Abstract
The utility model relates to a measuring tool for an assembly groove arc of a guide vane, which comprises a bottom plate, a base and a baffle, wherein the bottom plate is in a rectangular shape, and the base and the baffle are respectively fixed at the top end and the middle of the bottom plate; and a rotating shaft positioned in the center line of the bottom plate is arranged on the base and is fixedly provided with a measuring arm, and a lever dial indicator is arranged at the top end of the measuring arm. When measuring, the center of circle of the assembly groove arc to be measured coincides with the rotating shaft, and simultaneously, the probe of the lever dial indicator is exactly contacted with the assembly groove arc of the guide vane; and the rotating shaft coinciding with the center of circle of the assembly groove arc of the guide vane drives the lever dial indicator to draw an arc, thereby, whether the assembly groove arc meets the quality requirements or not can be quickly judged according to whether the reading of the lever dial indicator changes or not.
Description
Technical field
The utility model relates to a kind of measurer, particularly a kind of measurer of measuring guide vane fitting recess circular arc.
Background technology
Whether the steam turbine guide vane needs the fitting recess circular arc of detection guide vane to conform to quality requirements, so that guide vane when mounted can be smooth in process of production.Traditional detection method is: the simulation mounting plate of making various generation circular arc convex tendon according to the assembling circular arc of standard guide vane, observe by pre-assembled and to judge whether the fitting recess circular arc meets the requirements, detect very inconvenient, and the guide vane of different model need be made different simulation mounting plates, consumptive material is many, the cost height.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, the measurer that can conveniently check guide vane fitting recess arc accuracy.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of guide vane fitting recess circular arc measurer, comprise base plate, pedestal and baffle plate, described base plate is a rectangle, described pedestal and baffle plate are separately fixed at the top and the middle part of base plate, its innovative point is: described pedestal is provided with a rotating shaft that is positioned on the base plate center line, be fixed with the hollow framework in the described rotating shaft, be provided with the gage beam of a horizontal direction in the described framework, the end of this gage beam is connected with lever indicator, and in described framework upper surface the clamping screw that props up gage beam is housed.
Advantage of the present utility model is: during measurement, guide vane is placed on the base plate, the blade root radiant rays is overlapped with base plate center line, the blade lower surface props up baffle plate, the position of this baffle plate just makes that the fitting recess circular arc is the radius of guide vane assembling circular arc to the distance of rotating shaft, guarantees that the center of circle of the fitting recess circular arc of guide vane to be detected overlaps with rotating shaft.Adjust the length of stretching out framework of gage beam then by clamping screw, make the probe of lever indicator just contact with the fitting recess circular arc of guide vane, at this moment the reading of dial gauge is zero, stir gage beam then, the probe of lever indicator is that circle is drawn in the axle center with the rotating shaft, can change according to the reading of lever indicator and judge whether this fitting recess circular arc is qualified.
Description of drawings
Fig. 1 is the front view of guide vane fitting recess circular arc measurer of the present utility model.
Fig. 2 is the vertical view of guide vane fitting recess circular arc measurer of the present utility model.
Embodiment
As shown in Figure 1, 2, comprise base plate 1, pedestal 2, rotating shaft 3, framework 4, gage beam 5, clamping screw 6, dial framework 7, lever indicator 8, baffle plate 9.
Above-mentioned base plate 1 is a rectangle, the top is fixed with pedestal 2, one group of bearing is equipped with at these pedestal 2 centers, be provided with a rotating shaft 3 in the bearing, this rotating shaft 3 is positioned on the center line of base plate 1, and its top is fixed with a hollow framework 4, is provided with the gage beam 5 of a horizontal direction in this framework 4, the end of described gage beam 5 is connected with dial framework 7, on the described dial framework 7 lever indicator 8 is housed.A pair of clamping screw 6 is equipped with in the upper surface of framework 4, and its end face props up gage beam 5 and is used to be fixed in the framework 4, when needs are regulated the overhang of gage beam 5, unclamps clamping screw 6 and can adjust.The middle part of base plate 1 also is fixed with a baffle plate 9 perpendicular to center line, and after the position of this baffle plate 9 can make that the blade root end face of guide vane props up baffle plate 9, the fitting recess circular arc was the fitting recess arc radius of guide vane to the distance D of rotating shaft 3.
During use, the blade root end face of guide vane is propped up baffle plate 9, blade radiant rays and base plate 1 central lines, make the center of circle of fitting recess circular arc to be detected overlap with rotating shaft, adjust the extension elongation of gage beam 5, make the probe of lever indicator 8 just contact with the fitting recess circular arc of guide vane, at this moment the reading of dial gauge is zero, stir gage beam 5 then, it 3 is rotated around the shaft, the probe of lever indicator 8 is that circle is drawn in the axle center with rotating shaft 3, if changing, the reading of lever indicator 8 illustrates that then the radius of this fitting recess circular arc changes, do not meet quality requirements,, then conform to quality requirements if change in the error range that allows.
Claims (1)
