Definitions
- Test device test apparatus and test method for
- the present invention relates to a test specimen and a test device for profile grooves, in particular for Tannuten in wheels for mounting blades in turbines such as steam turbines of power plants.
- Blades of turbines in particular of a larger design, such as those used in power plants, are usually mounted with their blade root individually in profiled grooves, which are partially helically incorporated into the outer cylindrical surface of the wheels.
- Extending to the groove bottom towards ver ⁇ monyenden groove flanks have a plurality, typically three, opposing pairs of longitudinal grooves on, resulting in a typical cross-sectional shape of the groove profile yields, also referred to as "Tannennut”.
- the respective Obersei ⁇ th of the grooves forming supporting shoulders against which the corresponding mating shoulders of the blade roots are supported.
- the tolerances for the distance deviation of the opposing support shoulders from one another are 0 to -0.02 mm, for the parallelism deviation of the support shoulders to the nominal contour also from 0 to -0.02 mm, for the width deviation of the groove between +0.3 and -0.1 mm, for the height deviation in the range of 0.01 mm and for the deviation of the radius of curvature in the range around 0.02 mm.
- both groove flanks are milled together in one cut.
- both sides are milled individually Müs ⁇ sen. This leads to new sources of error.
- the cutter is pushed away by the one-sided engagement and the tracks can be milled eccentrically or offset in height.
- a geometric measurement of the groove profile is possible with coordinate measuring instruments and tactile buttons, but only for accessible spaces, which are usually available only at the beginning and end of the groove. This precludes continuous groove testing for acceptance testing and control of the manufacturing process. In addition, the measuring time of such a test is too long and not suitable for the factory.
- An object of the invention is to provide a testing device, a testing apparatus and a test method for profile grooves, in particular of grooved grooves in impellers for mounting blades on turbines, which make it possible to determine manufacturing errors with high accuracy, reliable and over the entire length of the groove.
- a test device for testing the cross-sectional profile of profile grooves, in particular of grooved grooves has:
- a substantially prismatic specimens with a cross section profile corresponding to the cross sectional profile of the profiled to examine ⁇ least in interest Konturabschnit- the support element and the groove bottom of the furrow grooves, is modeled, wherein the cross-sectional size of the fürturabschnit- the support element and the groove bottom of the furrow grooves is smaller than that of the groove, and a group of distance sensors, which are arranged in measuring surfaces of the test specimen, preferably perpendicular to this, wherein the
- a test specimen according to this aspect is thus formed in cross-section like a blade root of a rotor blade to be fastened in the groove. It forms, based on a radia ⁇ len section through the arc, which describes the blade groove, the counterpart to the formed as contact surfaces for the blade roots (support shoulders) profile area. Since the test specimen is smaller overall than the groove, it can be inserted into the groove and moved over the entire length of the groove. With the distance sensors arranged in the measuring surfaces, the distance of the same from the contour sections of interest of the groove, ie, the contact surfaces of the tine groove, can be determined. Since the contour of the test specimen and the position of the distance sensors is known, the geometry of the groove in the test cross section can thus be determined.
- this cross-section plane ⁇ defines the test section.
- the sensors are arranged in the middle cross-sectional plane of the test piece, so that the symmetry of the test piece can be utilized.
- This parallel measuring level defines a secondary measuring level.
- a plurality of partial bodies of the same cross-section are connected to one another in order to form the test body, wherein the distance sensors are each arranged in the connecting plane of two partial bodies.
- the cross-sectional shape of the specimen has a substantially trapezoidal basic shape, the oblique sides corresponding to the groove flanks and the narrow of the parallel sides corresponding to the groove bottom and defining a measuring surface, and a plurality, preferably two or three, projecting from the oblique sides, to the outside tapered and the bottom of the groove towards becoming smaller projections, wherein the upwardly facing sides of the projections each define a measuring surface.
- the specimen is adjusted to the pro ⁇ filform a Tannennut in wheels for mounting rotor blades on turbines.
- At least two distance sensors are arranged in the second measuring plane in the measuring surface opposite the groove base. Such an arrangement facilitates the use of the method in narrow measuring ranges, while with a wider measuring range at this point a distance sensor can be sufficient.
- measuring surfaces are provided, each of which faces a cone section of the groove, and at least one distance sensor is provided in each measuring surface opposite a cone section of the groove.
- Milling cutter regardless of other influences such as errors on the support flank angle, are determined. If the actual cone angle on the profile milling tool is known, the geomet- deviations resulting from the lateral milling cutter displacement and an error at the support flank angle are differentiated. Because these two disturbance variables can each be quantified independently of one another, the slot width for each required reference plane can be determined independently of any angular errors.
- the two distance sensors of each cone section are placed one above the other and arranged opposite their respective distance sensors on the other cone section.
- the test device has a Abdschreib worn for pressing the test piece from the groove bottom.
- the Ab ⁇ pressing device has in particular a pneumatic cylinder used in an axial bore of the test specimen and a punch, which is extendable by means of the action of the pneumatic cylinder of the bottom surface of the specimen on.
- the test piece can be pressed against the upper contact surfaces of the groove and aligned with these and fixed in the groove for the measurement.
- the stakes can be exchangeable.
- the push-off device may preferably be driven electromechanically.
- One or two grooves are preferably formed in the measuring surfaces defined on the upward-facing sides of the upper projections, in each of which an insert made of a wear-resistant material is arranged and fastened, the inserts rising slightly above the measuring surfaces.
- a defined nominal distance of the measuring surfaces is predetermined by the contact surfaces of the groove, a stable seat of the measuring device in the groove is achieved and wear on the measuring surfaces during frequent use is avoided.
- the distance sensors are particularly preferably fiber-optic distance sensors whose ferrules open in the measuring surfaces and whose optical fibers are laid inside the test body.
- the use of fiber-optic distance sensors in a test piece adapted to the shape of the groove allows a highly accurate measurement of the groove cross section and a compact Design.
- the fiber optic distance sensors integrate the actual sensor (the ferrule) with the supply line (the optical fibers).
- the ferrules can be placed with high precision in corresponding recesses and define the sensor position by their front end.
- the ferrules are made of a ceramic material and the optical fibers are fixed therein.
- a test apparatus for testing the cross-sectional profile of profile grooves, in particular fur grooves, a test specimen as described above and a control unit for driving the distance sensors and possibly the Abdschreib founded for receiving and evaluating signals from the Ab - Position sensors, and is set up to output evaluation results.
- a memory device for storing the evaluation results may also be provided. With such an apparatus, the signals of the distance sensors can be evaluated and made visible. In addition, a systematic and automatic testing of several test ⁇ cross sections is possible.
- a method of testing the cross-sectional profile of profiled grooves comprises the steps of: inserting a specimen as described above; Be ⁇ because of the test piece along the groove longitudinal direction up to a predetermined test cross-section; Moving the test specimen in the vertical direction until the test specimen is placed on the groove profile; Activating the distance sensors and receiving signals from them; and determining and preferably outputting a distance value for each distance sensor.

- Fig. 9 shows the area of the bottom surface 24 in an enlarged view.
- the essential difference between the test specimen 100 and the test specimen 1 lies in the arrangement of the distance sensors or measuring points (cf., FIGS. 8 and 9). (Due to the different arrangement, the counting of the measuring points also shifts.) The staggering (double occupation) of the distance sensors in the bottom surface 24 is eliminated. Thus, in the ground plane 24 in the primary measurement plane only two distance sensors (left and right one each) in the measuring points MP9 and MP10 and in the secondary measuring plane, only one distance sensor in the measuring point MP11 available. This eliminates three measuring points. The remaining measuring points lie in the outer area in order to obtain a good angular resolution over as large a distance as possible.
- test piece 1 can also be used without a movable holder. Namely, the test specimen 1 can also be manually inserted into the groove to be tested and moved to the desired test cross section, then the pneumatic cylinder can be activated and the measurement can be triggered.
- test specimen may also have measuring points in further measuring levels in addition to the main measuring level and the secondary measuring level.
- the test specimen 1 can have more than three part bodies. It is understood that the proposed test device for other groove shapes only requires a change in the cross-sectional geometry. In summary, the proposed test device allows the measurement of the relevant parameters, ie the support shoulder distances and angles as well as the groove width. These characteristics are important not only for the correct insertion of the blade feet, but also for an even load distribution in the later operation.
- test device for profile grooves can also be used for the analysis of existing processes in which reference has hitherto been made to the tool geometry. On the basis of the gained insights optimization steps for the process can be derived.
