Description

Technical Field

[0001] This disclosure relates to the field of machining technology, and in particular to a polishing fixing device. Background Technology

[0002] Polishing of finned components, such as finned heat sinks, is mostly done using hand tools or general-purpose polishing equipment. These existing technologies have the following main shortcomings: First, polishing quality and consistency are difficult to guarantee. Because cemented carbide fins are usually complex in shape and densely packed, general-purpose polishing equipment struggles to achieve uniform and comprehensive polishing of all fin surfaces, especially deep within the crevices. Manual polishing relies heavily on the operator's experience and skill; polishing pressure, angle, and path are difficult to standardize, resulting in poor product consistency, low yield, and inability to meet the demands of mass production. Second, existing tooling has poor adaptability and low efficiency. There is a lack of dedicated polishing tooling designed specifically for cemented carbide fins on the market. During polishing, the positioning and clamping of the fins are often unstable, easily vibrating or deforming under polishing force, affecting the polishing effect and even damaging the workpiece.

All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the protection scope of this disclosure.

[0018] Polishing of finned components, such as finned heat sinks, is mostly done using hand tools or general-purpose polishing equipment. These existing technologies have the following main shortcomings: First, polishing quality and consistency are difficult to guarantee. Because cemented carbide fins are usually complex in shape and densely packed, general-purpose polishing equipment struggles to achieve uniform and comprehensive polishing of all fin surfaces, especially deep within the crevices. Manual polishing relies heavily on the operator's experience and skill; polishing pressure, angle, and path are difficult to standardize, resulting in poor product consistency, low yield, and inability to meet the demands of mass production. Second, existing tooling has poor adaptability and low efficiency. There is a lack of dedicated polishing tooling designed specifically for cemented carbide fins on the market. During polishing, the positioning and clamping of the fins are often unstable, easily vibrating or deforming under polishing force, affecting the polishing effect and even damaging the workpiece.

[0019] To address the problems existing in related technologies, this disclosure provides a polishing fixing device. This device secures the workpiece to be polished using a fixing member, which is housed within the accommodating space of a mounting base, thus fixing the workpiece. The first and second ports at both ends of the mounting base are connected to the cylinder pipe and cylinder body pipe of the polishing equipment, respectively, allowing the polishing material to circulate between the first port, the polishing channel, and the second port under cylinder pressure, thereby polishing the workpiece located within the polishing channel. This polishing fixing device achieves stable fixation of the workpiece, preventing uneven polishing or even damage to the workpiece due to shaking during polishing. Furthermore, the polishing material can automatically polish the workpiece under cylinder pressure, reducing manual intervention and improving the polishing stability and product quality.

[0020] This disclosure provides a polishing fixing device, such as... Figure 1As shown, the polishing fixing device 100 includes a fixing member 10 and a mounting base 20. The fixing member 10 is provided with a polishing channel 11, and a fixing part 12 for fixing the workpiece to be polished (not shown in the figure) is provided in the polishing channel 11. The mounting base 20 has an accommodating space 21, and the fixing member 10 is disposed in the accommodating space 21. The mounting base 20 is provided with a first port (not shown in the figure) and a second port (not shown in the figure) at both ends of the polishing channel 11. The first port is used to communicate with the cylinder pipe of the polishing equipment, and the second port is used to communicate with the cylinder pipe of the polishing equipment, so that the polishing material can circulate between the first port, the polishing channel 11 and the second port, and the polishing material can polish the workpiece to be polished located in the polishing channel 11.

[0021] In this embodiment, based on the complex and tightly arranged finned structure of the workpiece to be polished (e.g., a finned structural component), the workpiece is fixed by a fixing member 10, which is housed in the receiving space 21 of the mounting base 20, thus fixing the workpiece. The first and second ports at both ends of the mounting base 20 are connected to the cylinder pipe and cylinder body pipe of the polishing equipment, respectively, so that the polishing material can circulate between the first port, the polishing channel 11, and the second port under cylinder pressure, thereby polishing the workpiece located in the polishing channel 11. The polishing fixing device 100 provided in this embodiment can stably fix the workpiece to be polished, avoiding uneven polishing or even damage to the workpiece due to shaking during the polishing process. Furthermore, the polishing material can automatically polish the workpiece under cylinder pressure, reducing manual intervention and improving the polishing stability and product quality.

[0022] For example, the polishing material can be a paste material containing high-strength particles such as silicon carbide and boron carbide.

[0023] In one embodiment, such as Figure 1 As shown, the polishing channel 11 includes a first wall surface 15 and a second wall surface 16 disposed opposite each other along a first direction 14 perpendicular to the extension direction of the polishing channel 11. The fixing part 12 includes a first fixing unit 151 and a second fixing unit 161. The first fixing unit 151 is disposed on the first wall surface 15, and the second fixing unit 161 is disposed on the second wall surface 16. The second fixing unit 161 cooperates with the first fixing unit 151 to fix the workpiece to be polished.

[0024] In this embodiment, by setting the first fixing unit 151 and the second fixing unit 161 on the two opposing surfaces of the first wall surface 15 and the second wall surface 16 respectively, clamping forces can be applied simultaneously from the opposite sides of the workpiece to be polished, forming opposing fixation. This fixing method is stable and can effectively resist the impact and friction generated by the polishing material flowing through it and the workpiece to be polished, preventing the workpiece to be polished from shaking or shifting during the polishing process, and ensuring the reliability of fixing the workpiece to be polished.

[0025] In one embodiment, such as Figure 1 As shown, the workpiece to be polished (e.g., a finned structure) located in the polishing channel 11 includes a fixing plate (e.g., the root of the finned structure) and multiple sheet-like structures (e.g., the fins of the finned structure). The multiple sheet-like structures are distributed sequentially at intervals along a second direction 141 perpendicular to the extension direction of the polishing channel. The second direction 141 is perpendicular to the first direction 14, and each sheet-like structure includes two opposing ends along the first direction 14. One of the two ends is connected to the fixing plate. The first fixing unit 151 is a first slot adapted to the fixing plate. The first slot is used to engage with the fixing plate. The second fixing unit 161 includes multiple slots corresponding to the multiple sheet-like structures. The slots are used to engage with the other end of the corresponding sheet-like structure.

[0026] In this embodiment, for a workpiece to be polished (e.g., a finned structure) comprising a fixing plate and multiple sheet-like structures, the fixing plate is fixed to the workpiece via a first slot, and multiple sheet-like structures are fixed to the workpiece via multiple slots respectively. This allows for precise positioning and fixation of the workpiece in the polishing fixing device 100, enabling it to effectively resist the impact and friction generated by the polishing material flowing through it. This prevents the workpiece from shaking or shifting during polishing, ensuring the reliability of its fixation. Simultaneous polishing of batches of workpieces is achieved, significantly improving production efficiency.

[0027] In one embodiment, such as Figure 2 As shown, the fixing part 12 also includes two limiting units, such as the first limiting unit 121 and the second limiting unit 122. The two limiting units are respectively disposed at both ends of the first slot in the second direction 141. The limiting units are used to abut against the fixing plate.

[0028] In this embodiment, the first limiting unit 121 and the second limiting unit 122 provided at both ends of the first slot (i.e. the first fixing unit 151) can firmly abut against the end face of the fixing plate from both sides. This can eliminate the possibility of displacement of the fixing plate and its connected sheet structure along the second direction 141, so that the workpiece to be polished can remain stable even under the impact of strong polishing material.

[0029] In one embodiment, combined with Figure 1 and Figure 2As shown, the fastener 10 includes at least three plate-like structures stacked in sequence, each plate-like structure having a hollow structure, and the hollow structures are connected to form a polishing channel 11. The fastener 12 is disposed in the hollow structure on the plate-like structure in the middle layer.

[0030] In this embodiment, the fixing member 10 is composed of at least three plate-like structures stacked sequentially. Therefore, during the polishing process, the at least three plate-like structures can be combined to form the fixing member 10 according to the shape of the polishing channel 11 or the workpiece to be polished. This allows the polishing fixing device 100 to adapt to different workpieces to be polished, expanding the application range of the polishing fixing device. In addition, the hollow structures of each plate-like structure of the fixing member 10 are connected to form the polishing channel 11. The workpiece to be polished is clamped and fixed on the fixing part 12 in the hollow structure of the middle plate-like structure. This allows space to be reserved on both sides of the workpiece to be polished for the flow of polishing material, so that the polishing material can circulate through the polishing channel 11, thereby achieving the polishing of the workpiece to be polished.

[0031] In one embodiment, a foolproof structure is provided between each adjacent plate-like structure.

[0032] In this embodiment, a foolproof structure is provided between each adjacent plate structure. This ensures that each layer of plate structure in the fastener is assembled according to the uniquely correct relative position and orientation during the assembly process, avoiding assembly errors. In addition, the foolproof structure between each adjacent plate structure also ensures that the edges of each layer of plate structure are aligned to form a polishing channel, and prevents leakage of polishing material due to gaps caused by misalignment between adjacent plate structures.

[0033] In one embodiment, the foolproof structure includes a protruding structure and a grooved structure that are adapted to be connected, the protruding structure being disposed on one of the adjacent plate-like structures and the grooved structure being disposed on the other of the adjacent plate-like structures.

[0034] In this embodiment, the anti-misfit structure formed by the protrusions and grooves between adjacent plate-like structures ensures that each layer of plate-like structures in the fastener can be assembled according to the uniquely correct relative position and direction during the assembly process, avoiding assembly errors. Furthermore, the anti-misfit structure formed between each adjacent plate-like structure also ensures that the edges of each layer of plate-like structure are aligned, forming a polishing channel, and prevents leakage of polishing material due to gaps caused by misalignment between adjacent plate-like structures.

[0035] In one embodiment, combined with Figure 1As shown, the mounting base 20 includes a sleeve structure 201, a pressure plate (not shown), and a base plate 203. The pressure plate is disposed at one end of the sleeve structure 201, and a first opening is located on the pressure plate. The base plate 203 is disposed at the other end of the sleeve structure 201, and a second opening is located on the base plate 203. The base plate 203, the pressure plate, and the sleeve structure 201 together enclose a receiving space 21. The pressure plate abuts against the outermost plate structure on one side of at least three plate-like structures along the extension direction of the polishing channel 11. The first opening is adapted to the perforated structure on the abutting plate-like structure. The base plate 203 abuts against the outermost plate structure on the other side of at least three plate-like structures along the extension direction of the polishing channel. The second opening is adapted to the perforated structure on the abutting plate-like structure.

[0036] In this embodiment, the sleeve structure 201, pressure plate, and base plate 203 in the mounting base 20 enclose a receiving space 21 to accommodate the fixing member 10. During the polishing process, it, together with the cylinder pipe and cylinder body pipe of the polishing equipment, forms a sealed polishing environment to prevent leakage of polishing material. When the receiving space 21 in the mounting base 20 accommodates the fixing member 10, the pressure plate abuts against the outermost plate-like structure on one side of the fixing member 10 along the extension direction of the polishing channel 11, and the base plate 203 abuts against the outermost plate-like structure on the other side of the fixing member 10 along the extension direction of the polishing channel. This end-face pressing method can press and fix the fixing member 10 in the receiving space 21. The first opening is adapted to the hollow structure on the abutting plate-like structure, and the second opening is adapted to the hollow structure on the abutting plate-like structure, which can ensure that the polishing material can smoothly circulate between the first opening, the polishing channel 11, and the second opening to polish the workpiece located in the polishing channel 11, reducing pressure loss and turbulence.

[0037] For example, the sleeve structure 201, pressure plate, and base plate 203 in the mounting base 20 can be designed as separate units, making the mounting base 20 easy to assemble to accommodate different fasteners 10 or parts to be polished. The assembly between the sleeve structure 201, pressure plate, and base plate 203 can be achieved by tightening the sleeve structure 201 and pressure plate, as well as the connecting parts between the sleeve structure 201 and base plate 203, such as bolts, thereby conveniently pressing and fixing the fastener 10, which consists of a multi-layer plate structure, within the accommodating space 21.

[0038] In one embodiment, a limiting groove is provided on the surface of the base plate facing the pressure plate, and the fastener is embedded in the limiting groove.

[0039] In this embodiment, a limiting groove is provided on the surface of the base plate facing the pressure plate, which can provide a precise and clear installation and fixing position for the fastener. When assembling the fastener with the mounting base, simply placing the fastener into the limiting groove is sufficient to position the fastener in the mounting base, eliminating the need for additional adjustment steps. This simplifies the assembly process of the polishing fixing device. Furthermore, the limiting groove on the base plate restricts the movement or rotation of the fastener on the base plate plane. Especially during the polishing process, when subjected to the flow friction and pressure of the polishing material, it also prevents the fastener from maintaining its position, thereby ensuring the polishing stability and product quality of the workpiece.

[0040] In one embodiment, the mounting base further includes a first connecting ring and a second connecting ring. The first connecting ring is disposed on the surface of the pressure plate opposite to the base plate, surrounding a first opening, and is used for a mating connection with a cylinder pipe. The second connecting ring is disposed on the surface of the base plate opposite to the pressure plate, surrounding a second opening, and is used for a mating connection with a cylinder block pipe.

[0041] In this embodiment, the first connecting ring adapts and connects one end of the first port of the mounting base to the cylinder pipe of the polishing device, and the second connecting ring adapts and connects one end of the second port of the mounting base to the cylinder pipe of the polishing device. This connecting ring structure increases the structural strength at the interface between the polishing fixing device and the polishing device, enabling the interface between the polishing fixing device and the polishing device to withstand higher pipe connection pre-tightening force and fluid pressure of the polishing material, thereby improving the connection stability between the polishing fixing device and the polishing device.

[0042] For example, the first connecting ring and the second connecting ring serve as the interface between the polishing fixing device and the polishing device. They can be quickly connected and separated from the feeding / discharging pipe through threaded connection, flange connection, or other means, which facilitates the installation, disassembly, and maintenance of the fixing device on the polishing equipment.
