Description

Technical Field

[0001] The utility model relates to the technical field of tool head support for numerical control machine tools, in particular to a high-stability tool head support structure for numerical control machine tools. Background Art

[0002] The high-stability tool head support structure of CNC machine tools refers to a support structure that provides sufficient stability and rigidity during the cutting process to ensure processing quality and production efficiency. Among them, components such as the spindle, forward and backward mechanisms and supporting bearings represent the core technology of the tool head support structure of CNC machine tools. The spindle is driven by a motor to achieve rotational motion. The supporting bearings are used to support the spindle and withstand cutting forces. The forward and backward mechanisms adjust the position of the spindle through components such as sliders and guide rails. At the same time, the design of the tool magazine and tool changing mechanism can also greatly improve the degree of automation of CNC machine tools, reduce manual intervention, and further improve processing efficiency and precision.

[0003] If the cutter head of a CNC machine tool cannot be supported efficiently and stably, it may affect the processing quality. During the cutting process, if the force on the cutter head is unstable, it will cause problems such as vibration and displacement, thereby affecting the processing accuracy and surface quality and reducing production efficiency. An unstable cutter head can easily lead to tool jamming and tool breakage during the cutting process, thereby increasing the frequency of manual intervention, reducing production efficiency, and damaging the life of the tool. An unstable cutter head can also easily cause scratches and wear on the tool, shortening the tool life, increasing the cost of replacing the tool, and increasing the cost of equipment maintenance. During the operation of a CNC machine tool, an unstable cutter head will also bring additional load to the equipment and increase the cost of equipment maintenance and repair. Utility Model Content

Therefore, it is necessary to select the appropriate type and specification according to the actual application requirements. The tool holder 3 is provided with a tool bar 2 inside. In the tool head of the CNC machine tool, the tool bar 2 (or spindle) is the main component for installing the tool. Its function is to connect the cutting tool with the driving force source (such as a motor, a hydraulic cylinder, etc.) to realize rotation and feed motion, thereby completing the processing task.
