Figures 5 to 6 Then to Figure 7 During the process, the first fork rod 8 will Figure 5 When the driving column 14 is stuck in the state (the first fork rod 8 can drive the rotating frame 21 to rotate through the driving column 14), the rotating disc 19 will then drive the rotating frame 21 to rotate 60 degrees counterclockwise (to Figure 7 status shown).

[0026] The upper end of the base plate 1 is fixedly connected to a fixed column 17, and the second fork rod 18 is slidably snap-connected to the fixed column 17, and the lower end of the second fork rod 18 is fixedly connected to a wire brush 16; the wire brush 16 can clean the welding slag of the second workpiece 28 and the first workpiece 27 after welding.

[0027] Three groups of second supporting legs 15 are fixedly connected to the upper end of the base plate 1, and the upper ends of the three groups of second supporting legs 15 are fixedly connected to the top plate 11. The upper end of the top plate 11 is fixedly connected to the second blanking frame 10. Multiple groups of second workpieces 28 are placed in the second blanking frame 10, and the second workpieces 28 fit into the limiting groove 22; when the limiting groove 22 passes directly under the second blanking frame 10, a group of second workpieces 28 falls from the second blanking frame 10 into the limiting groove 22.

[0031] This device is used for welding electromechanical control fixtures. The device is placed on a protective cover ( Figure 8 )Inside.

[0032] In specific operation, when the device is in use, first, multiple groups of first workpieces 27 are placed in the first blanking frame 7, and multiple groups of second workpieces 28 are placed in the second blanking frame 10. The motor 24 is started, and the motor 24 can drive the rotating disc 19 to rotate through the main shaft 25. The rotating disc 19 can drive the second fork rod 18, the first fork rod 8, and the curved rod 4 to move through the second rotating shaft 29. Figures 5 to 6 Then to Figure 7 During the process, the first fork rod 8 will Figure 5 When the driving column 14 is stuck in the state (the first fork rod 8 can drive the rotating frame 21 to rotate through the driving column 14), the rotating disc 19 will then drive the rotating frame 21 to rotate 60 degrees counterclockwise (to Figure 7 shown status), in Figure 7 to Figure 5 When in the state, the first fork rod 8 will be disengaged from the driving column 14. At this time, the rotation of the rotating disk 19 will not drive the rotating frame 21 to rotate. During the rotation of the rotating disk 19, the rotating disk 19 will drive the push block 6 to slide left and right in the guide frame 3 through the second rotating shaft 29, the curved rod 4, and the first rotating shaft 5, thereby pushing the first workpiece 27 that falls into the guide frame 3 to automatically insert into the second workpiece 28.

[0033] When the limiting groove 22 passes directly below the second blanking frame 10, a group of second workpieces 28 fall from the second blanking frame 10 into the limiting groove 22. When the limiting groove 22 containing the second workpieces 28 rotates to the corresponding position of the guide frame 3 ( Figure 7 The status shown is Figure 7 to Figure 5 During the process, the rotating frame 21 will not rotate). Figure 7 to Figure 5During the process, the push block 6 pushes the first workpiece 27 to be inserted into the second workpiece 28. When the second workpiece 28 moves to the corresponding position of the fixed mounting plate 13 ( Figure 5 The status shown is Figures 5 to 7 During the process, the rotating frame 21 will rotate), and the plasma arc welding gun 12 is started to weld the upper and lower gaps between the first workpiece 27 and the second workpiece 28. (The plasma arc welding gun 12 automatically starts when the second workpiece 28 rotates to the welding position and stops immediately after the welding is completed. The plasma arc welding gun 12 is synchronized with the motor 24. When the main shaft 25 drives the second rotating shaft 29 on the rotating disk 19 to rotate to the specified position (when the weld is aligned with the plasma arc welding gun 12), the plasma arc welding gun 12 automatically starts and stops). When the limiting groove 22 with the second workpiece 28 moves to the corresponding position of the wire brush 16, ( Figure 5 The status shown is Figures 5 to 7 During the process, the rotating frame 21 will rotate), and the wire brush 16 can sweep away the welding slag attached to the second workpiece 28. When the limiting groove 22 with the second workpiece 28 rotates to the position of the leakage hole 20, the welded second workpiece 28 will leak out from the leakage hole 20. In this way, the second workpiece 28 and the first workpiece 27 are automatically dropped, automatically assembled, and welded. The automatic cleaning of welding slag and the automatic dropping of the welded finished product are completed in a cycle. The whole process is fully automatic.
