The rotary milling fixture device is characterized by comprising a big-head-end three-jaw chuck and a small-head-end three-jaw chuck, wherein the big-head-end three-jaw chuck is connected with a main driving disk of a machine tool by a first transition disk, the small-head-head three-jaw chuck is connected with a tip of the machine tool by a second transition disk, a big head end and a small head end of the guide vane to be machined are respectively positioned and clamped by the big-head-end three-jaw chuck and the-small head-end three-jaw chuck, and a small head end part of the guide vane to be processed is tightly jacked up by the tip of the machine tool.
Description
Technical field
The present invention relates to fire the processing technique field of machine compressor guide vane, relate in particular to the frock technical field that adopts four axles or five axles revolution milling machine tool processing combustion machine compressor guide vane, be specially the rotary milling fixture device for the processing of compressor guide vane.
Background technology
The common two ends of combustion machine compressor guide vane are designed to the face of cylinder or taper seat, the middle part is the blade profile, because the blade profile is irregular curved surface, thereby the processing of blade profile usually adopts four axles or five axles revolution milling machine tool to carry out, and this just need to clamp benchmark with the face of cylinder at guide vane two ends or taper seat as the location by anchor clamps the guide vane clamping is being turned round on the milling machine tool.Existing clamping mechanism, the face of cylinder of guide vane stub end or taper seat are fixed on the lathe with the V-type positioning and clamping mechanism, the microcephaly holds the top location of adopting lathe to carry to hold out against, its shortcoming is: the V-type detent mechanism of blade stub end need to be special according to the face of cylinder or the taper seat size of blade stub end, cost is high, and its versatility is poor, need to dispose different V-type detent mechanisms for the guide vane processing of different model size; In addition, its little head end is directly held out against by the top location that lathe carries, only rely on the V-type detent mechanism of stub end to be connected with lathe master driving-disc, belong to single rotating band moving vane revolution and mill processing, along with the continuous change of length of blade size is large, the processing poor rigidity of blade causes the blade processing size unstable.
Summary of the invention
For the problems referred to above, the invention provides the rotary milling fixture device for compressor guide vane processing, it can solve, and the versatility that existing guide vane clamping mechanism exists is poor, blade processing poor rigidity and the unsettled problem of processing dimension.
Its technical scheme is such, it is characterized in that: it comprises that stub end scroll chuck and microcephaly hold scroll chuck, described stub end scroll chuck is connected with lathe master driving-disc by the First Transition dish, described microcephaly holds scroll chuck to pass through the second transition disc to be connected with lathe is top, the stub end of guide vane to be processed and microcephaly's end hold the scroll chuck location to clamp by described stub end scroll chuck, described microcephaly respectively, and the little cephalic par of described guide vane to be processed holds out against by described lathe is top.
It is further characterized in that:
The blade connecting end surface of described stub end scroll chuck is provided with the circumferential alignment pin of blade and sharf to alignment pin;
The scroll chuck connecting end surface of described First Transition dish also is provided with the circumferential alignment pin of the first chuck;
Described lathe is top to hold out against the little cephalic par of described guide vane to be processed after passing described the second transition disc;
The scroll chuck connecting end surface of described the second transition disc is provided with the circumferential alignment pin of the second chuck.
It further is characterised in that:
The both ends periphery of described guide vane to be processed is separately installed with snap ring, and described stub end scroll chuck, microcephaly hold scroll chuck by described snap ring described blade to be processed to be clamped respectively;
The outer peripheral face of described snap ring is the face of cylinder;
The inner peripheral surface of described snap ring is inner cylinder face or the inner conical surface that is complementary with guide vane two terminal circle cylinder to be processed or taper seat.
Compare with existing clamping mechanism, beneficial effect of the present invention is: the two ends of guide vane to be processed are respectively by standardized element scroll chuck clamping and positioning, scroll chuck is connected with lathe by transition disc, thereby its versatility is high, can satisfy the revolution of the guide vane of different size requirement and mill processing; And after the blade two ends all adopt the standardized element scroll chuck to clamp, process on the revolution lathe with the double driving mechanism dish of can packing into, thereby greatly increased the processing rigidity of blade, guaranteed the stability of processing dimension, and can the Effective Raise working (machining) efficiency; And the rotary freedom when the circumferential alignment pin of blade of the blade connecting end surface setting of stub end scroll chuck and sharf can limit guide vane clamping to be processed respectively to alignment pin, move axially the free degree, the effect of the rotary freedom when two circumferential alignment pins of chuck play respectively the corresponding scroll chuck of restriction and are connected with transition disc, guarantee the guide vane clamping precision, further guaranteed processing stability; Because guide vane two terminal circle cylinder or taper seat are the assembling position, its surface roughness is had relatively high expectations, thereby when clamping, in guide vane both ends periphery snap ring is installed first, and then clamp with scroll chuck location, snap ring can prevent effectively that scroll chuck from weighing guide vane two terminal circle cylinder or taper seat wounded when clamping; This, when guide vane to be processed two ends are taper seat, because inner peripheral surface and the guide vane to be processed two ends outer conical surface of snap ring are complementary, thereby the taper seat location can be changed into location, the face of cylinder, not only improved positioning accuracy, and can use the such standardized element of scroll chuck to position clamping, reduced the frock cost.
