Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, in particular to a small-format laser cutting machine head structure and a laser cutting machine. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] The existing laser cutting machine head has no protection and is prone to malfunction when hit by external forces, resulting in an inability to continue cutting, increasing maintenance costs and affecting production efficiency. Utility Model Content

[0010] The beneficial effects of the utility model are:

[0011] 1. After the laser head body of the utility model stops being used, it can be protected by the first protective cover, the second protective cover and the sealing plate to avoid damage to the laser head body by external forces and reduce maintenance costs.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example 1

[0020] like Figure 2 、 Figure 3 and Figure 4 The head structure of the small-format laser cutting machine shown includes a laser head mounting part 1, a laser head body 2 is fixedly mounted on the bottom of the laser head mounting part 1, the outer ring of the laser head body 2 is provided with a first protective sleeve 3, the first protective sleeve 3 is fixedly connected to the laser head mounting part 1, the outer ring movable sleeve of the first protective sleeve 3 is provided with a second protective sleeve 6, the tail end of the second protective sleeve 6 is hinged with a sealing plate 12 through a rebound assembly, and the diameter of the sealing plate 12 is larger than the inner ring diameter of the second protective sleeve 6.

[0021] The lengths of the first protective cover 3 and the second protective cover 6 are both shorter than the length of the laser head body 2. When the second protective cover 6 reaches the very end of the first protective cover 3, the combined length of the first protective cover 3 and the second protective cover 6 is greater than the length of the laser head body 2, so that the first protective cover 3, the second protective cover 6 and the sealing plate 12 can completely enclose the laser head body 2.

[0022] Specifically, the cooperation between the first protective cover 3 and the second protective cover 6 enables them to shrink freely. When the laser head body 2 stops cutting, the second protective cover 6 is moved to the tail end of the first protective cover 3. At this time, the sum of the lengths of the first protective cover 3 and the second protective cover 6 is greater than the length of the laser head body 2. The cooperation of the sealing plate 12 will completely seal the laser head body 2 to protect the laser head body 2. When the laser head body 2 is required to perform cutting operations, the second protective cover 6 is pulled upwards. At the same time, the laser head body 2 will push open the sealing plate 12 to expose the laser head body 2 for cutting operations.

[0023] like Figure 2 and Figure 4 As shown, the rebound assembly includes a fixed seat 9 fixed on the tail end of the second protective sleeve 6, the fixed seat 9 is rotatably connected to the connecting block 11 through the rotating shaft 10, the connecting block 11 is fixedly connected to the sealing plate 12, and an elastic member 13 is fixedly connected between the fixed seat 9 and the connecting block 11, the elastic member 13 is a torsion spring, and is sleeved on the outer ring of the rotating shaft 10.

[0024] Specifically, when the second protective cover 6 approaches the laser head mounting part 1, the laser head body 2 will push open the sealing plate 12, causing the sealing plate 12 to rotate around the rotating shaft 10. When the second protective cover 6 comes to the tail end of the first protective cover 3 again, the force of the elastic member 13 will push the sealing plate 12 to close the opening at the tail end of the second protective cover 6 to prevent dust from entering the holes of the laser head body 2.

[0025] like Figure 2 and Figure 3 As shown, a guide slot 5 is provided on the outer wall of the first protective sleeve 3 , and a guide slider 8 is fixedly connected to the inner wall of the second protective sleeve 6 , and the guide slider 8 is slidably connected to the guide slot 5 .

[0026] It should be noted that the sliding cooperation between the guide slider 8 and the guide groove 5 makes it impossible for the second protective sleeve 6 to be separated from the first protective sleeve 3. At the same time, the second protective sleeve 6 can only move on the outer ring of the first protective sleeve 3 along the track of the guide groove 5 and cannot rotate on the outer ring of the first protective sleeve 3.

[0027] like Figure 2 As shown, one end of the first protective cover 3 away from the second protective cover 6 is fixedly connected to the first magnet 4 , and one end of the second protective cover 6 close to the first protective cover 3 is fixedly connected to the second magnet 7 .

[0028] Specifically, when the second protective cover 6 approaches the laser head mounting part 1, the second protective cover 6 can be suspended at the bottom of the laser head mounting part 1 through the magnetic attraction of the first magnet 4 and the second magnet 7, so as to facilitate the cutting operation of the laser head body 2.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, the laser cutting machine, compared with embodiment 1, this embodiment includes an operating table 14, the top of the operating table 14 is fixedly connected to a placement table 15, the top of the placement table 15 is fixedly connected to a cross slide 16, the cross slide 16 is installed with the above-mentioned small-format laser cutting machine head structure, and the laser head mounting part 1 can be movably installed on the cross slide 16.

[0031] Specifically, the workpiece is placed on the platform 15 and cut by the laser head body 2. The cross slide 16 drives the laser head body 2 to move along the X and Y axes. The operator can change the position of the laser head body 2 according to actual needs.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
