Description

  In the present invention, when a work plate is placed on a table and the work plate is processed, the work plate is fixed by a plurality of rollers mounted in the vicinity of the spindle head, and the spindle head is interposed between the plurality of rollers. It is related with the processing apparatus of the processed board which inserted the tool of and processed the processed board.

Conventionally, as an NC router processing apparatus, as shown in FIGS. 3 and 4, a lateral support member 3 is laterally mounted on an upper portion of a support 2 that is vertically mounted on a base 1. A bearing (not shown) of a lateral movement member 5 is engaged with the provided rail 4, and a screw shaft 7 connected to a servo motor 6 attached to an end of the lateral support member 3 is attached to the lateral movement member 5. The horizontal movement member 5 is positioned and moved in the horizontal direction by being driven by the servo motor 6 by being fitted with the boss (not shown), and the vertical movement member 9 is mounted on the rail 8 vertically mounted on the horizontal movement member 5. Bosses (not shown) mounted on the longitudinally moving member 9 on a screw shaft (not shown) connected to a servo motor 10 mounted on the top of the laterally moving member 5. ) Are engaged, and the longitudinally moving member 9 is driven by the servo motor 10. The spindle head 11 is mounted on the longitudinally moving member 9, the spindle 12 mounted on the spindle head 11 protrudes downward, and a tool 13 is attached to the lower part of the spindle 12 by a collet nut. A rail 15 is mounted on the upper part of the base 14 orthogonal to the base 1, and a bearing 16 is engaged with the rail 15. The bearing 16 is attached to the lower part of the table 17, and is attached to the end of the base 14. A boss (not shown) attached to the lower portion of the table 17 is engaged with a screw shaft (not shown) connected to the mounted servo motor 18, and the servo motor 18 is driven to drive the table 17 to the spindle head. 11 has been proposed that is positioned and moved back and forth.

  However, in such a processing apparatus, a large number of air holes are opened in the table 17 to suck air and suck the work plate 19, and the work plate portion 19 positioned on the table 17 is attached to the spindle head 11. When the processed plate 19 is thickened, there is a problem that the processed plate 19 positioned by sucking air is slightly displaced by the tool 13 when processed.

  The problem to be solved is that in a conventional processing apparatus for a processed plate, when the processed plate becomes thick, the processed plate positioned by sucking air is slightly displaced by the tool when processing. there were.

The invention, and the spindle head to be moved along the transverse support member mounted on the top of the column, which is configured to move the horizontal support member and Cartesian the base table on the table, the neighborhood of the strut A plurality of opposed cylinders mounted on both side surfaces of the base table, rollers mounted on the drive shafts of the plurality of cylinders in parallel with the moving direction of the table, and the spindle head A machining control device that outputs the position of the table positioned in accordance with the machining position of the workpiece to be machined, a memory that stores a table position signal from the machining control device, and a memory that is stored in the memory a reading function of reading a position signal, the position signal read by the reading function, by which the table approaches, the Te of the plurality of cylinders And a cylinder control device comprising a drive signal output function of outputting a driving signal for sequentially up or down the cylinder close to the table, by the sequential up or down a plurality of cylinders, the plurality of cylinders The rollers mounted on the drive shaft are sequentially raised or lowered to press the work plate on the table .

In the processing apparatus for processing a plate according to the present invention, when the table on which the processing plate is placed moves to the vicinity of the spindle head, the opposite ends of the roller are driven to a pair of opposed cylinders fixed to the drive shaft. By pressing the work plate with a roller mounted on the drive shaft of the cylinder, the position of the work plate is not displaced when machining the work plate with the tool of the spindle head lowered between the rollers. There is an advantage that the work plate positioned in the position can be processed.

In the present invention, the work plate is placed on a table that conveys the work plate, and the rollers are respectively attached to the drive shafts of the cylinders facing each other of the plurality of cylinders that are respectively attached to the side surfaces of the base table in the vicinity of the spindle roller. When processing the placed work plate, the opposed plate is driven and the work plate is positioned and fixed by the roller, so that the work plate is processed without any deviation.

FIG. 1 is a side view of an apparatus for processing a processed plate according to an embodiment of the present invention. Reference numeral 2 denotes a support, 3 denotes a lateral support member, 5 denotes a lateral movement member, 9 denotes a longitudinal movement member, 11 denotes a spindle head, and 14 denotes a base. The table 17 is a table, and the configuration thereof is the same as the above-described conventional example, and the description thereof will be omitted. In this embodiment, a work plate 19 is placed on the table 17 and the base table 14 in the vicinity of the column 2 is installed. Four pairs of cylinders 20a, 20b, and 20c20d are mounted on the opposite side surfaces, and rollers 21a, 21b, and 21c21d are parallel to the traveling direction of the table 14 on the drive shafts of the cylinders 20a to 20d. across in mounted, the tool spindle head 11 between the rollers 21c of the roller 21b and the cylinder 20c of the cylinder 20b is configured to be positioned.

  Further, as shown in FIG. 2, a positioning signal of the table 17 positioned at the time of machining from the machining control device 22 is stored in the memory 23, and a reading function 24a for reading the positioning signal of the table 17 from the memory 23, and this reading function A drive signal output function 24b for creating cylinder drive signals for driving the cylinders 20a to 20d from the positioning signals of the table 17 read by the table 24a is built in the cylinder controller 24.

  In the processing apparatus for the processed plate of this embodiment configured as described above, when the table 17 on which the processed plate 19 is placed is moved in the vicinity of the roller 20 a close to the table 17, it is stored in the memory 23. The cylinder control device 24 detects the position of the table 17 based on the positioning signal of the table 17 from the processing control device 22, and drives the cylinder 21a just before the table 17 approaches the roller 20a to sequentially raise the rollers 21a to 21d. The cylinders 20a to 20d are driven so as to descend.

  In the workpiece processing apparatus of the present embodiment configured as described above, when the table 17 approaches the processing position of the table 17 at the time of processing, the cylinders 20a to 20d are sequentially moved from the processing signal output from the processing control device 22. By driving, the rollers 21 a to 21 d do not collide with the work plate 19 placed on the table 17, so that the work plate 19 is not displaced and is accurately positioned by the tool of the spindle head 11. The work plate 19 can be processed.

In the above embodiment, four cylinders 20a to 20d and four rollers 21a to 21d are used to press the work plate 19 on the table 17, but four cylinders and four rollers are used. The above may be provided, or may be four or less . Further, the rollers 17a to 21d are used, and the table 17 opens a large number of air holes, and sucks air to attach the work plate 19 to the table 17. You may make it position by adsorb | sucking.
