In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.
[0019] See also Figures 1 to 4 The double-layer protective structure 4 of the XZ axis 6 of the machine tool of the embodiment of the utility model comprises a base 1, a Y-axis guide rail 2 arranged on the base 1, and a workbench 3 slidably arranged on the Y-axis guide rail 2. The double-layer protective structure 4 comprises a first protective structure 41 and a second protective structure 42. The first protective structure 41 is arranged on the movable parts of the workbench 3 and the Y-axis guide rail 2, and the second protective structure 42 is arranged on the fixed part of the workbench 3 and the Y-axis guide rail 2 and close to the movable parts.
[0020] In the above embodiment, the first protective structure 41 tightly wraps the moving parts to prevent them from slipping or shifting during movement, thereby ensuring the stability of the machine tool operation. At the same time, the second protective structure 42 provides additional protection for the gaps that may appear in the first protective structure 41 to prevent processing waste residues, chips and other debris from entering, thereby ensuring the processing accuracy of the machine tool.
[0021] More specifically, the first protective structure 41 is mainly designed around the movable parts of the machine tool, such as the guide groove of the X-axis 5, the telescopic shaft and the side of the workbench 3. Since these parts need to be moved frequently, the first protective structure 41 needs to be protected to ensure that they always maintain the protective effect on the movable parts during the operation of the machine tool. The second protective structure 42 is arranged on relatively fixed parts close to the first protective structure 41, such as the X-axis 5 drag box 421, the drag line baffle 422 and the crossbeam baffle 423. The role of these parts is to supplement the gaps or loopholes that may appear in the first protective structure 41, and prevent processing waste slag, chips and other debris from entering the interior of the machine tool through the gaps, affecting the normal operation of the machine tool. During the operation of the machine tool, the double-layer protective structure 4 works together to form a complete protection system to ensure the safe, stable and efficient operation of the machine tool. At the same time, through reasonable design and material selection, the double-layer protective structure 4 can also effectively resist the vibration and impact generated during the operation of the machine tool, and maintain its long-term protective effect. In summary, the double-layer protection structure 4 of the XZ axis 6 of the machine tool realizes comprehensive protection of the moving parts and fixed parts of the machine tool through the double protection design, improves the reliability, safety and work efficiency of the machine tool, and provides strong support for the development of the modern mechanical processing industry.
[0022] See also Figures 1 to 4 In another embodiment, the first protective structure 41 includes a guide groove shield 411 arranged on the X-axis 5 of the workbench 3, a dust shield 412 arranged on the side of the workbench 3, and a telescopic shield 413 arranged on the X-axis 5, and the second protective structure 42 includes an X-axis 5 drag box 421 arranged on the X-axis 5 and on one side of the guide groove shield 411, a drag line baffle 422 arranged on one side of the X-axis 5 drag box 421, and two beam baffles 423 arranged on the crossbeam of the workbench 3.
[0023] In the above embodiment, the guide groove shield 411 is tightly fitted to the guide groove of the X-axis 5 to prevent waste slag, chips, etc. generated during the processing from entering the guide groove, ensuring the smooth movement of the X-axis 5. The dust shield 412: covers the side of the workbench 3, effectively preventing dust, debris, etc. generated during the cutting process from damaging the electronic components and transmission mechanism inside the workbench 3. The telescopic shield 413 of the X-axis 5 is telescopic with the telescopic extension of the X-axis 5, always maintaining the protection of the telescopic part of the X-axis 5 to avoid external factors from affecting it. The X-axis 5 drag box 421 is located on one side of the X-axis 5, and together with the guide groove shield 411, it forms a double protection for the X-axis 5, preventing waste slag, chips, etc. from entering from the gap between the guide groove shield 411 and the X-axis 5. The drag wire baffle 422: is set on one side of the X-axis 5 drag box 421, and its main function is to prevent the cables from being worn or interfered during the operation of the machine tool, ensuring the normal operation of the electrical system of the machine tool. The crossbeam baffle 423 is arranged on the crossbeam of the workbench 3 to play the role of fixing and protecting, and prevent external objects from causing impact or damage to the crossbeam.
[0024] See also Figures 1 to 4 In another embodiment, the workbench 3 further includes a Z-axis 6, and a carving knife component is disposed on the Z-axis 6. The carving knife component includes a carving head and a Z-axis 6 telescopic device, and the carving knife is disposed on the Z-axis 6 telescopic device, and the Z-axis 6 telescopic device is provided with a telescopic shield 413. The outermost layer of the Z-axis 6 telescopic device is also provided with a rigid shield, and the rigid shield wraps the telescopic shield 413.
[0025] In the above embodiment, by precisely protecting the telescopic device of the Z axis 6 and the chisel component, the interference of external factors on the movement of the chisel is reduced, thereby improving the processing accuracy and product quality. At the same time, the presence of the rigid shield also enhances the overall stability of the machine tool. The telescopic shield 413 and the rigid shield jointly protect the chisel component from dust, chips and other debris, reducing the wear of the chisel and extending its service life.
[0026] See also Figures 1 to 4 In another embodiment, the rigid shield is provided with a sealing ring.
[0027] In the above embodiment, when the Z-axis 6 telescopic device performs lifting and lowering motion, the sealing ring and the contact surface of the Z-axis 6 telescopic device always maintain a close fit, forming an effective sealing barrier. This barrier not only prevents external debris from entering the Z-axis 6 telescopic device, but also prevents the leakage of liquids such as lubricating oil inside the machine tool. In addition, the design of the sealing ring also takes into account the vibration and impact that may be generated during the operation of the machine tool. The sealing ring is made of a material with excellent elasticity and wear resistance, which can maintain stable sealing performance during the operation of the machine tool, and can maintain the sealing effect even in the case of vibration and impact.
[0028] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
