Description

Circular arc fir tree blade root measurement mechanism
Technical field
The utility model relates to a kind of measurement mechanism, is specifically related to a kind of circular arc fir tree blade root measurement mechanism.
Background technology
At present, in 300,000 kilowatts of Steam Turbine, final stage, inferior final stage moving blade blade root form adopt the circular arc fir tree blade root basically.The processing of circular arc fir tree blade root and measurement are difficult point and the emphasis during blade is produced always, and simple, efficient, low-cost and reliable measurement means is the key that guarantees the crudy of circular arc fir tree blade root.
Existing measuring method: generally be to adopt horizontal measurer, every kind of blade is joined a big base plate, and the blade of having built square chest crouches and is put on the measurer base plate; The diameter 10mm register pin of a plurality of length of assembling on the base plate; Be used for the position of positioning templet, register pin need exceed more than the base plate 100mm, measures the model that blade root circular conical surface and intermedium are used different band Ka Jiao respectively; The position degree of register pin and verticality are difficult to guarantee, and be very big to the measuring accuracy influence; Model 6mm is thick, and is yielding during manufacturing, comes to during measurement on the register pin, and locating surface is too little, measures inaccurate; The base plate cost is too high, and two sides require to have high machining precision for the Ka Jiao with model cooperates; Measurer is too big, stores inconvenient.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of circular arc fir tree blade root measurement mechanism that can realize efficient, low cost and reliable measuring.
Technical scheme: for solving the problems of the technologies described above, the circular arc fir tree blade root measurement mechanism of the utility model comprises measurer main body, side location-plate and circular arc molded lines measurement plate; Said side location-plate is positioned at measurer main body both sides and the measurer main body is fixed on the square chest; Two outsides that said circular arc molded lines is measured plate respectively with the measurer main body two in side contacts; The circular arc molded lines is measured both sides, plate upper end and is respectively equipped with projection Ka Jiao; The bottom surface of said projection Ka Jiao contacts with the upper surface of measurer main body, and the lower end that the circular arc molded lines is measured plate is the circular arc workplace.
For the ease of dismounting, said measurer main body is provided with handle.
For economical with materials and weight reduction, said measurer main body is provided with the lightening hole that is used for weight reduction.
Beneficial effect: the circular arc fir tree blade root measurement mechanism of the utility model, structure is ingenious, manufacturing is simple, and is higher to the accuracy of detection of arc surface; The not easy to wear and distortion of use, reliability is high; The critical piece versatility is good, can be used for measuring multiple blade.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
As shown in Figure 1, the circular arc fir tree blade root measurement mechanism of the utility model comprises measurer main body 1, side location-plate 2 and circular arc molded lines measurement plate 3; Side location-plate 2 is positioned at measurer main body 1 both sides and measurer main body 1 is fixed on the square chest 4; Two outsides that the circular arc molded lines is measured plate 3 respectively with measurer main body 1 two in side contacts; The circular arc molded lines is measured both sides, plate 3 upper end and is respectively equipped with projection card angle 7; The bottom surface at projection card angle 7 contacts with the upper surface of measurer main body 1, and the lower end that the circular arc molded lines is measured plate 3 is the circular arc workplace.
In the present embodiment, measurer main body 1 is provided with handle 5, can be so that dismounting; Measurer main body 1 is provided with the lightening hole 6 that is used for weight reduction, can economical with materials and weight reduction; The length direction of measurer main body 1 has register pin, and the position of register pin can the corresponding change according to the concrete condition of various blades 8.Square chest 4 the insides are cast with low-melting alloy: during beginning; Fix with watering the relative position of square chest 4 anchor clamps, pour into low-melting alloy then, after the low-melting alloy cooling blade 8 and square chest 4; Blade 8 just is fixed on square chest 4 the insides, processing and when measuring with square chest 4 as reference field.The circular arc molded lines is measured measurement model and the intermedium measurement model that plate 3 comprises blade root toothed section circular conical surface, and the measurement template line of blade root toothed section circular conical surface partly is processed into circular cone, measures a part of molded lines of blade root profile of tooth; It is different with the measurement model thickness of blade root toothed section circular conical surface that intermedium is measured the thickness of model, owing to the reference field of measurer main body 1 is fixed, so can only lean on the thickness of these several models to adjust the position of gage work face.
The utility model in use; Measurer main body 1 is put on the square chest 4 that processes the circular arc blade root; The length direction register pin is close to square chest 4, and two sides fix with side location-plate 2, respectively the circular arc molded lines are measured plate 3 and put into measurer main body 1; The locating surface of circular arc molded lines measurement plate 3 and the locating surface of measurer main body 1 are adjacent to; Measure the blade root circular conical surface or intermedium is measured the light leak gap between the plate 3 with the circular arc molded lines with clearance gauge, or measure the light leak gap between the plane on projection card angle 7 and the measurer main body 1 of circular arc molded lines measurement plate 3 with clearance gauge, judge according to each light leak gap, position whether workpiece processing is qualified:
(1) the inhomogeneous light leak in circular arc workplace place is explained the radiant rays malposition of arc surface, during the debugging lathe, at first will adjust the radiant rays position, guarantee the radiant rays correct position after, adjust other sizes again; (2) the even light leak in circular arc workplace place the radiant rays correct position of arc surface is described, but the blade root arc radius is ultra poor; (3) light leak gap, 7 place, projection card angle explains that arc surface does not have processing to put in place.
Surpass allowed band like the light leak gap, need the processing of adjustment back.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
