Abstract
The utility model relates to a rhombic moving blade root measuring instrument. The innovation points lie in that the measuring instrument comprises a rectangular template with a rhombic cavity formed in the center; four support pin shafts are respectively arranged on the two sides of inner wall of the cavity in pairs; and the upper end surface of the template is a convex arc surface. The utility model has the advantages that a blade root is embedded in the rhombic cavity of the template; the support pin shafts in the rhombic cavity of the template are used for supporting the whole moving blade; the upper end surface of the template is an arc surface with the radius identical to that of a circular arc on the upper end surface of the root of the moving blade; through comparing the upper end surface of the template with the upper end surface of the blade root, the processing quality of the circular arc of the blade root can be intuitively reflected.
Description
Technical field
The utility model relates to a kind of measurer, particularly a kind of measurer of measuring rhombus moving vane blade root locking hole and blade root upper surface circular arc.
Background technology
Steam turbine blade is the blade in company with the rotor high-speed rotation, by the high speed rotating realization air-flow of blade and the energy conversion between rotor.Moving vane bears very big mass inertial force, bigger aerodynamic force and oscillating load.Therefore moving vane is the vital part that directly influences engine performance, reliability and life-span.The design of moving vane, material select and make that very strict requirement is all arranged, and must keep aerodynamic configuration and very smooth surface accurately as blade, and material internal does not allow defective, and crystal grain is not too much etc.
When producing steam turbine blade, need test to the blade root upper surface arc accuracy of blade, so that the upper surface circular arc of the some blade roots in assembling back can encompass a circle, make it have good aeroperformance.And the blade root of most of steam turbine blades be fir-tree type is the inverted steps shape, and bottom area is less, vertically places easily swing, can't use traditional measurer of making basal plane with the blade root bottom surface to measure when therefore checking blade root upper surface arc surface, and is very inconvenient.
The utility model content
The technical problems to be solved in the utility model provides a kind of measurer that is convenient for measuring rhombus moving vane blade root locking hole and blade root upper surface circular arc.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of rhombus moving vane blade root is measured measurer, its innovative point is: described measurer has the rhombus cavity by rectangle template center and constitutes, described cavity inner wall both sides are respectively equipped with two and support bearing pin, and the upper surface of described template is a convex globoidal.
Further, also have the measured hole that passes rhombus cavity wall center on the described template, connect in the described measured hole and measure round pin.
Advantage of the present utility model is: the blade root of blade is entrenched in the rhombus cavity of template, utilize the support bearing pin in the template rhombus cavity to support the stepped end face of moving vane blade root, the template upper surface is radius and the identical arc surface of moving vane blade root upper surface arc radius, can react the crudy of blade root circular arc intuitively by the contrast of template upper surface and blade root upper surface.
When the blade root of blade was placed in the cavity of template, the position of measured hole was corresponding with standard moving vane blade root locking hole, by promoting to measure round pin, see whether it can enter in the blade root locking hole to be detected, can judge whether its this blade root locking hole position is accurate, contrast is directly perceived, the efficient height.

Embodiment
As shown in Figure 1, 2, 3, comprise template 1, support bearing pin 2, convex globoidal 3, measured hole 4, measurement round pin 5.
Above-mentioned template 1 is a rectangle, its center has the rhombus cavity, the cavity inner wall both sides are respectively equipped with two and support bearing pin 2, described support bearing pin 2 all stretches out inwall 4-6mm, and be positioned at same surface level, the upper surface of template 1 is a convex globoidal 3, and the arc radius of this convex globoidal 3 is identical with the arc radius of moving vane blade root upper surface.
Have the measured hole 4 that passes rhombus cavity wall center on the template 1, this measured hole 4 is positioned on the same axis with standard moving vane blade root locking hole, is connected with one in the measured hole 4 and measures round pin 5, and the diameter of this measurement round pin 5 is slightly less than measured hole 4.
When measuring blade root upper surface circular arc, as shown in Figure 4, in the rhombus cavity with the rhombus blade root embedded template 1 of blade, the support bearing pin 2 that stretches out in the cavity supports the stepped end face of moving vane blade root, can react the crudy of blade root circular arc intuitively by the template convex globoidal 3 and the contrast of blade root upper surface.When measuring the blade root locking hole, because the position of measured hole 4 is corresponding with standard moving vane blade root locking hole, by promoting to measure round pin 5, if it can enter in the blade root locking hole to be detected, illustrate that its this blade root locking hole position is accurate, otherwise be defective, contrast is directly perceived, the efficient height.
Claims (2)
1. a rhombus moving vane blade root is measured measurer, and it is characterized in that: described measurer has the rhombus cavity by rectangle template center and constitutes, and described cavity inner wall both sides are respectively equipped with two and support bearing pin, and the upper surface of described template is a convex globoidal.
2. rhombus moving vane blade root according to claim 1 is measured measurer, it is characterized in that: also have the measured hole that passes rhombus cavity wall center on the described template, connect in the described measured hole and measure round pin.
