And the center of the beam 405 is located directly above the machining position. By adopting the layout mode, the large enough drilling operation space can be ensured, the blockage of the iron cutter in a narrow space is avoided, and the enough operation space of the feeding mechanism is also provided.
As shown in fig. 1 to 6, the operation process of the robot assisted intelligent machining center 1 is as follows: the workpiece 10 slides down to the stop mechanism 307 from the upper end of the feeding slide rail 303, and after the stop cylinder 311 drives the stop piston rod 311a to retract, the workpiece 10 continues to slide down and leave the feeding slide rail 303. The feeding cylinder 315 pushes the exiting workpiece 10 into the feeding chute 319 and slides along the feeding chute 319 to the feeding position. Then, the traverse cylinder 407 drives the first cylinder 417 to move laterally to a position close to the feeding position, the first cylinder 417 drives the second cylinder 419 to move vertically to a position close to the feeding position, and the second cylinder 419 drives the feeding claw 421 to clamp the workpiece 10 at the feeding position. Then the first cylinder 417 drives the second cylinder 419 to vertically move away from the feeding position, the traverse cylinder 407 drives the first cylinder traverse 417 to move away from the feeding position and approach the processing position, then the first cylinder 417 drives the second cylinder 419 to vertically move towards the processing position, and then the second cylinder 419 controls the feeding claw 421 to release the workpiece 10 to place the workpiece 10 at the processing position. Then, the traverse cylinder 407 drives the third cylinder 423 to move transversely to a position where the workpiece pressing block 425 is close to the processing position. Next, the third cylinder 423 drives the workpiece pressing block 425 to approach the processing position in the vertical direction, so that the workpiece pressing block 425 presses the workpiece 10 located at the processing position. Next, the drilling device 601 performs drilling on the workpiece 10. After the workpiece 10 at the machining position is drilled, the third cylinder 423 drives the workpiece pressing block 425 to move away from the machining position along the vertical direction, so that the workpiece pressing block 425 loosens the workpiece 10. Then, the traverse cylinder 407 drives the fourth cylinder 427 to move transversely to a position close to the machining position, the fourth cylinder 417 drives the fifth cylinder 429 to move vertically to a position close to the machining position, the fifth cylinder 429 drives the sixth cylinder 431 to move to a position close to the machining position along a direction parallel to the table top and perpendicular to the cross beam 405, and the sixth cylinder 431 drives the material receiving claw 433 to clamp the workpiece 10 located at the machining position. Then fourth cylinder 427 drives fifth cylinder 429 vertical motion and keeps away from the feed position, violently walk cylinder 407 and drive the fourth cylinder and violently 427 keep away from the processing position and be close to the material receiving position, then fourth cylinder 417 drives fifth cylinder 429 vertical motion and is close to the material receiving position, fifth cylinder 429 drives sixth cylinder 431 and moves along the direction that is on a parallel with the mesa and perpendicular to crossbeam 405 and be close to the material receiving position, sixth cylinder 431 drives material receiving claw 433 and loosens work piece 10, places work piece 10 in the material receiving position. The workpiece 10 is then slid along the collector 70 away from the table 203 for storage or further processing. The above is the working principle and the operation process of the mechanical arm assisted intelligent machining center. The workpiece 10 is simply and conveniently fed, drilled and received by adopting the mode. Can improve the operating efficiency greatly, shorten consuming time of drilling process, promote the productivity.
