Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a compact variable frequency integrated CNC machine tool. Background Technology

[0002] CNC machine tools are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other operations.

[0003] According to CN220407987U, a compact CNC machine tool is disclosed. This technology discloses "a compact CNC machine tool, including a bed, a material holder mechanism, a spindle mechanism, and a tool magazine mechanism. The material holder mechanism includes a material holder and a first Y-axis linear drive mechanism; the spindle mechanism includes a gantry support, an X-axis linear drive mechanism, a Z-axis linear drive mechanism, and a spindle. The gantry support includes columns fixedly connected to both sides of the top of the bed and a crossbeam fixedly connected between the tops of the two columns. The X-axis linear drive mechanism can drive the Z-axis linear drive mechanism to move along the X-axis direction, and the spindle can move up and down under the drive of the Z-axis linear drive mechanism." It has the following technical effects: "The tool magazine mechanism includes a transverse support plate fixedly connected between the two columns, a tool magazine assembly, and a second Y-axis linear drive mechanism, which can reduce the spindle's travel distance, reduce machine tool energy consumption, and effectively improve tool changing efficiency. The tool magazine utilizes the space under the gantry support, reducing the machine tool's volume and improving its structural compactness."

[0004] Fixed machining table dimensions limit a machine tool's processing capabilities, restricting it to handling workpieces within a specific size range. This limitation is particularly pronounced when dealing with the localized machining of large workpieces, often requiring specific tooling fixtures or cumbersome adjustments to the workpiece's position to fit the machine tool's processing range. This series of operations not only significantly increases the complexity of the operation but can also negatively impact machining accuracy and efficiency. However, while choosing a machining table with a larger overall size can solve the machining problem for large workpieces to some extent, it correspondingly increases the space required in the factory.

When the area of ​​the main component needs to be expanded, the auxiliary platforms at both ends are flipped to the horizontal, and then the crossbeam is pulled to move below the auxiliary platforms. The crossbeam drives the second support rod to extend in conjunction with the first support rod, thereby supporting the auxiliary platforms and improving their load-bearing capacity and stability. When not in use, the auxiliary platforms at both ends can be flipped and folded to reduce the space occupied.

[0006] To achieve the above object, the utility model discloses a compact structure variable frequency integrated numerical control machine tool through the following technical scheme, a numerical control machine tool is provided with the machining table for fixing and supporting the workpiece to be processed on the numerical control machine tool, and the machining table comprises:
