Description
Technical field
The utility model belongs to composite material manufacturing technology technical field, more particularly to a kind of composite structure connecting hole
Counter boring control structure.
Background technology
In order to ensure the good aerodynamic configuration in aircraft outer surface and attractive in appearance, the connection between aircraft housing parts is typically adopted
Use sunk screw.Therefore some composite material structural members after connecting hole is drilled, it is necessary in outside face ream system and sunk screw phase
The counterbore of matching.It is required that the axis of counterbore is consistent with connecting hole, counterbore depth matches with head of screw.
Traditional counter boring mode is using the connecting hole made, and socket drill positioning head is inserted in positioning hole and positioned
Counter boring.But the socket drill of rotation easily causes the damage of connecting hole positioning section at a high speed so that connecting hole borehole enlargement, overproof.
Counterbore depth and the operating experience of axis Main Basiss operator, the counterbore quality ultimately formed are unstable.Especially for some
The high composite material structural member of connecting hole required precision, it is easy to cause the connecting hole of composite material structural member overproof, influence to hand over
Pay.The accuracy of manufacture of counter boring counterbore how is improved, is a urgent problem to be solved.
Utility model content
Technical problem to be solved in the utility model is：A kind of composite material structural member connecting hole counter boring control knot is provided
Component, avoid connecting hole internal diameter from being sustained damage in counter boring, can strictly control counter boring depth, improve the manufacture matter of counter boring counterbore
Amount.
To reach above-mentioned purpose, implementation of the present utility model adopts the following technical scheme that：
A kind of composite material structural member connecting hole counter boring control structure, including alignment pin 1, handle 2, depression bar 3, wedge 4, company
Spindle 6, bottom plate 7, abutment sleeve 8, segmental support 9；Depression bar 3 is threaded rod, is loaded in the screwed hole on segmental support 9；Depression bar 3 it is another
One end loads in wedge 4；The both ends of bottom plate 7 are connected with segmental support 9 respectively by connecting shaft 6, and segmental support 9 can relative to bottom plate 7
Rotated along connecting shaft 6 in limited angular range；Abutment sleeve 8 is installed in the mounting hole among bottom plate 7.
The beneficial effects of the utility model：The utility model is by designing a kind of composite material structural member connecting hole counter boring control
Structure processed, the counter boring depth of composite material structural member can be strictly controlled, protect the damage from socket drill by the inwall of dimple rivet hole
Wound, improve counter boring quality.
Brief description of the drawings
Fig. 1 is general structure schematic diagram of the present utility model；
Fig. 2 is installation positioning schematic diagram of the present utility model；
Fig. 3 is counter boring process schematic；
Wherein, 1- alignment pins, 2- handles, 3- depression bars, 4- pressing plates, 5- composite material structural members, 6- connecting shafts, 7- bottom plates,
8- abutment sleeves, 9- segmental supports.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model composite material structural member connecting hole counter boring control structure, including alignment pin 1, handle 2,
Depression bar 3, wedge 4, connecting shaft 6, bottom plate 7, abutment sleeve 8, segmental support 9；Depression bar 3 is threaded rod, the screw thread loaded on segmental support 9
In hole；The other end of depression bar 3 loads in wedge 4；The both ends of bottom plate 7 are connected with segmental support 9 respectively by connecting shaft 6, segmental support 9
It can be rotated relative to bottom plate 7 along connecting shaft 6 in limited angular range；Abutment sleeve 8 is installed to the mounting hole among bottom plate 7
It is interior.
Referring to Fig. 2, alignment pin 1 is needed from composite material structural member 5 to pass through connecting hole by the side of counter boring, will be positioned
The opposite side of sleeve 8 from composite material structural member 5 is installed on alignment pin 1, and the upper surface of abutment sleeve 8 holds out against composite
The lower surface of structural member 5；Rotational handle 2, depression bar 3 is driven, wedge 4 is pressed on the upper surface of composite material structural member 5, by even
Connect together with hole counter boring control structure is fastenedly connected with composite material structural member 5；Now abutment sleeve 8, alignment pin 1, composite wood
Expect the three's axis coaxle of structural member 5.
Referring to Fig. 3, alignment pin 1 is removed, by the positioning section of socket drill 10 by needing the company of counter boring on composite material structural member 5
Hole is connect, is installed in abutment sleeve 8, socket drill 10 is rotated and carries out counter boring.The positioning section of abutment sleeve 8 and socket drill 10 coordinates,
The positioning section of socket drill 10 during counter boring can be avoided to, by the damage of dimple rivet hole inwall, being protected on composite material structural member 5 simultaneously
Demonstrate,prove counter boring direction of feed with abutment sleeve 8, it is consistent by the axis of dimple rivet hole；When in the front end face and abutment sleeve 8 of socket drill 10
Spacing end contact when, then stop counter boring, can so ensure counter boring depth meet require.
