Description
Technical field
The invention belongs to aeroengine combustor buring room nozzle manufacturing technology, it is related to a kind of retaining mechanism of nozzle assembly.
Background technology
Nozzle assembly is the significant components in engine fuel nozzle, is assembled through technique and the lock that closes up by spout and vortex pad
Formed after tight, it is desirable to which its coating surface position should seal oil-proof after vortex pad and spout locking, and closing in position should be uniformly complete,
Existing technological method for processing is to close up to lock with operating experience using 3 punching pines of different structure, in processing, due to closing in portion
Position be located at spout inner chamber, closing in process be difficult directly observation and control, in addition closing in punching pin and inner bore of nozzle exist it is certain between
Gap, closing in punching pin is to empirically determine with the relative position at part closing in position, and component closes up after locking, is tried in follow-up flow
When testing, often there is flow value wild effect, during the nozzle assembly dissection and analysis after locking that will close up, discovery has closing in portion
There is fast phenomenon at the edge of position, and closing in position is circumferentially uneven, and at closing in position, the thinning degree of part material is inconsistent etc.
Problem, the problem has a strong impact on the normal development of new machine product.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of retaining mechanism of nozzle assembly.
The present invention is achieved by the following technical programs.
A kind of retaining mechanism of nozzle assembly that the present invention is provided；Including segmental support and punching pin component, the upper end of segmental support
Face is parallel with lower surface, there is spout groove on lower surface, has punching pin hole in the spout groove vertical area on upper surface, and punching pin component can
With through punching pin hole.
Described punching pin component is divided into punching pin A, punching pin B and punching pin C.
Cone tank arranged at described punching pin A and the bottom of punching pin B, and punching pin B bottom pyramidal grooves height than punching pin B tapers
Groove height is low.
The height of described punching pin B bottom pyramidal grooves is segmental support/2 of punching pin B taper groove heights.
Described punching pin C bottom surfaces are planar structure.
The beneficial effects of the present invention are：Shell nosing treatment is carried out to nozzle assembly by the device, it is ensured that nozzle assembly
During closing in, closing in instrument is accurately positioned with the closing in position of nozzle assembly, it is ensured that the locking quality of nozzle assembly, improves
Production efficiency, it is ensured that new machine product is smoothly developed.

Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
A kind of retaining mechanism of nozzle assembly as shown in Figures 1 to 3；Including segmental support 1 and punching pin component, segmental support 1
Upper surface is parallel with lower surface, there is spout groove 11 on lower surface, has punching pin hole 12 in the vertical area of spout groove 11 on upper surface,
Punching pin component can pass through punching pin hole 12.
As shown in figures 4-6, described punching pin component is divided into punching pin A21, punching pin B22 and punching pin C23；Described punching pin A21
There is cone tank with the bottom of punching pin B22, and the height of punching pin B22 bottom pyramidal grooves is lower than punching pin B22 taper groove heights, it is described
Punching pin C23 bottom surfaces be planar structure.
Further, the height of described punching pin B22 bottom pyramidal grooves is the segmental support 1/2 of punching pin B22 taper groove heights.
Nozzle assembly of the present invention is as shown in figure 1, including spout 31, vortex pad 32, wherein needing processing simultaneously
Locking position 33 on non-spout 31.
During operation, first nozzle assembly is placed on segmental support 1, the spout 31 of wherein nozzle assembly is placed on segmental support 1
On spout groove 11 in, it is ensured that nozzle assembly is vertically-mounted；
Taken out after being closed up to the locking position 33 of nozzle assembly in punching pin hole 12 with punching pin A21 from segmental support 2；
Then taken after being closed up to the locking position 33 of nozzle assembly with punching pin holes 12 of the punching pin B22 from segmental support 2
Go out；
Then taken after being closed up to the locking position 33 of nozzle assembly with punching pin holes 12 of the punching pin C23 from segmental support 2
Go out；
Finally taken out from segmental support 1 with by nozzle assembly.
