Description
technical field:
The utility model is relevant with the process tool of travelling gear in the equipment such as automobile, lathe.
background technology:
Middle fine module gear is widely used in the industry such as automobile, lathe, and the Milling Process mode of gear is also widely used.The cutter of current gear Milling Process is mainly monoblock type or welded type.Integral gear material of cutting-tool is generally high-speed steel, and welded-type gear milling cutter cutting tip material is generally carbide alloy, and body portion is generally carbon steel.No matter monoblock type or welded type, it is all relatively serious to the waste of material, when cutter can not meet Gear Processing require time, cutter just entirety is scrapped, and uses even if part cutter can repeat reconditioning, but its grinding efficiency is lower, reconditioning costly.In addition, all land mouth molding modes of original monoblock type or welded-type gear milling cutter are profile copy grinding processing, its precision and surface quality are all lower, and the accuracy of gear of current Milling Process generally can only reach 8 grades, so gear milling cutter is generally only used as the roughing of gear.
utility model content:
It is simple that the purpose of this utility model is to provide a kind of structure, and need not change tool setting, long service life, cost is low, and working (machining) efficiency is high, and what machining accuracy was high is applicable to low module machine clip variable-position gear milling cutter in the plate-like of middle fine module gear Milling Process.
The utility model is achieved in that
Circumferential periphery several tool rest grooves uniform of cutter hub 1, the sagittal plane of tool rest groove is connected with tool rest 3, compress voussoir 5 and compress tool rest 3 in tool rest groove by inclined-plane, tool rest 3 there is isosceles trapezoid insert groove coordinate with equilateral triangle cutter blade 2, cutter blade 2 is fixed on the inclined-plane of the insert groove on tool rest 3 by wabbler screw 4, and fastening bolt 6 is locked and compressed voussoir 5 on cutter hub 1.
Uniform six the tool rest grooves of circumferential periphery of cutter hub 1, six cutter blades are uniformly distributed in the circle end face of cutter hub 1.
The inscribed circle of the equilateral triangle of cutter blade 2 is φ 9-φ 13mm, and each angle of equilateral triangle respectively has the cutting edge that identical, each cutting edge all opens anterior angle.
The utility model adopts advanced design concept, integrated use theory of metal cutting and Design of Mechanical Structure, milling cutting insert cutting edge part adopts form grinding mode, solves the problems such as middle fine module gear Milling Process precision is low, efficiency is low, fineness is poor, complicated operation.Through repeatedly field trial prove gear quality that the utility model processes comparatively integral cutter greatly promote, solve the problems such as machining accuracy is low, fineness is poor, its machining accuracy can be stablized and reaches 7 grades, in process, workman no longer carries out the work such as repetition tool changing, tool setting, and efficiency improves greatly.Cutter blade adopts machine clip variable-position carbide chip, and it is convenient to change, and service life and working (machining) efficiency higher; Different gear processing only need be changed tool rest and blade and use same cutter hub, cost-saving.
The utility model has the following advantages:
1. cutter adopts machine clip variable-position design, and cutter blade adopts the indexable structure of equilateral triangle, and every sheet blade has three eschangeable cutting swords, has saved a large amount of repetition tool changing tool setting time.Production efficiency improves more than 30%.
2. cutter blade adopts hard alloy coating material, and cutting-tool's used life improves nearly one times.
3. milling cutting insert cutting edge part adopts form grinding mode, and its accuracy of gear processed can improve a more than grade.
4. cutter adopts interchangeable tool rest as the loading body of blade, and different gear adds only need be changed corresponding tool rest and blade man-hour and without the need to changing cutter hub, decrease user's cutter hub inventory.
5. it is attractive in appearance that the design for aesthetic incorporated in the design of cutter makes product have more, and relative to welded type or integral cutter, improves the class of product.
