Abstract
The invention discloses a single-disk reaming method of a high-pressure rotor labyrinth disk. A labyrinth disk is independently fixed on a clamp to ensure that the single labyrinth disk carries out single disk reaming when axial deformation is coincident to the assembly state; the labyrinth disk to be processed is independently assembled on the clamp and is tightly pressed by process bolts so as to ensure that the axial deformation of the labyrinth disk and the assembly state are coincident; the clamp in which the labyrinth disk is arranged is installed on a rock arm drilling machine, and then the process bolt on the labyrinth disk is removed every other process bolt; according to the size required to be processed, a proper cutter is chosen, installed on the drilling machine and fixed after centering; rough reaming is carried out on the loosened bolt hole of the labyrinth disk, and then fine reaming is carried out; manual feed is adopted for processing; the cutter rotation speed is 70-80 r/min; the process bolts are used for tightly pressing processed holes, other process blots which do not process holes are loosened, and the bolt holes which are not processed are processed; and a dial test indicator and a ring gauge are adopted for aperture measurement detection.
Description
Technical field
The present invention relates to field of machining, be specifically related to a kind of single-disk reaming method of high-pressure rotor labyrinth disk.
Background technology
The position degree of certain overhaul machine replacing new product powder metallurgy labyrinth and former high-pressure compressor rotor assembly bolt hole is inconsistent, and indivedual rotor component bolt hole position offsets are bigger, will carry out high pressure rotor combination fraising when changing the powder metallurgy labyrinth.The combination fraising needs labyrinth and other dish are reamed together, and this kind process has following problem: along with the engine overhaul number of times increases, existing part high life engine high pressure rotor bolt bore dia has reached Φ 10.9, Φ 11.And the diameter of bolt hole specification requirement maximum of high pressure rotor allows Φ 11.1, and each high pressure rotor combination fraising needs to strengthen 0.2～0.3mm and could satisfy specification requirement, and in this case, carrying out high pressure rotor combination fraising just has great risk; In case unsuccessful, whole high pressure rotor faces and scraps, and the high pressure rotor complex structure; The processing part is made up of 9 parts, and cutting depth is longer, adopts the combination fraising that the cutter temperature is raise and the generation distortion; Cause error, simultaneously, the aperture size required precision is higher; Situation such as the combination fraising causes dimension overproof easily, and ovality is undesirable, so difficulty of processing is bigger.The combination fraising needs the stay bolt bottom locking nut on each dish is decomposed complex operation.
Summary of the invention
To adopting the combination fraising that great risk is arranged to high pressure rotor in the prior art; In case it is unsuccessful; Whole high pressure rotor faces the shortcoming and defect of scrapping, and the invention provides a kind of single-disk reaming method of high-pressure rotor labyrinth disk, and the method can increase the number of times repaired of high pressure rotor; Boost productivity, reduce the cutter use cost.
The present invention adopts following technical scheme:
Single-disk reaming method of high-pressure rotor labyrinth disk is fixed on labyrinth separately on the anchor clamps, guarantees that the single-piece labyrinth carries out the single-deck fraising under axial deflection is consistent with confined state, and high-pressure rotor labyrinth single-deck fraising step is following:
1, labyrinth to be processed is assembled to separately on the anchor clamps, compresses, make the axial deflection of labyrinth consistent with confined state with bolt;
The anchor clamps that 2, labyrinth will be housed are installed on the radial drilling machine, and centering also compresses with bolt;
3, on labyrinth, whenever tear next bolt open at a distance from a bolt;
4, the suitable cutter of processing as required of size Selection also is installed on the drilling machine, and is fixing behind the centering;
5, open lathe, the bolt hole that labyrinth is unclamped slightly reams, and hand feed, cutter rotating speed 70～80r/min are adopted in thick fraising;
6, change finishing tool, fixing behind the centering, labyrinth is finish reamed the hole, finish ream the hole and adopt hand feed, cutter rotating speed 70～80r/min;
7, the hole after will processing with bolt compresses, and unclamps the bolt that all the other do not carry out machining hole;
8, repeating step 5,6 is processed all the other unprocessed holes;
9, carry out the inside diameter measurement check with dial test indicator and ring gauge;
Described anchor clamps integral body is cylindrical shape; The middle part has boss, has through hole at the middle part of boss, on boss through hole around be processed with the bolt hole; Around boss is annular groove; In annular groove, be processed with lightening hole, the upper surface of the table top of boss and the side of boss and annular groove outer is the locating surface of clamping labyrinth, is symmetrily processed with fixing hole in the side of anchor clamps.
Described cutter comprises cutter hub and cutter head, and tool tip material adopts carbide alloy, the diameter dimension 10.45mm～11.1mm of cutter head.
Beneficial effect of the present invention:
Single-disk reaming method of high-pressure rotor labyrinth disk of the present invention only reams to labyrinth, does not make an amendment for other dish of high pressure rotor, has therefore avoided the situation of the integral high pressure rotor being scrapped because other dish fraising is unsuccessful.Because the diameter of bolt hole specification requirement maximum of high pressure rotor allows Φ 11.1; Adopt the each labyrinth of changing of combination fraising all to need the high pressure rotor dish is reamed; Cause the diameter of bolt hole of high pressure rotor to reach maximum and scrap, and adopt the single-deck fraising, do not need other dish of high pressure rotor is reamed; Avoided having increased the maintenance access times of high pressure rotor owing to the excessive situation of scrapping of high pressure rotor bolt hole.The single-deck fraising adds cutting depth weak point in man-hour, can not take place to be out of shape owing to temperature is too high in the cutter process, causes machining accuracy situation not up to standard.The single-deck fraising has avoided combination processing to cause each part dimension overproof, the underproof situation of ovality.Adopt the method for single-deck fraising that labyrinth is reamed, labyrinth is compressed, under the environment of simulation assembling, process, make labyrinth more can meet the requirement of assembling, and need each dish not decomposed through anchor clamps and bolt, simple to operation.
The method has increased the number of times repaired of high pressure rotor, has reduced unnecessary waste, boosts productivity, and has reduced the cutter use cost simultaneously, and economic benefit is very considerable.
