Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic drilling control device for steel plates, and more specifically, the present invention relates to an automatic drilling control device for steel plates. The present invention relates to a device controlled by.

This type of drilling process has problems different from general drilling processes because the workpiece is huge and thick, and it is produced in small quantities with a wide variety of types, and no modification is allowed at the construction site.

Conventionally, this type of drilling method includes a method using a manual machine and a method using a drilling machine equipped with an NC control device.

The method using a manual machine involves producing a full-size sheet-like template, overlapping it with the steel material to be processed, marking it, and punching it, but this method has the drawback of low work efficiency.

On the other hand, the method using a punching machine with an NC control device is to first create an NC tape using a host computer, output the information stored on this NC tape to a printer to create a check list, and then test it on a template. After machining and checking the perforation position, the actual machining operation begins.

However, due to the high-variety, low-volume production, a great deal of effort and expense is spent on creating, inspecting, and testing programs using a host computer.Furthermore, program errors found during inspection of templates must be corrected at the drilling site. It cannot be corrected and is extremely inefficient.

The present invention was invented in view of the above, and allows programs to be easily created, modified, and changed at the drilling site, and is compatible with various drilling patterns required for processing steel structures such as bridges and steel towers. The objective is to provide an automatic drilling control device that can perform

Another object of the present invention is to combine all the drilling operations on steel plates into five basic patterns and store the master program for each basic pattern in the storage device, whereas conventionally NC tapes were created for each workpiece. An object of the present invention is to provide an automatic drilling control device which can create a drilling program by storing numerical values in a master program and simply inputting numerical values from a numeric keypad into the numerical writing field of the master program.

In summary, the automatic steel plate drilling control device of the present invention includes a table that fixes a steel material to be drilled, a servo mechanism that moves a drilling awl to a predetermined position with respect to the table, and a digital control that controls the servo mechanism. a device, an input device for inputting data such as letters, symbols, numbers, etc. to the control device;
a first storage device that stores basic programs for a plurality of types of drilling patterns; a display device that displays a selected one of the basic programs for the plurality of types of drilling patterns to an operator; A display device that displays indicators indicating variable items that the operator should input using the input device in the displayed program and dimensional data input using the input device; and a second storage device for storing a drilling program in which dimensional data is written, and the input device causes one of the basic programs to be displayed on the display device in response to instructions from the input device, and the input device displays one of the basic programs at a predetermined value writing location. A drilling program is created by writing drilling data from the machine, and the servo mechanism is controlled by the drilling program.

The output interface 10 has the same functions as a conventional NC control device, and instructs the X-axis and Y-axis moving servo motors 2 and 3 to move and stop, instructs the drill head 4 to drill and return, and controls the operation. A confirmation signal is fed back to control the progress of the program.

FIG. 3 shows the basic form of a perforation pattern that can be implemented according to the invention.

The first perforation pattern shown in FIG. 3 is one in which a plurality of unit patterns in which perforation positions are arranged generally rectangularly in the X and Y directions are arranged at predetermined intervals.

In the second perforation pattern shown in FIG. 4, the perforation positions are generally arranged in a rectangular manner in the X and Y directions, and the perforation pitch in the X direction is irregular.

In the third perforation pattern shown in FIG. 5, the perforation position has a center line j having a predetermined inclination with respect to the X direction and the Y direction.

−j, which are arranged in a parallelogram as a whole.

In the fourth drilling pattern shown in FIG. 6, the drilling position is a center line j whose inclination angle changes successively with respect to the X direction and the Y direction.

-j4, they are arranged in a trapezoidal shape as a whole.

In the fifth perforation pattern shown in FIG. 7, perforation positions are arranged along orthogonal coordinates ef rotated by a predetermined angle.

Note that in FIGS. 3 to 1, arrows indicate the direction of movement of the aperture, X0jX1t'..., yo, yl.

In addition, in the case of a staggered arrangement as shown in Fig. 8, this is decomposed into a first regular arrangement pattern A on the orthogonal axis and a second regular arrangement pattern B on the orthogonal axis. A drilling program may be created using the first basic program.

That is, first, write the program for array pattern A as [01

When 01BI 102cOJ is created, two drilling programs are executed successively to perform the drilling shown in FIG. 8.

FIG. 9 is a flowchart illustrating the operation of the present invention, that is, the automatic drilling operation, using the first basic pattern as an example.

When the program starts, in step 21, input numerical values are substituted into variable items in the basic program to create a drilling program.

This program procedure is as described above.

According to this drilling program, the following positioning and drilling operations are controlled.

First, in step 22, drilling is performed in the first column and first row.

When the perforation row is an odd numbered row, the drilling progresses downward as shown by the arrow in FIG. 3, and when it is an even numbered row, it progresses upward. Therefore, in step 23, the program branches depending on whether it is an odd or even numbered row. .

When the machining of the (j+1) row is completed, it means that the machining of one unit pattern is completed, and YES is determined in step 24, and the process returns to determination step 23 to proceed to the machining of the next unit pattern.

When all unit patterns have been processed through such repetition, judgment step 25 is YES.
The program proceeds to step i, and in step 26, the aperture is returned to the origin (OtO), and the program ends.

According to the present invention, it is possible to create a drilling program by simply inputting numerical values from the numeric keypad on the operation panel into the numerical writing field of the master program for each basic pattern.
The work efficiency of creating and managing drilling programs has been improved because the operator can immediately check the suitability of the input on the spot and correct any errors immediately.

In addition, since the drilling patterns for steel plates have been grouped into five basic pattern combinations, the work of creating programs is standardized, and since the drilling operators themselves create the programs, they have a strong sense of responsibility, reducing program errors, and The efficiency of creating drilling programs has also been improved.

Furthermore, according to the present invention, the indicators A, B, C, D, etc. indicating the variable items to be inputted next by the operator and the dimensional data just inputted are displayed on one display. The operator only has to pay attention to the display while proceeding with the work, which has the effect of improving work efficiency.
