Gantry numerical control machining center and control system and machining method of gantry numerical control machining center

Abstract

The invention discloses a gantry numerical control machining center and a control system and a machining method of the gantry numerical control machining center. The gantry numerical control machiningcenter comprises a worktable device. The worktable device comprises multiple sets of automatic positioning moving worktable mechanisms which are arranged in the X direction. The gantry numerical control machining center has the beneficial effects that automatic moving positioning of worktables and suckers can be achieved. The control system comprises a CNC controller, a servo control unit in parallel connection with a bus in a bidirectional control manner, a machine head control unit, a worktable control unit and a vacuum control unit. The worktable control unit comprises multiple sets of automatic positioning moving worktable control units and X-direction positioning control units. Each set of automatic positioning moving worktable control unit comprises a set of worktable X-axis feedingservo system, multiple sets of sucker Y-axis feeding servo systems and a Y-direction positioning control unit. The worktable X-axis feeding servo systems and the sucker Y-axis feeding servo systems are connected with a bus of a PLC in parallel. The control system has the beneficial effects that universality is achieved, compatibility is high, and transportability is high.

Description

technical field [0001] The invention relates to the field of large-scale precision numerical control machine tools in the field of processing wood and similar boards, in particular to a gantry numerical control machining center with a high-grade numerical control system for processing wood, and its control system and processing method. Background technique [0002] With the emergence of microprocessors, the world has entered a new era of numerical control, and the multi-axis control machine tools that can only be realized by computers have risen rapidly, bringing wood processing into an era of automation and intelligence. field of application is becoming more and more common. [0003] In the prior art, the CNC wood processing center can complete the engraving and milling, vertical drilling, and grooving processes. With the help of the wood processing center, the wood can be processed conveniently and the production efficiency can be improved. However, after the wood is engr...

AI Technical Summary

Problems solved by technology

[0022] In this invention patent, the independently movable vacuum chuck with air lock must have an air lock assembly in order for the vacuum chuck to be positioned at the processing position, and the lock assembly includes an intake piston seat, a piston plate, a piston movable plate, and a wave elastic Washer, two hook plates, two inserts, two insert fixing sleeves, left port block, there are too many parts, the structure is complicated, and the installation is difficult

[0023] The plate adsorption device must include a suction cup loosening mechanism, a moving sliding mechanism, the first air switch and the second air switch, and there are too many parts, the structure is complicated, and the installation is difficult.

[0024] In the above two invention patents, the suction cup cannot be moved automatically, and the suction cup needs to be manually moved to the processing position. The positioning of the suction cup is not accurate, which greatly increases the risk and greatly increases the occurrence of failures

Moreover, if the operator does not operate properly, it is easy to damage the suction cup mechanism, damage the tool, and easily cause safety accidents.
