, which is located at the center of the fixed base. The interior of the cooling cavity is provided with several V-shaped seats, and several thermally conductive silicone pads are fixedly connected to one end of the outer wall of each V-shaped seat.

[0013] Optionally, the cooling assembly further includes several springs, each of which is fixedly connected to the other end of the V-shaped seat. The other ends of the springs are also fixedly connected to the inner wall of the cooling chamber. The top outer wall of the cooling chamber is provided with spiral cooling holes. A circulation pump is installed on one side of the bottom of the fixed seat, and the outlet of the circulation pump is connected to the spiral cooling holes through a pipe.

[0014] Optionally, the cooling assembly further includes an oil chamber, which is located on the inner wall of the middle part of the fixed base. The interior of the oil chamber is connected to the liquid inlet of the circulating pump, and the other end of the spiral cooling hole is connected to a liquid outlet pipe, which is connected to the oil chamber.

[0015] Optionally, the cooling assembly further includes a plurality of cooling fans, which are installed on the bottom outer wall of the mounting base. A collection frame is installed on the bottom inner wall of the mounting base, and the collection frame is connected to the cooling cavity. A second vacuum pump is installed on the other side of the bottom of the mounting base, and the outlet of the second vacuum pump is connected to the collection frame. A flexible cover is fixedly connected to the top outer wall of the mounting base.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, a limiting rod and a pressure sensing mechanism are incorporated into the clamping assembly. Driven by hydraulic and pneumatic mechanisms, stable clamping and fine-tuning are achieved, protecting the integrity of the material surface. Real-time monitoring of the clamping force prevents indentations, deformation, or warping due to excessive pressure. This avoids the indentation and deformation problems caused by rigid clamping, while the stable transmission of power through hydraulic drive ensures clamping stability and effectively prevents material displacement during grinding. The symmetrical upper and lower clamping blocks and irregularly shaped mounting base design adapt to the clamping needs of different accordion accessories, broadening the equipment's applicability. Furthermore, the clamping process synergizes with the adsorption function of the positioning assembly, further enhancing the reliability of material fixation and laying the foundation for high-precision grinding.

[0017] A micro-motor-driven suction cup achieves rotational adsorption and fixation, positioning the material before and after clamping to ensure accurate grinding position and proper alignment with the suction cup. This prevents material displacement during grinding, improving grinding accuracy and consistency. Simultaneously, LEDs adjust light intensity to provide a clear view for the camera, assisting the operator in real-time monitoring of positioning and the grinding process. Precise positioning in the X and Y directions enhances grinding precision and efficiency. The micro-motor-driven dual-suction cup rotational adsorption structure enables rapid material positioning and angle calibration. Combined with the stable negative pressure adsorption of the first vacuum pump, it ensures the material remains stable during grinding. The camera and LED light group at the top of the mounting box form a visual monitoring system. The LED light intensity can be flexibly adjusted to provide a clear view for the camera, allowing the operator to observe positioning accuracy and grinding progress in real time, promptly identifying and correcting deviations. Furthermore, the combined drive of the slide rail and the first hydraulic rod enables precise displacement adjustment of the grinding mechanism in the X and Y directions, allowing the grinding head to accurately align with the hole wall processing position, significantly improving the positional accuracy and consistency of hole wall grinding and effectively reducing the scrap rate caused by positioning deviations.

[0018] A flexible cover creates a partially enclosed space, effectively utilizing negative pressure to remove metal dust during grinding, preventing dust accumulation in the gap between the hole wall and the grinding head. The built-in filter in the collection frame captures dust and prevents it from entering the vacuum pump, extending equipment life and maintaining a clean working environment. Simultaneously, after the grinding head enters the cooling chamber, thermally conductive silicone transfers the heat from the grinding head to the V-shaped seat, and then the V-shaped seat transfers the heat to the cooling chamber wall. Finally, cooling oil circulates in the spiral cooling holes, quickly dissipating the heat from the grinding head. This prevents the grinding head from expanding or deforming due to high temperatures, achieving efficient heat exchange, further improving cooling efficiency, and ensuring the grinding head maintains stable performance during continuous operation.

[0019] Through the synergistic effect of precise clamping, high-precision positioning, dust removal, and efficient cooling, the equipment can effectively reduce the roughness of the hole walls, eliminate burrs, and ensure smooth and flat hole walls. This allows for smoother airflow through accordion parts after assembly, significantly improving the purity of the instrument's tone and the stability of its pitch. The improved polishing precision also ensures the consistency of the hole dimensions of the parts, enhances the assembly compatibility of the parts with other components of the accordion's sound system, reduces the amount of adjustment work during assembly, and indirectly improves the overall production efficiency and product quality of the accordion.

[0031] As shown in the figure, specific structures and devices are labeled in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment.

Detailed Implementation

[0032] The following is a detailed description of a hole wall grinding device for processing accordion musical instrument parts provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0033] like Figures 1 to 10 As shown, an embodiment of the present invention provides a hole wall grinding device for processing accordion musical instrument parts, comprising: a mounting box 1, a slide rail 2 mounted on one side of the interior of the mounting box 1, a first hydraulic rod 3 mounted on the other side of the slide rail 2, a U-shaped seat 10 mounted on the output end of the first hydraulic rod 3, a grinding mechanism 4 mounted on the inner side of the top of the U-shaped seat 10, and cameras 8 mounted on both sides of the top of the mounting box 1. The cameras 8 are tilted and their rotation angle is adjusted in real time according to the grinding position of the grinding mechanism 4. Several LED lights 9 are provided on the outer side of each camera 8. When the grinding mechanism 4 performs grinding, the slide rail 2 drives the U-shaped seat 10 to move in the X direction, thereby driving the grinding mechanism 4. The device moves in the X direction and simultaneously drives the grinding mechanism 4 to move in the Y direction through the output end of the first hydraulic rod 3, thereby enabling the grinding mechanism 4 to perform horizontal positioning and grinding. Several LED lights 9 are fixedly connected to the inner wall of the mounting box 1. The LED lights 9 can adjust the light to facilitate adjustment according to the light intensity required by the camera 8. A clamping assembly 5 is symmetrically installed on a pair of sides of the mounting box 1. The clamping assembly 5 is used to clamp the material. A positioning assembly 6 is installed at the bottom of the U-shaped seat 10. The positioning assembly 6 is used to position the material. A cooling assembly 7 is installed inside the positioning assembly 6. The cooling assembly 7 is used to cool the grinding head and clean the dust during grinding.

[0034] like Figures 3 to 8As shown, the clamping assembly 5 includes a second hydraulic rod 501, which is installed on the inner wall of the mounting box 1. The output end of the second hydraulic rod 501 is fixedly connected to a non-shaped mounting base 502. Clamping blocks 504 are symmetrically installed at the upper and lower ends of the non-shaped mounting base 502. The clamping assembly 5 also includes a limiting rod 505, which is fixedly connected to the center of the bottom end of the upper clamping block 504. A pressure sensing mechanism 506 is embedded in the center of the top end of the lower clamping block 504. The number of limiting rods 505 and pressure sensing mechanisms 506 are the same and they correspond one-to-one. A small hole is provided at the center of the lower clamping block 504. A pressure sensor is installed inside the small hole, and a pressure spring is installed on the pressure sensor. A pressing block is installed on the pressure spring. When the upper and lower clamping blocks 504 clamp the material, the limiting rod 505 enters the small hole and squeezes the pressing block. The pressing block presses the pressure spring, causing the pressure spring to be compressed. At the same time, the pressure spring presses the pressure sensor, so that the pressure sensor can detect the squeezing force of the limiting rod 505 and avoid excessive pressure that could cause severe indentations on the surface of the material.

[0035] like Figures 3 to 5As shown, the positioning component 6 also includes a fixing base 601, which is installed on the inner side of the bottom end of the U-shaped base 10. A micro motor 602 is installed on one side of the top end of the fixing base 601. The output end of the micro motor 602 is fixedly connected to a first gear 603. When the output end of the micro motor 602 drives the first gear 603 to rotate, the output end of the micro motor 602 simultaneously drives the belt 605 to drive the transmission. At the same time, the belt 605 drives the rotating shaft 606 on one side to rotate, and the first gear 603 drives the second gear 604 to rotate. The second gear 604 drives the rotating shaft 606 on the other side to rotate in the opposite direction, thereby causing the rotation of the two rotating shafts 606 to be... Since the two suction cups 609 rotate in opposite directions, their nozzles simultaneously rotate to a horizontal position or simultaneously rotate to a vertical position to both sides. The positioning assembly 6 also includes a second gear 604, which meshes with the outer wall of one end of the first gear 603. A pair of rotating shafts 606 are symmetrically rotatably connected to the top of the fixing base 601. Suction cups 609 are fixedly connected to the center of each of the two rotating shafts 606. One rotating shaft 606 is fixedly connected to the center of the second gear 604. The positioning assembly 6 also includes a belt 605, which is connected to the outer wall of the other rotating shaft 606. The other end of the belt 605 is connected to the micro-horse. The output end of the 602 is connected by a belt. A first vacuum pump 607 is installed on the other side of the top of the fixed base 601. The outlet of the first vacuum pump 607 is connected to a flexible hose 608. The hose 608 has good flexibility and passes through the center of the two rotating shafts 606, communicating with the inner wall of the suction cup 609. This avoids significant impact on the hose 608 when the suction cup 609 rotates. Both ends of the hose 608 pass through the inner wall of the rotating shaft 606 and are connected to the suction cup 609. The micro motor 602 in the positioning assembly 6 is activated, and its output end synchronously drives the first gear 603 to rotate, which is then driven by the belt 605. On one hand, the first gear 603 drives the meshing connection... The second gear 604 rotates; on the other hand, the belt 605 drives the other side shaft 606 to rotate, which eventually causes the two shafts 606 symmetrically arranged at the top of the fixed base 601 to rotate in opposite directions, thereby driving the suction cup 609 at the center of the shaft 606 to rotate synchronously to a horizontal position (with the suction nozzle facing upward), providing a stable support surface for material placement. The accordion parts (material) to be processed are placed smoothly on the top of the two suction cups 609. The first vacuum pump 607 is started, and the negative pressure generated by it is transmitted to the suction cup 609 through the hose 608 (penetrating the inner wall of the shaft 606), so that the suction cup 609 firmly adheres to the bottom of the material, completing the initial positioning of the material and preventing the material from shifting during the subsequent clamping process.

[0036] like Figures 6 to 10As shown, the cooling assembly 7 includes a cooling cavity 701, which is located at the center of the fixed base 601. The cooling cavity 701 contains several V-shaped seats 703. Several thermally conductive silicone rubbers 704 are fixedly connected to the outer wall of one end of each V-shaped seat 703. The V-shaped seats 703 are designed to fit the size of the grinding head, and the thermally conductive silicone rubbers 704 on the inner side of the V-shaped seats 703 facilitate heat transfer to the V-shaped seats 703. The cooling assembly 7 also includes several springs 705, each with a mounting bracket inside. A heat-conducting telescopic sleeve transfers heat from the V-shaped seat 703 to the inner wall of the cooling chamber 701. Cooling oil inside the spiral cooling holes 707 then cools the inner wall of the cooling chamber 701. Several springs 705 are fixedly connected to the other end of the V-shaped seat 703, and the other ends of the springs 705 are also fixedly connected to the inner wall of the cooling chamber 701. Spiral cooling holes 707 are provided on the outer wall of the top of the cooling chamber 701. A circulation pump 706 is installed on one side of the bottom of the fixed seat 601. The outlet of the 6 is connected to the spiral cooling hole 707 through a pipe. The second vacuum pump 711 is started, which is connected to the collection frame 710 through a pipe, creating a negative pressure in the cooling chamber 701 (located at the center of the fixed base 601). Metal dust or resin dust generated during the grinding process is drawn into the cooling chamber 701 by the negative pressure. The dust enters the collection frame 710 with the airflow. The dust filter inside the collection frame 710 firmly captures the dust. The filtered clean airflow is discharged through the second vacuum pump 711, preventing the dust from scratching the smooth holes that have been ground. The wall prevents dust from entering the equipment and contaminating the transmission components. During continuous grinding, the grinding head gradually moves into the cooling chamber 701. The outer wall of the grinding head presses against several V-shaped seats 703 inside the cooling chamber 701. The spring 705 at the other end of the V-shaped seat 703 contracts and deforms, so that the thermally conductive silicone 704 on the outer wall of one end of the V-shaped seat 703 fits tightly against the surface of the grinding head, quickly conducting the heat generated by the grinding head. The heat is transferred through the V-shaped seat 703 to the thermally conductive expansion sleeve inside the spring 705, and then to the inner wall of the cooling chamber 701.

[0037] like Figures 6 to 8As shown, the cooling assembly 7 also includes an oil chamber 709, which is located on the inner wall of the middle part of the fixed base 601. The interior of the oil chamber 709 is connected to the inlet of the circulating pump 706. The other end of the spiral cooling hole 707 is connected to an outlet pipe 708, which is connected to the oil chamber 709. After the cooling oil inside the spiral cooling hole 707 has finished cooling, the cooling oil re-enters the oil chamber 709 through the outlet pipe 708, thus realizing oil circulation. The cooling assembly 7 also includes several cooling fans 702. A heat-conducting ring is installed on the bottom outer wall of the mounting base 601, between it and the bottom outer wall of the mounting base 601 for the cooling fan 702. This facilitates the transfer of heat from the oil chamber 709 to the heat-conducting ring, which is then cooled by the cooling fan 702. A collection frame 710 is installed on the bottom inner wall of the mounting base 601. Several small holes are opened through the inner wall of the collection frame 710 to facilitate airflow. A dust filter is installed inside the collection frame 710 to adsorb dust and prevent it from entering the second vacuum pump 711. Vacuum pump 711 causes damage. Collection frame 710 is connected to cooling chamber 701. A second vacuum pump 711 is installed on the other side of the bottom of fixed base 601. The outlet of the second vacuum pump 711 is connected to collection frame 710. A flexible cover 712 is fixedly connected to the outer wall of the top of fixed base 601. The flexible cover 712 has good flexibility and is easy to contact the bottom of the material, thereby realizing a small sealed space. The circulation pump 706 on one side of the bottom of fixed base 601 is started, and its inlet draws cooling oil from oil chamber 709 on the inner wall of the middle part of fixed base 601. Cooling oil is injected into the spiral cooling hole 707 on the outer wall of the top of the cooling chamber 701 through the outlet. The cooling oil flows at high speed in the spiral cooling hole 707 and exchanges heat efficiently with the inner wall of the cooling chamber 701. After absorbing heat, the cooling oil flows back to the oil chamber 709 through the outlet pipe 708, forming a cooling oil circulation. At the same time, the heat dissipation fan 702 on the outer wall of the bottom of the fixed seat 601 is started. The residual heat in the oil chamber 709 is quickly dissipated into the air through the heat conduction ring at the bottom of the fixed seat 601, ensuring that the grinding head is always in a normal working state and avoiding thermal expansion or deformation.

[0038] The working principle of the technical solution provided by this invention is as follows: Positioning preparation: Start the micro motor 602, whose output end drives the first gear 603 to rotate, which in turn drives the meshing second gear 604 to rotate. At the same time, the micro motor 602 drives the two rotating shafts 606 to rotate in opposite directions through the belt 605, which finally drives the two suction cups 609 to rotate synchronously to the horizontal position (suction nozzle facing upward). Place the material to be processed on the top of the suction cup 609, start the first vacuum pump 607, and supply air to the suction cup 609 through the hose 608 so that the suction cup 609 can adsorb and fix the material, completing the initial positioning.

[0039] Material clamping: The second hydraulic rod 501 is activated, and its output end pushes the irregular mounting base 502 to move towards the material, causing the clamping block 504 to approach the two sides of the material. The cylinder 503 drives the clamping block 504 to move further until the upper and lower clamping blocks 504 are in contact with the material. At this time, the limiting rod 505 of the upper clamping block 504 is inserted into the small hole of the lower clamping block 504, squeezing the pressing block and the pressure spring. The pressure sensor detects the squeezing force in real time to avoid excessive pressure causing material indentation. Then, the cylinder 503 drives the clamping block 504 to move slightly upward, and the micro motor 602 rotates in the opposite direction to rotate the suction cup 609 90 degrees (the suction nozzle is horizontal). The cylinder 503 drives the clamping block 504 to reset, and the bottom of the material is in contact with the arc surface of the suction cup 609 for support, completing stable clamping.

[0040] Grinding Positioning and Operation: Turn on camera 8 and LED light 9. LED light 9 adjusts the light intensity to provide a clear field of view for camera 8. Camera 8 monitors the grinding position in real time and assists in adjusting the angle. Drive U-shaped seat 10 to move along the X direction through slide rail 2. First hydraulic rod 3 drives grinding mechanism 4 to move along the Y direction to achieve precise positioning of grinding mechanism 4 in the horizontal direction. Then start grinding mechanism 4 to perform grinding operation on the material hole wall.

[0041] Dust removal: When the grinding head of the grinding mechanism 4 is inserted into the hole wall of the material, the second vacuum pump 711 is started. The flexible cover 712 fits against the bottom of the material to form a small sealed space. Negative pressure suction is generated in the cooling chamber 701, which sucks the dust generated by grinding into the cooling chamber 701. Then the dust is guided into the collection frame 710 through the cooling chamber 701. The dust filter in the collection frame 710 adsorbs the dust and prevents the dust from entering the second vacuum pump 711 and causing damage.

[0042] Grinding head cooling: The grinding head continues to move downwards into the cooling chamber 701, squeezing the V-shaped seat 703. The spring 705 contracts, causing the V-shaped seat 703 to fit against the grinding head. The heat-conducting silicone 704 on its inner side conducts the heat from the grinding head to the V-shaped seat 703, and then transfers it to the inner wall of the cooling chamber 701 through the heat-conducting expansion sleeve inside the spring 705. The circulation pump 706 is started to draw cooling oil from the oil chamber 709 and inject it into the spiral cooling hole 707 through the pipe. The cooling oil flows in the spiral cooling hole 707 and absorbs the heat from the inner wall of the cooling chamber 701, thus cooling the grinding head. The cooled oil after heat exchange flows back to the oil chamber 709 through the liquid outlet pipe 708, completing the oil circulation. At the same time, the cooling fan 702 is started to remove the heat from the oil chamber 709 through the heat-conducting ring at the bottom of the fixed seat 601. The cooling fan 702 accelerates heat dissipation and ensures the cooling effect.

[0043] Operation completed: After the grinding operation is completed, the grinding mechanism 4, circulation pump 706, second vacuum pump 711, and cooling fan 702 are turned off in sequence; cylinder 503 drives clamping block 504 to release the material, and second hydraulic rod 501 drives irregular mounting seat 502 to reset; first vacuum pump 607 is turned off, suction cup 609 releases the material, the processed parts are taken out, and the equipment is reset to wait for the next operation.

[0044] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
