[0001] The invention belongs to the technical field of aluminum alloy laser cutting, and in particular relates to a numerical control laser cutting device for aluminum alloy plate processing. Background Art

[0002] Aluminum alloy sheets are important materials widely used in aerospace, automobile manufacturing, machinery manufacturing and other fields. In industrial production, aluminum alloy sheets need to be cut to meet the needs of different fields. Traditional aluminum alloy sheet cutting machines can only perform straight line cutting at the same angle on aluminum alloy sheets, which cannot meet the cutting needs of different shapes.

[0003] CN220427189U discloses an aluminum alloy plate cutting machine, including a base, and side panels are fixedly connected to the left and right sides of the top of the base. The aluminum alloy plate cutting machine places the aluminum alloy plate to be cut inside the placement seat, and then starts the electric push rod to drive the laser cutting head to move down for laser cutting. When the front and rear cutting positions need to be changed, the pull handle on the front side of the placement seat can be pulled to adjust, and when the left and right cutting positions need to be changed, the forward and reverse manual turning structure drives the threaded rod to rotate forward and backward. At this time, the threaded strip on the outside of the threaded rod contacts the threaded groove provided on the inner side wall of the threaded block. By setting a limit slider to limit the position of the threaded block, the threaded block can be driven to move left and right, and then the fixed frame, the electric push rod and the laser cutting head can be synchronously driven to move left and right, and the position can be changed in time according to the situation, so as to achieve the purpose of manually controlling the cutting position as a whole.

[0017] 3. By setting up a protective cover, the debris generated by the processing is concentrated in the protective cover, and the debris enters the chip guide pipe through the chip suction pipe.

The output ends of the two sets of the second motors 10027 are both transmission-connected with screw rods 10028, and the two sets of screw rods 10028 are both threadedly connected with internal thread blocks 10029. The two sets of internal thread blocks 10029 are respectively fixedly connected with the bottom ends of the two sets of clamping blocks 10025; Specifically, the aluminum alloy plate is placed on the carrier plate 10024, and two groups of second motors 10027 are controlled to drive two groups of clamping blocks 10025 to move horizontally, so that the two groups of clamping blocks 10025 are respectively clamped with the two ends of the aluminum alloy plate to complete the clamping of the aluminum alloy plate. The two groups of second motors 10027 drive the two groups of clamping blocks 10025 to move in the same direction at the same speed to achieve the movement of the position of the aluminum alloy plate.

[0032] The working principle of the CNC laser cutting device for aluminum alloy plate processing proposed by the present invention is as follows: The aluminum alloy plate is placed on a carrier plate 10024, and two groups of second motors 10027 are controlled to drive two groups of clamping blocks 10025 to move horizontally, so that the two groups of clamping blocks 10025 are respectively clamped with the two ends of the aluminum alloy plate to complete the clamping of the aluminum alloy plate. The two groups of second motors 10027 drive the two groups of clamping blocks 10025 to move in the same direction at the same speed to achieve the movement of the position of the aluminum alloy plate.

The first motor 6011 drives the first electric slide 6081 to rotate and adjust the cutting angle. When the first electric slide 6081 rotates to a preset angle, the laser cutting knife 6083 is driven horizontally by the first electric slide 6081 to cut the aluminum alloy plate, so that the device can perform straight-line cutting operations at different preset angles on the aluminum alloy plate. The laser cutting knife 6083 is driven horizontally by the first electric slide 6081 to adjust the position of the laser cutting knife 6083. When the position of the laser cutting knife 6083 is adjusted to the preset position, the first motor 6011 drives the first electric slide 6081 to rotate, so that the laser cutting knife 6083 performs rotary cutting of the aluminum alloy plate with a preset inner diameter, so that the device can perform circular cutting of the aluminum alloy plate with different preset inner diameters, thereby meeting different processing requirements of the aluminum alloy plate.

[0034] By setting up the protective cover 603, the debris generated by the processing is concentrated in the protective cover 603, and the debris is allowed to enter the chip guide pipe 8 through the chip suction pipe 604. The air in the chip collecting box 7 is sucked out by the vacuum pump to generate negative pressure in the chip collecting box 7, so that the debris generated by the cutting process enters the chip collecting box 7 through the chip guide pipe 8, effectively avoiding the debris generated during the processing of the aluminum alloy plate from splashing and causing environmental pollution.

[0035] After the aluminum alloy plate is cut, it is separated into the finished product sucked by the vacuum suction cup 609 and the scraps clamped by the clamping mechanism 1002. The finished product is moved upward by the vacuum suction cup 609 to separate the finished product from the scraps. The clamping mechanism 1002 is driven to move toward one end of the waste box 11 by two sets of second electric slides 1001. The finished product is dropped into the finished product box 9 through the guide groove 101 by closing the vacuum suction cup 609. For collection, when the clamping mechanism 1002 drives the scraps to move to the tooth plate 1003, the two sets of gears 10022 are respectively meshed and connected with the two sets of tooth plates 1003, so that the second linkage block 10021 moves and flips at the same time, and the two sets of second motors 10027 respectively drive the two sets of clamping blocks 10025 to move in opposite directions, so that they are respectively separated from the two ends of the scraps, and the scraps remaining on the clamping mechanism 1002 slide into the waste box 11 for centralized treatment.
