Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic punching device capable of punching a plurality of holes at a time in an automatic punching device for punching a hole at a predetermined position of a steel plate and improving work efficiency.

[0002]

[Prior art]

 For example, as a device for making a large number of holes in a workpiece such as a large steel plate, a girder that can travel in the X direction is provided with a spindle head equipped with a tool such as a drill that can be moved in the Y and vertical directions. A known automatic punching device is known. For example, in the automatic punching device 10 shown in FIG. 5, a pair of rails 16 and 16 are laid in parallel along the X direction on both floor surfaces sandwiching the table 14 on which the workpiece 12 is placed. A perforator 18 is movably arranged between the rails 16 and 16. The punching machine 18 includes a carriage 20 which is movably mounted on each rail 16 and a girder 22 which is installed between the carriages 20 and 20 in parallel with the Y direction. Further, a saddle 24 is provided on the girder 22 so as to move in the Y direction along the girder 22, and a spindle head 26 having a drill (not shown) mounted on the saddle 24 is vertically movable. There is.

That is, when punching a predetermined position (position set by XY coordinates) of the workpiece 12 placed on the table 14, first, the carriages 20 and 20 are moved along the rails 16 and 16. Then, the spindle head 26 arranged on the girder 22 is positioned in the X direction. Then, the saddle 24 is moved in the Y direction along the girder 22 to position the spindle head 26 in the Y direction. After the positioning is completed, the spindle head 26 is lowered along the saddle 24, so that the drill mounted on the spindle head 26 drills holes in the workpiece 12 at predetermined positions.

[0004]

[Problems to be solved by the device]

 In the automatic punching device 10, the spindle head 26 disposed on the girder 22 is positioned in the X-Y direction and punched at each drilling position of the workpiece 12. Therefore, if there are many drilling positions of the workpiece 12 and the drilling positions are separated in the Y direction, the spindle head 26 is moved along the girder 22 and positioned at each drilling position. There is a drawback that it takes time and the work efficiency cannot be improved. Further, if the plurality of drilling positions on the workpiece 12 are aligned along the Y direction, the saddle 24 alone is moved while the girder 22 is stopped to move the drilling positions to the drilling positions of the row. The spindle head 26 can be positioned. However, when the work piece 12 is placed on the table 14, the work piece 12 is placed in a state in which the work piece 12 is tilted in a plane with respect to the XY direction in the punching apparatus 10, as shown in FIG. It is almost always placed. Therefore, the drilling position of the work piece 12 is not aligned in the Y direction and is displaced in the X direction, and the girder 22 and the saddle 24 are moved each time the drilling position is drilled to move in the XY direction. It was necessary to carry out positioning, which also caused a decrease in work efficiency.

Therefore, it is conceivable to dispose two punching machines 18 on the rails 16 and 16 so that they can travel freely and to punch two drilling positions on the workpiece 12 simultaneously by both punching machines 18. .. However, in this case, there is a problem that the cost of the automatic punching device itself is almost doubled and becomes extremely expensive. Moreover, it is pointed out that the installation space is increased and that the two punches 18 can be applied only to the large workpiece 12 in which the two punches 18 do not interfere with each other.

[0006]

[Operation of the embodiment]

 Next, the operation of the automatic punching device according to the present invention will be described. As shown in FIG. 4 (a), the work piece 12 is placed in a state in which it is inclined in a plane with respect to the table 14, and the respective drilling positions of the work piece 12 aligned in the Y direction are set. It is supposed to be displaced in the X direction. Then, a case where, for example, points A and B of the workpiece 12 are punched will be described.

First, as shown in FIG. 4A, the girder 22 separated from the workpiece 12 is moved in the X direction by moving the carriages 20 and 20 along the rails 16 and 16. Then, when the first spindle head 36 of the first processing machine 30 moves to a position facing a line parallel to the Y direction passing through the X coordinate at point A, the girder 22 is stopped to perform positioning in the X direction. ..

Next, when the first saddle 33 is moved in the Y direction along the girder 22, when the first spindle head 36 reaches the position where it passes through the Y coordinate at the point A and is on a line parallel to the X direction. By stopping, the first spindle head 36 is positioned immediately above the point A as shown in FIG. 4 (b). In this state, by lowering the first spindle head 36 along the first saddle 33, a drill attached to the spindle head 36 drills a point A of the workpiece 12.

Further, the second saddle 42 is moved in the Y direction along the girder 22, and stopped when the second spindle head 52 arrives at a position facing the line parallel to the X direction through the Y coordinate at the point B. To do. At this time, since the points A and B are displaced in the X direction, the second spindle head 52 does not face directly above the point B. Therefore, the sub saddle 48 is moved in the X direction along the guide rails 46, 46 of the arm portion 44, and the second spindle head 52 arranged on the sub saddle 48 arrives just above the point B. To stop. Next, the second spindle head 52 is moved down along the auxiliary saddle 48, so that the drill mounted on the spindle head 52 perforates the point B of the workpiece 12. As a result, the first spindle head 36 and the second spindle head 52 can be simultaneously drilled at the two drilling positions of the workpiece 12 that are offset in the X direction.

However, the range of misalignment in the X direction that can be simultaneously punched by the first processing machine 30 and the second processing machine 32 is set by the movement amount of the sub saddle 48. Further, the girder 22, the first processing machine 30, and the second processing machine 32 perform the work most efficiently based on the data of the respective drilling positions of the workpiece 12 point-searched by the television camera. The operation is controlled according to the order in which it can be performed.

In the embodiment, the case where a large work piece is perforated has been described, but the present application is not limited to this. For example, a plurality of work pieces are placed on a table and each work piece is processed. The object may be drilled at the first spindle head and the second spindle head. Further, the girder may be provided with three or more processing machines.

[0021]

[Effect of the device]

 As described above, according to the automatic punching device of the present invention, at least two spindle heads are arranged on the girder so as to be movable in the Y direction, so that at least two points of the workpiece can be punched simultaneously. You can Further, since one spindle head is independently movable in the X direction as well, even if the drilling position of the workpiece is shifted in the X direction, it is possible to drill at both positions at the same time. The work efficiency can be improved. Further, since the plurality of spindle heads are arranged on the common girder, the installation space may be the same as the conventional one, but it has an advantage that it can be provided at a low cost while suppressing a large increase in manufacturing cost.
