Steel components have comprehensive advantages such as simple structure, fast installation, short construction period, and good seismic performance. They are widely used in industries such as building construction and railway construction.

[0003] At present, during the production process of steel components, the raw materials need to be cut and processed. In the prior art, manual cutting guns are mostly used for melting cutting. However, with the advancement of major projects such as railway construction, bridge construction, water conservancy construction, hydropower construction, energy, mine construction, and construction industry in China, the demand in the domestic steel structure market has increased year by year, and manual cutting can no longer meet the current production requirements of high efficiency and low energy consumption.

[0004] For existing three-axis laser cutting equipment for steel components, when performing oblique cutting on the side of a steel component, the cooperation of a two-axis translation mechanism is usually required to achieve oblique cutting, and the accuracy of the cutting surface is related to the accuracy of the translation mechanism.

The third gear 206 is arranged at the output end of the fifth driver 207, and the third gear 206 meshes with the second rack 205. The fifth driver 207 is used to drive the third gear 206 to rotate to drive the second moving frame 204 to move along the second guide rail 202.

[0059] As Figure 6 and Figure 9As shown, the Z-axis moving mechanism 3 includes a third guide rail 301, a third slider 302, a third moving frame 303, a third rack 304, a fourth gear 305, and a sixth driver 306. The third guide rail 301 and the third rack 304 are both arranged on the second moving frame 204 and are arranged along the Z-axis direction. The third moving frame 303 is arranged on the third guide rail 301 through the third slider 302. The sixth driver 306 is arranged on the third moving frame 303. The fourth gear 305 is arranged at the output end of the sixth driver 306, and the fourth gear 305 meshes with the third rack 304. The sixth driver 306 is used to drive the fourth gear 305 to rotate, so as to drive the third moving frame 303 to move along the third guide rail 301.

[0060] As Figure 6 and Figure 8 shown, in this embodiment, the first angle adjustment mechanism 4 is arranged on the third moving frame 303. The first angle adjustment mechanism 4 includes two parts: a first rotating seat 4a and a worm and gear drive mechanism 4b. Specifically, the first rotating seat 4a includes a first base 401 and a turntable 402. The first base 401 is arranged on the third moving frame 303. The turntable 402 is rotatably arranged on the first base 401, and the turntable 402 can rotate in the Y-Z plane. The worm and gear drive mechanism 4b includes a worm wheel 403, a worm 404, and a first driver 405. The worm wheel 403 is arranged on the outer side of the turntable 402. The worm 404 is rotatably arranged on the third moving frame 303 through a first mounting bracket 406. The first driver 405 is arranged on the third moving frame 303, and the output end is connected to the worm 404. The worm 404 and the worm wheel 403 mesh. The first driver 405 is used to drive the worm 404 to rotate, so as to drive the turntable 402 to rotate in the Y-Z plane.

[0061] In this embodiment, a first translation mechanism 8 is arranged on the turntable 402. A two-axis adjustment mechanism 9 is arranged on the first translation mechanism 8, and the laser cutting mechanism 6 is arranged on the two-axis adjustment mechanism 9. The first translation mechanism 8 is used to drive the laser cutting mechanism 6 and the two-axis adjustment mechanism 9 to translate in the Y-Z plane, and the two-axis adjustment mechanism 9 is used to adjust the horizontal angle and inclination angle of the laser cutting mechanism 6 (the horizontal angle and inclination angle refer to the horizontal angle and inclination angle when the first angle adjustment mechanism 4 is in the initial state. If the first angle adjustment mechanism 4 rotates, the reference plane of the horizontal angle and inclination angle also changes accordingly).

[0062] Specifically, the first translation mechanism 8 includes a first mounting plate 801, a fourth guide rail 802, a fourth slider 803, a lead screw 804, a seventh driver 805, and a fourth moving frame 806. The first mounting plate 801 is disposed on the turntable 402. The fourth guide rail 802 is disposed on the first mounting plate 801. The lead screw 804 is rotatably disposed on the first mounting plate 801 and is parallel to the fourth guide rail 802. The seventh driver 805 is disposed on the first mounting plate 801, and the output end of the seventh driver 805 is connected to the lead screw 804. The fourth moving frame 806 is disposed on the fourth guide rail 802 through the fourth slider 803. A nut that cooperates with the lead screw 804 is disposed on the fourth moving frame 806.

[0063] As Figure 7 and Figure 11 shown, in this embodiment, the second angle adjustment mechanism 5 is composed of a second rotating seat 5a and a second gear-rack drive mechanism 5b. Specifically, the second rotating seat 5a includes a second base 501 and a hinge seat 502. The second base 501 is disposed on the first moving frame 104. The hinge seat 502 is rotatably disposed on the second base 501. The tooling platform 7 is disposed on the hinge seat 502. Side frames 503 are disposed on both sides of the bottom of the tooling platform 7. The two side frames 503 are symmetric with respect to the hinge seat 502, and both of the two side frames 503 are arc-shaped. The center of the arc coincides with the rotation axis of the hinge seat 502. The second gear-rack drive mechanism 5b includes an arc-shaped rack 504, a first gear 505, and a second driver 506. The arc-shaped rack 504 is disposed on the side frame 503. The second driver 506 is disposed on the first moving frame 104.

The second driver 506 is used to drive the first gear 505 to rotate so that the tooling platform 7 rotates in the X-Z plane to adjust the inclination angle of the steel member on the tooling platform in the X-Z plane.

[0064] It can be understood that the moving end of the X-axis moving mechanism 1 is the first moving frame 104, the moving end of the Y-axis moving mechanism 2 is the second moving frame 204, the moving end of the Z-axis moving mechanism 3 is the third moving frame, and the moving end of the first translation mechanism 8 is the fourth moving frame.

[0065] Further explanation, the structure and selection of the tooling for fixing the steel member and the laser cutting mechanism are common technical means for those skilled in the art, and will not be elaborated here. The driver can adopt methods such as motor drive, hydraulic drive mechanism, and pneumatic drive mechanism, and a speed reducer or coupling is provided at the output end of the driver according to needs, which is common technology for those skilled in the art and will not be elaborated here.

[0066] Example 2

[0067] The steel member laser cutting device of this embodiment is basically the same as that of Embodiment 1. The difference is that in order to conveniently adjust the horizontal angle and inclination angle of the laser cutting mechanism 6 to change the incident angle of the laser, a two-axis adjustment mechanism 9 is added to the first translation mechanism 8 in this embodiment, and the laser cutting mechanism 6 is arranged on the two-axis adjustment mechanism 9.

[0068] Specifically, as Figure 6 and Figure 10 shown, the two-axis adjustment mechanism 9 includes a first frame 901, a second frame 902, a third frame 903, an eighth driver 904 and a ninth driver 905. The first frame 901 is arranged on the fourth moving frame 806. The second frame 902 is rotatably arranged on the first frame 901. The eighth driver 904 is arranged on the first frame 901, and the output end is connected to the second frame 902. The eighth driver 904 is used to drive the second frame 902 to rotate in the horizontal plane (this horizontal plane refers to the X-Y plane when the first angle adjustment mechanism 4 is in the initial state. If the first angle adjustment mechanism 4 rotates, this horizontal plane will also rotate accordingly). The third frame 903 is rotatably arranged on the second frame 902. The ninth driver 905 is arranged on the second frame 902, and the output end is connected to the third frame 903. The ninth driver 905 is used to drive the third frame 903 to rotate in the vertical plane (this vertical plane refers to the Y-Z plane when the first angle adjustment mechanism 4 and the second frame 902 are in the initial state. If the first angle adjustment mechanism 4 rotates and the second frame 902 changes the angle, this vertical plane will also rotate accordingly). The laser cutting mechanism 6 is arranged on the third frame 903.

[0069] Example 3

[0070] The steel member laser cutting device of this embodiment is basically the same as that of Embodiment 1. The difference is that in order to keep the steel member at the corresponding angle after adjusting the inclination angle of the steel member in the X-Z plane, based on this, a locking mechanism 10 is added in this embodiment to keep the angle of the steel member (tooling platform 7).

[0071] As Figure 7 and Figure 11As shown, in this embodiment, the locking mechanism 10 includes a sleeve 1001, a guide rod 1002, a return spring 1003, a third driver 1004, a friction block 1005, a limiting piece 1006, a lever 1007, a connecting rod 1008 and a rotating seat 1009. Both the sleeve 1001 and the third driver 1004 are arranged on the first moving frame 104. The guide rod 1002 is arranged inside the sleeve 1001. A friction block 1005 is arranged at one end of the guide rod 1002 close to the side frame 503, and a limiting piece 1006 is arranged at the other end of the guide rod 1002 far from the side frame 503. The return spring 1003 is arranged on the guide rod 1002, and both ends of the return spring 1003 abut against the sleeve 1001 and the limiting piece 1006 respectively. The return spring 1003 is used to provide an elastic force that makes the guide rod 1002 move away from the side frame 503.

[0072] In this embodiment, the third driver 1004 drives the guide rod 1002 to move towards the side frame 503 through the connecting rod 1008 and the lever 1007, so that the friction block 1005 abuts against the side frame 503, thereby preventing the tooling platform 7 from rotating. The third driver 1004 can also directly drive the guide rod 1002 to move. Specifically, the rotating seat 1009 is arranged on the first moving frame 104. The middle part of the lever 1007 is rotatably connected to the rotating seat 1009. The first end of the lever 1007 is hinged to the first end of the connecting rod 1008, and the second end of the connecting rod 1008 is hinged to the output end of the third driver 1004. The third driver 1004 is used to drive the lever 1007 to rotate through the connecting rod 1008, so that the second end of the lever 1007 pushes the guide rod 1002 to move.

[0073] Furthermore, in order to improve the locking sensitivity, after locking the tooling platform 7, it is necessary to disconnect the drive of the second gear-rack drive mechanism 5b. For this reason, a second translation mechanism 11 is added. Specifically, the second translation mechanism 11 includes a fifth moving frame 1103, a fifth guide rail 1104 and a fifth slider 1105. The fifth guide rail 1104 is arranged on the first moving frame 104. The fifth moving frame 1103 is arranged on the fifth guide rail 1104 through the fifth slider 1105. Both the second driver 506 and the first gear 505 are arranged on the fifth moving frame 1103. The fifth moving frame 1103 is also provided with a guide frame 1101. A guide groove 1102 is formed on the guide frame 1101. The guide groove 1102 forms a certain angle with the moving direction of the fifth moving frame 1104, and the angle range is 10° to 80°. A guide block 1010 is arranged at the output end of the third driver 1004. The guide block 1010 cooperates with the guide groove 1102, and the guide block 1010 can slide relatively along the guide groove 1102. When the third driver 1004 pushes the guide rod 1002 to move towards the side frame 503, it can push the fifth moving frame 1103 to move along the fifth guide rail 1104 through the guide frame 1101, so that the first gear 505 moves away from the arc-shaped rack 504.

[0074] It is understandable that the mobile end of the second translation mechanism 11 is the fifth moving frame.

[0075] In this embodiment, the guide frame 1101 straddles the sleeve 1001. To increase the translation accuracy of the guide frame 1101, a cage 1106 is provided on the sleeve 1001.
