The rotating shaft of the X1 rotary table 234 is in transmission connection with an X driving motor 241 constituting an X rotation adjusting unit provided on the X mount 24a through a set of transmission gears.

The welding assistive device provided by the invention can quickly and conveniently realize the quick welding of the street lamp base structure, and improves the production efficiency of the street lamp base structure.

The method for welding the street lamp base structure by adopting the auxiliary welding tool comprises the steps of clamping an X-shaped connecting piece 105 on a B1 clamping unit 22a of the auxiliary welding tool, then clamping a group of X, Y connecting blocks (X, Y connecting blocks are riveted through X rivet pins in advance) on an A1 clamping unit 21a, and then clamping a Y-shaped connecting piece 106 on a B1 clamping unit 22 a; similarly, another group of X, Y connecting pieces and X, Y connecting pieces are clamped on the clamping units 22B A2 and B2 in the clamping sequence, and a welding device is started to weld the welding joints between the two groups of X, Y connecting pieces and X, Y connecting pieces; adjusting X, Y that the mounting racks are close to each other, clamping X1, X2, Y1 and Y2 bracket legs on the C1 and C2 clamping units 23a and 23b, enabling the X, Y connecting piece and the X1, X2, Y1 and Y2 bracket legs to be in an overlapping state, and starting a welding device to weld the welding joints between the X, Y connecting piece and the X1, X2, Y1 and Y2 bracket legs; adjusting X, Y the distance of the mounting racks from each other and releasing the clamping state of the B1, B2, C1 and C2 clamping units, so that the welded street lamp base structure is detached from the welding auxiliary tool. Therefore, the street lamp base structure can be welded quickly and reliably, the production cost is reduced, and the production efficiency is improved. The welding device can be an automatic welding robot or a welding device operated manually.
