A Quick Leveling Device for CNC Machine Tool

Abstract

The invention discloses a fast leveling device for a numerically controlled machine tool, which comprises a base and a leveling seat arranged at the upper end thereof. The lower end of the base is provided with a support pad, and the middle part of the upper surface of the base is provided with a horizontal adjustment unit three perpendicular to each other. Level adjustment unit 2, level adjustment unit 1 and level adjustment unit 2 are perpendicular to each other. This leveling device reduces the trouble of frequently changing the direction of the level ruler. Level the leveling seat before each leveling to ensure the leveling accuracy of the machine tool , Protect the placement surface of the leveling seat through the rubber ring to avoid damage caused by bumps.

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to a fast leveling device for numerical control machine tools. Background technique [0002] CNC machine tools are one of the main equipment of modern mechanical processing. After the machine tool factory completes the machine tool assembly and debugging, it will send the machine tool to each machinery factory. After the machine tool is placed, it will be assembled first, and the parts removed during transportation will be restored to the CNC machine tool. In itself, the machine tool must be leveled before it is officially put into production. If the machine tool is not leveled, the guide rail of the machine tool bed will be distorted, the trajectory of the moving parts will change, and the relative position of the tool and the workpiece will change during the process, reducing the machining accuracy. ,Such as figure 2 As shown, there are usually...

[0002] CNC machine tools are one of the main equipment of modern mechanical processing. After the machine tool factory completes the machine tool assembly and debugging, it will send the machine tool to each machinery factory. After the machine tool is placed, it will be assembled first, and the parts removed during transportation will be restored to the CNC machine tool. In itself, the machine tool must be leveled before it is officially put into production. If the machine tool is not leveled, the guide rail of the machine tool bed will be distorted, the trajectory of the moving parts will change, and the relative position of the tool and the workpiece will change during the process, reducing the machining accuracy. ,like figure 2 As shown, there are usually 6-8 feet on the bottom of the machine tool. Move the table to the center of the X and Y axes, first place the level in the middle of the table in a direction parallel to the X axis, and observe the bubble position of the level. Determine the front and rear heights of the machine tool, then adjust the height of the feet at the front and rear positions, and then place the level in the middle of the workbench in a direction parallel to the Y axis, judge the height of the machine tool left and right, and then adjust the height of the feet at the left and right positions. After the adjustment, it will affect the front and rear positions. It is necessary to change the placement direction of the level repeatedly, and the adjustment process is cumbersome.

[0003] After using one end of the level for a long time, due to other behaviors such as handling or bumping, the accuracy of the level tube on the level will decrease. Before leveling the machine tool, the level needs to be leveled. However, there is no complete level for the level in actual production. It is inconvenient to adjust the level, and the accuracy of the level itself is also an important factor affecting the leveling of the machine tool
