Description
Technical field
This utility model relates to vehicle differential gear shell processing technique field, particularly relates to a kind of novel nonstandard differential shell milling cutter.
Background technology
The effect of differential mechanism is to make both sides vehicle wheel rotational speed different.When automobile turning, such as, turning left, flexual center is in left side, and within the identical time, right side wheels is longer than the track that left side wheel is passed by, thus right side wheels turn will be more faster.Reaching this effect, must be regulated by differential mechanism, differential mechanism is made up of machine components such as differential carrier, planetary gear, planetary gear axle and axle shaft gears.The power of electromotor, after variator driven shaft enters differential mechanism, directly drives differential carrier, then is delivered to planetary gear, moves left and right half gear, and then drives wheel, and the rotating speed sum of left and right semiaxis is equal to the twice of differential carrier rotating speed.When automobile straight-line travelling, planetary gear, left and right half gear is identical with driving wheel three's rotating speed.When cornering, owing to automobile stressing conditions changes, feedback is on the semiaxis of left and right, and then destroys the original balance of differential mechanism, this is that rotating speed is redistributed, and causes inboard wheel rotating speed to reduce, and outboard wheels rotating speed increases, again reaching poised state, meanwhile, automobile completes turning action.Differential carrier, as one of big shell of vehicle bridge three, is automobile industry typical part, and its processing focuses on driven gear installation site and the positional precision between the diameter of axle installed by bearing, and difficult point is the processing of inner chamber.At present, the processing of differential carrier is mainly by turnery processing, adds and man-hour this lathe tool stretches into differential mechanism embedded SMA actuators sphere, adds and have a lot of limitation man-hour, and the course of processing is complicated, and machining accuracy is low, needs often to change the position of cutter hub.
Summary of the invention
In order to solve problem above, this utility model provides a kind of novel nonstandard differential shell milling cutter, and its life-span is long, it is not necessary to sharpening; easy and simple to handle, unproductive time such as shutdown tool changing etc. can be shortened, indexing is convenient, fast, and can Reusability; service life is long, can reduce quantity in stock, simplifies tool management.
The technical solution of the utility model is: provide a kind of novel nonstandard differential shell milling cutter, it is made up of cutter holder, left hand blade, voussoir, voussoir screw, rose reamer block, jackscrew, tapered end jackscrew, scalpel body and right hand blade, cutter holder is fixed in scalpel body by screw lock, voussoir is fixed in scalpel body by voussoir screw, left hand blade, right hand blade are separately mounted between voussoir and cutter holder be locked by voussoir, left hand blade and right hand blade turn clockwise with scalpel body, and rose reamer block is fixed by jackscrew and tapered end jackscrew and regulated.
Preferably, rose reamer block chamfer angle is 45 °.
Preferably, left hand blade, right hand blade are circular arc blade.
Preferably, scalpel body is provided with axis hole.
Compared with prior art, the beneficial effects of the utility model are: geometric parameter and cutting ability are stable, and positioning precision and repeatable accuracy are higher, it is ensured that position of tool tip changes in workpiece accuracy allowed band, it is ensured that the concordance of machining accuracy.Left hand blade, the equal reliable clamping of right hand blade, be difficult to loosen under cutting force shock and vibration and heat in metal cutting effect.Cutter life is long, it is not necessary to sharpening, easy and simple to handle, can shorten unproductive time such as shutdown tool changing etc., and indexing is convenient, fast, and can Reusability, service life is long, can reduce quantity in stock, simplifies tool management.
