[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 One embodiment of this utility model is a laser handheld welding machine that is easy to adaptively adjust;

[0024] The device includes a limiting sliding rod 3, a laser welding head 14, and a grip adjustment assembly. The output end of the input connection line 13 is connected to the limiting sliding rod 3. The output end of the limiting sliding rod 3 is equipped with the laser welding head 14. A grip adjustment assembly is provided on the outer side of the limiting sliding rod 3. The grip adjustment assembly includes a grip sliding collar 4, an inner arc groove 17, and an electromagnet 18. The grip sliding collar 4 is sleeved on the outer side of the limiting sliding rod 3 and slides on the inner side of both ends of the limiting sliding rod 3. The inner arc groove 17 is symmetrically opened on the inner wall of the grip sliding collar 4. The electromagnet 18 is installed on the inner side of the inner arc groove 17.

[0025] The outer side of the limiting sliding rod 3 is symmetrically provided with arc-shaped slots 15, and a magnet 16 is installed on the inner side of the arc-shaped slots 15. The magnet 16 is magnetically attracted to the electromagnet 18. The outer end of the holding sliding collar 4 is provided with a position adjustment switch 19.

[0026] The two ends of the limiting sliding rod 3 limit the adjustment position of the holding sliding collar 4, restricting the movement range of the holding sliding collar 4 and preventing the user from moving the holding sliding collar 4 to an unsafe position due to misoperation, thus improving the safety and reliability of the equipment. The holding position of the laser welding machine can be adjusted according to the different welding gun usage habits of each person. After the holding sliding collar 4 is adjusted to a suitable position outside the limiting sliding rod 3, the adjustment switch 19 is pressed to supply power to the electromagnet 18. The inner arc groove 17 provides an installation position for the electromagnet 18 while ensuring power supply safety. When the electromagnet 18 is energized, it is magnetically attracted to the magnet piece 16 in the arc groove 15 to realize the adjustment and fixation of the holding sliding collar 4. The adjustment and fixation are achieved by using magnetic attraction.

[0027] In actual welding work, welders may need to adopt different postures, such as standing, squatting, bending over, etc. Different welders have different gripping habits. Some welders prefer to hold the grip forward to obtain better operational flexibility, while others prefer to hold it backward to increase stability. Welders only need to move the gripping sliding collar 4 to the required position, and then make the electromagnet 18 and the magnetic plate 16 magnetically attract each other to complete the adjustment and fixation. The magnetic attraction between the electromagnet 18 and the magnetic plate 16 can provide sufficient fixing force to ensure that the gripping sliding collar 4 will not loosen or shift during the welding process. Even if it is subjected to large vibrations and impacts during the welding process, the gripping position can remain stable.

[0028] Please see Figure 1 and Figure 3 A handheld laser welding machine that is easy to adaptively adjust;

[0029] The device includes a main body 1 and a control console 2. An electric lifting base 6 is installed at the bottom of the main body 1, and casters 7 are installed at the bottom of the main body 1, with the casters 7 located inside the electric lifting base 6. A storage slot 8 is opened at the top of the main body 1, and an input connection cable 13 is placed inside the storage slot 8. The control console 2 is installed at the front of the main body 1, and an output interface 10 is installed at the top of the control console 2. The output interface 10 is detachably connected to the input connection cable 13. A fault alarm light 9 is installed at the top of the control console 2, a support rod 11 is installed at the top of the control console 2, and a pull rod 12 is installed on the front of the control console 2.

[0030] Pulling the lever 12 in conjunction with the moving wheels 7 adjusts the position of the welding machine. After moving to the position, the electric lifting base 6 moves downwards to contact the ground and limit its movement, ensuring the stability of the machine body 1 during use. The storage slot 8 stores the input connection cable 13 and the welding head. The operator holds the adjusted and fixed gripping sliding collar 4 and directs the focused laser beam through the laser welding head 14 to the part to be welded. The energy of the laser beam is absorbed by the material, causing it to heat up and melt rapidly. At the same time, the auxiliary gas protection of the laser welding head 14 prevents oxidation of the molten pool, forming a good weld. The welding parameters are adjusted and controlled through the control console 2. The output interface 10 is connected to the input connection cable 13 to ensure the normal operation of the laser welding head 14. When an abnormality occurs during laser welding, the fault alarm light 9 illuminates to warn the operator. The support rod 11 facilitates the support and placement of the limit sliding lever 3 and the laser welding head 14.

[0031] Please see Figure 1 , Figure 2 and Figure 4 A handheld laser welding machine that is easy to adaptively adjust;

[0032] It includes a gripping sliding collar 4, an electric short lever 20, and a gripping pad 21. The gripping sliding collar 4 is sleeved on the outside of the limiting sliding lever 3. The gripping sliding collar 4 slides on the inside of both ends of the limiting sliding lever 3. The outer side of the gripping sliding collar 4 is symmetrically provided with expansion grooves 5. The electric short lever 20 is installed on the inside of the expansion grooves 5. The extension end of the electric short lever 20 is equipped with a gripping pad 21.

[0033] The expansion groove 5 provides an installation position for the electric short lever 20. When the electric short lever 20 is working, it pushes the grip pad 21 to change the grip diameter of the grip pad 21. The range of use of the grip pad 21 can be adjusted according to the user's hand size and gripping habits. Welders with larger hands can increase the grip diameter to avoid feeling cramped when gripping; welders with smaller hands can decrease the grip diameter to ensure a stable grip.

[0034] Working principle: When using this device, first connect the output interface 10 to the input connection line 13, and then adjust the grip position of the laser welding machine according to the different welding gun usage habits. After adjusting the grip sliding collar 4 to a suitable position outside the limit sliding rod 3, press the adjustment switch 19 to supply power to the electromagnet 18. When the electromagnet 18 is energized, it is magnetically attracted to the magnet piece 16 in the arc-shaped slot 15 to realize the adjustment and fixation of the grip sliding collar 4. Adjust the usage range of the grip pad 21 according to the user's hand size and grip habits. The electric short lever 20 pushes the grip pad 21 until it is adjusted to a comfortable grip position. The user uses the laser welding head 14 to perform laser welding operation through the control console 2.
