Abstract

The invention relates to a circular ring slotting cutter. The circular ring slotting cutter comprises a cutter bar, wherein one end of the cutter bar is provided with a cutter bit extending axially along the cutter bar, an end surface cutting edge, a thread cutting edge and an orifice inner wall cutting edge are arranged on the cutter bit, the end surface cutting edge is arranged at the free end part of the cutter bit, the thread cutting edge is arranged on the circumferential surface of the cutter bit, the orifice inner wall cutting edge is arranged on the outer circumferential surface of the cutter bit, and one end of the orifice inner wall cutting edge is extended to the cutter bar. The circular ring slotting cutter can process and mold a thread hole once and has the advantages of simple procedures, high production efficiency and low cost.

Description

Annular groove milling cutter
Technical field
The present invention relates to a kind of annular groove milling cutter.
Background technology
When the operation of Machining Arc groove, annular groove milling cutter first will be used 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 and tool setting again, like this, not only waste time and energy, operating efficiency is lower, and due to needs again tool setting, easy generation error, thus 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, the annular groove of whole annular cannot be processed.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of annular groove milling cutter, the present invention can the shaping whole cannelure of time processing, has the advantage that efficiency is high, cost is low.
The technical scheme solved the problems of the technologies described above is as follows:
Annular groove milling cutter, comprise knife bar, one end of knife bar connects a straight fagging, this gripper shoe is U-shaped, a cutting tool is set respectively at the two ends of support bar, two cutting tools are arranged in mode symmetrically after mirror image, and cutting tool has an arc support and arc milling portion, and arc milling portion is fixed in arc support.
Have employed such scheme, gripper shoe is U-shaped, arranges a cutting tool at the two ends of support bar respectively, and two cutting tools are arranged in mode symmetrically after mirror image, 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, when knife bar drives supporter to rotate, the walking path of two cutting tools forms a circle, by the shear action of cutting tool, thus forms a cannelure on workpiece to be machined.The cannelure that this time processing is shaping, has the high and advantage that cost is low of working (machining) efficiency.
Further, described arc milling portion is provided with the first cutting edge, and this first cutting edge is the periphery in arc milling portion and the chamfering of axial end, and the gradient of this chamfering is 2.5-3.5 degree.By the first cutting edge, required cannelure can be cut rapidly on workpiece.
Further, described arc support is provided with the second cutting edge, and this second cutting edge is the periphery of 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, thus make the oral area of cannelure form chamfering.
Further, described knife bar and gripper shoe are provided with the Cooling Holes be interconnected.By inputting cooling fluid in Cooling Holes, by the mode of heat trnasfer, can accelerate to absorb the heat produced in working angles, thus guaranteeing the service life of cutting tool.
Accompanying drawing explanation
Fig. 1 is the front view of annular groove milling cutter of the present invention;
Fig. 2 is the A portion enlarged drawing in Fig. 1;
Fig. 3 is the left view of Fig. 1;
In accompanying drawing, 1 is knife bar, and 2 is gripper shoe, and 3 is arc support, and 4 is arc milling portion, and 5 is the first cutting edge, and 6 is the second cutting edge, and 7 is Cooling Holes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
With reference to Fig. 1, annular groove milling cutter of the present invention, comprises knife bar 1, and one end of knife bar 1 connects a straight fagging 2, and this gripper shoe 2 is U-shaped, arranges a cutting tool at the two ends of support bar 2 respectively, and two cutting tools are arranged in mode symmetrically after mirror image.Cutting tool has an arc support 3 and arc milling portion 4, and arc milling portion 4 is fixed in arc support 3.Described arc milling portion 4 is provided with the first cutting edge 5, and this first cutting edge 5 is the periphery in arc milling portion and the chamfering of axial end, and the gradient of this chamfering is 2.5-3.5 degree.Described arc support 3 is provided with the second cutting edge 6, and this second cutting edge 6 is the periphery of arc support and the chamfering of axial end, and the gradient of this chamfering is 40-50 degree.Described knife bar 1 and gripper shoe 2 are provided with the Cooling Holes 7 be interconnected.
