Description

Technical Field

[0001] This invention relates to the field of five-axis linkage machine tool technology, specifically a multi-stage vibration isolation system for a five-axis linkage machine tool base. Background Technology

[0002] In aerospace, automobile manufacturing, mold processing and other fields, five-axis CNC machine tools are responsible for the precision machining of complex curved parts. The machining accuracy requirements are at the micron level or even higher. However, external environmental vibrations such as equipment operation, foundation settlement, traffic interference and internal cutting force fluctuations can significantly affect the machining stability.

[0003] Common vibration reduction methods in existing technologies include rubber vibration isolation pads, which absorb vibration energy through elastic materials, are low in cost and easy to install, but have poor attenuation effect on high-frequency vibrations; air spring vibration isolation systems utilize the elastic properties of compressed air to achieve vibration reduction, effectively isolating low-frequency vibrations, but the system is complex and requires continuous air supply; hydraulic dampers dissipate vibration energy through the viscous resistance of liquids, which have a certain effect on broadband vibrations, but there is a risk of oil leakage and high temperature sensitivity; and combined vibration isolation platforms combine a composite structure of rubber and metal springs, which can take into account both low-frequency and high-frequency vibration reduction, but the vibration reduction efficiency is uneven across different frequency bands. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-stage vibration isolation system for a five-axis linkage machine tool base. This system solves the problems of existing technologies, such as the easy aging of rubber vibration isolation pads and significant changes in stiffness with temperature, the need for an additional air source and slow response speed of air spring systems, high maintenance costs and environmental pollution risks of hydraulic dampers, and the difficulty in achieving optimal vibration reduction across the entire frequency band due to the structural coupling of combined platforms.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage vibration isolation system for a five-axis linkage machine tool base, comprising a machine base, a milling frame disposed on the upper surface of the machine base, a U-shaped block fixedly connected inside the machine base, a motor fixedly connected to the outer wall of the U-shaped block, the output end of the motor rotatably connected to the inside of the U-shaped block and fixedly connected to a worm gear, the outer wall of the worm gear rotatably connected to the inside of the U-shaped block, a worm wheel meshing with the tooth end of the worm gear, a rotating shaft fixedly connected to the inner wall of the worm wheel, a bevel gear fixedly connected to the outer wall of the rotating shaft, a spur gear fixedly connected to the outer wall of the rotating shaft, a support block fixedly connected to the outer wall of the machine base, the outer wall of the rotating shaft rotatably connected to the inside of the support block, a T-shaped through groove and a limit groove provided inside the machine base, a primary vibration isolation mechanism provided on the outer wall of the machine base, and a secondary vibration isolation mechanism provided at the tooth end of the spur gear.

[0009] Preferably, the primary vibration isolation mechanism also includes a side plate, the outer wall of which is fixedly connected to the outer wall of the second U-shaped block, and the outer wall of the side plate is provided with an inclined groove.

[0010] Preferably, the primary vibration isolation mechanism further includes a second U-shaped plate, the outer wall of which is fixedly connected to the outer wall of the internally threaded slider, a second guide post is fixedly connected to the inside of the second U-shaped plate, a third slider is slidably connected to the outer wall of the second guide post, a connecting block is fixedly connected to the outer wall of the third slider, a sliding column is fixedly connected to the outer wall of the connecting block, the outer wall of the sliding column is slidably connected to the inner wall of the inclined groove, an L-shaped support leg is fixedly connected to the upper surface of the third slider, and a support plate is fixedly connected to the lower surface of the L-shaped support leg.

[0011] Preferably, the primary vibration isolation mechanism further includes a damper, one end of which is fixedly connected to the upper surface of the support plate, and the other end of which is fixedly connected to the outer wall of the L-shaped support leg.

[0012] Preferably, the secondary vibration isolation mechanism includes a rack, the tooth ends of which mesh with the tooth ends of a spur gear, a sliding plate is fixedly connected to the upper surface of the rack, the outer wall of the sliding plate is slidably connected to the inner wall of a T-shaped through groove, a limiting post is fixedly connected to the outer wall of the sliding plate, and the outer wall of the limiting post is slidably connected to the inner wall of the limiting groove.

[0013] Preferably, the secondary vibration isolation mechanism further includes a rotating column, the outer wall of which is rotatably connected to the inside of the sliding plate, a circular block is fixedly connected to the outer wall of the rotating column, the outer wall of the circular block is provided with a slot, and a support frame is fixedly connected to the outer wall of the rotating column.

[0014] Preferably, the secondary vibration isolation mechanism further includes a fixing block, the lower surface of which is fixedly connected to the upper surface of the sliding plate, a locking post is slidably connected inside the fixing block, the outer wall of the locking post is slidably connected to the inner wall of the locking groove, a pull block is fixedly connected to the outer wall of the locking post, a limit block is fixedly connected to the outer wall of the locking post, and a spring is slidably connected to the outer wall of the locking post.

[0015] Preferably, one end of the spring is fixedly connected to the outer wall of the fixing block, and the other end of the spring is fixedly connected to the end of the limiting block near the fixing block.

[0016] Working principle: When using the milling machine, the motor is started, which causes the worm gear to rotate, which in turn causes the worm wheel to rotate. The rotation of the worm wheel drives the first bevel gear to rotate through the rotating shaft. During the rotation of the first bevel gear, the threaded rod rotates inside the second U-shaped block through the second bevel gear, causing the internal threaded slider to move downward and slide on the outer wall of the first guide post. During the downward movement of the internal threaded slider, the second U-shaped plate moves downward, which in turn causes the connecting block to drive the sliding column to slide in the inner wall of the inclined groove opened on the outer wall of the side plate. During the sliding of the sliding column in the inclined groove, the sliding column, through the connecting block, causes the L-shaped support leg to drive the third slider to slide outward and downward on the outer wall of the second guide post. The L-shaped support leg drives the support plate to contact the ground.

[0017] During the rotation of the rotating shaft, the rotating shaft also drives the spur gear to rotate. The rotation of the spur gear drives the sliding plate to move outward and slide on the inner wall of the T-shaped through groove through the rack. During the outward movement of the sliding plate and its sliding on the inner wall of the T-shaped through groove, it also drives the limiting post to move outward and slide on the inner wall of the limiting groove. The outward movement of the sliding plate drives the rotating post to move outward, and the outward movement of the rotating post drives the support frame to move outward. When the limiting post slides to the limit of the inner wall of the limiting groove, the pull block can be pulled to make the locking post move inward and slide inside the fixed block and slide out from the inner wall of the locking groove. Then the support frame is rotated 90 degrees. After the rotation, the pull block is no longer pulled, which causes the spring in the contracted state to rebound and reset. Through the limiting round block, the locking post is driven into the inner wall of the locking groove after adjustment. This is achieved by extending and rotating the support frame.

[0018] This invention provides a multi-stage vibration isolation system for a five-axis linkage machine tool base. It has the following beneficial effects: 1. In the primary vibration isolation mechanism, the present invention dissipates vibration energy through a damper to reduce vibration amplitude and suppress resonance. The L-shaped support legs and support plates are used to expand the support area and distribute the load evenly, thereby enhancing structural stability. At the same time, it works in conjunction with the secondary vibration isolation mechanism to form a multi-level vibration isolation system, suppressing vibration in the middle and ensuring accuracy transmission. The two work together to achieve all-round vibration isolation, optimize system performance for vibrations of different frequencies and directions, and improve processing quality and efficiency.

[0019] 2. This invention uses mechanical linkage control to extend the primary and secondary vibration isolation mechanisms when the milling frame starts processing, making contact with the ground or support structure to construct a complete vibration isolation system. When the machine stops, the mechanisms retract to restore the compact form of the machine tool, achieving efficient operation of "extending when needed and retracting when not needed". At the same time, it avoids the obstruction of machine tool movement or positioning by avoidable fixation.

[0020] 3. By extending and rotating the support frame, and by moving and rotating the sliding column outward, the support changes the center of gravity and support range of the milling head. When the milling head encounters large external forces such as accidental collisions or instantaneous strong cutting force impacts, it can provide a greater anti-overturning moment, reduce the risk of machine tool overturning, and ensure that the machine tool can operate stably under various working conditions.

Detailed Implementation

[0023] The technical solution of the present invention will now be clearly and completely described 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.

[0024] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a multi-stage vibration isolation system for a five-axis linkage machine tool base, including a machine base 1. A milling frame 2 is provided on the upper surface of the machine base 1. A U-shaped block 3 is fixedly connected inside the machine base 1. A motor 4 is fixedly connected to the outer wall of the U-shaped block 3. The output end of the motor 4 is rotatably connected to the inside of the U-shaped block 3 and fixedly connected to a worm gear 5. The outer wall of the worm gear 5 is rotatably connected to the inside of the U-shaped block 3. A worm wheel 6 is meshed with the tooth end of the worm gear 5. A rotating shaft 7 is fixedly connected to the inner wall of the worm wheel 6. A bevel gear 10 is fixedly connected to the outer wall of the rotating shaft 7. A spur gear 9 is fixedly connected to the outer wall of the rotating shaft 7. A support block 8 is fixedly connected to the outer wall of the machine base 1. The outer wall of the rotating shaft 7 is rotatably connected to the inside of the support block 8. A T-shaped through groove 11 is provided inside the machine base 1. A limit groove 12 is provided inside the machine base 1. A primary vibration isolation mechanism is provided on the outer wall of the machine base 1. A secondary vibration isolation mechanism is provided on the tooth end of the spur gear 9.

[0025] Specifically, during operation, motor 4 needs to be started. Starting motor 4 causes its output end to rotate, connecting to the inside of U-shaped block 3 and driving worm gear 5 to rotate. This rotation of worm gear 5 within U-shaped block 3 then drives the meshing worm wheel 6 to rotate. The rotation of worm wheel 6, via rotating shaft 7, drives bevel gear 10 to rotate. The rotation of bevel gear 10 activates the primary vibration isolation mechanism. During the rotation of rotating shaft 7, it also drives spur gear 9 to rotate, activating the secondary vibration isolation mechanism. Through mechanical linkage control, the primary and secondary vibration isolation mechanisms extend when the milling frame 2 starts machining, contacting the ground or supporting structure to form a complete vibration isolation system. When the machine stops, they retract, restoring the machine tool to its compact form, achieving efficient operation of "extend when needed, retract when not needed." This also avoids obstruction to machine tool movement or positioning by fixed components. No additional disassembly or installation of vibration isolation components is required, saving debugging time and improving machine tool efficiency. The primary vibration isolation mechanism is set on both sides of the machine tool, which expands the support area, buffers vibration, and adapts to complex working conditions to stabilize both sides. The secondary vibration isolation mechanism uses a movable and rotatable bracket in the middle to suppress vibration in the middle. The two work together to achieve all-round vibration isolation, optimize system performance for vibrations of different frequencies and directions, and improve processing quality and efficiency.

[0026] Please see the appendix Figure 1 - Appendix Figure 7 The primary vibration isolation mechanism includes a second U-shaped block 13, the outer wall of which is fixedly connected to the outer wall of the base 1. A guide post 14 is fixedly connected inside the second U-shaped block 13. An internally threaded slider 15 is slidably connected to the outer wall of the guide post 14. A threaded rod 16 is rotatably connected inside the second U-shaped block 13, and the outer wall of the threaded rod 16 is threadedly connected to the inside of the internally threaded slider 15. The primary vibration isolation mechanism also includes a second bevel gear 17, the inner wall of which is fixedly connected to the outer wall of the threaded rod 16. The tooth end of the second bevel gear 17 meshes with the tooth end of the first bevel gear 10. The primary vibration isolation mechanism also includes a second U-shaped plate 20, the outer wall of which is fixedly connected to the outer wall of the internally threaded slider 15. A second guide post 21 is fixedly connected inside the second U-shaped plate 20. A third slider 22 is slidably connected to the outer wall of the second guide post 21. A connecting block 23 is fixedly connected to the outer wall of the third slider 22. A sliding column 24 is fixedly connected to the outer wall of the connecting block 23. The outer wall of the sliding column 24 is slidably connected to the inner wall of the inclined groove 19. An L-shaped support leg 25 is fixedly connected to the upper surface of the third slider 22. A support plate 26 is fixedly connected to the lower surface of the L-shaped support leg 25. The primary vibration isolation mechanism also includes a damper 27, one end of which is fixedly connected to the upper surface of the support plate 26, and the other end of which is fixedly connected to the outer wall of the L-shaped support leg 25.

[0027] Specifically, during the use of the milling fixture 2, the motor 4 is started. The start of the motor 4 causes the worm gear 5 to rotate, which in turn causes the worm wheel 6 to rotate. The rotation of the worm wheel 6 drives the bevel gear 10 to rotate via the rotating shaft 7. During the rotation of the bevel gear 10, the threaded rod 16 is driven to rotate inside the U-shaped block 13 via the bevel gear 17, causing the internal threaded slider 15 to move downward and slide on the outer wall of the guide post 14. During the downward movement of the internal threaded slider 15, the U-shaped plate 20 is driven to move downward, which in turn causes the connecting block 23 to drive the sliding column 24 to slide in the inner wall of the inclined groove 19 opened on the outer wall of the side plate 18. During the sliding of the sliding column 24 in the inner wall of the inclined groove 19, the sliding column 24, through the connecting block 23, causes the L The L-shaped support leg 25 drives the slider 3 22 to slide outward and downward on the outer wall of the guide column 21. The L-shaped support leg 25 drives the support plate 26 to contact the ground. The outward movement increases the contact range between the machine base 1 and the ground, forming a wider support base and lowering the center of gravity of the milling frame 2. Especially when the milling frame 2 is milling at high speed or under dynamic load, it reduces the shaking or displacement caused by vibration. After contacting the ground downward, the support plate 26 distributes the weight of the machine base 1 and the milling frame 2 and the dynamic load during processing to a larger area, reducing local pressure. At the same time, when not in use, it can be retracted to its original state to avoid occupying the ground or surrounding space, which helps to reduce the overall size of the equipment and facilitates handling, installation and site planning.

[0028] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 6 and attached Figure 8 The secondary vibration isolation mechanism includes a rack 28, the tooth ends of which mesh with the tooth ends of a spur gear 9. A sliding plate 29 is fixedly connected to the upper surface of the rack 28. The outer wall of the sliding plate 29 is slidably connected to the inner wall of the T-shaped through groove 11. A limiting post 30 is fixedly connected to the outer wall of the sliding plate 29, and the outer wall of the limiting post 30 is slidably connected to the inner wall of the limiting groove 12. The secondary vibration isolation mechanism also includes a rotating post 31, the outer wall of which is rotatably connected to the inside of the sliding plate 29. A circular block 32 is fixedly connected to the outer wall of the rotating post 31, and a slot 33 is formed on the outer wall of the circular block 32. The outer wall is fixedly connected to a support frame 34; the secondary vibration isolation mechanism also includes a fixed block 35, the lower surface of the fixed block 35 is fixedly connected to the upper surface of the sliding plate 29, the inside of the fixed block 35 is slidably connected to a locking post 36, the outer wall of the locking post 36 is slidably connected to the inner wall of the locking groove 33, the outer wall of the locking post 36 is fixedly connected to a pull block 37, the outer wall of the locking post 36 is fixedly connected to a limiting round block 38, and the outer wall of the locking post 36 is slidably connected to a spring 39; one end of the spring 39 is fixedly connected to the outer wall of the fixed block 35, and the other end of the spring 39 is fixedly connected to the end of the limiting round block 38 near the fixed block 35.

[0029] Specifically, during the rotation of the rotating shaft 7, the rotating shaft 7 also drives the spur gear 9 to rotate. The rotation of the spur gear 9 drives the sliding plate 29 to move outward and slide against the inner wall of the T-shaped through groove 11 via the rack 28. During the outward movement of the sliding plate 29 against the inner wall of the T-shaped through groove 11, the limiting post 30 also moves outward and slides against the inner wall of the limiting groove 12. The outward movement of the sliding plate 29 drives the rotating post 31 to move outward, and the outward movement of the rotating post 31 drives the support frame 34 to move outward. When the limiting post 30 slides to the limit of the inner wall of the limiting groove 12, the pull block 37 can be pulled to cause the locking post 36 to move inward and slide against the fixed block 3. The support frame 34 is rotated 90 degrees after sliding out from the inner wall of the slot 33. After rotation, the pull block 37 is no longer pulled, which causes the spring 39 in the contracted state to rebound and reset. Through the limit block 38, the locking pin 36 is driven into the inner wall of the slot 33 after adjustment. By extending and rotating the support frame 34, and by moving and rotating the sliding pin 24 outward, the bracket changes the center of gravity position and support range of the milling frame 2. When the milling frame 2 encounters a large external force interference, such as an accidental collision or a sudden strong cutting force impact, it can provide a greater anti-overturning moment, reduce the risk of machine tool overturning, and ensure that the machine tool can operate stably under various working conditions.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
