[0002] During the machining process, the position of the machining head is adjusted. However, during the machining process, chips and cutting fluid are generated. In order to prevent contaminants such as chips, cutting fluid, and dust from entering the guide rail, lead screw, or drive system, and to avoid collision damage, thereby ensuring equipment accuracy, extending service life, and improving safety, it is necessary to protect the Z-axis. Therefore, a Z-axis mechanism protection structure is required.

[0003] Most existing machining equipment's Z-axis mechanisms are exposed to the air. During the machining process, chips, cutting fluid, and other contaminants can enter the guide rails or lead screws, causing damage to the drive system and affecting the equipment's machining accuracy and lifespan. To prevent chips and cutting fluid from entering the guide rails or lead screws, some machining equipment uses integrated protective covers to protect these structures. However, these integrated protective covers need to be manufactured according to the dimensions of the machining equipment, resulting in high production costs. Furthermore, these integrated protective covers are not easy to disassemble and reassemble, hindering the maintenance and repair of the machining equipment by the operators. Utility Model Content

A protective assembly is also provided on the side wall of the fixed frame 1 to protect the drive assembly. The drive assembly includes two sets of guide rails 2, symmetrically mounted on the side wall of the fixed frame 1, which limit the sliding of the slider 5, ensuring the vertical movement of the mounting frame 6, and thus ensuring the vertical movement of the machining head 8. A motor 3 is bolted to the fixed frame 1 to drive the rotation of a lead screw 4. The output end of the motor 3 is connected to the lead screw 4 via a coupling. A slider 5 is slidably mounted on the outside of the guide rails 2. A mounting frame 6 is bolted to the side wall of the slider 5 to protect the lead screw 4 and also to protect the mounting base 7 from the machining head 8. The machine head 8 and other structures are installed and placed. The mounting bracket 6 has a mounting seat 7 bolted to its side wall for fixing the machining head 8. The machining head 8 is detachably installed in the mounting seat 7 for processing workpieces. A drag chain 9 is provided on one side of the motor 3 for protecting the connecting wires. The mounting bracket 6 and the lead screw 4 are connected together by a transmission component. The surface of the mounting bracket 6 has multiple sets of heat dissipation vents. When processing workpieces is required, the motor 3 drives the lead screw 4 to rotate. The rotation of the lead screw 4 drives the transmission component to move. Under the limit of the guide rail 2 and the slider 5, the transmission component moves vertically. The movement of the transmission component drives the mounting bracket 6 to move. The movement of the mounting bracket 6 drives the fixed seat to move. The movement of the fixed seat drives the machining head 8 to move. The height of the machining head 8 can be adjusted to assist in completing the processing of workpieces.

[0024] The protective assembly includes a first protective cover 10 for protecting the motor 3. The first protective cover 10 is bolted to the top of the mounting frame 6. A second protective cover 11 is bolted to the side wall of the first protective cover 10 for protecting the cable chain 9 and connecting wires. Two sets of first connecting plates 12 are symmetrically bolted to the side wall of the mounting frame 6 for installing and fixing the second connecting plates 14. Multiple through holes 13 are formed on the surface of the first connecting plates 12 to facilitate connection and fixing between the first connecting plates 12 and the mounting frame 6. The second connecting plates 14 are bolted to the side wall of the first connecting plates 12 for installing and fixing the side guard plates 15. A side guard plate 15 is bolted to the side wall of the second connecting plate 14 to protect the lead screw 4 and other structures. A bottom guard plate 16 is bolted to the bottom of the side guard plate 15 to protect the machining head 8 and other structures. An air nozzle 17 is bolted to the side wall of the side guard plate 15 to blow away debris and cutting fluid generated during machining. The first protective cover 10 is bolted to the cable chain 9. Magnetic strips 18 are provided on the surfaces of the first protective cover 10, the second protective cover 11, the first connecting plate 12, the second connecting plate 14, the side guard plate 15, and the bottom guard plate 16 to facilitate subsequent disassembly and assembly of the protective structure. The side guard plate 15 is connected to the mounting bracket 6 via... The bottom protective plate 16 is fitted onto the outside of the processing machine head 8 and the air nozzle 17 is connected to the air pump via a hose. When installing the protective components, the user first magnetically attaches the first connecting plate 12 to the mounting bracket 6 using the magnetic strip 18, then uses bolts to install and fix the first connecting plate 12 to the mounting bracket 6. Next, the first protective cover 10 is connected and fixed to the mounting bracket 6 and the drag chain 9. Then, the second protective cover 11 is magnetically attached to the first protective cover 10 using the magnetic strip 18 and fixed with bolts. Then, the side protective plate 15 is magnetically attached to the second protective cover 11 using the magnetic strip 18. Finally, the side protective plate 15 is connected to the mounting bracket 6 and the second connecting plate 11. Plate 14 is installed and fixed together, and then the bottom guard plate 16 is attached to the bottom of the second connecting plate 14 by magnetic strip 18. Finally, the bottom guard plate 16 is connected and fixed to the side guard plate 15, thus completing the installation and fixing of the protective structure and protecting the lead screw 4, motor 3, and other structures. The separate design of the first guard 10, second guard 11, first connecting plate 12, second connecting plate 14, side guard plate 15, and bottom guard plate 16 facilitates the separate assembly and disassembly of each component, making it convenient for workers to inspect and maintain the machining equipment. With the magnetic strip 18, workers do not need to support or limit the components of the protective structure, facilitating the installation of the protective structure. With the air nozzle 17, debris or cutting fluid generated during processing can be blown away to form a protective air curtain, preventing debris or cutting fluid from splashing into the lead screw 4 and other structures, achieving a good protective effect.
