Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, specifically a positioning structure for a laser-arc composite welding head. Background Technology
[0002] With continuous societal development, energy issues are becoming increasingly prominent, leading to a trend towards lightweight materials, particularly lightweight metals such as aluminum, magnesium, and titanium, whose proportion in GDP is gradually increasing. High-strength aluminum alloys possess advantages such as low density, high strength, excellent corrosion resistance, good weldability, and heat treatability, making them widely used in aerospace, marine, high-speed train, and armored vehicle fields. Currently, 7B52 aluminum alloys are typically welded using processes such as tungsten inert gas (TIG) welding and metal inert gas (MIG) welding. For 7B52 aluminum alloys with a thickness exceeding 15mm, while TIG welding is simple to operate and produces excellent weld quality, its welding efficiency is low. MIG welding offers high deposition rates and efficiency when welding thick plates, but it often suffers from internal defects such as porosity, lack of fusion, and cracks. Current technologies for 7B52 aluminum alloys suffer from two major problems: poor quality and low efficiency.
[0003] Currently, it is difficult to accurately determine the relative position between the laser spot in the laser head of the laser arc welding device and the welding wire in the arc welding gun. When the equipment is performing positioning welding, it is necessary to ensure that the connection does not loosen when it is moved. Moreover, when the welding head is adjusted, its edge is also very easy to collide with the connecting parts. Collisions will reduce the accuracy of the welding device. Therefore, a positioning structure for the laser arc welding head is proposed. Utility Model Content

[0030] Please see Figure 1-6A laser-arc composite welding head positioning structure includes a positioning component 100, a left welding component 200, and a right welding component 300. One end of the positioning post 110 is provided with a connecting seat 120, and the other end of the positioning post 110 is provided with a platform 150.

Pairs of reinforcing ribs 130 are arranged at the bottom of the guide groove 140, which provide stable support to the guide groove 140 during operation and allow for precise positioning of the left welding component. The sliding of component 200 and right welding assembly 300 serves as a guide, and the positioning post 110 acts as an isolation mechanism, effectively preventing collisions between the left welding assembly 200 and right welding assembly 300 during gap adjustment. The left welding assembly 200 includes a left slide 210 disposed on the inner wall of the sink trough 160. A left mounting bracket 220 is provided on one side of the outer wall of the left slide 210. A left locking assembly 230 is provided on the inner wall of the left slide 210. A left protective pad 240 is provided on the outer wall of the left slide 210. A left welding mechanism 250 is provided on the outer wall of the left slide 210. The left mounting bracket 220 includes a lower left connecting block 221 disposed on one side of the left slide 210.

The left locking assembly 230 includes a left threaded post 231 disposed on the inner wall of the left slide 210. A left tightening rod 232 is installed at one end of the left threaded post 231, and a left friction block 233 is installed at the other end of the left threaded post 231. The left welding mechanism 250 includes a left welding table 251 disposed on the outer wall of the left slide 210. A welding head 252 is provided on one side of the left welding table 251, and a drive motor 253 is provided on the other side of the left welding table 251. A left tightening block 254 is provided on the outer wall of the left welding table 251. The right welding assembly 300 includes a right slide 310 disposed on the inner wall of the sinkhole 160. A right mounting bracket 320 is provided on one side of the outer wall of the right slide 310, and a right lock is provided on the inner wall of the right slide 310. The right slide 310 has a locking component 330, a right slide 340 with a pin 340 on its outer wall, a right protective pad 360 on its inner wall, a right welding mechanism 350 on its outer wall, a right mounting bracket 320 including a lower right connecting block 321 on one side of the right slide 310, a right connecting rod 322 on one side of the right mounting bracket 320 away from the right slide 310, a right limiting block 323 on the other end of the right connecting rod 322, a right locking component 330 including a right threaded post 331 on the inner wall of the right slide 310, a right tightening rod 332 on one end of the right threaded post 331, a right friction block 333 on the other end of the right threaded post 331, and a right welding mechanism 350 including a right welding table 351 on the outer wall of the right slide 310.The outer wall of the right welding table 351 is equipped with a drive motor 253 and a welding rod 352. The right protective pad 360 and the right slide table 310, and the left protective pad 240 and the left slide table 210 are slidably connected. Both the right protective pad 360 and the left protective pad 240 are made of natural rubber, as are the right welding mechanism 350 and the left protective pad 240. This ensures that when the left welding table 251 and the right welding table 351 rotate, their edges directly contact the left protective pad 240 and the right welding mechanism 350, thereby effectively... To prevent the left welding platform 251 and the right welding platform 351 from colliding with the left slide 210 and the right slide 310 during rotation, the left threaded post 231 and the left slide 210, and the right threaded post 331 and the right slide 310 are all fixed together by threaded connections. The left friction block 233 and the right friction block 333 are both located on the inner walls of the left mounting bracket 220 and the right mounting bracket 320. The left welding platform 251 and the right welding platform 351 are rotatably connected to the left slide 210 and the right slide 310, and the drive motor 253 and the right turning block 353 are connected to the left welding platform 251 and the right welding platform 351 by means of communication. Fixed via threaded connections, the left friction block 233 and the right friction block 333 are both located on the inner walls of the left mounting bracket 220 and the right mounting bracket 320. When the left slide table 210 and the right slide table 310 are fixed, the operator can directly turn the right screw rod 332 and the left screw rod 232. Through the threaded connection between them and the left mounting bracket 220 and the right mounting bracket 320, the friction between the left friction block 233 and the right friction block 333 and the inner wall of the slide groove 170 is increased, thereby fixing the left slide table 210 and the right slide table 310 in a stable position. Furthermore, when the angle between the welding rod 352 and the welding head 252 needs to be adjusted... During adjustment, the worker can directly turn the right turning block 353 and the left turning block 254 to control the tightness of the rotation of the left welding table 251 and the right welding table 351. After adjustment, the worker can continue to turn the right turning block 353 and the left turning block 254 to ensure the stability of the fixation. The left limit block 223 and the right limit block 323 are slidably connected to the guide groove 140. When the left limit block 223 and the right limit block 323 slide, the guide groove 140 can guide the left limit block 223 and the right limit block 323, thereby effectively preventing their position from shifting during the transfer process.
[0031] Working principle: When the equipment is needed, the operator can directly turn the right screw rod 332 and the left screw rod 232. Through the threaded connection between them and the left mounting bracket 220 and the right mounting bracket 320, the left slide table 210 and the right slide table 310 are fixed in a stable position. After the fixing is completed, the right screwing block 353 and the left screwing block 254 are turned again to control the tightness of the rotation of the left welding table 251 and the right welding table 351 and adjust the rotation angle.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
