Description

Technical Field

[0001] This application relates to the field of CNC machining equipment technology, and more specifically, to a machining tool. Background Technology

[0002] Machine tools typically generate a large amount of debris during processing. Therefore, a sheet metal casing is usually installed on the outside of the machine tool to prevent the debris from flying everywhere.

[0003] Sheet metal housings are typically made of a single-layer metal sheet, manufactured through stamping or thermoforming processes. However, such single-layer sheet metal housings offer poor vibration damping in high-vibration environments, making it difficult to meet the stability requirements of high-performance machine tools. In existing technologies, to improve the vibration damping effect of sheet metal housings, a rubber damping layer or a sound-absorbing material layer is usually added to the surface. This rubber damping layer or sound-absorbing material layer is fixed to the surface of the sheet metal housing using an adhesive layer. However, after prolonged use, the adhesive layer is prone to aging and peeling, leading to the detachment of the rubber damping layer or sound-absorbing material layer and a reduction in the vibration damping effect of the sheet metal housing. Utility Model Content

[0004] The main objective of this application is to provide a machining tool to solve the problem of poor stability of the rubber damping layer or sound-absorbing material layer on the sheet metal housing of the machine tool mentioned in the background art.

[0005] According to one aspect of this application, a machining tool is provided, comprising:

[0006] Processing main body;

[0007] The housing assembly includes multiple connecting parts that surround an installation space. The processing body is installed within the installation space. Each connecting part includes a first protective layer, a shock-absorbing layer, and a second protective layer. The shock-absorbing layer is installed between the first and second protective layers. The first protective layer is located on the side of the shock-absorbing layer closest to the installation space, and the second protective layer is located on the side of the shock-absorbing layer away from the installation space. The second protective layer and the first protective layer are connected by a locking structure.

[0008] Furthermore, the second protective layer is provided with a groove, the groove being located on the side of the second protective layer facing the installation space, and the damping layer is embedded in the groove, the damping layer being at least used to convert mechanical vibration energy into heat energy.

[0009] Furthermore, the damping layer includes at least one of a rubber layer, a polyurethane layer, and a composite fiber layer.

[0010] Furthermore, the second protective layer includes:

[0011] plate body;

[0012] The flanged portion is connected to the outer edge of the plate body, and the flanged portion and the plate body surround to form the groove. The outer edge of the shock-absorbing layer abuts against the inner peripheral sidewall of the flanged portion near the groove.

[0013] Furthermore, the flanged portion includes:

[0014] A first flange piece is connected to the plate body and extends along the outer periphery of the plate body;

[0015] The second flange is connected to the side of the first flange away from the plate, and the second flange and the first flange have a predetermined angle.

[0016] The first protective layer is disposed on the groove, and at least partially adheres to the second flange piece.

[0017] Furthermore, the locking structure includes:

[0018] The first through hole is disposed through the outer edge of the first protective layer;

[0019] The second through hole is disposed through the second flange piece;

[0020] A first fastener passes through the first through hole and the second through hole to fix the first protective layer to the second protective layer.

[0021] Furthermore, the first protective layer has an extension on at least one side along the first direction, the extension is bent toward the mounting space, and the side of the extension away from the mounting space is attached to the first flange piece.

[0022] Furthermore, the first flange and / or the second flange of two adjacent connecting components are fitted together, and the two adjacent connecting components are detachably connected by a second fastener.

[0023] Furthermore, the connecting component also includes:

[0024] A first support rib is disposed within the groove and extends along a first direction;

[0025] The second support rib is fixed in the groove and extends along the second direction. The second support rib includes at least two ribs, which are located on opposite sides of the width of the first support rib. The at least two ribs are perpendicularly connected to the first support rib, and the ends of the second support ribs away from the first support rib are fixedly connected to the inner wall of the groove.

[0026] Furthermore, the first protective layer is a one-piece molded bent structure.

[0027] Furthermore, the second protective layer is a one-piece molded bent structure.

[0028] In this application, by installing a damping layer between the first and second protective layers, the vibration damping performance of the machine tool is significantly improved. The damping layer effectively absorbs and disperses vibrations generated during machining, ensuring good stability and high machining accuracy even in high-vibration environments. This application meets the requirements of high-performance machine tools. The application employs a locking structure to fix the damping layer between the first and second protective layers. This connection method is more stable and less susceptible to the effects of time and environment, effectively ensuring the long-term stability and reliability of the damping layer. Because the damping layer is sandwiched between the first and second protective layers and fixed by the locking structure, it can be easily disassembled and reinstalled when maintenance or replacement is needed, reducing maintenance costs and time. The first and second protective layers not only provide stable support for the damping layer but also enhance the protective performance and structural strength of the machine tool, further effectively preventing contaminants such as debris and dust from entering the machine tool and protecting its precision components from damage.

[0037] See Figures 1 to 2 As shown, this application provides a machining tool. The machining tool includes a machining body and a housing assembly. The housing assembly includes a plurality of connecting parts 10, which surround and form an installation space. The machining body is installed within the installation space. Each connecting part 10 includes a first protective layer 11, a damping layer 12, and a second protective layer 13. The damping layer 12 is installed between the first protective layer 11 and the second protective layer 13. The first protective layer 11 is located on the side of the damping layer 12 closest to the installation space, and the second protective layer 13 is located on the side of the damping layer 12 away from the installation space. The second protective layer 13 is connected to the first protective layer 11 by a locking structure.

[0038] In this embodiment, by installing a damping layer 12 between the first protective layer 11 and the second protective layer 13, the vibration damping performance of the machine tool is significantly improved. The damping layer 12 can effectively absorb and disperse the vibration generated by the machine tool during processing, ensuring that the machine tool still has good stability and high processing accuracy in high-vibration environments. This application can meet the usage requirements of high-performance machine tools. This application uses a locking structure to fix the damping layer 12 between the first protective layer 11 and the second protective layer 13. This connection method is more stable and less affected by time and environment, effectively ensuring the long-term stability and reliability of the damping layer 12. Since the damping layer 12 is sandwiched between the first protective layer 11 and the second protective layer 13 and fixed by the locking structure, it can be easily disassembled and reinstalled when the damping layer 12 needs maintenance or replacement, reducing maintenance costs and time. The first protective layer 11 and the second protective layer 13 not only provide stable support for the damping layer 12, but also enhance the protective performance and structural strength of the machine tool, further effectively preventing contaminants such as debris and dust from entering the machine tool and protecting the precision components of the machine tool from damage.

[0039] Furthermore, a groove 131 is provided on the second protective layer 13. The groove 131 is located on the side of the second protective layer 13 facing the installation space, and the damping layer 12 is embedded in the groove 131. The damping layer 12 is used at least to convert mechanical vibration energy into heat energy. The groove 131 provides a clear positioning for the installation of the damping layer 12, allowing the damping layer 12 to be accurately embedded in the groove 131. This makes it easier and more accurate for operators to place the damping layer 12 into the groove 131, improving the efficiency and accuracy of the assembly of the damping layer 12. The groove 131 also ensures that the damping layer 12 has good stability and positional accuracy when the machine tool is working, effectively preventing displacement of the damping layer 12. This helps the damping layer 12 to more effectively absorb and disperse vibration, reducing the impact of vibration on the machining accuracy of the machine tool. When the machine tool vibrates during processing, the vibration is transmitted to the damping layer 12. The damping layer 12 can convert the received mechanical vibration energy into heat energy and dissipate it in a timely manner, thereby effectively consuming the vibration energy and reducing the impact of vibration on the machine tool.

[0040] Furthermore, the damping layer 12 includes at least one of a rubber layer, a polyurethane layer, and a composite fiber layer. The rubber layer possesses excellent elasticity and damping properties; it can undergo elastic deformation when subjected to vibration, converting mechanical energy into heat energy and dissipating it. This effectively absorbs and isolates vibrations generated by the machining body, reducing vibration transmission and providing excellent damping for the machine tool, thus contributing to improved machining accuracy and stability. The rubber layer also exhibits good resistance to common chemicals and environmental contaminants such as oil and coolant, making it less susceptible to corrosion and extending the service life of the damping layer 12.

[0041] The polyurethane layer possesses high elastic modulus and strength. When subjected to significant vibration and impact, it maintains good shape and performance, resisting permanent deformation or cracking. It effectively absorbs and disperses vibrations from the housing components, providing reliable shock absorption for machine tools. Furthermore, the polyurethane layer exhibits good adhesion to materials such as metals. During installation and use, it bonds well with the first protective layer 11 and the second protective layer 13, ensuring the stability of the damping layer 12 and effectively reducing problems such as decreased shock absorption due to weak adhesion.

[0042] The composite fiber layer possesses high strength and modulus, enabling it to withstand significant tensile and compressive stresses. While absorbing vibrations, the composite fiber layer provides structural support to the housing assembly, enhancing its stability and reliability. Under the long-term vibration environment of machine tools, the composite fiber layer can withstand repeated loads without easily experiencing fatigue failure, ensuring the long-term stable operation of the damping layer 12 and reducing the need for frequent replacements due to its failure. The composite fiber layer has a low density, which, while maintaining damping effect and structural strength, reduces the weight of the housing assembly, facilitating handling and installation.

[0043] The shape of the damping layer 12 can be cut and adjusted according to the shape of the first protective layer 11 and the second protective layer 13 to ensure that the damping layer 12 can fully fill the space between the first protective layer 11 and the second protective layer 13, and to ensure that the shell assembly has good damping performance.

[0044] Furthermore, the second protective layer 13 includes a plate 132 and a flange 133. The flange 133 is connected to the outer edge of the plate 132, and the flange 133 and the plate 132 form a groove 131. The outer edge of the damping layer 12 abuts against the inner peripheral sidewall of the flange 133 near the groove 131. The abutment between the outer edge of the damping layer 12 and the inner peripheral sidewall of the flange 133 ensures that after vibration is transmitted to the second protective layer 13, it can be transmitted to the damping layer 12 along the flange 133, ensuring that the damping layer 12 can efficiently absorb and convert vibration. This embodiment also enables the damping layer 12 to be stably confined within the groove 131, effectively limiting the displacement of the damping layer 12 in all directions, effectively preventing the damping layer 12 from loosening, shifting, or falling off due to vibration or other factors during the operation of the processing body, ensuring good stability of the damping layer 12, and ensuring that the processing machine tool has good vibration damping performance. The flange 133 is connected to the outer edge of the plate 132, which increases the rigidity and strength of the second protective layer 13. The flange 133 can help the plate 132 resist deformation better, making the second protective layer 13 itself more stable, thereby providing more reliable protection and support for the internal shock-absorbing layer 12 and the processing body, and improving the anti-interference ability of the processing machine tool.

[0045] Furthermore, the flange portion 133 includes a first flange piece 1331 and a second flange piece 1332. The first flange piece 1331 is connected to the plate body 132 and extends along the outer periphery of the plate body 132. The second flange piece 1332 is connected to the side of the first flange piece 1331 away from the plate body 132, and the second flange piece 1332 and the first flange piece 1331 have a predetermined angle. A first protective layer 11 is disposed over the groove 131, and the first protective layer 11 is at least partially in contact with the second flange piece 1332. The first flange piece 1331 and the second flange piece 1332 form a multi-layered connection structure. The first flange piece 1331 extends along the outer periphery of the plate body 132, providing outward extension support for the plate body 132 and enhancing the rigidity of the edge portion of the plate body 132. The second flange 1332 is connected to the first flange 1331, further enhancing the stability of the plate 132 and ensuring that the second protective layer 13 can better resist external impacts and stresses caused by machine tool vibration, thereby ensuring the overall structural stability of the second protective layer 13 and providing a stable protective environment for the internal processing body. The first protective layer 11 is at least partially attached to the second flange 1332, facilitating the quick installation of the first protective layer 11 onto the second protective layer 13 and providing a clear installation positioning reference for the first protective layer 11. Operators can easily and accurately place the first protective layer 11 and attach it to the second flange 1332 based on the position and shape of the second flange 1332, thus completing the connection between the first protective layer 11 and the second protective layer 13. This simplifies the installation steps, improves the assembly efficiency of the housing assembly, and also helps to improve the stability of the connection between the first protective layer 11 and the second protective layer 13. In addition, the first protective layer 11 is at least partially attached to the second flange 1332, which can reduce the gap between the first protective layer 11 and the second protective layer 13, and prevent graphite dust, debris and other fine particles from entering the groove 131 and contaminating the shock-absorbing layer 12.

[0046] Furthermore, the locking structure includes a first through hole 141, a second through hole 142, and a first fastener. The first through hole 141 is disposed through the outer edge of the first protective layer 11. The second through hole 142 is disposed through the second flange 1332. The first fastener passes through the first through hole 141 and the second through hole 142 to fix the first protective layer 11 to the second protective layer 13. By providing the first through hole 141 and the second through hole 142 and using the first fastener to connect the first protective layer 11 and the second protective layer 13, this mechanical connection method is more stable and reliable than traditional bonding and other connection methods. During the long-term operation of the machine tool, the damping layer 12 provided in this embodiment has higher stability, and the damping layer 12 is not prone to loosening, falling off, or other connection failures, ensuring that the machine tool has good damping performance for a long time. The operator only needs to align the first through hole 141 on the first protective layer 11 with the second through hole 142 on the second flange 1332, then insert the first fastener and tighten it, greatly improving the assembly efficiency of the housing assembly. When replacing the damping layer 12, simply loosen the first fastener to separate the first protective layer 11 and the second protective layer 13, and remove the damping layer 12 for replacement. Replacing the damping layer 12 is simple. The first fastener can be a screw, but is not limited to this; this embodiment does not impose a single limitation.

[0047] Furthermore, the first protective layer 11 has an extension 111 on at least one side along a first direction (the first direction is indicated by arrow X in the figure, specifically the extension direction of the plate 132). The extension 111 is bent towards the mounting space, and the side of the extension 111 facing away from the mounting space is attached to the first flange 1331. The attachment of the extension 111 to the first flange 1331 further increases the contact area and the degree of attachment between the first protective layer 11 and the second protective layer 13, ensuring that the first protective layer 11 can be more stably installed on the second protective layer 13, and also improving the stability of the housing assembly. At the same time, the extension 111 also has a certain limiting effect on the shock-absorbing layer 12, preventing the shock-absorbing layer 12 from slipping out of the groove 131.

[0048] Furthermore, the first flange 1331 and / or the second flange 1332 of two adjacent connecting parts 10 are fitted together, and the two adjacent connecting parts 10 are detachably connected by a second fastener. Multiple connecting parts 10 are detachably connected by connecting parts 10. The modular design of the connecting parts 10 makes them easier to transport, install, and disassemble, effectively reducing transportation costs and space requirements. Workers can also assemble and splice the connecting parts 10 more flexibly according to the actual installation environment and operating space. The modular design of the connecting parts 10 also facilitates maintenance, eliminating the need to disassemble the entire housing assembly, reducing maintenance difficulty, saving time and effort, and lowering maintenance costs. The modular design of the connecting parts 10 also provides high flexibility. By changing the number and shape of the connecting parts 10, the shape of the housing assembly can be flexibly adjusted, allowing the housing assembly to be flexibly adapted to various specifications of machine tools, meeting diverse production requirements and further expanding the applicability of the machine tool. Based on the positional relationship between adjacent connecting components 10, adjacent connecting components 10 can be connected via their respective first flange 1331 and second flange 1332, improving the flexibility of connection between connecting components. Multiple connecting holes can be provided on the first flange 1331 and second flange 1332, and second fasteners pass through these connecting holes to fix the multiple connecting components 10 together. The second fastener can be a screw, which passes through the connecting holes to connect and fix the multiple connecting components 10 together. Other structures for the second fastener are also possible; this embodiment is not limited to only one.

[0049] Furthermore, the connecting component 10 also includes a first support rib 15 and a second support rib 16. The first support rib 15 is disposed within the groove 131 and extends along a first direction. The second support rib 16 is fixed within the groove 131 and extends along a second direction. At least two second support ribs 16 are included, each located on opposite sides of the width of the first support rib 15, and both are perpendicularly connected to the first support rib 15. The ends of the second support ribs 16 away from the first support rib 15 are fixedly connected to the inner wall of the groove 131. The first support rib 15 extends along the extension direction of the second protective layer 13, providing strong support for the second protective layer 13 in the first direction. This effectively resists deformation of the groove 131 in the first direction caused by vibration, external impact, or other factors from the machine tool, thus strengthening the structural rigidity of the groove 131. Simultaneously, multiple second support ribs 16 are perpendicularly connected to the first support rib 15 along a second direction, further strengthening the structural strength of the second protective layer 13 in the second direction. Meanwhile, the first support rib 15 and the second support rib 16 work together to reinforce the second protective layer 13, greatly improving the overall structural strength of the second protective layer 13. This allows the second protective layer 13 to more stably support components such as the shock-absorbing layer 12, ensuring the stability of the shock-absorbing layer 12 and providing a reliable structural foundation for the normal operation of the machine tool. The first direction is the extension direction of the second protective layer 13, and the second direction is perpendicular to the first direction. Figure 1 The direction indicated by the middle arrow Y. The first support rib 15 and the second support rib 16 are welded within the groove 131.

[0050] Furthermore, the first protective layer 11 is a one-piece molded bent structure.

[0051] Furthermore, the second protective layer 13 is a one-piece bent structure. According to actual needs, the first protective layer 11 and the second protective layer 13 can be formed into the required shape through a bending process. The bending process is lower in cost, easier to manufacture, and more flexible, and can be formed into the required shape as needed.

[0052] like Figures 1 to 2As shown, this application has the following beneficial effects: (1) Multi-layer composite design of damping materials such as embedded damping layer 12. The damping layer 12 is embedded between the first protective layer 11 and the second protective layer 13 to form a three-layer composite structure. This design significantly improves the vibration absorption and noise attenuation capabilities of the housing assembly. The damping material can not only absorb the vibration energy during machine tool operation, but also convert vibration into heat energy through internal friction, thereby effectively reducing the transmission of vibration to the outside or inside the machine tool. The damping material is optimized according to the vibration frequency characteristics of the application scenario. For example, rubber material is suitable for high-frequency vibration attenuation, polyurethane foam is suitable for low-frequency vibration control, and metal honeycomb structure has both high strength and multi-frequency damping capability. (2) Innovative connection process design. The first reinforcing rib and the second reinforcing rib form a frame structure through welding process. The welding part is optimized and has high strength and fatigue resistance, ensuring the overall rigidity and long service life of the second protective layer 13. The first protective layer 11 and the second protective layer 13 are detachably connected, which not only enhances the firmness of the connection part, but also makes the maintenance of the structure and the replacement of the damping layer 12 simple and convenient. The locking structure, through reasonable distribution, avoids structural deformation or failure caused by stress concentration. Welding provides basic rigidity, and the first fastener enhances flexibility and maintainability. The combination of the two not only simplifies the production process but also optimizes the overall structural performance. (3) Flexibility and maintainability of modular design. The first protective layer 11, the damping layer 12, and the second protective layer 13 of this application are all modularly designed and can be disassembled and replaced individually. Different components can be flexibly selected in terms of materials and specifications according to the specific usage environment to meet various application requirements. The modular design makes maintenance easier. Users can quickly replace the damaged damping layer 12 and the second protective layer by simply removing the screws, thereby significantly reducing maintenance costs and downtime. In addition, the upgrade and replacement of the damping layer 12 can also be adjusted according to the damping requirements at different stages. (4) Damping design adapted to multi-frequency vibration. Through the reasonable selection of the damping layer 12 and the sandwich distribution design, the shell assembly of this application can absorb high-frequency and low-frequency vibrations at the same time, avoiding the limitations of traditional sheet metal structures in single-frequency vibration control. The internal friction of the damping layer 12 can convert vibration into heat energy dissipation. At the same time, the multi-layer structure isolates the propagation path of vibration, reducing the impact of vibration on the core components of the equipment (such as spindles and cutting tools) during the operation of the machine tool, and improving the machining accuracy. (5) Combining vibration reduction and noise reduction with environmental protection. By embedding the damping layer 12, the noise level of the machine tool during operation can be effectively reduced, reducing noise pollution to the operating environment and operators, which meets modern environmental protection and occupational health requirements. The damping layer 12 can be made of recyclable or environmentally friendly materials, further reducing the impact of the production process and waste disposal on the environment. (6) Simplification of production process and cost optimization. Elimination of traditional hot pressing and stamping processes: Compared with traditional sheet metal manufacturing processes, this application avoids the high requirements of hot pressing and stamping on equipment and energy consumption by welding and screw connection, significantly reducing manufacturing difficulty and cost.Highly adaptable manufacturing process: The structural design of this application is highly flexible and can adapt to customized production needs of various sizes and specifications, while maintaining high efficiency and consistency in large-scale production. (7) Improved structural reliability and service life. Mechanical advantages of composite structure: The first protective layer 11, the damping layer 12 and the second protective layer 13 are closely integrated, which makes the whole structure exhibit excellent rigidity and fatigue resistance when subjected to dynamic loads and impacts, significantly improving the overall reliability of the structure. Stable performance in long-term use: Due to the modular and maintainable design, this application can maintain good vibration and noise reduction effect in long-term use, and the service life of the overall structure can be extended by regularly replacing the damping layer 12.
