[0002] With the continuous advancement of manufacturing technology and the acceleration of the global industrialization process, CNC machine tools, as the core equipment in the field of modern mechanical processing, have a technology development level that is directly related to processing accuracy, production efficiency and manufacturing costs. In recent years, five-axis CNC machine tools have gradually become the preferred tool for high-precision, complex-shaped workpiece processing due to their excellent processing capabilities and flexibility. Five-axis linkage processing technology achieves all-round and precise control of the spatial position of the workpiece by simultaneously controlling the movement of five axes, thereby completing complex processing tasks that are difficult to complete with traditional three-axis or four-axis machine tools.

[0003] However, despite the significant technological progress of five-axis CNC machine tools, most of the five-axis CNC machine tools on the market are large in size, expensive, and complicated to operate. This is undoubtedly a major challenge for educational institutions. When cultivating students' practical skills, educational institutions need to provide students with sufficient practice opportunities and platforms, but the high equipment purchase cost and complex operation and maintenance procedures limit the widespread application of five-axis CNC machine tools in education and teaching. In addition, the design of existing five-axis CNC machine tools is often too complicated, which is not conducive to students quickly mastering and understanding their working principles and operating procedures, thereby affecting the teaching effect and students' learning experience, so staff need to improve them. Summary of the invention

[0024] With the continuous advancement of manufacturing technology and the improvement of education's requirements for practical skills, the micro five-axis CNC machine tool has gradually become an important tool for school mechanical processing and CNC technology teaching due to its low price and comprehensive functions. The advantages of the machine tool of the present invention in school use will be described in detail below.

[0025] The price is low, reducing the cost of education.

[0026] Compared with large, high-end CNC machine tools, micro five-axis CNC machine tools are more affordable while ensuring basic functions and processing accuracy. This allows schools to purchase multiple devices without investing a lot of money to meet the practical needs of more students. At the same time, its maintenance cost is relatively low, further reducing the financial burden on schools.

[0027] Comprehensive functions to meet teaching needs.

[0028] The micro five-axis CNC machine tool has the ability of five-axis linkage processing, which can realize the precise processing of complex-shaped workpieces. This feature enables the school to provide students with more abundant practical cases and processing tasks when teaching courses such as CNC technology, mechanical design, and secondary development of CNC systems. Students can operate machine tools and deeply understand key skills such as CNC programming, tool path planning, and processing parameter setting, thereby comprehensively improving their practical ability and professional quality.

[0029] Easy to operate and maintain, suitable for school environment.

[0030] The design of micro five-axis CNC machine tools is usually more compact and concise, which is convenient for students to operate and learn in a limited space. At the same time, its control system and operation interface are relatively intuitive and easy to understand, which reduces the learning difficulty of students. In addition, the maintenance of the machine tool is also relatively simple. The school can arrange special teachers or technicians to conduct regular inspections and maintenance to ensure the normal operation and long-term use of the machine tool.

[0031] Promote the integration of industry, academia and research, and enhance the school's influence.

[0032] By introducing micro five-axis CNC machine tools, the school can carry out closer industry-university-research cooperation with enterprises and scientific research institutions. The school can use machine tools to research and develop scientific research projects, provide technical support and talent training for enterprises; at the same time, enterprises can also provide schools with practice bases and employment opportunities to jointly promote the development and innovation of manufacturing technology. This cooperation model not only helps to improve the school's scientific research strength and teaching level, but also enhances the school's social influence and competitiveness.

[0033] The working principle of the micro five-axis CNC machine tool of this embodiment: Movement in the Y-axis direction: The first driving mechanism 2 provides power to drive the first conductive plate 3 to slide on the top of the mounting bracket 1, thereby realizing movement in the Y-axis direction. This movement provides basic position adjustment for subsequent processing.

[0034] Movement in the X-axis direction: The second driving mechanism 4 is fixedly mounted on one side of the slide 5, and its output end is connected to the second conductive plate 6. The second driving mechanism 4 provides power to drive the second conductive plate 6 to slide on the slide 5 to achieve movement in the X-axis direction. In this way, combined with the movement in the Y-axis direction, the precise position of the workpiece on the plane can be further determined.

[0035] Movement in the Z-axis direction: The connecting sleeve 8 is slidably connected to the surface of the second conductive plate 6, and is driven by the third driving mechanism 7 to realize the movement in the Z-axis direction, that is, the vertical direction. This movement enables the workpiece to be accurately positioned in three-dimensional space.

[0036] At the same time, the output end of the fourth driving mechanism 10 fixed to one side of the mounting bracket 1 is connected to the flip U-shaped frame 11. The fourth driving mechanism 10 provides power to drive the flip U-shaped frame 11 to flip in the mounting bracket 1 to achieve rotation in the A-axis direction. This rotational movement allows the workpiece 9 to be processed at different angles, meeting the processing requirements of complex-shaped workpieces.

[0037] Rotation along the B axis: The fifth driving mechanism 13 is fixedly mounted on the outer convex side of the flip U-shaped frame 11, and its output end is connected to the rotating disk 14. The fifth driving mechanism 13 provides power to drive the rotating disk 14 to rotate in the flip U-shaped frame 11 to achieve rotation in the B-axis direction. This rotational movement combined with the rotation in the A-axis direction can further increase the processing flexibility and accuracy of the workpiece.

[0038] Processing: The workpiece 9 is fixed by the connecting sleeve 8, and the connecting sleeve 8 is slidably arranged on the surface of the second conductive plate 6 to ensure the stability and accuracy of the workpiece during the processing.

[0039] The machine tool achieves precise processing of workpieces through the coordinated work of various drive mechanisms and sensor components. During the processing, the operator can monitor the operating status and processing parameters of the machine tool through the display and make adjustments as needed.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
