[0027] In this embodiment, a pair of guide blocks 43 are also provided on the bottom frame 21. The paired guide blocks 43 are respectively located on both sides of the conveying guide rail and are guided to move along the conveying guide rail.

The bottom motor drives the bottom gear to rotate so as to drive the bottom frame 21 to move along the conveying track 1. A bottom substrate 211 is arranged on the bottom frame 21 in a vertically guiding manner, and a plurality of guiding wheels 25 are movably arranged on the bottom substrate 211. The guiding wheels 25 on the bottom substrate 211 are used to support the longitudinal bars at the bottom of the stirrups.

This not only improves the assembly efficiency of the stirrups and the longitudinal bars, but also makes the alignment of the positions of the stirrups and the longitudinal bars more accurate, reduces the dimensional error of the rectangular steel bar skeletons, and thus greatly improves the production and manufacturing efficiency of the rectangular steel bar skeletons.

[0034] The bottom substrate 211, the top substrate 241, the left substrate 221, and the right substrate 231 are all provided with odd control components and even control components. The odd control components are used to adjust the adjacent spacing of the guide wheels 25 located at odd positions, and the even control components are used to adjust the adjacent spacing of the guide wheels 25 located at even positions. In an embodiment of the present application, the odd control components and the even control components respectively control the spacing between the guide wheels 25 at odd positions and even positions, so as to more conveniently control the spacing between the longitudinal bars, so that the distribution of the longitudinal bars can be applicable to more different sizes of stirrups, thereby enabling the device to be applicable to the precise assembly construction of rectangular steel bar skeletons of different sizes.

[0035] The odd control components include at least two odd guide rails 26. An odd guide block 262 is movably arranged on the odd guide rails 26 in a guiding manner. A guide wheel 25 is rotatably arranged at the end of the odd guide block 262.

[0061] In an embodiment of the present application, the top of the stirrup is clamped by the opposite movement of the left clamping block 46 and the right clamping block 47, and the clamping of the stirrup is released by the back movement of the left clamping block 46 and the right clamping block 47; thus, the stirrup is straightened during the relative threading operation and welding operation of the stirrup and the longitudinal bars.

[0062] In this embodiment, a plurality of air cylinders can be arranged on the straightening frame 41, and the output ends of the plurality of air cylinders are connected to the straightening substrate 42 to drive the straightening substrate 42 to move in the vertical direction.

[0063] A plurality of jacking mechanisms 5 are arranged at the bottom of a pair of conveying guide rails, and the jacking mechanisms 5 are used for temporarily supporting the stirrup clamp 3.

[0064] A pressing block 29 is arranged on the upper part of the guide wheel 25, and the pressing block 29 moves up and down through a cylinder to press the longitudinal bars on the guide wheel 25.

[0065] In this embodiment, 5 longitudinal bar supporting units 2 are arranged on the conveying track 1. The forwardmost longitudinal bar supporting unit 2 is not provided with a straightening mechanism 4, and the other four longitudinal bar supporting units 2 are all provided with a straightening mechanism 4. Moreover, the respective base plates on the forwardmost longitudinal bar supporting unit 2 and the guide wheels 25 face backward. The forwardmost longitudinal bar supporting unit 2 is used for dragging the rectangular steel bar skeleton to move forward.

[0066] When the automatic assembling complete set device for the rectangular steel bar skeleton is in use, it includes the following process steps: Step 1, a plurality of jacking mechanisms 5 rise simultaneously to transfer the stirrup angle on one side of the conveying guide rail to the jacking mechanisms 5, and the stirrup clamp 3 is temporarily supported by the jacking mechanisms 5. Step 2, a plurality of longitudinal bar supporting units 2 move along the conveying guide rail so that the longitudinal bar supporting units 2 are located outside the stirrup clamp 3; when the longitudinal bar supporting units 2 encounter the jacking mechanisms 5, the jacking mechanisms 5 descend to facilitate the passage of the longitudinal bar supporting units 2; after the plurality of longitudinal bar supporting units 2 move into place, the plurality of longitudinal bar supporting units 2 are evenly distributed along the extending direction of the stirrup clamp 3, so as to be more convenient for the longitudinal bar supporting units 2 to support the longitudinal bars more evenly subsequently. Step 3, adjust the relative positions of the bottom frame 21, the top frame 24, the left frame 22 and the right frame 23 so that the positions of the bottom frame 21, the top frame 24, the left frame 22 and the right frame 23 can be adapted to the stirrup size. Step 4, control a plurality of jacking mechanisms 5 to descend simultaneously so that the stirrup clamp 3 falls on the bottom base plate 211, and finely adjust the positions of the bottom base plate 211, the top base plate 241, the left base plate 221 and the right base plate 231 relative to the stirrup. At the same time, adjust the spacing of the V-shaped folding link 28 assemblies on the bottom base plate 211, the top base plate 241, the left base plate 221 and the right base plate 231 so that the guide wheels 25 on the bottom base plate 211, the top base plate 241, the left base plate 221 and the right base plate 231 can correspond to the positions where the longitudinal bars need to be installed on the stirrup. Step 5, the straightening base plate 42 in the straightening mechanism 4 descends, and control the relative movement of the left clamping block 46 and the right clamping block 47 to clamp the top end of the stirrup, so that the stirrup is kept in a vertical state; in this embodiment, since the stirrup mesh is large, by arranging the straightening mechanism 4 to clamp and straighten the top end of the stirrup, the stirrup will not be inclined and bent, thus ensuring the accurate alignment and accurate welding and fixing of the stirrup and the longitudinal bars.

[0067] Step 6: Insert the longitudinal bars into the guide wheels 25 of each longitudinal bar support unit 2 in sequence. After the longitudinal bars are in place, the upper pressing block 29 of the guide wheel 25 presses down on the longitudinal bars tightly. Step 7: First, weld the stirrups and longitudinal bars between the first longitudinal bar support unit 2 and the second longitudinal bar support unit 2. After the welding is completed, the centering mechanism 4 in the second longitudinal bar support unit 2 cancels the clamping of the stirrups and moves upward. At the same time, the bottom substrate 211, top substrate 241, left substrate 221, and right substrate 231 on the second longitudinal bar support unit 2 all drive their respective guide wheels 25 to move outward from the stirrups, so that the guide wheels 25 exit the range of the stirrups. Step 8: Keep the second longitudinal bar support unit 2 unchanged. The remaining longitudinal bar support units 2 drive the stirrup fixture 3 to move forward by the length of a centering fixture. Then, the centering substrate 42 in the centering mechanism 4 of the second longitudinal bar support unit 2 descends, controlling the relative movement of the left clamping block 46 and the right clamping block 47 to clamp the top end of the stirrup. Then, precisely weld and connect the stirrups and longitudinal bars within the clamping range of the centering mechanism 4 in the second longitudinal bar support unit 2. Step 9: Repeat Step 8 until all the stirrups and longitudinal bars are welded and connected. When the longitudinal bar support unit 2 behind the second longitudinal bar support unit 2 moves to interfere with it, the centering mechanism 4 in the interfering longitudinal bar support unit 2 cancels the clamping of the stirrups and moves upward. At the same time, the bottom substrate 211, top substrate 241, left substrate 221, and right substrate 231 on the longitudinal bar support unit 2 drive their respective guide wheels 25 to move outward from the stirrups, so that the guide wheels 25 exit the range of the stirrups.
