Figure.
Referring to shown in Fig. 1 a-2c, in gas turbine manufacturing process, for every kind produced by hot investment casting process
Individual turbo blade casting requires usually after 1 Foundry Production of turbo blade comes out to the blade profile size of blade 11, edge
131 size of locking plate slot at 13 top of size and tenon tooth of plate 12 measures, so that the single blade for judging that Foundry Production goes out is
No is qualified product.
In existing measurement process, the measurement for blade profile size needs on special vice with a pair as shown in Figure 2 a
Roller 2 (having corresponding dedicated roller 2, that is, the roller 2 of different-diameter for the different types of design of blade 1) is clamped
Tenon tooth 13, elder generation's centering roller 2, for establishing coordinate system when Blade measuring, reuses special measuring tool and (does not regard in figure when measurement
The blade profile size of blade 11 is measured out).
Measurement for 12 size of listrium needs to clamp whole tenon tooths 13 using special measurement tooling as shown in Figure 2 b, will
Listrium 12 exposes, then the size of listrium 12 is measured with special measuring tool (not regarding out in figure).
Dimensional measurement for 13 locking tab slot 131 of tenon tooth need to use special measurement tooling to clamp tenon as shown in Figure 2 c
Tooth 13 simultaneously exposes apical tooth position, and the locking plate slot 131 is not blocked, and reuses special measuring tool (not regarding out in figure) survey
Measure 131 relative dimensions of locking plate slot.
Although the every kind of individual turbo blade 1 produced by hot investment casting process all accuracy with size obtain
The cylindrical false boss 14 of guarantee, but in existing production technology, the false boss 14 is mainly used for follow-up machine and adds process
Clamping and the purposes such as positioning, in existing measurement process, utilization physically is not carried out to the false boss 14 and (such as is pressed from both sides
The purposes such as hold, position).
As shown in Figure 2 a, during existing Blade measuring, the foundation of the theoretical reference coordinate system of the blade 1 is usually adopted
With following principle, (usually it is clamped in as shown in Figure 2 a described first with the roller 2 of the tenon tooth 13 of blade 1 described in held tight
First pair of recessed portion of 13 apical tooth two sides of tenon tooth) Lai Jianli datum plane, that is, the axis according to theoretical two parallel rollers 2
Line establishes x-y plane, and the axis by the cylindrical false boss 14 of the blade 1 is z-axis, the friendship of z-axis and x-y plane
Point is origin, and for x-axis by origin and parallel with the axis of roller 2, y-axis is vertical with x-axis.In the theoretical referring to seat of the blade 1
In mark system, z-axis is used to indicate positional relationship between the blade 11, the listrium 12 and the tenon tooth 13, usual situation its
It is oriented to the direction that the blade 11 is directed toward by the tenon tooth 13, x-axis and y-axis are mainly for for indicating the tooth of the tenon tooth 13
Shape, therefore the direction of x-axis and y-axis can (such as the matching of the reference coordinate system in measurement process with measuring tool facilitates journey as needed
Degree) it adjusts, that is to say, that the pointing direction of x-axis can be the direction that exhaust side is directed toward from blade leading edge, be also possible to
On the contrary, the pointing direction of y-axis is also possible to opposite either from the direction of leaf basin side direction blade back side.
It is above-mentioned in measurement process during being measured using different measuring tools or for different types of blade
Theoretical reference coordinate system can be translated according to the actual conditions of measuring tool, in other words, in order to which measuring instrument is convenient for reading, blade
1 theoretical reference coordinate system origin can mobile △ x, △ y, △ z on the direction of three reference axis respectively, so as to measurement
The reference coordinate system of instrument is overlapped.Certainly, it will be appreciated by those skilled in the art that for the ease of measuring instrument operation, such as scheme
Shown in 2b, 2c, the theoretical reference coordinate system of blade can also be rotated.
As previously mentioned, existing measurement process is to survey for the different turbo blades such as Fig. 1 a- Fig. 1 c
Tenon tooth 13 is clamped using special measurement tooling when measuring the blade profile of the blade 11 (such as to be pressed from both sides on special vice with a pair of of roller 2
Firmly first pair of recessed portion of the apical tooth two sides of tenon tooth 13) expose blade profile, it is positioned with tenon tooth 13 to measure blade profile size；In measurement tenon
When 13 locking tab 131 relative dimensions of slot of tooth, special measurement tooling is replaced, clamp most of tenon tooth 13 and will be revealed at the top of tenon tooth
Out, to measure 131 relative dimensions of locking plate slot；When measuring 12 size of listrium, it may be desirable to according to the variation of measuring point
Replacement covers special measurement tooling, clamps the exposing listrium 12 of tenon tooth 13 and is tested position, measures relative dimensions.
Above-mentioned existing measurement method, process very complicated, for example, clamping 2 clamping of roller using vice when measuring blade profile
During, the horizontality of two rollers 2 can finally influence the precision for the blade profile data that measurement obtains, therefore operator
It must the experienced efficiency that could ensure 2 process of clamping roller；And the special measurement for measuring listrium 12 and locking plate slot 131
Tooling clamps rear blade state if mounting groove gap is too big and is difficult to guarantee unanimously as shown in figs. 2 b and 2 c, can if gap is too small
Blade is caused to be difficult to pack into, therefore mounting groove manufacture difficulty is big, precision is difficult to guarantee.And in order to avoid causing to damage to blade,
Under normal conditions, the blade 1 can be less than for manufacturing the hardness of the material of special measurement tooling (especially installation groove location)
The hardness of material therefore in use, also easily cause the abrasion of mounting groove, to cause change in size.
In measurement process, since each measuring point requires special tooling, cause to require each blade
More set special toolings, so that production cost is high.In addition, tooling quantity also results in management difficulty more big, tooling
Maintenance difficulties increase.And since all processes are all manual operationss, the clamping measurement process of each size is both needed to grasp
Author has more skilled operation skill.
Existing measurement process operating efficiency is very low.For at least up to a hundred various blade essence castings of every batch of in actual production
Part finished product, since every blade is both needed to measure, measurement process needs to expend the very long time, drags to can become
One of an important factor for prolonging the entire production cycle.
