Description

[0001] FLY-CUT WHEEL ASSEMBLY [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fly-cut wheel assembly, which is a tool used for chamfering a workpiece such as a plate, and more particularly, to a fly-cut wheel assembly capable of easily setting an angle of inclination and a circumference angle of a bite.

Generally, the flywheel assembly is widely used to ensure uniformity of cutting angle when machining side faces and chamfering of a workpiece, and consider noise, vibration, surface machining effect, bite wear and service life during machining.

Therefore, conventionally, a registered and patented technology has been developed in Chinese patent application ZL201420077050.5, which is a structure for adjusting the circumferential angle of the bite.

However, in the prior art, it is merely a technique of adjusting the angle in the circumferential direction of the cutting tool. Therefore, a cutting tool having a different cutting edge angle is applied according to the angle of the side machining surface of the workpiece. The tips are formed in a combined shape, and it is very inefficient to produce the bite with different angle of the cutting edge.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a method and apparatus for cutting a bobbin, The present invention provides a flywheel assembly capable of easily setting a circumferential angle.

In order to accomplish the above object, the present invention provides a flywheel wheel assembly which is mounted on a spindle of a machine tool and is formed by side machining or chamfering of a workpiece, wherein a wheel is installed on a lower portion of a main holder, Wherein one or more bite holder mounting portions formed on the wheel are formed, and a bite is provided on the inner surface of the bite holder having an inner inclined surface by a bite-bite bolt, and the bite holder is fixed to the bite holder And a flywheel assembly mounted on the mounting portion.

A plurality of arcuate slots are formed in the bite holder and the bite holder is fastened to the wheel through a slot of the bite holder so that the bite holder is installed in the bite holder mounting portion of the wheel, A plurality of screw holes penetrating through the bite holder mounting portion are formed on the wheel so that the circumferential angle adjusting bolts are respectively fastened to the screw holes of the wheel and the distal end portions of the circumferential angle adjusting bolts are brought into close contact with the side surfaces of the bite holder, And adjusting the circumferential angle of the bite holder by adjustment of the bolt.

Since the fly-cut wheel assembly according to the present invention can adjust the inclination angle of the bite by replacing the bite holder having a plurality of inner inclined surfaces coupled to the bite holder insertion groove of the wheel, There is an advantage that the inclination angle of the bite can be easily set according to the angle of the machined surface or the chamfer angle of the workpiece.

Also, the circumference angle of the bite can be easily adjusted by rotating the bite holder using the circumferential angle adjusting bolt.

1 is an exploded cross-sectional view of a flywheel assembly according to the present invention coupled to an example holder.
Figure 2 is an exploded cross-sectional view of a flywheel assembly in accordance with the present invention that is coupled to a holder of another example;
3 is a sectional view taken along the line A-A in Fig.
4 is a cross-sectional view showing a bite holder having various inner inclined surfaces;

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Figs. 1 to 3 are views showing a fly-cut wheel assembly according to the present invention, wherein the fly-cut wheel assembly is mounted on a spindle (not shown) of a machine tool (not shown) to process the workpiece side or chamfer.

That is, the fly-cut wheel assembly according to the present invention is characterized in that the wheel 2 is installed on the lower portion of the main holder 1 which is detached from the spindle, and one or more bite holder mounting portions 2a formed on the wheel 2 are provided with a bite holder 3, and the bite 4 is attached to the bite holder 3 by the bite 5.

In other words, one or more bite holder mounting portions 2a formed on the wheel 2 are formed, and the bite holder 3 has an internal inclined surface 3a formed therein, The inclination angle of the bite 4 is determined by the internal inclined surface 3a of the byte holder 3. [

Therefore, according to the present invention, it is possible to manufacture the bite holder 3 having various angles of the inner inclined surface 3a as shown in Fig. 4 without manufacturing the bite 4 having the diamond tip bonded to the cemented carbide in various forms, It is possible to adjust the angle of inclination of the bite 4 coupled with the inner inclined surface 3a of the bite holder 3 by manufacturing various types of the bite holder 3 made of a metal material.

On the other hand, since it is necessary to adjust the circumference angle of the bite 4, in the present invention, as shown in Fig. 3, a plurality of arc-shaped slots 3b are formed in the bite holder 3, 6 is fastened to the wheel 2 through the long hole 3b of the bite holder 3 so that the bite holder 3 is installed on the bite holder mounting portion 2a of the wheel 2, A plurality of screw holes 2b are formed in the wheel 2 so as to pass through the bite holder mounting portion 2a of the wheel 2 and the circumferential angle adjusting bolt 7 is screwed into the screw hole 2 of the wheel 2. [ Respectively.

The distal end of the circumferential angle adjusting bolt 7 is brought into close contact with the side surface of the bite holder 3 to adjust the circumferential angle of the bite holder 3 by adjusting the circumferential angle adjusting bolt 7, The circumferential angle of the bite 4 can be smoothly adjusted.

In particular, in order to conveniently install the byte holder 3 on the wheel 2, a rotation center insertion protrusion 3b is formed to protrude from the rotation center of the upper surface of the byte holder 3, The rotation center insertion portion 2c into which the rotation center insertion protrusion 3b of the wheel 2 is inserted is formed in the byte holder mounting portion 2a of the wheel 2. [

The operation of the flywheel assembly according to the present invention is as follows.

The operator adjusts the circumferential angle of the bite holder 3 and the bite 4 by adjusting the position of the distal end of the circumferential angle adjusting bolt 7 by rotating the circumferential angle adjusting bolt 7 in accordance with the cutting angle of the workpiece The degree of projection of the tip end of the bite 4 and the circumferential angle of the cutting edge of the bite 4 are adjusted.

In order to adjust the angle of inclination of the bite 4 in the present invention, after the bite holder 5 is loosened to separate the bite holder 3, the inner inclined surface 3a, which is necessary for adjusting the inclination angle of the bite 4, The bite 4 is arranged in the bite holder 3 provided with the bite 5 and the bite 4 is connected to the wheel 2.

Here, in the present invention, it is possible to easily adjust the angle of inclination of the bite 4 according to the replacement of the bite holder 3 by manufacturing a plurality of bite holders 3 in which the inner inclined faces 3a are formed in various ways.

Therefore, by adjusting the angle of inclination of the bite 4 with the operation of replacing the bite holder 3 as a simple structure, the angle of inclination of the bite 4 coupled to the bite holder 3 is adjusted to the angle of the cutting surface of the workpiece The fly cut wheel assembly of the present invention can be rotated by the spindle to smoothly cut the workpiece.
