In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Example

[0027] A protective cover for a large CNC machine tool, such as Figure 1-8 As shown, it includes a protective cover body 1, which includes two side walls, a front wall, a rear wall and a bottom; the bottom includes two first sheet metals 3; one end of the first sheet metal 3 is provided with a bending portion; the side wall of the protective cover body 1 includes a third sheet metal 9 fixedly connected to the bending portion of the first sheet metal 3; the upper and lower ends of the third sheet metal 9 are both provided with L-shaped bending portions; the rear wall and side walls of the protective cover body 1 both include a plurality of sheet metals with L-shaped bending portions at the upper and lower ends, and the bending portions of adjacent sheet metals are embedded and fixedly connected.

[0028] The above-mentioned large CNC machine tool protective cover has a main body 1 of the protective cover that is provided with a bottom, which can catch chips and cutting fluid, prevent chips and cutting fluid from falling on the ground, avoid polluting the environment, and is easy to clean; the side walls and the rear wall are connected by a plurality of sheet metals with L-shaped bends at the upper and lower ends, and the bends of adjacent sheet metals are embedded and fixed to form reinforcing ribs. Compared with the traditional protective cover made of square steel and angle steel, the overall weight is greatly reduced while ensuring the strength and rigidity. The protective cover is not fixedly connected to the main body of the machine tool, so the protective cover can be moved in parallel from both sides, and the installation is convenient and quick.

[0029] Specifically, the upper end bending portion of the third sheet metal 9 is embedded and fixedly connected with the lower end bending portion of the fourth sheet metal 11; the upper end bending portion of the fourth sheet metal 11 is embedded and fixedly connected with the lower end bending portion of the fifth sheet metal 12; the upper end bending portion of the fifth sheet metal 12 is embedded and fixedly connected with the lower end bending portion of the eighth sheet metal 15; the upper end bending portion of the eighth sheet metal 15 is fixedly connected with the lower end of the ninth sheet metal 16.

[0030] Specifically, in order to facilitate observation of the processing of the internal parts of the protective cover, the sixth sheet metal 13 is fixedly connected to the upper and lower parts of the inner wall of the fifth sheet metal 12, and the seventh sheet metal 14 is fixedly connected between the two sixth sheet metals 13; observation windows are installed on the fifth sheet metal 12 and the seventh sheet metal 14.

[0031] Specifically, the bottom of the first sheet metal 3 is fixed with a plurality of interval-arranged tenth sheet metals 6 with U-shaped cross sections; the bottom of the first sheet metal 3 is fixed with a second sheet metal 7 with U-shaped cross sections; the top of the open end of the tenth sheet metal 6 is fixedly connected to the bottom of the first sheet metal 3; the bottom of each tenth sheet metal 6 is fixed with a support frame 10 with a right-angle trapezoidal cross section; the inclined surface of the support frame 10 is fixed with the bottom of the tenth sheet metal 6, the top surface is fixed with the bottom of the third sheet metal 9, and the side surface is fixed with the outer wall of the second sheet metal 7; the bottom of the end of the support frame 10 away from the machine tool body, the bottom of the second sheet metal 7, and the bottom of the first sheet metal 3 close to the machine tool body are all fixed with support legs 8. The arrangement of the tenth sheet metal 6, the second sheet metal 7, the third sheet metal 9 and the support frame 10 can effectively improve the anti-deformation ability of the first sheet metal 3, and with the use of the support legs 8, the weight of the entire protective cover can be shared.

[0032] Specifically, the bottom of the supporting legs 8 are all threadedly mounted with the foot 5. The effective height of the foot 5 can be adjusted by rotating the foot 5, so as to adapt to the uneven ground.

[0033] Specifically, the first sheet metal 3 is tilted, and the side close to the machine tool body is a relatively low end; the end of the first sheet metal 3 close to the machine tool body is provided with a U-shaped groove 4. The chips and cutting fluid fall on the inclined surface of the tilted first sheet metal 3, and gradually slide into the U-shaped groove 4 for collection, which can effectively prevent the chips and cutting fluid from falling on the ground, avoid polluting the environment, and facilitate cleaning.

[0034] Specifically, in order to facilitate the discharge of chips, a chip conveyor 2 is placed in the U-shaped groove 4. The chips fall on the chip conveyor 2, and the chip conveyor 2 is turned on to discharge the chips to the discharge port at one end thereof.

[0035] Specifically, it also includes a fixed sheet metal 18 with an L-shaped cross section; the fixed sheet metal 18 is fixedly installed on the machine tool body; a transition plate 17 is fixedly connected to one end of the first sheet metal 3 close to the U-shaped groove 4; one end of the transition plate 17 and the fixed sheet metal 18 respectively extend above the two side guide plates on the top of the chip conveyor 2. The fixed sheet metal 18 and the transition plate 17 play a role in guiding materials, which can prevent chips and cutting fluid from falling into the gap between the U-shaped groove 4 and the chip conveyor 2.

[0036] Specifically, a drainage hole is provided at the bottom of the chip conveyor 2; a filtered water tank is placed below the drainage hole or a water collection ditch is placed below the drainage hole. The cutting fluid penetrates from the surface of the chip conveyor 2 to the bottom, and then is discharged from the drainage hole into the filtered water tank or directly into the water collection ditch.

[0037] Specifically, a sliding door is slidably installed on the front wall of the protective cover body 1.

[0038] Working principle of the embodiment:

[0039] Chips and cutting fluid fall on the inclined surface of the inclined first sheet metal 3, and gradually slide onto the chip conveyor 2 in the U-shaped groove 4. When the chip conveyor 2 is turned on, the chips can be discharged to the discharge port at one end thereof. The cutting fluid penetrates from the surface of the chip conveyor 2 to the bottom, and then is discharged from the drainage hole into the filter water tank or directly into the sump. The rear wall and side walls of the protective cover body are connected by a plurality of sheet metals with L-shaped bends at the upper and lower ends, and the bends of adjacent sheet metals are embedded and fixed to form reinforcing ribs. Compared with the traditional protective cover made of square steel and angle steel, the overall weight is greatly reduced while ensuring strength and stiffness. The protective cover is not fixedly connected to the machine tool body, so the protective cover can be moved parallel to both sides, and the installation is convenient and quick.
