を自動的に穿孔する装置に関する。[Detailed Description of the Invention] <Technical Field> The present invention relates to an apparatus for automatically drilling holes in a predetermined pattern at predetermined locations at both ends and in the middle of a long section steel such as an H-section steel or a channel steel. Regarding.
＜従来技術＞
従来、この種装置の穿孔位置決め方式には、大

う方式である。<Prior Art> Conventionally, there are two types of methods for positioning holes in this type of device: The first method is
Multi-axis drilling heads are installed on the right, left, and upper sides of the fixed portal frame, and the pitch of the holes in the transverse direction of the section steel is set in advance during setup.
In the longitudinal direction, the entire shaped steel is moved by a conveyor according to its pitch.The second method is to manually transport the shaped steel into the machine, fix it in a vise, and move it with a freely sliding cross. This is a method for positioning by moving a drilling head mounted on a slide device.

作業を行うことはできなかつた。 In the first method of the former, it is possible to position almost the entire length of a long section steel in the longitudinal direction, but on the other hand, the section steel itself is moved back and forth for positioning, so the section steel to be machined is especially H-section steel. In the case of various lengths, such as those shown in FIG. the second of the latter
With this method, highly accurate positioning is always possible regardless of the size or length of the shaped steel. In particular, when drilling holes in H-beam steel, a group of holes in a predetermined pattern P are drilled at several locations in the longitudinal direction, as shown in Figure 1, instead of continuously drilling a large number of holes over the entire longitudinal direction. This second method is suitable for positioning within a group of holes in a predetermined pattern since it involves most of the work. However, since the holes in the predetermined pattern are generally quite far apart, in the second method, the shaped steel must be moved manually or by conveyor during this time. It was not possible to perform drilling work.

を目的とする。<Object of the invention> The present invention has been made in view of the above, and when drilling holes at both ends and at predetermined locations in the middle of a long shaped steel, the shaped steel is fixed and the drill is sequentially moved according to a program. By drilling in parallel, the machining of one hole group pattern can be maintained with high precision, and the movement from the already machined hole group to the position of the next hole group to be machined transports the section steel at high speed. The purpose of this invention is to provide an automatic drilling device for shaped steel that maintains the distance between hole groups with high precision.

ことになる。 First, the workpiece W is set at a predetermined position on the vice table 2, and when a start command is given, the vice 3a,
3b clamps and fixes the workpiece W, and vises 3a, 3
From b, a clamping signal for the workpiece W is input to the control section 21, and confirmation of clamping of the workpiece W is performed. Then the first, second and third drilling heads 6a,
6b and 6c independently perform drilling based on the respective drilling position coordinates written in the storage device 22, and issue a drilling completion signal when all drilling is completed. When the drilling completion signals from all drilling heads have been input, vices 3a and 3
b is warmed, and while the workpiece W has not reached the placement position of the photo switch 10, the workpiece W is moved by the front transport device 8, and after reaching the rear transport device 8', the workpiece W is moved to the preset position. Convey based on the conveyance target value. At this time, the inertia changes depending on the size of the material, resulting in excess or deficiency in the amount of conveyance, but the amount of conveyance is actually measured by the measuring device 9 or 9'.
The control unit 21 calculates the difference ε between the conveyance target value and the actual conveyance value. Then, the origin of the drilling coordinates in the drilling program for each drilling head is corrected by the calculated difference ε, and the vice
After tightening the holes 3a and 3b to clamp the workpiece W, drilling is performed by each of the drilling heads 6a, 6b and 6c. As a result, as shown in FIG. 7, the distance between the first hole group P 1 (coordinate origin S 1 ) and the second hole group P 2 (coordinate origin S 2 ) to be drilled is L. At some point, if the conveyance amount by the conveyance device 8 or 8' becomes L', the coordinate origin must be corrected.
Drilling is performed with S 2 ' as the origin, and an error occurs in the interval between the hole groups by ε. However, since this ε is calculated and the coordinate origin in the drilling program is corrected by that amount, the second hole group P 2 In this case, accurate drilling is performed at the regular origin S2 despite the error in the conveyance amount.

Since the coordinate origin of the coordinates is corrected, the pattern within the hole group is maintained with high precision, and the distance between the hole groups is maintained at high speed while the pattern is maintained with high accuracy. Maintains high accuracy.

である。 In addition, the conveyance device is composed of a combination of a drive roller that conveys the shaped steel while holding the left and right sides of the shaped steel, and an idle roller that can come into contact with the left and right sides of the shaped steel, so a balanced force acts on the shaped steel on both sides, ensuring smooth operation from start to finish. The measurement accuracy of the measuring device is extremely high.
By the way, in bridges and steel tower buildings, even though the distance between the steel groups at both ends of the long shaped steel is as long as 15 meters, a dimensional error of 1 to 2 mm is required, and the accuracy is 1/15000 to 1. /7500, which is extremely high precision, so high-precision measurement of the conveyance amount is important.

It is simple and has low manufacturing cost. In addition, since it has two sets of vice mechanisms and two sets of conveyance devices before and after the drilling head, the workpiece is conveyed in one direction from the tip hole group to the rear end hole group of the long section steel. All machining is completed just by doing this, and automatic continuous machining of many long steel sections becomes possible.

項記載の形鋼の自動穿孔装置。[Scope of Claims] 1. A device for drilling a group of holes in a predetermined pattern at a plurality of predetermined positions in the longitudinal direction of a long shaped steel, comprising a memory in which information on the predetermined pattern is written as drilling position coordinates based on a coordinate origin. A device, a drilling device that controls the drilling head within a predetermined area according to data in the storage device, a vice mechanism that is installed before and after the drilling device in the longitudinal direction of the shaped steel to clamp and fix the shaped steel, and a shape of the vice mechanism. Front and rear conveyors are installed at the front and rear in the longitudinal direction of the steel, and transport the shaped steel by a preset target value while holding both the left and right sides of the shaped steel between drive rollers and idler rollers that can be moved apart and in contact with each other. means, a movement measuring device disposed near the drive roller to continuously measure the longitudinal movement of the shaped steel, and automatically calculating the difference between the actual measurement value of the movement measuring device and the target value. and a conveyance error correction means for correcting the coordinate origin of the next group of holes to be drilled by the difference. 2. Claim 1, which is equipped with punching devices that are driven and controlled independently from each other at three locations: on the left side, on the right side, and above with respect to the conveyance direction of the long section steel.
Automatic drilling device for section steel as described in Section 1.
