Description
Technical field
The present invention relates to frock technical field, particularly a kind of for front from the assembled tool of plate in locomotive buffer unit.
Background technology
The front a kind of part belonged to from plate locomotive buffer unit, is locomotive operation traction and the important stress part of braking buffering.
Before belong to cuboid orthodrome special-shaped forge parts, range of work width from the blank of plate, belong to interrupted cut, at ordinary times produce mostly be the scale that small lot is multiple batches of.It is move radially first with the Cutting tool installation manner dish on boring machine facing head to this front traditional processing mode from plate, after driving boring cutter centering blank center of rotation thereon, then heavy boring, right boring orthodrome.
In actual production process, this tradition processing mode also exists following weak point:
1, when centering blank center of rotation, labor intensity is high, and centering efficiency is low.When machining blanks part, tool wear is fast, frequent reconditioning, install again after repairing a die, to cutter and boring time, it is necessary to the centering centre of gyration again；After processing one batch of part, once there be the situation of boring machine tool changing, the Cutting tool installation manner dish centre of gyration also can change, under processing, the repetition consuming job adjusting cutter and centering blank center of rotation during batch part, will be faced again.Therefore, the action repeating centering blank center of rotation has had a strong impact on front from the working (machining) efficiency of plate.
2, the cutter of boring machine is typically all Integral forge type cutter, after tool wear, it is necessary to again after dismounting could grinding, the difficulty of cutter is big, efficiency is low, therefore, seem the process time after product flaw detection particularly nervous.And at processing site, though there being other boring machines, but the product also having other boring cycle longer waits for processing, processing tasks is very saturated, therefore to arrange and to coordinate extremely difficult.
In consideration of it, be highly desirable to the front processing method from plate or instrument are improved, to improve working (machining) efficiency.
Summary of the invention
The goal of the invention of the present invention is in that: for above-mentioned Problems existing, it is provided that a kind of for front from the assembled tool of plate in locomotive buffer unit.
The technical solution used in the present invention is such that
The first scheme: a kind of for front from the assembled tool of plate in locomotive buffer unit, including cutter rotary apparatus, positioning clamping device two large divisions；Described cutter rotary apparatus includes drive mandrel, Cutting tool installation manner dish, described Cutting tool installation manner dish is for ellipse and is fixedly mounted in drive mandrel, the major axis two ends of Cutting tool installation manner dish are respectively mounted rough turn cutter and shaving tool, and the radius of turn of rough turn cutter is less than the radius of turn of shaving tool and staggers in the axial direction；Described positioning clamping device includes positioning body, has for compressing the front pressing plate from plate and fishbolt on the left of positioning body, and positioning body right boss is fixedly mounted on the knife rest of lathe；The front arc surface from plate is just rotated by described rough turn cutter and shaving tool.
First scheme: this programme increases improvements further in the first scheme, and described positioning clamping device is provided above suspender.
Suspender in preferred first scheme, described suspender includes inverted U fixture, clamping screw, inverted U clamp top arranges suspension ring, the positioning body top of described positioning clamping device arranges clip groove, installing from the inverted U fixture of plate before being easy to handling and installing, inverted U fixture is locked front from plate by clamping screw.
Above-mentioned suspender is further improved, and described clamping screw afterbody vertically connects set lever, in order to locking.
Cutting tool installation manner dish in two schemes is carried out preferably, described Cutting tool installation manner dish major axis one end arranges rough turn cutter mounting groove and cutter hold-down apertures, rough turn cutter is installed in rough turn cutter mounting groove and is fixed with in cutter hold-down bolt screw-in cutter hold-down apertures, the Cutting tool installation manner dish major axis other end arranges shaving tool mounting groove and cutter hold-down apertures, installs shaving tool and be fixed with in cutter hold-down bolt screw-in cutter hold-down apertures in shaving tool mounting groove；The short axle two ends of Cutting tool installation manner dish are offered mounting disc location Kong Bingyong mounting disc bolt and are realized the location between Cutting tool installation manner dish and drive mandrel.
Positioning body in two schemes is carried out preferably, described positioning body left bottom arranges front from plate erecting bed, before from plate erecting bed vertical and rear side adjustment screw is set, positioning table top is arranged is easy to the clip groove of clamping screw traverse, it is simple to processing different specification size front from plate or other need the part of boring circular arc.
Such scheme is carried out preferably, the boss on the right side of positioning body is loaded in the cutter platform groove of knife rest, utilize the bolt on knife rest to be locked by the boss of positioning body.
Such scheme is carried out preferably, rough turn cutter on described Cutting tool installation manner dish and be detachably provided with the rough turn blade of numerical control and finishing tool blade on shaving tool.Rough turn cutter and shaving tool all adopt knife bar and the box-like installation form of set of blades, need not dismantle knife bar after such blade abrasion.Blade adopts conventional digital cuttings, quick for installation, and positioning precision is high, it is possible to accomplish that sizing is processed.When blade abrasion needs to change, it is only necessary to the blade that quick-replaceable precision is higher, it is not necessary to dismantle knife bar and carry out, again to cutter, eliminating the cutter time.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, being transplanted on lathe of boring operation innovation boring machine undertaken；
2, change traditional knife rest and fill the processing mode of cutter, main shaft dress workpiece, but be fixed on the knife rest of lathe with knife rest from plate and vertically move by front and laterally adjust motion, after the centering Template Location radius of gyration, utilize chuck rotation mandrel to rotate, do turning campaign by the rough turn cutter on carry its tools rotary apparatus and shaving tool；
3, the axile displacement of two cutters and radially different rotating diameter are utilized, disposable complete front from the rough turn of plate circular arc with finish turning operation, substantially increase machining accuracy and the efficiency of product, simultaneously the Function of boring machine in other part processing that working (machining) efficiency is higher.
