More specifically, the cross section of the first fixture block is square, tapered structure of second fixture block.
More specifically, the cavity inner wall symmetrically offers two pair of a groove in the corresponding position of the first fixture block side surrounding,
Corresponding second screw hole is offered in groove corresponding position and is connected to groove on the outside of the knife handle, and each inside grooves are equal
It is provided with movable sliding block, the second screw for fine tuning is bolted in second screw hole.
More specifically, the knife handle is aluminum alloy material, and the cutter head is made of high rigidity wolfram steel material.
More specifically, the knife handle is in cylindrical structure, and the skid resistance strip for avoiding skidding is provided on the outside of the knife handle.
There are advantage and good effects for the utility model: the utility model be a kind of interchangeable bit milling cutter, by
Holding section is arranged in cutter head one end, then holding section is fixedly connected in the cavity of knife handle by first screw on top, according to need
It replaces different model cutter head or when blade part is worn replaces cutter head, be not required to entire cutter and replaced, improved
The utilization rate of resource；In addition the second screw and sliding block are set in holding section surrounding, the contraposition of cutter head can be finely adjusted, guaranteed
Knife handle is Chong Die with the central axis of cutter head, guarantees the machining accuracy of workpiece.
Detailed description of the invention
Fig. 1 is the positive sectional view of embodiment milling cutter.
Fig. 2 is the three-dimensional cutaway view of knife handle.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing, but the utility model
Embodiment is not limited to this.
As shown in Figure 1 and Figure 2, embodiment is a kind of milling cutter of interchangeable bit, including knife handle 1 and detachable with knife handle 1
The cutter head 2 of formula connection, the cutter head 2 include interconnecting piece 21 and the blade part 22 for being fixedly connected on 21 bottom end of interconnecting piece, the company
Socket part 21 includes a connecting rod 23 and the holding section 24 for being fixed at 23 top of connecting rod, and the holding section 24 includes being located at lower end
First fixture block 25 and the second fixture block 26 for being fixed at 25 top of the first fixture block, the top middle portion of second fixture block 26 are opened
Equipped with the first screw hole 261 for fixing, the knife handle 1 offers the cavity 3 for accommodating holding section 24, the knife handle 1
Top middle portion be provided with deep gouge hole 4 and communicated with cavity 3, holding section 24 is fixed on by the first screw 5 by the deep gouge hole 4
In the cavity 3 of knife handle 1.
More specifically, in embodiment, the cross section of the first fixture block 25 is square, second fixture block 26 tapered knots
Structure also offers the cavity 3 of shape matching in the bottom of knife handle 1 accordingly and is screwed onto the second fixture block 26 by the first screw 5
The first screw hole 261 in, wherein the square body structure of the first fixture block 25 prevented also from rotation when holding section 24 have skidded and
Cause the situation of the shakiness of cutter head 2.
More specifically, 3 inner wall of cavity the corresponding position of 25 side surrounding of the first fixture block symmetrically offer two pairs it is recessed
Slot 6,1 outside of knife handle offers corresponding second screw hole 7 in 6 corresponding position of groove and is connected to groove 6, each described recessed
It is provided with movable sliding block 8 inside slot 6, the second screw 9 for fine tuning is bolted in second screw hole 7；Cutter head 2
It is fixed in knife handle 1 by the first screw 5 it is possible that the case where deflection, by adjusting the first spiral shell of 25 surrounding of the first fixture block
5 are followed closely to drive sliding block 8, the contraposition of cutter head 2 can be finely adjusted, guarantees that knife handle 1 is Chong Die with the central axis of cutter head 2, also guarantees work
