Description
Technical field
The present invention relates to a kind of hobboing cutter, relate in particular to a kind of split type hobboing cutter.
Background technology
Hobboing cutter is a kind of conventional machining tool, is also a kind of continuous cutting cutter of multiple-cutting-edge.The hobboing cutter of traditional design, comprises cutter shaft and is circumferentially distributed in a plurality of cutters tooth on cutter shaft at present, between adjacent cutter tooth, is formed with chip pocket; Although existing gear hob production efficiency is higher, due to its cutter tooth negligible amounts, limited the further raising of its work effect; The how integrated formation of current cutter tooth and cutter shaft importantly, if in use one of them cutter tooth damages, its whole hobboing cutter just can not be used, this just causes the life-span of its use to reduce, the increase of cost, as the disclosed a kind of hobboing cutter of publication number: CN 103639534 A, and the disclosed a kind of gear hob of publication number: CN 102114557 A, are all the designs that adopt said structure.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to reality needs, a kind of long service life, detachable, the removable split type hobboing cutter of cutter hub are provided.
In order to realize object of the present invention, the technical solution adopted in the present invention is:
Design a kind of split type hobboing cutter, it comprises at least one cutter hub, for fixedly mounting the body of described cutter hub and for the fixed block of fixing described cutter hub, on described body, with circumferencial direction, offer the cutter hub holddown groove of at least one its upper end open, the fixed part correspondence of described cutter hub is arranged in this cutter hub holddown groove, and its cutter head portion protrudes from described body outside;
Both sides, bottom at described fixed block are respectively provided with a convex body, described fixed block correspondence is arranged on the body of cutter hub top, the convex body of one end, its fixed block bottom contacts with described cutter hub, and the convex body of the other end contacts with described body, described fixed block and being fixed on described body via bolt.
The length that the convex body contacting with cutter hub protrudes is greater than the length that contacts convex body with body.
On described fixed block, offer fixing hole, and on described body, offer the bolt mouth corresponding with described fixing hole, fixing hole being fixed in described bolt mouth described in described bolt-through, with by described fixed block fixed press.
Its cross section of the fixed part of described cutter hub is V-shaped, and its cutter head cross section is " ︹ " shape.
The cross section of described body is rounded, and offers the connecting hole for being connected with turning cylinder at the center of this body.
Described cutter hub holddown groove equidistantly evenly arranges.
Beneficial effect of the present invention is:
1. the present invention separates design by cutter hub and body, and by adopting fixed block that both are fixed, even if in use some cutter hubs damage, also can not affect the use of whole cutter hub, more causes the replacing of whole hobboing cutter, only needs to change wherein some cutter hubs; Ben is that the present invention is by the convex body of two protrusions of fixed block bottom design, and it is inconsistent that both protrude length, wait in use, by the fastening effect of bolt, the convex body of the protrusion length that it contacts with cutter hub can fully push cutter hub, and the convex body major part via the extruding force of bolt by fixed block below is pressed on cutter hub, can carry out extruding fully to cutter hub fixing, and cutter hub is positioned at cutter hub holddown groove, can prevent again the movement of its left and right directions, reach fixation better.
2. the present invention is secured by bolts in fixed block on body, and convenient disassembly can be adjusted the extruding force to fixed block by this bolt simultaneously, and then the extruding force of Adjustiny device body.
3. this hobboing cutter designs a plurality of cutter hub holddown grooves, in use can have more the quantity that needs to increase or reduce cutter hub, to adapt to different requirements of producing, and a kind of cutter hub provided by the present invention, in use can be not limited to this kind of cutter hub, can change at any time as required the shape of cutter hub, or change other cutter hubs and use.
4. this hobboing cutter connects with middle corresponding rotating shaft by the connecting hole on it, easy to operate, and is easy to install.
