Abstract
The utility model relates to a kind of double fork-join header structures, belong to assembly structure design field.General double fork-join heads generally use overall processing, and fork ear portions are worked into drawing size by the way of wire cutting or milling.Fork ear locating piece higher for some required precisions, machining are easy to produce machining deformation, are influenced by machining stress, it is difficult to guarantee the Geometrical Tolerance Principles such as the depth of parallelism of two positioning surfaces and the verticality in face and hole.The utility model proposes a kind of double fork-join header structures, and including seperated fixture block, fork auricle one and fork auricle two, fixture block has connecting plate in end face, and fork auricle one and fork auricle two are separately mounted on two sides of fixture block.It avoids being deformed in process, optimizes joint structure.
Description
Technical field
The utility model relates to a kind of double fork-join header structures, belong to assembly structure design field.
Background technique
Connector locating piece is usually used in being fixedly connected for the important docking site of airplane component, the rigidity of connector locating piece and
Processing accuracy directly influences the safety of aircraft product, and process and assemble quality is the key that entire tooling type frame.
As shown in Figure 1, general double fork-join heads generally use overall processing, fork ear portions use the side of wire cutting or milling
Formula is worked into drawing size.Fork ear locating piece higher for some required precisions, machining are easy to produce machining deformation, by
Machining stress influences, it is difficult to guarantee the Geometrical Tolerance Principles such as the depth of parallelism of two positioning surfaces and the verticality in face and hole, this state
Under reprocess also more difficult, possible brand-new can just obtain ideal pieces O.K. several times, cause larger waste.
Utility model content
The technical problem to be solved by the utility model is to proposing a kind of double fork-join header structures, avoid producing in process
Change shape, optimizes joint structure.
A kind of double fork-join header structures have connection in end face including seperated fixture block, fork auricle one and fork auricle two, fixture block
Plate, fork auricle one and fork auricle two are separately mounted on two sides of fixture block.
The connecting plate is welded with fixture block or overall processing is integrated.
Auricle one, fork auricle two and fixture block are pitched by cylinder finger setting, is linked together by bolt, washer and nut.
Bushing is installed in the connecting hole of fork auricle one and fork auricle two.
Bushing is fixed by gap gluing.
Pitching auricle one and fork auricle two has pairs of multiple groups connecting hole.
The utility model has the advantages that optimizing design of part, guarantee size and geometric tolerance convenient for manufacture.
Detailed description of the invention
Fig. 1 is existing double fork joint part schematic diagrames；
Fig. 2 is the schematic diagram of the double fork-join header structures of the utility model.
Specific embodiment
Connecting plate 1 and the welding of fixture block 2 or overall processing are integral, and fork auricle 1 and fork auricle 24 recline fixture block 2 respectively
Two sides, two fork auricles and fixture block 2 be fixed together after determining position by bolt, washer, nut, straight pin, fork
Bushing 5 is installed in connecting hole on auricle 1 and fork auricle 24.Bushing 5 fork auricle 1 and fork auricle 24 on be by
Gap gluing is fixed.
Double fork-join header structures are designed as separate structure group under conditions of guaranteeing that positioning surface part is constant by the utility model
It closes.
Fixture block 2, fork auricle 1 and fork auricle 24 are processed by drawing size tolerance requirements respectively respectively first, and guaranteed
Each plane is bright and clean enough, installs bushing 5 in the connecting hole on fork auricle 1 and fork auricle 24.Common process mode can guarantee
Part size, and it is not likely to produce deformation.
Then fixture block 2 is weldingly fixed on connecting plate 1, there are part weld seam in two sides, so two sides fork auricle 1, fork ear
When the positioning plate of piece 24 is connect with fixture block 2, palpus cut-out gets out of the way welded seam area.In the bushing pitched auricle 1, pitch auricle 24
Technique bolt is packed into 5.After fork auricle 1, fork auricle 24 and fixture block 2 are combined into the part size for meeting drawing requirement, lead to
Spiral pin nail is crossed to be fixedly connected.The deformation influenced in the process without stress release, process operation is easy, concentricity and face
The depth of parallelism be all easier to reach the part requirements of landing nipple.
