[0041] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0042] like Figure 1-Figure 9 As shown, a laser arc hybrid welding device comprises a base 1, and the base 1 is provided with a displacement device and a movable bracket 2, and the bracket 2 is provided with a movable slider 3.

[0043] At the same time, the slider 3 is provided with a rotatable rotating plate 31 on one side close to the displacement device, and the rotating plate 31 is provided with an arc groove 1 311 and an arc groove 2 312, wherein the arc groove 1 311 has a gear 1 32 built in, and the gear 1 32 is meshed with the inner wall of the arc groove 1 311, and the arc groove 2 312 has a gear 2 33 and a gear 3 34 built in, and the two sides of the gear 2 33 are respectively meshed with the inner wall of the arc groove 1 311 and the gear 3 34.

[0044] The meshing refers to the fact that a plurality of teeth are arranged on the inner wall of the arc-shaped groove to form an internal gear.

[0045] Moreover, gear one 32 is connected to a laser welding head, and gear three 34 is connected to an arc welding head. Therefore, in actual use, by rotating the rotating plate 31, gear one 32 and gear three 34 are driven to rotate and the laser welding head and the arc welding head are rotated to adjust the angle between the laser welding head and the arc welding head, thereby expanding the welding range. In addition, by adapting the displacement device, the welding range can be further expanded.

[0046] At the same time, the positioner and the welding head are located on the same device, so one device can be purchased directly without adjusting the position, which is more convenient.

[0047] Among them, gear one 32, gear two 33 and gear three 34 are all sleeved on the shaft, and bearings are arranged between the shaft, and gear one 32 and the laser welding head rotate synchronously, and gear three 34 and the arc welding head rotate synchronously.

[0048] Moreover, the slider 3 is provided with at least two installation positions corresponding to the gear 1 32 , or / and, the slider 3 is provided with at least two installation positions corresponding to the gear 2 33 and the gear 3 34 .

[0049] Therefore, in actual use, different positions can be adjusted, thereby further expanding the welding range.

[0050] At the same time, a driving source 4 is provided on the slider 3, and a driving shaft 41 of the driving source 4 is provided with a gear four 42, and the rotating plate 31 is connected with a gear five 35, and a gear six 36 is provided between the gear four 42 and the gear five 35, and the slider 3 is provided with a mounting shaft 361 on the side close to the displacement device, and the rotating plate 31 is provided with an arc groove three 313.

[0051] The driving source 4 is a motor, so in actual use, the speed can be further reduced due to the setting of the gear six 36, and one end of the mounting shaft 361 passes through the gear six 36 and is located in the arc groove three 313, and a bearing 37 is provided between the gear six 36 and the mounting shaft 361, so that the rotating plate 31 can be limited and guided for rotation.

[0052] The gear six 36 is also sleeved on the shaft, and a bearing is arranged between the gear and the shaft, and the gear five 35 is connected to the rotating plate 31 through a rotating shaft, and the gear five 35, the rotating plate 31 and the rotating shaft rotate synchronously.

[0053] like Figure 4 As shown, the gear 32 is connected to an elastic clamping member 5, and the clamping member 5 is provided with a through hole 51, and one side of the through hole 51 is open, and a positioning bead 52 is provided on the inner wall of the through hole 51, and a positioning groove 1 is provided at the laser welding head corresponding to the positioning bead 52.

[0054] Similarly, the gear three 34 is connected with an elastic clamping member 5, and the clamping member 5 is provided with a through hole 51, and one side of the through hole 51 is open, and a positioning bead 52 is provided on the inner wall of the through hole 51, and a positioning groove 1 is provided at the arc welding joint corresponding to the positioning bead 52.

[0055] Therefore, in actual use, the laser welding head and / or the arc welding head enters into the through hole 51 from the opening and is clamped. This is because the elasticity of the clamping member 5 allows the opening to open outward and reset after opening. At the same time, the laser welding head and / or the arc welding head is limited by the adaptation of the positioning bead 1 52 and the positioning groove 1.

[0056] The positioning bead 52 is a structure composed of a shell, a spring and a ball, and the ball cooperates with the spring to achieve telescopic movement.

[0057] like Figure 5-Figure 9 As shown, the structure of the displacement device, first of all, the displacement device includes a mounting seat 6, and a rotatable rotating table 7 is arranged on the mounting seat 6, and the rotating table 7 is provided with a rotatable rotating disk 8, and the rotating disk 8 is provided with a clamping assembly 9, and the clamping assembly 9 and the rotating disk 8 are plugged in.

[0058] At the same time, the clamping assembly 9 includes a fixed block 91 and a movable moving block 92, and a spring 1 is arranged between the fixed block 91 and the moving block 92. By moving the moving block 92 outward, the workpiece is positioned between the fixed block 91 and the moving block 92, and no force is applied to the moving block 92. The moving block 92 moves inward under the elasticity of the spring 1 to clamp the workpiece.

[0059] Therefore, in actual use, the workpiece is clamped by setting the fixed block 91 and the movable block 92 in cooperation with the spring 1. Compared with the prior art, the present invention has low cost, simple structure and convenient operation.

[0060] The specific structure of simultaneous plug-in is: first, the clamping assembly 9 also includes a connecting seat 93, and a fixed block 91 and a movable moving block 92 are arranged on the connecting seat 93, and a connecting block 931 is arranged at the bottom of the connecting seat 93, and the rotating disk 8 is provided with an installation groove 81, and a positioning bead 2 82 is arranged on the inner wall of the installation groove 81, and the connecting block 931 is located in the installation groove 81 and a positioning groove 932 is arranged corresponding to the positioning bead 2 82.

[0061] Therefore, in actual use, the positioning bead 82 is located in the positioning groove 932 to achieve installation and limiting, and force is applied to separate the positioning bead 82 and the positioning groove 932 for disassembly, wherein the positioning bead 82 is a structure composed of a shell, a spring and a ball, and the ball cooperates with the spring to achieve extension and retraction.

[0062] like Figure 5-Figure 9As shown, the limiting structure of the moving block 92 is: first, a movable limiting block 94 is provided on one side of the moving block 92 of the connecting seat 93, and a second spring is provided between the limiting block 94 and the connecting seat 93, and the limiting block 94 abuts against the outer side of the moving block 92 to limit the movement of the moving block 92.

[0063] Therefore, in actual use, the limit block 94 abuts against the outer side of the movable block 92 to limit the movement of the movable block 92. When the movable block 92 moves outward, the limit block 94 moves downward due to the force applied to it, and when the limit block 94 is subjected to force again, it moves upward under the action of spring 2.

[0064] Secondly, the moving structure of the moving block 92 is as follows: first, a convex strip 95 is provided on the connecting seat 93, and a groove 921 is provided on the moving block 92 corresponding to the convex strip 95, and the moving block 92 moves along the convex strip 95. At the same time, a convex strip 951 is provided at one end of the convex strip 95 close to the fixed block 91, and a slot 922 is provided on the moving block 92 corresponding to the convex strip 951.

[0065] Therefore, in actual use, the moving block 92 moves along the convex strip 95 and is limited by the adaptation of the convex block 951 to the slot 72.

[0066] like Figure 5-Figure 9 As shown, the rotating platform 7 is L-shaped and includes a horizontal plate 71 and a vertical plate 72 , and a rotatable rotating disk 8 is arranged on the horizontal plate 71 , and a display screen 73 is arranged on the vertical plate 72 .

[0067] The rotation of the rotating table 7 and the rotating disk 8 is driven by a motor. The specific structure is that a rotating shaft connects the rotating table 7 and the mounting base 6, and a motor drives the rotating shaft to drive the rotating table 7. Similarly, a rotating shaft connects the rotating table 7 and the rotating disk 8, and a motor drives the rotating shaft to drive the rotating disk 8. In addition, the display screen 73 can be set to touch screen operation for easy operation.

[0068] like Figure 1-Figure 2 As shown, the bracket 2 includes a cross bar 21 and two mounting bars, wherein the mounting bars are movably arranged on the base 1, and the cross bar 21 is located between the two mounting bars, and a movable slider 3 is arranged on the cross bar 21. At the same time, the mounting bars include an upper bar 22 and a lower bar 23, and the bottom of the upper bar 22 is located in the lower bar 23 and moves in the lower bar 23.

[0069] Therefore, in actual use, the movement of the mounting rod, the upper rod 22 and the slider 3 is realized in three directions. And the slider 3 is L-shaped, i.e., connected on both sides, so that the movement is more stable.

[0070] The above shows and describes the basic principle and main features of the present invention and the advantages of the present invention. At the same time, the present invention is not limited by the above embodiments, so without departing from the principle and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
