Description
Technical field
The utility model relates to a kind of keyway specific frock, is mainly used in the keyway of 76000 tons of rudder for ship leaf endoporus of processing, belongs to and builds the ship equipment technical field.
Background technology
76000 tons of rudder for ship leaves, its endoporus have a keyway, and it is safeties that prevent that the rudder stock lower bearing from rotating, though keyway is little, acts on very big.How to carry out the problem that this keyway has become a key, because the rudder blade workpiece is bigger, its appearance and size is long 9.6 meters; Wide 5.5 meters, high 0.9 meter, weigh 35 tons; And always outside the workshop moulding bed make blank, outer boring endoporus, the installation of can directly going on board after the pincers worker brush.Can 76000 tons the rudder for ship leaf many this keyway, to advance to land on the workshop boring processing by routine, cost is too high like this, lift by crane, and transports, process time is long again.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of 76000 tons of rudder blade keyways processing special tooling is provided, and it is easy to operate, and shorten process time greatly, reduced production cost.
The purpose of the utility model is achieved in that a kind of 76000 tons of rudder blade keyways processing special tooling, and it is characterized in that: it comprises location-plate, and horizontal guide rail and three alignment pins are installed on the said location-plate; Said three alignment pins are evenly arranged on the same circumference, and the circumcircle diameter of three alignment pins is identical with the diameter of bore of rudder blade, and vertical guide rail and support nut are installed on the said horizontal guide rail from left to right successively; Said support nut is provided with the stretching screw mandrel, and stretching screw mandrel one end is connected with the vertical guide rail back side, and the other end is provided with handwheel; Said vertical guide rail front is provided with the motor slide plate, and the back side is set with the jacking nut, and said motor slide plate front is set with motor; The back side is set with Standing-up support; Said Standing-up support is provided with the jacking screw mandrel, and said jacking screw mandrel one end is connected with Standing-up support, and the other end is connected with the jacking nut; Said motor output end is connected with and connects cover, connects to put to be connected with slotting cutter.
Compared with prior art, the beneficial effect of the utility model is:
Realize the location through three alignment pins between a kind of 76000 tons of rudder blade keyways processing of the utility model special tooling, it and rudder blade, locating speed is fast; Easy for installation, horizontal guide rail and vertical guide rail all adopt rectangular guideway, have saved adjustment parts such as gag; Reduced the frock volume and weight, jacking leading screw and stretching leading screw can be realized the feed of vertical direction and horizontal direction respectively, and the utility model can directly be installed and used at the scene; Just accomplished the processing of keyway in more than one hour; Easy to operate, shorten process time greatly, effectively reduces production cost.
