Description
Technical field
The utility model belongs to Machining Technology field, relates to concretely a kind of auxiliary mould of processing low-angle oblique circular cylinder class thin-walled parts.
Background technology
In the machine components of the industries such as space flight, aviation, oil drilling, there is low-angle oblique circular cylinder class thin-walled parts quite a lot, as shown in Figure 1.The feature of this class part is: inwall is that radius is the arc disc of R, Milling Process and one end band gradient X ° for cylindrical, and the step with gradient one end is correspondingly also with gradient X °.Different according to residing condition of work, the material of this class part has diversity, has to nonmetal from high temperature alloy.At present, the processing of this class part is generally adopted to milling or spark machined, but spark machined only limits to metal.
Wear gradiently due to such part one end, the crossing formation ellipse on its step and inclined-plane, while using Milling Process, carry out angle clearly, must avoid machining stress excessive, just must select the milling cutter of minor diameter, and cutter also will be walked three-dimensional path.The metal removal rate of so little cutter has just reduced, long processing time, and the utilization ratio of lathe is low, has also increased the expense of cutter simultaneously.
The spark machined that only limits to metal is to come deposite metal by electric discharge, and working (machining) efficiency is lower, and production cost is higher, conventionally also has the remelted layer of discharge generation and fire check phenomenon to occur, and has affected crudy.
Prior art is all to carry out entirety processing to the part of this shape, and process is very complicated.Taking milling tool as example, in process, part is motionless, milling cutter parallel inclined-plane process round and round, in such motion process, cutter does four kinds of motions, rotates, carries out circular motion, repeatedly moves, moves upward in the footpath of part to be processed at part axial to be processed around the center of part to be processed around Pivot Point Center.Because the motion of cutter is so complicated, consuming time also just very long, working (machining) efficiency is very low.And in the utility model, through after this division, to straight cylinder section with tiltedly when cylindrical section separate machined, low-angle oblique circular cylinder class thin-walled parts to be processed all can High Rotation Speed, greatly shorten process time, working (machining) efficiency is greatly improved.Because such processing mode is not occur in prior art the inside, do not belong to the conventional means of the art yet, be therefore non-obvious, there is outstanding substantive distinguishing features.
2, low-angle oblique circular cylinder class thin-walled parts is arranged on clamp body at a slant, has changed the processing pivot of part, oval inclined-plane is become to the revolving body of available lathe processing, in the time of the oblique cylindrical section of processing, part can carry out High Rotation Speed.
Such scheme is further improved, and when low to the tolerance of low-angle oblique circular cylinder class thin-walled parts, it is circular that the part of Internal hole positioning mandrel coordinates section cross section.Because gradient is very little, the ellipse of step end face approaches the shape of circle very much, therefore, can directly be approximated to circle and process, even if the part wall thickness processing is somewhat inhomogeneous, but as long as in the scope allowing in tolerance, also calculates qualified products.
Such scheme is further improved, when high to the tolerance of low-angle oblique circular cylinder class thin-walled parts, it is oval that the part of Internal hole positioning mandrel coordinates section cross section, and from the step end face direction of low-angle oblique circular cylinder class thin-walled parts, low-angle oblique circular cylinder class thin-walled parts is supportted circular.In the time that tolerance is high, the ellipse of step end face just can not be approximated to circle and process, otherwise the even problem of part wall unevenness can have influence on product quality.Therefore, must first use Internal hole positioning mandrel by circular the step end face support of part, and then allow part carry out gyration processing around the circle core shaft of step end face, ensure that wall thickness is even.
In theory, in order to reduce dimensional discrepancy, no matter tolerance how, all should support step end face circular rear reprocessing.Lathe tool is processed exactly on a disc like this, and wall thickness uniformity coefficient is high.If the gradient of oblique circular cylinder section is little, and tolerance is not high, ellipsoid can be approximated to disc yet, can reduce like this processing cost of Internal hole positioning mandrel.
Such scheme is further improved, the step sidewall of described low-angle oblique circular cylinder class thin-walled parts is provided with locating notch, on clamp body end face, be provided with the dowel hole corresponding with locating notch, realize the location between low-angle oblique circular cylinder class thin-walled parts and clamp body by an alignment pin insertion locating notch and dowel hole.By locating notch and dowel hole, can realize quick location.
Utility model content
The purpose of this utility model is: for the problem of above-mentioned existence, provide a kind of auxiliary mould of easy and simple to handle, processing low-angle oblique circular cylinder class thin-walled parts that production efficiency is high, be specially adapted to the smaller oblique circular cylinder class thin-walled parts of gradient.
The technical solution adopted in the utility model is such:
A kind of auxiliary mould of processing low-angle oblique circular cylinder class thin-walled parts, comprise clamp body, Internal hole positioning mandrel and nut sleeve, locating hole and location counterbore are set on described clamp body, the center line of locating hole and location counterbore is through clamp body end face center and become X ° of angle with the center line of clamp body, described Internal hole positioning mandrel is divided into positioning section, part coordinates section and thread segment and center to establish screw hole, in the location counterbore of positioning section insertion clamp body and by compressing SOC.HD. cap screw, clamp body and Internal hole positioning mandrel are fixed through screwing in again in locating hole positioning section from screw hole, part coordinates section surface to mate with the endoporus of low-angle oblique circular cylinder class thin-walled parts to be processed, nut sleeve is threaded on thread segment and by end face low-angle oblique circular cylinder class thin-walled parts is pushed against on Internal hole positioning mandrel.
The main improvement of above-mentioned auxiliary mould is that Internal hole positioning mandrel is to insert in clamp body and position at a slant, after having changed the pivot of part, then cutter is motionless, part high speed rotating, the relative part of cutter moves in a circle, but be in fact to process round and round along inclined-plane, forms of motion is simple, and process velocity is fast.
The improvement of such scheme mainly contains following 3 points:
1, low-angle oblique circular cylinder class thin-walled parts outer surface to be processed is divided into straight cylinder section and oblique cylindrical section two parts, then separately processes.
