[0029] The bracket 10 is fixed on the frame 7, and the bracket 10 is provided with a positioning block 13 located above the storage platform 8. The positioning block 13 can extend into the interior of the distribution box 1 to abut against the inner walls of the two adjacent side panels 3. Figure 3 and Figure 5As shown, the positioning block 13 has a support surface 33 that abuts against the bottom of the connecting plate 5, a first positioning surface 31 that abuts against the second vertical plate 6, and a second positioning surface 32 that abuts against the flange 30. The positioning block 13 has a second avoidance groove 21 that is arranged corresponding to the welding corner of the distribution box 1.

[0034] The working principle of the automatic angle welding machine for distribution box of this embodiment is as follows:

[0035] Before welding, the two adjacent first vertical plates 4 of the distribution box 1 have been welded. During welding, the distribution box 1 is placed on the storage table 8 so that the bottoms of the two side panels 3 are respectively against the two positioning bars 29. The lifting assembly 9 drives the storage table 8 to move upward until the positioning block 13 is located inside the distribution box 1. The second driving member 20 drives the second clamping block 17 to move forward, thereby cooperating with the positioning block 13 to clamp the two adjacent second vertical plates 6 into position. Then, the two first driving members 16 drive the two first clamping blocks 15 to move toward the middle position, thereby clamping the two adjacent first vertical plates 4. The welding gun 23 first welds the two adjacent connecting plates 5 from the outside of the distribution box 1, and then moves to the inside of the distribution box 1 to weld the two adjacent second vertical plates 6 and the two adjacent flanges 30. The above process only welds one corner of the distribution box 1.

[0036] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
