[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] See Figures 1 to 3 The protective cover assembly 1 includes a protective cover 10, a baffle 20, and a flushing mechanism 30.

[0022] The baffle 20 is installed on the side of the cover 10, and a gap is formed between the baffle 20 and the cover 10. The flushing mechanism 30 is located in the gap and is installed on the baffle 20.

[0023] Specifically, the protective cover 10 is retractable. The spindle is mounted on the protective cover 10, and the protective cover 10 extends and retracts with the spindle movement, flexibly adapting to different processing needs. Simultaneously, the protective cover 10 and the baffle 20 divide the machine tool into a processing area and a functional area. The processing area mainly houses the workpiece, cutting tools, spindle, etc., and is responsible for performing the actual processing tasks. The functional area mainly houses the electrical system, control system, transmission device, and cooling system, providing power and support to the machine tool. During processing, the protective cover 10 automatically extends and retracts with the spindle, always separating the machine tool's functional area and processing area, preventing the cutting fluid in the processing area from... Debris and other contaminants may splash onto the functional areas of the machine tool. However, during the extension and retraction of the cover 10, debris can easily be carried into the gap between the baffle 20 and the cover 10. This can lead to the cover 10 not extending and retracting smoothly, causing jamming, and can also cause debris to enter the functional areas of the machine tool, contaminating the components therein. To solve the above problems, this application provides a cover assembly 1 that includes a flushing mechanism 30. The flushing mechanism 30, located between the baffle 20 and the cover 10, can remove debris from the gap between the baffle 20 and the cover 10, reducing jamming of the cover 10 and preventing contamination of the functional areas.

[0024] The flushing mechanism 30 includes a flushing pipe 310, a chip baffle 320, and a guide plate 330. The flushing pipe 310 is mounted on the baffle 20 and is used to flush water to the bottom between the baffle 20 and the cover 10. The chip baffle 320 is mounted on the baffle 20 and is located above the flushing pipe 310. It is used to guide debris to the front of the outlet 311 of the flushing pipe 310. The guide plate 330 is mounted on the baffle 20 and is located below the flushing pipe 310. It is used to guide the water discharged from the flushing pipe 310 to the location where debris accumulates in front of the flushing pipe 310.

[0025] Specifically, the flushing pipe 310, chip baffle 320, and guide plate 330 are all installed on the baffle 20. When the protective cover 10 moves and extends with the spindle, the position of the baffle 20 is fixed. Therefore, the positions of the flushing pipe 310, chip baffle 320, and guide plate 330 on the baffle 20 are fixed, which makes it easy for the flushing pipe 310 to maintain a stable water outlet direction. The flushing pipe 310 is located between the chip baffle 320 and the guide plate 330. The chip baffle 320 guides the debris to the front of the water outlet 311 of the flushing pipe 310. Under the guidance of the guide plate 330, the water flow discharged from the flushing pipe 310 accurately impacts the debris accumulated in front of the water outlet 311, causing the debris to be discharged to the machining area of ​​the machine tool, and then discharged from the chip removal device in the machining area.

[0026] In this application, there is a gap between the baffle 20 and the protective cover 10. The flushing mechanism 30 is installed on the baffle 20 and located in the gap. The flushing pipe 310, chip baffle 320 and guide plate 330 of the flushing mechanism 30 are all located on the surface of the baffle 20. The debris between the baffle 20 and the protective cover 10 slides down along the chip baffle 320 and is concentrated at the outlet 311 of the flushing pipe 310. The guide plate 330 controls the outlet 311 of the flushing pipe 310 to face the location of the debris accumulation, so that the water flow accurately impacts the accumulated debris. The high-pressure water flow sprayed by the flushing pipe 310 through the outlet 311 not only effectively impacts and disperses the accumulated debris, but also discharges the debris to the processing area of ​​the machine tool. This not only reduces the interference of debris on the movement of the protective cover 10 and the interference of debris on the processing process, but also significantly improves the cleanliness of the processing area, optimizes processing efficiency, reduces equipment failure rate, and also improves the safety and accuracy of the processing process.

[0027] See Figure 2 In one embodiment, the distance between the chip baffle 320 and the guide plate 330 gradually decreases in the direction of water outlet from the flushing pipe 310.

[0028] Specifically, the distance between the chip baffle 320 and the guide plate 330 gradually decreases, which can increase the concentration of the water flow, improve the intensity of the water flow, and enhance the impact force of the water flow, thereby effectively flushing away more debris accumulated in front of the outlet 311 of the flushing pipe 310 and improving the flushing effect.

[0029] In one embodiment, the guide plate 330 is rotatably mounted on the baffle 20. That is, the flushing mechanism 30 adopts an adjustable angle guide plate 330, which can be adjusted according to different processing conditions, debris amount and water flow conditions, thereby adjusting the direction of water flow and enhancing the impact force of water flow, and more efficiently removing debris of different types and shapes.

[0030] In another embodiment, the chip baffle 320 is rotatably mounted on the baffle 20. That is, the chip baffle 320 can be adjusted in angle according to the processing conditions and the amount of chips. For example, when there are many chips, the chip baffle 320 is raised to make the angle between the chip baffle 320 and the horizontal direction smaller, so as to prevent chips from falling too fast and accumulating at the outlet 311 of the flushing pipe 310. When there are few chips, the chip baffle 320 is lowered to make the angle between the chip baffle 320 and the horizontal direction larger, thereby increasing the falling speed of the chips and facilitating efficient cleaning of the chips.

[0031] See Figure 3 In one embodiment, the baffle 20 includes a baffle body 210, a first side plate 220, and a second side plate 230. The first side plate 220 is connected to the baffle body 210, and the second side plate 230 is connected to both the baffle body 210 and the first side plate 220. The chip baffle 320 is connected to the first side plate 220 via a first bracket 340, the flushing pipe 310 is mounted on the first side plate 220 via a mounting plate 350, and the guide plate 330 connects the first side plate 220 and the second side plate 230.

[0032] Specifically, the baffle body 210 has a robust structure and is connected to the first side plate 220 and the second side plate 230, providing stable support for them. The chip baffle 320 is connected to the first side plate 220 via the first bracket 340, ensuring a fixed connection and allowing it to be tilted to facilitate chip removal. The flushing pipe 310 is fixed to the first side plate 220 via the mounting plate 350, ensuring a stable water supply and allowing the water jet to carry away chips, thus enhancing the cleaning effect on the gap between the baffle 20 and the cover 10. The guide plate 330 is connected between the first side plate 220 and the second side plate 230, reinforcing the guide plate 330. Since the guide plate 330 guides the water flow, its tilt, connected between the first side plate 220 and the second side plate 230, optimizes the water flow direction, allowing for more precise flushing of the target area and improved cleaning efficiency. In this embodiment, the flushing mechanism 30 is installed on the baffle body 210, the first side plate 220, and the second side plate 230, ensuring its stability and reliability. This allows for long-term use in complex working environments and effectively prevents debris accumulation and water waste, guaranteeing efficient equipment operation and good maintenance.

[0033] In one embodiment, the baffle body 210, the first side plate 220, and the second side plate 230 are integrally formed, ensuring the stability of the baffle 20. Through the integral forming process, the baffle body 210, the first side plate 220, and the second side plate 230 are tightly joined during manufacturing, avoiding the loosening or error problems that may occur with traditional assembly methods, thus enhancing the durability and pressure resistance of the baffle 20. The combination of the baffle body 210, the first side plate 220, and the second side plate 230 forms a robust integral structure, enabling it to withstand greater working pressure and external impacts during use. Furthermore, the integral forming design makes the baffle 20 more streamlined in appearance, reducing unnecessary seams and gaps, and contributing to improved overall sealing and safety.

[0034] In one embodiment, the chip baffle 320 is detachably connected to the first bracket 340. That is, the chip baffle 320 and the first bracket 340 are fixed by a detachable connection, facilitating maintenance and replacement. This design allows operators to easily disassemble the chip baffle 320 when cleaning or replacing it, without disassembling the entire baffle 20, saving time and labor. The detachable connection between the chip baffle 320 and the first bracket 340 can be achieved using bolts, clips, or quick couplings, ensuring a secure and reliable connection while also guaranteeing ease of disassembly. The detachable connection between the chip baffle 320 and the first bracket 340 significantly improves the maintenance efficiency of the baffle 20, reduces downtime, and ensures continuous and efficient operation of the device. Furthermore, the detachable connection facilitates adjustment and adaptation of the chip baffle 320 under different operating conditions.

[0035] In one embodiment, the first bracket 340 is detachably connected to the first side plate 220. That is, the first bracket 340 and the first side plate 220 are fixed by a detachable connection, making maintenance and adjustment of the first bracket 340 more convenient.

The connection between the first mounting plate 350 and the first side plate 220 can be achieved using bolts, clips, or quick connectors, ensuring a secure connection and easy disassembly. This design makes maintenance, replacement, or adjustment of the first mounting plate 350 more convenient, reducing downtime and improving work efficiency.

[0038] Specifically, the sleeve 3520 passes through the mounting plate body 3510 and is firmly fixed to the mounting plate body 3510. The flushing pipe 310 passes stably through the sleeve 3520 and is tightly connected to the inner wall of the sleeve 3520, so that the flushing pipe 310 is fixed inside the sleeve 3520, which improves the stability of the connection between the flushing pipe 310 and the mounting plate 350.

[0039] In one embodiment, the flushing pipe 310 is made of a flexible hose. The hose has good flexibility and pressure resistance, and can adapt to different installation angles and space requirements to ensure smooth water flow. At the same time, the use of the hose also helps to reduce vibration and noise.

[0040] In one embodiment, the mounting plate body 3510 is provided with an adjustment mechanism, which allows the flushing pipe 310 to adjust the water outlet direction as needed, thereby better meeting the usage requirements under different working conditions, improving the flexibility and adaptability of the equipment, and making it more convenient to install and adjust the direction of the flushing pipe 310, reducing the complexity of maintenance and debugging.

[0041] In another embodiment, the flushing pipe 310 is made of rigid pipe, which has strong rigidity and pressure resistance, making it suitable for environments requiring high stability and durability. The rigid pipe is directly fixedly connected to the first side plate 220 of the mounting plate 350, wherein the fixing method can be welding, threaded connection, or other secure fixing methods to ensure that the rigid pipe does not shift or loosen during operation. In addition, the use of rigid pipe also provides better corrosion resistance and high temperature resistance, making it suitable for high-intensity or long-term operation.

[0042] In another embodiment, the rigid pipe is detachably connected to the mounting plate 350, facilitating operation and maintenance. This detachable connection allows operators to easily remove or replace the flush pipe 310 without requiring complex adjustments to the entire device. This detachable connection between the rigid pipe and the mounting plate 350 enhances overall stability and durability.

[0043] In one embodiment, the sleeve 3520 is provided with an internal thread, and the flushing pipe 310 is provided with an external thread that matches the internal thread. The sleeve 3520 and the flushing pipe 310 are spirally connected by the internal thread and the external thread.

[0044] Specifically, the internal thread on the sleeve 3520 and the external thread on the flush pipe 310 are spirally connected, ensuring a secure connection between the sleeve 3520 and the flush pipe 310. The fit between the internal and external threads makes the installation process simpler and more reliable, while also improving the sealing performance of the connection.
