Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Referring to FIGS. 1-4 , in an embodiment of the present invention, a right-angle machining insert includes a handle 1 , and one end of the handle 1 is provided with a cutting portion 2 . A first cutting head 3 and a second cutting head 4 are provided on the end of the cutting portion 2 away from the tool handle 1 . The outer edge of the first cutter head 3 is the first cutting side 31 , and the outer edge of the second cutter head 4 is the second cutting side 41 .

The end of the cutting portion 2 away from the shank 1 has a first side surface 21 and a second side surface 22 arranged oppositely; the first cutting side 31 is located on the first side surface 21 , and the second cutting side 41 is located on the second side surface 22 . When the first cutting side 31 is plunging the workpiece, the first side 21 of the cutting part 2 can fully support the first cutting side 31, so that the first cutting side 31 can bear a larger cutting force, and the second cutting side The same is true.

The cross section of the cutting portion 2 is rectangular, and the first cutter head 3 and the second cutter head 4 can directly perform right-angle machining, that is, the right angle can be directly plunged and milled on the workpiece.

In practical application, the plunger can be fixed on the spindle of the CNC machine tool (not shown), and the spindle of the CNC machine tool can drive the plunger to perform left and right plunge milling or up and down plunge milling of the workpiece to complete right-angle machining of the workpiece. By fixing the plunger on the spindle of the CNC machine tool, right-angle machining of the workpiece can be performed without the need for time-consuming electrical discharge machining, which effectively improves the machining efficiency.

The plunger is equipped with a first cutter head 3 and a second cutter head 4, and the user can choose any cutter head to plunge-mill the workpiece, which effectively improves the service life of the plunger.

The inner edge of the first cutter head 3 is the first chip removal side 32 , and the first chip removal side 32 is used to discharge the workpiece chips 5 cut off by the first cutting side 31 from the workpiece along a predetermined direction. Preferably, the included angle between the first chip removal side 32 and the first cutting side 31 is an acute angle; the plane where the first cutting side 31 is located does not intersect with the second cutter head 4 . When the workpiece chips 5 cut off by the first cutting side 31 are discharged along the first chip discharge side 32 , the workpiece chips 5 will not be collided by the second cutter head 4 to ensure smooth chip removal process.
