In the invention, the laser adopts a machine-carried mode, the machine tool body with the composite structure is adopted simultaneously, and structures of a high-performance flying light path cantilever type laser cutter and a large mesa gantry machine-carried cutter are overlapped, thereby realizing perfect combination of large-size panel processing and high-speed processing, and ensuring the processing quality.
Description
Technical field
The present invention relates to a kind of cutting machine that is used for cutting metal sheet material, relate in particular to a kind of large-table numerical control laser cutting machine.
Background technology
Laser cutting is as a kind of novel thermal cutting technology, and it is fast to have cutting speed, the production efficiency height, and the cutting surface quality is good, advantages such as the little and environmental protection in heat affected area.Become one of main sheet metal cutting mode, obtained application more and more widely.Along with the continuous development of high power laser technology, the working ability of laser cutting, efficient and quality are all improved constantly, and the laser cutting application is also widened the cutting processing of cut deal material from the thin plate cutting.The large-table numerical control cutting off machine is as the essential equipment of cut deal material Laser cutting, but the size range of machining sheet is big, can satisfy industries such as boats and ships, automobile, engineering machinery to large scale cut deal material split requirement, market demand is increasing, has market cause widely.
At present, the machine body of domestic big table top laser cutting machine separates with laser instrument, frame for movement adopts planer type structure, be that cutting head is installed on the planer-type truss, rack and pinion drive mechanism by big stroke promotes the motion of planer-type truss, realize the cutting of large size plate, but the mesa dimensions of this structure can only be accomplished 2 * 4 meters usually, the lathe of bigger table top then need adopt gantry machine-carried type structure if desired.
The large-table numerical control laser cutting machine of the planer type structure of prior art mainly has the following disadvantages:
1, because laser instrument separates with machine body, when machine tool travel was big, the light path of laser instrument was long, causes the energy loss in the Laser Transmission process bigger, thereby influences crudy;
2, laser cutting head is fixedly mounted on the truss of gantry, because gantry truss inertia is bigger, can't satisfy the high speed and precision cutting of small size part, has limited the working (machining) efficiency and the partial operation quality of part.
Summary of the invention
Purpose of the present invention in order to solve the problem that above-mentioned prior art exists, provides a kind of large-table numerical control laser cutting machine of new structure exactly.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of large-table numerical control laser cutting machine, comprise the workbench and the lathe support that fuse, be installed in rack and pinion drive mechanism on the lathe support, be erected at gantry truss on the rack and pinion drive mechanism, be installed in the Y-axis ball screw transmission mechanism on the truss of gantry, and laser instrument and laser cutting head; Be characterized in that described laser instrument is installed on the truss of gantry and can moves with gantry truss.
Also comprise cantilever beam and X-axis ball screw transmission mechanism; Described cantilever beam is installed on the Y-axis ball screw transmission mechanism and can moves as Y direction along Y-axis ball screw transmission mechanism, described X-axis ball screw transmission mechanism is installed on the cantilever beam and can moves along Y direction with cantilever beam, and described laser cutting head is installed on the X-axis ball screw transmission mechanism and can moves as X-direction along X-axis ball screw transmission mechanism.
Described rack and pinion drive mechanism is synchronous clearance elimination gear rack gear.
Large-table numerical control laser cutting machine of the present invention is compared with the large-table numerical control laser cutting machine of prior art, has following advantage and characteristics:
1,, eliminated optical path length and changed processing the influence of mesa dimensions because laser instrument has adopted airborne mode, and promptly laser instrument is directly installed on the truss of gantry and moves with gantry truss, makes optical path length constant substantially.
2, owing to adopted the composite construction machine body, be about to cantilever beam, gantry truss, rack and pinion drive mechanism and lathe support and constituted composite construction, high-performance flight light path cantilevered laser cutting machine is superimposed with the frame for movement of big table top gantry machine-carried type cutting machine, realized the requirement of large size plate processing with High-speed machining.
3, since on the truss of gantry " stack " cantilever beam, flight light path motion in the motion of the cantilever beam by light material and the cantilever beam, realized high-speed, high precision processing within the specific limits, avoided because the deficiency that gantry inertia can't carry out high-speed cutting greatly reaches high-speed cutting and the perfect adaptation of cutting on a large scale.
Description of drawings
Fig. 1 is the basic structure schematic diagram of large-table numerical control laser cutting machine of the present invention.
The specific embodiment
Referring to Fig. 1, numerical control laser cutter of the present invention comprises synchronous clearance elimination gear rack gear 1, laser cutting head 2, X-axis ball screw transmission mechanism 3, Y-axis ball screw transmission mechanism 4, gantry truss 5, laser instrument 6, cantilever beam 7, workbench 8 and lathe support 9.Workbench 8 wherein fuses with lathe support 9, clearance elimination gear rack gear 1 is installed on the lathe support 9 synchronously, gantry truss 5 is erected on the synchronous clearance elimination gear rack gear 1, Y-axis ball screw transmission mechanism 4 is installed on gantry truss 5, laser instrument 6 is installed on gantry truss 5, cantilever beam 7 is installed on the Y-axis ball screw transmission mechanism 4, and X-axis ball screw transmission mechanism 3 is installed on the cantilever beam, and laser cutting head 2 is installed on the X-axis ball screw transmission mechanism 3.Cantilever beam 7, gantry truss 5, rack and pinion drive mechanism 1 have constituted composite construction with lathe support 9.
The course of work of the present invention and principle can be described as follows in conjunction with Fig. 1: sheet material to be processed is placed on the workbench 8.By laser instrument 6 is installed on gantry truss 5, can realize that laser instrument 6 and gantry truss 5 are synchronized with the movement, guarantee the stable of laser optical path length.Y-axis ball screw transmission mechanism 4 can promote cantilever beam 7 and move along Y direction.X-axis ball screw transmission mechanism 3 can promote laser cutting head 2 and move in the X-axis direction.Laser focuses on the sheet material to be processed by laser cutting head 2, realizes the high-speed, high precision cutting of sheet material in the certain limit.By rack and pinion drive mechanism 1, gantry truss 5 moves in the X-axis direction in can be on a large scale, realizes the cutting of large size plate.The Y direction motion of cantilever beam 7 among a small circle and the X-direction motion of laser cutting head 2, cooperate the X-direction motion of large-scale gantry truss 5, realize the perfect adaptation of high-speed, high precision laser cutting and large scale laser cutting, effectively guaranteed quality, efficient and the ability of cutting.
