Abstract
The utility model belongs to paddle amount of deflection measuring technique relates to anchor clamps that are used for measuring the paddle amount of deflection. The utility model discloses the commonality is strong, can be according to the needs of different model helicopter paddles, only need to change' but quick replacement centre gripping unit' and remove measuring unit and just to realize the measurement of multiple model paddle (including different length) amount of deflection. Make and need not the new anchor clamps of refabrication when the helicopter newly grinds the model, only need one purpose -built' but quick replacement centre gripping unit' to the constant growth of amount of deflection measurement anchor clamps quantity, development trial -production production cycle length in the helicopter triturating have been solved, manufacturing cost height, the problem that factory building usable floor area is nervous day by day.
Description
Technical field
The utility model belongs to blade deflection metrology technology, relates to a kind of fixture for measuring blade amount of deflection.
Background technology
After helicopter blade has assembled, before payment installation, generally need the amount of deflection (for verifying rigidity and the pliability of blade) detecting every sheet blade.At present, the model of helicopter is on the increase, because helicopter tonnage varies in size, the length of blade is obviously different, therefore the deflection metrology fixture needed is also along with increasing of model, and crossbeam increases, this situation causes the increase of aircraft manufacturing cost and newly to grind cycle of type elongated, also result in the usable floor area growing tension of factory simultaneously.
Summary of the invention
The purpose of this utility model is: the purpose of this utility model be to provide a kind of general deflection metrology fixture, with improve deflection metrology fixture versatility, reduce and increase new fixture because newly grinding model, reduce production cost, shorten the research and production cycle, save the usable floor area of factory building, realize energy-saving and cost-reducing.
The technical solution of the utility model is: a kind of frock clamp for measuring blade amount of deflection, is made up of: a base unit, a fast changeable grip unit following four kinds of elementary cells, a combined track unit and a measuring unit.Base unit is installed on ground, and for installing quick-replaceable grip unit, installed surface is horizontal plane.Quick replaceable grip unit is for clamping blade body, and the U-shaped clamping head and two be fixedly mounted on base unit by overlaps and forms for the bolt of locating blade.Combined track unit is surface-based two parallel orbits.Measuring unit is made up of a special long graduated scale and a sliding bottom; Install bottom sliding bottom and coordinate with track, special long graduated scale is vertically arranged on sliding bottom.
Further, described special long graduated scale is vertically arranged on sliding bottom by WidFin screw rod.
The utility model has the advantages that: this use novel universal is strong, can according to the needs of different model helicopter blade, only need to change the measurement that ' fast changeable grip unit ' and traverse measurement unit just can realize Multiple Type blade (comprising different length) amount of deflection.Make when helicopter newly grinds model without the need to manufacturing new fixture again, only need special one ' fast changeable grip unit ', thus solve deflection metrology fixture quantity in helicopter development process be on the increase, develop trial-production the production cycle long, manufacturing cost is high, the problem of factory building usable floor area growing tension.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.1 and 20 constitute base unit jointly, and 1 is cuboid type frame, and 20 is positioning screw screw bolt and nut.Fast changeable grip unit: 10,17 and 18 difference backstay, bolt, nuts; 2 be alignment pin, 3 for locating piece, 21 be nut, and 22 be lining, 24 is bolt.Combined track unit: 27 is two parallel orbits.Measuring unit: 4 movable scales, 5 holding screws, 6 bearings, 7 oilless bearings, 8 nuts, 9 backstays, 11,12,13 are respectively soket head cap screw, alignment pin, packing ring, 14 platforms, 15 support bars, 16 nuts.
Base unit of the present utility model, combined track unit and measuring unit need use three-dimensional location and installation, to ensure levelness and relative position.
Detailed description of the invention
Below the utility model is further described.
A kind of deflection metrology fixture, is made up of following four kinds of elementary cells: a base unit, a fast changeable grip unit, a combined track unit, a measuring unit.Base unit, for installing quick-replaceable grip unit, the cuboid-type shelf structure be made up of 17 rectangular steel-pipe weldings, upper surface has installation positioning jack, uses three-dimensional location (guarantee levelness) to be installed on facility floor.Quick replaceable grip unit, for clamping blade body, is made up of a U-shaped clamping head, two cover screw specials and nut, some fixing pins.Combined track unit is made up of two square steel parallel orbits and some hold-down screws.Measuring unit is made up of a special long graduated scale and a sliding bottom; Sliding bottom is cuboid-type shelf structure, and the pulley coordinated with track is installed in bottom.
Before measurement, need 10,17 and No. 18 parts be used to be fixed on base unit by ' the fast changeable grip unit ' of corresponding model as required.Then the blade using 2 and No. 21 parts to measure is fixed on the locating piece 3 of grip unit.Then allow blade freely descend to hang, by measuring unit by the blade tip position of combined track near blade, then regulate 4 movable scales by 9 backstays, make movable scale press close to blade tip, then read the reading of scale, this reading is the deflection value of blade.
Claims (2)
