Therefore, laser welding of titanium alloy plates is generally performed under a vacuum environment to improve laser energy utilization, increase weld penetration, and improve weld protection.

[0033] The staff opens the sealing door 1 3, and then neatly stacks a number of titanium alloy plates in the storage box 9. The left and right sides of the storage box 9 are open to facilitate the placement of the titanium alloy plates. Then the staff closes the sealing door 1 3. The sealing door 1 3 and the sealing door 2 4 can seal the processing box 1, and start the vacuum pump 5 to evacuate the processing box 1 to maintain a vacuum environment in the processing box 1. The staff then controls the vertical electric slide 6 to drive the horizontal electric slide 7 to move downward, and the horizontal electric slide 7 drives the laser welding head 8, the connecting plate 12, the guide rail 13 and the push-out The plate 14 moves downward, and the sliding shaft 11 is located at the lower part of the guide rail 13 at this time. The lower part of the guide rail 13 is vertically arranged, so the sliding shaft 11 will not move temporarily, so that the inclined part of the push-out plate 14 has enough time to move to the bottom of the mounting plate 2 to avoid the titanium alloy plate and the push-out plate 14 from colliding.

When the slide shaft 11 is located at the upper part of the guide rail 13, since the upper part of the guide rail 13 is vertically arranged, the slide shaft 11 will stop moving. When the laser welding head 8 moves downward and contacts the position where the two titanium alloy plates are in contact, the horizontal electric slide rail 7 is controlled to drive the laser welding head 8 to move forward, and the laser welding head 8 welds the two titanium alloy plates. After the welding is completed, The vertical electric slide rail 6 is controlled to drive the horizontal electric slide rail 7 to move upward, and the horizontal electric slide rail 7 drives the guide rail 13 and the push-out plate 14 to move upward. The guide rail 13 pushes the slide shaft 11 to make the two push-out plates 10 move away from each other, and the remaining titanium alloy plates in the storage box 9 fall downward. The lower part of the push-out plate 14 is tilted forward, so the push-out plate 14 moves upward to push the welded titanium alloy plates forward, and the welded titanium alloy plates are pushed out for automatic unloading without opening the sealing door 1 3 and the sealing door 2 4, thereby improving work efficiency.

The pressing plate 15 can press the welded titanium alloy plate to prevent the welded titanium alloy plate from tilting upward. When the horizontal electric slide rail 7 moves downward, it drives the lifting plate 26 and the tooth block 27 to move downward. When the tooth block 27 moves downward and meshes with the spur gear 21, the ratchet 25 jams the ratchet gear 23. Therefore, the spur gear 21 will not rotate, the tooth block 27 will rotate upward, the torsion spring 2 is deformed, and when the tooth block 27 moves downward and disengages from the spur gear 21, under the action of the torsion spring 2, the tooth block 27 rotates downward, and when the horizontal electric slide rail 7 moves upward, it will drive the lifting plate 26 and the tooth block 27 to move upward. When the tooth block 27 moves upward and meshes with the spur gear 21, the tooth block 27 drives the spur gear 21 to rotate, and the spur gear 21 drives the rack 22 to move downward, and the rack 22 drives the slide bar 16 downward. The spring 17 is stretched, and the slide bar 16 drives the receiving plate 18 to move downward, so that the receiving plate 18 drops a certain distance, so that the receiving plate 18 can receive more welded titanium alloy plates, which is convenient for the subsequent collection of welded titanium alloy plates. The limiting plate 1 28, the limiting plate 29 and the limiting frame 30 can limit the welded titanium alloy plates on the receiving plate 18 to prevent the welded titanium alloy plates on the receiving plate 18 from falling. When the gold plate is removed, the staff opens the sealing door 1 3 and the sealing door 2 4, and the sealing door 2 4 drives the limit frame 30 to rotate forward, removes the limit frame 30, and then removes the welded titanium alloy plate on the receiving plate 18, and then rotates the connecting shaft 24, and the connecting shaft 24 drives the pawl 25 to rotate, so that the pawl 25 and the ratchet gear 23 are disengaged, and the torsion spring is deformed, and the pawl 25 no longer jams the ratchet gear 23, and under the action of the spring 17, the slide bar 16 and the receiving plate 18 move upward and reset.
