[0002] A vertical machining center is a machining center in which the spindle axis is set perpendicular to the worktable. It is mainly used to process complex parts such as plates, discs, molds and small shells. However, this type of equipment will produce large up and down vibrations during the machining process, which will not only produce large noise and cause sound pollution, affecting the machining accuracy and device stability, but also long-term vibration will damage the internal parts of the vertical machining center and reduce its service life. In order to solve these problems, a shock-absorbing and protective device for a vertical machining center has been designed. The main goal of this device is to reduce the vibration generated by the vertical machining center during the machining process, thereby reducing noise, improving machining accuracy and device stability, and extending the service life of the equipment. This shock-absorbing and protective device may use a variety of technologies to achieve its goals, such as using shock-absorbing materials, designing a reasonable shock-absorbing structure, and installing shock absorbers.

[0028] Embodiment 1:

[0029] A shock-absorbing protective device for a vertical machining center comprises a machining center base 1 and a shock-absorbing base 2, a plurality of support rods 3 are fixedly arranged in a matrix arrangement on the shock-absorbing base 2, a limited position block 4 is fixedly arranged on the support rod 3, a support platform 5 is movably sleeved on the support rod 3, the support platform 5 and the shock-absorbing base 2, and the limited position block 4 and the support platform 5 are fixedly connected by shock-absorbing springs 6, a fixed baffle 7 is fixedly arranged around the support platform 5, the machining center base 1 is arranged on the support platform 5, and the shock-absorbing base 2 and the support platform 5 are made of wear-resistant and non-slip materials;

[0030] In this embodiment, the shock-absorbing base 2 can play a certain shock-absorbing role. It is made of wear-resistant and non-slip materials to improve the service life of the device. The support rod 3 plays a role of limiting and guiding. The support platform 5 is used to support the machining center base 1. The limit block 4 can limit the support platform 5. The shock-absorbing spring 6 can support and tighten the support platform 5, so that the support platform 5 can be shock-absorbing and buffered under the action of the shock-absorbing springs 6 on the upper and lower sides when vibrating. The fixed baffle 7 can support and fix the shock-absorbing base 2 and the clamping plate 18 and other structures, and also provides installation space;

[0031] A vertical shock absorbing component, which is arranged on the shock absorbing base 2 and is used for vertically absorbing and buffering the base 1 of the machining center;

[0032] A horizontal shock absorbing component is arranged on the shock absorbing base 2 and is used for shock absorbing and buffering the machining center base 1 in the horizontal direction.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the vertical shock absorbing assembly, the vertical shock absorbing assembly includes a mounting groove 8 arranged in a matrix and opened on the shock absorbing base 2, a guide rod 9 is fixedly arranged in the mounting groove 8, a moving block 10 is movably sleeved on the guide rod 9, the moving block 10 is fixedly connected to the fixed baffle 7 by a second shock absorbing spring 11, a shock absorbing plate 12 is fixedly arranged at the bottom of the support platform 5, the shock absorbing plate 12 and the moving block 10 are rotatably connected by a shock absorbing rod 13, the shock absorbing rod 13 and the shock absorbing plate 12 and the moving block 10 are movably hinged, the support platform 5 and the shock absorbing base 2 are fixedly connected by a shock absorbing damping 14 and a high-pressure spring 15, the high-pressure spring 15 is sleeved on the shock absorbing damping 14, when the support platform 5 is in the initial position, the upper and lower shock absorbing springs 6 are the same length, and the moving block 10 is in the middle position of the mounting groove 8;

[0035] In this embodiment, the moving block 10 can move in the installation groove 8. When the moving block 10 moves, it will drive the second shock-absorbing spring 11 to expand and contract. When the supporting platform 5 vibrates, the vibration will be transmitted to the shock-absorbing plate 12 and the shock-absorbing rod 13, so that the shock-absorbing rod 13 can drive the moving block 10 to move under the action of the vibration. At this time, the second shock-absorbing spring 11 is compressed and will continue to extend under the action of its own elastic force, thereby offsetting the vibration. The moving block 10 and the shock-absorbing rod 13 arranged in a matrix array can enable the supporting platform 5 to receive a comprehensive shock-absorbing effect. The high-pressure spring 15 and the shock-absorbing damping 14 can support the supporting platform 5 while reducing shock and buffering it.

[0036] Embodiment three:

[0037] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the horizontal shock absorbing assembly, the horizontal shock absorbing assembly includes a plurality of lifting grooves 16 arranged in a rectangular array on the fixed baffle 7, a lifting block 17 is movably arranged in the lifting groove 16, the bottom of the lifting block 17 is fixedly connected to the support platform 5, a clamping plate 18 is arranged on the support platform 5, the clamping plate 18 and the lifting block 17 are fixedly connected by a micro spring 19 and a second shock absorbing damper 20, the clamping plate 18 is in movably contact with the base 1 of the vertical machining center, and an anti-slip pad 21 is fixedly arranged on the surface of the clamping plate 18;

[0038] In this embodiment, the lifting block 17 can be lifted and lowered in the lifting groove 16. When the supporting platform 5 vibrates, it will drive the lifting block 17 to be lifted and lowered in the lifting groove 16, so that the clamping plate 18 on the lifting block 17 can always remain roughly flush with the vertical machining center base 1 on the supporting platform 5, ensuring the clamping strength and tightness. At the same time, the micro spring 19 and the second shock-absorbing damper 20 can damp and buffer the vibration transmitted from the clamping plate 18. The anti-slip pad 21 is made of rubber material to ensure stable clamping and can also play a certain role in buffering vibration.

[0039] The shock absorbing damper 14 and the second shock absorbing damper 20 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art, and the specifications and models of the shock absorbing damper 14 and the second shock absorbing damper 20 are well known to those skilled in the art and will not be described in detail here.

[0040] Working principle: When the vertical machining center needs to be shock-proofed, the operator can first push the clamping plate 18 outward, then place the vertical machining center base 1 on the supporting platform 5, and then use the clamping plate 18 to clamp and fix the vertical machining center base 1;

[0041] When the vertical machining center is working, the vibration is transmitted to the support platform 5 through the vertical machining center base 1. The vibration on the support platform 5 can be initially damped and buffered under the action of the shock-absorbing spring 6. For the vibration in the vertical direction, the high-pressure spring 15 and the shock-absorbing damping 14 can damp and buffer the vibration. At the same time, when the vibration is transmitted to the shock-absorbing plate 12 and the shock-absorbing rod 13, the shock-absorbing rod 13 can drive the moving block 10 to move under the action of the vibration. At this time, the second shock-absorbing spring 11 is compressed by force and will continue to extend under the action of its own elastic force, so as to offset the vibration. The moving block 10 and the shock-absorbing rod 13 arranged in the matrix array can make the support platform 5 have a comprehensive shock-absorbing effect;

[0042] For horizontal vibrations, the anti-slip pad 21 can play a certain buffering role. At the same time, the micro spring 19 and the second shock-absorbing damper 20 can reduce and buffer the vibrations transmitted from the clamping plate 18. Moreover, under the action of the lifting groove 16 and the lifting block 17, the clamping plate 18 can always be kept roughly level with the base 1 of the vertical machining center, so that the shock-absorbing effect and the clamping effect are better.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
