[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] like Figure 1-6 As shown, a steel structure pad welding auxiliary tooling comprises a lower base plate 1, on which an upper base plate 2 is rotatably connected, on which two vertical plates 3 are symmetrically welded, between which a bidirectional screw 4 and a synchronous shaft 5 are rotatably connected, and the top of the vertical plate 3 is rotatably connected to a special-shaped sleeve 6, which is connected to the synchronous shaft 5 through a sprocket structure 7, and a rotating shaft 8 is inserted in the special-shaped sleeve 6, and two frames 9 are symmetrically threaded on the bidirectional screw 4, a round sleeve 10 is penetrated and welded on the top of the frame 9, and the rotating shaft 8 is connected to the round sleeve 10 with bearings, and one end of the rotating shaft 8 is hinged to a placement plate 11 and a telescopic rod 22, and the other end of the telescopic rod 22 is hinged to the placement plate 11.

[0028] A plurality of steering wheels 18 are installed in a circular array at the bottom of the lower base plate 1, and the rotating ends of the steering wheels 18 abut against the lower base plate 1. The upper base plate 2 can rotate, and the steering wheels 18 can carry the entire device. The rotational connection between the upper base plate 2 and the lower base plate 1 can be achieved through a bearing. The bearing is fixed on the lower base plate 1, and the upper base plate 2 is interference-fitted in the bearing to enable it to be rotationally connected to the lower base plate 1.

[0029] Two reinforcing ribs 16 are welded to the bottom of one side of the frame 9 to provide oblique support for the frame 9. Baffles 17 are welded to the upper bottom plate 2 on both sides of the bottom end of the frame 9. The bottom ends of the frame 9 and the reinforcing ribs 16 are slidably connected to the upper bottom plate 2 between the two baffles 17. The baffles 17 play a role of limiting and guiding to prevent the frame 9 from tilting when moving. The synchronous shaft 5 runs through the two frames 9, and the synchronous shaft 5 does not contact the frame 9, so that the movement of the frame 9 and the rotation of the synchronous shaft 5 do not hinder each other.

[0030] One end of the rotating shaft 8 is square and the other end is round. The special-shaped sleeve 6 is a tube with an outer circle and an inner square. The square end of the rotating shaft 8 is inserted into the special-shaped sleeve 6. The round end of the rotating shaft 8 is connected to the round sleeve 10 by a bearing. After passing through the round sleeve 10, the round end of the rotating shaft 8 is hinged at the center of the mounting plate 11.

[0031] When welding the pad, it is necessary to rotate the placement plate 11 to adjust the welding angle. No matter which placement plate 11 is manually rotated, the square end of the rotating shaft 8 connected to it can drive the special-shaped sleeve 6 to rotate. The special-shaped sleeve 6 drives the synchronous shaft 5 to rotate through the sprocket structure 7. The synchronous shaft 5 drives the other placement plate 11 to rotate synchronously through another sprocket structure 7.

[0032] When the two frames 9 move closer to or farther away from each other, since the rotating shaft 8 is connected to the round sleeve 10 by a bearing, the bearing is fixed to the round sleeve 10, and the rotating shaft 8 and the bearing are interference fit, the rotating shaft 8 and the frame 9 move synchronously. Since the square end of the rotating shaft 8 is inserted into the special-shaped sleeve 6, the rotating shaft 8 slides in the special-shaped sleeve 6.

[0033] The outer wall of the round sleeve 10 is threaded with a fixing bolt 19, and the bolt tail of the fixing bolt 19 abuts against the outer wall of the circular end of the rotating shaft 8. After the rotation adjustment angle is completed, welding is required. In order to prevent the placement plate 11 from rotating by itself during welding, the fixing bolt 19 on the outer wall of the round sleeve 10 is tightened to fix the rotating shaft 8.

[0034] The placement plate 11 is square, and is provided with four strip holes 20, which are symmetrically located on the diagonal lines of the placement plate 11, and bolt pairs 21 are bolted to the strip holes 20. The pad flange is usually square, and has four through holes for passing bolts, and the four through holes are all located on the diagonal lines of the pad flange. Therefore, no matter how large or small the pad flange is, its through holes must coincide with the strip holes 20, and the flange is fixed to the strip holes 20 by the bolt pairs 21, and the center of the flange must be aligned with the center of the placement plate 11, so that the pad is centered.

[0035] A lifting rod 12 is welded on the upper base plate 2 , a support rod 13 is inserted at the top of the lifting rod 12 , a fixed clamping plate 14 is welded at one end of the support rod 13 , and a movable clamping plate 15 is bolted to the fixed clamping plate 14 .

[0036] A square sleeve 23 is welded to the top of the lifting rod 12. The lifting rod 12, the square sleeve 23 and the support rod 13 are all made of square tubes. A support plate 24 is welded to one side of the bottom of the fixed splint 14. Studs 26 are welded to both ends of the fixed splint 14. A slot 25 is provided at the bottom of the movable splint 15. The movable splint 15 is slidably connected to the support plate 24 through the slot 25. The stud 26 penetrates the movable splint 15 and is threadedly connected with a clamping nut 27. The square sleeve 23 is threadedly connected with a fixing bolt 19, and the bolt tail of the fixing bolt 19 abuts against the outer wall of the support rod 13.

[0037] A handle 28 is installed at one end of the bidirectional screw 4. When the bidirectional screw 4 is rotated by the handle 28, the bidirectional screw 4 has threads in opposite directions, and the two vertical plates 3 are threadedly connected to the two opposite threads of the bidirectional screw 4, so that the two vertical plates 3 can be synchronously moved closer to or away from each other.

[0038] The working principle of the present invention is: The flange of the pad is usually square with four through holes for bolts. The four through holes are located on the diagonal of the pad. The two flanges of the pad are connected by ribs. The welding forms of the ribs are different. Some are in a well shape and some are cross-shaped. When in use, the prepared flange is passed through the through holes of the flange and the strip holes 20 of the placement plate 11 through the bolt pair 21, so as to be bolted to the strip holes 20 of the placement plate 11. Since the four through holes are located on the diagonal of the flange, no matter how large or small the flange of the pad is, its through holes must coincide with the strip holes 20. The center of the flange must be aligned with the center of the placement plate 11, so that the pad is centered. The two flanges of some pads are not parallel, but inclined. At this time, by shortening or extending the telescopic rod 22, the placement plate 11 is rotated to a certain angle, and the flange is also rotated to the same angle.

[0039] When the bidirectional screw rod 4 is rotated by the handle 28, the bidirectional screw rod 4 has threads in opposite directions, and the two vertical plates 3 are threadedly connected to the two opposite threads of the bidirectional screw rod 4, so that the two vertical plates 3 can be synchronously moved closer to or farther from each other, thereby adjusting the distance between the two flanges according to the length of the rib plate. When the two frames 9 are moved closer to or farther from each other, since the rotating shaft 8 is connected to the round sleeve 10 by a bearing, that is, the bearing is fixed to the round sleeve 10, and the rotating shaft 8 and the bearing are interference fit, the rotating shaft 8 and the frame 9 move synchronously, and since the square end of the rotating shaft 8 is inserted in the special-shaped sleeve 6, the rotating shaft 8 slides in the special-shaped sleeve 6.

[0040] Place the rib plate between the movable clamp plate 15 and the fixed clamp plate 14, and tighten the clamping nut 27. At this time, the rib plate is clamped, and the height of the rib plate is adjusted by the lifting rod 12. The horizontal position of the rib plate is adjusted by sliding the support rod 13 and tightening the fixing bolts 19 on the square sleeve 23. After the rib plate is in place, the two ends of the rib plate are welded to the two flanges.

[0041] Rotate the placement plate 11, and spot weld the other ribs on the two flanges according to the above method. No matter which placement plate 11 is manually rotated, the square end of the rotating shaft 8 connected thereto can drive the special-shaped sleeve 6 to rotate, and the special-shaped sleeve 6 drives the synchronous shaft 5 to rotate through the sprocket structure 7, and the synchronous shaft 5 drives the other placement plate 11 to rotate synchronously through another sprocket structure 7. In order to prevent the placement plate 11 from rotating by itself during welding, tighten the fixing bolts 19 on the outer wall of the circular sleeve 10 to fix the rotating shaft 8.

[0042] After the spot welding is completed, full welding is performed, and the rotation of the operating surface is adjusted by rotating the placement plate 11 and the upper base plate 2, so that the workers do not need to move frequently for welding.

[0043] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should all fall within the scope of protection of the present invention.
