DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention. Embodiment 1:

[0020] like Figure 1 - Fig.13 As shown, an embodiment of the present invention provides a sheet metal laser cutting device with a steering function, which is used for cutting medium and large-sized thin sheet metals, 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 adjustable position of the laser cutting head 1015 and control 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.

[0021] When the sheet metal part 3 is laser cut, the sheet metal part 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 part 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, and then the laser cutting head 1015 works, and the steering support assembly 2 manipulates the sheet metal part 3 to move perpendicular to the horizontal U-shaped opening to achieve the removal of one side contour of the sheet metal part 3, and then the steering support assembly 2 manipulates the sheet metal part 3 to rotate 180°, and then controls the sheet metal part 3 to move perpendicular to the horizontal U-shaped opening to achieve laser cutting of the contours on both sides of the sheet metal part 3.

[0022] In this embodiment, a laser cutting component 1 is designed, which has a horizontal U-shaped opening. The laser cutting head 1015 of the laser cutting component 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 component 1 is simple and the cost is low. In conjunction with the steering support component 2 that can control the rotation and linear movement of the sheet metal part 3, it can achieve the cutting of the side contour 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.

[0023] 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, and the V-shaped frame 208 is rotatably installed with the rotating member 206 at the corner, 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, and 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 mouth, such as Fig.12 As shown in , the limit block 206a is a rectangular parallelepiped, the limit member 208a is annular, and a semi-arc-shaped protruding part is arranged 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 abuts against the side of the rectangular parallelepiped, and after the V-shaped frame 208 rotates 180°, the other end of the semi-arc-shaped protruding part abuts against the side of the rectangular parallelepiped, so that the user can conveniently operate 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 with a first track 2011a and two second tracks 2011b. The first track 2011a slides with the corner of the V-shaped frame 208, and the two second tracks 2011b slide with the two ends of the V-shaped frame 208 respectively.

[0024] When using, 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 as an arc-shaped end) approaches the rotating member 206, the linear drive support plate 2011 can be manipulated to rotate 180° around the central axis of the rotating member 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.

The second telescopic member 204 is horizontally arranged, 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 rotating member 206 is limited by the second telescopic member 204, 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.
