Second addendum cone is fixed on second support base, and first addendum cone and second addendum cone are oppositely arranged, and the pile crown can
It is installed on up or down on second support base, and the axis of pile crown is parallel with the axis of second addendum cone, in described
Heart detent mechanism is removably mounted on base, and between the first support base and the second support base.
Wherein, the center positioning mechanism includes：Described in lower chamber, upper cavity, dial gauge, spring, briquetting, pressure cap and general
The exhausting-gas hole that upper cavity is in communication with the outside, the spring and briquetting are located in upper cavity, the briquetting pressing spring, positioned at pressure cap
Lower section, the dial gauge are located in lower chamber, and through hole of the contact through upper cavity and lower chamber and spring Hard link.
Wherein, the base is equipped with two bar shaped mounting holes for being respectively used to fix the first support base and the second support base
Group, each bar shaped mounting hole group include two bar shaped mounting holes being parallel to each other.
The pile crown of the milling Woodruff key slots and keyways frock of the utility model can up and down adjustment, by the axial workpiece of eccentric structure (such as：
Crank), before holding out against, rotating part, while fine setting pile crown up and down is adjusted, pile crown is withstood eccentric orfice so that in eccentric orfice
The heart and key slot center are in same level, suitable for the axial workpiece of eccentric structure.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
Put, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is a kind of milling Woodruff key slots and keyways tool structure schematic diagram (side view) of the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is base schematic diagram.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
All other embodiments obtained, shall fall within the protection scope of the present invention.
The milling Woodruff key slots and keyways frock of the present embodiment as illustrated in fig. 1 and 2, including：Base 1, the support of the first support base 2, second
The 3, first addendum cone 4 of seat, the second addendum cone 5, pile crown 6 and the center positioning machine for positioning cutter for milling machines center and Woodruff key slots and keyways center
Structure 7.First support base 2 and the second support base 3 are installed on base 1, and the first addendum cone 4 is adjustably mounted at the first support base 2
On, the second addendum cone 5 is fixed on the second support base 3, and the first addendum cone 2 and the second addendum cone 3 are oppositely arranged, and pile crown 6 can move up and down
Ground is installed on the second support base 3, its axis is parallel with the axis of the second addendum cone 5, and center positioning mechanism 7 is removably mounted on
On base 1, center positioning mechanism 7 is between the first support base 2 and the second support base 3.
During work, now there is the tender of Woodruff key slots and keyways (such as：Crank) it is fixed in frock, before holding out against, tender is rotated,
Fine setting pile crown 6 up and down is adjusted at the same time, pile crown 6 is withstood eccentric orfice so that eccentric orfice center is with Woodruff key slots and keyways center in same water
In plane, tender and fixed pile crown 6 are then held out against.The cutter of milling machine is placed in the top of center positioning mechanism 7 after holding out against, center is fixed
Position mechanism 7 can be simply dial gauge, due to frock size it is known that i.e. tender hold out against after relative altitude (such as：If bottom
Seat 1 is placed on milling machine platform, and relative altitude is the opposite height with 1 bottom of base) it is also known, the ruler of cutter and dial gauge
It is very little be also it is known, behind the top of cutter centre detent mechanism 7, adjust the height of cutter, and by the reading of dial gauge come
Determine whether to reach the height that center cutter is aligned with Woodruff key slots and keyways center.After adjusting, fixed cutting tool height, the center of withdrawing is determined
Position mechanism 7, the non-standard of Woodruff key slots and keyways to be milled is changed by moving the first addendum cone 4 in the horizontal direction, and holds out against non-standard,
After holding out against, cutter is moved in the horizontal direction and mills out Woodruff key slots and keyways so that eccentric orfice center is with key slot center in same level
On, suitable for the axial workpiece 8 of eccentric structure.
Due to dial gauge contact and cutter section area all very littles, it is not easy to be aligned and withstand, in the present embodiment,
Center positioning mechanism 7 includes：Lower chamber 71, upper cavity 72, dial gauge 73, spring 74, briquetting 75, pressure cap 76 and by upper cavity 72
The exhausting-gas hole 77 being in communication with the outside, spring 74 and briquetting 75 are located in upper cavity 72,75 pressing spring 74 of briquetting, positioned at pressure cap 76
Lower section, dial gauge 73 are located in lower chamber 71, and through hole of the contact through upper cavity 72 and lower chamber 71 and spring 74 are hard
Connection.The top of pressure cap 76 is the horizontal plane of larger area, is easy to and tool contact so that cutter height adjust it is more accurate.
As shown in figure 3, base 1 is equipped with two bar shaped peaces for being respectively used to fix the first support base 2 and the second support base 3
Hole group is filled, each bar shaped mounting hole group includes two bar shaped mounting holes 11 being parallel to each other.When fastening two support bases, bar shaped
Hole 11 is so that the spacing between the first support base 2 and the second support base 3 is adjustable, to adapt to the part of different length.The two of base 1
End is equipped with gap 12, for base 1 to be fixed on milling machine platform.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
