The tower crane round main rotating rod standard section (round standard section) has a smaller wind resistance coefficient and more uniform stress distribution than the square main rotating rod standard section when working at high altitude, and has gradually become the mainstream of the future market. However, since the round standard section is mainly welded by cylindrical main rotating rods, cylindrical straight webs, cylindrical diagonal webs, cylindrical handrails, etc., there are a large number of saddle-shaped intersection lines when the main rotating rod, straight webs, diagonal webs, handrails, etc. are assembled, and the existing square standard section welding robot production line cannot realize the automatic welding of round standard sections. Therefore, it is necessary to propose a welding robot production line suitable for automatic welding of round standard sections.

At this time, it is only necessary to adjust the notch size of the second straight web bar shape-changing positioning groove 3113 located below the straight web bar 1001 to meet the needs of different types of straight web bars 1001. At this time, the structure of the second straight web bar shape-changing positioning mechanism 311 can be simplified, and only the size of the slot of the second straight web bar shape-changing positioning slot 3113 can be changed. For example, there are two types of straight web bars 1001, which can be used as follows: Fig.14 The second straight web bar shape-changing positioning groove 3113 shown in the figure can be composed of two arc segments with different radii. If necessary, the height can be adjusted by the tenth driving device 3112.

[0074] like Fig.15 As shown, a railing shape-changing positioning mechanism 312 for positioning the middle of railings 1003 of different models is provided between the railing positioning assembly 307 and the diagonal web member 1002; the railing shape-changing positioning mechanism 312 includes a fourth connecting plate 3121, and a railing shape-changing positioning groove 3122 for matching railings 1003 of different models is provided on the fourth connecting plate 3121, and the inner notch of the railing shape-changing positioning groove 3122 includes multiple arc segments with different radii. The above-mentioned railing shape-changing positioning groove 3122 can also adopt a structural form similar to the second straight web member shape-changing positioning groove 3113.

[0075] The assembly tool of this embodiment is mainly composed of a tooling table 301 and a positioning mechanism. The positioning components are designed by using the saddle-shaped assembly relationship between the diagonal brace 1002, the straight brace 1001, the bent plate 1004 and the main chord 1000, as well as the positioning layout of the overall structure. The relative relationship between the workpieces is achieved through the cooperation of the driving device (such as a cylinder + guide rail) and the profiling block / fixed block. The usage method can be as follows: the handling robot first uses the loose parts gripper loading tooling (the gripper loading tooling can be designed with a standard quick-change interface) to clamp the straight brace 1001, diagonal brace 1002, bent plate 1004, railing 1003 and other workpieces from the material trailer and put them into the overall assembly tooling. Overall loading and positioning process: the position of the diagonal web member-straight web member-diagonal web member positioning assembly 304 is fixed, the robot puts the two diagonal web members 1002 in place through the loading tooling, the diagonal web member-bent plate positioning assembly 302 pushes out and clamps the diagonal web member 1002, and the diagonal web member-straight web member positioning assembly 303 pushes out and clamps the diagonal web member 1002, so that the positioning of the two diagonal web members 1002 can be achieved, and the positions of the diagonal web member-bent plate positioning assembly 302 and the diagonal web member-straight web member positioning assembly 303 are fixed. The robot puts the two straight web members 1001 in place through the loading tooling, and the straight web member positioning assembly 306 extends out and clamps the straight web member 1001, so that the positioning of the two straight web members 1001 can be achieved, and the position of the straight web member positioning assembly 306 is fixed. The robot puts the two railings 1003 in place through the loading tooling, and the railing positioning assembly 307 pushes out and clamps the railings 1003, so that the positioning of the two railings 1003 can be achieved, and the position of the railing positioning assembly 307 is fixed at this time. The robot puts the bent plate 1004 in place through the loading tooling, and the bent plate positioning assembly 305 pushes out and clamps the bent plate 1004, so that the positioning of the bent plate 1004 can be achieved, and the position of the bent plate positioning assembly 305 is fixed at this time. Through the above process, accurate and rapid positioning of each work can be achieved.

[0076] During use, for different types of products, the first profiling block 3021, the second profiling block 3031 and the third profiling block 3041 can replace sub-blocks to adapt to different types of products. At the same time, the bent plate shape-changing positioning mechanism 308, the oblique web bar shape-changing positioning mechanism 309, the first straight web bar shape-changing positioning mechanism 310, the second straight web bar shape-changing positioning mechanism 311 and the railing shape-changing positioning mechanism 312 also replace components or adjust positions respectively, so as to be suitable for positioning work of different types of products.

[0077] The assembly tooling of the tower crane standard section component workpiece of the utility model can realize high-precision assembly and positioning of the straight web member 1001, the diagonal web member 1002, the handrail 1003, and the bent plate 1004, and adopts the matching relationship with the main chord 1000 for positioning, with high positioning accuracy and small error. While improving the positioning accuracy, it can also reduce manual operations, alleviate manual assembly and transportation.
