The support drill jig structure for drilling the double lug piece part comprises a drill jig body and a lug piece support, wherein a drill jig hole and a through hole connected with the lug piece support are formed in a drill jig plate of the drill jig body, a compression hole vertical to the through hole and a compression bolt are further located on the outer side of the drill jig plate, the lug piece support is of a structure composed of a hooked bolt and a hooked sleeve, two bending hook supports are respectively corresponding to two lug pieces of a part, a wedge groove is formed in the upper end of the hooked sleeve, and the compression bolt is pressed in the wedge groove through the compression hole.
Description
Technical field
The application relates to airplane parts manufacture, and the support of a kind of ears sheet part drilling is bored
Mode structure.
Background technology
Airplane parts is numerous and jumbled, different, and ears sheet part is one type, is characterized in ear
Sheet is thin, arm length.During ears sheet part drilling, tradition bushing plate auxiliary supports general by double
Head spiral shell, hex nut, adjusting nut composition, use string " sugarcoated haws on a stick " form during use.?
During machining, auxiliary supports and easily loosens, it is impossible to self-locking, product easily tremble cause overproof or even
Scrapping, workman wants repeatability to adjust in operation, poor operability.In order at limited sky
Interior elimination auricle vibration amount, guarantee machining accuracy, it is necessary to use suitable supporting way.
Summary of the invention
Add for the existing ears sheet part machinery of solution and easily tremble man-hour, yielding, limited
Space in can not support and the problem of self-locking simultaneously, the purpose of the application there are provided one
Can meet ears sheet part machinery simultaneously and add support in man-hour the function of self-locking, versatility is good, can
Strong operability, manufacturing cost is relatively low, is suitable to the ears sheet part drilling that this type of parts batch produces
Support Drilling Jig Structure.
A kind of support Drilling Jig Structure of ears sheet part drilling, containing model drilling body and auricle torr, its
Being characterised by, described model drilling body has a horizontal base, is provided with vertical on horizontal base
Benchmark is fast, and there is the connecting hole of fixing ears sheet part the side of reference block, in the upper end of reference block
Being provided with flat bushing plate, this bushing plate is provided with brill fenestra and the through hole of attachment lug torr,
Also a hold-down apertures being perpendicular to this through hole and hold-down bolt in the outside of bushing plate, described
Auricle torr is a structure being made up of hook bolt and hook-type sleeve, and the upper end of hook bolt has
External screw thread is also spirally connected with knurled nut, and its lower end forms crotch torr, and the body of hook-type sleeve is one
Individual sleeve, its external diameter mates with the through hole on bushing plate, and its internal diameter can be socketed in hook bolt
Body on, the side, lower end of hook-type sleeve extends into crotch torr, the crotch restitope of hook-type sleeve
Above the crotch torr of hook bolt, two auricles of two the most corresponding parts of crotch torr, hook
The sleeve upper end of shape sleeve is provided with wedge-shaped slot, and hold-down bolt is pressed on this wedge shape by hold-down apertures
In groove.
The application has the beneficial effects that, simple in construction, workable, wedge-shaped slot and compression
Bolt can realize quickly supporting and self-locking in the confined space, and manufacturing cost is relatively low, and versatility is good,
Can be used for the batch machining of same class part, therefore practicality is good, it is easy to popularization and application, has
Bigger practical value.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail.
Accompanying drawing explanation
Fig. 1 is the support Drilling Jig Structure signal of ears sheet part drilling
Fig. 2 is the cross-section structure signal of Fig. 1
Fig. 3 is that partial structurtes amplify signal
Fig. 4 is the signal of hook-type tube-in-tube structure
Numbering explanation in figure: 1 base, 2 benchmark are fast, 3 bushing plates, 4 brill fenestra, 5 annular knurls
Nut, 6 through holes, 7 hold-down bolts, 8 hook-type sleeves, 9 handles, 10 hook bolts, 11
Ears sheet part, 12 hold-down apertures, 13 wedge-shaped slots
Detailed description of the invention
Seeing accompanying drawing, the support Drilling Jig Structure of ears sheet part drilling, containing model drilling body and auricle
Torr, described model drilling body has a horizontal base 1, is provided with vertical base on horizontal base 1
Accurate fast 2, there is the connector of fixing ears sheet part 11 side of reference block 2, at reference block 2
Upper end be provided with flat bushing plate 3, this bushing plate is provided with brill fenestra 4 and attachment lug
The through hole 6 of torr, an also hold-down apertures 12 being perpendicular to this through hole in the outside of bushing plate 3
With hold-down bolt 7, described auricle torr be one by hook bolt 10 and 8 groups of hook-type sleeve
The structure of sum, there is external screw thread the upper end of hook bolt 10 is spirally connected, under it with knurled nut 5
End forms crotch torr, and the external diameter of hook-type sleeve 8 mates with the through hole on bushing plate, and its internal diameter can
To be socketed on the body of hook bolt 10, the side, lower end of hook-type sleeve 8 extends into crotch
Torr, the crotch restitope of hook-type sleeve 8 above the crotch torr of hook bolt 10, two crotches
Two auricles of the most corresponding part of torr, the sleeve upper end of hook-type sleeve 8 is provided with wedge-shaped slot
13, hold-down bolt 7 is pressed in this wedge-shaped slot 13 by hold-down apertures 12, and handle 9 is welded on
The lower end of hook-type sleeve 8.
During use, realized under part by the crotch torr of knurled nut 5 and hook bolt 10
The support of side's auricle, can quickly make the crotch torr of hook-type sleeve 8 support to zero by handle 9
Auricle above part, by adjusting housing screw 7, makes the screw bulb of housing screw 7 compress hook
The wedge-shaped slot 13 of shape sleeve from locking face, it is provided that the self-locking state of support.
