[0023] As Figures 1 - 5 shown, the vertical numerical control machine tool with a debris splash guard provided in this embodiment includes the main body 1 of the spindle box. A vertical plate 2 is fixedly connected to one side of the main body 1 of the spindle box. A second motor 201 and a support member 202 are fixedly connected to the side of the vertical plate 2 away from the main body 1 of the spindle box. The support member 202 is located at the middle position of the vertical plate 2, and the second motor 201 is located at the side position of the support member 202. A movable rack 203 is slidably connected to the inner wall of the support member 202. Gears 204 are rotatably connected to the inner walls on both sides of the support member 202. The gears 204 are engaged with the movable rack 203, and the gears 204 are fixedly connected to the output end of the second motor 201. A fixing plate 301 is fixedly connected to one side of the movable rack 203. A splash guard 3 is fixedly connected to one side of the fixing plate 301. A U-shaped member 302 is fixedly connected to the side of the splash guard 3 away from the fixing plate 301. A limit plate 303 is fixedly connected to one end of the U-shaped member 302. A debris collection box 304 is movably arranged in the U-shaped member 302. A handle 305 is fixedly connected to one side of the debris collection box 304. Teeth are provided on the side of the movable rack 203 close to the inner bottom wall of the support member 202. The movable rack 203 is engaged with the gear 204 through the teeth. The splash guard 3 is made of a transparent and high-strength material, and materials such as polycarbonate and polymethyl methacrylate can be used. The output end of the second motor 201 drives the gear 204 to rotate. The gear 204 drives the movable rack 203 to move on the support member 202. The movable rack 203 drives the fixing plate 301 to move. The fixing plate 301 drives the splash guard 3 to move. The splash guard 3 drives the U-shaped member 302 and the debris collection box 304 to move. Thus, by controlling the forward and reverse rotation of the second motor 201, the up and down movement of the splash guard 3 can be controlled. When the main body 1 of the spindle box processes the workpiece, it is convenient to use the splash guard 3 to block the debris generated during the workpiece processing.

[0024] Secondly, as shown in Figure 1 , Figure 3 and Figure 5 , on the inner wall of one side of the U-shaped part 302 close to the splash guard 3, a triangular protrusion 306 is fixedly connected. The triangular protrusion 306 is located above the debris collection box 304. The inclined side of the triangular protrusion 306 is flush with one side surface of the splash guard 3. The width of the lower side surface of the triangular protrusion 306 is slightly larger than the side wall thickness of the debris collection box 304. A first magnet block is fixedly connected to the side of the limiting plate 303 close to the debris collection box 304. A second magnet block is fixedly connected to the side of the debris collection box 304 away from the handle 305. The first magnet block and the second magnet block are magnetically connected. The triangular protrusion 306 is used to facilitate the debris splashed onto the splash guard 3 to flow into the debris collection box 304. The debris collection box 304 is used to collect debris and facilitate the removal of debris.

[0025] Furthermore, as shown in Figure 1 , four sliders 101 and a lead screw nut 102 are fixedly connected to the side of the main spindle box body 1 away from the vertical plate 2. A machine tool column 41 is arranged in the direction of the side of the main spindle box body 1 away from the vertical plate 2. Two slide rails 103 and a support seat 105 are fixedly connected to the side of the machine tool column 41 close to the main spindle box body 1. The two slide rails 103 correspond to the four sliders 101 and are slidably connected. A ball screw 106 is rotatably connected to the inner wall of the support seat 105. The ball screw 106 is threadedly connected to the lead screw nut 102. A first motor 104 is fixedly connected to the upper side surface of the machine tool column 41. The output end of the first motor 104 is fixedly connected to one end of the ball screw 106. By driving the ball screw 106 to rotate through the first motor 104, the ball screw 106 drives the lead screw nut 102 and the main spindle box body 1 to move up and down along the slide rail 103. The feed amount of the main spindle box body 1 for workpiece processing can be controlled by controlling the forward and reverse rotation of the first motor 104.

[0026] Still further, as shown in Figure 1 , a machine tool base 42 is fixedly connected to the lower side surface of the machine tool column 41. A horizontal movement mechanism 5 is connected to the upper side surface of the machine tool base 42. The horizontal movement mechanism 5 is located below the main spindle box body 1. The horizontal movement mechanism 5 is used to adjust the horizontal position of workpiece processing.

[0027] Even further, as shown in Figure 1As shown, on both sides of the machine tool base 42, there are fixedly connected with floor connection blocks 421. Threadedly connected to the floor connection blocks 421 are floor bolts 601. Rotatably arranged on the floor bolts 601 are floor support blocks 602. Threadedly connected to the floor bolts 601 are locking nuts 603. The lower side surface of the locking nuts 603 is in contact with the upper side surface of the floor connection blocks 421. Through the cooperation among the floor connection blocks 421, floor bolts 601, floor support blocks 602 and locking nuts 603, the machine tool base 42 is supported. After loosening the locking nuts 603, rotating the floor bolts 601 can adjust the height of the floor connection blocks 421. The triangular convex blocks 306 are used to facilitate the flow of the debris splashed onto the splash guard 3 into the debris collection box 304. The debris collection box 304 is used to collect debris and facilitate the removal of the debris.

[0028] As Figures 1 - 5 shown, the principle of the vertical numerical control machine tool with a debris splash guard provided in this embodiment is as follows: When using this vertical numerical control machine tool with a debris splash guard, the output end of the second motor 201 drives the gear 204 to rotate. The gear 204 drives the movable rack 203 to move on the support member 202. The movable rack 203 drives the fixing plate 301 to move. The fixing plate 301 drives the splash guard 3 to move. The splash guard 3 drives the U-shaped member 302 and the debris collection box 304 to move. Thus, by controlling the forward and reverse rotation of the second motor 201, the up and down movement of the splash guard 3 can be controlled. When the main spindle box body 1 processes a workpiece, it is convenient to use the splash guard 3 to block the debris generated during the workpiece processing. The first motor 104 drives the ball screw 106 to rotate. The ball screw 106 drives the screw nut 102 and the main spindle box body 1 to move up and down along the slide rail 103. The feed amount of the main spindle box body 1 for workpiece processing can be controlled by controlling the forward and reverse rotation of the first motor 104.
