DETAILED DESCRIPTION

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0055] like Figure 1 - Figure 13As shown, an embodiment of the present invention provides a sheet metal laser cutting device with a steering function, which is used for cutting thin sheet metal of medium and large sizes, and is mainly used for cutting the edge contour of the sheet metal. It includes: a laser cutting component 1 and a steering support component 2. The laser cutting component 1 has a horizontal U-shaped opening, so that the side of the sheet metal 3 can be inserted from one side of the horizontal U-shaped opening to the bottom of the laser cutting head 1015. The laser cutting head 1015 of the laser cutting component 1 is arranged along the length direction of the horizontal U-shaped opening. A group of linear moving structures can be used to drive the position of the laser cutting head 1015 to achieve the adjustment of the position of the laser cutting head 1015 and the control of the cutting position of the sheet metal 3. The steering support component 2 is fixedly installed on the side of the laser cutting component 1, and the laser cutting component 1 is close to the opening side of the horizontal U-shaped opening. The steering support component 2 is used to manipulate the rotation and linear movement of the sheet metal 3.

[0056] When performing laser cutting on the sheet metal 3, the sheet metal 3 is placed (or installed) on the steering support assembly 2, and then the steering support assembly 2 is used to manipulate one side edge of the sheet metal 3 to insert into the inner side of the horizontal U-shaped opening, and then the position of the laser cutting assembly 1 is adjusted to meet the requirements of the cutting shape / size. Then the laser cutting head 1015 works, and the steering support assembly 2 manipulates the sheet metal 3 to move perpendicular to the direction of the horizontal U-shaped opening to achieve the removal of one side contour of the sheet metal 3. After that, the steering support assembly 2 manipulates the sheet metal 3 to rotate 180°, and then controls the sheet metal 3 to move perpendicular to the direction of the horizontal U-shaped opening to achieve laser cutting of the contours on both sides of the sheet metal 3.

[0057] In this embodiment, a laser cutting assembly 1 is designed, which has a horizontal U-shaped opening. The laser cutting head 1015 of the laser cutting assembly 1 is arranged along the length direction of the horizontal U-shaped opening. This structure only designs a set of linear moving structures, so that the overall structure of the laser cutting assembly 1 is simple and the cost is low. In conjunction with the steering support assembly 2 that can control the rotation and linear movement of the sheet metal part 3, it can realize the cutting of the side contours of medium and large-sized thin sheet metals, meet the needs of small and medium-sized enterprises for low-cost cutting of large-sized sheet metals, and improve the economic benefits of the enterprises.

[0058] In one embodiment, the steering support assembly 2 includes: a transverse support system, a rotating member 206, a V-shaped frame 208, and a support plate 2011; wherein, one end of the transverse support system is installed on the side of the laser cutting assembly 1, and the rotating member 206 is installed on the end of the transverse support system away from the laser cutting assembly 1. The corner of the V-shaped frame 208 is rotatably installed with the rotating member 206, and a limiting member 208a is provided at the bottom of the V-shaped frame 208, and a limiting block 206a is provided on the side of the rotating member 206. The limiting block 206a cooperates with the limiting member 208a so that the symmetry plane of the V-shaped frame 208 is perpendicular to the length direction of the U-shaped opening, as shown in FIG. Figure 12As shown in the figure, the limit block 206a is a rectangular parallelepiped, the limit member 208a is annular, and a semi-arc-shaped protruding part is provided on the side, and the semi-arc-shaped protruding part corresponds to the rectangular parallelepiped. In this structure, when the symmetry plane of the V-shaped frame 208 is perpendicular to the length direction of the U-shaped mouth, the end of the semi-arc-shaped protruding part is against the side of the rectangular parallelepiped, and after the V-shaped frame 208 is rotated 180°, the other end of the semi-arc-shaped protruding part is against the side of the rectangular parallelepiped, so that the user can conveniently manipulate the V-shaped frame 208 to rotate so that the symmetry plane of the V-shaped frame 208 is perpendicular to the length direction of the U-shaped mouth. The bottom of the support plate 2011 is fixedly connected to the first rail 2011a and two second rails 2011b. The first rail 2011a slides with the corner of the V-shaped frame 208, and the two second rails 2011b slide with the two ends of the V-shaped frame 208 respectively.

[0059] When using, such as Figure 3 In the middle state, the length direction of the support plate 2011 of the steering support assembly 2 is perpendicular to the length direction of the U-shaped opening. At this time, the linear drive support plate 2011 can be manipulated to slide linearly along its length direction. When one end of the linear drive support plate 2011 (generally, one end of the linear drive support plate 2011 is set to a circular arc end) approaches the rotating part 206, the linear drive support plate 2011 can be manipulated to rotate 180° around the central axis of the rotating part 206. At this time, the length direction of the support plate 2011 of the steering support assembly 2 is also perpendicular to the length direction of the U-shaped opening. The linear drive support plate 2011 is manipulated to slide linearly along its length direction again. In the above-mentioned process of manipulating the movement of the linear drive support plate 2011, the sheet metal part 3 set on the linear drive support plate 2011 is synchronously carried to move, and the side contour of the sheet metal part 3 is cut in cooperation with the laser cutting head 1015.

[0060] In one embodiment, the length of the transverse support system can determine the maximum width of the sheet metal part 3 that can actually be cut by the sheet metal laser cutting device with a steering function.

By adjusting the angle of the first connecting rod 202 and the second connecting rod 203, the distance between the rotating member 206 and the connecting seat 201 can be adjusted. The second telescopic member 204 is arranged horizontally, and the length direction of the second telescopic member 204 is consistent with the length direction of the U-shaped opening. One end of the second telescopic member 204 is fixedly connected to the connecting seat 201, and the telescopic end of the second telescopic member 204 is fixedly installed on the rotating member 206. The second telescopic member 204 is used to limit the rotating member 206 so that the rotating member 206 can only move along the telescopic length direction of the second telescopic member 204. One end of the transverse reinforcement seat 205 is fixedly connected to the connecting seat 201, and the second telescopic member 204 is located on the inner side of the transverse reinforcement seat 205. The transverse reinforcement seat 205 is used to improve the structural strength of the second telescopic member 204 to avoid deformation of the second telescopic member 204.

[0061] In one embodiment, in order to further improve the structural strength of the transverse support system, an auxiliary stabilizing frame 207 is also designed.
