Abstract
The utility model relates to a milling clamp of the back arc of a gas passageway of a blade of a steam turbine, which comprises a bottom board and a work table arranged on the bottom board, wherein one end of the work table is articulated with the bottom board, the other end of the work table is connected with the bottom board through a spring, the work table is provided with a rotatable crank, one end of the crank is provided with a molded line cushion block for clamping the blade and a press ring sheathed on the molded line cushion block, and the other end of the crank is provided with an explorator. The milling clamp has the following advantages: when milling, the clamp is arranged under a cutter bar of a milling machine; the cutter bar of the milling machine is provided with an assembled cutter and an idler wheel, which correspond to the positions of the molded line cushion block and the explorator; and the blade to be milled of the back arc of the gas passageway is arranged on the molded line cushion block of the clamp, and the two ends of the blade are fixed through the press ring. When rotating the crank, the outline of the explorator is always tightly adhered to the idler wheel under the function of the spring, so that the assembled cutter can mill the blade to be a structure which is the same as the outline of the explorator, and has one-step forming and high machining efficiency.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of turbine blade steam passage back of the body arc milling fixture that can a milling moulding.
Background technology
Turbine blade is interior conversion of air-flow function and the strength member that changes airflow direction realized of the gas channel of steam turbine.The blade of steam turbine is made up of blade and blade root two parts, and blade is blade has blade profile in gas channel a part, and when the steam passage back of the body arc of milling blade, traditional method for milling is to mill into cambered surface again after milling in advance, needs twice milling moulding, and efficient is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of turbine blade steam passage back of the body arc milling fixture that can a milling moulding.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of turbine blade steam passage back of the body arc milling fixture, comprise base plate and be located at workbench on the base plate, its innovative point is: an end and the base plate hinged of described workbench, be connected with spring between the other end and the base plate, rotating crank throw is housed on the described workbench, and described crank throw concave surface is provided with the molded lines cushion block that clamps blade and is enclosed within trim ring on the molded lines cushion block, also is provided with pattern on the crank throw concave surface.
Advantage of the present utility model is: during milling, anchor clamps are placed on the knife bar below of milling machine, be equipped with on the knife bar of milling machine and molded lines cushion block, corresponding gang tool and the roller in pattern position, the blade for the treatment of milling steam passage back of the body arc is placed on the molded lines cushion block of anchor clamps, and fixes the two ends of blade by trim ring.During the rotation crank throw, under the effect of spring, the outline of pattern is close to roller all the time, and gang tool mills out the structure identical with the pattern outline, one-shot forming, working (machining) efficiency height with blade like this.
Description of drawings
Fig. 1 is the structural representation of turbine blade steam passage back of the body arc milling fixture of the present utility model.
Fig. 2 is the side view of turbine blade steam passage back of the body arc milling fixture of the present utility model.
The specific embodiment
As shown in drawings, comprise base plate 1, workbench 2, spring 3, crank throw 4, molded lines cushion block 8, trim ring 9, pattern 10.
Above-mentioned base plate 1 is provided with workbench 2, and an end and the base plate 1 of this workbench 2 are hinged, is connected with several springs 3 between the other end and the base plate 1.Workbench 2 is provided with rotating crank throw 4, its two ends are by the upper surface of bearing block support at workbench 2, crank throw 4 is realized its rotation by the worm and gear transmission, worm gear 5 is fixed on the end of crank throw 4, worm screw 6 is located on the workbench 2, and with worm gear 5 engagement, and handwheel 7 is housed at the end of worm screw 6.
Crank throw 4 concave surfaces are provided with molded lines cushion block 8 and the trim ring 9 that clamps blade, molded lines cushion block 8 and finished blade concavity profiling, blade can be placed on the molded lines cushion block 8, and its inner arc and molded lines cushion block 8 are fitted, the back side to be processed up, two trim rings 9 are enclosed within the two ends of blade respectively.The other end of concave surface is provided with pattern 10, and the outline of this pattern 10 is the back of the body arc profile of standard turbine blade.
During use, also supporting on the knife bar of milling machine have gang tool 11 and a roller 12, and the lower surface of described gang tool 11 flushes with the lower surface of roller 12.During milling, vanes fixed is shaken handwheel 7 on crank throw 4, make crank throw 4 rotate, under the effect of spring, the outline of pattern 10 is close to roller 12 all the time and is moved, and when pattern 10 moved on roller 12, blade to be processed also was close to gang tool 11 and is done identical moving, 11 pairs of blades of gang tool mill out and the identical structure of pattern 10 outlines like this, once can milling finish, need not twice processing, improved efficient.
