Abstract
The invention discloses a kind of drill bits using multitool access slot, including cutter shaft and cutter head, the cutter head is correspondingly arranged in cutter shaft one end, the cutter head includes the first cutter head and the second cutter head, the diameter of first cutter head is less than the diameter of the second cutter head, the diameter of second cutter head is less than the diameter of cutter shaft, it is correspondingly arranged on the first fluting on first cutter head, it is correspondingly arranged on the second fluting on second cutter head, first fluting is using the minimum diameter of drill bit as core thickness, second fluting is using the maximum gauge of drill bit as core thickness, the smooth connection in connecting pin of first fluting and the second fluting.The present invention is slotted using multitool, both can guarantee that the cutting of cutter apex was brisk, chip removal is smooth, and can guarantee the rigidity of cutter, intensity.
Description
Technical field
The present invention relates to mechanical processing cutter fields, more particularly to a kind of drill bit using multitool access slot.
Background technology
It is conventional during making cutter for step drop in nonstandard cutter up to 3 times and 3 times or more of drill bit
Fluting can make cutter root（At big outer diameter）Core so as to cause cutter poor rigidity, is easy to happen fracture, influences cutter thicker than small
Service life.As only slotted using the mode of grooving for promoting geometric angle, the entire groove profile of cutter can be made to change, chip space meeting
Greatly, tread can be small, and cutter rigidly can be insufficient, and tipping or breaking easily occurs.
Invention content
It is slotted using multitool the invention mainly solves the technical problem of providing a kind of, both can guarantee that the cutting of cutter apex was light
Soon, chip removal is smooth, and can guarantee the drill bit using multitool access slot of the rigidity of cutter, intensity.
In order to solve the above technical problems, one aspect of the present invention is：It provides a kind of using multitool access slot
Drill bit, including cutter shaft and cutter head, the cutter head are correspondingly arranged in cutter shaft one end, and the cutter head includes the first cutter head and the second knife
Head, the diameter of first cutter head are less than the diameter of the second cutter head, and the diameter of second cutter head is less than knife
The diameter of axis is correspondingly arranged on the first fluting on first cutter head, and being correspondingly arranged on second on second cutter head opens
Slot, it is that core is thick that first fluting, which is using the minimum diameter of drill bit, second fluting be it is thick by core of the maximum gauge of drill bit,
The smooth connection in connecting pin of first fluting and the second fluting.
In a preferred embodiment of the present invention, the first fluting there are two being correspondingly arranged on first cutter head.
In a preferred embodiment of the present invention, the first fluting helically structure setting.
In a preferred embodiment of the present invention, one end of first fluting is correspondingly arranged in the second fluting.
In a preferred embodiment of the present invention, it is described second fluting setting there are two equally twist structure with it is described
First fluting is arranged in a one-to-one correspondence.
In a preferred embodiment of the present invention, one end of second fluting is correspondingly arranged on cutter shaft.
The beneficial effects of the invention are as follows：The present invention is slotted using multitool, both can guarantee that the cutting of cutter apex was brisk, chip removal is suitable
Freely, and the rigidity of cutter, intensity be can guarantee.
Description of the drawings
Fig. 1 is the front view of drill bit one preferred embodiment of the present invention using multitool access slot；
Fig. 2 is the left view of Fig. 1.
Specific implementation mode
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
It please refers to Fig.1 and combines Fig. 2, the embodiment of the present invention includes：A kind of drill bit using multitool access slot, including 1 He of cutter shaft
Cutter head, the cutter head are correspondingly arranged in 1 one end of cutter shaft, and the cutter head includes the first cutter head 2 and the second cutter head 3, first knife
First 2 diameter is less than the diameter of the second cutter head 3, and the diameter of second cutter head 3 is big less than the diameter of cutter shaft 1
It is small, it is correspondingly arranged on the first fluting 4 on first cutter head 2, the second fluting 5 is correspondingly arranged on second cutter head 3, it is described
It is that core is thick that first fluting 4, which is using the minimum diameter of drill bit, second fluting 5 be it is thick by core of the maximum gauge of drill bit, it is described
The smooth connection in connecting pin of first fluting 4 and the second fluting 5 is correspondingly arranged on first cutter head 2 there are two the first fluting 4,
Helically structure setting, one end of first fluting 4 are correspondingly arranged in the second fluting 5 first fluting 4, and described second
There are two 5 settings of fluting, and equally twist structure is arranged in a one-to-one correspondence with first fluting 4, and the one of second fluting 5
End is correspondingly arranged on cutter shaft 1.
It when processing, is slotted using multitool, for example two knives is divided to slot, the first knife is slotted c, a on the basis of cutter minimum diameter
It is the core thickness after the first knife fluting；Second knife is slotted d on the basis of cutter maximum gauge, and b is that the core after the second knife fluting is thick；Together
When ensure the smooth connection of two bar grooves.
The present invention is a kind of drill bit using multitool access slot, and the present invention is slotted using multitool, both can guarantee that cutter apex was cut
Cut brisk, chip removal is smooth, and can guarantee the rigidity of cutter, intensity.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
