Abstract
The invention provides a sealing assembly assembling tool and method. The tool comprises a base, a positioning sleeve arranged at the upper end of the base in a matched manner, and a punch arranged in the positioning sleeve in a sleeved manner. The base is provided with a positioning hole used for containing a small end outer cylinder face of a metal component. The large end of the positioning sleeve is used for being arranged on a large end outer cylinder face of the metal component in a sleeving manner. The small end inner diameter part and the outer diameter part of a non-metal component are matched in a sleeved manner. The punching end of the punch is a protruding annular punch. The outer diameter of the punch is the same as the outer diameter of the non-metal component. The positions of to-be-assembled components in a clamp are limited by adding the positioning sleeve, the component base and the punch of the clamp and the two to-be-assembled components are connected through the positioning sleeve in series and are kept with the center consistency.

The assembling requirement can be met, the design and concept are ingenious, and the structure is compact; and the manufacturing cost is low, using is easy, and operation is convenient.
Description
Technical field
The present invention relates to a kind of assembling of two kinds of unlike material sub-assemblies, be specially a kind of black box assembly tooling and method.
Background technology
Black box is one of strength member in aero-engine, as shown in Figure 1.Sealing assembly non-metal workpiece (polytetrafluoroethylene (PTFE)) is pressed into the new parts formed in the dovetail groove of metalwork, requires after mounting: 1, nonmetal parts must be full of in metalwork groove completely, must not have space; 2, nonmetal parts and metalwork press-fit rear junction and will fit tightly, and seamless, require metal and nonmetallic surface interface place, the 10 times of lens examinations in the A place namely in Fig. 1 do not allow the gap being greater than 0.1mm.
For assembling jig unlike material part being formed a new parts by embedded mode, adopt in prior art and metal parts is put into assembling jig base locating hole, by placed on it for another non-metal workpiece, in assembling jig, without locating piece, restriction is positioned to this non-metal workpiece radial position, drift one end is pressed on non-metal workpiece, beat the drift other end with hammer, under pressure at right angle effect, non-metal workpiece is pressed in metal parts dovetail groove, is illustrated in fig. 2 shown below.There is following drawback in above-mentioned existing assembling jig:
This assembling jig pointing device design defectiveness, only define position to one of them workpiece, another workpiece is spacing to it without setting element in assembling jig, is in free state, and whole fixture location owes location.This assembling jig intention by: (1) positions metal parts by clamp base, (2) take non-metal workpiece to be enclosed within the pin of fixture drift, to utilize on the drift pin leading portion conical surface and metal parts centre bore 60 ° of conical surfaces to locate centering to realize realizing assembling jig to the method for non-metal workpiece radial location and locate, but there are some problems in practical operation, location intention cannot be realized: on (1) pin front end conical surface and metal parts end-face central hole, 60 ° of conical surfaces are too short, cause location unstable, (2) design drawing has requirement to fitting temperature, in order to avoid causing fitting temperature to decrease beyond set point of temperature lower limit due to heat radiation, assembly manipulation must be rapidly, fast, when punch head is close to metal parts centre of surface hole, the non-metal workpiece be enclosed within drift pin just can be slipped on metal parts large end face before prerequisite located by drift, cover central hole location, operator accurately cannot locate centering in hasty, in fact non-metal workpiece is press-fiting front position to one side play, often on the skew be pressed in dovetail groove, non-metal workpiece is caused fully not fill up in dovetail groove, even produce and be not pressed onto bottom land phenomenon, there is assembly quality hidden danger.
Summary of the invention
For problems of the prior art, the invention provides one can locate completely by all parts to be assembled radial direction in fixture, prevents Assembly of the parts position to be installed from offseting the black box assembly tooling and the method that cause assembly quality defect.
The present invention is achieved through the following technical solutions:
A kind of black box assembly tooling, comprises base, is equipped with the positioning sleeve in base upper end, and be set in the drift in positioning sleeve; Described base is provided with the locating hole of the small end external cylindrical surface for laying metal parts; The large end of described positioning sleeve is for being set in the large end external cylindrical surface of metal parts, and small end inner diameter is set with the external diameter of non-metal workpiece and coordinates; The punching press end of described drift is in protruding annular punch, and the external diameter of drift is identical with the external diameter of non-metal workpiece.
Preferably, in drift, the radial thickness of annular is greater than the radial thickness of the non-metal workpiece of annular.
Preferably, the non punching end setting operation bulb of drift.
Preferably, the large end of positioning sleeve is that concentric two-stage stepped hole is arranged, and from this termination, the degree of depth in first order hole is outside to inside not less than the thickness of the large end of metal parts and is less than the thickness of the large end of metal parts and the thickness sum of non-metal workpiece.
Preferably, described depth of positioning hole is greater than the height of the small end outside cylinder of metal parts.
Based on a black box assembly method for the black box assembly tooling in the present invention, comprise the steps,
Step 1, is placed in base on workbench, takes out the to be assembled metal parts of temperature between 150 DEG C-160 DEG C and non-metal workpiece from resistance furnace;
Step 2, puts into the locating hole of base by the small end cylindrical of metal parts;
Step 3, is placed on the large end cylindrical of metal parts by large for positioning sleeve end endoporus;
Step 4, puts into positioning sleeve small end endoporus by non-metal workpiece;
Step 5, being pressed in downwards along the inwall of positioning sleeve small end endoporus by punch end foldedly drops on together etc. on non-metal workpiece to be assembled and metal parts, exert a force to the drift other end along centre of location direction, under pressure non-metal workpiece is pressed in the dovetail groove of metal parts, completes assembling and obtain black box.
Compared with prior art, the present invention has following useful technique effect:
The positioning sleeve of the present invention by increasing, define the respective position of part to be assembled in fixture, component chassis in fixture, drift and two parts to be assembled are concatenated by positioning sleeve and make their maintenance centers consistent, eliminate former assembling jig owing to lacking setting element, Assembly of the parts position to be assembled is uncertain and the assembling defect caused.The present invention can meet matching requirements, and design concept is ingenious, compact conformation, low cost of manufacture, uses simple, easy to operate.
Further, by the restriction to punch reaction surface, make itself and non-metal workpiece contact area greatly, active force is uniform and stable, ensures that non-metal workpiece can enter completely when punching press, meets processing request.
Further, the bulb arranged is utilized can to ensure to facilitate stable applying active force; The location to metal parts can be better met by the setting of stepped hole, and simultaneously to the constraint of non-metal workpiece, avoid play and crooked generation.
