Background

The installation of a high-precision machine tool has very high requirements on the flatness of the ground, the machine tool can vibrate due to uneven installation due to the height error of zero millimeters, and the machining precision of the machine tool can be directly influenced by the vibration generated by the machine tool.

The traditional machine tool basically adopts the bolts to connect the machine tool feet and the hard link of the base in the installation of the base, because the flatness of a plurality of bases can not be absolutely guaranteed on the same plane, the mode of adding a gasket foot pad is basically adopted for adjustment when the stability of the machine tool feet is adjusted, the thickness of the adjusting gasket of the general machine tool feet is 0.25mm, 0.5mm, 0.75mm and 1mm, and then the machine tool feet of most machine tools are not stably installed, the machine tool and a machine tool frame can resonate to form shaking type vibration when the machine tool operates, the shaking type vibration is only generated, the light degree is different, and the vibration can cause the reduction of the processing precision.

At present, the machine tool foot is installed on the base through the matching of a screw rod and a screw sleeve, the machine tool foot is extended and shortened to be adjusted through rotating the screw rod, but the force application of the rotating screw rod and the tightness of the matching of the screw rod and the screw sleeve cannot be completely the same, so that the stability of the machine tool foot and the base is adjusted to be different, and therefore the machine tool and the machine tool frame have slight resonance in different degrees to form slight shaking type vibration, and the machining precision is reduced.

In order to reduce the resonance of the machine tool during operation, machine tool manufacturers increase the material thickness, strength and weight of the machine bed frame during the production of the machine tool, and attempt to reduce the resonance of the machine tool during operation by the strength of the machine bed frame. This approach, while reducing the resonance of the machine tool in operation, increases the material consumption and production costs of the machine tool, and, at the same time, increases the transportation and handling costs of the machine tool.

The parent and the parent do technical research and machining, the parent and the parent have lathes, milling machines, planing machines, boring machines, grinding machines and drilling machines in a processing factory, and the parent can independently operate the lathes at the age of 12 years, so that the parent and the parent can know the performance of the lathes. The problems occurring at the time of mounting of the foot of the present machine tool are felt to be common through physical knowledge learned in schools, and the presently disclosed technology cannot solve the technical problems. Therefore, in order to ensure that the machine tool foot is contacted with the ground and stably implemented, reduce the production weight of the machine tool and reduce the production cost of the machine tool, long-term research shows that the machine tool foot can be freely stretched to be contacted with the ground and stably implemented, can quickly lock the length of the stretched machine tool foot, and can adapt to stable installation on the ground without adjustment.

2. the technical problem that the machining precision of the machine tool is reduced because the lower end of the machine tool foot cannot be in complete contact with the uneven ground and the traditional machine tool is easy to resonate during operation because the full-floating support cannot be adopted between the traditional machine tool and the machine tool foot is solved;
