Description
Technical field
The utility model belongs to engine maintenance technical field, and in particular to a kind of hand CFM56 engine high pressures turn
Sub- rotary tooling.
Background technology
CFM56-3, CFM56-5B and CFM56-7B engine are the aero-engines of CFMI global groups production, extensively should
Boeing and Airbus Aircraft for current civil aviation passenger transport.This engine is when entering factory's overhaul, it is often necessary to do hole spy
Check and concentricity inspection.It is accomplished by rotating the rotor of engine this when, allows detection device to detect per a piece of rotor leaf
The situation of piece.And generally can be according to workshop repair manual, using electronic frock, and need to be arranged on Accessory Gear Box
On, high pressure rotor axial-rotation is driven with 40 teeth in gear-box or 47 gears, to reach the mesh for checking every blade one by one
's.
Need to pull down Accessory Gear Box during yet with engine overhaul and repair, the repair cycle is longer, generally requires
Treat 20-30 days, and the inspection need of work of many high pressure rotors is carried out during this period, but be due to that gear-box is not reinstalled and started
Machine, causes no impetus to rotate high pressure rotor, completes corresponding inspection work, such as hole is visited and concentricity is beated and checked
Deng all inspections can only all be returned after Accessory Gear Box reinstalls engine and could completed.
If one Accessory Gear Box of purchase is used as frock, need to spend million RMB, and traditional electronic work
Dress can only provide the at the uniform velocity rotation of single direction, it is impossible to slowly or accelerate high pressure rotor rotation speed according to the need for inspection
Degree, thus need to develop at this stage it is a kind of do not need gear-box to rotate the frock of high pressure rotor yet, and the frock energy according to
The demand of examiner controls rotating speed and the direction of rotation of high pressure rotor at any time, is started with facilitating the maintenance to engine, and saving
Machine repair cycle and company's manpower and material cost.
Utility model content
The purpose of this utility model is that provides a kind of hand CFM56 engine high pressures to solve the above problems
Rotor rotary tooling.
The utility model is achieved through the following technical solutions above-mentioned purpose：
Hand CFM56 engine high pressure rotor rotary toolings, including connector, platform, rotary head, the connector bag
The cylinder ring that middle part is set is included, the cylinder ring is internally provided with spline, and the spline is arranged on CFM56 engine radial drives
In axle, the connector is connected with one end of the platform, and the other end of the platform is connected with the first end of the rotary head,
The axle center of the cylinder ring and the rotary head is on same straight line, and the other end of the rotary head is provided with driving hole.
Further, using welding between the cylinder ring and the rotary head.
Further, the driving hole set on the rotary head is regular polygon.
Preferably, the driving hole set on the rotary head is square.
The beneficial effects of the utility model are：
During utility model works, loaded with the spline of frock in engine radial drive axle, be then connected to spanner
It is with frock spline that radial drive axle is stuck in the driving hole of frock, allow the strength of hand to pass through frock spline and radial drive axle
After be communicated to high pressure rotor, then just can use hand ease rotation high pressure rotor, according to inspection the need for, can arbitrarily rotate
Son, and the speed of spinner velocity can control freely manually.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the second end structure schematic diagram of the present utility model.
In figure：1st, connector；2nd, spline；3rd, rotary head；4th, platform.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, hand CFM56 engine high pressures rotor rotary tooling, including connector 1, platform 4, turn
Dynamic first 3, connector 1 includes the cylinder ring that middle part is set, and cylinder ring is internally provided with spline 2, and spline 2 starts installed in CFM56
In machine radial drive axle, connector 1 is connected with one end of platform 4, and the other end of platform 4 is connected with the first end of rotary head 3, circle
The axle center of the band of column and rotary head 3 is on same straight line, and the other end of rotary head 3 is provided with driving hole.
Using welding between cylinder ring and rotary head 3.
The driving hole set on rotary head 3 is regular polygon.Preferably, what is set in the present embodiment on rotary head 3 pulls
Hand hole is square.
During utility model works, loaded with the spline 2 of frock in engine radial drive axle, be then connected to spanner
It is with frock spline 2 that radial drive axle is stuck in the driving hole of frock, allow the strength of hand to pass through frock spline 2 and radial drive
High pressure rotor is communicated to after axle, then just can use hand ease rotation high pressure rotor, according to inspection the need for, can arbitrarily rotate turn
Son, and the speed of spinner velocity can control freely manually.
Of the present utility model to substitute the function of Accessory Gear Box and Transfer Gearbox, handmade rotary high pressure rotor is with complete
Into items inspection.Connector 1, which is substantially in the middle of the annex gear in a Geju City, gear, in the frock main body the intact groove of spline 2,
Then in one platform 4 of gear front welding, platform 4 reconnects one driving hole of welding in the middle of rotary head 3, rotary head 3.
The utility model is made using end-of-life engine material, is not almost spent in cost, and because is to start
The part of machine in itself is made, frock size very standard, and matching is strong, will not damage engine part, and can be
Used on various CFM56 types, tri- kinds of types of CFM56-3, CFM56-5, CFM56-7 can be used, and in use
The need for can be according to inspection, arbitrarily clockwise, rotor be rotated counterclockwise, the speed of speed can also be controlled conveniently.Often repair
One engine just saves nearly million material cost and the maintenance time cost of 20 days or so for company.
General principle of the present utility model, principal character and advantage has been shown and described above.The technical staff of the industry
