Description

[0001] The present invention relates to a central axis line output device for a virtual cylinder,

[0001] The present invention relates to a center axis output device for a virtual cylindrical body, and more particularly, to a center axis line display device in which a line laser is emitted by an operator's operation and a second central axis line display device on one side of a cutting portion of an industrial machine tool And a center axis of the imaginary cylinder is displayed due to the intersecting vertical plane generated by the first center axis display device and the second center axis display device.

In general, the dimensioned workpieces are machined precisely to meet the requirements of the customer using various industrial machine tools.

For accurate machining of the workpiece, the origin between the workpiece and the machine tool for machining the workpiece must be set.

However, conventionally, in setting the origin, the preparatory work is inconvenient and difficult. In addition, it takes a longer time to set the origin point than an expert, or when the worker sets the positional relationship between the workpiece and the cutting tool There are many problems such as safety accidents caused by the inability to recognize.

In particular, when a safety accident occurs when setting the origin, not only personal injury but also expensive machine tools are damaged.

In order to perform a simple groove or hole work on a workpiece even if a relatively simple drilling machine is used in addition to a machine tool having excellent precision, for example, a point or a cross line is conventionally displayed on the workpiece so that the worker can visually check where the groove or hole work is required , The drill was repeated several times up and down to determine whether the drill was matched with the mark.

Therefore, as a part of solving such inconvenience and inaccuracies, a technique has been introduced for a device for marking the center of a cutting tool by using a laser, but this is also not a technique completely solving the conventional inconvenience.

As a prior art related to the center axis output device of the imaginary cylindrical body, as shown in Fig. 8 (a), "Main axis rotation center indicator of laser drilling machine" (hereinafter referred to as " , "Prior Art 1") is a cross-sectional view showing a laser beam surface irradiated from two linear-type laser modules arranged perpendicular to each other on the rotation center line of the main axis, To a spindle rotation center indicator of a drilling machine using a laser.

As another prior art, as shown in FIG. 8 (b), a "device for indicating the center of the spindle of a machine tool" (hereinafter referred to as "prior art 2") of Korean Utility Model Publication No. 20-2012-0008629 .) Shows three or more circumferential lasers on the member and adjusts the size of the circumference by using the reflecting mirror and the height adjusting switch to match the hole already punched or make it into a dot, To an apparatus for displaying the center of the spindle of a machine tool.

However, as described above, the prior art 1 to the prior art 2 are partially the same as those of the present invention in the technical field and the problem to be solved. However, the prior art 1 is inconvenient in connection with a machine tool, And there is a problem in that it is almost impossible to match the concentric circle of the main shaft and the prior art 1 with the set screw using the set screw.

In addition, the prior art 2 has a problem in that it is applied to various industrial machine tools due to its low usability as a device focused on a specific work in addition to the problems of the prior art 1.

Therefore, even if the techniques are merged based on the prior art 1 to the prior art 2, a simple merge causes a limit of the technology to derive the principle of the present invention and the configuration of the apparatus.
