Abstract

The utility model discloses an aircraft airfoil chord is to appearance assembly and two unification cardboards of measuring function, including inspection cardboard, base block, butterfly nut bolt and locking bolt, two unification cardboards set up a set of base block to constitute on traditional inspection cardboard, should organize the base block symmetrical mirror like arranging on the inspection cardboard, and the airfoil chord is pressed to theoretical sharp processing to its terminal surface, center department opens on the base block has the spout, through the butterfly nut bolt fastening on the inspection cardboard, the flexible position of adjustable base block to fix on the inspection cardboard through two locking bolt lockings of taking the handle, when all base blocks when shrinking back the position, two unification cardboards can regard as the inspection cardboard to use, and when all base blocks were in stretching position, the terminal surface according to theoretical sharp processing on the base block can use as the assembly cardboard. The function that cardboard after the improvement will assemble cardboard sum check cardboard unites two into one, need not to change the cardboard, safety and stability, easy operation.

Description

The assembling of a kind of aircraft wing tangential profile and the two-in-one clamp of measuring ability

Technical field

The utility model relates to aircraft manufacturing assembling field, especially relates to the assembling of a kind of aircraft wing tangential profile and the two-in-one clamp of measuring ability.

Background technology

Aircraft wing aerodynamic configuration is an important indicator of aircraft components, generally comprises tangential profile and opens up to profile, and wherein tangential profile is generally checked by the inspection clamp amplifying 2-5mm by theoretical profile.Traditional frock type frame is generally provided with two cover clamps, a set of assembling clamp (the assembling clamp had is theoretical profile+part tolerance) for manufacturing by theoretical profile, the another set of inspection clamp for amplifying by theoretical profile.Two cover clamps are generally all arranged on same position, use same group of joint and latch to fix.In fitting process, in order to ensure External Shape, often needing to assemble clamp and exchanging with inspection clamp, check the assembly deflections situation in fitting process and final part payment profile.In order to ensure the rigidity of clamp, clamp is generally the thick steel plate manufacture of 30mm, wide about 20cm, and according to accessory size generally at 0.5-3m not etc., very heavy, workman's length requires great effort when changing clamp very much.And type frame generally has certain height, there is potential safety hazard in handling process.The most important thing is often to change the joint looseness that clamp also can cause clamp to be connected with type frame, latch is out of shape, and affects clamp precision, thus has influence on product design.

Summary of the invention

Goal of the invention: change difficulty to solve traditional clamp, handling process exists potential safety hazard, repeating to install affects the problems such as precision, and the utility model provides the tangential profile of a kind of aircraft wing to assemble and the two-in-one clamp of measuring ability.

Invention technical scheme: the assembling of a kind of aircraft wing tangential profile and the two-in-one clamp of measuring ability, comprise inspection clamp, matrix, fly nut bolt and lock bolt, it is characterized in that: two-in-one clamp on traditional inspection clamp, arranges one group of matrix form, the symmetrical mirror image of this group matrix is arranged on inspection clamp, its outer face presses airfoil chord to theoretical sharp processing, on described matrix, center has chute, be bolted on inspection clamp by fly nut, the telescopic location of adjustable matrix, described matrix two diagonal angles place also has chute, and be arranged on inspection clamp by the lock bolt of two band handles, for locking matrix, when all matrixs are in retracted position, described two-in-one clamp can be used as inspection clamp and uses, when all matrixs are in extended position, matrix can use as assembling clamp by the end face of theoretical sharp processing.Each matrix and matrix periphery inspection clamp are carved with mark, indicate matrix towards and with corresponding position relationship on inspection clamp, again playback when being convenient to matrix dismounting.

The beneficial effect of the invention: the function of assembling clamp and inspection clamp unites two into one by the clamp after improvement, without the need to changing clamp, safety and stability, simple to operate, and save a set of clamp and a set of clamp storage rack.

Detailed description of the invention

Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:

As accompanying drawing 1, shown in 2, the assembling of a kind of aircraft wing tangential profile and the two-in-one clamp of measuring ability, comprise inspection clamp 1, matrix 2, fly nut bolt 3 and lock bolt 4, this two-in-one clamp on traditional inspection clamp 1, arranges one group of matrix 2 form, first inspection clamp 1 is processed by numerically-controlled machine tool by the digital-to-analogue of inspection clamp, then one group of matrix 2 is processed, on each matrix 2, chute is outputed in center, and output chute at matrix 2 liang of diagonal angles place, join on inspection clamp 1 by pattern and get out the bolt corresponding with matrix 2 upper hopper chute just hole, then in first hole, the anti-wearing liner with bolt matching is pressed into, all matrixs 2 are arranged on inspection clamp 1 by fly nut bolt 3 and lock bolt 4, the outer face of airfoil chord to the digital-to-analogue processing matrix 2 of theoretical profile is pressed by numerically-controlled machine tool.By the telescopic location of fly nut bolt 3 adjustable matrix 2, and lock matrix 2 by the lock bolt 4 of two band handles, when all matrixs 2 are in retracted position, described two-in-one clamp can be used as inspection clamp and uses, when all matrixs 2 are in extended position, matrix 2 can use as assembling clamp by the end face of theoretical sharp processing.Each matrix 2 and matrix periphery inspection clamp 1 are carved with mark, indicate matrix 2 towards and with corresponding position relationship on inspection clamp 1, again playback when being convenient to matrix 2 dismounting.

Above-described embodiment; the just one of the utility model more preferably detailed description of the invention, the usual change that those skilled in the art carries out within the scope of technical solutions of the utility model, combination and replacement all should be included in protection domain of the present utility model.
