Rapid leveling device of numerical control machine tool

Abstract

The invention discloses a rapid leveling device of a numerical control machine tool. The rapid leveling device comprises a base and a leveling base arranged at the upper end of the base; the base is acuboid with a square lower end surface, and a screw rod is in threaded connection with each of the four corners of the lower end of the base separately, and a supporting pad is arranged at the lowerend of each screw rod; horizontal adjusting units III which are perpendicular to each other are arranged in the middle of the upper end face of the base; the leveling base is of a square frame structure, and a horizontal adjusting unit I and a horizontal adjusting unit II which are parallel to the edge of the leveling base are arranged at the upper end of the leveling base; and the horizontal adjusting unit I and the horizontal adjusting unit II are perpendicular to each other. B virtue of the rapid leveling device, the trouble of frequently replacing the horizontal ruler direction is reduced,the leveling base is leveled before each time of leveling, so that the leveling precision of the machine tool is guaranteed, and damage caused by collision is avoided by protecting the placing surface of the leveling base through a rubber ring.

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.

[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
