Abstract
The utility model discloses a kind of composite connecting-piece structure, belong to field of compound material.It is characterized in that connector head is square or hexagonal structure, transfer is prevented, afterbody is provided with laciniation, is firmly connected between composite body after pressurization.The beneficial effects of the utility model are can effectively to improve composite hole side bonding strength, and can obtain accurate drilling precision and assembly precision, solve the weak defect of long-standing problem composite perforate local strength.
Description
Technical field
The utility model is related to field of compound material, specifically a kind of composite connecting-piece structure.
Background technology
It is well known that after composite perforate, due to hole-edge stress concentration, causing after composite perforate under bonding strength
Drop, and composite quality hardness for metal is less than normal, after diameter connecting bolt, is especially subject to oscillating load condition
Under, composite hole can be expanded bigger and bigger, so as to cause connection to loosen and lateral opening destruction.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of sturdy and durable, connects reliable connector knot
Structure.By scientific design, reasonable construction gives full play to connector body construction metallic character, improves the connection of composite hole side
Intensity, and obtain the drilling precision and assembly precision of precision.
The utility model solves the technical scheme that its technical problem used：A kind of composite attachment structure, including
Head and afterbody, head are square or hexagonal structure, prevent transfer, and afterbody is provided with laciniation, after pressurization flange with
Firmly connected between composite body, laciniation is eight equal parts along border, and broached-tooth design is from tooth root to crown in 15 degree of cones
Angle, crown thickness is 1/3rd of tooth root.
The beneficial effects of the utility model are can effectively to improve composite hole side bonding strength, and can be obtained
Accurate drilling precision and assembly precision, solve the weak defect of long-standing problem composite perforate local strength.
Brief description of the drawings
The structural representation of Fig. 1 the utility model composite connectors.
Fig. 2 connectors of the present utility model be connected with composite after structural representation.
Embodiment
It is described in further detail below in conjunction with the accompanying drawings to of the present utility model, but protection domain of the present utility model
It is not limited to the embodiment.
As shown in Figure 1 and Figure 2, composite attachment structure 2, head is square or hexagonal structure, prevents transfer, tail
Portion is provided with laciniation, and flange is formed after pressurization and is firmly connected with composite 1.Laciniation is eight equal parts along border,
Broached-tooth design is in 15 degree of cone angles from tooth root to crown, and crown thickness is 1/3rd of tooth root.The utility model can be effective
Composite hole side bonding strength is improved, and accurate drilling precision and assembly precision can be obtained, long-standing problem is solved and is combined
The weak defect of material perforate local strength.
