2) by parts fixation on above-mentioned fixture, the Master Datum Plane of part is placed on the locating surface of locating piece, the auxiliary datum plane of part leans against on the alignment pin of locating piece, part is fixed with the Anchor plate kit on locating piece by being fixed on plane bottom plate, the auricle of part is positioned at the below of bushing plate just, drilling position on auricle is coaxial with the upper drill jig hole of bushing plate, on auricle back shaft two support ring is adjusted its position on back shaft and fixing, make it just be supported on the below of auricle;

3), after completing parts fixation, the work top plane bottom plate of above-mentioned fixture being fixed on drilling machine carries out holing.

Beneficial effect of the present invention is, 1) bushing plate is fixed on the pedestal of clamp body, and its structure is simple, good rigidly, precision are high; 2) coordinate the space angle relation between part datum level and auricle by the wedge locating block be fixed on clamp body base, make part be convenient to processing; 3) supported by cantilever-shaped bushing plate by back shaft, the support ring be simultaneously fixed on back shaft is implemented to support to auricle, and during to offset boring, the power that auricle bears, ensures the machining accuracy of auricle part.

Below in conjunction with embodiment accompanying drawing, the application is described in further detail:

Accompanying drawing explanation

Fig. 1 is the signal of aircraft ears sheet design of part

Fig. 2 is drilling jig gripper structural representation

Fig. 3 is the signal of aircraft ears sheet drilling part method

Number description: 1 part, 2 auricles, 3 auricle holes, 4 Master Datum Planes, 5 auxiliary datum planes, 6 dull and stereotyped pedestals, 7 support rings, 8 bolsters, 9 bushing plates, 10 drill jig holes, 11 back-up blocks, 12 locating pieces, 13 alignment pins, 14 connecting holes, 15 Anchor plate kits

Detailed description of the invention

See accompanying drawing, embodiment is for the boring of the aircraft ears sheet part shown in Fig. 1, the material of this part is high strength steel, the auricle hole 3 processed is positioned on the ears sheet 2 of two, part 1 front end, accuracy class is IT7, the axis in auricle hole is vertical with auricle face, the Master Datum Plane 4 of part and auxiliary datum plane 5 are positioned on the I-steel matrix of part afterbody, and be all the space angle relation of an on-right angle between the auricle hole 3 of part, cause the bad control of drilling precision of such part, the design theory digital-to-analogue of this part known.

For the processing of this part, the present embodiment concrete scheme is as follows:

There is a fixture, this fixture contains dull and stereotyped pedestal 6, bushing plate 9, locating piece 12, auricle supports and Anchor plate kit, bushing plate 9 is fixed on dull and stereotyped pedestal 6 by back-up block 11, bushing plate 9 forms cantilever design, bushing plate 9 there are drill jig hole 10 and threaded connection hole, locating piece 12 is the wedges being fixed on dull and stereotyped pedestal, the inclined-plane of wedge is the locating surface of locating piece, this locating surface is parallel with the Master Datum Plane 4 of part 1, locating surface is provided with alignment pin 13 in addition, this alignment pin 13 is corresponding with the auxiliary datum plane 5 of part 1, described auricle supports and is made up of the support ring 7 that bolster 8 is parallel with two that are fixed on bolster 8, the two ends of this back shaft 8 are separately fixed on dull and stereotyped pedestal and bushing plate, the connecting hole 14 of fixation clip assembly is also provided with in addition on the correct position of dull and stereotyped pedestal and locating piece.
