Abstract

The invention provides a checking method for a three-dimensional combined sample plate of a cavity machining part. A profile sample plate is improved; an integrated sample plate which is composed of the profile sample plate and a reverse sample plate of the profile sample plate is taken; a suitable section sample plate is taken according to the conditions of the change in lateral angles of the part and the structure of the part, so as to form the three-dimensional combined sample plate; and by using the sample plate for checking, the angle can be quickly checked, the thickness of a lateral margin bar and the thickness and position of a rib of the part can be checked together, and the use is more convenient.

Description

The stereo assembled model method of inspection of cavity class machine-made spares

Technical field

The present invention relates to a kind of stereo assembled model method of inspection of cavity class machine-made spares, be used for machinery, aviation, automobile etc. are related to the check of cavity class machine-made spares.

Background technology

In the airplane parts process of manufacture; Can run into a lot of cavity class machine-made spares, they mostly side and bottom surface all have angle, and the part side wall thickness that has neither be uniform; So just give check, the check of especially producing aircraft in batches brings many troubles.

Traditional method of inspection of cavity class machine-made spares is that (web face) got exterior template in this type of part bottom surface, and then chooses suitable angle line by side curved transition situation.Though this method model design and use simply relatively when the check part, need be checked by aids such as bevel protractor and slide calliper rule, if check in enormous quantities, efficient is not high, and is easy to generate and thinks the check mistake.

In addition, utilize laser measuring apparatus to carry out component test in addition, though precision is high, checkability is not high equally.

To think that a kind of method of inspection is more efficiently sought in the check of producing aircraft cavity class machine-made spares in batches imperative to improve check speed and quality inspection.

Summary of the invention

The stereo assembled model method of inspection that the purpose of this invention is to provide a kind of cavity class machine-made spares; It is simple, convenient, fast to operate; Need not use other subsidiary instruments of inspections except that model, still can guarantee quality inspection, and improve efficiency of test.

Technical scheme of the present invention: the stereo assembled model method of inspection of cavity class machine-made spares comprises the steps:

1) gets standard cavity class machine-made spares, get exterior template and anti-model thereof in the bottom surface, constitute the one model by exterior template and anti-model thereof;

2) on the one model, mark part trim line, aperture and rib line, standard cavity class machine-made spares is positioned with trim line;

3) according to part side angle situation of change, get the tangent plane model, the tangent plane model is inserted sidewall;

4) below the tangent plane model, set up inserted sheet, on the one model, set up slot, pegging graft through inserted sheet and slot is fixed on the tangent plane model on the one model;

5) according to the quantity of tangent plane model at the enterprising line number of tangent plane model, and on the one model, make the numbering mark corresponding with the tangent plane model;

6) take off all tangent plane models and standard cavity class machine-made spares, part to be detected is placed on the one model, part to be detected is positioned, test one by one with the tangent plane model then with trim line.

The tangent plane of step 4) The midsagittal plane model will wrap up sidewall fully, and tangent plane model and sidewall stay the technology gap of 0.05mm-0.15mm.

Described tangent plane model adopts the mode of two parts butt joint to combine.

All tangent plane models and one model all have additional lifting hole(eyelet).

Beneficial effect of the present invention: the present invention adopts the stereo assembled model method of inspection can save the auxiliary instruments of inspections such as bevel protractor, slide calliper rule on the one hand; Make check more convenient; Traditional simple exterior template check and the laser measuring apparatus of relying on of checkability improved a lot, can detect part angle, lateral margin thickness, rib thickness and position etc. intuitively in addition; The tangent plane of tangent plane model will wrap up sidewall fully, and tangent plane model and sidewall stay the technology gap of 0.05mm-0.15mm, extracts so that can normally insert; Under the situation that if sidewall thickness is wide at the top and narrow at the bottom or other tangent planes can't insert, the tangent plane model adopts the mode of two parts butt joint to combine; In all models, increase the brill lifting hole(eyelet), can conveniently preserve.

Embodiment

The stereo assembled model method of inspection of cavity class machine-made spares comprises the steps:

1) as shown in Figure 1, get standard cavity class machine-made spares, as shown in Figure 3, get exterior template 4 and anti-model 6 thereof in the bottom surface, constitute one model 9 by exterior template 4 and anti-model 6 thereof;

2) continuation is as shown in Figure 3, on one model 9, marks part trim line, aperture and rib line, with trim line standard cavity class machine-made spares is positioned;

3) as shown in Figure 4, according to part side angle situation of change, get tangent plane model 8, tangent plane model 8 is inserted sidewall;

4) below tangent plane model 8, set up inserted sheet 1, on one model 9, set up slot 5, pegging graft with slot 5 through inserted sheet 1 is fixed on tangent plane model 8 on the one model 9;

5) according to the quantity of tangent plane model 8 at tangent plane model 8 enterprising line numbers, and on one model 9, make the numbering mark corresponding with tangent plane model 8;

6) take off all tangent plane models 8 and standard cavity class machine-made spares, as shown in Figure 6, part 10 to be detected is placed on the one model 9, with trim line part 10 to be detected is positioned, test one by one with tangent plane model 8 then.

The tangent plane of step 4) The midsagittal plane model 8 will wrap up sidewall fully, and tangent plane model 8 and sidewall stay the technology gap of 0.1mm.

As shown in Figure 5, described tangent plane model 8 adopts the mode of two parts butt joint to combine.

All tangent plane models 8 all have additional lifting hole(eyelet) 7 with one model 9.

The present invention improves exterior template 4, gets the one model 9 that exterior template 4 and anti-model 6 thereof are formed, and changes and the structure situation of part own according to part side angle simultaneously; Get suitable tangent plane model 8; The stereo assembled model of so just forming, with this model check, not only angle can be come out in quick test; And can also check out part lateral margin bar thickness and rib thickness and position together, use more convenient.
