The present invention relates to a micro-movement control device of the metal workpiece tool length, and more particularly, to the movement of the tool length by fine adjustment of the insert adjustment screw coupled with the adjustment screw to the insert fixed to the milling and cutting tools to process the workpiece It relates to a device that can be finely adjusted.

In general, milling and cutting tools are tools used for cutting and boring cutting workpieces that have a cutting edge, i.e., a tool having a cutting edge, in a straight line while rotating, and are used in one of the cutting methods by pickling. These cutting tools comprise a cutting insert having a cutting edge as described above and a body for fixing the cutting insert.

As one of the methods of fixing the cutting insert to the body, the working shaft having a separate fixed shaft is integrally formed. In this method, the insert can be easily exchanged when necessary, which is currently used in all cutting tool fields. Has been used to fix the insert using a wrench bolt on one side of the fixed shaft for easy replacement, but the above clamping devices are quite inconvenient to keep the cutting insert within the minimum even if there is no adjustment device. There was a ham.

That is, in order to adjust the cutting edge in the milling tool and the cutting tool using all conventional clamping mechanisms, the insert or assembly state must be released, and precise length adjustment is not easy in this process.

The present invention is to solve the conventional problems as described above, the object of the present invention is a metal that can finely adjust the length of the cutting edge insert while maintaining the assembled state of the insert fixed to the fixed axis of the milling tool and cutting tool It relates to a fine movement control device of the workpiece tool length,

In order to achieve the above object, to form an adjustment groove formed with a screw thread on one side of the fixed shaft or the operating shaft for fixing the insert, the adjustment groove accommodates the adjustment screw, the adjustment screw and the insert adjustment screw formed integrally with the insert and It is to provide a micro-movement control device for the length of the metal workpiece, characterized in that configured to be able to adjust the length of the insert adjustment screw by rotating the adjustment screw while operating in engagement with each other.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment of the present invention as follows.

1 is a perspective view of a state in which the main part of the present invention is assembled, and FIG. 2 is a cross-sectional view of the main part of the present invention assembled, and FIG. 3 is a partial cross-sectional view of an enlarged state by extracting the main part of the present invention.

First, as shown in FIG. 1, the tool body 10 is composed of a fixed shaft 12 having an insert 13 and an actuating shaft 11 for transmitting rotational force, thereby inserting the insert 13 into the fixed shaft 12. An insert fixing screw 17 that can be firmly fixed is formed, and the insert fixing screw 17 is fixed to the outside of the fixed shaft 12 as shown in FIGS. 1 and 2, but the configuration is the same as in the conventional method. Or similar.

On the other hand, a portion of the insert adjusting screw 16 is formed at a predetermined position of the insert 13 accommodated inside the fixed shaft 11, and the insert adjusting screw 16 is engaged with the adjusting screw 15 assembled from the outside. It can be rotated in a state, the adjustment screw 15 is inserted into the adjustment groove 14 is in a state that is combined with the rotating ball 18 to rotate.

In addition, by using a separate hexagon wrench (not shown) to operate the adjusting screw 15, while operating the adjusting screw 15 through the hexagon wrench to start the fine movement.

In the above situation, the adjusting screw 15 and the insert adjusting screw 16 are preferably formed by separate threads, and the hexagonal wrench (not shown) is used for the adjusting screw 15 as shown in FIGS. 2 and 3. The length of the insert 13 can be adjusted. At this time, if the hexagon wrench is rotated in the right direction, the adjusting screw 15 is moved forward, and the insert adjusting screw 16 is also moved, so that the length of the tool in the state of vertical movement is possible. Adjustment is possible.

And after length adjustment, the insert fixing screw 17 can be fixed again and the state can be firmly maintained.

As for the working force here, when the adjusting screw (15) is M6 X 0.75 (pitch), 0.75mm moves at 360 ° rotation (1 rotation), so 0.002mm moves at 1 ° rotation, so it is precisely adjusted within 2u. This is possible.

In addition, the fixing shaft 12 is fastened to the insert fixing screw 17 to securely insert the insert 13, by using the insert fixing screw 17 to prevent backlash and fixation of the adjustment screw 15 Therefore, even if the distribution force P generated during cutting is large, the insert 13 does not move.

Referring to the operation and effects of the present invention made of the above configuration in detail as follows.

First, as shown in FIGS. 1 and 2, there is an operating shaft 11 and a fixed shaft 12 constituting the tool body 10, and the insert 13 is fixed to the fixed shaft 12, wherein the insert ( 13 may be fixed by a process of coupling the insert fixing screw 17, while adjusting screws in the adjusting groove 14 formed between the operating shaft 11 and the fixed shaft 12 as shown in Figs. (15) is combined.

The adjusting screw 15 is integrally engaged with the portion of the insert adjusting screw 16 formed on the insert 13, so that the user rotates the adjusting screw 15 using a hexagon wrench (not shown). The length of the adjustment can be made, in which the adjustment screw 15 and the insert adjustment screw 16 is to be operated as shown in Figs.

That is, while rotating the adjusting screw 15 integrally engaged with the insert adjusting screw 16, the length of the insert 13 coupled to the fixed shaft 12 can be finely adjusted, resulting in the fixed shaft 12. The formed insert fixing screw 17 is to facilitate the movement of the insert 13 by using a hexagon wrench, and then finely adjust the length of the insert 13 while rotating the adjustment screw 15.

After adjusting the length of the insert 13, the operator can fix the insert fixing screw 17 to its original position again, and operate the milling and cutting tool which is a machine tool by using the adjusted insert to process the workpiece.

In addition, in the case of replacing a new insert, it may be fastened and adjusted through the above-described process.

Embodiment described above is configured to help the understanding of the present invention, it is only one embodiment that can be applied to the present invention, the scope of the present invention is not limited to the above-described embodiment.

In addition, it is possible for those skilled in the art to which the present invention pertains to various substitutions, modifications and changes within the scope without departing from the technical spirit of the present invention, the shape and structure of each component may be modified and carried out. It can be.

According to the present invention of the above configuration there is an advantage that can be easily used according to the characteristics of the workpiece as well as the length can be adjusted even in the insert inserted into the fixed shaft.

In addition, since the length of the insert can be precisely adjusted, the surface roughness of the workpiece can also be expected to be superior to that of the conventional art, and there is no need to separately maintain and repair the adjusting screw.
