The invention discloses a copy turning device for an arc shaped inner cavity of a water jacket in a round billet crystallizer, which comprises a headstock chuck, a tailstock center and an apron, wherein the apron is provided with an intermediate splint. The device is characterized in that both sides of the intermediate splint are fixed with brackets, the brackets are provided with jackscrew rods,and workpiecs are clamped in the brackets through pressure shoes; a tool pan is positioned in the middle of the workpiece and is arranged on a cutter spindle, and a nut is fastened by a tool pan, oneend of the cutter spindle is locked on the chuck, and the other end of the cutter spindle is pressed against the tailstock center; the non-operation side of the intermediate splint is provided with aconnecting plate; one end of the connecting plate is connected with the intermediate splint, while the other end is connected with a profiling mechanism; the profiling mechanism is fixedly connected with the non-operation side of a lathe body through a framework support; the inside of a profiling framework is provided with a profiling notch, and the intermediate splint is driven to perform radialrestrained motion through a roll wheel and a roll wheel shaft of the roll wheel; the intermediate splint is driven by the apron to perform axial movement; and the cutter spindle is driven by the headstock chuck to rotate.
Description
Technical field
The present invention relates to the lathe for machining or the truning fixture of special workpiece, relate in particular to the copying device feeding and have the lathe or the truning fixture of swivelling tool-holder.
Background technology
Crystallizer water jacket is parts in the crystallizer assembly, it is set in the outside of crystallizer copper pipe and keeps certain uniform gap with the gabarit of copper pipe, form a fixing water seam, guarantee that the cycle of higher pressure cooling water passes through equably, make crystallizer copper pipe absorb the heat of molten steel in the copper pipe equably, so that make molten steel in condensation process, form the base shell of equal thickness.In view of the jacket pipe and all non-straight length of copper pipe of crystallizer, they are the bend pipes with certain radian, so difficulty of processing is very big.Though varied about the processing method of crystallizer water jacket both at home and abroad, be to adopt Digit Control Machine Tool on cylinder stainless steel pipe, to process method to realize basically with different circular sections bus.The shortcoming of this method is conspicuous, mainly be the process-cycle long, cost is high, machining accuracy is low and yielding.
Summary of the invention
Proposition of the present invention is intended to overcome the shortcoming of existing processing method, and the truning fixture that has designed a kind of copying device feeding and had a swivelling tool-holder is realized the turning processing of this special workpiece.
Technical solution of the present invention is achieved in that
A kind of profile turning device of round mold inner water sleeve arc inner chamber, comprise on headstock chuck, tailstock centre and slip crate, the slip crate supporting plate in the band, the both sides of supporting plate are fixed with carriage in it is characterized in that, the jackscrew bar is arranged on the carriage, its front end connects pressure shoes, by pressure shoes workpiece is fixed in carriage; Cutterhead is arranged in the workpiece, and cutterhead is sleeved on the cutter spindle, and fastening by the cutterhead locking nut; The not operation side of supporting plate is won in succession in described, the one end is fixedlyed connected with middle supporting plate, the other end is connected with pattern mechanism, described pattern mechanism comprises template, running roller and rolling axle, the profiling notch is arranged in the described template, running roller is arranged in the profiling notch, and does radially constrained motion by supporting plate in rolling axle and the connecting plate drive; Supporting plate moves axially under the drive of slip crate in described; Described cutter spindle is then driven by the headstock chuck and rotates.
The profiling notch is arranged on the described template, and it is shaped as arc, taper or parabola shaped.
Compared with prior art, advantage of the present invention is conspicuous, mainly shows: simple in structure, easy to operate, machining accuracy is high, improved effect.

In the drawings: 1, headstock chuck 2, cutter spindle 3, workpiece 4, carriage 5, jackscrew bar 6, pressure shoes 7, lathe tool 8, cutterhead 9, cutterhead locking nut 10, win 11 in succession, on the middle supporting plate 12 on the slip crate, tailstock centre 13, falsework 14, template 15, running roller 16, rolling axle 17, slip crate in dovetail guide 18, the slip crate of supporting plate.
The specific embodiment
The processing unit (plant) of the round mold inner water sleeve arc inner chamber shown in Fig. 1～2.This device is a kind of truning fixture that is used to process round mold inner water sleeve arc inner chamber based on engine lathe, removing knife rest behind small tool and the carriage turn-screw by engine lathe partly transforms and forms, its structure comprises headstock chuck 1, tailstock centre 12 and slip crate 18, supporting plate 11 in having on the described slip crate, the two sides of supporting plate 11 are fixed with carriage 4 in it is characterized in that, jackscrew bar 5 is arranged on the carriage 4, and its front end connects pressure shoes 6, by this pressure shoes workpiece 3 is fixed in carriage 4; Cutterhead 8 is arranged in the workpiece 3, and cutterhead 8 is on cutter spindle 2, and it is fastening to pass through cutterhead locking nut 9, lathe tool 7 is housed on the cutterhead 8, and lathe tool can be adjusted flexible in cutterhead, realizes the adjustment of bite, one end of described cutter spindle 2 is clamped on the headstock chuck 1, and the other end is then held out against by tailstock centre 12; The not operation side of supporting plate wins 10 in succession in described, and the one end is fixedlyed connected with middle supporting plate 11, and the other end then is connected with pattern mechanism, there is template 14 in this mechanism, running roller 15 and rolling axle 16, described template 14 is fixedlyed connected with falsework 13, and falsework 13 is fixed on the not operation side of lathe bed; In the described template 14 the profiling notch is arranged, running roller 15 is arranged in the profiling notch, and does radially constrained motion by supporting plate 11 in the rolling axle 16 and 10 drives of winning in succession; Supporting plate 11 axially moves under the drive of slip crate 18 in described; 2 of described cutter spindles are driven by headstock chuck 1 and rotate.The profiling notch of described template 14, its shape can be the slick and sly arcs continuously of arc, multistage.Be used to realize the processing of arc, cylindrical cavity, curved cylindrical cavity.
Below in conjunction with embodiment process of the present invention is described further.As shown in Figure 3, the relative position of visible workpiece, cutter and pattern mechanism.To be processed is installed on the carriage, and the left side of workpiece is marked the tool setting line on request, press line to good cutter after, cut.Workpiece is moved to the left with slip crate and moves radially along the notch on the template, and the cutter rotation realizes cutting.Because cutting output can not once be finished, beginning is to have cut the two ends of workpiece inner arc side and the mid portion of outer arc side earlier; Adjust the overhang of cutter successively, both full tube cavity can be lathed the curved circular cylinder intracavity.
