At the top of the limit anti - detachment frame 76, there is a steering connection seat 77. The commutation device 7 is arranged with the connecting column 71 at the left front of the welding control frame 1. Inside the connecting column 71, there is a lifting electric cylinder. The connecting column 71 is used to support the mounting seat 72, and the lifting electric cylinder is used to change the overall support height of the mounting seat 72 and its components. The commutation motor 73 is fixed on the panel of the mounting seat 72. The output end of the commutation motor 73 fixes the support setting of the limit anti - detachment frame 76 through the commutation rotating shaft 75. The top of the limit anti - detachment frame 76 establishes a connection with the connection end 83 through the steering connection seat 77. The commutation motor 73 rotates to control the commutation rotating shaft 75 to switch the positions of the first welding disc 81 and the second welding disc 84, realizing the alternating setting of the welded metal mesh cover and a new set of metal mesh covers to be welded. The top of the commutation motor 73 limits its rotational output through the damping anti - detachment seat 74, and reduces the wear of the rotational output of the commutation rotating shaft 75 on the output end of the commutation motor 73, effectively extending the service life of the rotating device.
[0033] Participate Figure 5 And Figure 6 , the two - way welding disc 8 includes a first welding disc 81 and a second welding disc 84. Between the first welding disc 81 and the second welding disc 84, there is a connection end 83. In the center of the first welding disc 81, there is a first cavity 82. In the center of the second welding disc 84, there is a second cavity 85. The two - way welding disc 8 realizes the alternating setting of the metal mesh cover to be welded by setting the first welding disc 81 and the second welding disc 84, providing an automatic feeding device for the metal mesh cover welding work, reducing manual intervention, and improving the metal mesh cover welding efficiency. The structures of the two groups of welding discs are the same. They respectively provide a moving space for the mesh cover rotating motor 67 and its components by setting cavities. That is, during the welding operation, the bottom of the welding disc is placed on two groups of rubber support pads. The mesh cover rotating motor 67 and its components support the metal mesh cover to be welded and drive the metal mesh cover to move horizontally, completing the welding of multiple welding points of the support skeleton at one time.

[0036] In the right inner cavity of the welding control frame 1, there is a mesh cover moving motor. At the output end of the mesh cover moving motor, there is a driving worm. The driving worm is connected to the moving worm 65. The rotation of the mesh cover moving motor causes the driving worm to rotate quantitatively.

The left side panel of the cushion block setting frame 21 fixes the setting of the welding table 23. During operation, the welding table 23 is placed at the bottom of the metal mesh cover to be welded, and the welding frame 24 holds against the support skeleton. The multi-point welding torch 55 presses down to complete the welding operation of the support skeleton.

When the extending rods 52 extend, the pressing seat 53 moves downward by a certain distance, driving the heat insulation connecting frame 54 to act on the multi-point welding gun 55 to perform welding operations on the metal mesh cover and the support skeleton to be welded.
[0040] In the double-station mesh cover automatic row welding device provided by the embodiment of the present invention, a metal mesh cover to be welded is placed on the welding plate at the left front of the welding control frame 1 for the two-way welding plate 8. The welding operation is started on the touch control panel. The reversing device 7 rotates the welding plate with the metal mesh cover to be welded to the welding control frame 1. The lifting electric cylinder controls the welding plate to descend, and the edge of the welding plate is placed on the first rubber cushion block 22 and the second rubber support cushion block 9. At this time, the metal mesh cover to be welded is lifted by the rotating support shaft 68 and its components, and the outer edge welding points of several groups of the first group of support skeletons are placed on the welding frame 24. After the lifting device 5 controls the multi-point welding gun 55 to weld it, the multi-point welding gun 55 moves upward, and the moving worm 65 drives the moving seat 66 and the metal mesh cover to be welded to move to the right, facilitating the multi-point welding gun 55 to weld new welding points; after completing the welding of a group of support skeletons, the second lifting cylinder 69 controls the mesh cover rotating motor 67 to move upward, and rotates the metal mesh cover to be welded to convert the support skeleton for welding; after completing the welding of a single metal mesh cover, the reversing device 7 raises and supports the two-way welding plate 8, rotates the next metal mesh cover to be welded to the welding control frame 1, and continuously performs the next round of welding operations.
