DETAILED DESCRIPTION

[0026] Example 1

[0027] The laser welding torch adjustment mechanism in this embodiment includes a laser output end 1, an arc heat source melting electrode welding torch 2, a two-dimensional adjustment component 3 and an angle adjustment component 4.

The laser output end 1 is connected to the two-dimensional adjustment component 3, and the arc heat source melting electrode welding torch 2 is connected to the angle adjustment component 4. The two-dimensional adjustment component 3 drives the laser output end 1 to move relative to the arc heat source melting electrode welding torch 2, and the angle adjustment component 4 drives the arc heat source melting electrode welding torch 2 to swing relative to the laser output end 1. In some other embodiments, such as Figure 2 As shown, the installation positions of the two-dimensional adjustment component 3 and the angle adjustment component 4 can also be interchanged, and can also meet the same adjustment requirements. By setting the two-dimensional adjustment component 3, the relative position of the laser output end 1 relative to the welding wire can be quickly adjusted. By setting the angle adjustment component 4, the angle between the arc heat source melting electrode welding torch 2 and the laser output end 1 can be quickly adjusted to meet the requirements of different welding positions.

A connecting hole 305 is provided on the side wall of the mounting cavity 303. One end of the first adjustment screw 306 penetrates into the mounting cavity 303 and is inserted into the connecting hole 305. A first retaining spring is installed on the first adjustment screw 306. A first drive block 307 is mounted within the mounting cavity 303, and a first sliding pair 304 is mounted on the sidewall of the first drive block 307. The other side of the first sliding pair 304 is connected to the sidewall of the mounting cavity 303. A first adjustment screw 306 passes through the first drive block 307 and is threadedly engaged with the first drive block 307. A sliding plate 308 is slidably engaged with the bottom of the top plate 302. The bottom of the first drive block 307 passes through the top plate 302 and is fixedly connected to the top of the sliding plate 308. The front-to-back adjustment assembly is used for adjustment along the direction of the laser beam.

[0029] like Figure 8 As shown, the two-dimensional adjustment component 3 also includes an up-and-down adjustment assembly, which includes a fixed frame 309, a second sliding pair 310, a second adjustment screw 311, and a second drive block 312. The fixed frame 309 is fixedly connected to the bottom of the sliding plate 308. The second adjustment screw 311 penetrates the fixed frame 309 from the bottom. The second adjustment screw 311 is installed with a second retaining spring, which fits the inner bottom wall of the fixed frame 309. The second drive block 312 is installed on one side of the fixed frame 309. The second sliding pair 310 is installed on the side wall of the second drive block 312. The other side of the second sliding pair 310 is connected to the fixed frame 309. The second adjustment screw 311 passes through the second drive block 312 and is threadedly connected to the second drive block 312. Up-and-down adjustment refers to upward or downward adjustment in the direction perpendicular to the laser beam.

[0030] like Figure 6 、 Figure 7 As shown, a first long groove 313 is opened on the top plate 302 along its length direction, a first locking screw 314 is inserted into the first long groove 313, and the other end of the first locking screw 314 is threadedly connected to the top of the sliding plate 308; a second long groove 315 is opened on the side wall of the fixing frame 309 along its height direction, a second locking screw 316 is inserted into the second long groove 315, and the other end of the second locking screw 316 is threadedly connected to the side wall of the second driving block 312.

[0031] like Figure 9As shown, the angle adjustment component 4 also includes a support plate 401, a fixed seat 403 and a slider 404.

[0032] The two-dimensional adjustment component 3 and the angle adjustment component 4 can be mounted on different racks for fixation, or they can be connected to each other for fixation, such as Figure 1 As shown, the arc heat source melting electrode welding torch 2 is installed in the fixed seat 403 through the pressure plate 405, the laser output end 1 is installed in the fixed frame 309 and is fixedly connected to the second driving block 312, and the support plate 401 is installed on the fixed plate 301 or the top plate 302. When the support plate 401 is installed on the top plate 302, it moves synchronously with the top plate 302. When the support plate 401 is fixed on the plate 301, the top plate 302 will not drive the support plate 401 to move synchronously when it moves left and right.

[0033] Working principle: When adjusting forward and backward, Figure 6 As shown, the first adjusting screw 306 is rotated. The first adjusting screw 306 is restricted by the retaining spring and can only rotate in the mounting cavity 303. Under the cooperation of the threads, the first driving block 307 moves forward or backward, driving the sliding plate 308 to move, and the fixing frame 309 and the laser output end 1 to move forward and backward;

[0034] When making left and right adjustments, Figure 6 As shown, the third adjusting screw 314 is rotated. The end of the third adjusting screw 314 can only rotate within the top plate 302 and cannot move axially. The fixed plate 301 and the third adjusting screw 314 are threadedly engaged to achieve the purpose of driving the top plate 302 to move left or right.

[0035] When you need to adjust up or down, Figure 8 As shown, the second adjusting screw 311 is rotated to drive the second driving block 312 to move upward or downward, thereby achieving the purpose of driving the laser output end 1 to move;

[0036] When it is necessary to adjust the relative angle between the laser output end 1 and the arc heat source melting electrode welding torch 2, push the fixed seat 403 to make the slider 404 move along the arc-shaped slide groove 402 to achieve the purpose of adjusting the angle of the arc heat source melting electrode welding torch 2. The slider 404 is tightly fitted in the arc-shaped slide groove 402 to ensure that the slider 404 is stable in the arc-shaped slide groove 402.

[0038] The laser welding torch adjustment mechanism in this embodiment is as follows: Figure 3 As shown, the difference from Example 1 is that a two-dimensional adjustment component 3 is installed on both the laser output end head 1 and the arc heat source consumable electrode welding torch 2, and an angle adjustment component 4 is installed on the two-dimensional adjustment component 3 on the laser output end head 1, which can provide more diverse position adjustment needs and meet refined adjustment. In other embodiments, the angle adjustment component 4 can also be installed on the two-dimensional adjustment component 3 on the arc heat source consumable electrode welding torch 2. In other embodiments, the angle adjustment component 4 can also be installed on both the laser output end head 1 and the arc heat source consumable electrode welding torch 2, and the two-dimensional adjustment component 3 can be installed on the angle adjustment component 4 on the arc heat source consumable electrode welding torch 2.

[0039] In some other embodiments, the two-dimensional adjustment component 3 may also be installed on the angle adjustment component 4 on the laser output end 1 .

[0040] Example 4

[0041] The laser welding torch adjustment mechanism in this embodiment is different from that in embodiment 1 in that: Figure 4 As shown, a two-dimensional adjustment component 3 is installed on the laser output end 1 and the arc heat source melting electrode welding torch 2, an angle adjustment component 4 is installed on the two-dimensional adjustment component 3 on the laser output end 1, and an angle adjustment component 4 is also installed on the two-dimensional adjustment component 3 on the arc heat source melting electrode welding torch 2. In actual use, a more comprehensive and larger adjustment range can be obtained.

[0042] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
