Abstract
The utility model relates to a tooling for processing the convex surface of a steam turbine blade. The tooling comprises a baseplate and a working platform arranged on the baseplate, and is characterized in that the top end of the working platform is hinged with the baseplate, a fixing seat and a press plate for fixing the blade are mounted on the upper end surface, a cavity is arranged at the tail end, a swinging nut is arranged in the cavity, rotating shafts connected with the working platform are arranged on the two sides of the swing nut, and a swinging screw rod matched with the swinging nut is arranged at the tail end of the baseplate. The utility model has the advantages that when in use, the blade is fixed on the working platform through the fixing seat and the swinging press plate, and the convex surface is machined by a milling cutter profiling with the convex surface of the blade. When the clamping angle is required to be changed, the swinging screw rod is swung, so that the swinging nut in threaded fit therewith rises to drive the whole working platform clamping the blade to rotate around a hinge at the top end, thereby realizing the change of the clamping angle.
Description
Technical field
The utility model relates to a kind of machining frock, particularly a kind of processing tool of turbine blade convex surface.
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, when the blade convexity face of processing T type blade root, adopts anchor clamps to clamp blade, uses the milling cutter that has with this convex surface profiling to carry out milling then.And the blade of different convex surface radial angles need use the anchor clamps of different clamping angles, needs the anchor clamps quantity of preparation many, and consumptive material is many, the cost height.And these anchor clamps floor spaces are big, can't be placed on the milling machine workshop entirely, and each use need be come from the other places carrying, and is very inconvenient.
The utility model content
The technical problems to be solved in the utility model provides a kind of turbine blade convex surface processing tool, can regulate according to different convex surface radial angles and clamp angle, need not to make the multiple anchor clamps that clamp angle, has saved cost.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of turbine blade convex surface processing tool, comprise base plate, be arranged on the workbench on the base plate, its innovative point is: described workbench top and base plate hinged, upper surface are equipped with the holder and the pressing plate of fixed blade, end has cavity, be provided with the swing nut in the described cavity, the rotating shaft that is connected with workbench is equipped with in described swing nut both sides, and is provided with and swings the swing screw rod that nut cooperates at described base plate end.
Advantage of the present utility model is: during use, blade pass crosses holder and the swing pressing plate is fixed on the workbench, uses with the milling cutter of blade convexity face profiling and processes.When needs change the clamping angle, rotate the swing screw rod, feasible swing nut with its threaded engagement rises slightly, drives the hinge through of the workbench of whole clamping blade around the top, thereby realizes clamping the change of angle.
Description of drawings
Fig. 1 is the structural representation of turbine blade convex surface processing tool of the present utility model.
Fig. 2 is along the cutaway view of A-A line among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, comprise base plate 1, workbench 2, holder 3, swing pressing plate 4, side guide 5, swing nut 6, swing screw rod 7.
Above-mentioned base plate 1 is provided with workbench 2, and the top of this workbench 2 and base plate 1 are hinged, and the upper surface is provided with holder 3 and the swing pressing plate 4 that is used for fixing blade.The structure of described holder 3 is: have a groove on the holder 3, a side of described groove is the inclined-plane, and it is provided with the side guide 5 of pushing down the blade blade, and the bottom of groove is an arc shaped surface cushion block.Swing pressing plate 4 is arranged on the pedestal 8 at holder 3 rears, and its middle part is connected with pedestal 8 by rotating shaft 9, and its top has the inclined-plane of a flare, and end is equipped with a bolt 10 that props up workbench 2.Be used to promote the end of swing pressing plate 4, make the end chamfer of swing pressing plate 4 sink to propping up blade.
The end of workbench 2 has a cavity, is provided with swing nut 6 in it, and the rotating shaft that is connected with workbench 2 is equipped with in these swing nut 6 both sides, makes swing nut 6 to rotate in the cavity of workbench 2.The base plate 1 of swing nut 6 belows is provided with swing screw rod 7, and dome shape is processed in the end of this swing screw rod 7, makes its body of rod to shake on base plate 1, and the body of rod of described swing screw rod 7 passes swing nut 6 and stretches out.
During use, blade is placed in the groove of holder 3, its convex surface for the treatment of milling up, blade is pushed down by side guide, the bolt of pendulum rotating dynamic pressure plate 4 ends makes the end of swing pressing plate 4 sink, its inclined-plane props up the end of blade, finishes clamping of blade.When needs change the clamping angle, rotate the swing screw rod 7 that stretches out swing nut 6, swing nut 6 risings with its threaded engagement drive the hinge through of the workbench 2 of whole clamping blade around the top, finish the adjustment that clamps angle.
