[0018] The present utility model will be further described below by way of examples, but the present utility model is not limited to the scope of the described examples.

[0019] Example 1

[0020] As Figures 1-3As shown, this embodiment provides a tool-assisted basket bolt. The basket bolt includes: a screw rod 1, a wrench 2, a first adjustment piece 3, a second adjustment piece 4 and a thread 5. The screw rod 1 is provided with a screw rod hole, and a wrench 2 is vertically inserted into the screw rod hole. The wrench 2 is used to adjust the screw rod 1; the first adjustment piece 3 and the second adjustment piece 4 are respectively sleeved at both ends of the screw rod 1. The first adjustment piece 3 is in contact with the outer ring plate wall of the outer ring plate of the rear guide vane assembly, and the second adjustment piece 4 is in contact with the inner ring plate of the rear guide vane assembly; and threads 5 are provided at both ends of the screw rod 1. Among them, a gasket is provided on the first connecting piece 32, and the gasket is fixed to the first connecting piece 32 by bolts. The first connecting piece 32 of the basket bolt of this embodiment is in contact with the outer ring plate wall of the outer ring plate, the wrench 2 is inserted into the screw rod hole of the screw rod 1, and the wrench 2 is rotated to drive the screw rod 1 to rotate. As the screw rod 1 rotates, the first adjusting blade 3 and the second adjusting blade 4 on both sides of the screw rod 1 are further expanded outward until the second connecting piece 42 can support the inner ring plate. After confirming the relative positions of the inner and outer ring plates, use the wrench 2 to fine-tune the screw rod 1 one by one to ensure that the relative positions of the inner and outer ring plates are correct when each tool-assisted basket bolt is installed.

[0021] In this embodiment, the first adjustment piece 3 includes a first moving block 31 and a first connecting piece 32, one end of the first moving block 31 is fixed to the first connecting piece 32, and the other end is sleeved on the screw rod 1. Among them, the first moving block 31 is sleeved on the end of the screw rod 1 and is provided with a first circular nut 33, and the first circular nut 33 is screwed with the thread 5. By inserting the wrench 2 into the screw hole of the screw rod 1 and rotating the wrench 2, the first moving block 31 can be driven to move on the screw rod 1 through the thread 5 and the first circular nut 33.

[0022] In this embodiment, the second adjustment piece 4 includes a second moving block 41 and a second connecting piece 42, one end of the second moving block 41 is fixed to the second connecting piece 42, and the other end is sleeved on the screw rod 1. Among them, the second moving block 41 is sleeved on one end of the screw rod 1 and is provided with a second circular nut 43, and the second circular nut 43 is screwed with the thread 5. By inserting the wrench 2 into the screw hole of the screw rod 1 and rotating the wrench 2, the second moving block 41 can be driven to move on the screw rod 1 through the thread 5 and the second circular nut 43, thereby driving the second connecting piece 42 to move until it is close to the inner ring plate and supports the inner ring plate.

[0023] This embodiment provides a tooling-assisted basket bolt. The basket bolt is used to assist in the welding of the inner and outer ring plates of the rear guide vane assembly, and the first adjustment piece and the second adjustment piece at both ends of the screw are adjusted to limit the relative position displacement of the inner and outer ring plates and support the stress generated by the deformation during the welding of the rear guide vane, thereby ensuring the concentricity of the inner and outer ring plates of the rear guide vane assembly and improving the welding effect.

[0024] The working principle of the present utility model is as follows: calibrate the positions of the inner and outer ring plates of the rear guide vane assembly on the welding platform until the inner and outer ring plates are concentric, and then weld the guide vanes; install the turnbuckle of the tooling auxiliary of the present utility model at the interval of each rear guide vane, install a gasket on the first connecting piece 32 of the turnbuckle and fix it with a bolt, and then abut the first connecting piece 32 against the outer wall of the outer ring plate; insert the wrench 2 into the screw hole of the screw rod 1 and rotate the wrench 2 to drive the screw rod 1 to rotate. Under the rotation of the screw rod 1, the first moving block 31 and the second moving block 41 on both sides of the screw rod 1 are further expanded outward through the thread 5 until the second connecting piece 42 can abut against the inner ring plate. After confirming the relative positions of the inner and outer ring plates, use the wrench 2 to finely adjust the screw rod 1 one by one to ensure that the relative positions of the inner and outer ring plates are correctly fixed by each tooling auxiliary turnbuckle installed. After each rear guide vane is welded to the inner and outer ring plates and the natural cooling stress is released, remove the installed tooling auxiliary turnbuckle.
