Abstract
The utility model discloses a universal milling fixture used for a guide vane of a water turbine. The universal milling fixture is characterized in that the fixture comprises a support base (1), a V-shaped installation groove (2) is disposed in the middle part of the upper end face of the support base (1), a V-shaped pressing plate (3) is correspondingly arranged above the upper end face of the support base (1), the two ends of the support base (1) are connected with the two ends of the V-shaped pressing plate (3) through adjusting bolts (4), and both the V-shaped installation groove (2) and the V-shaped pressing plate (3) are internally provided with half cushion covers (4). The universal milling fixture provided by the utility model has the advantages of simple structure and convenient operation; and with adoption of the fixture, the guide vane processed by a CNC milling machine is high in precision and excellent in quality, and the production cost is also reduced.
Description
Technical field
The utility model relates to a kind of universal milling machine fixture, particularly a kind of general milling clamper for guide vanes of water turbine.
Background technology
Stator is as a vitals in hydraulic generator unit, and the quality of its quality directly affects water inlet and the water shutoff of the hydraulic turbine.Traditional to the processing technology of stator in, after the axle journal of its stator is processed on horizontal lathe being put in place, use Kazakhstan furan cushion cover consistent by the journal size at diffuser two ends, pincers worker draws after blade profile line according to face mold on its end face, again two ends axle journal is pressed on planer, put in place according to line force plane, last pincers worker is breathed out furan model according to stator its polishing is put in place.Method is although it is so feasible, but in this processing method, the final molding of the molded line of diffuser leans on the polishing of pincers worker to guarantee, not only expense is time-consuming, and meanwhile, because the level height of pincers worker is different, it is second-rate that its molded line polishes out.
Utility model content
The purpose of this utility model is just to provide a kind of general milling clamper for guide vanes of water turbine that rear guide vane build linear dimension precision is high of processing.
The purpose of this utility model is to realize by such technical scheme, a kind of general milling clamper for guide vanes of water turbine, described fixture comprises bearing, middle part, upper surface at described bearing is provided with V-type mounting groove, above described bearing upper surface, correspondence is provided with V-type pressing plate, described bearing two ends are connected with the two ends of V-type pressing plate by adjusting bolt respectively, be provided with and breathe out furan cushion cover in described V-type mounting groove and V-type pressing plate.
Wherein, one end of described adjusting bolt is connected with bearing by pin, and the other end passes pressing plate and fixes by nut.
Position on milling machine for the ease of base, in the middle of the bottom of described bearing, be provided with keyway, be provided with location strong in described keyway, described location is strong to be connected with rest base by screw.
Owing to having adopted technique scheme, the utlity model has simple in structure, easy to operate advantage, adopt it not only can make to guarantee that the stator precision of CNC milling machine processing is higher, quality is better, meanwhile, has also reduced production cost.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state reference map of the present utility model.
The specific embodiment
