Description

  In the present invention, screw shafts are attached to both sides of the table base, bosses are respectively engaged with these screw shafts, one end of the mounting member is fixed to these bosses, and the other end is fixed to the table. The present invention relates to a processing apparatus for a plate to be processed in which the table can be moved without being tilted by driving the table with a screw shaft.

  Conventionally, as shown in FIGS. 4, 5, and 6, as a processing apparatus for a plate to be processed, a lateral support member 3 is mounted on the upper side of a support column 2 that is mounted vertically on a base base 1. A bearing (not shown) of a lateral movement member 5 is engaged with a rail 4 provided on the front surface of the support member 3, and a screw shaft 7 connected to a servo motor 6 attached to an end of the lateral support member 3 is provided. A rail which is fitted to a boss (not shown) mounted on the laterally moving member 5 and is positioned and moved in the lateral direction by driving of the servo motor 6, and which is vertically mounted on the laterally moving member 5. 8 is engaged with a bearing (not shown) of the longitudinally moving member 9, and is attached to the longitudinally moving member 9 on a screw shaft (not shown) connected to a servo motor 10 attached to the upper part of the laterally moving member 5. The boss (not shown) is engaged and driven by the servo motor 10 The moving member 9 is moved up and down, a spindle head 11 is attached to the longitudinally moving member 9, and a spindle (spindle) 12 attached to the spindle head 11 protrudes downward. 13 is mounted, and a rail 15 is mounted on the upper portion of the table base 14 orthogonal to the base table 1. A bearing 16 is engaged with the rail 15, and the bearing 16 is mounted on the lower portion of the table 17. A boss (not shown) attached to the lower portion of the table 17 is engaged with a screw shaft (not shown) connected to the servo motor 18 mounted on the end of the drive motor 14 to drive the servo motor 18. It has been proposed that the table 17 be positioned and moved back and forth with respect to the spindle head 11.

However, in the processing apparatus for a processed plate configured as described above, a boss is engaged with one screw shaft connected to the servo motor 18 at the lower portion of the table 17, and an attachment member is provided between the boss and the table. Since the table 17 is moved by mounting, the backlash between the screw shaft and the boss, the backlash between the rail and the bearing (block), the backlash of the table 17 occurs, There is a problem that the position of the table 17 is slightly shifted when the processed plate is processed, and the longitudinally moving member 9 is configured to be moved up and down by one servo motor 10, so that a large number of spindle heads 11 are mounted. In this case, there is a problem that the spindle head 11 is slightly inclined due to the backlash between the screw shaft and the boss due to the backlash between the rail and the bearing (block).
Japanese Patent Application No. 2003-113701

  The problem to be solved is that in the conventional processing apparatus for processing a plate, since the table is positioned by one screw shaft and one boss, the position of the table is slightly shifted. In addition, when a plurality of spindle heads are mounted on the longitudinally moving member, there is a problem that it is slightly inclined due to backlash between the screw shaft and the boss.

  In the present invention, parallel rails are mounted on an upper portion of a table base mounted on a base table, and the first table is mounted with bearings engaged with the parallel rails on the lower surface, and the first and second screw shafts. Are mounted on the side surfaces of the first table base, the first and second servo motors drive the first and second screw shafts, respectively, and the bosses engage with the first and second screw shafts, respectively. The mounting member has one end connected to the boss, the other end fixed to the lower part of the table, and the beam sandwiching the table base on the upper part of the support base mounted on the base base on both sides of the table base, Mounted in a direction orthogonal to the moving direction of the table, the laterally moving member is mounted with a bearing that is engaged with a rail mounted along the beam, and a laterally moving servo motor mounted on the beam is mounted on the beam, Dress Vertical moving member that is configured to move in the vertical direction of the lateral movement member, vertical movement servo motor mounted to the lateral movement member is a vertical movement member which is configured to be driven.

  In the processing apparatus for a processed plate according to the present invention, the table on which the processed plate is placed is connected to the boss engaged with the screw shaft mounted on both sides of the table base by the mounting member, and the two screw shafts are connected to each other. By driving each servo motor synchronously, the left and right sides of the table are not tilted or displaced, it moves smoothly, the position of the work plate does not shift, and the work is positioned securely. There is an advantage that the plate can be processed.

  In the present invention, in order to smoothly move the table carrying the workpiece plate without tilting left and right, screw shafts are mounted on both sides of the table base, and the two screw shafts are synchronously rotated by two servo motors. By connecting the boss engaged with the shaft to the table with an attachment member, the processed plate is processed without any displacement.

Is a support column, 3 is a lateral support member, 4 is a rail, 5 is a lateral movement member, 9 is a longitudinal movement member, 10 is a servo motor, 11 is a spindle head, 14 is a table base, 15 is a rail, 16 is a bearing, 17 is The table 18 is a servo motor, and the configuration thereof is the same as that of the above-described conventional example, and the description thereof is omitted. In this embodiment, the longitudinally moving member 9 is equipped with four spindle heads 11a, 11b, 11c, 11d, and The vertical movement member 9 is moved up and down by two servo motors 10a and 10b. Further, two table bases 14a and 14b are attached to the lower part of the horizontal support member 3, and 2 on each side of the table bases 14a and 14b. Two screw shafts 20a and 20b The boss 21 is engaged with each of the two screw shafts 20a and 20b, and the other end of the mounting member 22 with one end fixed to the boss is fixed to the tables 17a and 17b. Each of the shafts 20a and 20b is provided with one servomotor mounted on one screw shaft, and each screw shaft 20a and 20b is configured to be driven by the servomotors 18a and 18b, respectively.

  In the processing apparatus for the processed plate of this embodiment configured as described above, the screw shafts 20a and 20b are mounted on both sides of the table bases 14a and 14b, respectively. The mounting members 23 are fixed to the bosses 22 that are driven and engaged with the screw shafts 20a and 20b, respectively, and connected to the tables 17a and 17b, so that the tables 17a and 17b move smoothly without being inclined. Therefore, there is an advantage that the position of the processed plate is not shifted and the processed plate can be reliably processed, and the tables 17a and 17b are moved synchronously. Even with a large processed plate that straddles the two tables 17a and 17b, the position of the processed plate does not shift, There is an advantage that it is possible to process the target plate which is indeed positioned.

  In addition, since the longitudinally moving member 9 is moved up and down by the two servo motors 10a and 10b, the longitudinally moving member 9 does not tilt even if the spindle head 11 is mounted and the weight balance is poor. The vertical movement is performed smoothly, and there is an advantage that the processed plate can be reliably processed by the spindle heads 11a to 11d.

  In the above embodiment, the two tables 17a and 17b are mounted. However, one table may be used, and one servo motor is mounted on one screw shaft, but the screw shafts on both sides of one table are connected to the belt. Alternatively, gears may be used for synchronous driving, and further, an example in which four spindle heads are provided on the longitudinally moving member 9 is shown, but there may be one, two or three. In addition, many spindle heads may be mounted.
