Abstract
The utility model relates to an anchor clamps are measured to ARC blade weight square includes mount pad (1), baffle (2), support bearing (3) and locating wheel (4). Being provided with on the excircle of locating wheel (4) and being surveyed blade tenon assorted recess, fix a position the blade tenon through two cylinder line contacts, a bearing is carried out transverse orientation in below support blade blade, baffle (2) to surveying the blade, has guaranteed the accurate location to the blade, centre gripping good reproducibility, convenient operation.
Description
Technical field
The utility model relates to aeromotor field, is specifically related to a kind of aeromotor arc shaped blade weight square measured material.
Background technology
For ensureing engine rotor counterbalance effect, needing to carry out the weighing of weight square to fan blade, carrying out sequence according to the circumferential erection sequence of leaf weight square to blade and make blade resultant moment vector minimum, to reduce the amount of unbalance of rotor.Engine blower blade is wide string arc shaped blade, and the face contact locator meams of leaf weight square measured material in the past can not be suitable for the measurement to this blade.
Summary of the invention
The purpose of this utility model is to provide a kind of arc shaped blade weight square measured material, to solve the problem that original fixture cannot measure arc shaped blade weight square.
The technical solution of the utility model is: a kind of arc shaped blade weight square measured material, includes mount pad 1, baffle plate 2, spring bearing 3 and locating wheel 4.Described locating wheel 4 is bolted and is arranged on mount pad 1, and excircle is provided with the groove matched with tested blade tenon.Mount pad 1 is also provided with block bearing 3, and spring bearing 3 can regulate the height of spring bearing 3 by upper lower nut.Be mounted by means of screws with baffle plate 2 at the side of mount pad 1, baffle plate 2 carries out located lateral to measured blade, guarantees that measure blade all leans against on baffle plate 2 at every turn.Adopt linear contact lay three-point fix mode, positioned blade tenon by two cylindrical wire contacts, a bearing, at supported underneath blade blade, ensure that the precise positioning to blade, clamps reproducible, easy to operate.
Alternatively, described locating wheel 4 is provided with register pin 5, the quantity of register pin is 2 ~ 4.
The utility model has the advantage of: a kind of arc shaped blade weight square measured material of the present utility model, achieves and measure the weight square of arc shaped fan blade, measure Stability Analysis of Structures, result is accurate, easy to operate, provides reliable leaf weight square data.By leaf weight square, fan blade circumference erection sequence is sorted, to reduce rotor unbalance value, thus reduce engine luggine risk.
By changing locating wheel 4, according to the groove on tested blade design locating wheel 4, then the height of corresponding adjustment spring bearing 3, the weight square of the arc shaped blade of different size can be measured.

Embodiment
Be described in detail of the present utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of arc shaped blade weight square measured material of the present utility model, includes mount pad 1, baffle plate 2, spring bearing 3, locating wheel 4 and register pin 5.Described locating wheel 4 is bolted and is arranged on mount pad 1, and locating wheel 4 is provided with 2 register pins 5, and register pin 5 accurately can be located locating wheel 4, and locating wheel 4 excircle is provided with the groove matched with tested blade tenon.Mount pad 1 is also provided with block bearing 3, and spring bearing 3 can regulate the height of spring bearing 3 by upper lower nut.Be mounted by means of screws with baffle plate 2 at the side of mount pad 1, baffle plate 2 carries out located lateral to measured blade, guarantees that measure blade all leans against on baffle plate 2 at every turn.Adopt linear contact lay three-point fix mode, positioned blade tenon by two cylindrical wire contacts, a bearing, at supported underneath blade blade, ensure that the precise positioning to blade, clamps reproducible, easy to operate.
In measurement procedure, directly the right side of blade to be measured from frock is put into, ensure that the tenon of blade is in the groove of the locating wheel 4 of fixture, carries out located lateral by baffle plate 2 pairs of blades, ensure that each blade of measuring all leans against on baffle plate.Simple to operate, and ensure that measurement accuracy and repeatability.
By changing locating wheel 4, according to the groove on tested blade design locating wheel 4, then the height of corresponding adjustment spring bearing 3, the weight square of the arc shaped blade of different size can be measured.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
