Abstract
The utility model relates to a metal cutting device, including cutting member, connecting piece and handle of a knife body, cutting member and connecting piece interference fit, two effective connections between this have been guaranteed to cutting member and connecting piece interference fit, after cutting a period simultaneously, when the cutter wearing and tearing appeared and needs to be changed, the cutting member that only needs to be changed need not to change the connecting piece, and prior art's cutter is compared to the cutter that designs like this, the utility model discloses the cutting head part size of cutter will be shorter, and low in manufacturing cost, user's replacement cost are also low. It equips technical field to belong to metal cutting.
Description
Technical field
This utility model belongs to Metal Cutting equipment technology field, especially relates to a kind of metal-cutting device.
Background technology
Along with industrial expansion, especially metal manufactures field, all refers to the equipment of cutting metal, a series of machining equipments such as including milling machine, machining center, drilling machine.Wherein it is directed to using and designing of cutter.By having handle of a knife body and cutter two parts assembly on the processing assembly of the said equipment, by Cutting tool installation manner on handle of a knife body, complete processing action miscellaneous.Because connecting rod differs 40-50 times with the material price of handle of a knife matrix, in order to material cost is greatly reduced.So handle of a knife is made up of connecting rod (special stainless steel is made) and handle of a knife matrix (ordinary carbon steel is made) two sections of material of clamping cutter head.These the most frequently used handle of a knifes, can significantly reduce the cost of charp tool to user.So it is required at present for designing a a kind of new-type cutter changing the cost of charp tool that can reduce.
Utility model content
Technical problem to be solved in the utility model is: providing a kind of cutter clamping convenient, in high precision, high chucking power, high speed windage is little, interferes little, the metal-cutting device of low cost.
Technical solution adopted in the utility model is: a kind of cutter, and including cutting member, connector and handle of a knife body, described cutting member and connector interference fit, described connector is connected with handle of a knife body；Described cutting member includes cutting head and axis projection is circular connector, and described cutting head and connector are one-body molded；Described connector includes the body that an axis projection is circle, and body axially becomes pass-through design and is divided into through hole and lower through-hole, and lower through-hole is connected with handle of a knife body；The connector interference fit of upper through hole and cutting member.
Described connector and handle of a knife body interference fit or weld.
The external diameter of described cutting head is more than the external diameter of connector.
This body diameter of lower through-hole place of described connector is more than the external diameter of upper through hole place body.
The inclined design of the body outer surface at through hole place on described connector.
The described corresponding angle that tilts is 3 °.
The beneficial effects of the utility model are: a kind of metal-cutting device, including cutting member and connector, cutting member and connector interference fit, it is ensured that the two effective connections between this；After cutting a period of time simultaneously, when cutter occurs that abrasion needs to change, it is only necessary to change cutting member, without changing connector, the so cutter of design, cutter compared to existing technology, comparing existing the most frequently used collet chuck handle of a knife, it does not have nut, collet chuck, unrelated with proficiency, can accurately installing in high precision, big 3 times of chucking power, high rotating speed windage is little, interfere little, very big metal-cutting device lower than hydraulic pressure handle of a knife cost.

Detailed description of the invention
With reference to metal-cutting device a kind of shown in Fig. 1-Fig. 4, including cutting member 1, connector 2 and handle of a knife body 3, described cutting member 1 and connector 2 interference fit, described connector 2 is connected with handle of a knife body 3；Described cutting member 1 includes cutting head 1.1 and axis projection is circular connector 1.2, and described cutting head 1.1 and connector 1.2 are one-body molded；Described connector 2 includes the body that an axis projection is circle, and body axially becomes pass-through design and is divided into through hole 2.1 and lower through-hole 2.2, and lower through-hole 2.2 is connected with handle of a knife body 3, connector 1.2 interference fit of upper through hole 2.1 and cutting member 1.
Described connector 2 and handle of a knife body 3 interference fit or weld.
Connector 2 lower end is connected with handle of a knife body 3, and the material cost used by connector 2 is high, if the material that handle of a knife body 3 is also adopted by connector 2 makes, the cost of so whole cutter is just expensive, make so adopting stagewise to connect, when the later stage changes cutter so that replacement cost is relatively low.
The external diameter of described cutting head 1.1 is more than the external diameter of connector 1.2.
This body diameter of lower through-hole 2.2 place of described connector 2 is more than the external diameter of upper through hole 2.1 place body.
The inclined design of body outer surface at through hole 2.1 place on described connector 2.
The described corresponding angle that tilts is 3 °.
The chamfering of the junction of the lower through-hole 2.2 place body part outer wall of described connector 2 and upper through hole 2.1 place body part outer wall is 45 °.
This utility model includes cutting member, connector, cutting member and connector interference fit, it is ensured that the two effective connections between this；After cutting a period of time simultaneously, when cutter occurs that abrasion needs to change, it is only necessary to change cutting member, without changing connector, the so cutter of design, cutter compared to existing technology, comparing existing the most frequently used collet chuck handle of a knife, it does not have nut, collet chuck, unrelated with proficiency, can accurately installing in high precision, big 3 times of chucking power, high rotating speed windage is little, interfere little, very big metal-cutting device lower than hydraulic pressure handle of a knife cost.The cutting head portion size of this utility model cutter will be comparatively short simultaneously, and low cost of manufacture, user replacement cost is also low.
