[0061] like Figure 5-8 As shown, the boom 1 is divided into SUV long right boom, SUV long left boom, short right boom and short left boom. The structures of the SUV long right boom, SUV long left boom, short right boom and short left boom are the same, except that the length and bending radius of the round tube 13 in the SUV long right boom, SUV long left boom and short right boom and short left boom are different. The difference between the SUV long right boom and the SUV long left boom, short right boom and short left boom lies in whether the welding plate 14 is arranged on the right side or the left side of the round tube 13, and whether the welding tail plate 15 is installed positively or reversely with the round tube 13.

[0062] like Figure 5-8 As shown, the welding plate 14 in the long right boom and the short right boom of the SUV is set on the right side of the circular tube 13, and the welding tail plate 15 and the circular tube 13 are installed in reverse. The welding plate 14 in the long left boom and the short left boom of the SUV is set on the left side of the circular tube 13, and the welding tail plate 15 and the circular tube 13 are installed in the right direction.

[0063] Therefore, a manual positioning and pressing long boom welding tool is used for the SUV long right boom and the SUV long left boom, and a manual positioning and pressing short boom welding tool is used for the short right boom and the short left boom. The difference between the manual positioning and pressing long boom welding tool and the manual positioning and pressing short boom welding tool is that the base plate I-shaped support seat 32 in the base plate quick-change clamping and positioning assembly 3 has a different height to suit the larger bending angle of the round tube 13 and the welding rib 12. At the same time, the welding plate support clamping and positioning assembly 6 and the tail plate support clamping and positioning assembly 7 need to be appropriately adjusted in position according to the different lengths of the round tube 13.

[0064] like Figure 9 、 12As shown, in order to increase the applicability of the manual positioning and clamping boom welding fixture, the manual positioning and clamping long boom welding fixture and the manual positioning and clamping short boom welding fixture are combined to form a manual positioning and clamping comprehensive boom welding fixture, so that it only needs to replace the bottom plate quick-change clamping positioning component 3, the welding plate support clamping positioning component 6, and the tail plate support clamping positioning component 7 to realize the assembly of the SUV long right boom, SUV long left boom, short right boom, and short left boom. For the convenience of description, the quick-change clamping positioning components are divided into short quick-change clamping positioning components, long quick-change clamping positioning components, short quick-change clamping positioning components, long quick-change clamping positioning components. The only difference between the positioning components is the height of the base plate I-beam support seat 32. The welding plate support clamping positioning component 6 is divided into a short welding plate support clamping positioning component 10 and a long welding plate support clamping positioning component 101. The only difference between the short welding plate support clamping positioning component 10 and the long welding plate support clamping positioning component 101 is the installation position. The tail plate support clamping positioning component 7 is divided into a short welding plate support clamping positioning component 10 and a long welding plate support clamping positioning component 101. The only difference between the short welding plate support clamping positioning component 10 and the long welding plate support clamping positioning component 101 is the installation position.

[0065] like Figure 9 、 12 As shown, according to the above manual positioning and pressing integrated boom welding fixture, it includes: frame body 2, short base plate quick-change clamping and positioning assembly 8, long base plate quick-change clamping and positioning assembly 9, rib plate support and positioning assembly 4, round tube clamping and positioning assembly 5, short welding plate support and clamping and positioning assembly 10, long welding plate support and clamping and positioning assembly 101, short tail plate support and clamping and positioning assembly 102, long tail plate support and clamping and positioning assembly 103, the rib plate support and positioning assembly 4, round tube clamping and positioning assembly 5, short welding plate support and clamping and positioning assembly Part 10 and the long tail plate support clamping and positioning assembly 103 are fixed on the frame body 2, their positions remain unchanged and cannot be replaced. The short base plate quick-change clamping and positioning assembly 8 or the long base plate quick-change clamping and positioning assembly 9 are selected as needed and installed on the frame body 2 on one side of the rib support and positioning assembly 4. The long welding plate support clamping and positioning assembly 101 and the short tail plate support clamping and positioning assembly 102 are selected as needed and installed on the frame body 2 between the short welding plate support clamping and positioning assembly 10 and the long tail plate support clamping and positioning assembly 103.

[0066] like Figure 9 、 10As shown in , 11, when the long boom 1 is assembled, that is, when the SUV long right boom and the SUV long left boom are assembled, the manual positioning and pressing integrated boom welding tooling includes: a frame body 2, a long bottom plate quick-change clamping and positioning assembly 9, a rib support positioning assembly 4, a round tube clamping and positioning assembly 5, a short welding plate support clamping and positioning assembly 10, a long welding plate support clamping and positioning assembly 101, and a long tail plate support clamping and positioning assembly 103. The long bottom plate quick-change clamping and positioning assembly 9, the rib support positioning assembly 4, the round tube clamping and positioning assembly 5, the short welding plate support clamping and positioning assembly 10, the long welding plate support clamping and positioning assembly 101, and the long tail plate support clamping and positioning assembly 103 are fixed on the frame body 2, wherein the short welding plate support clamping and positioning assembly 10 does not participate in the work.

[0067] like Figure 12 、 13 As shown in 14, when the short boom 1 is assembled, that is, when the short right boom and the short left boom are assembled, the manual positioning and pressing integrated boom welding tooling includes: a frame body 2, a short bottom plate quick-change clamping positioning assembly 8, a rib support positioning assembly 4, a round tube clamping positioning assembly 5, a short welding plate support clamping positioning assembly 10, a short tail plate support clamping positioning assembly 102, and a long tail plate support clamping positioning assembly 103, wherein: the frame body 2, the short bottom plate quick-change clamping positioning assembly 8, the rib support positioning assembly 4, the round tube clamping positioning assembly 5, the short welding plate support clamping positioning assembly 10, the short tail plate support clamping positioning assembly 102, and the long tail plate support clamping positioning assembly 103 are fixed on the frame body 2, and the long tail plate support clamping positioning assembly 103 participates in the work.

[0068] like Figure 18 As shown in the figure, (1) the welding plate 14 is installed on the right side and the welding tail plate 15 is installed in reverse, which is suitable for the installation of the long right boom and the short right boom of the SUV. (2) the welding plate 14 is installed on the left side and the welding tail plate 15 is installed in the normal way, which is suitable for the installation of the long left boom and the short left boom of the SUV.
