Abstract
The utility model discloses a clamp for drilling normal direction holes. The clamp comprises a drilling jig body and a part positioning device. The drilling jig body comprises a curved surface which is matched with the outer surface of a part to be machined; the curved surface is provided with a plurality of through holes which have a normal direction with the curved surface; the part positioning device comprises a baffle plate which is fixed on one side of the drilling jig body and a plug which is fixed on the curved surface of the drilling jig body; and one side of the plug, which faces the axes of the holes, is matched with one end head of the part to be processed. The thin-walled part of which two sides are both the curved surfaces can be conveniently fixed on the clamp for drilling the holes, and the normal direction holes can be drilled on the part.
Description
Technical field
The utility model relates to a kind of aircraft manufacturing anchor clamps, specifically by model drilling body and the thin-walled shape part that the two sides is curved surface that is fixed in that part positioning device on the model drilling body forms bore the boring grab of method for making to the hole.
Background technology
In airplane parts was made, the thin-walled shape part that the two sides is curved surface was very general.In the part manufacture process, often on this part, bore method for making to the hole.The existing numerical-control processing method that adopts carries out the processing and the boring of this type part more.The position relation that the general processing of adopting the intact profile continued of digital control processing to carry out the normal direction hole guarantees profile and hole is correct.But when being on the thin-walled parts of curved surface processing normal direction hole on the two sides, because the part wall is thin, profile curvature is big, serious deformation can occur, the hole can't guarantee with profile position relation, and the impulsive force of generation caused defective when profile itself also can be owing to boring.Also be difficult to carry out clamping in the processing.Wasting time and energy in the normal direction hole that processes this type of part, takies Digit Control Machine Tool for a long time, out-of-tolerance parts occur and can't reprocess basically, thereby percent defective is high.
Summary of the invention
The purpose of the utility model is to provide a kind of normal direction hole drill hole anchor clamps.This normal direction hole drill hole anchor clamps not only can avoid thin-walled parts distortion in boring procedure, to occur, thereby make processing metapore and profile position relation correctly, and simple in structure, are easy to processing.
The normal direction hole drill hole anchor clamps of the utility model contain model drilling body and part positioning device, model drilling body comprise one with the suitable curved surface of part to be processed outer surface, have on the curved surface a plurality of and this curved surface established law to through hole; Part positioning device comprises the baffle plate that is fixed in said model drilling body one side and is fixed in the plug on the model drilling body curved surface that plug matches with part to be processed one termination towards the one side of axially bored line.
When adopting the boring grab of this spline structure to bore the normal direction hole on the thin-walled shape part that the system two sides is curved surface, because the curved surface of model drilling body pastes mutually on thin-walled parts band curved surface one side and the anchor clamps, strengthened part strength, part is not yielding during boring.Plug and baffle plate can accurately be located part rapidly, adopt the standard machinery method, through the normal direction hole of relevant position on the normal direction hole drill workpieces on the boring grab.This kind anchor clamps are particularly useful for producing in enormous quantities.This normal direction hole drill hole anchor clamps have not only solved the part deformation problem, and can not take the Digit Control Machine Tool resource, only hole with the conventional mechanical method.And the boring qualification rate is high, need not reprocess basically.
Below in conjunction with the embodiment accompanying drawing, the application done describing in further detail.

Numbering explanation among the figure: normal direction hole, 9 parts to be processed on 1 model drilling body, 2 baffle plates, 3 plugs, 4 curved surfaces, 5 normal direction through holes, 6, location side, 7 part curved surfaces, 8 parts
The specific embodiment
Shown in Figure 1 is the part to be processed sketch map.Part to be processed 9 is two thin-wall partses that are curved surface, and normal direction hole 8 is arranged on the part, part curved surface 7 for the anchor clamps curved surface that fits.Fig. 2 is depicted as normal direction hole drill hole anchor clamps, is made up of model drilling body 1, baffle plate 2 and plug 3, on model drilling body, has and the corresponding to curved surface 4 of part to be processed, and a plurality of normal direction through holes 5 vertical with this curved surface are arranged on the curved surface 4.Plug 3 carries out machining (adopting the numerical-control processing method once-forming) after can welding together (also can adopt method for distinguishing to fix) with model drilling body 1 more; Process the location side 6 of locating element on the curved surface that fits with part to be processed 94 and the plug 3; Location side 6 also is the positioning reference of part, and this side and curved surface and profile position relation will satisfy the alignment tolerance requirement.Bore a plurality of normal direction through holes 5 of system then.At last the baffle plate that processes 2 usefulness standard connectors are fixed in a side of model drilling body 1.
When boring on the system part to be processed 9 normal direction hole 8; As shown in Figure 4; Part curved surface 7 on the part fits with the curved surface 4 on the model drilling body; Location side 6 on part side and the model drilling body is accurately fitted, and with clamping tools such as arc pincers boring grab and part to be processed is clamped the back through the normal direction hole 8 on the 5 brill system parts to be processed of the normal direction through hole on the boring grab.
