[0020] In this utility model, the first direction is... Figure 1 The X direction in the middle, the second direction is... Figure 1 The Y-direction in the middle.

[0021] like Figures 1 to 3 As shown, an embodiment of the present invention provides a laser head mechanism, including a laser head 1, a support frame 2, a first rotary actuator 31, a second rotary actuator 41, a first housing 32 having a first internal space 321, and a second housing 42 having a second internal space 421. The laser head 1 is mounted on the support frame 2, and the first housing 32 is rotatably mounted on the support frame 2; The first rotary actuator 31 is installed in the first internal space 321 and connected to the support frame 2, and is used to drive the support frame 2 and the laser head 1 to rotate relative to the first housing 32 around a first direction; The second housing 42 is rotatably mounted on the first housing 32; The second rotary actuator 41 is installed in the second internal space 421 and connected to the first housing 32. It is used to drive the first housing 32, the support frame 2 and the laser head 1 to rotate relative to the second housing 42 around a second direction; wherein the first direction and the second direction are set at an angle.

[0022] The first rotary actuator 31 and the second rotary actuator 41 include, but are not limited to, motors, rotary cylinders, etc. Preferably, the first direction and the second direction are perpendicular.

[0023] In this invention, a first rotary actuator 31 is installed in the first internal space 321 of a first housing 32. The first housing 32 is rotatably mounted on a support frame 2. The first rotary actuator 31 is connected to the support frame 2, thereby enabling the first rotary actuator 31 to drive the support frame 2 and the laser head 1 to rotate around a first direction. A second rotary actuator 41 is installed in the second internal space 421 of a second housing 42. The second rotary actuator 41 is connected to the first housing 32, thereby enabling the second rotary actuator 41 to drive the first housing 32, the support frame 2, and the laser head 1 to rotate around a second direction. This laser head mechanism can adjust the rotation angle of the laser head 1 around the first and second directions, thereby meeting the needs of cutting at different bevel angles. In addition, the first rotary actuator 31 is embedded inside the first housing 32, and the second rotary actuator 41 is embedded inside the second housing 42, which avoids external dust and impurities from interfering with the first rotary actuator 31 and the second rotary actuator 41 during the operation and transportation of the laser head mechanism, thus extending the service life of the laser head mechanism; and the laser head mechanism has a compact structure, occupies little space, and is lightweight.

[0024] In one embodiment, such as Figure 1 and Figure 3 As shown, the support frame 2 includes a support plate 21 and a first side plate 22 and a second side plate 23 spaced apart on the support plate 21; a receiving space 24 is provided between the support plate 21, the first side plate 22 and the second side plate 23. The laser head 1 is mounted on the side of the support plate 21 away from the receiving space 24, the first housing 32 is rotatably mounted on the first side plate 22 and located in the receiving space 24, and the first rotary actuator 31 is connected to the side of the second side plate 23 facing the receiving space 24.

[0025] The first side plate 22 and the second side plate 23 are parallel, and the first side plate 22 is perpendicular to the support plate 21.

[0026] In this embodiment, the first housing 32 is located in the accommodating space 24 between the first side plate 22 and the second side plate 23. The first side plate 22 and the second side plate 23 can block the first internal space 321 from opposite ends, improving the compactness of the laser head mechanism. In addition, during the process of the first rotary actuator 31 driving the second side plate 23 to rotate around the first direction, the first side plate 22 also rotates around the first housing 32 in the first direction. Thus, the first side plate 22 and the second side plate 23 can support the support frame 2 on the first housing 32 from opposite ends, ensuring the stability of the support frame 2 rotating around the first direction.

[0027] In one embodiment, such as Figure 3 , Figure 4 as well as Figure 5 As shown, the laser head mechanism also includes a bearing 5. The first side plate 22 is provided with a first protrusion 221 on the side facing the receiving space 24. The first protrusion 221 is rotatably inserted into the first internal space 321 through the bearing 5. The second side plate 23 is provided with a first groove 231 on the side facing the receiving space 24, and the first housing 32 is provided with a first protrusion 322 at the end away from the first side plate 22. The first protrusion 322 is rotatably inserted into the first groove 231. The first side plate 22 and the second side plate 23 are used to block the first internal space 321 from opposite ends.

[0028] The inner ring of the bearing 5 is fitted onto the first protrusion 221, and the outer ring of the bearing 5 abuts against the inner wall of the first internal space 321, so that the first protrusion 221 is rotatably inserted into the first internal space 321 through the bearing 5.

[0029] In this embodiment, the first side plate 22 and the second side plate 23 can block the first internal space 321 from opposite ends, and the first protrusion 221 can support the first housing 32 through the bearing 5; the first protrusion 322 is rotatably inserted into the first groove 231, so that the first protrusion 322 can support the second side plate 23.

[0030] In one embodiment, such as Figure 2 and Figure 5 As shown, the laser head mechanism also includes a pressure cover 6, and an annular groove (not shown in the figure) is provided on the inner wall of the first internal space 321; the pressure cover 6 is installed on the first housing 32 and is used to limit the bearing 5 in the annular groove.

[0031] The first internal space 321 has a larger inner diameter at the annular groove, and the pressure cap 6 can axially limit the bearing 5 in the annular groove; the first protrusion 221 can be rotatably inserted into the inner hole of the bearing 5.

[0032] In this embodiment, the design of the pressure cap 6 facilitates the installation of the bearing 5 in the first internal space 321 and ensures the stability of the bearing 5 installed in the first internal space 321.

[0033] In one embodiment, such as Figure 4 and Figure 5As shown, the second side plate 23 is provided with a first arc-shaped groove 232 surrounding the first groove 231; the laser head mechanism also includes a first limiting member 324 installed on the first housing 32; the first limiting member 324 is slidably inserted into the first arc-shaped groove 232 to limit the rotation angle of the first housing 32 around the first direction.

[0034] The center of the first arc-shaped groove 232 coincides with the center of the first groove 231; the first limiting member 324 includes, but is not limited to, a cylinder, a bolt, etc.

[0035] Specifically, during the process of the first rotary actuator 31 driving the support frame 2 to rotate around the first direction, the first limiting member 324 slides in the first arc-shaped groove 232. When the opposite ends of the first arc-shaped groove 23 abut against the first limiting member 324, the support frame 2 can no longer rotate around the first direction. Thus, the first limiting member 324 and the first arc-shaped groove 232 can limit the rotation angle of the support frame 2 around the first direction, avoiding the accident of damage to the laser head 1 due to the excessive rotation angle of the support frame 2 around the first direction.

[0036] In one embodiment, such as Figure 4 As shown, the laser head mechanism also includes a first detector 71 and a first positioning member 72. The first detector 71 is mounted on the second side plate 23, and the first positioning member 72 is mounted on the end of the first housing 32 away from the first side plate 22. The first detector 71 is used to position the support frame 2 via the first positioning member 72.

[0037] The first detector 71 includes, but is not limited to, photoelectric sensors, laser sensors, etc.; the first detection element is provided with a first through slot through which the first positioning element 72 passes.

[0038] Specifically, when the first detector 71 detects the first positioning member 72, it indicates that the support frame 2 has rotated to the origin position around the first direction. The first rotary actuator 31 can stop driving the support frame 2 to rotate around the first direction, thus ensuring the reset accuracy of the support frame 2 when rotating around the first direction.

[0039] In one embodiment, such as Figure 5 As shown, the laser head mechanism further includes a second detector 81 and a second positioning element 82; the second detector 81 is mounted on the first housing 32, and the second positioning element 82 is mounted on the second housing 42; The second detector 81 is used to position the first housing 32 via the second positioning member 82.

[0040] The second detector 81 includes, but is not limited to, photoelectric sensors, laser sensors, etc.; the second detection element is provided with a second through groove through which the second positioning element 82 passes.

[0041] Specifically, when the second detector 81 detects the second positioning member 82, it indicates that the first housing 32 has rotated to the origin position around the second direction. The second rotary actuator 41 can then stop driving the first housing 32 to rotate around the second direction, thus ensuring the reset accuracy of the first housing 32 when rotating around the second direction.

[0042] In one embodiment, such as Figure 3 and Figure 4 As shown, the laser head mechanism further includes a second limiting member 423 mounted on the second housing 42, and a limiting part 325 disposed opposite to the second limiting member 423 on the first housing 32; the second limiting member 423 and the limiting part 325 are used to limit the rotation angle of the first housing 32 around the second direction.

[0043] The limiting part 325 includes, but is not limited to, an arc-shaped groove, a limiting protrusion, etc.; the second limiting member 423 includes, but is not limited to, a cylinder, a bolt, etc.

[0044] Specifically, during the process of the second rotary actuator 41 driving the first housing 32 to rotate around the second direction, when the limiting part 325 abuts against the first limiting member 324, the first housing 32 can no longer rotate around the second direction. Thus, the second limiting member 423 and the limiting part 325 can limit the rotation angle of the first housing 32 around the second direction, avoiding the accident of damage to the laser head 1 due to the excessive rotation angle of the second housing 42 around the second direction.

[0045] In one embodiment, such as Figure 3 As shown, the support frame 2 is provided with an angle scale 233, which is used to mark the rotation angle of the support frame 2 around the first direction.

[0046] In this embodiment, as Figure 1 As shown, the design of the angle scale 233 makes it easy for staff to identify the rotation angle of the support frame 2 around the first direction in a timely manner, thereby improving the user experience of the laser head mechanism.

[0047] In one embodiment, the laser head mechanism further includes a sealing plate 9, which is detachably mounted on the second housing 42 and is used to block the end of the second internal space 421 away from the first housing 32.

[0048] Another embodiment of this utility model provides a laser processing device, including the laser head mechanism described above.

[0049] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
