Description

Technical Field

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

[0002] As a precision keyboard instrument, the accordion requires multiple precision holes in its core components, such as the bass plate, reed seats, and key guides, during the manufacturing process. For example, the bass plate needs to have multiple holes arranged in an array, with a diameter typically between 1 and 5 mm. During the manufacturing process, after these holes are formed through drilling, boring, and other processes, microburrs, chip residue, and machining textures inevitably appear on the inner walls. These defects directly affect the assembly precision of the components, causing key jamming, poor reed vibration, and in severe cases, abnormal touch and distorted sound quality during performance. Therefore, the holes in these components usually require grinding and polishing during the manufacturing process. For accessories such as bass plates with multiple micro-holes, conventional rigid grinding heads, honing tools, and small polishing instruments are difficult to penetrate into the fine holes and cannot achieve simultaneous processing of multiple holes, resulting in extremely poor adaptability. Therefore, the market now generally uses abrasive flow polishing machines that can simultaneously grind multiple micro-holes. These machines use high pressure to drive the flow of fluid abrasive, allowing the abrasive medium to penetrate through each channel inside the workpiece. They rely on the friction of the abrasive grains to remove burrs and processing marks from the hole walls. They are suitable for grinding narrow, deep holes and array-type multi-hole grinding conditions, and have become the mainstream equipment for hole wall processing of such accessories at present. However, existing abrasive flow polishing machines mostly use a unidirectional flow, single-sided grinding method when grinding the holes in bass plates. This type of processing method is prone to over-grinding at the hole ends and insufficient grinding at the ends, reducing the uniformity of the overall grinding of a single hole. To address this issue, we propose a hole wall grinding device for accordion instrument parts processing. Summary of the Invention

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figures 1-16 A hole wall grinding device for processing accordion musical instrument parts includes a main body 1 and a plate 9 (such as the bass plate body of an accordion part). A fixing plate 2 is fixedly installed on the inner wall of the main body 1. A servo motor 3 is fixedly installed on the fixing plate 2. A rotating shaft is fixedly installed on the drive end of the servo motor 3. A turntable 4 is fixedly installed on the rotating shaft. A first feeding box 5 is fixedly installed on the turntable 4. A second feeding box 6 is fixedly installed on the turntable 4 (both the first feeding box 5 and the second feeding box 6 have micro-holes for ventilation). A feeding component 7 is installed on the turntable 4. A material equalization component 8 is fixedly installed between the first feeding box 5 and the second feeding box 6.

[0018] The feeding assembly 7 includes a first rack 73 that is sealed and slidably installed on the first feeding box 5 and the second feeding box 6 respectively. A partition 74 is fixedly installed on one end of each of the two first racks 73, and the two partitions 74 are sealed and slidably installed in the first feeding box 5 and the second feeding box 6 respectively. A drive mechanism is installed on the turntable 4.

[0019] The drive mechanism includes an arc-shaped rack 76 fixedly mounted on the fixed plate 2, two rotating shafts 77 running through and rotatably mounted on the turntable 4, each of the two rotating shafts 77 having an incomplete gear 78 that meshes with the arc-shaped rack 76, and each of the two rotating shafts 77 having an incomplete gear 79 fixedly mounted, and each of the two incomplete gears 79 meshing with the corresponding first rack 73, and a material conveying component mounted on the material conveying box 5.

[0020] The material conveying component includes a conveying pipe 72 that is sealed through and fixedly installed on the material conveying box 5. A baffle 75 is fixedly installed on the upper partition 74. The baffle 75 has a square opening that matches the corresponding conveying pipe 72 (shown in the figure but not standardized, depending on the context). Figure 7(As shown in the direction), a feeding cylinder 71 is fixedly installed on the top wall inside the main body 1 of the equipment.

[0021] When it is necessary to use this equipment to grind the holes on the bass plate (i.e., plate 9) of an accordion accessory, first open the door on the main body 1 of the equipment (combined with...). Figure 1 As can be seen, the plate 9 is then placed between the first conveyor box 5 and the second conveyor box 6. At this point, the cooperation of the first conveyor box 5 and the second conveyor box 6 achieves clamping and fixing of the plate 9, as well as sealing of its upper and lower surfaces. This facilitates subsequent grinding of the multiple holes on the plate 9 by the feeding assembly 7 and the equalizing assembly 8. Protective pads are also fixedly installed on the sides of the first conveyor box 5 and the second conveyor box 6 that are close to each other (in conjunction with...). Figure 6 As can be seen, both protective pads are made of high-elasticity polyurethane, wear-resistant silicone and other materials. These materials have excellent anti-slip and anti-friction properties, which can effectively improve the stability of the material feeding box 1 5 and material feeding box 2 6 in clamping and fixing the plate 9. At the same time, the buffering and protective effect of the protective pads can also prevent the material feeding box 1 5 and material feeding box 2 6 from excessively squeezing the plate 9 and causing local deformation of the plate 9.

[0022] After the sealing plate 9 is installed between the first conveyor box 5 and the second conveyor box 6, the servo motor 3 is started. At this time, the operation of the servo motor 3 will drive the first conveyor box 5 and the second conveyor box 6 to rotate clockwise (along the axis) through the cooperation of the rotating shaft and the turntable 4. Figure 6 (as shown in the direction), until the feed end of the feed pipe 72 (along... Figure 6 As shown, the left end of the conveying pipe 72 is the feed end, and its right end is the discharge end. The conduit connecting the conduit to the lower end of the feeding cylinder 71 (from...) Figure 6 As can be seen, a guide tube is fixedly connected to the lower end of the feeding cylinder 71, and an electric valve is installed on the guide tube. These are directly opposite each other, and during the clockwise rotation of the feed box 5 driven by the turntable 4, the corresponding first rack 73, rotating shaft 77, and incomplete gear 78 on the feed box 5, through the engagement of the arc-shaped rack 76 with the corresponding incomplete gear 78, rotating shaft 77, and incomplete gear 79, the driving force applied to the corresponding first rack 73 can drive the first rack 73 and the corresponding partition 74 and baffle 75 to move downwards (along...). Figure 7 (in the direction shown), until the square opening on the baffle 75 is directly opposite the discharge end of the conveying pipe 72.

[0023] When the feed end of the feed pipe 72 is directly opposite to the conduit connected to the lower end of the feed cylinder 71, and the discharge end is directly opposite to the square opening on the baffle 75, the electric valve on the conduit connected to the lower end of the feed cylinder 71 is activated to output the abrasive flow medium (hereinafter referred to as the medium) inside the feed cylinder 71. Through the cooperation of the conduit and the feed pipe 72, the medium is input into the feed box 5. After the medium fills the gap between the upper surface of the plate 9 and the partition 74 located inside the feed box 5, the electric valve is closed.

[0024] After a suitable amount of medium is injected into the first feeding box 5, the servo motor 3 is started in reverse. At this time, the operation of the servo motor 3 will drive the first feeding box 5 and the second feeding box 6 to rotate and reset in opposite directions through the cooperation of the rotating shaft and the turntable 4. During this process, the driving force applied to the corresponding first rack 73 by the arc rack 76 and the corresponding incomplete gear 78, and the rotating shaft 77 and the incomplete gear 79 can drive the partition 74 and the baffle 75 inside the first feeding box 5 to move upward continuously (along the direction of rotation). Figure 7 (as shown in the direction), until the upper surface of the partition 74 is in contact with the inner top wall of the conveyor box 5 (as shown in the direction). Figure 6 (As shown in the diagram), the baffle 75 completely blocks the discharge end of the conveying pipe 72, which can effectively avoid the risk of the medium flowing out in reverse from the discharge end of the conveying pipe 72 during the subsequent process of the medium flowing through the conveying box 5 by gas compression.

[0025] Reference Figures 1-16 The material equalization component 8 includes two elastic membranes 811 that are respectively fixedly installed in the first material conveying box 5 and the second material conveying box 6. A stirring tube 812 is sealed and fixedly installed between the two elastic membranes 811. A gas conveying mechanism is installed between the first material conveying box 5 and the second material conveying box 6.

[0026] The gas delivery mechanism includes an integrated air extraction and refrigeration unit 10 fixedly mounted on a fixed plate 2. The integrated air extraction and refrigeration unit 10 is fixedly connected to two air supply pipes 86 (shown in the figure but not labeled, in conjunction with...). Figure 16 As can be seen, both conveyor boxes 5 and 6 are provided with air-gathering slots 81, and both conveyor boxes 5 and 6 are sealed and fixedly installed with air supply pipes 86. The air inlet ends of the two air supply pipes 86 (along...) Figure 11 As shown, the upper left end of the air duct 86 is set as the air inlet. Both are matched with the integrated air extraction and refrigeration unit 10. Both the first conveying box 5 and the second conveying box 6 have two air ducts 82, and the air ducts 82 are connected to the corresponding air gathering ducts 81. Both the first conveying box 5 and the second conveying box 6 have grooves 83 that are connected to the two corresponding air ducts 82. Adjustment components are installed on both air gathering ducts 81, and force transmission components are installed on both grooves 83.

[0027] Both adjusting components include a rotating rod 84, which is rotatably mounted on the corresponding wind-gathering slot 81. A wind wheel 85 is fixedly mounted on both rotating rods 84, and spring telescopic rods 89 evenly distributed in a ring are fixedly mounted on both rotating rods 84. A wind deflector 810 is fixedly mounted on each spring telescopic rod 89.

[0028] Both power transmission components include a reciprocating lead screw 87, which is fixedly mounted on the corresponding rotating rod 84. Both reciprocating lead screws 87 are equipped with sliders 88 via ball nuts, and both sliders 88 are rotatably connected to the corresponding stirring tubes 812. Both sliders 88 are sealed and slidably mounted on the corresponding grooves 83. Both grooves 83 are fixedly mounted with second racks 814, and both stirring tubes 812 are fixedly mounted with rotating gears 813 that mesh with the corresponding second racks 814.

[0029] Both stirring tubes 812 are provided with air vents 816 that are evenly distributed in a ring, and both material feeding boxes 5 and 6 are provided with air injection ports 817.

[0030] Both stirring tubes 812 have convex plates fixedly installed on their inner walls, and both stirring tubes 812 have multiple striking rollers 815 rolled inside them.

[0031] When the medium is input into the conveying box 5 and it is rotated and reset under force (at this time, the air supply pipe 86 on the conveying box 5 is directly opposite the air supply pipe), the integrated vacuum cooling unit 10 is started (the integrated vacuum cooling unit 10 is an existing conventional device, and its specific working principle and internal components are conventional settings, which will not be further described here). The operation of the integrated vacuum cooling unit 10 will first draw gas into the gas pump outside the main body 1, convert it into cooling inside the machine, and finally output it through the air supply pipe. When the cooled gas enters the air gathering groove 81 opened on the conveying box 5 along the pipe wall of the air supply pipe and the corresponding air supply pipe 86, since the end of the air supply pipe 86 is connected to the corresponding air gathering groove 81 and is opposite to the inclined fan blade on the corresponding impeller 85, the driving force generated by the gas inside the corresponding air gathering groove 81 along the air supply pipe 86 on the fan blade on the corresponding impeller 85 can rotate the impeller 85.

[0032] As the flowing gas propels the impeller 85 to rotate continuously, the gas flows with the impeller 85 to the point where the air delivery trough 82 connects to the air gathering trough 81. There, the gas continues to flow to the left along the wall of the air delivery trough 82. Figure 9(As shown in the direction), after the gas enters the corresponding groove 83 along the wall of the air conveying channel 82, the gas will continue to enter the material conveying box 5 along the connecting passage between the slider 88, the stirring pipe 812, the exhaust port 816 and the air injection port 817. As the gas volume between the medium inside the material conveying box 5 and the corresponding partition 74 gradually increases, the gas exerts a compressive force on this part of the medium. When this force exceeds the flow resistance of the medium, the gas can compress the medium inside the material conveying box 5 and the upper surface of the plate 9, causing it to flow downwards (along the direction shown in ... Figure 6 (As shown in the direction), the grinding process is achieved by passing through multiple holes opened on the plate 9 from top to bottom, thereby enabling the equipment to perform grinding on the holes on the plate 9.

[0033] The flowing gas pushes the medium inside the feed box 5 to flow continuously downwards (along... Figure 6 (As shown in the direction), the medium originally collected inside the first conveyor box 5 will gradually collect in the second conveyor box 6 under its own gravity. After the initial grinding of the holes on the plate 9 is completed and most of the medium inside the first conveyor box 5 has flowed into the second conveyor box 6, the servo motor 3 is started. At this time, the operation of the servo motor 3 will drive the first conveyor box 5 and the second conveyor box 6 to rotate clockwise until the second conveyor box 6 rotates to the top of the first conveyor box 5. Then, through the cooperation of the material equalization component 8 and the vacuum cooling integrated machine 10, the medium inside the second conveyor box 6 can be squeezed downward, so that it flows downward from the top end of the hole on the plate 9 (the bottom end of the original hole), thereby achieving the grinding of both ends of the hole on the plate 9. This helps to improve the uniformity of the grinding of both ends of the hole on the plate 9 and improve the grinding effect of the equipment on the hole on the plate 9.

[0034] Simultaneously, when the flowing gas drives the impeller 85 to rotate, the impeller 85, in conjunction with the corresponding rotating rod 84, reciprocating screw 87, ball nut, and slider 88, generates a driving force on the corresponding stirring tube 812, which can drive the stirring tube 812 to move horizontally back and forth (along the direction of rotation). Figure 11 (as shown in the direction), and during this process, by rotating the gear 813 and engaging the second rack 812, the driving force applied to the stirring tube 812 allows the stirring tube 812 to move back and forth while rotating around its own axis to uniformly stir the abrasive flow inside the feed box 5. This helps to improve the uniformity of the medium distributed inside the feed box 5 and on the upper surface of the plate 9, that is, to improve the consistency of the gas extrusion medium flow in grinding the holes on the plate 9, and to improve the air grinding effect of the equipment on the holes on the plate 9. At the same time, the forced shearing and tumbling of the medium by the rotation and reciprocating of the stirring tube 812 helps to break the relative static state between the abrasive particles and the carrier, causing the abrasive particles that have settled at the bottom to be resuspended, so that the solid particles are macroscopically uniformly distributed in the medium, avoiding fluctuations in grinding ability caused by concentration differences.

[0035] Simultaneously, during the mixing and stirring of the medium by the rotation of the stirring tube 812, the corresponding multiple striking rollers 815 will rotate together. When the striking rollers 815 rotate with the corresponding stirring tube 812 to their upper or lower ends (along the direction of rotation), the stirring rollers 815 will rotate. Figure 14 (As shown in the direction), the striking roller 815 will accelerate under its own gravity and impact the wall of the corresponding stirring tube 812. The vibration generated by the impact on the wall of the stirring tube 812 is transmitted to the medium. First, it can break up the soft agglomerates of abrasive particles, making the solid particles more evenly distributed and avoiding fluctuations in grinding ability caused by local concentration differences. This helps to further improve the uniformity of grinding multiple holes on the plate 9.

[0036] Furthermore, when the medium passes through the holes on the plate 9 under the propulsion of gas, continuous friction and shearing occur between the abrasive grains and the hole wall, and between the medium and the inner wall of the channel, releasing significant grinding heat. This heat causes the medium temperature to rise rapidly. The rheological properties of the medium are extremely sensitive to temperature. The increase in temperature will cause the viscosity of the polymer carrier to decrease significantly, thereby changing the shear stress, grinding ability and flow behavior of the medium. In addition, local overheating may exacerbate the adhesion of the medium to the holes on the plate 9, increasing the difficulty of hole blockage and cleaning. Moreover, since the plate 9 is made of metal, when the medium flows and grinds the hole wall on the plate 9, its own temperature continues to rise. The medium transfers this heat to the plate 9, causing local thermal warping or residual stress in the plate 9, reducing the overall flatness and dimensional accuracy of the plate 9.

[0037] To this end, the walls of the two stirring tubes 812 are made of thermally conductive material. When the cooling gas flows continuously along the connection passage between the groove, the slider 88, the stirring tube 812 and the air injection port 817, the cooling can be absorbed and carried away by the heat of the medium through the walls of the stirring tube 812. At the same time, the reciprocating movement and rotation of the stirring tube 812 can effectively improve the uniformity of the overall cooling of the medium by the equipment, and further ensure the uniformity of the grinding of all the perforated bodies on the plate 9 by the medium.

[0038] Meanwhile, the viscosity of the medium can change dynamically due to factors such as batch differences in formulation, fluctuations in operating temperature, abrasive particle sedimentation and stratification, and viscosity decay during use. The polishing of the hole walls of the accordion bass plate has strict requirements on the flow stability and thrust matching of the medium. If the equipment does not use a constant medium flow driving force according to the medium viscosity, it is easy to reduce the final grinding effect of the equipment on the bass plate. For example, when the medium viscosity is too low and the constant medium flow driving force is greater than the required force, it is easy to over-grind the holes on the bass plate, and vice versa.

[0039] When the stirring tube 812 is driven to rotate by the airflow to stir the medium inside the feed box 5, the viscosity of the medium will directly affect the motion resistance of the stirring tube 812, thereby changing the operating state of the transmission mechanism composed of the impeller 85, the rotating rod 84, the reciprocating screw 89, and the slider 88. For example, when the viscosity of the medium is low, the motion resistance of the stirring tube 812 decreases accordingly, and the driving force required by the impeller 85 and the rotating rod 84 in conjunction with the reciprocating screw 89 and the slider 88 to drive the stirring tube 812 will decrease synchronously. Since the integrated air extraction and refrigeration unit 10 adopts constant power operation, that is, the gas flow rate entering the air collection trough 81 is the same per unit time, when the driving force required by the impeller 85 decreases, the rotation speed of the gas-driven impeller 85 and the rotating rod 84 will gradually increase.

[0040] When the rotational speed of the rotating rod 84 increases to the point that the centrifugal force generated by its rotation is greater than the restoring force of the multiple spring telescopic rods 89 (under normal conditions, the spring telescopic rods 89 are kept in a contracted state by their own elastic force, and the wind deflectors 810 do not block the left end of the corresponding air ducts 82), along... Figure 9 (As shown in the direction), the telescopic end of the spring telescopic rod 89 will extend outward against the elastic force, and drive the baffle plate 810 fixed at the end to expand outward in sync, gradually blocking the left end of the corresponding air conveying channel 82, that is, gradually reducing the effective cross-section of the flow channel of the flowing gas into the conveying box 5. During this process, the power consumption of the gas-driven impeller 85, the rotating rod 84 and the power to overcome the throttling resistance will increase significantly, and the effective gas flow rate and pressure acting on the medium will decrease accordingly. This achieves the effect of automatically reducing the driving thrust according to the low viscosity of the medium, avoiding excessive rounding of the beam plate orifice, excessive polishing of the inner wall or geometric deviation caused by the medium flowing too fast and the impact too large, thus ensuring the processing accuracy and consistency of the hole wall.

[0041] Conversely, when the viscosity of the medium increases, the motion resistance of the stirring tube 812 increases significantly, and the resistance of the impeller 85 driving the rotating rod 84 to rotate also increases. At this time, under constant power air supply conditions, the rotation speed of the rotating rod 84 will gradually decrease. When the rotation speed decreases to the point where the centrifugal force it generates is less than the reset elastic force of the spring telescopic rod 89, the spring telescopic rod 89 retracts inward under its own elastic force, causing the baffle plate 810 to release the blockage on the left end of the air conveying channel 82. The effective flow section of the air conveying channel 82 returns to the fully open state, and the gas can smoothly enter the interior of the conveying box 5. The thrust acting on the medium increases accordingly, which ensures that the high viscosity medium can obtain sufficient driving force and smoothly pass through the holes on the plate 9, ensuring the grinding effect of the medium on its holes. This helps to further improve the equipment's ability to adaptively adjust the medium flow driving force according to the medium viscosity and ensure the grinding accuracy of the medium on the holes on the plate 9.

[0042] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0043] In this invention, when the equipment is needed to grind the plate 9, the plate 9 is first placed between the first feeding box 5 and the second feeding box 6, and then the servo motor 3 is started. At this time, the operation of the servo motor 3, in cooperation with the feeding component 7, inputs an appropriate amount of medium into the first feeding box 5. Then, through the cooperation of the vacuum cooling integrated machine 10 and the material equalization component 8, the medium inside the first feeding box 5 is driven to flow downward, flowing downward from the upper end of the hole in the plate 9 (along...). Figure 6 (As shown in the direction), unidirectional grinding of the holes on plate 9 can be achieved. After the unidirectional grinding of the holes on plate 9 is completed, the medium inside the original feed box 5 flows into the feed box 6 under the action of gravity. Then, the servo motor 3 is started. At this time, the operation of the servo motor 3 will rotate the feed box 6 to the upper end. Then, through the cooperation of the vacuum cooling integrated machine 10 and the material equalization component 8, the medium inside the feed box 6 can be squeezed to flow downwards from the upper end (the lower end of the original hole) of the hole on plate 9, thereby achieving grinding of both ends of the hole on plate 9. This can help improve the uniformity of grinding of the holes on plate 9 and improve the grinding effect of the equipment on the holes on plate 9.

[0044] Simultaneously, when the equipment, through the cooperation of the integrated air extraction and cooling unit 10 and the material equalization component 8, promotes the flow of the medium and grinds the holes on the plate 9, the cooperation of the air supply mechanism and the force supply component can drive the stirring tube 812 to move back and forth while rotating to uniformly stir the medium inside the first material box 5 or the second material box 6. This can effectively improve the uniformity of the grinding of the overall holes on the plate 9 by the equipment through the material equalization component 8. Furthermore, through the cooperation of the stirring tube and the adjustment component, the viscosity of the medium can be automatically detected, and the driving force of the equipment to squeeze the flow of the medium can be adaptively adjusted according to the detection results. This can help improve the accuracy of the equipment in grinding the holes on the plate 9 and further improve the grinding effect of the equipment in grinding the holes on the plate 9.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
