Abstract
The utility model discloses a spiral end mill with a replaceable milling cutter. The existing spiral end mill adopts an integral structure, when an end tooth blade slot is worn and damaged and the precision can not meet the using requirement, the whole end mill is scrapped, so that the cost of the tool is multiplied and the cutting and processing cost is greatly increased. In the traditional mode of transmitting torque by a cylindrical pin, the cross section is small and the bearable cutting load is not large, so that the cutting performances of the end mill are influenced to a certain extent. The spiral end mill with the replaceable milling cutter comprises a mill body (1), wherein the mill body (1) and a cutter (2) are connected with by a key and centered by a cylindrical surface (3). The utility model is used for the spiral end mill with the replaceable milling cutter.
Description
Technical field:
The utility model relates to a kind of helical end mills, is specifically related to a kind of interchangeable helical end mills of being with.
Background technology:
Existing helical end mills adopts monolithic construction, when the wearing and tearing of end tooth insert groove, damage, when precision can't satisfy instructions for use, wholely all will scrap milling cutter, thereby tool expense is doubled and redoubled, and has greatly increased the machining cost.Traditional straight pin transmits the mode of moment of torsion, and cross-sectional area is little, and the shear load that can bear is little, has influenced the cutting ability of milling cutter to a certain extent.
Summary of the invention:
The purpose of this utility model has provided a kind of part that the slotting cutter front end is perishable and has made interchangeable structure, can change at any time after the damage, and do not influence the milling cutter main part use be with interchangeable helical end mills structure.
Above-mentioned purpose realizes by following technical scheme:
Be with interchangeable helical end mills, its composition comprises: described cutter hub connects cutter head, is connected, feels relieved by the face of cylinder with key between described cutter head and the cutter hub.
Beneficial effect:
1. the utility model adopts the perishable part of slotting cutter front end to make the face of cylinder interchangeable structure movingly, can change at any time after the damage, and not influence the use of milling cutter main part, thereby improve the economy that instrument uses.
2. the utility model adopts between interchangeable head and the cutter hub and adopts protruding key to transmit the connected mode of moment of torsion.Have bigger cross-sectional area, can bear higher shear load.
3. the utility model has greatly reduced the cost of use of instrument, saves processing cost.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is accompanying drawing 1 left views.
The specific embodiment:
Embodiment 1:
Be with interchangeable helical end mills, its composition comprises: cutter hub 1, and described cutter hub 1 connects cutter head 2, and with face of cylinder centering 3, key transmits the connected mode of moment of torsion between described cutter head 2 and the cutter hub 1.
Embodiment 2:
Embodiment 1 is described to be with interchangeable helical end mills, and this helical end mills is divided into interchangeable head and two parts of cutter hub to cutter with whole, and replaceable head divides fragile, can change after the damage, and not influence the use of cutter hub.
Process principle:
The perishable part of slotting cutter front end is made interchangeable structure, can change at any time after the damage, and not influence the use of milling cutter main part, thereby improve the economy that instrument uses.
Adopt cylinder centering between interchangeable head and the cutter hub, protruding key transmits the connected mode of moment of torsion.Have bigger cross-sectional area, can bear higher shear load.
Claims (1)
1. be with interchangeable helical end mills for one kind, its composition comprises: cutter hub is characterized in that: described cutter hub connects cutter head, is connected, feels relieved by the face of cylinder with key between described cutter head and the cutter hub.
