Description
Technical field
The utility model relates to a kind of machining tool fixture, more specifically to a kind of arc surface machining tool fixture.
Background technology
In axle extend through flow type hydraulic turbine, unit overcurrent part water distributor is made up of ring, stator outer shroud, transmission mechanism etc. in 16 stators, the stator.Stator is contained between the interior ring of stator, the outer shroud.Adjusting and emergency shutdown are mainly realized by regulating guide vane opening during hydraulic turbine overcurrent.In the unit design, ring, outer shroud all are spherical shapes in the stator, and this will the differentiate leaf must be the arc surface shape, could guarantee that stator rotates flexibly, not be stuck.In the prior art, be not exclusively used in tubular stator arc surface machining tool fixture, realize that stator cambered surface processing must carry out in main equipment, therefore investment is big, and versatility is little.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of simple in structure, small investment, the tubular stator arc surface machining tool fixture that versatility is good.
The purpose of this utility model is achieved by following technical scheme: a kind of tubular stator arc surface machining tool fixture, comprise two parts, first comprises master plate and fixation clip, one side of master plate is connected with one side of fixation clip by bolt, the another side of master plate is equipped with support bar, second portion comprises knife bar, locating piece, the cutter box, spring and roller bearing, knife bar is the cutter head folder on one side, the cutter head folder is by the bolting cutter, the knife bar another side is a locating clip, roller bearing is installed on the locating clip, the intermediary outside of knife bar is the cutter box, and an end of spring is installed on the knife bar, and the other end of spring is fixed on the cutter box, knife bar is connected with the cutter box by spring, on one side the cutter box is equipped with locating piece; The master plate of first contacts with knife bar by roller bearing.
In process, earlier the fixation clip in the first of the present utility model is fixed on the tail top of horizontal lathe, thereby first of the present utility model is installed on the lathe; Then the locating piece on the second portion is fixed on the knife rest of lathe, cutter box and knife bar are finished the processing of stator arc surface along with inside and outside the moving of lathe.For the accuracy that guarantees the stator arc surface with reduce friction, adopt roller bearing to contact on the locating clip, thereby make knife bar slip neatly on master plate with master plate.
The processing technology scheme is as follows:
1. the lifting workpiece is adorned fixation clip, master plate, installs cutter box and locating piece, adjusts the position of roller bearing, locks fixation clip and locating piece, adjusts the bolt of cutter head folder.
2. utilize special-purpose outer arc cutter processing stator external arc earlier, adjust the turning amount, comply with figure processing cambered surface to the figure paper size;
3. according to last step, utilize special-purpose inner arc cutter processing stator inner arc surface to the figure paper size.
This frock clamp is simple to operate, the machining accuracy height, and practicality is good; When the axle extend through flow type hydraulic turbine stator circular arc of the various model specifications of processing, only need to change master plate and get final product, versatility is good.
The beneficial effects of the utility model are the processing that has realized the stator arc surface, and the machining accuracy height does not take main equipment, small investment, and versatility is good.
