In most cases, large-scale electromechanical equipment is placed directly on the ground, and its bottom is generally in direct contact with the ground, or a gasket is simply added under the tripod to prevent the machine tool from crushing and fracturing the ground. For machines that vibrate strongly during operation, simple damping pads will not play any substantial role.

Only use the vibration damping spring to vertically damp the mechanical equipment placed on the support plate , without considering that the mechanical equipment will tilt outward when placed on the support plate, resulting in poor stability of the mechanical equipment and affecting its normal use. 2. A sliding column is provided, and the sliding column passes through the upper adjustment plate and the supporting plate body. When the mechanical equipment placed on the supporting plate body is tilted due to uneven force on the supporting plate body, the sliding column will be bent or even broken. cause the damping device to fail.

作为优化，所述承重板下方还设置有安装板，所述第一压缩螺旋弹簧的上端与所述安装板的下表面固定连接；所述安装板上表面内凹形成凹槽，所述凹槽内固定连接有竖向设置的套筒，所述承重板下表面正对所述套筒固定连接有限位柱，所述限位柱可在所述套筒内滑动，所述套筒内竖向设置有第二压缩螺旋弹簧，所述第二压缩螺旋弹簧的下端固定连接在所述凹槽槽底表面上，上端套接在所述限位柱上，所述第二压缩螺旋弹簧原始长度大于所述套筒的高度。As an optimization, a mounting plate is also provided under the load-bearing plate, and the upper end of the first compression coil spring is fixedly connected to the lower surface of the mounting plate; the upper surface of the mounting plate is recessed to form a groove, and the groove A vertically arranged sleeve is fixedly connected inside, and the lower surface of the load-bearing plate is fixedly connected with a limit column facing the sleeve, and the limit column can slide in the sleeve, and the inside of the sleeve is vertically A second compression coil spring is provided. The lower end of the second compression coil spring is fixedly connected to the bottom surface of the groove, and the upper end is sleeved on the limit post. The original length of the second compression coil spring is greater than the height of the sleeve.
这样，承重板下方设置有安装板，安装板上表面内凹形成凹槽，凹槽内设置有套筒，承重板下表面正对套筒连接设置有限位柱，限位柱可沿套筒滑动，套筒内设置有第二压缩螺旋弹簧，第二压缩螺旋弹簧原始长度大于套筒的高度，以更好的发挥第二压缩螺旋弹簧的功能。机械设备放置在承重板上，在产生的竖向振幅较小时，可以压缩第二压缩螺旋弹簧，限位柱进入套筒内，以对机械设备产生一个缓冲作用，可以减小机械设备的振动，更好的提高整个装置的通用性。In this way, a mounting plate is arranged below the load-bearing plate, and the surface of the mounting plate is concave to form a groove, and a sleeve is arranged in the groove, and the lower surface of the load-bearing plate is directly connected to the sleeve to be provided with a limit column, and the limit column can slide along the sleeve , the sleeve is provided with a second compression coil spring, the original length of the second compression coil spring is greater than the height of the sleeve, so as to better play the function of the second compression coil spring.

The elastic block can be arranged in a hemispherical shape, and the hemispherical surface of the hemispherical shape is arranged towards the load-bearing plate, and the hemispherical flat surface is fixedly connected to the bottom surface of the groove, so that the elastic block can be better stressed. When the hemispherical elastic block begins to be stressed, the contact area between the upper end of the elastic block and the load-bearing plate is small, and the stored elastic potential energy is less, so the elastic block can produce a large deformation; later, the contact area between the elastic block and the load-bearing plate gradually increases. Larger, the elastic potential energy also increases gradually. At this time, a larger force is required to deform the elastic block, that is, the elastic block can withstand greater pressure, so the elastic block is set in the form of a hemispherical structure, which can better bear force , to better increase the stability of the entire device.
