The upper mounting frame 3 is provided with a plurality of upper pressing structures, and the number of the upper pressing structures corresponds to the specification of the well lattice steel bar truss to be welded.

As shown in fig. 1 to 5, the pressing structure includes a lifting cylinder 4 fixed to an upper mounting frame 3 through a connection member, a pressing block 5 provided at the bottom of the lifting cylinder 4, and an upper electrode 6 provided at one side of the pressing block 5. Be provided with the lower mounting bracket 7 that can reciprocate in the vertical direction on the base 1, be provided with down slide rail 8 on the lower mounting bracket 7, be provided with the movable table 9 that can follow down slide rail 8 lateral shifting down on the slide rail 8, be provided with on the movable table 9 with the bearing structure who pushes up the structure one-to-one, bearing structure is including fixing bracing piece 10 on the base 1, fix bracing piece 10 top and be located the supporting shoe 11 under the corresponding push up structure, the upward perk of supporting shoe 11 one end forms fender 12, the supporting shoe 11 other end is provided with bottom electrode 13. The compression, positioning and welding of the lower chord member and the truss unit can be completed by matching the upper compression structure with the supporting structure, and the concrete flow comprises the following steps: the upper pressing structure and the supporting structure are displaced to generate a bit of dislocation through transverse movement, the lower chord member and the truss unit to be welded are sent between the upper pressing structure and the supporting structure through a stepping device in a specific position relation, each lower chord member to be welded and the truss unit corresponding to the lower chord member correspond to one group of upper pressing structure and the supporting structure, after the positions of the lower chord member and the truss unit to be welded are moved in place (the heights of the lower chord member and the truss unit correspond to the heights of the upper surfaces of the supporting blocks 11), the supporting blocks 11 are driven by the movable table 9 to transversely move close to the lower chord member and the truss unit until the blocking piece 12 abuts against the lower chord member and the truss unit, then the pressing block 5 is pressed down until the pressing block 5 presses the lower chord member and the truss unit between the pressing block 5 and the supporting blocks 11, the upper electrode 6 and the lower electrode 13 on the pressing block 5 and the supporting block 11 can weld the pressed parts, after welding is completed, the upper pressing structure is moved up to the original position, and the lower chord member and the truss unit continue to move until the next welding position is located between the corresponding upper pressing structure and the supporting structure through the stepping device.
