Abstract

The invention discloses a blind cavity structure interference assembly rotor cold assembly elastic guide device for assembly. The blind cavity structure interference assembly rotor cold assembly elastic guide device is characterized in that a guide shaft is a main body structure part and is of a cavity tubular structure, the right end of the guide shaft is of a large diameter and is provided witha step, the large diameter of the guide shaft is matched with the inner control large diameter of the shaft end of a low-pressure turbine, three radial fixing holes are formed in the guide shaft, a stop pin is welded to the edge of each hole, and the left end is of a conical guide structure. According to the invention, a screw rod is screwed inwards through a handle, a large compression spring iscompressed by pressing a core shaft to move towards the inner side, and the core shaft is separated from a stop pin when moving inwards in a rotating mode and retracts inwards into a radial fixing hole in the large end of a guide shaft under the elastic action of a compression spring, after a guide device is assembled to a wall groove in the end of a low-pressure turbine shaft, the screw rod is screwed out outwards through the handle, the stop pin moves outwards to extend out of the outer diameter surface of the large end of a guide pin shaft till the outer diameter surface is fixedly clamped,a low-pressure turbine rotor is assembled, the handle is assembled into a screw rod hole after assembly, and then the screw rod is screwed into and separated from the guide device inwards through thehandle.

[0020] Such as Figure 1-4 As shown, the technical solution is started from the low pressure turbine rotor shaft end structure and the internal structure of the whole machine core, and the inner hole column surface is used as radial positioning, and the inner hole card tank is used as an axial positioning, double spring stop Moving-pin switching scheme, making the boot device in rapid assembly, firm fixing, assembly guidance, and rapid decomposition process.

[0021] Assembly blind cavity structure over-profit fitting rotor cold elastic guiding device, including handle 1, screw 2, stop pin 3, hexagonal cylindrical head screw 4, mandrel 5, guide shaft 6, unpacking 7, small compression bomb篑 8, cover 9, large compression spring 10;

[0022] The guide shaft 6 is a main body structural component, a cavity tubular structure, the right end is a larger diameter and a step, and its large diameter is a large-diameter coordinated coordination of the low pressure turbine end 11, there is 3 radial fixing holes thereon. , The bore is welded 1 stop 3, the left end is a tapered guiding structure;

[0023] The mandrel shaft 5 is mounted in the inner cavity of the guide shaft 6, which can be moved in the guide shaft 6, and the right end is a tapered structure, and the right end is mounted with a large compression spring 10;

[0024] The cover plate is tightened with a large compression spring 10 and the left hex cylindrical head screw 4 is tightened by the left hex cylindrical head screw 4, and the hexagonal cylindrical head screw 4 is 6 pieces, and the cover 9 presses the large compression spring 10;

[0025] The radiocial direction is mounted in the radial fixing hole of the first end of the guide shaft 6, which can be radially movable, and the inside of the upper side is in the right end tapered structure, and the unpacking 7 The small compression spring 8 is mounted, and the receiving pin 7 can be worn by the radially fixed hole in the large-end cavity in the right end of the guide shaft 6;

[0026] The left end of the screw 2 is inserted into the guide shaft 6 inserted by a threaded structure, and the rotary shaft 5 is held at the right end of the screw 2;

[0027] The handle 1 is a pressing device of the rotary screw 2, detachable.

[0028] The mounting guide shaft 5 is mounted in the inner cavity of the mounting guide as an assembly fixed shaft end and the decomposition, which can be moved in the guide shaft 6, and the right end is a tapered structure for driving the guide shaft fixed connector, and the right end is installed. The compression spring 10 provides a guide shaft moving elastic force.

[0029] 3 pieces in the unpacking 7, mounted in the radially fixed hole in the upper right end of the guide shaft 6, can be moved radially, the inner side large end, the mandrel 5 right tapered structure, close to the guide shaft 6 position When the small compression spring 8 is mounted, when the retaining 7 compresses the small compression spring 8, the reception pin 7 can be passed through the radially fixed hole in the large-end cavity in the right end of the guide shaft 6, and the low pressure turbine end 11 can be copied after passing out. Fixed in the interior of the end.

[0030] Operation process of assembly of blind cavity structures over-profile fitting rotor reflex elastic guiding device:

[0031] 1) Before the guidance device is used, the handle 1 is mounted to the screw 2 in the screw 2, and the screw 2 is rotated inward, the screw 2 is moved inward, and the screw 2 is moved toward the inner side, and the mandrel 5 is moved, and the large compression spring is compressed. 10, the mandrel 5 and the receiving pin 7 contact surface are tapered, and the mandrel 5 is disengaged from the unblocking 7, and the retaining pin 7 is elastically elastically populated inward, and the outer end position of the unfaming 7 is positioned. The pin zone into the leading shaft 6 is radially fixed;

[0032] 2) When the reception pin is all incorporated into the hole, the guiding device is assembled to the low pressure turbine end 11. After the guiding device is assembled, the stop pin 3 is attached to the low pressure turbine end 11 wall tank to prevent circumference to rotate;

[0033] 3) Use the handle 1 to remove the screw 2 outward, and the screw 2 is disengaged when the screw 2 is disengaged, and the mandrel 5 right ends large compression spring 10 release the elastic push the mandrel 5 to the left, the mandrel 5 right tapered surface moves left moving Pushing the backswing 7 moves outward, the reception pin 7 compresses the small compression spring, and the returning pin 7 moves outwardly projects the outermost outer diameter surface of the guide pin 6, and the fixed hole is inserted into the low pressure turbine end 11 casing groove. Fixed tension, divide the handle 1;

[0034] 4) Cooling the low pressure turbine rotor shaft end, the low pressure turbine rotor of the guide device is assembled to the core machine rotor blind cavity by the guiding device, avoiding the plurality of graphite seals and disk parts in the cavity, and the shaft with the fan The hole is connected, and the fan axis is formed in the face;

[0035] 5) After the assembly is completed, the handle 1 to the screw 2 is assembled, and again use the handle 1 to rotate the screw 2 inward, the screw 2 is moved toward the inner side, the mandrel 5 is moved, and the large compression spring 10, core When the shaft 5 is moved to the inner rotation pin 7, the retaining pin 7 is elastically elastically elastic, and the outer end position pin of the unfaming switch 7 is subjected to the large end of the guide shaft 6. The low pressure turbine end 11 card tank, the guiding device is a non-fastened state;

[0036] 6) After separating the boot device, complete the device assembly work.
