BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to drilling. In the tapping machine, in order to automate the drilling and tapping of the work, drilling the target work position of the work. Drilling to store the movement position data of both tapping means. The present invention relates to a teaching method for a tap processing machine.

[0002]

2. Description of the Related Art Conventionally, drilling using NC control. The tapping machine calculates the movement position data for drilling and tapping based on the machining drawings, etc., and makes a hole and taps with a program that writes numerical data corresponding to the movement position data.

[0003]

Drilling using the conventional NC control described above. The tapping machine calculates moving position data for drilling and tapping based on a machining drawing and then programs it as numerical data. Therefore, it is difficult to program when there is no processing drawing but only a schematic layout of the mounting parts. Therefore, in the case where there is no machining drawing and there is only a schematic layout of the mounting parts, or when the parts are to be mounted according to the actual product, in order to perform hole drilling and tapping with NC control, the operator After making a hole in the upper surface of the work in advance and marking the position of tapping, the operator makes a hole. Drilling on the same vertical line of the injured center point by manually moving the moving part equipped with tapping means. It is necessary to register the coordinates as numerical data in the program by visually matching the tip centers of the tapping means and reading the coordinates of the moving position with respect to the visual aim point.

However, in such a teaching method,
Marking center position and drilling. Since there is a gap between the tip of the tapping means and there is a positional shift due to parallax, and the operator may be confused when positioning, numerical value data registered in the program, that is, moving position data. Often the data is inaccurate or the registration time for the program is long. Therefore, drilling using the conventional NC control. Teaching in a tapping machine has a problem that it requires a lot of labor as well as skill of an operator.

Therefore, in the present invention, the center of the drilling and tapping positions on the work and the drilling. By facilitating the positioning operation of the tap machining means with respect to the machining center, even a beginner can easily perform program registration of the movement position data necessary for NC control. This is a technical problem to be solved.

[0006]

The technical means for solving the above-mentioned problems is drilling. Both tapping means are attached to a moving part that can control movement in two orthogonal directions, and holes are drilled. Drilling by moving both tapping means along the work surface of the work so as to store the movement position data with respect to the target work position of the work. In the tapping machine, a light emitting means for projecting beam light in the visible wavelength band onto the working surface of the work is provided in the moving part, and the pin spot projected from the light emitting means is moved from the reference point to the work point. Every time the moving part is moved so as to match the target machining position of
And the stored pin spot movement position data are stored in the pin spot center point and the drilling. Actual tapping by the moving position data corrected based on the eccentric distance from the center point of both tapping means. Teaching to perform tap processing.
