Abstract
The utility model provides a finger-type gear milling cutter which relates to an improvement on the structure of the finger-type gear milling cutter. The utility model provides the finger-type gear milling cutter capable of removing an inflexion. The finger-type gear milling cutter comprises a cutter body which consists of a cutter handle and a cutter head, wherein a cutting edge of the cutter head comprises an involute section, an arc section and a straight line section. The structural outline is as follows: an oblique line transition section is formed between the involute section and the arc section, and the included angle between the oblique line transition section and the axes of the cutter body is 3 to 8 degrees.
Description
Technical field:
The utility model relates to the improvement of finger-type gearmilling cutter structure.
Background technology:
Gear milling cutter is the dedicated tool of form of gear tooth processing, and its tooth Shape Design is identical with processing form of gear tooth, the tooth Shape Design decision tooth-formation of gear of gear milling cutter.
As shown in Figure 1, the cutting edge of present finger-type gearmilling cutter profile of tooth is made up of three parts: involute section AB, arc section BC, straightway CD.Finger-type gearmilling cutter because can not rounding off, have formed flex point at B point place, and flex point place stress is concentrated, and produces sharp angle effect; Because tangible flex point is arranged, make finger-type gearmilling cutter when heat-treatment quenching, form formation of crack herein, be prone to crackle and cracking; Because the existence of flex point makes gear surface not slick and sly fin curved surface occur, serious wear, meshing performance is poor, and transmission is not steady.R=6 is less for the finger-type gearmilling cutter root fillet, and the cutter head cutting hardness of finger-type gearmilling cutter is poor, very easily fracture, and the phenomenon of forging a knife is serious, causes Gear Processing expensive, poor efficiency.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of finger-type gearmilling cutter of eliminating flex point is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises the cutter hub of finger-type gearmilling cutter, cutter hub is to be made of handle of a knife, cutter head, the cutting edge of cutter head comprises involute section, arc section, straightway, between its structural feature involute section, the arc section is the oblique line changeover portion, and the oblique line changeover portion is 3 °～8 ° with the axis angle of cutter hub.
The beneficial effects of the utility model:
1, finger-type gearmilling cutter of the present utility model utilizes the oblique line changeover portion that involute section and root circle segmental arc formation rounding off are connected, and has avoided the formation of flex point; Simultaneously, improved cutter intensity and service life, reduced because cracking of cutter, the economic loss of forging a knife and causing owing to increased finger-type gearmilling cutter root fillet R=8.6; Only this item can reduce cutter and consume more than 30%;
2, finger-type gearmilling cutter of the present utility model, owing to eliminated flex point, the sharp angle effect that cutter stress is concentrated disappears; Solved that cutter ruptures and this difficult problem of forging a knife in Gear Processing, thereby saved Tool Design manufacturing expense about 20%;
3, finger-type gearmilling cutter of the present utility model has not only improved form of gear tooth precision, has reduced roughness; And the gear slide coefficient is diminished, the tooth root roughness reduces; Thereby increased gear root intensity, prevented gear tooth breakage, realized Gear Processing high-quality, high efficiency, low consumption, can enhance productivity more than 30%.
Description of drawings:
Fig. 1 is the structural representation of existing finger-type gearmilling cutter;
Fig. 2 is the structural representation of finger-type gearmilling cutter of the present utility model.
The specific embodiment:
The utility model comprises the cutter hub 1 of finger-type gearmilling cutter, cutter hub 1 is to be made of handle of a knife 2, cutter head 4, the cutting edge 5 of cutter head 4 comprises involute section AB, arc section CD, straightway DE, be oblique line changeover portion BC between involute section AB, the arc section CD, oblique line changeover portion BC is 3 °～8 ° with the axis 3 angle β of cutter hub 1.
Embodiment 1:
As shown in Figure 2, the cutting edge 5 of finger-type gearmilling cutter is involute section AB, oblique line changeover portion BC, arc section CD, straightway DE; Oblique line changeover portion BC is 3 ° 9 ' 6 with the axis 3 angle β of cutter hub 1 ".
Claims (2)
1, a kind of finger-type gearmilling cutter, the cutter hub (1) that comprises finger-type gearmilling cutter, cutter hub (1) is to be made of handle of a knife (2), cutter head (4), the cutting edge (5) of cutter head (4) comprises involute section (AB), arc section (CD), straightway (DE), it is characterized in that being oblique line changeover portion (BC) between involute section (AB), the arc section (CD), axis (3) angle (β) of the same cutter hub of oblique line changeover portion (BC) (1) is 3 °～8 °.
2, a kind of finger-type gearmilling cutter according to claim 1 is characterized in that axis (3) angle (β) of the same cutter hub of oblique line changeover portion (BC) (1) is 3 ° 9 ' 6 ".
