Description
Technical field
The present invention relates to a kind of guide vane datum level positioning and processing method.
Background technology
Gas Turbine Power turbine guide vane sheet is precision pouring blade, material is special, hardness is high, shape is special, steam passage face is bigger, its assembling be pour into a mould later working portion steam passage position other assembled portion of processing, including blade root, integral shroud, into and out of vapour side plane etc., process and assemble also ensureing, working portion steam passage (steam passage cast is not processed later) is consistent, processing technique datum level includes blade root and leaf ejects the drop of vapour side plane and the processing of external arc operation, and it has a certain impact relative to the position of steam passage. Therefore will with the steam passage after cast and steam passage circular arc location, adding man-hour can't be excessive because of pressure, impression is left to steam passage, also to ensure that blade root and leaf eject the drop of vapour side plane and steam passage circular arc is accurate, thus ensureing that processing steam passage is consistent, therefore, the difficult point of processing is as how steam passage is the requirement of other fitting surface of position assurance.
Summary of the invention
The present invention is for solving in the course of processing of existing Gas Turbine Power turbine guide vane sheet location, there is steam passage and steam passage circular arc assembling location is inconsistent, it cannot be guaranteed that blade root and leaf eject the drop of vapour side plane and steam passage circular arc is accurate, and injure the problem of steam passage, and then provide a kind of Gas Turbine Power turbine guide vane sheet datum level positioning and processing method.
The present invention solves that the problems referred to above adopt the technical scheme that: a kind of Gas Turbine Power turbine guide vane sheet datum level positioning and processing method of the present invention carries out according to following steps:
Step one, utilize measurer to look for four points on the blade root face of Gas Turbine Power turbine guide vane sheet blank, and measure the size between these four points good and the drop of this relatively same datum level of four points;
Step 2, measure the surplus size of steam output side circular arc of Gas Turbine Power turbine guide vane sheet blank, and perform record;
Step 3, Gas Turbine Power turbine guide vane sheet blank are put on clamping and positioning device, six anchor points that the first positioning seat, the second positioning seat, the 3rd positioning seat, the 4th positioning seat, the 5th positioning seat and the 6th positioning seat are corresponding are measured, it is ensured that contact gap≤0.03mm with clearance gauge;
Step 4, on Digit Control Machine Tool with dial gauge and the numerical control Z axis coordinate readings drop centering to four points in step one, and four assistance for lifting adjusting supporting devices are adjusted location, Gas Turbine Power turbine guide vane sheet blank is raised 0.2mm-0.4mm while being compressed by Gas Turbine Power turbine guide vane sheet blank by four hold down gags;
Step 5, add man-hour, according to the peak in four points looked on the blade root face of the Gas Turbine Power turbine guide vane sheet blank in step one, the initial point of centering Tool in Cutting, process the position at this peak place, further according to the drop of centering in step 4, process other position, 3 places, till reaching size and the drop of designing requirement;
Step 6, the surplus size of Gas Turbine Power turbine guide vane sheet blank steam output side circular arc measured according to step 2, processing meets the circular arc of measurer, it is ensured that circular arc and measurer coincide, and Gas Turbine Power turbine guide vane sheet blank location machines.
The invention has the beneficial effects as follows: processing datum is to ensure that the steam passage of cast is consistent with steam passage circular arc, and therefore, the processing for this operation is particularly important, and it directly influences position degree and the geometric accuracy of postorder. Utilizing the positioning and processing method of the present invention, ensure that the technology requirement that steam passage is consistent with steam passage circular arc after processing, position degree and geometric accuracy effectively improve so that after meeting assembling, the technology of steam passage and steam passage circular arc has been required to meet the technology requirement of assembling. Accurate positioning, compress reliable, convenient and swift, processing is stable, and does not injure steam passage. Improve efficiency, reduce cost.
One, six point location positioners are manufactured according to principle of six-point fixing, it is ensured that accurate positioning.
Two, 3, the location of steam passage plane is point cantact steam passage, owing to the pressure of hold down gag easily causes impression, therefore, is mounted with four assistance for lifting adjusting supporting devices on the clamp body of guide vane blank plane being positioned at leading edge; Intensity in order to avoid impression and support point, increase assistance for lifting and regulate support location, four assistance for lifting adjusting supporting device location can support the face of roughing standard as the conversion of three-point fix, it positions conversion according to different guide vane black skins, it is to avoid the point of three-point fix is because the reason of pressure injures steam passage.
Three, four hold down gags ensure that the processing of guide vane blank is stablized and reliable, in order to ensure normal cutting, increase pressing plate, in order to fix workpiece on clamp body, it have to be ensured that there is pressing plates workpiece, but pressing plate to meet assistance for lifting regulates the position supported, it is to avoid pressure partially and weighs workpiece wounded.
Four, the present invention has innovated positioning and processing method, steam passage does not leave impression, ensure that blade root and leaf eject the drop of vapour side plane and steam passage circular arc is accurate simultaneously, thus ensureing that processing steam passage is consistent, improve efficiency, reduce cost, do not arrive size during original clamping processing work and just measure again, then centering again after clamping workpiece, reprocessing, repeated multiple times, efficiency is very low, and impression also easily occurs in steam passage. After the innovation of this processing method, once just can processing two planar dimensions and circular arc, it is ensured that size, drop, steam passage arc surface are fully completed, efficiency improves original three times, reduces cost. The innovation of the method is applicable to power turbine combustion pressure stator precision pouring blade.
