[0001] The utility model relates to the technical field of laser tube cutting, in particular to a laser cutting head drive component and a laser tube cutting machine. Background Art

[0002] When the laser tube cutting machine is used to cut the tube, the drive assembly drives the laser cutting head to rotate around the outer circumference of the tube.

At present, the drive assembly drives the laser cutting head to move and rotate relative to the tube. However, for tubes with complex shapes, the drive assembly needs to frequently change the distance between the laser cutting head and the tube during the process of driving the laser cutting head to rotate around the outer circumference of the tube, resulting in a large load on the drive assembly, which affects the accuracy of the drive assembly driving the laser cutting head to move.

[0031] Reference Figure 1 to Figure 2 The laser cutting head drive assembly of the utility model is implemented as follows:

[0032] The laser cutting head driving assembly includes a driving turntable 100, a first driving mechanism 200, a second driving mechanism 300, a third driving mechanism 400, and a laser cutting head.

[0033] The driving turntable 100 rotates around an axis extending in the front-rear direction. The driving turntable 100 is connected to the first driving mechanism 200 , and the driving turntable 100 drives the first driving mechanism 200 to rotate.

[0034] The first driving mechanism 200 is connected to the second driving mechanism 300 . The driving direction of the first driving mechanism 200 is up and down. The first driving mechanism 200 drives the second driving mechanism 300 to move up and down.

[0035] The second driving mechanism 300 is connected to the third driving mechanism 400 . The driving direction of the second driving mechanism 300 is perpendicular to the driving direction of the first driving mechanism 200 . The second driving mechanism 300 drives the third driving mechanism 400 to move left and right.

[0036] The third driving mechanism 400 is connected to the laser cutting head. The driving direction of the third driving mechanism 400 is parallel to the driving direction of the first driving mechanism 200. The third driving mechanism 400 drives the laser cutting head to move up and down.

[0037] The driving turntable 100 drives the first driving mechanism 200 to rotate, and the position of the laser cutting head is adjusted through the first driving mechanism 200 and the second driving mechanism 300. Finally, the laser cutting head is frequently moved through the third driving mechanism 400, and the distance between the laser cutting head and the pipe is frequently and accurately changed, thereby reducing the driving action of the first driving mechanism 200, thereby reducing the load of the first driving mechanism 200. The third driving mechanism 400 can frequently drive the lighter laser cutting head to move, and the load of the third driving mechanism 400 is less, which helps to improve the accuracy of the movement of the laser cutting head.

[0038] In some embodiments, the stroke of the laser cutting head driven up and down by the third driving mechanism 400 is smaller than the stroke of the second driving mechanism 300 driven up and down by the first driving mechanism 200.

[0039] After the first driving mechanism 200 with a long stroke moves the laser cutting head to the vicinity of the target position, the laser cutting head is moved by the third driving mechanism 400 with a short stroke, which helps to reduce the weight of the third driving mechanism 400 itself and reduce the driving power of the third driving mechanism 400.

[0040] In some embodiments, the first driving mechanism 200 and the third driving mechanism 400 are both driven by screws.

[0041] The screw drive has a high precision, which helps the first drive mechanism 200 and the third drive mechanism 400 to drive the laser cutting head to move accurately.

[0042] In some embodiments, the second driving mechanism 300 is arranged above the rotation axis of the driving turntable 100, and the third driving mechanism 400 is connected to the second driving mechanism 300, and the laser cutting head is connected to the third driving mechanism 400, then all three are located above the rotation axis of the driving turntable 100, and the counterweight block 500 is arranged below the rotation axis of the driving turntable 100.

[0043] The second driving mechanism 300 , the third driving mechanism 400 , the laser cutting head, and the counterweight 500 are reasonably distributed on the driving turntable 100 , balancing the forces on the upper and lower sides of the driving turntable 100 , so that the driving turntable 100 rotates more smoothly.

[0044] In some embodiments, the first driving mechanism 200 is provided with a first slide rail 210, a first motor 220, and a first transmission member 230. The first slide rail 210 extends in the up and down directions. The two first slide rails 210 are distributed in parallel on the left and right sides of the rotation axis of the driving turntable 100. Each first slide rail 210 is provided with a first slider that slides up and down. The first slider is connected to the second driving mechanism 300. The first transmission member 230 is a screw transmission member. The first motor 220 is connected to the first transmission member 230. The first transmission member 230 is connected to one of the first sliders. The first motor 220 rotates to make the first transmission member 230 drive the first slider to slide up and down, thereby making the second driving mechanism 300 move up and down.

[0045] Symmetrically distributing the two first slide rails 210 on the left and right sides of the rotation axis of the driving turntable 100 helps to balance the forces on the left and right sides of the driving turntable 100, so that the driving turntable 100 rotates more smoothly.

[0046] In some embodiments, the first motor 220 and the first transmission member 230 are located to the left of the rotation axis of the driving turntable 100 , and the second driving mechanism 300 is provided with a second motor 320 , which is located to the right of the rotation axis of the driving turntable 100 .

[0047] This helps to balance the forces on the left and right sides of the driving turntable 100 , making the driving turntable 100 rotate more smoothly.

[0048] In some embodiments, the second driving mechanism 300 is composed of a second slide rail 310 and a second transmission member 330. The second slide rail 310 extends left and right, and the two second slide rails 310 are distributed parallel to each other up and down. The left and right ends of the two second slide rails 310 are respectively slidably connected to the first slide rail 210 of the first driving mechanism 200, and the third driving mechanism 400 is slidably connected to the two second slide rails 310.

[0049] The upper and lower sides of the third driving mechanism 400 are respectively connected by two second slide rails 310, so that the left and right movement of the third driving mechanism 400 is more stable, and the third driving mechanism 400 is prevented from tilting downward or upward.

[0062] Reference Figure 1 to Figure 2 The laser tube cutting machine of the utility model is implemented as follows:

[0063] The laser tube cutting machine includes the above-mentioned laser cutting head drive assembly.

[0064] The driving turntable 100 drives the first driving mechanism 200 to rotate, and the position of the laser cutting head is adjusted through the first driving mechanism 200 and the second driving mechanism 300. Finally, the laser cutting head is frequently moved through the third driving mechanism 400, and the distance between the laser cutting head and the pipe is frequently and accurately changed, thereby reducing the driving action of the first driving mechanism 200, thereby reducing the load of the first driving mechanism 200.

[0066] By adjusting the upper and lower positions of the driving turntable 100 through the adjustment mechanism 700, the rotation axis of the driving turntable 100 is brought close to the center of the pipe, which helps to reduce the distance that the first driving mechanism 200 and the third driving mechanism 400 drive the laser cutting head to move, thereby improving the efficiency of the laser cutting head in cutting the pipe.
