[0006] Preferably, a shielding mechanism is provided at the bottom of the laser cutting machine body. The shielding mechanism includes a second low rod, which is rotatably connected to the inside of the laser cutting machine body. A knob is fixedly connected to the surface of the second low rod, and a shielding plate is threadedly connected to the surface of the second low rod. The shielding plate is slidably connected to the inside of the laser cutting machine body.

[0007] Preferably, the laser cutting machine body rotates at the bottom of the spindle support via a movable rod, and the laser cutting machine body drives the laser generator head to rotate synchronously at the bottom of the spindle support.

[0008] Preferably, a threaded hole is formed on the surface of the movable rod, the first lead screw is threadedly connected to the threaded hole of the movable rod, the movable rod is in contact with the surface of the spindle support, and the first lead screw drives the movable rod to slide on the surface of the spindle support by rotation.

[0009] Preferably, the adjusting rod is provided in two sets. The moving rod supports the angle of the laser cutting machine body and the laser generator head through the adjusting rod. During the sliding process, the moving rod drives the laser cutting machine body to rotate at the bottom of the spindle support through the adjusting rod.

[0010] Preferably, the laser cutting machine body has a laser channel inside, and a guide chamber is provided at the bottom of the laser channel of the laser cutting machine body, and the second low rod slides on the guide chamber of the laser cutting machine body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The output shaft of the motor drives the first lead screw to rotate. The first lead screw drives the moving rod to slide and rise on the surface of the main spindle support through rotation. During the rising and falling process, the moving rod drives the laser cutting machine body and the laser generator head to rotate at the bottom of the main spindle support through the adjusting rod, thereby changing the angle of the laser cutting machine body and the laser generator head on the main spindle support, thus realizing the cutting of pipes at different angles, improving the flexibility of the main spindle device, and thus improving the flexibility of laser cutting.

[0014] 2. Before removing the laser generator head from the bottom of the laser cutting machine body, rotate the knob on the outside of the laser cutting machine body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A spindle assembly for a laser tube cutting machine includes a spindle support 1. A laser cutting machine body 11 is rotatably connected to the surface of the spindle support 1. A laser generator head 12 is fixedly mounted on the bottom of the laser cutting machine body 11. An adjustment mechanism is provided on the surface of the spindle support 1. The adjustment mechanism includes a movable rod 24, which is rotatably connected to the bottom of the spindle support 1. One end of the movable rod 24 away from the spindle support 1 is fixedly connected to the surface of the laser cutting machine body 11. A motor 2 is fixedly connected to the top of the spindle support 1. A first lead screw 21 is fixedly connected to the output shaft of the motor 2. A moving rod 22 is threadedly connected to the surface of the first lead screw 21. An adjustment rod 23 is rotatably connected to the surface of the moving rod 22. One end of the adjustment rod 23 away from the moving rod 22 is rotatably connected to the surface of the laser cutting machine body 11. This adjustment mechanism can adjust the angle between the laser cutting machine body 11 and the laser generator head 12 on the spindle support 1, thereby realizing the cutting of tubes at different angles, improving the flexibility of the spindle assembly, and thus improving the flexibility of laser cutting.

[0024] Furthermore, a shielding mechanism is provided at the bottom of the laser cutting machine body 11. The shielding mechanism includes a second low rod 3, which is rotatably connected to the inside of the laser cutting machine body 11. A knob 31 is fixedly connected to the surface of the second low rod 3, and a shielding plate 32 is threadedly connected to the surface of the second low rod 3. The shielding plate 32 is slidably connected to the inside of the laser cutting machine body 11. When the laser head 12 is disassembled for maintenance, the bottom of the laser cutting machine body 11 needs to be shielded to prevent dust from entering the inside of the laser cutting machine body 11 through the bottom of the laser cutting machine body 11. This shielding mechanism is easy to operate and does not require manual searching for objects to shield the bottom of the laser cutting machine body 11, thereby improving the efficiency of maintaining the laser head 12.

[0025] Furthermore, the laser cutting machine body 11 rotates at the bottom of the spindle support 1 via the movable rod 24. The laser cutting machine body 11 drives the laser generator head 12 to rotate synchronously at the bottom of the spindle support 1. The laser cutting machine body 11 and the laser generator head 12 change the cutting angle of the pipe by rotating, thereby improving the flexibility of the spindle device and thus improving the flexibility of laser cutting.

[0026] Furthermore, a threaded hole is formed on the surface of the moving rod 22, and the first lead screw 21 is threadedly connected to the threaded hole of the moving rod 22. The moving rod 22 is in contact with the surface of the spindle support 1. The first lead screw 21 drives the moving rod 22 to slide on the surface of the spindle support 1 by rotation. After the moving rod 22 slides, the first lead screw 21 will self-lock the moving rod 22, thereby ensuring the stability of the position of the moving rod 22. The moving rod 22 ensures the stability of the laser cutting machine body 11 and the laser generator head 12 through the adjusting rod 23, thereby ensuring the stability of the laser during the cutting process.

[0027] Furthermore, there are two sets of adjusting rods 23. The moving rod 22 supports the angle of the laser cutting machine body 11 and the laser generator head 12 through the adjusting rod 23. During the sliding process, the moving rod 22 drives the laser cutting machine body 11 to rotate at the bottom of the main shaft support 1 through the adjusting rod 23, thereby realizing the rotation of the laser cutting machine body 11 and the laser generator head 12. The two sets of adjusting rods 23 ensure effective support for the laser cutting machine body 11 after the angle is adjusted.

[0028] Furthermore, a laser channel is provided inside the laser cutting machine body 11, and multiple sets of lenses inside the laser cutting machine body 11 are located on the laser channel. A guide chamber is provided at the bottom of the laser channel of the laser cutting machine body 11. The second low rod 3 slides on the guide chamber of the laser cutting machine body 11. The second low rod 3 can slide to cover the laser channel at the bottom of the laser cutting machine body 11, thereby preventing dust from entering the interior of the laser channel and thus preventing dust from adhering to the lenses inside the laser cutting machine body 11.

[0029] Furthermore, a threaded hole is provided on the surface of the shielding plate 32, and the second low rod 3 is threadedly connected to the threaded hole of the shielding plate 32. The knob 31 drives the second low rod 3 to rotate outside the laser cutting machine body 11. The second low rod 3 drives the shielding plate 32 to slide on the guide cavity of the laser cutting machine body 11 by rotating. The second low rod 3 restricts the position of the shielding plate 32 inside the laser cutting machine body 11. The second low rod 3 can move the shielding plate 32 to the bottom of the laser channel of the laser cutting machine body 11.

[0030] Working principle: The laser cutting machine body 11 and the laser generator head 12 rotate at the bottom of the spindle support 1 via the movable rod 24. The output shaft of the motor 2 drives the first lead screw 21 to rotate. The first lead screw 21 drives the moving rod 22 to slide and rise on the surface of the spindle support 1 through rotation. During the rising and falling process, the moving rod 22 drives the laser cutting machine body 11 and the laser generator head 12 to rotate at the bottom of the spindle support 1 via the adjusting rod 23, thereby changing the angle of the laser cutting machine body 11 and the laser generator head 12 on the spindle support 1, thereby realizing the cutting of pipes at different angles, improving the flexibility of the spindle device, and thus improving the flexibility of laser cutting.

[0031] Before the laser head 12 is removed from the bottom of the laser cutting machine body 11, the knob 31 is rotated on the outside of the laser cutting machine body 11. The knob 31 drives the second low rod 3 to slide on the guide cavity at the bottom of the laser cutting machine body 11. The shielding plate 32 can slide to completely cover the laser channel of the laser cutting machine body 11 at the bottom, thus shielding the bottom of the laser cutting machine body 11. This eliminates the need to find an object to shield the laser head 12 after it is removed, making it convenient to maintain the laser head 12 and preventing dust from adhering to the lens inside the laser cutting machine body 11.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
