Abstract
The utility model relates to a kind of split type forming cutter of the processing step hole transition conical surface, the dovetail groove matched with stepped hole is opened in the middle of cutter holder, blade is arranged in the cutter groove of cutter holder both sides, the adjustment screw of adjustable blade position is provided with at the bottom of dovetail groove, there is the housing screw fastening to blade cutter groove side, two side blade installation directions are contrary, and blade respectively upward down.The utility model is inserted in the boring head tool bore that tapering matches, drive into macropore conical surface starting point from macropore port, complete large aperture transition cone face process by long feed.The utility model cutter holder and blade adopt split type, and blade can carry out adjusting and changing, can through repeatedly repeatedly using after sharpening; Carried out the tapering number of degrees of adjustable blade by the adjustment screw of the large small end of adjustment cutter holder, ensure that it is consistent with the workpiece drawing endoporus transition conical surface number of degrees; Housing screw is fastening to blade; The dovetail groove of cutter holder, alleviates weight, is convenient to the installation of adjustment screw.Cutter holder is reusable, adjustable or replacing after breaks down.
Description
Technical field
The utility model relates to the split type forming cutter of the processing step hole transition conical surface.
Background technology
The draw ratio of marine shafting is generally greater than 80, and in it, hole machined is a difficult problem always, a deep hole machining difficult problem especially for the special transition conical surface when endoporus is stepped hole version.
When lathe is processed the conical surface, by vertical and horizontal feed simultaneously, can easyly realize.But because the axle system endoporus draw ratio of deep hole machining is comparatively large, if use lathe process, vibration force and " cutter relieving " phenomenon can be produced when turning, have a strong impact on the crudy of part.In order to address these problems, the applicant adopts the process of carrying out processing on deep hole drilling and boring machine.Because deep hole working machine does not possess function of crossing feed, therefore, process the conical surface time, can only use forming-tool process and the size of forming-tool must be consistent with the size at part position to be processed, just can guarantee that accessory size meets the requirements.
During the forming-tool before designed, employing be use integral knife blade structure, make blade size consistent with accessory size, and when length feed, the strict depth dimensions controlling cutter feed, guarantees accurate to dimension with this kind of processing method.Therefore, this blade must be completely the same with the tapering sharpening of the product transition conical surface, and both sides cutting edge wants full symmetric, and cutter makes wastes time and energy.Once cutter in sharpening angle of arrival error, then can directly scrap.Meanwhile, in use blade cutting edge is once have damage or serious wear, and whole blade is discarded because size diminishes, and more must renew cutter.Therefore monolithic molding cutter makes complicated, and can not reuse that to result in the cost of charp tool high.
Integral-structure type forming-tool, selects high-speed steel material blade, and with being laser-cut into the shape consistent with part conical surface size, then anterior angle, the relief angle of sharpening cutter, guarantee excellent cutting performance.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aims to provide a kind of difficult problem that can solve the deep hole machining large aperture transition conical surface, can repeatedly use, and effectively reduces cutter expense, makes simple, the split type forming cutter of the processing step hole transition conical surface easy to adjust.
The implementation of the utility model object is, the split type forming cutter of the processing step hole transition conical surface, the dovetail groove matched with stepped hole is opened in the middle of cutter holder, blade is arranged in the cutter groove of cutter holder both sides, be provided with the adjustment screw of adjustable blade position at the bottom of dovetail groove, there is the housing screw fastening to blade cutter groove side, and cutter holder two side blade installation direction is contrary, upward, side blade down for side blade.
The utility model is inserted in the tool bore of the boring head that tapering matches, drive forming-tool into macropore conical surface starting point from macropore port, complete large aperture transition cone face process by long feed.Cutter holder of the present utility model and blade adopt split-type structural, and blade can carry out adjusting and changing, therefore can through repeatedly repeatedly using after sharpening; The adjustment screw reaching small end by adjusting cutter holder carrys out the tapering number of degrees of adjustable blade, ensures that it is consistent with the workpiece drawing endoporus transition conical surface number of degrees; Fastening to blade with housing screw; Dovetail groove in the middle of cutter holder, had both alleviated cutter holder weight, had been convenient to again the installation of adjustment screw.Cutter holder is reusable, adjustable or replacing after breaks down.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation,
Fig. 2 be the A-A of Fig. 1 to figure,
Fig. 3 is the B direction view of Fig. 1,
Fig. 4 is the state diagram of the utility model machining.
Detailed description of the invention
With reference to the accompanying drawings in detail the utility model is described in detail.
With reference to Fig. 1,2,3, blade 4 is arranged in the cutter groove of cutter holder 1 both sides, and cutter bottom land is provided with the adjustment screw 3 of adjustable blade position, and there is the housing screw 2 fastening to blade cutter groove side.Cutter holder two side blade installation direction is contrary, and side blade is down (see Fig. 3) upward for side blade.At least be provided with two at the bottom of each dovetail groove to the adjustment screw 3 regulating blade position, cutter groove side has two at least to the housing screw 2 fastening to blade.
For same specification cutter hub of the present utility model, the diameter dimension variable ± 10mm of its cutter hub concentric reducer.Blade 4 according to cutting material characteristic, choose reasonable blade material.
Using method of the present utility model:
Loaded by blade 4 in two side tool grooves of cutter holder 1 (see Fig. 1), note the installation direction contrary (see Fig. 3) of two side blades, upward, down, such workpiece rotates and ensures that both sides blade all can cut side blade side blade.Adjust the size (see Fig. 2) in the large footpath of the blade conical surface by the adjustment screw 3 of end large on cutter holder 1, ensure that it is consistent with hole size with micrometer or vernier caliper measurement, and slight compression trip bolt 2 herein.The adjustment screw 3 adjusting cutter holder small end again carrys out the tapering number of degrees of adjustable blade, ensures that it is consistent with the workpiece drawing endoporus transition conical surface number of degrees, adopts universal protractor to guarantee to bore degree of a face.Fastening whole housing screw 2, guarantees that blade is firm, completes the installation of split cutter.
Insert in the tool bore of the tapering boring head 5 matched by installing the cutter holder after blade 1, boring head 5 adopt brace bar 6 locate (see Fig. 4) in macropore, drive forming-tool into macropore conical surface starting point from macropore port, complete large aperture transition cone face process by long feed.
