[0002] Laser welding machines are widely used in the welding process of some thin-walled materials and precision parts due to their fast welding speed, fine and beautiful welds, etc. However, there are still some problems with the laser welding machines on the market when they are used, such as:

[0003] The patent name disclosed in the prior art with application number "CN202011033479.0" is "A laser welding machine convenient for adjusting welding angle". It discloses that the workpiece with welding is placed on the surface of the welding plate, and the rotating block is manually driven to rotate, so that the threaded rod rotates to drive the clamping plate to slide inward in the slide groove through the key block until it fits with the workpiece, and the workpiece is stably limited and clamped. The worm is driven by the motor to rotate, so that the worm wheel rotates, and the gear is driven to rotate, so that the conveyor belt starts to rotate, and the connecting block is driven by the conveyor belt to drive the slider to slide back and forth in the slide rail, so that the sliding column in the sliding cylinder slides up and down, and the connecting plate and the welding plate are turned over, and the turning angle is adjusted according to the actual needs of the user. The setting of this device realizes the adjustment of the rotation angle of the welded workpiece according to the actual needs of the user through the fixing mechanism and the rotating mechanism, and the rotation angle is finely adjusted, and the laser welding equipment is used for welding, which reduces the labor intensity of the staff, saves time and effort, improves the work efficiency of the user, and ensures the safety of use.

[0005] The laser welding machine mentioned above adjusts the welding angle through the arc-shaped adjustment groove of the angle adjustment member. However, since only the angle adjustment member for adjusting in the up-down direction is provided, the laser welding head can only be adjusted at multiple angles in the up-down direction, and cannot be adjusted at multiple angles in the left-right direction, and thus cannot meet different welding requirements, affecting the subsequent welding quality;

The rear side of the second linkage plate 16 is arranged directly below the left side of the first linkage plate 13. A second linkage groove 161 with a fan-shaped structure is provided above the rear side of the second linkage plate 16.

[0057] The first limit support frame 19 and the second limit support frame 22 are both arranged in a "7"-shaped structure, and the rear ends of the first limit support frame 19 and the second limit support frame 22 are slidably connected to the groove of the inner wall of the installation frame 8, a limit rod 21 is installed in the groove of the left inner wall of the installation frame 8, and the outer side of the limit rod 21 is slidably connected to the second limit support frame 22, and two adsorption blocks 20 are symmetrically installed inside the rear side surface of the installation frame 8. The rear sides of the first limit support frame 19 and the second limit support frame 22 are both in contact with the adsorption block 20, and the adsorption block 20 and the first limit support frame 19 and the second limit support frame 22 are connected. The materials of the support frame 19 and the second limit support frame 22 are all magnet block materials, and the first limit support frame 19 and the second limit support frame 22 have opposite magnetic poles to the adsorption block 20. An electric push rod 14 is installed inside the mounting frame 8. The electric push rod 14 is arranged on the left side of the support column 18. A linkage assembly is installed at the front end of the electric push rod 14. The linkage assembly includes a mounting plate 24. The mounting plate 24 is arranged in the through groove 132. A control rod 241 is installed inside the front side of the mounting plate 24, and a linkage block 242 is installed on the outer side of the control rod 241.

[0058] The linking block 242 forms a rotating structure with the mounting plate 24 through the control rod 241. The linking block 242 is engaged with the first linking groove 133 and the second linking groove 161. A vortex spring 181 is nested and connected to the outer side of the front end of the support column 18. One end of the vortex spring 181 is connected to the support column 18, and the other end of the vortex spring 181 is connected to the adjustment frame 11.

[0059] First, move the entire laser welding machine into the working area. After arriving at the working area, place the workpiece to be welded on the workbench 1, and then use external fixtures to fix the workpiece to be welded on the workbench 1. Then, adjust the angle of the laser beam in the laser welding head assembly 9 according to the position where the workpiece needs to be welded and the shape of the workpiece to meet different usage requirements. When it is necessary to adjust the laser beam in the laser welding head assembly 9 at multiple angles in the left and right directions, manually slide the first angle adjustment mechanism 17 left and right on the outside of the adjustment rod 131 above the first linkage plate 13, so that the first angle adjustment mechanism 17 is at the upper left rear or upper right rear of the adjustment frame 11. After adjusting the position of the first angle adjustment mechanism 17, the linkage block 242 in the linkage assembly is engaged and connected in the first linkage groove 133. Then, start the electric push rod 14 at this time, and the output end of the electric push rod 14 The mounting plate 24 and the linkage block 242 are driven to move forward together. At this time, the linkage block 242 drives the first linkage plate 13 to move forward together, and then the first linkage plate 13 slides on the outside of the support column 18. At the same time, the first limit support frame 19 at the right rear side of the first linkage plate 13 slides forward in the groove on the right side of the mounting frame 8, thereby ensuring that the first linkage plate 13 stably drives the first angle adjustment mechanism 17 to move forward. When the first angle adjustment mechanism 17 moves to contact with the adjusting frame 11, the inclined first angle adjustment mechanism 17 will apply a downward pressure to the left or right side of the adjusting frame 11, and then the adjusting frame 11 rotates left or right with the support column 18 as the center. At this time, the vortex spring 181 accumulates force, and then the adjusting frame 11 drives the supporting plate 10 and the laser welding head assembly 9 to rotate at multiple angles in the left and right directions. Therefore, the laser beam in the laser welding head assembly 9 can be adjusted at multiple angles in the left and right directions.

[0060] Then the laser welding head assembly 9 can perform welding operations on the workpiece, by sliding the sliding frame 7 left and right on the second slide rail 5, and the second slide rail 5 slides forward and backward on the first slide rail 4, and the lifting control assembly 6 of the electric telescopic rod can drive the mounting frame 8 and the laser welding head assembly 9 to move downward, so that the laser welding head assembly 9 can be well moved for welding. This part is the prior art and will not be introduced in detail here. After the welding is completed, when it is necessary to reset the angle of the laser welding head assembly 9, as shown above, at this time, the electric push rod 14 drives the first linkage plate 13 to move backward through the linkage assembly, and the first linkage plate 13 drives the first angle adjustment mechanism 17 to move backward, so that the first angle adjustment mechanism 17 is separated from the adjustment frame 11, and the adjustment frame 11 is reset by the reverse rotation of the vortex spring 181, so that the adjustment frame 11 drives the laser welding head assembly 9 to reset well.

[0061] When it is necessary to perform multi-angle adjustment of the laser beam in the laser welding head assembly 9 in the up and down directions, first manually rotate the threaded rod 26 in the support frame 15 clockwise or counterclockwise. At this time, the threaded rod 26 drives the second angle adjustment mechanism 25 connected by the outer thread to move upward or downward, so that the rack assembly 251 on the inner wall above the second angle adjustment mechanism 25 is later meshed and connected with the transmission gear 231, or the rack assembly 251 on the inner wall below the second angle adjustment mechanism 25 is later meshed and connected with the transmission gear 231, and then manually rotate the control rod 241 in the linkage assembly counterclockwise. At this time, the control rod 241 drives the linkage block 242 to rotate counterclockwise, so that the linkage block 242 rotates from the through groove 132 to the second linkage groove 161. At this time, the linkage assembly is separated from the first linkage plate 13 and is not in contact. Then start the electric push rod 14, and the output end of the electric push rod 14 drives the mounting plate 24 in the linkage assembly to move forward. At this time, the mounting plate 24 drives the second linkage plate 16 to move forward through the linkage block 242. The second limit support frame 22 on the rear side of the second linkage plate 16 slides stably on the outer side of the limit rod 21 in the left groove of the mounting frame 8, ensuring that the second linkage plate 16 stably drives the support frame 15 and the second angle adjustment mechanism 25 to move forward, so that the rack assembly 251 on the inner side above the second angle adjustment mechanism 25 is in contact and meshing with the transmission gear 231, or the rack assembly 251 on the inner side below the second angle adjustment mechanism 25 is in contact and meshing with the transmission gear 231. As a result, when the second angle adjustment mechanism 25 moves forward, it drives the transmission gear 231 and the rotating rod 23 to rotate clockwise or counterclockwise, and then the rotating rod 23 drives the laser welding head assembly 9 and the supporting plate 10 to rotate at multiple angles in the up and down directions, and then the laser beam in the laser welding head assembly 9 can be adjusted at multiple angles in the up and down directions. When the laser welding head assembly 9 needs to be reset later, it only needs to drive the second angle adjustment mechanism 25 to move backward and reset through the electric push rod 14, so that the rack assembly 251 is separated from the transmission gear 231.

[0062] Thereby, the laser welding machine can adjust the laser beam in the laser welding head assembly 9 in multiple directions and at multiple angles according to the shape of the workpiece and the welding requirements of the workpiece, so that the adjusted laser beam can be well aligned with the center of the weld, avoiding the position of the laser beam deviating from the weld and causing welding defects, thereby improving the quality of welding and ensuring the reliability of welding.

[0063] At the same time, as shown above, similarly, when the first limit support frame 19 and the second limit support frame 22 are moved in the opposite direction and reset, since the first limit support frame 19 and the second limit support frame 22 are both made of magnet block materials, at this time, the rear ends of the first limit support frame 19 and the second limit support frame 22 are adsorbed with the adsorption block 20 made of magnet block material in the installation frame 8 by opposite magnetic poles, thereby ensuring the stability of the first limit support frame 19 and the second limit support frame 22 when not in use.

[0064] Embodiment 2: The laser welding machine provided with a laser beam multi-angle adjustment mechanism in this embodiment can quickly ensure the stability of the adjustment frame 11 and shorten the shaking time of the adjustment frame 11 when the adjustment frame 11 is reset. For the specific structure, refer to the attached Figure 3-Figure 5 And attached Fig.11 As shown, on the basis of Example 1, a protrusion 191 is installed on one side of the first limit support frame 19, the highest point of the protrusion 191 is higher than the highest point of the first limit support frame 19, the front side of the protrusion 191 is inclined, and the front side of the protrusion 191 is fitted with the rear end of the self-thrusting rod 121 in a "7" shape structure, the rear end of the self-thrusting rod 121 passes through the right side of the mounting frame 8, and a connecting spring 122 is nested and connected to the outer side of the rear end of the self-thrusting rod 121, one end of the connecting spring 122 is connected to the right side of the mounting frame 8, and the front end of the self-thrusting rod 121 is connected to the stable control frame 12; the left inner wall of the stable control frame 12 is connected to the right side of the adjustment frame 11, the stable control frame 12 is arranged in a "U" shape, and the upper and lower side surfaces of the stable control frame 12 are inclined.

[0065] When the first linkage plate 13 moves forward, the first limit support frame 19 at the right rear side of the first linkage plate 13 will move forward together. At this time, the first limit support frame 19 drives the protrusion 191 to move forward. At this time, the inclined surface of the front side of the protrusion 191 will apply a rightward thrust to the rear end of the self-push rod 121, so that the rear end of the self-push rod 121 slides to the right in the right side surface of the installation frame 8. At this time, the front end of the self-push rod 121 drives the stable adjustment frame 12 to move right. At this time, the connecting spring 122 accumulates force, so that the stable adjustment frame 12 is separated from the right side surface of the adjustment frame 11, and then it is convenient for the first angle adjustment mechanism 17 to contact the adjustment frame 11 in the later stage to adjust the rotation of the adjustment frame 11 in the left and right directions. When the first linkage plate 13 drives the first angle adjustment mechanism 17 to move backward, at this time, the first angle adjustment mechanism 17 is separated from the adjustment frame 11, and the adjustment frame 11 is adjusted by the vortex spring When the stored force of spring 181 is used for reverse rotation and reset, as shown above, similarly, the first linkage plate 13 drives the first limit support frame 19 to move backward, and the first limit support frame 19 drives the protrusion 191 to move backward. At this time, the protrusion 191 does not apply a rightward thrust to the self-push rod 121, and then the self-push rod 121 automatically moves to the left through the stored force of the connecting spring 122. At this time, the front end of the self-push rod 121 drives the smooth adjustment frame 12 to move to the left and reset, and then the smooth adjustment frame 12 contacts with the adjustment frame 11 when moving to the left, so that the smooth adjustment frame 12 can limit the adjustment frame 11 well, so that the adjustment frame 11 can quickly remain motionless, avoiding the adjustment frame 11 from repeatedly shaking for a long time when it is reset by the vortex spring 181, thereby protecting the laser welding head assembly 9 and avoiding the laser welding head assembly 9 from shaking and damage, thereby ensuring the stability of the adjustment frame 11.

[0066] Embodiment 3: The laser welding machine provided with a laser beam multi-angle adjustment mechanism in this embodiment can automatically control the rotation of the control rod 241. The specific structure is shown in the attached Fig. 9 As shown, the area of ​​the mounting disk 24 can be designed to be larger, and then a micro servo motor can be installed in the mounting disk 24, so that the output end of the micro servo motor is connected to the rear end of the control rod 241, and then the control rod 241 can be driven to rotate by the micro servo motor later, so that the control rod 241 drives the linkage block 242 to rotate into the first linkage groove 133 or the second linkage groove 161, without manually rotating the control rod 241, so that the entire laser welding machine is more automated when in use, reducing the workload of the staff, thereby completing a series of tasks.
