The tooling of mounting base flaring.
Background technique
Certain aero-engine supports casing, needs to install two sealing devices on the cylinder of support casing, such as Fig. 1 institute
Show, 10 be sealing device, and 20 be mounting base, has 40 ° of groove in end, needs for sealing device to be flared, be pressed on mounting base
On, guarantee that sealing device is connected with mounting base, guarantees that sealing device does not fall off from main body.Usually flaring is using circular impact
Mode is processed, but the mounting base in the part with main body is connect using argon arc welding mode, and impact will lead to part
Weld seam cracks；It can also be allowed to be adjacent to mounting base using flaring face is beaten by hand, but this method hammer and installation seated connection
Contacting surface is smaller, and sealing device and being bonded for mounting base are bad after percussion, is easy to produce and falls off, is unable to reach matching requirements.In addition,
Flaring face at the mounting device is small-sized, such as so that sealing device is badly deformed with mounting base and close using conventional percussion mode
It cuts to be bonded and needs repeatedly to tap and test repeatedly, working hour length, difficulty are big, and yield rate is extremely low.
Summary of the invention
It is flared in order to solve the above technical problems, the present invention provides one kind for aero-engine Thin-Wall Outer Casing sealing device
Tooling.
The present invention is achieved by the following technical programs.
A kind of tooling for the flaring of aero-engine Thin-Wall Outer Casing sealing device provided by the invention, including sealing dress
It sets, mounting base, pressed seat, be flared part and clamping nut, wherein pressed seat is indent tubular structure；Flaring part is hammer body knot
Structure, upper end are thin axis body, and outside is equipped with external screw thread corresponding with the internal screw thread of clamping nut, and lower end is rotary table, and side is equipped with straight
The conical surface that diameter is up gradually reduced by lower part；In use, the installation end of sealing device is placed in mounting base, pressed seat is set to close
On seal apparatus, the upper end for being flared part sequentially passes through mounting base, sealing device and pressed seat from bottom, and matches with clamping nut
It tightens, presses closer the conical surface for being flared part lower end on the medial surface of mounting base.
It further, further include protective case, the protection is placed between sealing device and pressed seat.
Further, the conical degree of conical surface of the flaring part lower end is 40 °.
It further, further include crowbar, the lower end of the flaring part is equipped with lateral through-hole, and crowbar is installed on across through-hole
It is flared part lower end.
Further, the indent drum diameter size of the pressed seat and the outer diameter of sealing device are in the same size.
Further, the protective case is indent tubular structure, the outer diameter of indent drum diameter size and sealing device
It is in the same size.
Further, the outer diameter size of the protective case and pressed seat internal diameter is in the same size.
The beneficial effects of the present invention are: by the present invention in that pressing closer sealing device with the flaring part for being provided with the lateral conical surface
With mounting base, and compression operation is carried out in such a way that screw thread is tightened in assembly, successfully avoid traditional impact type and expand
Mouth generates the defect that impact causes weld seam to crack to weld seam, and the sealing device expanded using the flaring tool is solid and reliable,
In addition, the present invention protects sealing device using protective case, sealing device is made to avoid being weighed wounded during assembly, this
Tool structure is simple, easy to implement, can it is a variety of carry out flaring assembly occasions carry out using.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in figures 1 to 6, a kind of tooling for the flaring of aero-engine Thin-Wall Outer Casing sealing device, including sealing dress
It sets, mounting base, pressed seat, be flared part and clamping nut, wherein pressed seat is indent tubular structure；Flaring part is hammer body knot
Structure, upper end are thin axis body, and outside is equipped with external screw thread corresponding with the internal screw thread of clamping nut, and lower end is rotary table, and side is equipped with straight
The conical surface that diameter is up gradually reduced by lower part；In use, the installation end of sealing device is placed in mounting base, pressed seat is set to close
On seal apparatus, the upper end for being flared part sequentially passes through mounting base, sealing device and pressed seat from bottom, and matches with clamping nut
It tightens, presses closer the conical surface for being flared part lower end on the medial surface of mounting base.
It further, further include protective case, the protection is placed between sealing device and pressed seat.
Further, the conical degree of conical surface of the flaring part lower end is 40 °.
