Description
Technical field
The present invention relates to aero-engine spare parts to fabricate field, and in particular to one kind is used for the split metal plate weldering type of thin-walled
The outer tooling device for containing casing installation side processing.
Background technique
Containing casing (hereinafter referred to as casing) outside certain model aero-engine is to opening structure, by two split semicircle casings
The revolving body casing for being combined into a standard is bolted.Its structure is sufficiently complex, constitute include two end faces installation side,
4 intermediate circumferential installations while, 5 sections of outer cover cylinders, 4 it is longitudinally mounted while and 15 mounting bases, be made up of argon arc welding welding.Machine
The weld seam being covered on casket has: 10 circular welds, 4 longitudinal seams, 15 mounting bases circular weld, weld seam overall length exceedes 30 meters
There is very big welding stress in casing body after welding fabrication in (its middle cylinder body girth joint exceedes 22 meters).Casing it is sufficiently bulky,
But the wall thickness for constituting the outer cover cylinder of casing only has 1.2mm, and cylinder nearly all has milling slot in addition at mounting base position, and
It is only 0.65mm that cylinder wall thickness is smaller at milling slot.Casing cylinder poor rigidity.The manufacture of casing is that molding two is first respectively welded
Semicircle casing is bolted and constitutes back then by the opposite fitting two-by-two of 4 longitudinally mounted sides of two semicircle casings
The casing of swivel.In order to guarantee the binding face precision fitting on 4 longitudinally mounted sides, the revolving body casing an of standard is formed, is pacified
Rim binding face needs to carry out milling finish maching.Therefore, in prefabricated semicircle casing, all there are add for longitudinally mounted side binding face
Spare time amount, after semicircle casing welding fabrication, and welding stress is released, and recycles dedicated fitting device, passes through milling
The surplus on processing removal binding face is cut, plane precision is obtained and meets design requirement binding face, makes the vertical of two semicircle casings
It is fitted closely to installation side, forms the revolving body casing an of standard.
The processing of the longitudinally mounted side binding face of the prior art two semicircle casing companions, used fitting device are primary
It is only capable of the semicircle casing of installation processing one, two semicircle casings need to be processed successively respectively, i.e., first by a semicircle
Casing is mounted on fitting device, and machine tooling program is adjusted after being installed in place, to two longitudinal peaces of a semicircle casing
Rim binding face carries out Milling Process, and after Milling Process, lathe exits Milling Process program, by the semicircle casing from dress
It sets and disassembles, then another semicircle casing companion is processed according to this.It is processed using the fitting device of the prior art
The longitudinally mounted side binding face of two semicircle casings, since each program link of process of two semicircle casings is divided equally
It carries out twice, processing efficiency is relatively low, and processing cost is high.
Summary of the invention
For the deficiency of the longitudinally mounted side binding face processing unit (plant) of casing of the prior art, the purpose of the present invention is intended to provide
A kind of device of new construction processed for containing the split binding face of casing outside aero-engine, to improve casing installation side binding face
Processing efficiency, reduce processing and manufacturing cost.
Provided by the present invention for containing the device of the split binding face processing of casing outside aero-engine, constituting includes being used for
