Description
Technical field
The present invention relates to machining technology field, specifically a kind of adapter nozzle and its processing method.
Background technology
In starter for aircraft engine II leads part and belongs to overhaul consumable accessory, and adapter nozzle is II to lead important component part above part；It is II to turn on the phase accessory that adapter nozzle led with II in connecting shaft and be connected which acts on, and lubricating oil process adapter nozzle flows to II and leads the connecting shaft that leads with II.Because II lead connecting shaft work when, carry out rotating and producing substantial amounts of heat at a high speed, if the cooling without lubricating oil easily makes, and connecting shaft expansion is unstable to be caused to start accident, so adapter nozzle crudy directly influences lubricating oil and leads cooling with connecting shaft, and then the work of impact starter to II.
2 two parts welding fabrication of connecting portion of diversion division 1 and ring-type of such adapter nozzle by L-shaped（Such as Fig. 1）In reality processing, need to put down the 21 centering car of connecting end surface of connecting portion 2, and the end face outside car by 2 centering of connecting portion in through hole 22 goes out stage portion 25, the connecting end surface 21 of connecting portion and 25 butt tube nozzle of stage portion and II connection for leading connecting shaft play decisive role, therefore the flatness of the connecting end surface of connecting portion, the quality of through hole stage portion, are the key factors for affecting adapter nozzle to assemble quality.
The method for processing adapter nozzle in prior art is as follows：
A、
Place's polishing to be welded by connecting portion and diversion division；
B, connecting portion and diversion division are positioned and welded；
C, butt welding back part carry out penetrating inspection, and remove overlap；
D、
Butt welding back part carries out clamping；
E, processing connecting end surface and through hole, form stage portion, obtain adapter nozzle；
F, wash and check the adapter nozzle that obtains.
As connecting portion and diversion division can occur irregular deformation during welding, the therefore processing of the gentle stage portion of the car of connecting end surface needs to carry out after welding, just can guarantee that element precision, it is ensured that assembling quality.
In step D, to welding after adapter nozzle carry out clamping, existing clamping method has two kinds：One is using chuck clamping（Such as Fig. 2 and Fig. 3）Upper surface 11, lower surface 12, left side 13 and the right side 14 that four paws is distinguished clamping diversion division, as diversion division is that precision castings perpendicularity is not good, and diversion division and connecting portion deform in welding, through hole and endoporus are deformed, and take long enough to adjust in clamping centering connecting end surface, and the uniformity of the adapter nozzle size for processing is poor, greatly reduce working (machining) efficiency, it is impossible to meet processing needs.
Two is to carry out clamping using assembling clamp（Such as Fig. 4 and Fig. 5）Assembling clamp is fixed on lathe by three-jaw, the rear end face 15 of diversion division, lower surface 12, left side 13 and right side 14 are carried out positioning to rest against, and compress the upper surface 11 of diversion division, nozzle can quickly be will take over and complete clamping, simultaneously because the rear end face 15 to diversion division 1 is fixed, it is thus susceptible to for the connecting end surface 21 of connecting portion to carry out centering car put down, but as diversion division 1 is die casting, the perpendicularity of rear end face 15 is poor, the stage portion decentraction of diversion division endoporus and through hole after Vehicle Processing can equally be caused, it is impossible to meet assembling demand.
In sum, conventional frock major defect is as follows：Processing and loading clamp is difficult complicated, part crudy is difficult to ensure that, and process quality controllability is poor, machining accuracy cannot ensure, the adapter nozzle endoporus for processing and the concentricity of through hole stage portion are poor, and the flatness error of connecting end surface is larger, it is impossible to meet matching requirements, the part qualification rate for processing only has 50%, low production efficiency.
Content of the invention
In order to solve the above problems, the invention provides the adapter nozzle that clamping is simple in a kind of simple structure, process, concentricity and flatness precision are higher, easy to process and its processing method.
A kind of adapter nozzle, the adapter nozzle includes diversion division and connecting portion annular in shape, the diversion division is L-shaped, the endoporus along L-shaped insertion is provided with the diversion division, one end of the diversion division is weldingly connected with the medial surface of the connecting portion, the through hole is communicated with the endoporus, the through hole in the loop connecting portion is provided with stage portion, and the stage portion is located at the lateral surface of the connecting portion, the stage portion is arranged concentrically with the endoporus, during use, the stage portion is connected with the phase accessory socket of peripheral hardware, the lateral surface of the connecting portion is fitted with external part coupling as connecting end surface.
The processing method of above-mentioned adapter nozzle is specifically included：
A, by place's polishing to be welded of connecting portion and diversion division；
B, connecting portion and diversion division are positioned and welded；
C, butt welding back part carry out penetrating inspection, and remove overlap；
The soft pawl butt welding back part that D, use are matched with connecting portion profile carries out clamping；
E, processing connecting end surface and through hole, form stage portion, obtain adapter nozzle；
F, wash and check the adapter nozzle that obtains.
Further, in step D, used as face is rested against, the annular outer edge that soft pawl is compressed the adapter nozzle connecting portion, using dial gauge centering connecting end surface and the center of connecting portion for the medial surface using the adapter nozzle connecting portion；Connecting portion during positioning directly using adapter nozzle is used as benchmark, it is to avoid due to welding impact of the part distortion for causing to dimensional accuracy when carrying out indirectly centering by diversion division, it is ensured that machining accuracy.
The technique effect of invention：The adapter nozzle processing method of the present invention, relative to prior art, clamping is carried out using the soft pawl butt tube nozzle matched with adapter nozzle connecting portion annular outer edge during processing, it is to avoid the diversion division of adapter nozzle is used as fixed reference, so as to avoid the impact of butt welding pipe nozzle dimensioned precision；Medial surface using connecting portion is used as resting against face, soft pawl clamps the annular outer edge of connecting portion, convenient mounting and clamping, accurate positioning reliability, clamping force is easily controlled, clamping workpiece is firm, the crudy of product is stably improve, the stage portion of the connecting portion through hole for processing and the concentricity of the diversion division endoporus of adapter nozzle, the flatness of connecting end surface entirely reaches or has exceeded the required precision that product specifies, substantially increase production efficiency, reduce production cost, shorten the adapter nozzle production cycle, determine that positioning and clamping rests against face and design fixture provides reference for follow-up like parts.
