Abstract

A composite material tool bit of a replaceable milling tool comprises a tool bit component which comprises a tool body and a connecting seat, wherein the tool body is molded with a tool edge and is provided with a joint end; the connecting seat is welded and fixed on the joint end of the tool body; and a screw is protrudingly arranged on the connecting seat and can be combined with a screw hole of the existing tool handle. In the utility model, the tool body and the connecting seat are manufactured to two components and then fixedly connected with each other, therefore the material with low cost can be chosen for manufacturing the connecting seat, and the purpose of saving the manufacturing and using costs of the tool bit is achieved.

Description

The composite cutter head of alternate form milling cutter

Technical field

The utility model is about a kind of cutter head of milling cutter, refers in particular to this cutter head and is by being constituted in order to the cutter hub of cutting workpiece and the joint seat that is fixedly arranged on cutter hub one side.

Background technology

Milling cutter is meant a kind of cutting cutter, mainly has a handle of a knife that is the round bar body, form blade in this handle of a knife one end, be to be installed in a machining machine and tool and to be driven and rotate during use with handle of a knife, and make milling cutter carry out the machining of workpiece with the blade position to the workpiece feeding of desire processing, for making this blade be enough to reaching the purpose of cutting workpiece, its general material such as carbonization wolfram steel with high rigidity of using is made.

In the existing milling cutter, being that handle of a knife and blade are integrally formed makes, and when treating that this blade can't re-use because of abrasion, is with whole milling cutter to be changed, yet in fact milling cutter only has the blade position to wear away in use, therefore with the whole rising that will cause cutter changing use cost;

For solving above-mentioned shortcoming, develop to have at present milling cutter is designed to have a handle of a knife and a cutter head that is made as a member separately, on cutter head and handle of a knife and be respectively equipped with combined structure, for example on handle of a knife, be arranged with a screw, establish a screw rod and on cutter head, dash forward, screw rod is combined with screw and cutter head and handle of a knife can be combined into a milling cutter, in the time of can't using when the blade abrasion, only need change this cutter head and need not abandon handle of a knife, therefore can reduce because of changing the cost of handle of a knife.

In the aforementioned milling cutter, its cutter head is whole to use identical material such as high-hardness tungsten carbide is one-body molded makes, yet, because only using for cutter head and handle of a knife, this combined structure links, when replacing cutter head, will be abandoned in the lump, this combined structure is the material of unnecessary use blade special use in fact, and expense is very high in that processing high-hardness tungsten carbide screw rod processing procedure is difficult, and therefore this existing milling cutter tip still has the higher shortcoming of use cost.

The utility model content

Because the shortcoming of above-mentioned existing milling cutter, the utility model is designed to solid memder respectively by blade position and the combined structure with cutter head, but make the cheaper material of this combined structure cost of use, solve the use cost of existing milling cutter tip according to this and be difficult for processing problems.

For reaching above-mentioned creation purpose, the employed technological means of the utility model is to provide a kind of composite cutter head of alternate form milling cutter, and it includes:

One cutter head assembly includes a cutter hub and a joint seat, wherein form blade on this cutter hub and have an abutting end, and an end of this joint seat is fixedly welded on the cutter hub abutting end, and the other end of joint seat is equipped with a screw rod.

Wherein, this screw rod can combine with the screw on being located at an existing handle of a knife.

From the above, the cutter hub of described cutter head assembly and joint seat are to be made as two members respectively, when actual production, this cutter hub can select for use the material that is suitable as blade such as high-hardness tungsten carbide or other high hardness alloy to make, and this joint seat can select for use general carbon steel, stainless steel to make, can further reduce the Master Cost of cutter head assembly by this technological means, make cutter head on using, have better economic benefit.

The specific embodiment

Referring to Figure 1 and Figure 2, the composite cutter head of alternate form milling cutter of the present utility model, it can be incorporated on the existing handle of a knife 10 and use, this handle of a knife 10 is the round bar body, be concaved with a tank 11 on the axial end, these tank 11 bottom surfaces further are concaved with screw 12 certainly, and the utility model includes a cutter head assembly 20, this cutter head assembly 20 includes a cutter hub 21 and a joint seat 22, wherein:

This cutter hub 21 is the round bar body in present embodiment, form blade 211 and helicla flute 212 on the cutter hub 21, has an abutting end 213 in an axial end;

This joint seat 22 is for being the round bar body that has same outer diameter as with cutter hub 21, its axial end is fixed on cutter hub 21 abutting ends 213 in the mode of welding, the joint seat 22 axial other ends are equipped with a bead 221, the external form of this bead 221 is matched with the tank 11 of handle of a knife 10, be provided with a screw rod 222 from the further projection of these bead 221 free ends, this screw rod 222 can mutually combine with the screw 12 of handle of a knife 10;

Shown in Fig. 2,3, when the utility model desire is used, be to make the screw rod 222 of cutter head assembly 20 be incorporated in the screw 12 of handle of a knife 10, and the bead 221 of cutter head assembly 20 enters in the tank 11 of handle of a knife 10, by this cutter head assembly 20 is connected to an end of handle of a knife 10, otherwise when milling cutter during the wearing and tearing of the blade 211 of cutter head assembly 20, is to make screw rod 222 withdraw from the screw 12 of handle of a knife 10 to carry out the replacing of cutter head assembly 20 through use.

In the utility model, described joint seat 22 is in order to the binding effect between cutter hub 21 and the handle of a knife 10 to be provided, therefore it need not have high rigidity as cutter hub 21, and because in the utility model, the cutter hub 21 and the joint seat 22 of described cutter head assembly 20 are to be made as two members respectively, be bonded with each other with welding manner more subsequently, joint seat 22 therefore of the present utility model can select for use suitable material to make according to desired engineering properties respectively with cutter hub 21, than the mode of the replaceable milling cutter use of existing cutter head as the one-body molded making cutter head of material of cost costlinesses such as high-hardness tungsten carbide, the utility model can reach the effect of saving milling cutter making and use cost.
