Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a leveling structure and leveling method for a CNC machine tool. Background Technology

[0002] When CNC machine tools are producing workpieces, the electrical control execution system controls the movement of the CNC machine tools to automate the production of parts. In order to ensure production accuracy, CNC machine tools often use leveling mechanisms to adjust the placement of the CNC machine tools and ensure that the CNC machine tools are placed horizontally.

[0003] However, most existing leveling mechanisms are directly fixed on CNC machine tools and integrated with them. Moreover, each leveling mechanism can only be used for one type of CNC machine tool, resulting in poor applicability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a leveling structure and method for CNC machine tools, which solves the problems that most existing leveling mechanisms are directly fixedly installed on CNC machine tools and integrated with them, and that each leveling mechanism can only be used for one type of CNC machine tool, resulting in poor applicability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a CNC machine tool leveling structure, comprising an adjustment plate, on which four fastening components capable of moving within a certain range are mounted via a drive assembly. The fastening components are used to fix the support legs of the CNC machine tool. An adjustment groove is provided below the adjustment plate, and a bottom box with a top opening is provided in the adjustment groove. Four adjustment components for adjusting the height of the adjustment plate are provided in the bottom box, and an adjustment motor for driving the adjustment component is provided on one side of each adjustment component.

[0006] A leveling method for a leveling structure of a CNC machine tool, the leveling method comprising the following steps: S1: Adjust the position of the fastening assembly, start the drive motor, the drive motor drives the drive rod to rotate, and the threaded engagement between the drive thread and the guide block drives the first fastener and the second fastener to move through the guide block, so that the fastening assembly is aligned with the support foot of the CNC machine tool. S2 secures the support foot with a fastening assembly, inserts the CNC machine tool foot into the groove of the first fastener through the first notch, aligns the second notch on the second fastener with the first notch on the first fastener, and secures the first fastener and the second fastener together through the threaded engagement between the fixing bolt and the connecting part, thereby completing the installation and fixation of the device. S3 levels the CNC machine tool. Based on the tilt angle of the CNC machine tool, the corresponding adjustment motor is started. The adjustment motor drives the adjustment gear to rotate slowly. Utilizing the meshing between the adjustment gear and its teeth, the threaded cap rotates. Then, using the threaded engagement between the threaded cap and the threaded rod, the position of the threaded rod inside the outer tube is adjusted, thereby adjusting the height of the overall adjustment assembly. In this way, the other three adjustment assemblies are adjusted to complete the leveling of the CNC machine tool.

[0007] This invention provides a leveling structure and method for CNC machine tools, which has the following beneficial effects: This device can adjust the position of the fastening components to adapt to CNC machine tools of different sizes and specifications. At the same time, the tilt angle of the adjustment plate can be adjusted by the adjustment components to make the surface of the CNC machine tool more horizontal. Attached Figure Description
