Description
Technical field
The invention belongs to assembling manufacturing technical field, especially a kind of narrow ring cavity depths clinching method and its dress work is sent
Tool.
Background technique
It is term durability gas turbine flame barrel as shown in Figure 1, burner inner liner structure in a ring, by outer ring assembly 1, interior ring assemblies 2, head
Component 3 forms, and the rivet 4 that different number is respectively adopted in outer ring assembly 1, interior ring assemblies 2 and head assembly 3 rivets, riveting location
Apart from burner inner liner ring cavity oral area 330mm.Burner inner liner ring cavity finish dimensional is 45mm, i.e. the right end outer ring inside radius and inner ring of Fig. 1
The difference of outer radius.When assembly, first in the assembling of ring assemblies and head assembly rivet, later outer ring assembly again with head assembly
Assembling riveting.
Presently, there are the problem of be: outer ring assembly and head assembly assembling rivet when, interior ring assemblies with head assembly
It assembles, forms annular chamber between burner inner liner inner and outer ring, riveting location is located at ring cavity depths, and ring cavity outlet size is small, and space is narrow
Narrow, hand rivet can not protrude into ring cavity depths, rivet is assembled in prefabricated hole, even if rivet is fitted into rivet hole.
Summary of the invention
The technical problem to be solved by the present invention is proposing a kind of ring cavity depths clinching method and sending holding tool, pass through rivet
Assembly tool, solution can not manually protrude into problem in narrow ring cavity, while rivet before riveting being avoided to be influenced and taken off by gravity
It falls.
Basic ideas of the invention: manufacturing and designing rivet and send holding tool, be placed on rivet send on holding tool first, rivet
Head is stuck between elastic piece and support plate, is acted on by elastic piece elastic force, and rivet is temporarily fixed on rivet assembly tool, later will
Rivet is sent into rivet hole, and the cylindrical section of rivet stretches out outside burner inner liner, secondly, manually holding the cylindrical section of rivet stretching, " is taken out
Holding tool is sent out ", then, snarls the cylindrical section that rivet stretches out outside burner inner liner with Medical adhesive plaster, rivet is temporarily fixed on flame
In the rivet hole of cylinder outer ring assembly and head assembly, finally, riveting clamp is protruded into annular chamber, support rivet head, removal doctor
With adhesive plaster, implement pier riveting.
It is combustion chamber flame drum as shown in Figure 1, burner inner liner structure in a ring, by outer ring assembly, interior ring assemblies, head assembly
Composition, outer ring assembly, interior ring assemblies are riveted on head assembly respectively using 90 rivets and 60 rivets, the cylindrical section of rivet
The ailhead thickness L of diameter of phi d, the ailhead diameter of phi d1 of rivet, rivet, riveting location is apart from burner inner liner oral area 330mm.Burner inner liner
Ring cavity outlet size is 45mm.
