[0037] The structure and use principle of the fixed base 2, lifting assembly 4, working box 5 and welding assembly 7 in the utility model have been disclosed in a kind of aluminum-to-nickel automatic laser welding machine for adjusting the position of the welding gun disclosed in Chinese patent application No. 201921767249.X. Its working principle is that when performing laser automatic welding on the aluminum-to-nickel tab, first fix the aluminum-to-nickel tab to be welded on the upper surface of the fixed base 2, then hold the first handle and start to rotate the first turntable, the rotation of the first turntable drives the lead screw to rotate, thereby driving the lead screw nut to rise and fall, thereby driving the working box 5 to rise or fall, thereby adjusting the Z-axis position of the welding gun body, then press the work button, the work button controls the push rod motor to start working, thereby controlling the electric push rod to start to extend and shorten, thereby driving the welding box forward or backward, Thereby adjusting the Y-axis position of the welding gun body, then holding the second handle and starting to rotate the second turntable, the rotation of the second turntable drives the rotation of the shaft and thus drives the rotation of the driving wheel. Since a pull wire is fixedly connected to the outer side of the driving wheel, when the driving wheel rotates, the driving wheel starts to rotate and retract the wire, thereby pulling the welding gun body, thereby adjusting the X-axis position of the welding gun body. Since a spring is fixedly connected to the left end of the welding gun body, when the welding gun body is pulled to the right by the pull wire, the spring undergoes elastic deformation, thereby applying a reverse force to the welding gun body. At this time, continue to rotate the second turntable, and when the fixing hole fixed on the upper surface of the second turntable and the fixing hole fixed on the upper surface of the welding box are in a coaxial position, insert the fixing rod into the fixing hole to prevent the welding gun body from moving in the opposite direction under the action of the spring. At this time, power on the entire system and start welding.

[0038] The working principle and use process of the utility model: the utility model is used for laser welding of aluminum-to-nickel pole ears. When in use, the aluminum-to-nickel pole ears are placed on the fixed base 2 and fixed, and then the welding component 7 is adjusted to a suitable position. After the height is adjusted, the handle of the lifting component 4 is fastened by the fastening component 6, so that it can work. When working, the harmful gas generated is adsorbed and processed by the adsorption component 3. When the fastening component 6 is in use, the pressing rod 62 is pressed, and the pressing rod 62 drives the extrusion block 66 to move and compress the return spring 67. When the pressing rod 62 drives the fastening seat 63 to move, so that the fastening plate 64 and the turning handle of the lifting component 4 are abutted, the pressing rod 62 is continued to be pressed, so that the fastening plate 64 moves in the fastening seat 63 to compress the fastening spring 65. When the pressing rod 62 moves to the fixing hole and When the fixing rods 68 overlap, the fixing rods 68 are inserted into the fixing holes to fix the pressing rods 62, thereby fastening the turning handles through the cooperation of the fastening plates 64 and the fastening springs 65, so that when the device is in use, it is convenient to fasten the handles of the lifting assembly 4, thereby improving the stability after lifting. When the adsorption assembly 3 is in use, the exhaust fan 33 is started, and the exhaust fan 33 generates suction, and the generated harmful gases are sucked into the adsorption box 31 through the smoke hood 32, filtered and adsorbed through the filter 35 and the adsorption net 36, and then discharged. When the filter 35 and the adsorption net 36 need to be replaced, the limit plug 38 is removed, and then the sealing plug cover 37 is opened, and then the placement box 34 can be pulled out, and the filter 35 and the adsorption net 36 are replaced, so that when the device is in use, it is convenient to adsorb the harmful gases generated during welding.
