Abstract
The utility model discloses an annular groove milling cutter. The annular groove milling cutter comprises a cutter rod, wherein one end of the cutter rod is connected with a supporting plate; the supporting plate is U-shaped; cutting tools are arranged at the two ends of the supporting plate; the two cutting tools are arranged in a mirror image shape and are distributed in a symmetrical manner; each cutting tool is provided with an arc-shaped supporting part and an arc-shaped cutting part; the arc-shaped cutting parts are fixedly arranged on the arc-shaped supporting parts. Due to the adoption of the annular groove milling cutter, a whole annular groove can be machined and molded for one time; the annular groove milling cutter has the advantages of high efficiency and low cost.
Description
Technical field
The utility model relates to a kind of cannelure milling cutter.
Background technology
In the time of the operation of Machining Arc groove, first to use cannelure milling cutter to mill out rectangular channel at surface of the work, re-use rose cutter and further rectangular channel is processed into arc-shaped slot, in process, need to change cutter tool setting again, like this, not only waste time and energy, operating efficiency is lower, and due to needs again tool setting, easily produce error, thereby affect machining accuracy.Plant arc groove milling cutter, be made up of cutter head, neck and handle of a knife, described handle of a knife is staight shank, and described cutter head is provided with four cutting edges, and the angle between each cutting edge is 90 degree, and the sword face of described cutting edge is circular arc.But this arc groove milling cutter can only process the groove of circular arc, cannot process the annular groove of whole annular.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of cannelure milling cutter, and the utility model can the whole cannelure of time processing moulding, has advantages of that efficiency is high, cost is low.
The technical scheme solving the problems of the technologies described above is as follows:
Cannelure milling cutter, comprise knife bar, one end of knife bar connects a gripper shoe, this gripper shoe is U-shaped, at the two ends of gripper shoe, a cutting tool is set respectively, two cutting tools are symmetrical mode after with mirror image to be arranged, cutting tool has an arc support and arc milling portion, and arc milling portion is fixed in arc support.
Adopt such scheme, it is U-shaped that gripper shoe is, and at the two ends of gripper shoe, a cutting tool is set respectively, and two cutting tools are symmetrical mode after with mirror image and arrange, cutting tool has an arc support and arc milling portion, and arc milling portion is fixed in arc support.By two cutting tools and arrangement thereof, in the time that knife bar drives supporter to rotate, the walking path of two cutting tools forms a circle, by the shear action of cutting tool, thereby on workpiece to be machined, forms a cannelure.The cannelure of this time processing moulding, has advantages of that working (machining) efficiency is high and cost is low.
Further, described arc milling portion is provided with the first cutting edge, and this first cutting edge is the chamfering of periphery and the axial end of arc milling portion, and the gradient of this chamfering is 2.5-3.5 degree.By the first cutting edge, can on workpiece, cut rapidly required cannelure.
Further, described arc support is provided with the second cutting edge, the periphery that this second cutting edge is arc support and the chamfering of axial end, and the gradient of this chamfering is 40-50 degree.By the second cutting edge, can process the oral area of cannelure, thereby make the oral area of cannelure form chamfering.
Further, described knife bar and gripper shoe are provided with the Cooling Holes being interconnected.By input cooling fluid in Cooling Holes, the mode of logical heat transfer, can accelerate to absorb the heat producing in working angles, thereby guarantee the service life of cutting tool.
Brief description of the drawings
Fig. 1 is the front view of cannelure milling cutter of the present utility model;
Fig. 2 is the A portion enlarged drawing in Fig. 1;
