Description

A kind of hole machined compound tool
Technical field
The utility model belongs to process tool technical field, is related to a kind of hole machined compound tool;Especially suitable for big Aperture through-hole aluminum component processing.
Background technology
Small hole machined usually is completed to process by drill bit, but with the increase in aperture, and the bar base material of processing drill is straight Diameter is also increasing;In high volume, the growth of the carbide drill base material cost of high efficiency processing causes the cost of charp tool with the order of magnitude Increase.
Large diameter hole is processed in a manner that carbide chip is installed on alloy cutter hub, is commonly called as U brills.It is single that U, which bores feature, The part cost of charp tool is low, high in machining efficiency;Shortcoming is that machining accuracy is not high, if Product Precision requirement is high, needs other finishing, half Finishing tool.Large aperture mechanical processing is generally divided into drilling, semifinishing hole, Finish Machining Bore, four step of orifice chamfer, with four Cutter machines;Cutter is more, and corresponding cutter purchase cost is high;Low production efficiency;Cutter brings tool changing when auxiliary more Between increase, be unfavorable for automobile industry high efficiency produce in enormous quantities.
Invention content
The utility model discloses a kind of hole machined compound tool, to solve the processing of prior art large pore through-hole part Wait the problems such as cost of charp tools are high, and cutter is more, low production efficiency.
The utility model includes the first ladder knife, the second ladder knife, third ladder knife, cutter hub;First ladder knife, second-order Terraced knife, third ladder knife are arranged along cutter hub axially spaced-apart;First ladder knife includes U and bores edge blade, U brill center inserts;U bores side Edge blade, U bore the front end that center insert is securedly mounted to cutter hub;Structure is bored using the U of existing maturation, enhances the effect of drilling Rate;Second ladder knife includes semifinishing blade, finishing blade;Semifinishing blade, finishing blade are securedly mounted to knife The middle part of body;Realize half right boring, boring combination;The participation of the participation processing point of a knife and fine boring cutter of half fine boring cutter processes point of a knife along knife Body has axial distance H, and H is equal to 3 times of amount of feeding f;It ensure that in process, acted on simultaneously there are two cutting force Cutter hub is avoided because of half right boring of the second ladder and boring combination, and because of allowance asymmetry, and then chip power changes greatly, processing Middle generation cutter chatter, aperture processing dimension are unstable;Third ladder knife includes chamfering blade;Third ladder knife is securedly mounted to knife The rear portion of body;Countersink form completes chamfer machining.
The first ladder of the utility model knife, the second ladder knife, third ladder knife along cutter hub axially spaced-apart arrange, spacing distance Workpiece, the second ladder knife incision workpiece are cut off for the first ladder knife;Second ladder knife cuts off workpiece, third ladder knife incision work Part;After the first ladder knife drills through workpiece, the second ladder knife semifinishing blade, finishing blade start to process;Workpiece passes through After semifinishing, finishing, hole is finished size;After second ladder knife machines, third ladder knife chamfering blade starts to add Work completes workpiece orifice chamfer;Cutting force acute variation caused by avoiding not at the same level while processing, directly avoids processing and shakes It quivers, ensures processing stability.
The utility model third ladder knife chamfering blade working position is blade side plane, and during semifinishing, blade is Consume point of a knife;Blade side plane is not engaged in cutting;It is cost-saved, after semifinishing blade to service life, the blade It can be additionally used in the processing of third stepped chamfers;Chamfering blade processes point of a knife consumption for the second ladder knife semifinishing blade and scraps knife Piece.
The utility model has the positive effect that:Conventional four steps processing is incorporated to time processing, is in turn avoided in processing The chatter caused by cutting edge is excessive;Right boring blade uses adjustable holder structure, and modularized design substantially reduces nonstandard knife The manufacturing expense of tool;Production efficiency is high.
Description of the drawings
Fig. 1 is that the first ladder of the utility model compound tool and the second ladder take over operating diagram;
Fig. 2 is that the second ladder of the utility model compound tool and third ladder take over operating diagram;
In figure:1 U bore edge blade, 2 U bore center insert, 3 semifinishing blades, 4 finishing blades, 5 chamfering blades, 6 cutter hubs, J workpiece, 3a participate in processing point of a knife, 4a participates in processing point of a knife, 5a working positions.
Specific embodiment
One embodiment of the utility model is described in detail below in conjunction with attached drawing.
The utility model embodiment is as shown in Figure 1, including the first ladder knife, the second ladder knife, third ladder knife, cutter hub 6; First ladder knife, the second ladder knife, third ladder knife are arranged along 6 axially spaced-apart of cutter hub;First ladder knife includes U and bores edge blade 1st, U bores center insert 2;U bores edge blade 1, U bores the front end that center insert 2 is securedly mounted to cutter hub 6;Using existing maturation U bore structure, enhance the efficiency of drilling;Second ladder knife includes semifinishing blade 3, finishing blade 4;Semifinishing blade 3rd, finishing blade 4 is securedly mounted to the middle part of cutter hub 6;Realize half right boring, boring combination;The participation processing knife of half fine boring cutter 3 Point of a knife 4a is processed in the participation of sharp 3a and 4 knife of right boring has an axial distance H along cutter hub 6, the amount of feeding f of and H=3;It ensure that and processing In the process, cutter hub is acted on simultaneously there are two cutting force, avoid because of half right boring of the second ladder and boring combination, because of allowance not Symmetrically, and then chip power changes greatly, and cutter chatter occurs in processing, and aperture processing dimension is unstable;Third ladder knife includes falling Angle blade 5;Third ladder knife is securedly mounted to the rear portion of cutter hub 6;Countersink form completes chamfer machining.
