[0031] Specifically, the driving motor 10 drives the active pulley 9 to rotate; the rotation of the active pulley 9 is linked to the driven pulley 7 through the connecting belt 8 to rotate synchronously; through the rotation of the active pulley 9, the threaded rod 5 is rotated synchronously; this process plays a role in transmitting power, transmitting the rotational force of the active pulley 9 to the threaded rod 5; the rotation of the threaded rod 5 drives the movable plate 11 and the limit ring 12 to move; this step realizes the movement of the coolant discharge pipe, so that the coolant can be sprayed to a wider position, thereby increasing the cooling range; the coolant is sprayed through the discharge pipe; during the processing of the gantry milling machine, the spraying of the coolant can effectively reduce the temperature of the tool and the workpiece, reduce thermal deformation, and improve the processing accuracy.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The filtering mechanism 2 includes a worm 205, the left end of which is fixedly connected to the right side of the driven pulley 7, an external frame 201 is fixedly connected to the bottom of the front side of the machine tool 1, a worm wheel 204 is rotatably connected to the rear side of the external frame 201, the worm wheel 204 is meshedly connected to the worm 205, a gear 206 is fixedly connected to the rear side of the worm wheel 204, a sawtooth bar 208 is provided on the bottom wall of the machine tool 1, the gear 206 is meshedly connected to the sawtooth bar 208, a brush rod 202 is installed on the rear side of the sawtooth bar 208, a storage box 203 is provided on the outer bottom of the machine tool 1, a filter plate 207 is installed on the inner side of the storage box 203; a slide rail 13 is fixedly connected to the left side of the bottom wall of the machine tool 1, and the sawtooth bar 208 is slidably connected to the slide rail 13;

[0033] Specifically, the worm wheel 204 and the gear 206 are connected by rotation, which further expands the transmission range of the driving force and enhances the transmission performance of the device; the sawtooth bar 208 is meshed with the worm wheel 204 for transmission, so that the sawtooth bar 208 can slide smoothly in the slide rail 13; this design cleverly plans the movement trajectory of the sawtooth bar 208, ensuring that it can complete the task accurately and quickly during work; the movement of the sawtooth bar 208 also drives the brush rod 202 to move synchronously; in this way, the surface of the filter plate 207 can be brushed by the brush rod 202, effectively removing impurities on the surface of the filter plate 207; this design greatly reduces the problem of poor filtration caused by impurity blockage during coolant filtration, and improves filtration efficiency.

[0037] And through the rotation of the driven pulley 7, the worm 205 is rotated together, and the rotation of the worm 205 drives the worm wheel 204 to rotate synchronously. Through the rotation of the worm wheel 204, the gear 206 is rotated together, and meshing transmission with the sawtooth bar 208 is performed, thereby driving the sawtooth bar 208 to slide in the slide rail 13, and the movement trajectory of the sawtooth bar 208 is planned. Through the movement of the sawtooth bar 208, the brush rod 202 is moved synchronously to brush and clean the surface of the filter plate 207.
