[0038] Reference Figures 1 to 3 As shown, the first embodiment of the utility model proposes a machine tool vibration reduction system, including: a base 100, a vibration reduction seat 200, a first vibration reduction assembly 300, a suspension seat 400 and a second vibration reduction assembly 500, the vibration reduction seat 200 is arranged above the base 100; the first vibration reduction assembly 300 is arranged between the base 100 and the vibration reduction seat 200, and connects the base 100 and the vibration reduction seat 200; the suspension seat 400 is arranged between the base 100 and the vibration reduction seat 200, and the suspension seat 400 is provided with an avoidance hole for avoiding the first vibration reduction assembly 300; the second vibration reduction assembly 500 is arranged between the vibration reduction seat 200 and the suspension seat 400, and is connected to the vibration reduction seat 200 and the suspension seat 400.

[0039] In this embodiment, the base 100 is a rectangular steel plate, and the outline of the base 100 is larger than the outline of the bottom of the machine tool so as to support the machine tool.

[0040] The vibration damping seat 200 is also a rectangular steel plate. The vibration damping seat 200 directly supports the machine tool and buffers and reduces vibrations through the first vibration damping assembly 300. When the vibration of the machine tool is transmitted to the vibration damping seat, the first vibration reduction will be performed through the first vibration damping assembly 300, and the vibration reduction direction is mainly in the vertical direction.

[0041] The suspension seat 400 is also in the shape of a rectangular parallelepiped, and its material is also selected from low-cost materials with a density close to that of steel. The suspension seat 400 is arranged between the shock-absorbing seat and the base 100, reducing the interval between the shock-absorbing seat 200 and the base 100, so as to make full use of the interval. The suspension seat 400 is connected to the shock-absorbing seat 200 through the second shock-absorbing assembly 500. When the vibration of the machine tool is transmitted to the shock-absorbing seat 200, part of the vibration is transmitted to the suspension seat 400 through the second shock-absorbing assembly 500. The suspension seat 400 generates vibration in the vertical direction through the second shock-absorbing assembly 500, and the second shock-absorbing is realized through the second vibration assembly, and the direction of shock-absorbing is also in the vertical direction; and the suspension seat 400 is suspended in the second vibration assembly, and the suspension seat 400 can also consume the vibration energy transmitted by the machine tool through its own vibration.

[0042] It is worth understanding that the machine tool is placed above the vibration damping seat 200. When the vibration is transmitted to the vibration damping seat 200, the vibration damping seat 200 eliminates part of the vibration force through the first vibration damping assembly 300, and the other part of the vibration force will be transmitted to the suspension seat 400 through the second vibration damping assembly 500. The vibration force is eliminated by the second vibration damping assembly 500, and the suspension seat 400 can also consume a certain amount of vibration energy through vibration to achieve vibration reduction, thereby achieving triple vibration reduction, so as to improve the vibration reduction effect of the machine tool, improve machining accuracy, and reduce operating noise.

[0043] Reference Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the first vibration damping assembly 300 includes a first vibration damping member 310 . The first vibration damping member 310 is disposed between the base 100 and the vibration damping seat 200 , and connects the base 100 and the vibration damping seat 200 .

[0044] It is worth to understand that the first vibration damping assembly 300 realizes the vibration damping function in the vertical direction through the first vibration damping member 310 to reduce the vibration received by the vibration damping seat 200 .

[0045] In this embodiment, the first vibration damping assembly 300 includes a plurality of first vibration damping members 310, and the plurality of first vibration damping members 310 are evenly distributed between the base 100 and the vibration damping seat 200. The even distribution of the plurality of first vibration damping members 310 makes the force on the first vibration damping members 310 more even, and can evenly distribute the vibration force applied by the machine tool, thereby improving the vibration damping effect. Among them, the first vibration damping member 310 is a spring damping shock absorber.

[0046] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the base 100 is provided with a surrounding wall 110 surrounding the vibration damping seat 200, and the first vibration damping assembly 300 includes a second vibration damping member 320, which is provided between the vibration damping seat 200 and the surrounding wall 110, and connects the vibration damping seat 200 and the surrounding wall 110.

[0047] It is worth understanding that by arranging the second vibration damping member 320 between the surrounding wall 110 and the side surface of the vibration damping seat 200 to dampen the vibration of the vibration damping seat 200 in the horizontal direction, the vibration damping seat 200 is also subjected to the vibration damping force in the horizontal direction, thereby enabling the vibration damping seat 200 to perform omnidirectional vibration damping.

[0048] In this embodiment, the second vibration damper 320 is also a spring damper, and the number of the second vibration damper 320 is also multiple, and the multiple second vibration dampers 320 are evenly distributed around the vibration damping seat 200. Among them, the second vibration damper 320 is hingedly connected to the vibration damping seat 200, and the second vibration damper 320 is also hingedly connected to the surrounding wall 110, so as to avoid the second vibration damper 320 and the vibration damping seat 200 being rigidly connected to affect the vibration of the vibration damping seat 200 in the vertical direction. At the same time, the second vibration damper 320 can also increase a certain damping force when the vibration damping seat 200 vibrates in the vertical direction.

[0049] Reference Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the second vibration damping assembly 500 includes a third vibration damping member 510 , which is disposed between the vibration damping seat 200 and the suspension seat 400 , and connects the suspension seat 400 and the vibration damping seat 200 .

[0050] It is worth to understand that the second vibration damping assembly 500 realizes the vibration damping function in the vertical direction through the third vibration damping member 510 to reduce the vibration received by the vibration damping seat 200 .

[0051] In this embodiment, the second vibration damping assembly 500 includes a plurality of third vibration damping members 510, and the plurality of third vibration damping members 510 are evenly distributed between the suspension seat 400 and the vibration damping seat 200. The even distribution of the plurality of third vibration damping members 510 makes the force on the third vibration damping members 510 more even, and can evenly distribute the vibration force applied by the machine tool, thereby improving the vibration damping effect. Among them, the third vibration damping member 510 is a spring damping shock absorber.

[0052] Reference Figure 3 As shown, in some specific embodiments of the present invention, the base 100 is provided with a surrounding wall 110 surrounding the vibration damping seat 200, and the second vibration damping assembly 500 includes a fourth vibration damping member 520, which is provided between the suspension seat 400 and the surrounding wall 110 and connects the suspension seat 400 and the surrounding wall 110.

[0053] It is worth understanding that by arranging the fourth vibration damper 520 between the surrounding wall 110 and the side of the suspension seat 400 to dampen the vibration of the suspension seat 400 in the horizontal direction, the suspension seat 400 is also subjected to the damping force in the horizontal direction, thereby enabling the suspension seat 400 to perform omnidirectional vibration damping.

[0054] In this embodiment, the fourth vibration damper 520 is also a spring damper, and the number of the fourth vibration damper 520 is also multiple, and the multiple fourth vibration dampers 520 are evenly distributed around the suspension seat 400. The fourth vibration damper 520 is hingedly connected to the suspension seat 400, and the fourth vibration damper 520 is also hingedly connected to the surrounding wall 110, so as to avoid the fourth vibration damper 520 being rigidly connected to the suspension seat 400 to affect the vibration of the suspension seat 400 in the vertical direction. At the same time, the fourth vibration damper 520 can also increase a certain damping force when the suspension seat 400 vibrates in the vertical direction.

[0055] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the base 100 is provided with a surrounding wall 110 surrounding the vibration damping seat 200, and the vibration damping seat 200 includes a main body 210 and a covering portion 220 connected to the top of the main body 210, the main body 210 is connected to the first vibration damping assembly 300 and the second vibration damping assembly 500, and the covering portion 220 is covered on the top of the surrounding wall 110.

[0056] It is worth to understand that the covering portion 220 covers the top of the surrounding wall 110 to seal the first vibration damping assembly 300 and the second vibration damping assembly 500 in the surrounding wall 110 , thereby reducing the possibility of machining debris entering the surrounding wall 110 .

[0057] Specifically, the covering portion 220 includes a first plate portion and a second plate portion connected to the first plate portion, wherein the first plate portion is connected to the top of the main body portion 210 and completely covers the top of the surrounding wall 110, wherein the first plate portion and the top of the surrounding wall 110 are spaced apart to allow the vibration damping seat 200 to smoothly perform vibration damping, and a second plate portion extending toward the base 100 is arranged at the edge of the first plate portion to block the spacing space between the first plate portion and the top of the surrounding wall 110 to reduce the possibility of debris entering.

[0058] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the base 100 includes a bottom plate 130 and a surrounding wall 110 connected to the top surface of the bottom plate 130, the surrounding wall 110 surrounds the vibration damping seat 200, and the surrounding wall 110 and the bottom plate 130 together form a receiving groove 120, which is used to hold liquid.

[0059] It is worth understanding that, by containing liquid in the surrounding wall 110, when the suspension seat 400 vibrates in the vertical direction, the suspension seat 400 is subjected to the viscosity of the liquid, so that the suspension seat 400 can perform a third vibration reduction on the vibration reduction seat 200 in the vertical direction, and when the suspension seat 400 is subjected to the viscosity, it will further pull the second vibration reduction assembly 500 for vibration reduction to improve the vibration reduction effect.

[0060] In this embodiment, the liquid in the receiving tank 120 should cover the vibration damping seat 200 and not exceed the bottom surface of the suspension seat 400. In addition, because the existence of the suspension seat 400 can occupy a larger space in the receiving tank 120, the amount of liquid used can be effectively reduced when using the damping liquid, which can effectively reduce the cost of use.

[0061] Among them, the elastic force of the second vibration damping assembly 500 is smaller than the elastic force of the first vibration damping assembly 300. When the vibration of the machine tool is transmitted to the second vibration damping assembly 500, the second vibration damping assembly 500 has a longer vibration amplitude, so that the suspension seat 400 can have a higher vibration amplitude and fully contact with the damping fluid to achieve vibration reduction.

[0062] In addition, the presence of the covering portion 220 can also prevent foreign matter from entering the containing tank 120 and contaminating the damping fluid, thereby improving the service life and use effect of the damping fluid.

[0063] In some specific embodiments of the present invention, the surrounding wall 110 is provided with an observation window for observing the liquid in the containing tank 120 .

[0064] It is worth understanding that the liquid level in the receiving tank 120 can be observed through the observation window so as to timely understand the liquid level in the receiving tank 120. When the liquid level drops or when there are too many impurities in the damping liquid, the user can actively add liquid and know the adding position. A liquid adding port that can be opened or closed is provided at the top of the surrounding wall 110 to facilitate adding liquid.

[0065] The second embodiment of the utility model provides a machine tool, comprising: the machine tool vibration reduction system of the first embodiment. It is worth understanding that the machine tool of the second embodiment uses the machine tool vibration reduction system of the first embodiment, which can greatly improve the vibration reduction effect of the machine tool, reduce the impact of vibration on the machine tool itself, improve processing accuracy, and reduce operating noise.

[0066] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
