Description
Technical field
Machining tool technical field is the utility model is related to, especially a kind of rotary milling tools.
Background technology
Its blade of existing rotary milling tools and tool rest are fixed by screw, due to blade very little, so blade
On be all to be fixed by single fixing screws, when milling cutter is in high speed rotation state, blade bears very big centrifugal force；
When blade is in Milling Process workpiece, blade is subjected to very big centrifugal force, and bears very big Milling Force, in order to
Ensure the fix stably of blade, so the requirement to screw is very high, so as to add use cost.
Utility model content
The technical problems to be solved in the utility model is：It is larger in order to solve the power that the screw of existing fixed blade bears,
Requirement to screw is very high, and the problem of so as to add use cost, the utility model provides a kind of rotary milling tools, passes through
Transverse concave groove matches with lateral projection, and longitudinal projection matches with longitudinal fluting, is coordinated by raised with groove to bear
Blade centrifugal force, so as to the power that the screw greatly reduced is born, ensure that blade can be fixed in general screw, and
The fix stably of blade can be ensured.
Technical scheme is used by the utility model solves its technical problem：A kind of rotary milling tools, including tool rest, blade
And fixing screws, tool rest are circumferentially uniformly provided with chip area, the side of chip area is provided with the fixing groove of fixed blade,
Lateral projection, the projection of longitudinal direction and the first fixing threaded hole are set in the fixing groove；
The blade includes the contact surface that match with fixing groove, the contact surface provided with transverse concave groove, longitudinal fluting and
Second fixing threaded hole；
The transverse concave groove matches with lateral projection, and longitudinal projection matches with longitudinal fluting, the fixation
Blade is fixed on tool rest by screw through the second fixing threaded hole and the first fixing threaded hole.
Specifically, the contact surface is square, and the transverse concave groove and longitudinal fluting are respectively perpendicular to the four of contact surface
Bar side.
Specifically, the transverse concave groove and longitudinal fluting are respectively one.
Further, the intersection point of the transverse concave groove and longitudinal fluting is at the center of contact surface.
Further, the four edges of the blade are respectively equipped with blade.
The beneficial effects of the utility model are：The utility model provides a kind of rotary milling tools, is matched somebody with somebody by projection with groove
Close to bear the centrifugal force of blade, so as to the power that the screw greatly reduced is born, ensure that in general screw can enter to blade
Row is fixed, and can ensure the fix stably of blade, so as to reduce cost；The intersection point of transverse concave groove and longitudinal fluting is connecing
The center of contacting surface, raised and matching grooves can be ensured when exchanging the position of blade.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of rotary milling tools of the present utility model.
In figure：1. tool rest, 2. blades, 3. chip areas, 4. fixing grooves, 21. contact surfaces, 22. transverse concave grooves, 23.
