Abstract
The utility model relates to a blade drill jig for a hydrogenerator. The blade drill jig comprises a drill jig, a base and a blade, the base is arranged on an operating table of a drilling machine, the blade is mounted in the drill jig, the drill jig is positioned by an arc end face of the base and provided with two drill bush holes matched with the blades, a compression bolt is arranged on the drill jig, two positioning ribs are arranged on each of two sides of an inner cavity of the drill jig, and an compression bolt is arranged on the outer side of the drill jig. The blade drill jig for the hydrogenerator is simple in structure, convenient to clamp and adjust and accurate in drilling position, and labor intensity can be relieved for operators.
Description
Technical field
The utility model relates to a kind of hydraulic generator machine blade drill jig.
Background technology
A kind of rotary propeller type plano-convex aerofoil profile cast aluminum-molykote composite material fan of the normal employing of middle-size and small-size high speed water turbine generator, fan blade is single chip architecture, puts together on the fan seat ring with bolt; Two one or two of fan blade closes screw by circle distribution, and two screws are at a certain angle, and not at same plane; The bottom surface of fan blade is arc surface; The Drilling operation difficulty.Another kind is with the fan blade boring of ruling first, is that model is joined and bored the fan seat ring with fan blade again.The shortcoming of this practice is that the position of fan blade boring is inaccurate, and the center line in two holes has departed from the center of circle of arc surface, and the screwhole position of every place fan blade is all different with center line, and Drilling operation does not reach the specification requirement of drawing, and fan blade can not exchange.The Drilling operation difficulty is very large when changing after fan blade damages.It is also very difficult to join simultaneously brill fan seat ring.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and clamping is easy to adjust, and bore position is hydraulic generator machine blade drill jig accurately.
The technical solution of the utility model is achieved in that a kind of hydraulic generator machine blade drill jig, it comprises drill jig, base, fan blade, base places on the Drilling machines bench, fan blade is packed in the drill jig, drill jig is provided with two drill bushing holes that match with fan blade with base circular arc one end face location at drill jig, is provided with hold-down bolt at drill jig, respectively be provided with 2 positioning bars in the inner chamber both sides of drill jig, be provided with hold-down bolt in the outside of drill jig.
The utility model has the advantages that: simple in structure, clamping is easy to adjust, and bore position is accurate, can alleviate operator's labour intensity.
Description of drawings
Fig. 1 is clamping structure schematic diagram of the present utility model;
Fig. 2 is the top view structural representation of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, a kind of hydraulic generator machine blade drill jig, it comprises drill jig 1, base 2, fan blade 4, base 2 places on the Drilling machines bench, and fan blade 4 is packed in the drill jig 1, and drill jig 1 is located with base 2 circular arcs one end face, be provided with two drill bushing holes 6 that match with fan blade 4 at drill jig 1, be provided with hold-down bolt 5 at drill jig 1, respectively be provided with 2 positioning bars in the inner chamber both sides of drill jig 1, be provided with hold-down bolt 3 in the outside of drill jig 1.
