Description

Middle rear body trailing edge bar angle processing tool

Technical field

The utility model relates to aeronautical product process technology, and being applicable to inner chamber has the very dark thin-wall part processing of closing angle, is specifically related to rear body trailing edge bar angle processing tool in one.

Background technology

In aircraft, the trailing edge bar body 02(of rear body is as shown in Figure 1), its profile is parallelogram, and structure is multiaspect milling structure substantially, thin-wall part, and inner chamber have a place very dark close angle 01.Add man-hour, close angle 01 place for very dark, size is difficult to ensure; And all will carry out milling processing for five faces of part, Set and Positioning is difficult; Also easily distortion is caused for thin-walled parts processing simultaneously.In the middle of processing in the past, because in such part, external form closes angle more, what have closes angle and could can only process on Five Axis high-speed machine tool, and therefore, such parts all need be processed on Five Axis high-speed machine tool before this.Because this volume of part is less, particularly deeply close angle 01 place, use that cutter is little and knife bar is long, five axle pivot angles processing are very easily quivered cutter at a high speed, affect wall thickness dimension, and easy breaking.The time taken on Five Axis high-speed machine tool is in addition also longer, adds the processing cost of whole part.

Summary of the invention

Technical problem to be solved in the utility model is the feature according to trailing edge bar, a kind of angle machining tool fixture is provided, part is not processed with five-axis machine tool, and just can be easy to setup on three axle lathes, ensure deeply to close angle locating and machining accurate, and prevent thin-walled parts to be out of shape, guarantee product quality, reduce production cost.

The utility model realizes above-mentioned purpose by the following technical solutions.Middle rear body trailing edge bar angle processing tool, comprise the first auxiliary fixture block of mainboard and the setting of trailing edge bar body wedge angle limit and the second auxiliary fixture block of two ends setting, the rectangular triangle of mainboard, one bar right-angle side is fixedly equipped with base plate, another right-angle side is fixedly equipped with side plate, and the side of mainboard is mounted by means of screws with pressing plate; First auxiliary fixture block and the second auxiliary fixture block of trailing edge bar body clamp the side being fixed on mainboard by pressing plate, and assist the dowel hole on the through hole of fixture block and mainboard to locate by second of trailing edge bar body.

The utility model has the advantages that, adopt auxiliary piece of technique to add sunk screw and compress, process in part placed angle frock, to ensure deeply to close angle processing dimension; Fine finishining adopts cushion block to pad, and has required support strength and rigidity when part is cut, and decreases the distortion of part web, ensure that product quality.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail.See Fig. 2 to Fig. 5, middle rear body trailing edge bar angle processing tool, comprise the first auxiliary fixture block 03 of mainboard 6 and the setting of trailing edge bar body 02 wedge angle limit and the second auxiliary fixture block 04 of two ends setting, mainboard 6 is triangle at right angles, one bar right-angle side is fixedly equipped with base plate 4, another right-angle side is fixedly equipped with side plate 5, and the side of mainboard 6 is installed with pressing plate 3 by screw 2; First auxiliary fixture block 03 of trailing edge bar body 02 and the second auxiliary fixture block 04 clamp the side being fixed on mainboard 6 by pressing plate 3, and assist the dowel hole 1 on the through hole of fixture block 04 and mainboard 6 to locate by second of trailing edge bar body 02.

embodiment:rear body trailing edge bar angle processing tool of the present utility model, two right-angle sides of mainboard 6 are fixedly connected with side plate 5 with base plate 4 respectively by screw.The flatness of base plate 4 and the perpendicularity degree of mainboard 6 and flatness need be ensured during installation, the crudy of part could be ensured like this in following process.During clamping, through hole on arranged by trailing edge bar body 02 two ends second auxiliary fixture block 04 and the dowel hole 1 on mainboard 6 are located, with pressing plate 3 and screw 2, part is fixed on the hypotenuse of mainboard 6 again, then two piece of first auxiliary fixture block 03 that trailing edge bar body 02 wedge angle limit is arranged is compressed by two block pressur plates 3 of side on mainboard 6 and screw 2, after fixing trailing edge bar body 02, alignment pin is extracted from dowel hole 1.Just can process the angle 01 of closing of trailing edge bar body 02 inner chamber.Ensure that and deeply close angle locating and machining accurately, also ensure that the processing dimension of deeply closing angle 01.

Claims (1)
