Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figures 1-15, the utility model bolt head regular polygon milling tool, including firm banking 1, tool assembly 2
And nut model module；
Nut model module one end is polygon nut 31, and the other end is protecting sleeve for thread 32, the shape of polygon nut 31
Shape needs the regular polygon that is milled into consistent with to milling screw nut 52, as act to milling screw nut 52 needs to mill in figure
Be whittled into square, polygon nut 31 is exactly square, and protecting sleeve for thread 32 is hollow tubular, protecting sleeve for thread 32 be equipped with to
The depth of the internal screw thread that milling screw thread matches, protecting sleeve for thread 32 is greater than to milling screw screw rod total length, to milling
Screw screw rod can entirely screw in protecting sleeve for thread 32, and the outside diameter of protecting sleeve for thread 32 is B1, most to milling screw
Major diameter is B2, has protection step 51 to milling screw belt sometimes, is at this time to protect platform to the maximum gauge B2 of milling screw
The diameter of rank 51, the outside diameter B1 of protecting sleeve for thread 32 are more than or equal to the diameter B2, Fig. 6 of protection step 51, are shown in 7
The straight B1 diameter of the outer circle of protecting sleeve for thread 32 is equal to the diameter B2 of protection step 51.Firm banking 1 is fixedly connected with milling machine table；
Tool assembly 2 is cut by cuboid pin, and 2 one side of working body of cuboid is fixedly connected as bottom surface with firm banking 1, cuboid
2 one side level of tool assembly offer nut model fixing groove 21, as shown in figure 8, when nut model fixing groove 21 is slot, slot
Wide A1 is equal with the back gauge A2 of polygon nut 31, and polygon nut 31 can just be caught in nut model fixing groove 21 at this time,
Nut model fixing groove 21 plays the role of limitation rotation to polygon nut 31, as shown in figure 9, nut model fixing groove 21 is
As figure it is step-like when, polygon nut 31 is penetrated after stepped hole 22 and is in close contact on one side with step, i.e. 22 major diameter of stepped hole
The distance of central point to ledge surface is equal to A2/2.Vertical 21 slot bottom level of nut model fixing groove is opened up through working body 2
Stepped hole 22, stepped hole 22 1 are open on the slot bottom of nut model fixing groove 21, another opening tool assembly 2 opposite in slot bottom
On side, stepped hole 22 has size diameter, and major diameter is identical as the outside diameter of protecting sleeve for thread 32, and major diameter depth is less than etc.
In 32 length of protecting sleeve for thread, guarantee to penetrate after stepped hole 22 with the nut model module after milling screw association to milling spiral shell
The nut of nail can enter in the minor diameter of stepped hole 22, and 22 minor diameter of stepped hole is identical as the diameter to milling screw nut 52,
Minor diameter depth is more than or equal to the thickness to milling screw nut 52, guarantees that nut is not convex outside tool assembly 2.It is solid with nut model
Determine level on opposite 2 another side of tool assembly of slot 21 and offers the first feed slot 23 and the second feed slot 24, the first feed
Slot 23 passes through the top of 22 minor diameter of stepped hole opening, and the second feed slot 24 passes through the lower part of 22 minor diameter of stepped hole opening, into
