The ultrasonic impact gun 19 is connected to one end of the parallel component by a fastener. The other end of the parallel component is provided with a laser-TIG hybrid welding device. A support component is provided in the middle of the parallel component. The lower end of the support component rests on the workpiece 2 on the operating table 1. A cooling component is provided at the lower end of the ultrasonic impact gun 19.

[0031] The working principle of the above technical solution is as follows: the laser-TIG hybrid welding device includes a TIG welding gun 4 and a laser head 29. The TIG welding gun 4 is connected to the end of the parallel component by a fastener. The TIG welding gun 4 is electrically connected to the welding power supply 3. The laser head 29 is fixed to the end of the parallel component. The laser head 29 is photoelectrically connected to the laser light source emitting device 30. The TIG welding gun 4 and the laser head 29 are both installed on the operating table 1. The welding power supply 3 and the laser light source emitting device 30 are started, and the gap on the workpiece is welded by the laser head 29 and the TIG welding gun 4.

[0032] The ultrasonic impact gun 19 is connected in parallel with the laser-TIG composite welding device through a parallel component to achieve synchronous ultrasonic impact on the weld during the welding process, improve the stress concentration of the weld joint, and thus improve the mechanical properties. The supporting component can be placed against the workpiece 2 and slide on the surface of the workpiece 2 to maintain a stable output of the welding process and ultrasonic impact. In addition, the supporting component is arranged between the laser-TIG composite welding device and the ultrasonic impact gun 19 to block the high temperature, spatter, etc. generated by the laser-TIG composite welding device from affecting the ultrasonic impact gun 19. The cooling component can cool the impacted area to prevent plastic deformation caused by excessive temperature impact, which affects the effect of the ultrasonic impact.

[0033] Example 2

[0034] like Figure 1-7 As shown, the parallel component includes a first connecting frame 5 and a second connecting frame 6, the first connecting frame 5 is slidably connected to the second connecting frame 6, the second connecting frame 6 is provided with a plurality of sockets 17, the first connecting frame 5 is slidably connected to the latch 18, and the latch 18 is inserted through the sockets 17;

[0035] The working principle of the above technical solution is: the TIG welding gun 4 is connected to the first connecting frame 5 through fasteners, and the ultrasonic impact gun 19 is connected to the second connecting frame 6 through fasteners. When the pin 18 is removed, the first connecting frame 5 and the second connecting frame 6 can slide relative to each other, thereby changing the distance between the TIG welding gun 4 and the ultrasonic impact gun 19, and then adjusting the time for the ultrasonic impact gun 19 to impact the location after the TIG welding gun 4 is connected to achieve the best effect.

[0036] Example 3

[0037] like Figure 1-7As shown, the fastener includes a clamping member 7 rotatably connected to the second connecting frame 6, a gear member 8 is fixed to the end of the clamping member 7, the clamping member 7 is fixedly connected to the fastening member 9 by a screw 10, and the ultrasonic impact gun 19 is fixed between the clamping member 7 and the fastening member 9;

[0039] The push rod 12 is fixedly connected to one end of the spring 13, and the other end of the spring 13 is fixed in the second connecting frame 6;

[0040] The working principle of the above technical solution is as follows: the ultrasonic impact gun 19 is placed in the clamping member 7, the fastening member 9 is fastened to the clamping member 7, and the ultrasonic impact gun 19 is fixed between the clamping member 7 and the fastening member 9 by the screw 10, thereby completing the installation and fixation of the ultrasonic impact gun 19. The ultrasonic impact gun 19 is easy and quick to install and disassemble;

[0041] When the button 11 is pressed, the push rod 12 is driven to slide in the second connecting frame 6, and the spring 13 is compressed, and the limit member 15 is driven forward through the connecting rod 14, and the limit member 15 is driven to separate from the gear member 8. The integral fastener can rotate with the second connecting frame 6, and the ultrasonic impact gun 19 is driven to rotate, thereby adjusting the impact angle of the ultrasonic impact gun 19. After the adjustment is completed, the pressing restriction of the button 11 is released, and under the elastic force of the spring 13, the push rod 12 is driven to slide in the opposite direction in the second connecting frame 6, and the limit member 15 is driven to retreat through the connecting rod 14, and the limit member 15 is driven to re-engage with the gear member 8, so that the fastener cannot rotate in the second connecting frame 6, thereby completing the fixation of the ultrasonic impact gun 19. The angle adjustment of the ultrasonic impact gun 19 is convenient and quick. When the ultrasonic impact gun 19 is in the working state, it is arranged perpendicular to the workpiece, which is convenient for impacting the welding position. When the ultrasonic impact gun 19 is in the idle state, it can be turned to a tilted state to reduce the occupied space and facilitate storage.

The connection relationship of the fasteners for fixing the TIG welding gun 4 is as follows: the clamping member 7 is rotatably connected to the first connecting frame 5, a gear member 8 is fixed to the end of the clamping member 7, and the clamping member 7 is fixedly connected to the fastening member 9 by a screw 10. The TIG welding gun 4 is fixed between the clamping member 7 and the fastening member 9;

[0043] A push rod 12 is slidably connected to the first connecting frame 5, a button 11 is fixed to one end of the push rod 12, a connecting rod 14 is fixed to the other end of the push rod 12, an end of the connecting rod 14 is fixedly connected to a limiter 15, and the limiter 15 is engaged with the gear member 8;

[0044] Therefore, the installation and fixing and welding angle adjustment methods of the TIG welding gun 4 are consistent with the adjustment methods of the ultrasonic impact gun 19.

[0045] Example 4

[0046] like Figure 1-7 As shown, handpieces 16 are fixed at both ends of the first connecting frame 5;

[0047] The working principle of the above technical solution is as follows: the hand-held pieces 16 provided at both ends of the first connecting frame 5 can be hand-held to drive the TIG welding gun 4 and the ultrasonic impact gun 19 to move, thereby facilitating welding and impacting the workpiece.

A torsion spring is provided between the pawl 26 and the first connecting frame 5.

[0051] The working principle of the above technical solution is: rotate the pawl 26 to separate the pawl 26 from the support rod 27, move the support rod 27 up and down, and then adjust the support height to achieve a comfortable welding height;

[0052] The bent frame 28 at the lower end of the support rod 27 rests on the surface of the workpiece, and both ends of the bent frame 28 are bent upward to prevent the bent frame 28 from hitting the uneven surface of the workpiece when sliding on the surface of the workpiece;

[0053] The support rod 27 not only plays a supporting role, but also is wide, which can prevent the high temperature and spatter generated by the TIG welding gun 4 from affecting the ultrasonic impact gun 19.

[0054] Example 6

[0055] like Figure 1-7 As shown, the cooling component includes a fan 21, which is fixed on the operating table 1. The fan 21 is connected to the sleeve 23 through a connecting pipe 22, and the sleeve 23 is fixed to the end of the ultrasonic impact gun 19;

[0056] The front end of the sleeve 23 is evenly provided with a plurality of air outlets 24;

[0057] The working principle of the above technical solution is: start the fan 21, the fan 21 blows the air from the connecting pipe 22 into the sleeve 23, and then blows the air to the impact point of the ultrasonic impact gun 19 through multiple air outlets 24 evenly arranged at the front end of the sleeve 23. It can blow air around the impact point of the ultrasonic impact gun 19 at the same time. Compared with the traditional one-sided blowing device, the cooling effect is better.
