Description

Technical Field

[0001] The utility model relates to the technical field of a CNC machine tool base, in particular to a base device for a CNC machine tool. Background Art

[0002] As a chip forming device for mechanical parts, CNC machine tools need to ensure stable performance in order to ensure the requirements of machining accuracy. Therefore, the base device used for CNC machine tools is an important process component.

[0003] After searching, the application with patent number CN205520476U discloses a base device for a CNC machine tool, which includes a bracket connected to the CNC machine tool, an axis tube arranged on the foundation surface, a core shaft arranged in the axis tube, a rubber rod arranged between the core shaft and the axis tube and used to absorb the vibration energy of the CNC machine tool, and a swing arm arranged between the core shaft and the bracket. It also includes a support block, a spring and a base. The axis tube is arranged in the base, and the vibration energy is absorbed by the rubber rod to improve the stability of the CNC machine tool.

[0004] However, due to the setting of the bracket and the support block, the CNC machine tool is placed on the bracket, and the size of the bracket remains unchanged, resulting in that only one specification of CNC machine tools can be placed on the bracket. When using different CNC machine tools, it is necessary to replace the corresponding bracket, which has a high cost and certain limitations. At the same time, due to the setting of the rubber rod and the swing arm, the vibration generated when the CNC machine tool is in use is transmitted to the rubber rod through the swing arm. The rubber rod has a poor shock absorption effect and the swing arm is prone to shaking, which leads to the stability of the CNC machine tool and the poor seismic resistance of the base.

[0005] Therefore, we propose a base device for CNC machine tools. Utility Model Content

The top surface of the hydraulic telescopic column is provided with a groove, and a shock-absorbing column is fixedly installed in the groove. The shock-absorbing column extends into the base, and a shock-absorbing spring and a damper are installed in the shock-absorbing column. A shock absorber placed horizontally and connected to the electric telescopic rod is installed in the fixed plate.

[0010] Preferably, four sets of moving wheels in opposite positions are fixedly mounted on the bottom of the support plate, so that the base can be easily moved, thereby moving the CNC machine tool.

[0012] Preferably, the abutment plate is made of steel material, which can improve the strength of the abutment plate.

[0013] Preferably, the clamping plate is connected to the electric telescopic rod via a slot, so that the clamping plate can be easily replaced to facilitate clamping and fixing of different CNC machine tools.
