[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-4 An external protective structure for a gantry machining center is provided. This external protective structure for the gantry machining center adopts a modular design, including a top cover module 1, a left side cover module 2, a right side cover module 3, and a rear cover module 4, and the modules together enclose the machining chamber. The top cover module 1 spans and is fixed to the gantry beam of the gantry machining center, and is connected to the machine tool bed by bolts. A ventilation box 101 is installed on the top of the top cover module 1, and a cooling fan is installed inside the ventilation box 101 (the fan speed is adjusted according to the machining load, with a wind speed of 3m / s under light load and increased to 5m / s under heavy load). The left side cover module 2 and the right side cover module 3 are symmetrically arranged and installed on both sides of the top cover module 1 by a slide rail structure, and can slide along the Y direction. The rear cover module 4 is fixedly installed at the rear end of the machine tool bed. In application, the modular combination of the top cover, side cover and rear cover facilitates installation, disassembly and maintenance, while forming a closed machining chamber, isolating cutting splashes and noise, improving safety. Combined with the cooling fan and ventilation box 101, heat is directionally discharged, reducing the impact of disordered heat diffusion on the precision components of the guide rail and lead screw, and suppressing thermal deformation. At the same time, the side covers (left side cover module 2 and right side cover module 3) are designed to slide along the Y direction, which facilitates the adjustment of machining space or maintenance equipment and adapts to the needs of workpieces of different sizes.

[0020] Reference Figures 1-3 The ventilation box 101 is made of sound-absorbing material (such as polyurethane foam) to reduce noise to below 75dB. In application, the use of sound-absorbing material in the ventilation box 101 significantly reduces the operating noise of the fan and improves the working environment.

[0021] Reference Figures 1-3A chip filter 102 is installed on the air inlet of the ventilation box 101. The air outlet 103 on the ventilation box 101 is set towards the spindle box on the gantry beam. The air outlet 103 is tilted 15°-30° towards the spindle box to ensure that the airflow blows directly to the heating area. In application, the chip filter 102 on the air inlet can prevent chips from entering the ventilation system, avoiding blockage and damage to the fan. At the same time, the air outlet 103 facing the spindle box can target the cooling of the core heating components and improve heat dissipation efficiency.

[0022] Reference Figure 4 The rear cover module 4 is equipped with an observation window 401 (made of impact-resistant acrylic material with a light transmittance of ≥90%). In application, the observation window 401 on the rear cover module 4 is designed to facilitate real-time monitoring of the processing status, taking into account both safety and ease of operation.

[0023] Reference Figure 3 and Figure 4 The slide rail structure includes T-shaped slide grooves 104 symmetrically arranged on both sides of the top cover module 1 and T-shaped slide plates 5 installed on the left side cover module 2 and the right side cover module 3 respectively and corresponding to the T-shaped slide grooves 104. The T-shaped slide plates 5 are adapted to the T-shaped slide grooves 104. The left side cover module 2 and the right side cover module 3 are slidably installed on the top cover module 1 through the T-shaped slide plates 5 and the T-shaped slide grooves 104. In application, the cooperation between the T-shaped slide grooves 104 and the T-shaped slide plates 5 can ensure that the side covers (left side cover module 2 and right side cover module 3) slide smoothly and are accurately positioned, preventing deviation or derailment.

[0024] Reference Figures 1-3 The left cover module 2 and the right cover module 3 are equipped with handles 7 for applying force. In application, the handles 7 on the left cover module 2 and the right cover module 3 provide a force application point, simplifying manual opening and closing operations and improving maintenance efficiency.

[0025] Reference Figures 1-3 The left cover module 2 and the right cover module 3 are made of double-layer hollow polycarbonate panels, and both the left cover module 2 and the right cover module 3 are equipped with reinforcing ribs 6. In application, the double-layer hollow structure has both impact resistance and sound and heat insulation performance. At the same time, the reinforcing ribs 6 enhance the rigidity of the side cover and prevent deformation and vibration from affecting the accuracy.

[0026] The working principle of this utility model is as follows: Before processing: Hold the handle 7 on the side cover (left side cover module 2, right side cover module 3) and pull it outward to the limit of the slide rail stroke. Adjust the opening and closing degree of the side cover according to the workpiece size, and ensure that the side cover is stable and does not shake. Then check that the observation window 401 is clean and unobstructed, the air outlet 103 of the ventilation box 101 is unobstructed, and confirm that the chip screen 102 is undamaged and the cooling fan is powered on and performs a normal self-test. During the machining process: turn on the cooling fan, set the fan speed through the external control panel, and monitor the temperature inside the machining chamber in real time. If it exceeds 40℃, switch to the high speed. At the same time, check the tool status and chip accumulation through the observation window 401 regularly. Clean the chip screen 102 every once in a while (e.g., every 30 minutes). If an emergency stop is required, turn off the spindle first, and then adjust the side cover.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
