Detailed ways

The implementation process and implementation effects of the present utility model will be described in detail below in conjunction with the accompanying drawings. It should be understood that the examples are only to better illustrate the technical solution of the present utility model, not to limit the technical solution.

As shown in Figure 1, a new type of shock-absorbing foot pad for machine tools includes a pressure plate 4 and a base plate 6. The pressure plate 4 and the base plate 6 are relatively up and down and connected by a connecting device. Several springs 5 are arranged between the pressure plate 4 and the base plate 6. .

2 and 3, the connection device between the pressure plate 4 and the bottom plate 6 is specifically: more than two tension frames are arranged under the pressure plate. The pull frame 10, the left pull frame 7 and the right pull frame 10 are symmetrically arranged under the pressing plate 4 with one left and one right. In order to enhance the strength of the rack and facilitate installation, the rack is a three-dimensional rack formed by three steel plates perpendicularly intersecting each other, and the connecting holes are arranged on the steel plate parallel to the bottom plate. The base plate is provided with fixing bolts corresponding to the number and position of the pull frame, the left fixing bolt 9 and the right fixing bolt 12, and the left fixing bolt 9 and the right fixing bolt 12 pass through the connecting hole on the pulling frame and the The above-mentioned pull frame is connected by adjusting nuts, that is, the left adjusting nut 8 and the right adjusting nut 11. The adjusting nut can fix the bracket and the fixing bolt on the one hand, and on the other hand, can also fine-tune the distance between the pressing plate 4 and the base plate 6, so as to further ensure the balance of the machine tool arranged on the foot pad.

The lower surface of the pressing plate 4 is provided with bosses 3 corresponding to the number of springs 5 , the outer diameter of the boss 3 is less than or equal to the inner diameter of the springs 5 , and the upper surface of the bottom plate 6 is provided with a number corresponding to the number of springs 5 . The concave platform 13, the inner diameter of the concave platform 13 is greater than or equal to the outer diameter of the spring 5, the number and position of the convex platform 3 and the concave platform 13 are all in one-to-one correspondence, and they are respectively located at the two ends of the spring 5, that is One end of the spring located between the pressure plate 4 and the bottom plate 6 is nested with the boss 3, and the other end is nested with the concave platform 13, so that the spring is limited to a relatively fixed position between the pressure plate 4 and the bottom plate 6, avoiding shock-absorbing foot pads Under heavy pressure or vibration, the spring will move horizontally, which also greatly ensures that the spring exerts force in the vertical direction and prolongs the service life. In addition, the way that the spring 5 is nested with the boss 3 and the recess 13 also makes it very easy to disassemble and install when the spring is damaged, and reduces the difficulty of maintenance of the shock-absorbing foot pad.

As shown in Figures 1-4, in this embodiment, there are 6 springs 5, bosses 3, and recesses 13 respectively, and the 6 springs are evenly distributed between the pressure plate and the bottom plate and one end of the spring is connected to the bottom plate.

The center of the main bolt 1 is provided with a spherical groove, and the said spherical groove is provided with a threaded groove for fixing the anchor bolts. The spherical groove can further reduce the lateral movement of the machine tool relative to the shock-absorbing foot pad. The machine tool and other equipment arranged on the shock-absorbing foot pad are connected and fixed with the thread groove on the main bolt 1 through the anchor screw, which prevents the machine tool and other equipment from directly nailing the anchor screw on the floor, thereby protecting the floor and maintaining the machine tool Wait for the stability of the equipment.

In order to prevent the spring in the shock-absorbing foot pad from bursting out under pressure and injuring field personnel during production, a baffle plate is welded on the bottom plate, and the baffle plate is arranged on the outside of the spring. The number and width of the baffles can be set according to the ratio of the size of the shock-absorbing foot pads. As shown in the figure, there are 2 baffles, one at the front and one at the front.

When in use, the machine tool can be lifted with a forklift, the required shock-absorbing feet are placed under the anchor holes of the machine tool, the anchor bolts are penetrated, and screwed to contact with the spherical groove of the main bolt 1 on the feet, and then the machine tool level is adjusted (bolt Rotate clockwise to raise the machine tool); after adjusting the level of the machine tool, tighten the nuts on the anchor bolts to fix the level state.

Therefore, the shock-absorbing foot pad provided by the utility model can effectively attenuate the vibration of the machine itself, reduce the external transmission of vibration force, prevent the introduction of vibration force, ensure the processing dimensional accuracy and quality of the machine tool arranged on the foot pad, and control the structure of the building.
