[0017] Example

[0018] See also Figure 1 to Figure 2As shown, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model.

The change or adjustment of their relative relationship, without substantially changing the technical content, should also be regarded as the scope of the implementation of the utility model.

[0019] The pin shaft welding tool for aerial work vehicles with a rotating function in this embodiment includes a tool bracket 1, a tightening mechanism 2 and a rotating mechanism 3. The tool bracket 1 includes a tool bottom plate 11, a tool top plate 12 and a tool guide rod 13. The tool bottom plate 11 and the tool top plate 12 are respectively fixed at both ends of the tool guide rod 13. The tightening mechanism 2 is installed on the tool bottom plate 11, and the rotating mechanism 3 is installed on the tool top plate 12, and the tightening mechanism 2 cooperates with the rotating mechanism 3.

[0020] The tightening mechanism 2 in this embodiment includes a tightening cylinder 21, a tightening pressure plate 22, a tightening sleeve 23, a tightening limit seat 24 and a tightening rotating seat 25. The tightening cylinder 21 is installed on the tooling base plate 11, the tightening pressure plate 22 is connected to the piston rod of the tightening cylinder 21, the tightening sleeve 23 and the tightening limit seat 24 are both fixed on the tightening pressure plate 22, the tightening sleeve 23 is mounted on the tooling guide rod 13, and the tightening rotating seat 25 is rotatably installed on the tightening limit seat 24.

[0021] The rotating mechanism 3 in this embodiment includes a rotating motor 31, a rotating sleeve 32, a rotating limit plate 33, a rotating limit ring 34, a rotating buffer spring 35 and a telescopic socket 36. The rotating motor 31 is installed on the tooling top plate 12. The motor shaft of the rotating motor 31 is connected to the rotating sleeve 32. The two ends of the rotating sleeve 32 are each fixed to a rotating limit plate 33. The rotating sleeve 32 is rotatably installed on the tooling top plate 12.

[0022] The rotation limit ring 34 and the rotation buffer spring 35 in this embodiment are sleeved on the outside of the rotation sleeve 32, and the two ends of the rotation buffer spring 35 are respectively abutted against the rotation limit ring 34 and the rotation limit plate 33.

[0023] Specifically, when the aerial work vehicle pin shaft welding tool with a rotating function is in use, the pin plate is placed on one end of the shaft, and the tightening cylinder 21 drives the tightening pressure plate 22 to lift it up, so that the tightening rotating seat 25 contacts the other end of the shaft, and at the same time, the pin plate contacts the rotation limit plate 33. Through the set gap 37, the rotation limit plate 33 will move slightly upward during tightening, and the rotation limit plate 33 will rebound and tighten through the rotating buffer spring 35. The rotation limit plate 33 is driven to rotate by the rotating motor 31, and then the pin plate and the shaft can drive the tightening rotating seat 25 to rotate synchronously, so that the comprehensive welding of the pin plate and the shaft can be realized.
