Description
Technical field
The present invention relates to metal cutting process field, more particularly to a kind of rotary cutting tool.
Background technology
In the prior art, if with the manufacturing development of intermetallic composite coating in working angles, the requirement to workpiece surface quality
More and more higher, the rotary cutter with multiple cutting tips is in cutting operation, if the end of cutting tip and sidepiece positioning
Precision is not high, by the service life of very big reduction machined surface quality and cutting tip, in order to improve machined surface quality, cutting
The end of blade and sidepiece are required to positioning precision as high as possible, therefore, the end of each cutting tip of rotary cutter or
The bounce of sidepiece required control within 0.001mm, due to cutter hub and cutting tip size by manufacturing capacity limited with
And the presence of fit-up gap, bounce be extremely difficult to it is so high-precision require, in order to meet processing needs, conventional mode be
Bounce adjustment structure is set at each cutting tip, and bounce adjusting means of the prior art is all that cutting tip is arranged on into knife
On seat, the purpose that axially or radially size is adjusted is reached by different Principles of Regulation adjustment, in addition, in some occasions, such as
In high-speed machining process, set tool rest to play a part of protecting cutter hub, i.e., can when cutter is impaired by larger impulsive force
Tool rest is only changed without changing whole cutter hub, but is due to the presence of tool rest, the positioning side of blade is fixed with tool rest contact
Position, diameter or height dimension when often making the diameter or short transverse size of cutter tool rest is not installed much larger than cutter so that
The use scope of cutter is limited.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art to be made as there is provided a kind of with the small of tool rest
Sized knife and rotary cutting tool applied widely.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of rotary cutting tool, including cutter hub, tool rest and cutting tip, the head outer of the cutter hub are provided with cutter groove,
The tool rest is arranged in the cutter groove by connector, and the tool rest is provided with blade installation slot, and the cutting tip passes through
Fastener is arranged in the blade installation slot, and the cutting tip includes bottom locating surface, the first side-locating face and the second side
Locating surface, the bottom locating surface contacts positioning with tool rest, and first side-locating face contacts positioning, described with the tool rest
Two side-locating faces contact positioning with the cutter hub.
It is used as the further improvement of above-mentioned technical proposal：
The cutter groove includes bottom supporting face, rear support face, collateral bearing surface and from the side bearing towards the recessed of indent
Face, the tool rest includes bottom surface, rear end face and medial surface, and the bottom surface contacts positioning, the rear end with the bottom supporting face
Face contacts positioning with the rear support face, and the medial surface is embedded in the cutter hub, second side-locating face and the side bearing
Face contact positioning.
The bottom supporting face is recessed provided with the strip that multiple adjustment directions along cutting tip are set, on the bottom surface
Provided with the recessed corresponding strip projected parts of the strip on bottom supporting face.
The rear support face is recessed provided with multiple strips, and the rear end face is provided with recessed with strip on rear support face
Corresponding strip projected parts.
The strip is recessed and strip projected parts sections are trapezoidal.
The tool rest also includes adjustment mechanism, and the adjustment mechanism includes adjusting screw and the adjustment block with elastic groove, institute
State the first side-locating face to contact with the adjustment block, the depth adjustment that the elastic groove is screwed in by adjusting the adjusting screw is cut
The position of paring blade.
Compared with prior art, the advantage of the invention is that：
（1）The rotary cutting tool of the present invention, tool rest is arranged in cutter groove, and cutting tip is arranged on the blade peace on tool rest
In tankage, the second side-locating face directly contacts positioning with cutter hub, rather than is contacted with tool rest, therefore in the second side-locating face and knife
On the direction of body contact, the size of cutter will not increase because tool rest is provided with, relative to two of blade in the prior art
Side contacts positioning with tool rest, can reduce rotary cutting tool chi on the direction that the second side-locating face is contacted with cutter hub
It is very little, specifically, can be by rotary cutting if the direction that the second side-locating face is contacted with cutter hub is rotary cutting tool radial direction
The cutter hub diameter of cutter is set to smaller value, expands the use scope of rotary cutting tool, or certain in cutter hub diameter
In the case of, the quantity of set blade installation slot and cutting tip can be increased, the machining accuracy of rotary cutting tool is improved
And processing efficiency；If the direction that the second side-locating face is contacted with cutter hub is that rotary cutting tool is radially rotary cutting tool axle
To can then reduce the height dimension of rotary cutting tool, can equally expand the use scope of rotary cutting tool.It is i.e. of the invention
Using simple structure, rotary cutting tool radial dimension or axial height with tool rest in the prior art are solved big, applicable
The problem of scope is limited.
（2）The tool rest bottom of the present invention is recessed provided with the strip that multiple adjustment directions along cutting tip are set, and cutter groove
Bottom surface be provided with the recessed corresponding strip projected parts of the strip on tool rest bottom supporting face, deposited when between connector and tool rest connecting hole
At gap, it can be avoided by the recessed cooperation between strip projected parts of strip collateral due to tool rest caused by stress and cutter groove
The change of actual location angle between bearing surface；And avoid the change of actual location angle between the collateral bearing surface due to tool rest and cutter groove and
The angle change of caused blade horizontal direction cutting edge and cause influence cutting effect.
