Description

The slope profiling exemplar of multiple mark

Technical field the utility model relates to the profiling exemplar that uses on a kind of contouring machine.

Background technology is in forging process, and the roller that rolls that grinds on the ring rolls that encircles the operation use generally is consistent with its workpiece design angle.If the workpiece design angle is big, the angle that rolls roller rolls the just increase in proportion of axial force that roller bears also along with increase, when the taper hole angle value exceeds certain limit, is difficult to process qualified product; Particularly the taper hole angle is bigger, and workpiece taper hole diameter is less again, and two factors have limited the increase that rolls roller diameter again, usually fractures because of insufficient strength makes it.Therefore, when the workpiece design angle was big, the angle of forging had to be limited in certain limit, promptly reduces forging taper hole angle, and the increase that reduces to cause workpiece turning amount of taper hole angle, promptly forging has stayed the processing capacity of twice turning fully to turning processing.Its structure of profiling exemplar of using on the existing copying lathe mainly is: be located at the two top with the fixed head horizontal location of fixed head two ends, on this fixed head, be fixed with copying template by screw, the end limit that this copying template extends downwards is a hypotenuse, and its gradient is identical with the workpiece tapering.Above-mentioned copying template is fixed, therefore lathe can only be to the turning of workpiece taper hole once, and this moment, workpiece was not worked into qualified size, has to workpiece unloaded be transported to another lathe and carry out once more clamping, turning, when second circulation end automatically, workpiece just is worked into qualified size.Because profiling exemplar track is single, causes above-mentioned processing method to have following shortcoming: 1. twice installation of workpiece location all is benchmark with the black skin, because the black skin precision is low, makes the axiality and the end face run-out of the clamping workpiece second time all bigger.Location benchmark disunity, the depth of cut difference when causing turning for the second time is bigger, and the cutter unbalance stress has influenced the form and position tolerance and the dimensional accuracy of product.2. increased the once mounting workpiece, unloaded workpiece, tool axis is to F.F., rewind down and time of putting workpiece, both increased labour intensity, reduced production efficiency, many again consuming electric powers increase cost.

The summary of the invention the purpose of this utility model is to provide a kind of to carry out a clamping workpiece and just can finish the multiple mark slope profiling exemplar that it is carried out twice turning.The utility model mainly includes: slip profiling exemplar, electromagnet, amount of movement are adjusted nut, spring, elastic force adjustment nut, slip profiling exemplar axle, not little axle of magnetic conduction and tubular distance piece.Wherein, profiling exemplar axle by solid shafting, cylindrical suction piece and not the little axle of magnetic conduction constitute.The cylindrical suction piece that is connected as a single entity with solid shafting is provided with the axial screw with its coaxial line, and itself and the little axle of the not magnetic conduction that does not reduce electromagnet magnetic force threaded one end are connected.The two ends of this exemplar axle be solid shafting one end and not the little axle of magnetic conduction one end be respectively equipped with conical bore, its with the original profiling carriage of lathe on two top corresponding, and profiling exemplar axle horizontal is fixed by them.Electromagnet is made up of metallic plate and parcel electromagnet coil body within it, and the diameter of this electromagnet central through hole divides two sections of sizes, and big bore dia is corresponding with the diameter that the exemplar axle is inhaled the piece part, and hole diameter is with the little shaft diameter of magnetic conduction is not corresponding.Above-mentioned exemplar axle establish inhale piece and not an end of the little axle of magnetic conduction be inserted in the electromagnet central through hole, the little shaft extension of magnetic conduction is not provided with screw thread to the free end of electromagnet outside, it is adjusted nut with shift amount and is meshed, the amount of movement of the relative position decision electromagnet of this nut on the little axle of magnetic conduction not.For making above-mentioned nut accurate positioning, be preferably on its sidewall and establish screw, be provided with screw in it.Outside in exemplar axle solid shafting part is with the tubular interval sleeve pipe, and the one end is stuck in outside the electromagnet through hole, and the other end is adjacent with slip profiling exemplar.Establish the central through hole corresponding in this profiling exemplar with the exemplar axle.This is enclosed within the profiling exemplar peripheral hardware slope on the exemplar axle solid shafting part, its form can have multiple, require the identical truncated cone of tapering as tapering with workpiece, the spindle that needs the profiling exemplar to form by two truncateds cone for the processing special workpiece, the profile of above-mentioned profiling exemplar can also be by by the pipe of central through hole be fixed on that swash plate on its outer peripheral face forms, the swash plate that this plate face is parallel with the pipe bus, its end limit of extending the downwards identical hypotenuse of tapering that to be gradient require with workpiece.For prevent that exemplar from rotating when mobile, in the pipe part of this exemplar, establish and the corresponding guide groove of exemplar axle epirelief key, the other end of above-mentioned profiling exemplar is adjacent with the spring that is enclosed within exemplar axle solid shafting part, the other end of this spring withstands on elastic force and adjusts on the nut, and this nut is meshed with the external screw thread of exemplar axle solid shafting part.Loosening for preventing it, be preferably in this nut sidewall and be provided with screw, establish trip bolt in it.The course of work of the present utility model is as follows; During lathe work, under the control of electrical equipment and hydraulic part, move axially oil cylinder and drag tool axis to F.F..When cutter accelerates during near workpiece into to the worker advances, meanwhile Hydrawlic Slave System is handled radial oil cylinders and is driven on the radial tool post and move, and the contact of Hydrawlic Slave System is contacted with the exemplar slope.Electromagnet in the profiling exemplar also gets when F.F. is exchanged work at tool axis.Under the effect of magnetic force, promote the profiling exemplar to spring one side slip by tubular distance piece, and with the spring compression, till the suction piece operative tip of exemplar axle is pull-in on protruding the closing of electromagnet central through hole.This process is finished before the cutter contact workpiece, so lathe carries out the turning first time in the cutter radial position of first limiting trajectory control of this profiling exemplar.When turning to the workpiece processing terminal, when lathe tool retreated to workpiece processing top, knife rest began for the second time axially that the worker advances, electromagnet outage meanwhile, the profiling exemplar is adjusted nut one side slip together with tubular distance piece, electromagnet to amount of movement under the effect of spring.Till when electromagnet and displacement are adjusted nut and are close to.This moment, lathe began to carry out the turning second time in the cutter radial position of second limiting trajectory control of this profiling exemplar.When turning was to the workpiece processing terminal once more, knife rest retreated to original position, a circulation end automatically, and workpiece is machined into qualified size.The utility model has following advantage compared to existing technology: because electromagnet can order about the profiling exemplar and move at its axial limiting, its bootable copying contact radial position that contacts with the slope changes, radial position until the guiding machine tool also changes, it is the radial seat cursor position that the axial internal clearance on exemplar slope has changed the copying contact that is in contact with it, until the radial seat cursor position that has changed lathe tool, reach the requirement that changes workpiece size at last, just a profiling exemplar has two duties, thereby has realized the variation of profiling exemplar track.Workpiece is installed and once can be finished twice cutting automatically like this, thereby with the installation of workpiece, unload, knife rest F.F., knife rest rewind down and workpiece put each and reduce once, this has not only alleviated working strength of workers, has improved production efficiency, and has reduced energy consumption again, has reduced cost.More importantly be, one time clamping workpiece makes the location benchmark of the first time and turning for the second time constant, and the depth of cut is even when having guaranteed turning for the second time, has improved the form and position tolerance and the dimensional tolerance precision of workpiece.
