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

[0026] Embodiment

[0027] A numerical control boring and milling machine protective cover convenient for collecting chips, as Figures 1-8 shown, includes a protective cover body 1; the protective cover body 1 includes two side walls, a front wall and a rear wall; the side walls include a first sheet metal 3; the first sheet metal 3 is inclined and is bent to form a U-shaped groove 4 at a position near the low end of the machine tool body.

[0028] The above-mentioned numerically controlled boring and milling machine protective cover that facilitates chip collection is provided with a bottomed protective cover and a U-shaped groove 4 that can collect chips and cutting fluid. The chips and cutting fluid fall on the inclined surface of the inclined 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 environmental pollution, and is convenient for cleaning. The protective cover is placed on the foundation or the ground by relying on the support legs 8 and is not fixedly connected to the machine tool body. Therefore, the protective cover can be moved parallel from both sides, and the installation is convenient and fast.

[0029] 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 when the chip conveyor 2 is turned on, the chips can be discharged to the discharge port at one end of it.

[0030] Specifically, it further 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; one end of the first sheet metal 3 close to the U-shaped groove 4 is fixedly connected with a transition plate 17; one ends of the transition plate 17 and the fixed sheet metal 18 respectively extend above the two guide plates at the top of the chip conveyor 2. The fixed sheet metal 18 and the transition plate 17 play a role in guiding materials and can prevent chips and cutting fluid from falling into the gap between the U-shaped groove 4 and the chip conveyor 2.

[0031] Specifically, one end of the first sheet metal 3 away from the machine tool body is provided with a bending part and is fixedly connected to the third sheet metal 9 through the bending part; several U-shaped tenth sheet metals 6 arranged at intervals are fixedly connected to the bottom of the first sheet metal 3; a second sheet metal 7 is fixedly connected to one side of the bottom of the first sheet metal 3 where the U-shaped groove 4 is located; 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 fixedly connected with a support frame 10 with a right trapezoidal cross section; the inclined surface of the support frame 10 is fixedly connected to the bottom of the tenth sheet metal 6, the top surface is fixedly connected to the bottom of the third sheet metal 9, and the side surface is fixedly connected to the outer wall of the second sheet metal 7; support legs 8 are fixedly connected to 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 U-shaped groove 4.

The wall thickness of traditional square steel and angle steel is relatively thick and the weight is relatively large. Therefore, using thin sheets to make the protective cover can effectively reduce the weight of the protective cover. The bending parts formed by bending on each sheet metal are connected to each other. On the one hand, it can increase the connection area and improve the connection strength. On the other hand, the bending parts play the role of reinforcing ribs, which can effectively improve the strength of the entire protective cover.

[0035] Specifically, floor bolts 5 are threadedly installed at the bottom of the support legs 8. By rotating the floor bolts 5, the effective height of the floor bolts 5 can be adjusted to adapt to an uneven ground.

[0036] Specifically, a drain hole is opened at the bottom of the chip conveyor 2; a filter water tank is placed below the drain hole or the drain hole is the catch basin of the foundation. The cutting fluid penetrates from the surface of the chip conveyor 2 to the bottom, and then is discharged from the drain hole into the filter water tank or directly into the catch basin.

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

[0038] The working principle of the present utility model:

[0039] The chips and the 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. By turning on the chip conveyor 2, the chips can be discharged to the discharge port at one end. The cutting fluid penetrates from the surface of the chip conveyor 2 to the bottom, and then is discharged from the drain hole into the filter water tank or directly into the catch basin. The structure of the present utility model is simple, which can effectively prevent the chips and the cutting fluid from falling on the ground, avoid polluting the environment, and is convenient for cleaning. The protective cover is placed on the foundation or the ground by relying on the support legs 8 and is not fixedly connected to the machine tool main body.
