Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, in an embodiment of the present invention, a right angle machining slotting tool includes a tool shank 1, and a cutting portion 2 is disposed at one end of the tool shank 1. The cutting part 2 is provided with a first cutter head 3 and a second cutter head 4 at one end far away from the cutter handle 1. The outer edge of the first cutting head 3 is the first cutting side 31 and the outer edge of the second cutting head 4 is the second cutting side 41.

One end of the cutting part 2 far away from the tool holder 1 is provided with a first side surface 21 and a second side surface 22 which are oppositely arranged; 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 plunge milling a workpiece, the first side surface 21 of the cutting portion 2 can fully support the first cutting side 31, so that the first cutting side 31 can bear a larger cutting force, as well as the second cutting side.

The cutting part 2 has a rectangular cross section, and can directly perform right-angle machining through the first tool bit 3 and the second tool bit 4, namely, a right angle is directly plunged and milled on a workpiece.

In practical application, the slotting tool can be fixed on a CNC machine tool spindle (not shown), and the CNC machine tool spindle drives the slotting tool to perform left-right slotting or up-down slotting on a workpiece so as to finish right-angle machining on the workpiece. Through fixing this slotting tool on CNC lathe main shaft can carry out right angle processing to the work piece, need not to carry out consuming time longer discharge machining, effectively promotes machining efficiency.

The slotting tool is provided with the first tool bit 3 and the second tool bit 4, so that a user can select any tool bit to perform slotting milling on a workpiece, and the service life of the slotting tool is effectively prolonged.

The inner edge of the first tool bit 3 is a first chip removal side 32, and the first chip removal side 32 is used for discharging the workpiece chips 5 cut by the first cutting side 31 on the workpiece in a specified direction. Preferably, the first chip evacuation side 32 is at an acute angle to the first cutting side 31; the first cutting side 31 lies in a plane which does not intersect the second cutting head 4. When the workpiece chips 5 cut by the first cutting side 31 on the workpiece are discharged along the first chip discharging side 32, the workpiece chips 5 are not interfered by the second tool bit 4, and the chip discharging process is ensured to be smooth.
