Abstract
An indexable hard alloy gear hobbing cutter relates to cutters and solves the problem that an existing common high-speed steel and cobaltic high-speed steel hobbing cutter can not meet the processing requirements of high speed gear hobbing of a high-speed hobbing machine. The utility model adopts the technical scheme that bolt holes, screw holes, key slots and pin holes are formed on each of helix angle monolithic bodies, a left end and a right end respectively; two adjacent helix angle monolithic bodies and the left and the right ends are fixed through bolts and arranged into an integral hobbing cutter; the plurality of helix angle monolithic bodies are positioned through keys or pins; indexing hard alloy cutter blade slots are formed on the helix angle monolithic bodies; and indexing hard alloy cutter blades are tangentially fixed in the indexing hard alloy cutter blade slots on the helix angle monolithic bodies. The indexable hard alloy gear hobbing cutter has the advantages that teeth of the gear hobbing cutter is indexable and replaceable; a cutter blade is fixed conveniently and stabilized reliably; a cutter body has high strength and good rigidity; and the gear hobbing cutter has the capability of high-speed cutting, so that the cutting efficiency can be increased by over 3 times.
Description
Technical field
The utility model relates to gear cutting tool, is specifically related to indexable carbide hob.
Background technology
At present, common hobboing cutter is to make by high-speed tool steel is whole, and cutting edge is a high-speed tool steel, and the high-speed tool steel of at present domestic the most normal use has two kinds, and a kind of machine tool high-speed tool steel is as W18Cr4v, w9, M2.Another kind of be the high speed gear hobber cobalt-containing high speed steel, as M35, M42 and contain the cobalt powder metallurgical high-speed tool steel.Be subjected to material itself restriction, existing common high-speed steel and the hobboing cutter that contains the high-speed steel of cobalt all can not carry out the processing of high speed gear hobber high speed gear hobbing.The high-speed steel hobboing cutter can not carry out high-speed cutting, so efficient is low, the welding carbide hob does not satisfy the production demand because of the grinding difficulty.
The utility model content
The utility model can not carry out high-speed cutting in order to solve existing common high-speed steel with the high-speed steel hobboing cutter that contains cobalt, so, efficient is low, the welding carbide hob is because of the grinding difficulty, do not satisfy the problem of production demand, a kind of indexable carbide hob is provided, and the concrete technical scheme that addresses the above problem is as follows:
Indexable carbide hob of the present utility model, by the transposition carbide chip, screw, the lead angle monolithic body, bolt, left end head and right-hand member head are formed, the lead angle monolithic body is a plurality of, the left end head, each lead angle monolithic body and right-hand member head are provided with bolt hole, screw hole and keyway and pin-and-hole, the left end head is enumerated into a hobboing cutter integral body with a plurality of lead angle monolithic body and right-hand member head by bolting, a plurality of lead angle monolithic body are with key or finger setting, be provided with transposition carbide chip cutter groove on the lead angle monolithic body, the transposition carbide chip tangentially is fixed on the cutter groove of lead angle monolithic body by screw.
The design feature of indexable carbide hob of the present utility model: one, the hobboing cutter cutter tooth has indexable property and commutativity; Two, the blade convenient fixing is solid and reliable; Three, cutter hub intensity height, good rigidly; Four, have the high-speed cutting ability, can improve stock-removing efficiency more than 3 times.The indexable gear hob of the utility model is applicable to the high-speed cutting of the above large module gear of M6.Indexable four times of each cutter tooth need not to unload the blade mill.The utility model can be used as various gear hobs, stays mill hobboing cutter and preshaving hob etc. as involute.

The specific embodiment
The specific embodiment one: describe present embodiment in conjunction with Fig. 1, Fig. 2, Fig. 3.Present embodiment is by transposition carbide chip 1, screw 2, lead angle monolithic body 3, bolt 4, left end head 5 and right-hand member head 6 are formed, lead angle monolithic body 3 is a plurality of, left end head 5, each lead angle monolithic body 3 and right-hand member head 6 are provided with bolt hole 7, screw hole 8 and keyway 9 and pin-and-hole 10, left end head 5 is fixedlyed connected by bolt 4 with the first lead angle monolithic body 3-1, the first lead angle monolithic body 3-1 is fixedlyed connected by bolt 4 with the second lead angle monolithic body 3-2, the second lead angle monolithic body 3-2 is fixedlyed connected by bolt 4 with triple helical lift angle monolithic body 3-3, triple helical lift angle monolithic body 3-3 is fixedlyed connected by bolt 4 with the 4th lead angle monolithic body 3-4, the 4th lead angle monolithic body 3-4 is fixedlyed connected by bolt 4 with the 5th lead angle monolithic body 3-5, the 5th lead angle monolithic body 3-5 is fixedlyed connected by bolt 4 with the 6th lead angle monolithic body 3-6, the 6th lead angle monolithic body 3-6 is fixedlyed connected by bolt 4 with right-hand member head 6 and is constituted a hobboing cutter integral body, a plurality of lead angle monolithic body 3 usefulness key or finger settings, be provided with the cutter groove of transposition carbide chip 1 on lead angle monolithic body 3, each transposition carbide chip 1 tangentially is fixed on the transposition carbide chip cutter groove of lead angle monolithic body 3 by screw 2.
The specific embodiment two: describe present embodiment in conjunction with Fig. 1.Present embodiment lead angle monolithic body 3 is 6, respectively one on left end head 5 and right-hand member head 6.
The specific embodiment three: describe present embodiment in conjunction with Fig. 1.Each lead angle monolithic body 3 of present embodiment is provided with a plurality of transposition carbide chips 1.
Operation principle:
The cutter tooth that indexable carbide chip 1 makes hobboing cutter prolongs service life of hobboing cutter by transposition, and cutter hub can use for a long time.
Finish one by hobboing cutter pitch thickness and have hobboing cutter spiral cylindrical.Spiral angle is undertaken by the hobboing cutter designing requirement, and unnecessary spiral part is removed, and the part of removing is filled with another part, is processed into the insert groove of required installation transposition carbide chip on the helicoid.Interconnect with bolt 4 fastening.According to the length of hobboing cutter, determine required blade number, every once is connected to form complete hobboing cutter body.
