Description
One, technical field
The utility model relates to a kind of blade special measurement instrument, especially is useful for the measurement of big blade profile of steam turbine and lacing hole position.
Two, background technology
Blade is one of part that most critical and kind are numerous and diverse in the steam turbine, and the quantity of blade accounts for 1/7 of steam-turbine parts number, so labor content is big.The processing of leaves quality all plays an important role to every performance index of steam turbine, for the machining shape complexity, and the blade that accuracy requirement is higher, survey instrument is absolutely necessary reliably.
The big blade profile of steam turbine is complex-shaped, and difficulty is measured in each sectional position, and especially the lacing hole center is with respect to the measurement of the axial and radial position degree of blade root reference for assembling.Usually adopt three-dimensional coordinates measurement profile and lacing hole, but this method need be through the special survey crew of Special Training, and measuring process is loaded down with trivial details, efficient is very low, as the method for taking to make conventional measurer is measured, the blade of different size will be made the measurer of multiple different size, and this not only makes troubles to the management work of production scene measurer, and causes the waste of more material and the increase of production cost.
Three, summary of the invention
The utility model purpose is to overcome the deficiencies in the prior art, proposes a kind of special measuring tool that is useful for different size, requires many grades of cross sections of MEASUREMENT OF STEAM turbine blade.Common engineering technical personnel can measure the profile of all kinds of big blades and the position of lacing hole accurately and rapidly.
The utility model is achieved through the following technical solutions: this gantry measuring tool is made of gantry frame, blade root location and clamp device, profile measurement model and lacing hole location measurement tool.
The gantry frame of described measuring tool, constitute by base plate, two side gussets, two side location-plates, two side positioning strips, top positioning plate, bottom locating piece and cross section positioning strip, two side gussets, two side location-plates, two side positioning strips, bottom locating piece are fixed between base plate and the top positioning plate, and the cross section positioning strip is fixed on the two side location-plates;
Described blade root location and clamp device are positioning reference with blade root inner arc, the blade root steam output side plane of blade, and the blade root back of the body arc voltage of blade is tight, and is fixed on the locating piece of bottom;
Described profile measurement model comprises the inner arc model and back of the body arc model of respectively measuring the cross section, and this model is provided with bound feet;
Described lacing hole location measurement tool is provided with lacing hole location measurement rod.
When using this gantry measuring tool to measure, corresponding locating surface on blade root inner arc, blade root steam output side plane and blade root location and the clamp device is close to, measure profile with each inner arc model of measuring the cross section with back of the body arc model (being the profile measurement model), according to the light leak size of model and blade profile, judge the profile shape error; According to model bound feet light leak, judge the site error of profile; Whether can pass through the blade lacing hole smoothly according to the length bar in the lacing hole location measurement tool, judge whether the blade lacing hole site is overproof.When measuring the blade of different cross section, only need be adjusted the cross section positioning strip according to each sectional dimension of drawing, change with the corresponding profile measurement model of tested blade, blade root location and clamp device, lacing hole location measurement tool to get final product.For the blade that the self-locking shroud is arranged, as long as many design one secondary shroud shape measure models can be measured.
The beneficial effects of the utility model are: this gantry measuring tool is not only convenient and simple for operation, and measurement is directly perceived, efficient is high, and has avoided the waste of material, has reduced production cost, the management space of having saved the production scene measurer greatly simultaneously.

Five, embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: the utility model gantry measuring tool comprises measuring tool gantry frame, blade root location and clamp device, one group of profile measurement model and a cover lacing hole location measurement tool.
As shown in Figure 1 and Figure 2: the measuring tool gantry frame comprises base plate 1, two side gusset 3, two side location-plates 8, two side positioning strips 14, top positioning plate 5, bottom locating piece 2, cross section positioning strip 4.All have the U-shaped locating slot on two side location-plates 8, bottom locating piece 2, the top positioning plate 5, its rigging position precision is located in the U-shaped locating slot by two side positioning strips 14, and screw retention can be guaranteed preferably.Cross section positioning strip 4 and two side location-plates 8 are by two side positioning strips, 14 location, and screw retention when measuring the blade of different cross section height, only need be unclamped screw, adjusts cross section positioning strip 4 to desired height up and down and can measure.
Blade root location and clamp device, this device are finally pack into the structures of race of a simulation blade, and the final reference for assembling of blade measuring basis and blade is unified mutually, reduce both positioning errors.This structure such as Fig. 1, Fig. 2, shown in Figure 4: comprise blade root inner arc locating piece 11, blade root back of the body arc voltage piece 10, base plate 15, blade root briquetting locating piece 16.During measurement, earlier this device is loaded on the bottom locating piece 2 of measuring tool gantry frame, with two side location-plates 8 and baffle plate 13 location, screw retention, then blade root inner arc, the blade root steam output side plane of tested blade are close to blade root inner arc locating piece 11, straight pin 9 respectively, screw screw 12, blade root back of the body arc voltage piece 10 is moved forward, clamp blade.This device location is reliable, clamping is convenient.
One group of profile model: comprise and respectively measure cross section inner arc model and back of the body arc model.As Fig. 5, shown in Figure 6, this model is provided with bound feet.During measurement, be placed on the cross section positioning strip 4,, measure the position and the shape error of blade profile with L shaped the location (shown in part among Fig. 1 6) on the cross section positioning strip 4.According to the light leak size of model and blade profile, judge the shape error of blade profile, according to model bound feet light leak whether, judge the site error of profile, this method is measured directly perceived, easy to operate.
Lacing hole location measurement tool: comprise measuring, length bar is as Fig. 7, shown in Figure 8.During measurement, after guaranteeing that the lacing hole aperture is correct, measuring is positioned L shaped last (shown in part among Fig. 1 7) of cross section positioning strip 4, insert with length bar in the hole of measuring, see whether length bar can as by then qualified, can't pass then defective smoothly by the lacing hole of blade, this operation is not only simple, and efficient is high.
This gantry measuring tool, as meet the blade of self-locking shroud, only needing the corresponding shroud templet of design, can be convenient for measuring.
