Description
Technical field
The utility model relates to cutter fields, and in particular to a kind of shift case specific complex drills and reams milling cutter.
Background technique
Currently, the traditional machining processes in process operation hole are as follows on shift case: bit bore is first used, then is reamed with reamer,
Then rose reamer chamfering, last milling tool end face are used.The process route of above-mentioned traditional machining processes is longer, needs four knives
Tool, four work steps, need multiple tool changing, and production efficiency is extremely low, are badly in need of solving above-mentioned technical problem thus.
Summary of the invention
Place in view of the deficiency of the prior art, the utility model are intended to provide a kind of shift case specific complex and drill and ream
Milling cutter is completed at the same time drilling, fraising, chamfering and the processing content of milling end face four by a cutter, reduces cutter investment, and
And it is greatly improved productive temp.
In order to achieve the above object, the utility model uses following technical scheme:
A kind of shift case specific complex drills and reams milling cutter, it is characterised in that: including be sequentially coaxially arranged bit head, reamer
Portion, rose reamer portion, milling cutter portion, extension, shank section, wherein the bit head, reamer portion, the integrated molding of rose reamer portion；Institute
State milling cutter portion, extension, shank section are integrally formed, the outrigger shaft and the milling that the rose reamer portion is arranged by its end
The hole cooperation of knife portion center setting, and the fastening of the sunk screw by being arranged radially, the bit head is straight groove structure, and described
Straight groove structure extends to the end in the milling cutter portion.
Further, the rose reamer portion is pyramidal structure left small and right large, and taper is 90 °.
Further, the bit head, reamer portion, rose reamer portion, milling cutter portion, extension are provided with alloy-layer.
The beneficial effects of the utility model include: to realize that one completes drilling, fraising, chamfering and milling end face four cutter
Process accelerates productive temp, improves production efficiency, and the utility model structure is simple, easy to manufacture, and vulnerable part can be more
It changes, reduces processing cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlarged view of A in Fig. 1.
Specific embodiment
Combined with specific embodiments below and attached drawing is further described the utility model.
A kind of shift case specific complex as depicted in figs. 1 and 2 drills and reams milling cutter, including be sequentially coaxially arranged bit head 1,
Reamer portion 11, rose reamer portion 2, milling cutter portion 3, extension 4, shank section 5, wherein bit head 1, reamer portion 11, rose reamer portion 2 one
It is body formed；Milling cutter portion 3, extension 4, shank section 5 are integrally formed, outrigger shaft that rose reamer portion (2) are arranged by its end and
The hole cooperation of milling cutter portion (3) the center setting, and two sunk screws by being arranged radially fasten.Its object is to work as
When 11 local damage of bit head 1 or reamer portion, the cost for reducing replacement cutter can be replaced, two parts is furthermore split into and makes
It makes, reduces manufacture difficulty, the manufacturing cost of milling cutter is lower so that shift case specific complex drills and reams.Bit head 1 is straight fluted drill,
And the straight groove structure of the straight fluted drill extends to the end in milling cutter portion 3.Using straight fluted drill, its rigidity is preferable, is suitble to add
Work hard material, and the circularity in the hole processed and straightness are higher.Rose reamer portion 2 is pyramidal structure left small and right large, cone
Degree is 90 °, and hole can be completed while completing fraising processing along the chamfer machining at position.
Drilling and reaming for the case specific complex that shift gears, the service life is longer for milling cutter, reduces the frequency of cutter changing, cutter
Bit head 1, reamer portion 11, rose reamer portion 2, milling cutter portion 3, extension 4 are provided with aluminium nitride chromium alloy layer.
Technical solution provided by the utility model embodiment is described in detail above, it is used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Assistant solves the principle of the utility model embodiment；At the same time, for those skilled in the art is implemented according to the utility model
Example, there will be changes in terms of specific embodiments and scope of application, in conclusion the content of the present specification should not be construed as
Limitations of the present invention.
