The two limiting plates 31 are respectively provided with positioning bosses 3111 on the sides of the two main side plates 11. The two limiting plates 31 can move away from or approach each other so that the positioning bosses 3111 on the two limiting plates 31 can be respectively inserted into or removed from the through holes 111 on the two main side plates 11. When using the boom oil pipe positioning block assembly tooling, the two limit plates 31 are close to each other so that the positioning bosses 3111 on the two limit plates 31 can be disengaged from the through holes 111 on the two main side plates 11, so that the main frame body 1 can be placed between the two hinged plates 101; then the two limit plates 31 are moved away from each other so that the positioning bosses 3111 on the two limit plates 31 are respectively inserted into the through holes 111 on the two main side plates 11, and are respectively plugged into the hinge holes 1011 on the two hinged plates 101, so that the main frame body 1 is limited between the two hinged plates 101, the positioning seat 2 can abut against the positioning inclined surfaces of the two hinged plates 101, and the positioning block 200 is positioned by the positioning seat 2, so that the positioning block 200 can be accurately welded to the corresponding hinged plate 101.

[0038] The boom oil pipe positioning block assembly tooling can be limited between the two hinged plates 101, and is inserted into the corresponding through hole 111 and the hinge hole 1011 through the positioning boss 3111, and then the positioning seat 2 is abutted against the positioning inclined surfaces of the two hinged plates 101 to limit the position of the positioning seat 2. The positioning block 200 is set on the positioning seat 2 for positioning to ensure the accurate position of the positioning block 200. Finally, the positioning block 200 is welded to the corresponding hinged plate 101 by welding.

This structure makes the overall structure more solid and the position more accurate.

[0049] The positioning seat 2 includes a vertical positioning plate 21 and positioning components connected to both ends of the vertical positioning plate 21 along a first direction. The vertical positioning plate 21 can abut against the positioning inclined surfaces of the two hinge plates 101, and the two positioning blocks 200 can be respectively limited on the two positioning components.

[0050] In this embodiment, the positioning block 200 is T-shaped, and includes a horizontal block and a vertical block connected perpendicularly to each other, and the vertical block is used to be welded to the outer side of the corresponding hinge plate 101.
