Description

A petal-shaped elastic polishing wheel structure Technical Field

[0001] This invention relates to the field of elastic polishing wheel technology, specifically a petal-shaped elastic polishing wheel structure. Background Technology

[0002] A petal-shaped elastic polishing wheel is a polishing tool composed of many independent elastic cloth pieces (or sandpaper pieces) stacked radially. Before the polishing operation begins, the CNC system or corresponding mechanical mechanism will drive the polishing wheel spindle to move along a preset trajectory, so that it actively reaches the contact position set with the workpiece surface. In batch processing that emphasizes efficiency, since both the workpiece and the polishing head adopt the same batch specifications, the diameter of the polishing wheel and the processing surface of the workpiece are fixed.

[0003] The petal-shaped flexible polishing wheel has an independent petal-like structure on its side. This design allows each "petal" to bend independently during rotation. This unique structure gives it excellent flexibility and chip removal and heat dissipation capabilities, enabling it to closely conform to the irregular curved surfaces of the workpiece for polishing and grinding. At the same time, it effectively reduces clogging and burn marks, making it particularly suitable for surface finishing and mirror treatment of materials such as metal and wood. It combines the cutting force of rigid abrasives with the adaptability of flexible tools, making it a common choice in precision polishing. However, precisely because of its flexible structure, the petal-shaped polishing wheel wears significantly during processing. With continuous use, its diameter gradually and irreversibly decreases, leading to a decrease in working line speed. The contact pressure and contact area with the workpiece also change accordingly. This not only causes a gradual decrease in material removal rate, making it difficult to maintain the consistency of the polishing process, but also interrupts production due to the need for frequent replacement or overhaul of the polishing head, thus significantly affecting the efficiency and cost control of automated production.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing petal-shaped elastic polishing wheel structure. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a petal-shaped elastic polishing wheel structure to solve the problem mentioned in the background art. While the elastic design of the petal-shaped elastic polishing head allows it to deform and closely adhere to the workpiece for polishing, its elastic design results in low wear resistance. After continuous use, its diameter gradually and irreversibly decreases, and the contact pressure and contact area with the workpiece also change accordingly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a petal-shaped elastic polishing wheel structure, comprising a polishing machine and a clamping device mounted on the polishing machine, further comprising: a polishing wheel body for polishing workpieces, which is limited and disposed in the clamping device; a push pin that is elastically inserted in the polishing wheel body to sense its wear; a deformation plate that is coaxially and symmetrically disposed on the inner wall of the polishing wheel body for elastic expansion; an adjusting rod that is movably inserted in the deformation plate to drive its elastic deformation; a limiting component that is sleeved on the surface of the adjusting rod for positioning its movement, and the limiting component includes irregularly shaped blocks that are fixedly sleeved on the surface of the adjusting rod at equal intervals; a moving column that is symmetrically disposed on the surface of the irregularly shaped blocks and moves elastically with their displacement; and a first hydraulic column and a second hydraulic column fixed on one side of the push pin for compensating its displacement.

[0007] Preferably, a clamping device is provided on one side of the polishing machine, and meshing gears are symmetrically arranged in the clamping device, and the surface of the gears is provided with an arc-shaped outer shell; a circular cylinder is rotatably sleeved on the top of the clamping device, and the circular cylinder is fixed on the arc-shaped outer shell; a motor is installed at one end of the polishing machine, and gears are fixedly sleeved on the output end of the motor and the surface of the clamping device, respectively.

[0008] Preferably, a connecting column is fixed on one side of the polishing machine, and a pin is elastically limited on the inner wall of the connecting column. One side of the pin contacts the bottom end of the adjusting rod, and the length of the bottom end of the pin is longer than the bottom end of the polishing wheel body. An adjusting rod is movably sleeved on the surface of the pin, and one side of the adjusting rod contacts one side of the deformation plate. The length of the bottom end of the adjusting rod is slightly lower than the bottom end of the polishing wheel body.

[0009] Preferably, a support plate is provided in the hollow part of the inner wall of the polishing wheel body, and the support plate is in contact with the inner wall of the polishing wheel body; the support plate is composed of two parts: a disc-shaped plate and a rod, and the rod is evenly distributed at the bottom end of the support plate.

[0010] Preferably, the polishing wheel body consists of two parts: a polishing shank and a polishing head. The polishing head is elastically connected to one side of the polishing shank. The top end of the polishing shank is clamped and connected to a clamping device. The polishing heads are independently arranged at equal angles, and the surfaces of every two sets of polishing heads are provided with equal angles.

[0011] Preferably, the top of the clamping device is fixed with a protective shell, and movable columns are symmetrically inserted into the protective shell; a pin and an adjusting rod are also movably inserted into the protective shell.

[0012] Preferably, a first hydraulic column and a second hydraulic column are fixed on one side of the clamping device, and the first hydraulic column and the second hydraulic column are connected to each other; the first hydraulic column and the second hydraulic column are respectively composed of a reservoir pipe, a piston rod and a return spring, and oil is provided in the first hydraulic column and the second hydraulic column.

[0013] Preferably, the movable column consists of a triangular prism and a sliding rod. The triangular prism is movably inserted into the surface of the adjusting rod, and the surface of the adjusting rod is provided with corresponding grooves at equal intervals. One side of the sliding rod is fixed to the triangular prism, and the other side of the sliding rod passes through the protective shell and is movably inserted into it. A compression spring is elastically sleeved on the surface of the sliding rod, and the two sides of the compression spring are fixed to the inner wall of the protective shell and one side of the triangular prism, respectively.

[0014] Preferably, the deformation plates are arranged in a mirror symmetrical manner, and the surface of the deformation plates is inclined; an arc-shaped groove is opened through the surface of the deformation plates at equal angles, and a support plate is movably inserted in the arc-shaped groove.

[0015] Preferably, the irregularly shaped card block is trapezoidal, and the irregularly shaped card block is coaxially and movably connected to the protective shell; the surface curvature of the irregularly shaped card block is adapted to one side of the moving column, and a moving column is movably inserted between every two sets of the irregularly shaped card blocks.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention ingeniously utilizes the independent hollow shape of the elastic petal polishing head and its elastic deformation during processing, as well as the characteristic that the elastic material gradually wears down and is irreversible. By combining the distance of the ejector pin retracting during processing with the unidirectional limiting structure, it can automatically and in real time compensate for the gap caused by the wear of the polishing head, ensuring that its working surface always maintains the preset contact pressure with the workpiece. This fundamentally avoids problems such as uneven polishing and decreased precision caused by polishing head wear, ensuring the long-term stability of the processing effect, extending the effective service life of a single polishing head, and directly reducing the frequency and cost of consumable replacement. At the same time, the stable compensation structure reduces the downtime caused by adjusting or replacing the polishing head, achieving more continuous and efficient production.

[0030] 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.

[0031] Please refer to Figures 1 to 13. The present invention provides a technical solution: a petal-shaped elastic polishing wheel structure, including a polishing machine 1 and a clamping device 3 mounted on the polishing machine 1, and further including: a polishing wheel body 2 for polishing workpieces, which is limited and disposed in the clamping device 3; a push pin 5 elastically inserted in the polishing wheel body 2 to sense its wear; a deformation plate 9 coaxially and symmetrically disposed on the inner wall of the polishing wheel body 2 for elastic expansion; an adjusting rod 8 movably inserted in the deformation plate 9 to drive its elastic deformation; a limiting component sleeved on the surface of the adjusting rod 8 for positioning its movement, and the limiting component includes irregularly shaped blocks 11 fixedly sleeved on the surface of the adjusting rod 8 at equal intervals; a moving column 12 symmetrically disposed on the surface of the irregularly shaped blocks 11 that elastically moves with its displacement; and a first hydraulic column 6 and a second hydraulic column 14 fixed on one side of the push pin 5 for compensating its displacement.

[0032] Additionally, it should be noted that the clamping device 3 is coupled to the polishing handle 21. The clamping device 3 includes a coupling interface and a clamping mechanism (such as a clamping rod, a steel ball lock, and a spring). The polishing handle 21 is aligned and inserted into the drive unit interface. The clamping rod, loaded by the spring, presses down, driving the internal steel ball to move and engage with the annular groove at the top of the polishing handle 21, thus achieving clamping and axial fixation. The polishing wheel body 2, the clamping device 3, and the top of the connecting column 4 are all connected to a moving mechanism, which is equipped with a sensing system. If the preset distance is reached without sensing pressure, it will continue to move forward until it senses the pressure of the polishing wheel body 2 contacting the workpiece. Workpieces of the same specification and the polishing wheel body 2 are pushed forward in a straight line until the polishing wheel body 2 is close to the workpiece to be processed. This is existing technology and will not be elaborated further here.

[0033] In specific implementation, a clamping device 3 is provided on one side of the polishing machine 1, and meshing gears are symmetrically provided in the clamping device 3, and the surface of the gears is provided with an arc-shaped shell; a circular cylinder is rotatably sleeved on the top of the clamping device 3, and the circular cylinder is fixed on the arc-shaped shell; a motor is installed at one end of the polishing machine 1, and gears are fixedly sleeved on the output end of the motor and the surface of the clamping device 3 respectively.

[0034] Additionally, it should be noted that the motor drives the meshing gears to rotate, and the rotation of the gears causes the polishing wheel body 2 to rotate synchronously. However, the rotation of the clamping device 3 will not cause the top circular column to rotate, and the protective shell 7 will always maintain a fixed posture and will not rotate with the polishing wheel body 2.

[0035] In specific implementation, a connecting column 4 is fixed on one side of the polishing machine 1, and a pin 5 is elastically limited on the inner wall of the connecting column 4. One side of the pin 5 is in contact with the bottom end of the adjusting rod 8, and the length of the bottom end of the pin 5 is longer than the bottom end of the polishing wheel body 2. In addition, it should be noted that when the pin 5 moves forward synchronously with the polishing wheel body 2, the initial pin 5 is slightly longer than the lowest position of the polishing wheel body 2. Later, as the polishing head 22 at the bottom end of the polishing wheel body 2 continues to process and wear, the overall diameter and height of the polishing head 22 will gradually and irreversibly shrink. When the subsequent workpiece is finished and the next workpiece is processed, it is difficult for the surface of the polishing head 22 to contact the workpiece, which affects the processing effect and requires the replacement of the polishing wheel body 2.

[0036] An adjusting rod 8 is movably sleeved on the surface of the ejector pin 5, and one side of the adjusting rod 8 is in contact with one side of the deformation plate 9. The bottom length of the adjusting rod 8 is slightly lower than the bottom of the polishing wheel body 2.

[0037] Additionally, it should be noted that the ejector pin 5 is movably inserted into the polishing wheel body 2. Within the polishing wheel body 2, it is driven by the force generated by the ejector pin 5 and the workpiece being squeezed and retracted, gradually moving backward in one direction. The bottom of the ejector pin 5 is always slightly lower than the front end of the polishing wheel body 2, and it is located within the polishing wheel body 2 without contacting the workpiece.

[0038] In specific implementation, a support plate 10 is provided in the hollow part of the inner wall of the polishing wheel body 2, and the support plate 10 is in contact with the inner wall of the polishing wheel body 2; the support plate 10 is composed of two parts: a disc-shaped plate and a rod, and the rod is evenly distributed at the bottom end of the support plate 10.

[0039] Additionally, it should be noted that as the ejector pin 5 drives the adjusting rod 8 to move backward, the adjusting rod 8 pushes the two sets of deformation plates 9 backward to compress and deform them. The lateral area of ​​the two sets of deformation plates 9 changes, gradually pushing the polishing head 22 to deform and extend in all directions. The support plate 10 is in direct contact with the polishing wheel body 2. When the polishing wheel body 2 rotates, it does not contact the top of the deformation plate 9. The deformation plate 9 is located behind the petals, and the elastic deformation of the polishing head 22 with the workpiece starts from its front end.

[0040] In specific implementation, the polishing wheel body 2 is composed of two parts: a polishing shank 21 and a polishing head 22. The polishing head 22 is elastically connected to one side of the polishing shank 21. The top of the polishing shank 21 is clamped and connected to the clamping device 3. The polishing heads 22 are independently set at equal angles, and the surfaces of every two sets of polishing heads 22 are provided with equal angles.

[0041] Additionally, it should be noted that, as shown in Figure 13, the width, thickness, and length of the petals of the polishing head 22 depend on the elasticity required by the workpiece, the depth and size of the counterbore depend on the workpiece, and the shape of the contour depends on the shape required by the workpiece. The shapes shown in this patent include, but are not limited to, those in Figure 13. The structure designed in this application is based on A in the figure as an example. All other polishing heads 22 are applicable. The polishing head 22 is an elastic material made of polyurethane elastomer and abrasive mixed and foamed.

[0042] Each individual "petal" of the polishing head 22 undergoes adaptive micro-deformation according to the microscopic contour of the workpiece surface during the initial contact stage, ensuring that it forms an initial surface contact rather than a point contact with the workpiece surface. As the polishing wheel rotates at high speed, under the action of centrifugal force, the free end of each "petal" will extend outward. At the same time, under the combined action of friction and extrusion force with the workpiece surface, the elastic matrix of the "petal" undergoes controllable bending deformation. This deformation allows the polishing abrasive to act evenly on the curved surface, edges, and concave and convex parts of the workpiece, ensuring the stability and uniformity of the cutting force during the polishing process. The gaps between the "petals" can dissipate heat and help impurities fall off.

[0043] As shown in Figure 13, the four different contour shapes are suitable for different workpieces. The curved and groove shapes can be processed according to the usage requirements to meet different polishing needs.

[0044] In practice, a protective shell 7 is fixed on one side of the clamping device 3, and movable columns 12 are symmetrically inserted in the protective shell 7; a pin 5 and an adjusting rod 8 are also movably inserted in the protective shell 7.

[0045] In specific implementation, a first hydraulic column 6 and a second hydraulic column 14 are fixed on one side of the clamping device 3, and the first hydraulic column 6 and the second hydraulic column 14 are connected to each other; the first hydraulic column 6 and the second hydraulic column 14 are respectively composed of a reservoir pipe, a piston rod and a return spring, and oil is provided in the first hydraulic column 6 and the second hydraulic column 14.

[0046] Additionally, it should be noted that after the ejector pin 5 is worn by the polishing head 22, the difference in distance between it and the workpiece is pushed onto the workpiece by the moving mechanism and squeezed back. Depending on the different distances, the squeezing force is different. The ejector pin 5 moves backward, causing the piston rod of the second hydraulic column 14 to retract and push different amounts of oil into the first hydraulic column 6. The amount of oil inside the first hydraulic column 6 increases, and at this time, the elastically connected ejector pin 5 is forced to retract.

[0047] In specific implementation, the movable column 12 consists of two parts: a triangular prism and a sliding rod. The triangular prism is movably inserted into the surface of the adjusting rod 8, and the surface of the adjusting rod 8 is provided with corresponding grooves at equal intervals. One side of the sliding rod is fixed to the triangular prism, and the other side of the sliding rod passes through the protective shell 7 and is movably inserted into it. A compression spring 13 is elastically sleeved on the surface of the sliding rod, and the two sides of the compression spring 13 are fixed to the inner wall of the protective shell 7 and one side of the triangular prism, respectively.

[0048] Additionally, it should be noted that as the ejector pin 5 moves backward, it synchronously pushes the adjusting rod 8 backward. The movement of the adjusting rod 8 causes the irregularly shaped locking block 11 to move synchronously. Subsequently, the moving columns 12 on both sides of the irregularly shaped locking block 11 move elastically to both sides along the inclined plane. One set of irregularly shaped locking blocks 11 moves backward behind the moving column 12. When the irregularly shaped locking block 11 stops moving, the moving column 12 limits the height of the irregularly shaped locking block 11. The irregularly shaped locking block 11 and the adjusting rod 8 move backward according to the different wear conditions of the polishing head 22, so that the deformation plate 9 continuously thins and pushes the polishing head 22 to spread out to both sides to compensate for the diameter. The diameter of the front end of the adjusting rod 8 is smaller than the distance between the two sets of moving columns 12, which facilitates the replacement and installation of the polishing wheel body 2.

[0049] In specific implementation, the deformation plate 9 is set in a mirror symmetrical manner, and the surface of the deformation plate 9 is set in an inclined shape; an arc-shaped groove is opened through the surface of the deformation plate 9 at equal angles, and a support plate 10 is movably inserted in the arc-shaped groove.

[0050] In addition, it should be noted that multiple sets of insert rods are inserted into the arc-shaped grooves of the deformation plate 9 to limit the displacement of the deformation plate 9, so that the deformation plate 9 always becomes thinner and spreads outwards, allowing the deformation plate 9 to maintain stable movement and continuously compensate for the diameter of the polishing head 22, so that it fits against the surface of the workpiece and maintains the polishing efficiency.

[0051] In specific implementation, the irregularly shaped card block 11 is set as a trapezoid, and the irregularly shaped card block 11 is coaxially and movably connected to the protective shell 7; the surface curvature of the irregularly shaped card block 11 is adapted to one side of the moving column 12, and the moving column 12 is movably inserted in the middle of every two sets of irregularly shaped card blocks 11.

[0052] Working principle: When using this petal-shaped elastic polishing wheel structure, first, firmly fix the workpiece on the polishing machine 1, select and install the polishing wheel body 2 into the clamping device 3 according to the requirements and tighten it securely, apply polishing paste evenly to the polishing head 22, and start the corresponding program so that the polishing wheel body 2 contacts the workpiece with appropriate pressure, and achieves grinding or polishing by friction.

[0053] After the polishing head 22 has been working for a period of time, the diameter and thickness of the surface of the polishing head 22 will irreversibly wear down and become smaller. Subsequently, after the next processing, the contact area between the worn polishing head 22 and the workpiece will become smaller, and the distance that the moving mechanism pushes the polishing head 22 forward will increase. However, the distance between the ejector pin 5 and the workpiece is fixed. The increase in the distance between the polishing head 22 and the ejector pin 5 will increase the distance that the ejector pin 5 retracts when it pushes the polishing wheel body 2 forward to contact the workpiece.

[0054] As the retraction distance of the ejector pin 5 increases, the adjusting rod 8 moves accordingly to the rearward position based on the degree of wear. The support plate 10 directly contacts the polishing wheel body 2. The adjusting rod 8 pushes the mirror-symmetrical deformation plate 9 backward to compress and deform it. The thickness of the two sets of deformation plates 9 decreases, gradually pushing the middle end of the polishing head 22 to deform and elastically extend in all directions. When the polishing wheel body 2 rotates, it does not contact the front end of the deformation plate 9. The deformation plate 9 is located behind the petals. Subsequently, the surface of the polishing head 22 comes into close contact with the surface of the workpiece.

[0055] When the adjusting rod 8 moves backward, it drives the irregularly shaped locking block 11 to move backward synchronously. The backward movement of the irregularly shaped locking block 11 pushes the moving columns 12 on both sides and the compression spring 13 to move to both sides and retract simultaneously. When the adjusting rod 8 drives the irregularly shaped locking block 11 to move backward to a suitable distance, the irregularly shaped locking block 11 of the corresponding height moves to the middle of the two sets of moving columns 12. The compression spring 13 pushes the moving column 12 to rebound and lock in the surface or middle of the corresponding irregularly shaped locking block 11. The moving column 12 is also inserted into the corresponding groove of the adjusting rod 8. The moving column 12 will not move with the rotation and displacement of the moving mechanism and the motor, stably limiting the adjusting rod 8 and the deformation plate 9 in one direction, so that the adjusting rod 8 and the deformation plate 9 can only move backward and to all directions in one direction, compensating for the continuous wear.

[0056] Finally, after the surface of the polishing head 22 comes into close contact with the surface of the workpiece, the motor is started to drive the polishing wheel body 2 to polish the workpiece. Each independent "petal" of the polishing head 22 will produce adaptive micro-deformation according to the micro-contour of the workpiece surface during the initial contact stage. Under the combined action of friction and extrusion force with the workpiece surface, the elastic matrix of the "petal" undergoes controllable bending deformation. The elastic deformation of the polishing head 22 and the workpiece starts from its front end. This deformation allows the polishing abrasive to act evenly on the curved surface, edges and concave and convex parts of the workpiece.

[0057] After the workpiece is processed, the moving mechanism drives the polishing wheel body 2 to reset, the elastically connected ejector pin 5 resets, the oil in the first hydraulic column 6 flows in reverse to the negative pressure second hydraulic column 14, and the ejector pin 5 moves backward in the adjusting rod 8. When the polishing head 22 is highly worn and difficult to use or when it is replaced with a different specification, the clamping device 3 is opened, the two sets of moving columns 12 are pulled apart to both sides at the same time, the adjusting rod 8 and the polishing wheel body 2 are taken out from the clamping device 3, and then the deformation plate 9 is taken out and a new polishing wheel body 2 is reinstalled for use.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
