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
Numbering explanation in figure: 1 part, 2 auricles, 3 auricle holes, 4 Master Datum Planes, 5 auxiliary datum planes, 6 flat board pedestals, 7 support rings, 8 support shafts, 9 bushing plates, 10 drill jig holes, 11 bracers, 12 locating pieces, 13 alignment pins, 14 connecting holes, 15 Anchor plate kits
Detailed description of the invention
See accompanying drawing, embodiment is as a example by the boring of the aircraft ears sheet part shown in Fig. 1, the material of this part is high strength steel, auricle hole 3 to be processed is positioned on the auricle 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 it is 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, it is known that the design theory digital-to-analogue of this part.
For the processing of this part, the present embodiment concrete scheme is as follows:
nullThere is a fixture，This fixture contains flat board pedestal 6、Bushing plate 9、Locating piece 12、Auricle supports and Anchor plate kit，Bushing plate 9 is fixed on flat board pedestal 6 by a bracer 11，Bushing plate 9 forms cantilever design，Drill jig hole 10 and threaded connection hole is had on bushing plate 9，Locating piece 12 is a wedge being fixed on flat board 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 additionally provided with alignment pin 13，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 support shaft 8 is parallel with two be fixed in support shaft 8，The two ends of this support shaft 8 are separately fixed on flat board pedestal and bushing plate，On the correct position of flat board pedestal and locating piece, additionally it is additionally provided with the connecting hole 14 of fixation clip assembly.
