Description

Technical Field

[0001] This invention relates to the field of machine tool protection technology, and more specifically, to a protective mechanism and processing equipment having the same. Background Technology

[0002] In the current field of CNC machine tools, traditional protective sheet metal structures are widely used in various machining centers and mill-turning composite machine tools to isolate the machining area from the external environment and prevent the intrusion of contaminants such as cutting fluid, metal chips, dust, and oil mist. However, existing protective sheet metal technologies have significant limitations and shortcomings, which are mainly reflected in the following aspects:

[0003] 1. Sealing defects: Traditional single-layer sealing designs at sheet metal joints, using simple materials such as sealing strips or sponges, are insufficient to effectively prevent contaminants from penetrating in the long term. As the machine continues to run, the sealing material gradually ages, hardens, or wears down, leading to a decrease in sealing performance. Cutting fluid and fine dust can easily enter the machine tool, corroding precision components, reducing machining accuracy, and increasing maintenance frequency.

[0004] 2. Insufficient rigidity and vibration issues: In large CNC machine tools, the flat sheet metal structure of the protective cover lacks sufficient internal support, making it prone to vibration and noise under high-speed machining conditions. These vibrations not only affect the dynamic accuracy of the machine tool, but may also cause screws at connection points to loosen, seals to fail, further exacerbating the intrusion of contaminants and affecting the overall performance and stability of the machine tool.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] As mentioned in the background section, traditional single-layer sealing designs at sheet metal joints, using simple materials such as sealing strips or sponges, are insufficient to effectively prevent contaminant penetration in the long term. Furthermore, the flat sheet metal structure of the protective cover lacks sufficient internal support, making it prone to vibration and noise under high-speed machining conditions. These vibrations not only affect the dynamic accuracy of the machine tool but may also cause screws at connection points to loosen, leading to seal failure and further exacerbating contaminant intrusion, thus affecting the overall performance and stability of the machine tool. Therefore, to address the aforementioned technical problems, the protective mechanism provided in this application includes a protective body 100, a door panel assembly 200, and a buffer component 300. The door panel assembly 200 includes a first door panel 210 and a second door panel 220. The first door panel 210 is provided with a first sealing part 230, and the second door panel 220 is provided with a second sealing part 240. The first sealing part 230 and the second sealing part 240 are interlocked to keep the first door panel 210 and the second door panel 220 in a closed position. The buffer component 300 is disposed on the protective body 100, and at least a portion of the buffer component 300 is retractably configured. The interlocking between the first sealing part 230 and the second sealing part 240 effectively prevents the penetration of cutting fluid, metal shavings, dust, or oil mist. The addition of the buffer component 300, especially the retractable design on the protective body 100, effectively improves the vibration and noise problems of the protective cover under high-speed machining conditions. The buffer component 300 can provide flexible support and compensation during machine tool movement, absorb some vibration energy, reduce the transmission of vibration to the interior of the protective structure, and avoid the possibility of loosening of screws at the connection points due to vibration, thereby enhancing the structural stability and sealing reliability of the entire protective system.

[0030] Please refer to Figures 1 to 6 This application provides a protective mechanism, comprising: a protective body 100, wherein a mounting cavity 101 is provided within the protective body 100 for mounting a target workpiece; a door panel assembly 200, disposed on the protective body 100, wherein at least a portion of the door panel assembly 200 is movably disposed to allow the mounting cavity 101 to open or close; the door panel assembly 200 includes a first door panel 210 and a second door panel 220, wherein a first sealing portion 230 is provided on the first door panel 210 and a second sealing portion 240 is provided on the second door panel 220, wherein the first sealing portion 230 and the second sealing portion 240 are fitted together to allow the first door panel 210 and the second door panel 220 to be in a closed position; and a buffer member 300, disposed on the protective body 100, wherein at least a portion of the buffer member 300 is retractably disposed.

[0031] In its implementation, the protective mechanism provided in this application features a semi-enclosed structure 100 with an internal mounting cavity 101 for accommodating and protecting the target workpiece. The protective body 100 is typically made of high-strength sheet metal to ensure overall structural rigidity and protective durability. The mounting cavity 101 is designed with the workpiece's dimensions and working environment in mind, ensuring adequate protection of the workpiece in a sealed state while allowing sufficient space to accommodate movement during processing.

[0032] As a key component of the protective body 100, the door panel assembly 200 is designed to achieve convenient opening and reliable sealing of the mounting cavity 101. The door panel assembly 200 consists of a first door panel 210 and a second door panel 220, both of which are mounted on the protective body 100 and can be moved according to operational needs. The first sealing part 230 on the first door panel 210 and the second sealing part 240 on the second door panel 220 form a tight contact when the door is closed. Through this interlocking mechanism, even in harsh processing environments, it effectively prevents the intrusion of contaminants such as cutting fluid, metal shavings, dust, and oil mist.

[0033] The design of the buffer component 300 takes into account the stability of the protective mechanism under high-speed movement or impact. By providing the retractable buffer component 300 on the protective body 100, additional cushioning and vibration reduction effects can be provided during the movement of the door panel assembly 200.

[0034] The dual sealing design of the first sealing part 230 and the second sealing part 240 greatly enhances the sealing effect of the protective mechanism, effectively preventing external contaminants from entering the mounting cavity 101, protecting the internal workpiece and the precision components of the machine tool, reducing maintenance costs and failure rate, and extending the service life of the machine tool.

[0035] The movable design of the door panel assembly 200 allows operators to quickly and easily open and close the mounting cavity 101, facilitating the loading and unloading of workpieces and the maintenance and inspection of internal machine tool components, thereby improving production efficiency and equipment flexibility.

[0036] The introduction of the buffer component 300 effectively reduces the vibration and noise of the machine tool during high-speed machining or external impact, protects the sealing structure of the protective mechanism, ensures the dynamic accuracy of the machine tool, and reduces the need for additional inspections and adjustments caused by vibration during maintenance.

[0037] Specifically, such as Figures 4 to 6As shown, the first sealing part 230 includes a first receiving groove 231, which is disposed on the first door panel 210 and extends along the length direction of the first door panel 210; at least a portion of the second sealing part 240 is embedded in the first receiving groove 231, and at least a portion of the second sealing part 240 is in contact with the groove wall surface of the first receiving groove 231, so that the first door panel 210 and the second door panel 220 are in the closed position.

[0038] The first receiving groove 231 on the first sealing part 230 extends along the length of the first door panel 210, and at least a portion of the second sealing part 240 can be embedded in this groove. This interlocking design is more reliable than a single-layer seal because it can form a tighter contact when the door panel is closed, and can maintain a seal even under stress, effectively preventing contaminants from penetrating through the seams.

[0039] In this embodiment, the first receiving groove 231 and the second sealing part 240 are made of highly elastic and wear-resistant sealing materials, such as silicone or EPDM (ethylene propylene diene monomer) foam sealing strips. These materials can be compressed during fitting to form a micro-gap airtight seal, further improving the reliability of the seal.

[0040] At least a portion of the second sealing part 240 is in contact with the groove wall of the first receiving groove 231, ensuring that the sealing structure will not fail due to displacement even during the opening and closing of the door panel. At the same time, this design also ensures the continuity of the seal and avoids gaps caused by improper installation or aging of traditional sealing strips.

[0041] Even under high-speed motion or vibration conditions, the design of the second sealing part 240 embedded in the first receiving groove 231 can ensure the sealing effect of the door panel assembly when it is in the closed position, avoiding the common problem of dynamic seal failure.

[0042] The first sealing part 230 further includes a first folding plate 232, a second folding plate 233 and a third folding plate 234 that are connected to each other. The first folding plate 232 is connected to the first door panel 210 and is disposed opposite to the third folding plate 234. The first folding plate 232, the second folding plate 233 and the third folding plate 234 form a first receiving groove 231.

[0043] The folded groove formed by the combination of the first folding plate 232, the second folding plate 233, and the third folding plate 234 can be embedded in and enclose the second sealing part 240 of the second door panel 220, forming a labyrinthine sealing path. This multi-layered sealing path increases the difficulty of contaminant penetration, especially under complex working conditions (such as high-pressure cutting fluid injection, strong airflow generated by high-speed cutting, etc.), effectively preventing the direct intrusion of contaminants such as cutting fluid and dust, and improving the overall sealing performance of the protection system.

[0044] The bending structure of the first fold plate 232, the second fold plate 233, and the third fold plate 234 increases the lateral and longitudinal strength of the material compared to flat sheet metal, reducing the possibility of deformation or vibration in high-speed working environments. This structural design not only enhances the rigidity of the door panel itself, but also reduces stress concentration during the opening and closing process through the mechanical dispersion effect of the folding structure, thus extending the service life of the door panel and the sealing parts.

[0045] The second sealing part 240 includes: a first protruding plate 241 disposed on the second door panel 220, the first protruding plate 241 extending toward the first door panel 210 relative to the second door panel 220, and at least a portion of the first protruding plate 241 being embedded in the first receiving groove 231 so that the first door panel 210 and the second door panel 220 are in the closed position.

[0046] The first protruding plate 241 extends from the second door plate 220 toward the first door plate 210 and is embedded in the first receiving groove 231 formed on the first door plate 210. This fitting structure not only physically connects the first door plate 210 and the second door plate 220 tightly, but also ensures a tight seal when the door plates are closed through designed tolerances and material elasticity. Even in harsh working environments, cutting fluid and dust are unlikely to enter the machine tool interior through the door plate seams.

[0047] The engagement of the first protruding plate 241 with the first receiving groove 231 not only provides a seal at the straight edge of the door panel, but also achieves the continuity of the seal at non-straight or irregular shapes of the door panel edge through its deformability, avoiding the installation difficulties and potential leakage points of traditional sealing strips at complex shapes.

[0048] The engagement between the first protruding plate 241 and the first receiving groove 231 not only enhances the structural stability of the door panel assembly 200 and reduces vibration and noise that may occur during high-speed machine tool operation, but also simplifies the opening and closing process of the door panel. When closing the door panel, the operator only needs to ensure that the first door panel 210 and the second door panel 220 are aligned, and the first protruding plate 241 naturally slides into the first receiving groove 231, which quickly achieves a tight seal and stable closure of the door panel without the need for additional fasteners or complicated operations.

[0049] The second sealing part 240 further includes: a second protruding plate 242 disposed on the second door panel 220, the second protruding plate 242 extending toward the direction of the first door panel 210 relative to the second door panel 220, the second protruding plate 242 and the first protruding plate 241 being disposed opposite to and spaced apart, a second receiving groove 243 being disposed between the second protruding plate 242 and the first protruding plate 241, and at least a portion of the third folding plate 234 being embedded in the second receiving groove 243 so that the first door panel 210 and the second door panel 220 are in the closed position.

[0050] The second protruding plate 242 is disposed on the second door panel 220, extending toward and towards the first door panel 210, forming a relative and spaced arrangement with the first protruding plate 241. The purpose of this design is to create a more complex sealing path when the two door panels are closed, thereby enhancing the sealing effect.

[0051] The relative arrangement between the second protruding plate 242 and the first protruding plate 241 ensures that they are tightly aligned when the door is closed, forming a barrier. The second receiving groove 243 designed between the two plates cooperates with the third folding plate 234 on the first door panel 210, allowing at least a portion of the third folding plate 234 to be embedded within the second receiving groove 243. This engagement not only defines the relative position of the first door panel 210 and the second door panel 220, ensuring tight contact in the closed state, but also provides additional cushioning and deformation space when the sealing part is subjected to external pressure or impact, preventing direct damage to the sealing part and maintaining the reliability of the seal.

[0052] The design of the second receiving groove 243 provides a certain deformation space for the third folding plate 234, which can absorb external impacts and pressures, reduce direct wear and damage to the sealing structure, thereby extending the service life of the sealing part and reducing maintenance costs.

[0053] In this application, the protective mechanism further includes: a first sealing member disposed within the first sealing portion 230 and / or the second sealing portion 240, the first sealing member extending along the length direction of the first sealing portion 230 and / or the second sealing portion 240, the first sealing portion 230 and the second sealing portion 240 fitting together, and at least a portion of the first sealing portion 230 and / or at least a portion of the second sealing portion 240 abutting against the first sealing member.

[0054] The first seal is preferably made of a material with good elasticity and weather resistance, such as silicone, EPDM rubber or other polymer elastomers, which can adapt to different temperature and humidity changes and maintain long-term sealing performance.

[0055] The first seal is arranged along the entire length of the first sealing portion 230 or the second sealing portion 240 to ensure consistent sealing performance throughout the entire door opening and closing path. When the door is closed, the first sealing portion 230 and the second sealing portion 240 achieve a tight fit through complementary and interlocking shapes. At this time, the first seal and the corresponding sealing portion undergo slight compression deformation, thereby forming a sealing barrier. The thickness and hardness of the first seal can be adjusted according to actual needs to adapt to sealing requirements at different speeds and pressure levels.

[0056] To further improve the reliability and durability of the seal, the first seal can be designed with a lip so that when the door panel is closed, the lip can penetrate into the groove of the other seal to form a deeper sealing interface. This design can effectively cope with minor geometric irregularities or wear, ensuring that the sealing performance will not significantly decrease even with long-term use or in harsh environments.

[0057] The addition of the first seal makes the seal between the first door plate 210 and the second door plate 220 tighter and more durable, effectively resisting the invasion of various contaminants and protecting the inside of the machine tool from damage, thereby significantly improving the reliability and service life of the machine tool.

[0058] The first sealing part 230 includes a first receiving groove 231, and the second sealing part 240 includes a first protruding plate 241; the first sealing element includes: a first sealing body disposed on the groove wall surface of the first receiving groove 231, the first sealing body extending along the length direction of the first receiving groove 231; a second sealing body disposed on the first protruding plate 241, the second sealing body extending along the length direction of the first protruding plate 241, the first protruding plate 241 being embedded in the first receiving groove 231, and the first sealing body and the second sealing body fitting together; wherein, the first sealing body and the second sealing body are respectively elastically disposed.

[0059] The first receiving groove 231 is precisely positioned at the edge of the first door panel 210, and its shape and size match the first protruding plate 241. It extends along the length of the first door panel 210, ensuring continuous sealing along the entire length of the door panel. The first sealing body is firmly fixed to the groove wall of the first receiving groove 231 and is typically made of a highly elastic material, such as silicone or EPDM rubber, which can withstand compression and tension and maintain long-term sealing performance.

[0060] The second sealing part 240 includes a first protruding plate 241, which extends from the second door panel 220 when the second door panel 220 is closed and is accurately embedded in the first receiving groove 231. A second sealing body on the first protruding plate 241 also extends along its length and is made of a similar or identical material to the first sealing body, possessing good elasticity. When the second door panel 220 is fully closed, the first protruding plate 241 is fully embedded in the first receiving groove 231, and the first sealing body and the second sealing body achieve a tight fit on the contact surface.

[0061] The elastic design of the first and second sealing bodies allows for minute elastic deformation at the contact surface when the door panel is closed, forming an effective sealing ring. Even with slight displacement of the door panel due to long-term use, the continuity and tightness of the seal are maintained. This elastic sealing structure can adapt to various temperature and pressure changes, maintaining a stable sealing effect.

[0062] The protective body 100 includes: a first side plate portion 110 and a second side plate portion 120 disposed opposite to each other, the first side plate portion 110 and the second side plate portion 120 being connected by a top plate 130; the top plate 130 is provided with an avoidance opening 131, at least a portion of a buffer member 300 is located at the avoidance opening 131, both ends of the buffer member 300 are respectively connected to the first side plate portion 110 and the second side plate portion 120, the buffer member 300 is provided to extend and retract along the length direction of the avoidance opening 131, the length direction of the avoidance opening 131 being the direction from the first side plate portion 110 to the second side plate portion 120.

[0063] In the protective mechanism of this application, the protective body 100 is carefully designed as a semi-enclosed frame structure, wherein the first side plate 110 and the second side plate 120 are arranged opposite each other and are connected to each other through the top plate 130 to form a stable protective shell. The top plate 130 is specially provided with an avoidance opening 131, a design intended to provide space for the arrangement of the buffer component 300. The two ends of the buffer component 300 are respectively connected to the first side plate 110 and the second side plate 120. This connection method ensures that the buffer component 300 can freely extend and retract along the length direction of the avoidance opening 131 in the direction from the first side plate 110 to the second side plate 120.

[0064] The buffer component 300 can be implemented using a variety of retractable structures, such as springs, dampers, compressible elastic materials, or bellows covers. Its design not only takes into account the stability and safety of the protective mechanism under external impact or vibration, but also optimizes the smoothness and quietness of the door panel assembly 200 during closing and opening.

[0065] The expansion and contraction characteristics of the buffer component 300 can absorb the impact force of the door panel assembly 200 during opening and closing, significantly reducing vibration and noise caused by sudden opening and closing. The presence of the buffer component 300 not only improves the dynamic stability of the protective mechanism, but also indirectly improves its sealing performance. Under long-term use or high-speed operation, the door panel may experience slight displacement due to vibration, but the buffer component 300 can correct these displacements in time, ensuring that the sealing structure between the door panel assembly 200 and the protective body 100 is always in optimal condition, effectively preventing the intrusion of contaminants.

[0066] The top plate 130 is provided with a third protruding plate 132 and a fourth protruding plate 133, which are arranged opposite to each other along the width direction of the clearance opening 131; the two ends of the buffer member 300 are respectively fastened to the third protruding plate 132 and the fourth protruding plate 133, and the buffer member 300 is telescopically arranged along the length direction of the third protruding plate 132 and the fourth protruding plate 133.

[0067] The installation of the buffer component 300 on the top plate 130 can effectively absorb vibration energy and reduce vibration transmission during machine tool operation, especially when the machine tool performs high-speed or high-precision machining tasks. In addition, the vibration reduction characteristics of the buffer component 300 can also significantly reduce noise caused by vibration, creating a quieter machining environment.

[0068] By combining the buffer component 300 with the third protruding plate 132 and the fourth protruding plate 133, it is not only possible to ensure that the sealing performance of the clearance opening 131 is not affected when the workpiece passes through, but also to automatically adjust before and after the workpiece is transferred, ensuring that the seal around the clearance opening 131 always maintains consistency and effectiveness, and avoiding seal failure caused by the entry and exit of the workpiece.

[0069] The buffer component 300 is provided with a first slot and a second slot. A third protruding plate 132 is inserted into the first slot, and a fourth protruding plate 133 is inserted into the second slot. A first elastic seal is provided on the third protruding plate 132, and the groove wall of the first slot is in contact with the first elastic seal. A second elastic seal is provided on the fourth protruding plate 133, and the groove wall of the second slot is in contact with the second elastic seal.

[0070] The precise fit between the third protruding plate 132 and the fourth protruding plate 133 and the first and second slots on the buffer component 300, along with the use of elastic seals, greatly enhances the sealing performance of the protective mechanism. This effectively prevents the penetration of contaminants such as cutting fluid, oil mist, and dust, protecting the precision components inside the machine tool and extending its service life and maintenance cycle.

[0071] This application also provides a processing device, including a protective mechanism and a workpiece to be processed, wherein the workpiece to be processed is disposed within the protective mechanism, and the protective mechanism is the same as the one described in the above embodiment.

[0072] The workpiece to be processed includes a spindle hydraulic station 410, a temperature control system 420, a water chiller 430, a chip conveyor 440, an operation panel 450, and an oil mist collector 460. First, the protective mechanism of this application is assembled onto the processing equipment, forming a protective shell around the main working area of ​​the equipment. This protective shell is composed of modular components such as a top plate, side plates, a front door, and a rear sealing plate. The components are sealed with a double-layer sealing structure (such as the cooperation between the first and second sealing parts) and a quick-release design, ensuring excellent sealing performance and convenient maintenance.

[0073] Inside the protective mechanism, key components such as the spindle hydraulic station 410, temperature control system 420, water chiller 430, chip conveyor 440, control panel 450, and oil mist collector 460 are rationally arranged. The spindle hydraulic station 410 provides power to the equipment; the temperature control system 420 and water chiller 430 control the operating temperature; the chip conveyor 440 cleans up metal chips generated during processing; the control panel 450 allows operators to monitor and control equipment operation; and the oil mist collector 460 captures and filters oil mist generated during processing, reducing air pollution.

[0074] By integrating the workpieces into the protective structure, an integrated protection system for the processing equipment is achieved. This design ensures that each workpiece operates within its specific, independent protective space, effectively preventing cross-contamination of contaminants, reducing interference between internal components, and improving the stability and efficiency of each functional unit.

[0075] The modular design of each workpiece allows for independent installation and maintenance without affecting the normal operation of other components. For example, when maintenance or replacement of the chip conveyor 440 is required, the relevant parts can be removed individually without disassembling the entire protective mechanism or equipment, greatly saving maintenance time and improving production efficiency.

[0076] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0077] The protective mechanism provided in this application includes a protective body 100, a door panel assembly 200, and a buffer component 300. The door panel assembly 200 includes a first door panel 210 and a second door panel 220. The first door panel 210 is provided with a first sealing part 230, and the second door panel 220 is provided with a second sealing part 240. The first sealing part 230 and the second sealing part 240 are interlocked to keep the first door panel 210 and the second door panel 220 in a closed position. The buffer component 300 is disposed on the protective body 100, and at least a portion of the buffer component 300 is retractable. The interlocking between the first sealing part 230 and the second sealing part 240 can still effectively prevent the penetration of cutting fluid, metal chips, dust, or oil mist. The addition of the buffer component 300, especially the retractable design on the protective body 100, effectively improves the vibration and noise problems of the protective cover under high-speed machining conditions. The buffer component 300 can provide flexible support and compensation when the machine tool is moving, absorb some of the vibration energy, reduce the transmission of vibration to the inside of the protective structure, avoid the possibility of the screws at the connection points loosening due to vibration, and thus enhance the structural stability and sealing reliability of the entire protective system.
