Description

Technical Field

[0001] The invention belongs to the field of composite material processing, and in particular relates to an automatic tool changing device for composite material processing equipment. Background Art

[0002] Composite materials are used in more and more equipment due to their superior properties compared to metal materials, such as various types of UAV bodies, structural parts, ammunition casings, and various parts supported by composite materials, especially carbon fiber composite materials, which usually require mechanical processing to meet various assembly needs.

[0003] In many application fields, the size of composite materials components is often relatively large. In the process of mechanical processing of such components, large processing equipment is required. Due to the inherent characteristics of composite materials, the wear on the cutting tools is relatively large, and special cutting tools are required to be processed at high speeds. The current general CNC machine tools are not suitable. Therefore, it is necessary to design a device specifically for the processing of composite materials, especially carbon fiber composite materials, using special cutting tools and high-speed spindles for composite materials. In addition, composite components often have many features that need to be processed, requiring a variety of different types of cutting tools. In order to improve processing efficiency and prevent errors caused by manual tool changes, it is also necessary to design a device with automatic tool change function. Summary of the invention
