[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

[0032] See also Figure 4 and Figure 5 The support mechanism 3 includes a fixed seat 31, and two fixed seats 31 are symmetrically fixedly sleeved on the horizontal section of the U-shaped rod 2. The upper ends of the two fixed seats 31 are fixedly connected with short rods 32, and the upper ends of the short rods 32 are rotatably connected with U-shaped supports 33. The rear end surfaces of the U-shaped supports 33 are fixedly connected with straight plates 34, and the distance between the two straight plates 34 gradually increases from front to back. Two waist-shaped through grooves 35 extending in the left and right directions are symmetrically opened on the table plate 12, and the two waist-shaped through grooves 35 are commonly connected with an angle adjustment mechanism 4 that cooperates with the support mechanism 3.

[0033] See also Figure 4 and Figure 5The angle adjustment mechanism 4 includes a slide 41, and two slides 41 are provided. The two slides 41 are symmetrically slidably connected in the two waist-shaped through grooves 35. The upper ends of the slides 41 are fixedly connected with limit rods 42 extending in the up-down direction. The upper end surfaces of the two straight plates 34 are provided with slide grooves 43 running through the upper and lower ends. A connecting seat 44 is slidably sleeved on the straight plate 34. The connecting seat 44 is fixedly connected to the upper end of the limit rod 42. The lower ends of the two slides 41 are commonly connected with a bidirectional moving component 45. The rear end of the support mechanism 3 is connected with a pushing mechanism 5, and the front side of the operating table 1 is connected with a processing mechanism 6.

[0034] In the specific operation, first, the relative positions of the two slides 41 in the waist-shaped slide groove 43 are adjusted by the bidirectional moving component 45, and then the angle between the two U-shaped supports 33 is adjusted to determine the cutting path of the workpiece, and then the two workpieces to be processed are symmetrically placed on the two U-shaped supports 33 (such as Figure 3 As shown in the figure, the workpieces are clamped by the pushing mechanism 5 and pushed forward synchronously. The front and rear ends of the two workpieces are also aligned during the pushing process. After the workpieces move to the specified position, the pushing mechanism 5 stops pushing. At this time, the two workpieces are cut along the cutting path in sequence by the processing mechanism 6. After the cutting is completed, the pushing mechanism 5 continues to push the workpiece forward so that the cuts of the two workpieces fit together. Finally, the two workpieces are welded together along the welding path by the processing mechanism 6.

[0035] See also Figure 4 and Figure 5 The bidirectional moving component 45 includes a threaded seat 451, which is fixedly connected to the table 12 at a position in the middle between the two waist-shaped through grooves 35. An adjusting rod 452 is threadedly connected to the threaded seat 451, and a rotating seat 453 is fixedly connected to the top of the adjusting rod 452. A bidirectional module 454 is connected to the lower end of the threaded seat 451, and a limiting module 455 is commonly connected to the adjusting rod 452 and the bidirectional module 454.

The lower ends of the two sliding seats 41 are fixedly connected with L-shaped toothed plates 4543, and the two L-shaped toothed plates 4543 are symmetrical with the axis of the linkage gear 4542 as the symmetry axis. The horizontal sections of the two L-shaped toothed plates 4543 in the left and right directions are located on the front and rear sides of the linkage gear 4542 and are both engaged with the linkage gear 4542.

[0037] See also Figure 6The limiting module 455 includes a limiting groove 4551, and two limiting grooves 4551 are provided. The two limiting grooves 4551 extend in the up-down direction and are symmetrically opened on the side wall of the adjusting rod 452. A fixing block 4552 is slidably connected in the limiting groove 4551, and the two fixing blocks 4552 are fixedly connected to the inner wall of the linkage gear 4542.

[0038] During specific work, when it is necessary to adjust the angle between the two U-shaped supports 33, and then adjust the angle between the two workpieces after splicing, it is necessary to rotate the rotating seat 453 to drive the adjusting rod 452 to rotate synchronously. At this time, under the action of the fixed block 4552 and the limiting groove 4551, the linkage gear 4542 also rotates synchronously, driving the two L-shaped tooth plates 4543 to approach or move away, and then the two slides 41 and the limiting rod 42 also approach or move away synchronously. While moving, the limiting rod 42 will drive the straight plate 34 to rotate around the axis of the short rod 32, and then the two U-shaped supports 33 also rotate synchronously driven by the straight plate 34.

[0039] See also Figure 3 and Figure 4 The pushing mechanism 5 includes a connecting seat 51, which is fixedly connected to the rear position of the table 12. A No. 1 cylinder 52 is fixedly connected to the connecting seat 51. The piston rod of the No. 1 cylinder 52 is forward and fixedly connected to a linkage plate 53 through a spring rod. The left and right ends of the linkage plate 53 are symmetrically fixedly connected to limit plates. Two traction assemblies 54 are symmetrically connected to the linkage plate 53. The rear ends of the two traction assemblies 54 are connected to the rear ends of the two straight plates 34.

[0040] See also Figure 3 and Figure 4 The traction assembly 54 includes a sleeve 541, which is slidably mounted on the linkage plate 53. The upper end of the sleeve 541 is fixedly connected to a vertical plate 542, and the front end of the vertical plate 542 is fixedly connected to a straight rod 543. The front end of the straight rod 543 is connected to a rectangular seat 544 through a ball joint, and the front end of the rectangular seat 544 is connected to a clamping module 545.

[0041] See also Figure 3 and Figure 4 The clamping module 545 includes a bearing tube 5451, the front end of which is slidably sleeved on the rear end of the straight plate 34, the rear end of the bearing tube 5451 is fixedly connected to the rectangular seat 544, and a rectangular plate 5452 for clamping the workpiece is fixedly connected to the upper position of the front end surface of the rectangular seat 544.

[0042] During specific operation, in the initial state, the piston rod of the No. 1 cylinder 52 is in a retracted state, the connecting plate 53 is in a rear position on the table 12, and the spring rod is in a natural state. In the process of adjusting the angle between the two U-shaped supports 33, the bearing tube 5451 can slide relative to the straight plate 34 to offset the displacement in the front and rear directions caused by the rotation of the straight plate 34. At the same time, the sleeve 541 also slides relative to the connecting plate 53 driven by the rectangular seat 544 and the straight rod 543, so as to perform adaptive adjustment according to the rotation of the bearing tube 5451.

[0043] After the angle adjustment is completed, the two workpieces are placed symmetrically on the U-shaped support 33 and the supporting tube 5451, and the connecting plate 53 is pushed forward by the No. 1 cylinder 52, and the rectangular seat 544 is driven forward by the sleeve 541, the vertical plate 542 and the straight rod 543, and then the supporting tube 5451 will slide forward relative to the straight plate 34, so that the horizontal end below the workpiece is inserted into the gap between the rectangular plate 5452 and the rectangular seat 544, so as to limit the workpiece in the up and down directions, and the U-shaped support 33 will limit the workpiece in the left and right directions. In this way, the workpiece is clamped. After clamping is completed, as the connecting plate 53 continues to move forward driven by the No. 1 cylinder 52, the workpiece can be pushed forward to the specified position. At this time, since the rear end of the workpiece is abutted against the rectangular seat 544, the front end of the workpiece is also aligned.

[0044] See also Figure 3 and Figure 7 The processing mechanism 6 includes a mounting plate 61, which is fixedly connected between the vertical sections on the front sides of the two H-shaped legs 11. Two telescopic rods 62 are fixedly connected to the mounting plate 61 symmetrically. A avoidance component 63 is commonly connected between the movable sections of the two telescopic rods 62. The front ends of the movable sections of the telescopic rods 62 are commonly connected to a connecting frame 64. A No. 1 electric slider 65 that can move left and right is slidably provided on the horizontal section of the connecting frame 64. The No. 1 electric slider 65 is fixedly connected to two brackets 66 symmetrically on the left and right. The upper ends of the two brackets 66 are commonly connected to a cutting and welding component 67.

[0045] See also Figure 7 The avoidance component 63 includes a cross bar 631, which is fixedly connected between the movable sections of the two telescopic rods 62. A limit block 632 is slidably sleeved on the cross bar 631. The front end face of the limit block 632 is fixedly connected to the No. 1 electric slider 65 through a connecting rod 633, so as to prevent the No. 1 electric slider 65 from rotating on the connecting frame 64. The rear end face of the mounting plate 61 is symmetrically fixedly connected to two No. 2 cylinders 634. The piston rods of the two No. 2 cylinders 634 pass through the mounting plate 61 and are fixedly connected to the cross bar 631.

[0046] See also Figure 7 and Figure 8The cutting and welding assembly 67 includes a U-shaped track 671, and the upper ends of the two brackets 66 are fixedly connected with the U-shaped track 671. The U-shaped track 671 opens backward, and the outer wall of the U-shaped track 671 is provided with a U-shaped groove 672 from the outside to the inside. A spherical mounting seat 673 is slidably connected in the U-shaped groove 672, and the upper end of the spherical mounting seat 673 is fixedly connected with a No. 2 electric slider 674. A small laser cutting and welding machine 675 is fixedly connected to the No. 2 electric slider 674 and the spherical mounting seat 673.

[0047] During specific operation, after the workpiece reaches the designated position and stops moving, the spherical mounting seat 673 is located in the horizontal section below the U-shaped track 671, and the laser cutting head of the small laser cutting and welding machine 675 is upward, and the bracket 66 and the U-shaped track 671 are driven by the No. 1 electric slide to move to align with one of the workpieces, and the top of the small laser cutting and welding machine 675 is aligned with the starting point of the cutting path of the workpiece (such as Figure 2 Then, the second electric slider 674 drives the spherical mounting seat 673 and the small laser cutting and welding machine 675 to move along the U-shaped track 671, and then the workpiece can be cut by the small laser cutting and welding machine 675. When the small laser cutting and welding machine 675 moves along the cutting path to the cutting end point (as shown in point a in the figure), the workpiece is cut by the small laser cutting and welding machine 675. Figure 2 After that, the cutting of a single workpiece is completed, and the excess scraps cut off fall off under the action of their own gravity.

[0048] Afterwards, the No. 1 electric slider 65 drives the bracket 66 and the U-shaped track 671 to move to align with another workpiece, and the workpiece is cut in the same way as the above method. After cutting is completed, the No. 1 cylinder 52 pushes the two workpieces to continue moving forward, so that the cross sections of the two workpieces will fit together. In this process, since the two workpieces move forward a certain distance, the two No. 2 cylinders 634 also need to synchronously push the cross bar 631 forward the same distance. At the same time, the movable section of the telescopic rod 62 extends forward the same distance. Then, the small laser cutting and welding machine 675 is switched to welding mode, and the No. 1 electric slider 65 is slid to the joint of the two workpieces, and the No. 2 electric slider 674 drives the spherical mounting seat 673 and the small laser cutting and welding machine 675 to move along the U-shaped groove 672, and the small laser cutting and welding machine 675 is used to weld the joint of the workpieces.
