[0034] In detail, a linear slide rod is fixedly connected to the inner side of the adjusting seat 3, and the guide frame 6 is also slidably connected to the outer side of the linear slide rod. By using the linear slide rod, the displacement of the guide frame 6 can be effectively guided, and uncontrollable movement of the guide frame 6 can be avoided.

[0035] The steel component mounting assembly 7 includes a support shaft 8, a mounting plate 9, a linear guide rail 10, a positioning plate 11, a linkage rod 12, and a displacement plate 13. The top of the guide frame 6 is rotatably connected to the support shaft 8, which is a hollow structure. One end of the support shaft 8 is fixedly connected to the mounting plate 9. Both ends of the mounting plate 9 are fixedly connected to the linear guide rail 10. The top and bottom ends of the linear guide rail 10 are slidably connected to the positioning plate 11. The two positioning plates 11 are rotatably connected to the side that is far apart from each other. The displacement plate 13 is provided inside the support shaft 8.

[0036] Furthermore, a limiting groove is provided on the side of the positioning plate 11 near the linear guide rail 10.

The linkage rod 12 is connected to the mounting ear through a rotating shaft. By using the mounting ear, the linkage rod 12 can be stably assembled with the positioning plate 11 and can rotate around the rotating shaft as a fulcrum.

[0038] Example 2

[0039] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a steel component mounting assembly 7;

[0040] In this embodiment, the steel component mounting assembly 7 further comprises linkage plates 14, transmission spur gears 15, extension frames 16, drive motors 17 and reduction spur gears 18, the top end and the bottom end of the displacement sheet 13 are fixedly connected with the linkage plates 14, and the ends of the two linkage rods 12 away from the positioning plate 11 are rotatably connected with the ends of the two linkage plates 14, the outer side of the other end of the support shaft 8 is fixedly connected with the transmission spur gear 15, one side of the top of the guide frame 6 is fixedly connected with the extension frame 16, one side of the extension frame 16 is fixedly connected with the drive motor 17, the output end of the drive motor 17 is fixedly connected with the reduction spur gear 18, and the reduction spur gear 18 is meshingly connected with the transmission spur gear 15, and the bottom end of the extension frame 16 is fixedly connected with the hydraulic cylinder 19, and the output end of the hydraulic cylinder 19 is rotatably connected with the middle part of the displacement sheet 13.

[0041] In detail, the top end and the bottom end of the support shaft 8 are provided with avoiding through grooves, and the linkage plates 14 extend to the outer side of the support shaft 8 through the avoiding through grooves. By the arrangement of the avoiding through grooves, when the displacement sheet 13 is displaced, the displacement of the linkage plates 14 can be avoided.

[0042] In detail, the diameter of the reduction spur gear 18 is smaller than the diameter of the transmission spur gear 15. By the diameter change of the reduction spur gear 18 and the transmission spur gear 15, the transmission ratio between the transmission spur gear 15 and the reduction spur gear 18 can be effectively reduced, and the rotation speed of the support shaft 8 is effectively controlled.

[0043] A specific application of the above two embodiments is that first, the transmission motor 5 is started to drive the transmission screw 4 to rotate, and the transmission screw 4 is connected with the guide frame 6, so that the guide frame 6 can be displaced along the transmission screw 4, thereby adjusting the distance between the two guide frames 6. Then, the steel component is placed between the two mounting plates 9, and then the hydraulic cylinder 19 is started to push the displacement sheet 13 to displace. In the sliding process of the displacement sheet 13, the linkage plate 14 can push the linkage rod 12 through the connection between the displacement sheet 13 and the linkage plate 14. Since the linkage rod 12 is connected between the linkage plate 14 and the positioning plate 11, the positioning plate 11 can be pushed through the linkage rod 12, so that the positioning plate 11 is close to each other, and the effective positioning of the steel component is formed.

[0044] Then, the bevel of the steel component is cut by the bearing table 1, and the transmission motor 5 can be started to drive the transmission screw 4 to rotate. Since the plate material is limited between the two guide frames 6, when the guide frame 6 is displaced, the contact position of the steel component with the working end of the plasma cutting machine body 2 can be adjusted. The drive motor 17 can be started to drive the reduction spur gear 18 to drive the transmission spur gear 15, and the transmission spur gear 15 is connected with the support shaft 8, so that the support shaft 8 can drive the mounting plate 9 to rotate, thereby driving the steel component to overturn, and realizing the cutting operation at different positions of the steel component.

[0045] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
