Description

Radius rod sphere copying apparatus
Technical field
The invention belongs to machine tool accessories field, refers to copying apparatus during a kind of turning large spherical surface, specifically relates to And be a kind of radius rod sphere copying apparatus.
Background technology
General during super-huge accessory turning be lathe, an i.e. worm gear drive mechanism of subsidiary engine come jointly complete using a main frame Into processing tasks, lathe main will complete cutter clamping and feed feeding, and worm gear drive mechanism mainly completes clamping workpiece and rotation Drive.General super-huge spherical parts, diameter reach several meters even more than 10 meters, at present, to adopting the turning of this kind of part more Pattern carries out copying, and the pattern process-cycle length of its turning, difficulty are big, costly, and during use, pattern clamping also compares It is difficult.This kind of part consumption is few in addition, and the sphere processing pattern of different-diameter can not be general, there may come a time when to process one Individual part pattern just loses use value.So, super-huge spherical parts copying is carried out using pattern and causes cost of parts Drastically raise.In this regard, designing a kind of easy processing, low cost, the large spherical surface part processing copying device of highly versatile has very much must Will.
The content of the invention
It is an object of the invention to overcome the shortcomings of zero ball profile tracer processing unit (plant) of existing large spherical surface, propose a kind of easy Processing, low cost, the large spherical surface part processing radius rod sphere copying apparatus of highly versatile.
The technical scheme for realizing above-mentioned purpose is:A kind of radius rod sphere copying apparatus, including slide, slide bar knife Frame, coupling bar, radius rod and rotating handle, it is characterised in that the slide is fixed on the big palette of big lathe bed, and slide is provided with Slide bar knife rest, slide bar knife rest one end are provided with turning knife, and the other end is rigidly connected with coupling bar, the other end and radius rod of coupling bar One end be hinged, the effective length of radius rod is equal to workpiece spherical radius, and the other end of radius rod is rigidly attached on rotating handle, Rotating handle is hinged on the little supporting plate of little lathe bed.
Easy processing of the present invention, expense are low, highly versatile, convenient mounting and clamping, using the element precision height of the device processing, cost It is low, it is the preferable copying apparatus of large spherical surface part.
Description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the planar structure schematic diagram when present invention is installed, adjusted.
In figure:1. base, 2. big lathe bed, 201. leading screws, 202. big palettes, 203. control cranks, 3. workpiece, 4. worm gear drive Motivation structure, 401. mandrels, 5. slide bar knife rest, 501. turning knives, 6. coupling bar, 7. rotating handle, 8. radius rod, 9. little lathe bed, 901. little supporting plates, 10. slide.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention includes slide 10, slide bar knife rest 5, coupling bar 6, rotating handle 7 and radius rod 8;Big lathe bed 2nd, little lathe bed 9 and worm gear drive mechanism 4 are arranged on the base 1 with T-slot, to adjust and fixation.Characterized in that, institute State slide 10 to be fixed on the big palette 201 of big lathe bed 2, by controlling control crank 203, leading screw 201 will drive big palette 202 Advance, fall back or speed change;Slide 10 is provided with slide bar knife rest 5, and 5 one end of slide bar knife rest is provided with turning knife 501, turning knife 501 Move along the lathe bed direction of big lathe bed 2 with big palette 202 under the drive of slide 10, complete length feed;Slide bar knife rest 5 it is another One end is rigidly connected with coupling bar 6, and the other end and one end of radius rod 8 of coupling bar 6 are hinged, effective length of radius rod 8 etc. In 3 spherical radius of workpiece, the other end of radius rod 8 is rigidly attached on rotating handle 7, and rotating handle 7 is hinged on and is fixed on little lathe bed 9 Little supporting plate 901 on, so, during 202 lengthwise movement of big palette, the pin joint around rotating handle 7 is rotated by radius rod 8, and is passed through Coupling bar 6 forces slide bar knife rest 5 to slide in slide 10, turning knife 501 is moved along the direction vertical with 2 lathe bed of big lathe bed, Turning knife 501 moves synthesis along the lathe bed direction of big lathe bed 2 and two, the direction vertical with 2 lathe bed of big lathe bed so that turning knife The movement locus AB camber lines and coupling bar 6 of 501 points of a knife is radius equal to workpiece 3 with the central rotation track that is hinged of radius rod 8 The circular arc line of spherical radius, i.e. geometric locus are profiling curve;Meanwhile, the workpiece 3 on mandrel 401 is mounted in worm gear drive mechanism Rotate under 4 driving, complete the circle-feeding of turning, then the external surface after part processing is sphere.
As shown in Fig. 2 before processing, adjust the position of worm gear drive mechanism 4, make the sphere AB on workpiece 3 it is profound substantially with The guide rail parallel of big lathe bed 2, so, the allowance on workpiece 3 is that actual Lathe quantity will be than more uniform.Meanwhile, by turning knife 501 point of a knife moves on to position of the and distance parallel with 3 basal plane C of workpiece for plane O-O1 of a, and a is the distance of the centre of sphere and basal plane C, The position of little lathe bed 9 and little supporting plate 901 is adjusted again, makes radius rod 8 parallel with basal plane C, finally fix and lock worm-gear driven machine Structure 4, little lathe bed 9 and little supporting plate 901, so just can guarantee that the centre of sphere and turning knife all the time with workpiece 3 of radius rod 8 in process 501 point of a knife line is parallel, so as to ensure the correct of spherical surface position.
In the present embodiment, by the effective length for adjusting slide bar knife rest 5 and radius rod 8, the sphere of different radii can be processed, Copying device versatility is high.Effective length when being worked due to radius rod 8 keeps constant, so the accessory size after processing is accurate Really, high precision.Workpiece 3 is the device installation site of a processing spherical outside surface with radius rod 8 respectively positioned at the both sides of big lathe bed 2, During working inner sphere, workpiece 3 and radius rod 8 are arranged on into the same side of big lathe bed 2.
