The rivet holes 11 formed on the vertical plates 9 by the drilling jig 10 correspond to the positions of the holes on the rear follower plate seat 7 and the front follower plate seat 8. The vertical plates 9, the rear follower plate seat 7 and the front follower plate seat 8 are positioned by positioning pins passing through the holes and rivet holes 11 on the rear follower plate seat 7 and the holes and rivet holes 11 on the front follower plate seat 8. The riveting positioning clamping device located above the follower plate seat positioning block 2 clamps the rear follower plate seat 7 and the vertical plates 9 on both sides thereof to realize the positioning, clamping and riveting of the frame traction beam. Specifically, the sub-plate seat positioning block 2 is composed of a middle seat plate 4 and a bottom plate 5 arranged on both sides of the lower end of the middle seat plate 4. Two positioning notches 6 are formed on the left and right side walls of the middle seat plate 4. The lower ends of the two side walls of the vertical plate positioning block 1 and the two sides of the outer end surface of the positioning platform 3 are formed with positioning ridges 12. The vertical plate 9 is placed on the positioning ridges 12 at the lower ends of the two side walls of the vertical plate positioning block 1 and is tightly attached to the side walls of the vertical plate positioning block 1, and the notched ends of the vertical plate 9 are against the positioning ridges (12) on both sides of the outer end surface of the positioning platform 3; Specifically, the riveting positioning clamping device includes two L-shaped long pull rods 13, an L-shaped short pull rod 16, and a top column 14 and an adjusting bolt 15, the two L-shaped long pull rods 13 and the L-shaped short pull rods 16 are distributed in a cross structure and the intersection of the four rods of the L-shaped long pull rods 13 and the L-shaped short pull rods 16 is fixedly connected by a right-angle plate 17, the lower ends of the L-shaped long pull rods 13 and the L-shaped short pull rods 16 are fixed with screw sleeves 18 and the adjusting bolts 15 connected to the top column 14 at the ends are adapted to be screwed together with the screw sleeves 18, the connecting bolts 23 fixed at the middle of the four right-angle plates 17 are screwed together with the screw holes 24 at the middle of the upper end surface of the slave plate seat positioning block 2, and the top column 14 is used to clamp the two vertical plates 9 and the rear slave plate seat 7 by rotating the adjusting bolts 15;Specifically, the drilling template 10 includes an upper template 22 and a base plate 19.
