Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

As will be further described with reference to the following specific embodiments, referring to fig. 1 to 3, the present embodiment is a numerical milling single-edge corner-cleaning slotting tool, which includes a tool shank 1, a cutting portion 2 is disposed at one end of the tool shank 1, the cutting portion 2 is in a rib-shaped structure, the length direction of the cutting portion 2 and the length direction of the tool shank 1 are kept coincident, and a first inclined surface 21 is disposed on one side of the cutting portion 2 close to a tool nose; the cutting part 2 is provided with a second surface 22 deviating from the first inclined surface 21, the front end of the cutting part 2 is provided with a second inclined surface 23, and two ends of the second inclined surface 23 are respectively connected with the first inclined surface 21 and the second surface 22 to form a blade structure. Specifically, the utility model discloses when using, through packing into machining center's tool magazine with this single-edged angle clearance slotting tool, can adorn on machining center's main shaft through its handle of a knife 1 part, it is fixed with the work piece clamping, accomplish preliminary milling flutes mouth processing by milling cutter, change this single-edged slotting tool into again and use, utilize numerical control system to fix a position vertical line of walking in work piece four corners and in order to accomplish the angle clearance operation, this cutting edge is when using, only can clear the angle to the unilateral of processing notch, the slotting tool needs to change the cutting edge direction and just can process the right angle of notch opposite side, therefore, first inclined plane 21 is in the course of working, it leans on one side of the inside of notch all the time; in addition, the slotting tool is vertical man-hour, can have the gap between first inclined plane 21 and the notch inner wall, and cutting part 2 has big inclined plane chip removal structure, and the chip removal is smooth, and to sum up, this slotting tool has avoided work piece notch right angle to add man-hour, need carry out equipment transfer processing, make full use of machining center's machining precision, higher than traditional slotting machine precision, and compare the electric machining process, the processing cost is lower, weak point consuming time, efficient.
