Damping device for large machine tool

Abstract

The invention relates to damping structures of machine tools, in particular to a damping device for a large machine tool. The damping device is used for connection between the large machine tool and the ground, and comprises a machine tool supporting framework and a ground supporting framework. The machine tool supporting framework is arranged in the ground supporting framework. The machine tool is arranged in the machine tool supporting framework. An interlayer is arranged between the machine tool supporting framework and the ground supporting framework in a spaced manner. A plurality of supporting seats are arranged in the interlayer, damping springs are arranged between the tops of the supporting seats and the machine tool supporting framework, and damping springs are arranged between the bottoms of the supporting seats and the ground supporting framework. The interlayer is filled with foam aluminum materials. The springs are arranged in the interlayer as the damping structure, meanwhile, the interlayer is filled with the foam aluminum materials so that transmitted vibration mechanical energy can be quickly attenuated and absorbed, the good damping effect is achieved, and the service life of the machine tool is prolonged.

Description

technical field [0001] The invention relates to the field of shock absorbing structures of machine tools, in particular to a shock absorbing device for large machine tools. Background technique [0002] In the known technical field, machine tools such as knitting machinery and textile machinery will produce high-frequency transverse shock and longitudinal shock when they are working, so a shock absorber is needed to reduce the vibration of the machine. The shock absorber in the prior art often consists of a simple It is composed of springs, block rubber, etc. This technical solution can achieve a certain shock absorption effect in the case of a single transverse shock and longitudinal shock, but the vibration of machine tools such as knitting machinery and textile machinery is often combined vibration, so it leads to shock absorption. The effect is poor, not only the life of the shock absorber itself is short, but also the life of the machine tool is easily shortened. [00...

AI Technical Summary

Problems solved by technology

[0006] For example, the existing patent No. 201220093562.1 discloses a shock absorbing device, the device includes a housing on which a support plate is mounted, and the housing is filled with high-density micro-foamed poly The technical solution of amine grease material, through filling the above material in the shell, achieves the effect of damping vibration, but in the above design, there is still a step-by-step vibration force that is directly transmitted to the ground through the shell, which will cause certain damage to the machine tool and the ground

[0007] Another example is that the application number is 201410204043.1, which discloses a large-scale machine tool shock absorber, wherein a shock absorber is arranged between the machine tool support frame and the ground support frame, and the shock absorber is a spring, but in actual use, the machine tool The support frame will wobble in the ground support frame and its shock absorption effect is not ideal
