[0029] Embodiment 1

[0030] Combination Figures 1 to 5 , a shock-absorbing base for a CNC machine tool, comprising a support base 1, a buffer mechanism 4 is arranged inside the support base 1, a support platform 2 is arranged on the top of the buffer mechanism 4, and a clamping mechanism 3 is arranged inside the support platform 2;

[0031] The clamping mechanism 3 includes a threaded rod 31, which is rotatably connected to the inner wall of the support platform 2, and a gear 32 is fixedly connected to the outer wall of the threaded rod 31. The outer ring of the gear 32 is meshed with a gear 2 33, and the inner ring of the gear 2 33 is fixedly connected to a worm 34. The outer wall of the worm 34 is meshed with a worm wheel 35, and the inner ring of the worm wheel 35 is fixedly connected to a threaded rod 2 36. The bottom of the inner wall of the support platform 2 is respectively fixedly connected to a support block 1 37 and a support block 2 38, and the outer walls of the threaded rod 2 36 and the threaded rod 1 31 are both threadedly connected to a threaded plate 39, the top of the threaded plate 39 is fixedly connected to a connecting column 301, and the top of the connecting column 301 is fixedly connected to a clamping plate 302.

[0032] Furthermore, a long opening is provided on the top of the support platform 2, and the connecting column 301 passes through the long opening and moves, so that the connecting column 301 can move through the long opening.

[0033] Furthermore, two threaded rods 36 are provided, and the outer wall threads of the two threaded rods 36 are in opposite directions, and the outer wall threads of the two ends of the threaded rod 1 31 are in opposite directions, so that the rotational motion of the threaded rods 36 and the threaded rod 1 31 can be converted into the linear motion of the corresponding threaded plate 39, thereby achieving the purpose of stable limit clamping.

[0034] Furthermore, the second threaded rod 36 is rotatably connected to the inside of the first support block 37 , and one end of the second threaded rod 36 away from the first support block 37 is rotatably connected to the inner wall of the support platform 2 , which can provide stable support for the second threaded rod 36 .

[0035] Furthermore, the threaded rod 31 passes through the right side of the support platform 2 and rotates, and the right end of the threaded rod 31 is fixedly connected to a hand wheel, so that the threaded rod 31 can be rotated by shaking the hand wheel.

[0036] Furthermore, the worm 34 is rotatably connected to the inside of the second support block 38, and the threaded plate 39 is slidably connected to the inner wall of the support platform 2, so that the threaded plate 39 can move stably.

[0037] Embodiment 2

[0038] See also Figures 1 to 5 On the basis of the first embodiment, the buffer mechanism 4 further comprises a fixed box 41, the fixed box 41 is fixedly connected to the bottom of the support platform 2, a spring 42 is fixedly connected to the top of the inner wall of the fixed box 41, a pressure plate 43 is fixedly connected to the bottom of the spring 42, and a support column 44 is fixedly connected to the bottom of the pressure plate 43, which can achieve the purpose of shock absorption for the CNC machine tool.

[0039] Furthermore, the support column 44 is fixedly connected to the bottom of the inner wall of the support seat 1, and a through hole is opened at the bottom of the fixed box 41. The support column 44 passes through the through hole, and the pressure plate 43 is slidably connected to the inner wall of the fixed box 41, so that the pressure plate 43 can move stably to compress the spring 42.

[0040] In actual operation, when the device is used, the staff first places the CNC machine tool on the top of the support platform 2, which can provide preliminary support and limit for it, and then shakes the hand wheel to drive the threaded rod 1 31 to rotate, so that the threaded rod 1 31 can drive the gear 1 32 to rotate, and the gear 1 32 drives the threaded rod 2 36 to rotate through the gear 2 33, the worm 34 and the worm wheel 35 in sequence, thereby making the threaded rod 1 31 and the threaded rod 2 36 rotate synchronously, and the support platform 2 can limit the threaded plate 39, so that The rotational motion of the threaded rod 1 31 and the threaded rod 2 36 is converted into the linear motion of the corresponding threaded plate 39. Since the threads of the outer walls at both ends of the threaded rod 1 31 are in opposite directions, and the threads of the outer walls of the two threaded rods 2 36 are in opposite directions, the four threaded plates 39 drive the clamping plates 302 to move toward the direction of the CNC machine tool through the connecting column 301. Therefore, the CNC machine tool can be limited under the clamping effect of the clamping plates 302, so that the CNC machine tool will not shake or deviate during operation, thereby achieving good stability in use.

[0041] Then, during use, when the CNC machine tool shakes, it will push the fixed box 41 to descend. During the descent of the fixed box 41, the spring 42 can be compressed under the support of the pressure plate 43. At the same time, the pressure plate 43 can slide and rub on the inner wall of the fixed box 41, thereby converting the vibration force generated during the operation of the CNC machine tool into the elastic potential energy of the spring 42. At the same time, under the action of the elastic potential energy of the spring 42, the pressure plate 43 can be pushed to rub back and forth, thereby achieving the purpose of friction damping and shock reduction, further offsetting the vibration force generated by the CNC machine tool, and achieving good seismic resistance.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
