Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a laser cutting machine for square tube profiles. Background Art

[0002] ‌A laser cutting machine emits laser from a laser, which is focused into a laser beam with a high power density through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the melted or vaporized metal.

[0003] When the existing laser cutting machine cuts large square tube profiles, here it refers to cutting the holes on its surface. First, the square tube profile is fixed on the workbench, and the cutting head moves to cut its upper surface. After one side is cut, the operator uses external equipment to flip the square tube profile.

[0004] However, in the above method, flipping the square tube profile by external equipment has low work efficiency. In addition, the change of the cutting position is achieved by the movement of the cutting head. However, the square tube profile is relatively long, and the movement range of the cutting head is limited, so the position of the square tube profile needs to be adjusted, which reduces the work efficiency.

The clamps can clamp the four faces of the square tube profile 12, and the square tube profile 12 can move axially. A lifting table 3 is arranged on the bottom plate 5 at a position corresponding to the space between the pair of fixed seats 6. The driving and transmission assembly 4 is arranged on the lifting table 3 and can drive the square tube profile 12 to move horizontally. A first sliding member 21 is arranged at the bottom of the top plate 23 at a position corresponding to the space between the pair of fixed seats 6. A laser cutting head 22 is arranged at the moving end of the first sliding member 21, and the laser cutting head 22 can perform laser cutting on the upward-facing surface of the square tube profile 12. The clamp includes four linear motors 19, a mounting bracket 20, and rollers 14 that are arranged in a circular matrix on the disc 7. A slider 16 is arranged at the bottom of the mounting bracket 20.

The linear motor 19 is arranged on the disc 7, and its telescopic end is fixedly connected to the outer end of the mounting bracket 20. The four rollers 14 can limit the radial direction of the square tube profile 12, and the square tube profile 12 can move axially within the four rollers 14. The driving and rotating assembly includes a servo motor 9, a first pulley 10, a second pulley 11, and a belt 8. The servo motor 9 is arranged on the bottom plate 5, and its output end is connected to the first pulley 10. The second pulley 11 is annular, and its side wall is fixedly connected to the disc 7. The axis of the second pulley 11 is the same as that of the disc 7. The first pulley 10 and the second pulley 11 are connected by the belt 8.

A limiting ring 17 is arranged on the outer side wall of the disc 7, and a limiting groove 18 is provided on the inner side wall of the circular opening of the fixed seat 6. The limiting ring 17 is slidably connected to the limiting groove 18.

[0021] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the attached drawings of the specification Figures 1-3It can be known that when the utility model is working, the square tube profile 12 is inserted into the opening 13 of the disc 7, and the clamps on both sides apply pressure to the four sides of the square tube profile 12 to clamp it. The center line of the square tube profile 12 is the same as the axis of the disc 7. The laser cutting head 22 connected by the first sliding member 21 under the top plate 23 can perform laser cutting on the upward side of the square tube profile 12. Since the clamp can clamp the four sides of the square tube profile 12, and the square tube profile 12 can move axially, the driving transmission assembly 4 on the lifting platform 3 on the bottom plate 5 can adjust the horizontal position of the square tube profile 12 to cooperate with the cutting of the laser cutting head 22. Since the disc 7 can rotate in the circular opening of the fixed seat 6, the driving rotation assembly can drive the disc 7 and the square tube profile 12 in the clamp to rotate and turn over, thereby improving the convenience of adjusting the processing position of the square tube profile 12, thereby improving the processing efficiency.

[0023] The fixture includes four groups of linear motors 19, mounting frames 20 and rollers 14 distributed in a circular matrix on the disc 7. A slider 16 is provided at the bottom of the mounting frame 20. A slide groove 15 is radially provided on the disc 7. The slider 16 is slidably connected to the slide groove 15 to ensure the stability of movement. The roller 14 is rotatably arranged at one end of the inner side of the mounting frame 20. The linear motor 19 is arranged on the disc 7. The telescopic end is fixedly connected to one end of the outer side of the mounting frame 20. The four groups of rollers 14 can limit the radial direction of the square tube profile 12, and the square tube profile 12 can move axially in the four groups of rollers 14. When working, the linear motor 19 on the disc 7 drives the mounting frame 20 to move radially inward, thereby driving the rollers 14 evenly distributed on the disc 7 to clamp and limit the square tube profile 12 radially. The rollers 14 are designed so as not to affect the axial movement of the square tube profile 12.

[0024] The driving rotating assembly includes a servo motor 9, a first pulley 10, a second pulley 11 and a belt 8. The servo motor 9 is arranged on the bottom plate 5, and the output end is connected to the first pulley 10. The second pulley 11 is annular, and the side wall is fixedly connected to the disc 7. The second pulley 11 has the same axis as the disc 7, and the first pulley 10 and the second pulley 11 are connected through the belt 8. When working, the servo motor 9 drives the first pulley 10 to rotate, and drives the second pulley 11 to rotate through the belt 8, thereby driving the disc 7 to rotate, thereby turning the square tube profile 12 between the clamps on the disc 7. Here, it is limited that the servo motor 9 drives the square tube profile 12 to turn 180 degrees forward and backward. Note that during installation, it is necessary to ensure that the length of the connecting line of the linear motor 19 is sufficient.
