Abstract
The utility model relates to a cutter, including cutting member and extension piece, a cutting member and an extension interference fit, the cutting member include that cutting head and axial projection are for the circular shape connecting piece, cutting head and connecting piece integrated into one piece, the extension piece include an axial projection for the circular shape body, the body axial becomes to link up the design and divide into through -hole and through -hole down, lower through -hole is convenient for and blade holder interference fit, goes up the connecting piece interference fit of through -hole and cutting member. Including cutting member and extension, a cutting member and an extension interference fit, two effective connections between this have been guaranteed, after cutting a period simultaneously, when cutter wearing and tearing appeared and needs to be changed, the cutting member that only needs to be changed need not to change extension, and the cutter that designs like this compares prior art's cutter, the utility model discloses cutter's cutting head part size 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 cutter.
Background technology
Along with industrial expansion, especially metal manufactures field, all refers to cut the equipment of metal, including
A series of machining equipments such as milling machine, machining center, drilling machine.Wherein be directed to cutter use and
Design.By having tool rest and cutter two parts assembly on the processing assembly of the said equipment, Cutting tool installation manner is existed
On tool rest, complete processing action miscellaneous.Cutter includes cutter head and handle of a knife two parts assembly, with work
The tool bit part of part contact, when abrasion occurs in tool bit part, whole cutter is accomplished by changing.To user
For, loss is relatively big, and replacement cost is high.So designing a one that can reduce and change the cost of charp tool
New-type cutter is the most required.
Utility model content
Technical problem to be solved in the utility model is: provides one to be easy to user and reduces replacement cost
Cutter.
Technical solution adopted in the utility model is: a kind of cutter, including cutting member and extension device, institute
The cutting member stated and extension device interference fit；Described cutting member includes that cutting head and axis projection are for circle
Connector, described cutting head and connector are one-body molded；Described extension device includes an axis projection
For circular body, body axially becomes pass-through design and is divided into through hole and lower through-hole, lower through-hole be easy to
The connector interference fit of tool rest interference fit, upper through hole and cutting member.
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 extension device is more than the external diameter of upper through hole place body.
Described cutting head includes blade bearing and blade, and described blade is through being bolted on blade bearing.
The beneficial effects of the utility model are: a kind of cutter, including cutting member and extension device, cutting member with
Extension device interference fit, it is ensured that the two effective connections between this；After cutting a period of time simultaneously, when
Cutter occurs when abrasion needs to change, it is only necessary to change cutting member, it is not necessary to change extension device, so design
Cutter, cutter compared to existing technology, the cutting head portion size of this utility model cutter will compare
Short, low cost of manufacture, user replacement cost is the lowest.

Detailed description of the invention
With reference to cutter a kind of shown in Fig. 1-Fig. 3, including cutting member 1 and extension device 2, described cutting member 1
With extension device 2 interference fit；Described cutting member 1 includes that cutting head 1.1 and axis projection are circular
Connector 1.2, described cutting head 1.1 and connector 1.2 are one-body molded；Described extension device 2 includes
One axis projection is circular body, and body axially becomes pass-through design and is divided into through hole 2.1 and lower through-hole
2.2, lower through-hole 2.2 is easy to and tool rest interference fit, upper through hole 2.1 and the connector 1.2 of cutting member 1
Interference fit.Cutting member 1 (hard alloy making) and extension device 2 (rustless steel making), utilize hard
Interference fit made by alloy and the difference of stainless steel material thermal coefficient of expansion and principle of expanding with heat and contracting with cold.
The external diameter of described cutting head 1.1 is more than the external diameter of connector 1.2.
Described cutting head includes blade bearing and blade, and described blade is through being bolted on blade bearing.
This body diameter of lower through-hole 2.2 place of described extension device 2 is more than upper through hole 2.1 place body
External diameter.
This utility model includes cutting member and extension device, cutting member and extension device interference fit, it is ensured that two
Effective connection between this；After cutting a period of time simultaneously, when cutter occurs that abrasion needs to change,
Have only to change cutting member, it is not necessary to change extension device, the so cutter of design, cutter compared to existing technology
Tool, the cutting head portion size of this utility model cutter will be comparatively short, low cost of manufacture, and user is more
Change this into the lowest.
As a kind of improvement of the present utility model, on described extension device 2, the basis at through hole 2.1 place is external
The inclined design in surface.The described angle corresponding to inclination is 3 °.The lower through-hole of described extension device 2
2.2 place body part outer walls with the chamfering of the junction of upper through hole 2.1 place body part outer wall are
45°。
