Description
Technical field
The application relates to airplane parts manufacture, the support Drilling Jig Structure of specifically a kind of ears sheet part drilling.
Background technology
Airplane parts is numerous and jumbled, different, and ears sheet part is a wherein class, is characterized in that auricle is thin, arm length.In ears sheet part drilling process, traditional bushing plate supplemental support is generally made up of double end spiral shell, hex nut, adjusting nut, adopts string " sugarcoated haws " form during use.When machining, supplemental support easily loosens, can not self-locking, and product easily trembles and causes overproof and even scrap, and workman wants repeatability adjustment in operation, poor operability.In order to eliminate auricle vibration amount in the confined space, ensure machining accuracy, suitable supporting way must be adopted.
Summary of the invention
Add easily tremble man-hour for solving existing ears sheet part machinery, yielding, can not support in limited space and the problem of self-locking simultaneously, the object of the application there are provided and a kind ofly can meet ears sheet part machinery simultaneously and add and support man-hour and the function of self-locking, versatility is good, workable, manufacturing cost is lower, is suitable for the support Drilling Jig Structure of the ears sheet part drilling that this type of parts batch is produced.
The support Drilling Jig Structure of a kind of ears sheet part drilling, containing model drilling body and auricle holder, it is characterized in that, described model drilling body has a horizontal base, horizontal base is provided with vertical benchmark fast, there is the connecting hole of fixing ears sheet part the side of reference block, flat bushing plate is provided with in the upper end of reference block, this bushing plate is provided with the through hole boring fenestra and attachment lug holder, a hold-down apertures perpendicular to this through hole and hold-down bolt is also had in the outside of bushing plate, described auricle holder is a structure be made up of hook bolt and hook-type sleeve, there is external screw thread the upper end of hook bolt is spirally connected with knurled nut, its lower end forms crotch holder, the body of hook-type sleeve is a sleeve, its external diameter mates with the through hole on bushing plate, its internal diameter can be socketed on the body of hook bolt, the side, lower end of hook-type sleeve extends into crotch holder, the crotch restitope of hook-type sleeve is above the crotch holder of hook bolt, two auricles of two corresponding parts of crotch holder difference, the sleeve upper end of hook-type sleeve is provided with wedge-shaped slot, hold-down bolt is pressed in this wedge-shaped slot by hold-down apertures.
The beneficial effect of the application is, structure is simple, workable, wedge-shaped slot and hold-down bolt can realize supporting fast and self-locking in the confined space, manufacturing cost is lower, versatility is good, can be used for the batch machining of same class part, and therefore practicality is good, be easy to apply, there is larger practical value.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail.

Number description: 1 base, 2 benchmark are fast, 3 bushing plates, 4 bore fenestra, 5 knurled nuts, 6 through holes, 7 hold-down bolts, 8 hook-type sleeves, 9 handles, 10 hook bolts, 11 ears sheet parts, 12 hold-down apertures, 13 wedge-shaped slots
Detailed description of the invention
See accompanying drawing, the support Drilling Jig Structure of ears sheet part drilling, containing model drilling body and auricle holder, described model drilling body has a horizontal base 1, horizontal base 1 is provided with vertical benchmark fast 2, there is the connector of fixing ears sheet part 11 side of reference block 2, flat bushing plate 3 is provided with in the upper end of reference block 2, this bushing plate is provided with the through hole 6 boring fenestra 4 and attachment lug holder, a hold-down apertures 12 perpendicular to this through hole and hold-down bolt 7 is also had in the outside of bushing plate 3, described auricle holder be one by hook bolt 10 and 8 groups, hook-type sleeve and structure, there is external screw thread the upper end of hook bolt 10 is spirally connected with knurled nut 5, its lower end forms crotch holder, the external diameter of hook-type sleeve 8 mates with the through hole on bushing plate, its internal diameter can be socketed on the body of hook bolt 10, the side, lower end of hook-type sleeve 8 extends into crotch holder, the crotch restitope of hook-type sleeve 8 is above the crotch holder of hook bolt 10, two auricles of two corresponding parts of crotch holder difference, 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, handle 9 is welded on the lower end of hook-type sleeve 8.
During use, the support to auricle below part is realized by the crotch holder of knurled nut 5 and hook bolt 10, the crotch holder of hook-type sleeve 8 can be made fast to support to auricle above part by handle 9, by adjustment housing screw 7, make the screw bulb of housing screw 7 compress the wedge-shaped slot 13 of hook-type sleeve from locking face, the self-locking state provided support.
