Description

Chamfering tool

This creation relates to a turning tool device, in particular to a turning tool structure for chamfering.

At present, the blade structure of the conventional chamfering tool is designed such that the blade back of the blade is usually set to a convex curved surface shape, and the inclined angle of the convex curved surface is substantially the same as the inclination angle of the blade portion; however, this is checked. The conventional structure has found in practical application experience that after the blade is rotated through the workpiece during the milling process, since the inclination angle of the convex surface of the blade is substantially the same as the inclination angle of the blade edge of the blade, The convex arc surface of the back of the knife will have a considerable area of friction between the workpiece after it is cut through the workpiece. The angle and curvature cannot be changed. If it is used for a long time, it must be directly replaced and the service life is short. Moreover, when using the machining, there is no place to remove the chips, which will affect the smoothness of the processing.

In view of this, the creator has improved the shortcomings of the prior art, and after years of experience in this industry, he created the creation.

In view of the above problems, the creator further studies and develops. Therefore, the main purpose of the present invention is to provide a turning tool structure. When the chamfering tool structure is used to chamfer a workpiece to be processed, The protruding V-shaped apex angle is aligned with the right-angled edge of the workpiece to be chamfered by the cutting portion, so that the right-angled edge of the workpiece to be formed forms chamfered edges with different curvatures and angles, thereby facilitating the processing effect, and With a variety of V-shaped apex angles, after a long period of use, you can remove and change the different V-shaped apex angles to achieve extended life and easy to use different chamfers.

In order to achieve the above object, the present invention provides a chamfering tool structure comprising a body having a polygonal three-dimensional structure having at least three V-shaped apex angles; and at least three chamfering turning tools, Each of the chamfering cutters is disposed corresponding to an axial extension of one of the sides of each of the V-shaped apex angles.

In some embodiments, each of the chamfer turning tools is a groove, and the two ends of the groove are respectively a cutting portion.

In some embodiments, each of the V-shaped apex angles is recessed relative to a side having the chamfering tool.

In some embodiments, the body has a perforation at the center.

In some embodiments, the body is a triangular or quadrilateral solid structure.

In view of the above, the objects and advantages of the present invention are not difficult to understand from the detailed description of the selected embodiments and the accompanying drawings.

Of course, the present invention is allowed to differ in some of the parts, or the arrangement of the parts, but the selected embodiments are described in detail in the present specification, and the construction thereof is shown in the drawings.

The technical means by which this creation is used to achieve the above objectives are described in detail below with the following implementation diagrams, which are further understood and agreed upon.

Referring also to FIGS. 1 through 10, a chamfer turning tool structure 100 includes a body 1 and at least three chamfering tools 2.

Referring to FIGS. 1 to 7, the body 1 has a quadrangular three-dimensional structure and has four V-shaped apex angles 3.

Furthermore, each chamfering tool 2 is disposed corresponding to the axial extension of one of the sides of each of the V-shaped apex angles 3, in the present embodiment, as shown in FIG. 1, the left two chamfering turning tool 2 The two chamfering cutters 2 are correspondingly disposed and connected to each other, and the two chamfering cutters 2 of the right two chamfering cutters 2 are correspondingly disposed and connected to each other.

Each chamfering tool 2 is a groove 21, and the axial ends of each groove 2 are respectively a cutting portion 22, wherein the groove 2 forms a small chamfer (as shown in Fig. 3) The angle B° shown, the curvature Rb), or the larger chamfer (such as the angle C° shown in Fig. 8, the curvature Rc).

In addition, each V-shaped apex 3 is recessed with a chip flute 4 on one side of the chamfering tool 2 .

Referring to FIG. 9 and FIG. 10 again, the body 1 has a triangular three-dimensional structure and three V-shaped apex angles 3.

Each chamfering tool 2 is disposed corresponding to an axial extension of one side of each V-shaped apex 3, and the other side is recessed with a chip flute 4; that is, an adjacent two V-shaped apex 3 The chamfering tool 2 is disposed corresponding to the chip flute 4; and each chamfering tool 2 is a groove 21, and the axial ends of the groove 21 are respectively a cutting portion 22.

Furthermore, the body 1 has a perforation 5 at the center.

According to the above structure, the chamfering turning tool structure 100 of the present invention first uses a bolt 6 to pass through the through hole 5 of the body 1 to fix the chamfering turning tool structure 100 to a shank 200, and then to pour it. One of the V-shaped apex angles 3 of the corner turning tool structure 100 protrudes outwardly from the shank 200, thereby preparing to process a workpiece 300 to be processed by the cutting portion 22 (as shown in FIG. 4). The edge of the workpiece 300 is a right angled edge.

Please refer to Figure 5 to Figure 7, when the chamfer is treated with the turning tool structure 100 When the workpiece 300 is chamfered, the outwardly protruding V-shaped apex angle 3 is aligned with the right-angled edge of the workpiece 300 to be chamfered, whereby the right-angled edge of the workpiece 300 is formed to have a curvature Rb (angle B). °) or the chamfered edge of curvature Rc (angle C°), in order to achieve the convenience of processing, and has a plurality of V-shaped apex 3, after a long time of use, you can remove and transform the different V-shaped apex 3 to Achieve extended use and easy disassembly and assembly with different chamfers.

The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the present invention, so any change in the value or substitution of equivalent elements should still fall within the scope of the present invention.
