Description
Technical field
The present invention relates to a kind of numerical control laser cutter, particularly a kind of main machine structure of numerical control laser cutter.
Background technology
Numerical control laser cutter is that laser is carried out part processing as a kind of manufacturing process to metal and nonmetal plate, servomotor by digital control system control X-axis and Y-axis drives cutting head and realizes the compound motion on plane, can be on flat sheet the curve of processing linear and arbitrary shape.This equipment is a kind of sheet material cutting equipment of efficient, high automation, and it is widely used in textile machine, machine-building, automobile, meter switch, household electrical appliances manufacturing, lift facility manufacturing, food industry, decoration and advertisement etc.
At present, two kinds of numerical control laser cutter agent structures are arranged:
A kind of is bilateral driving gantry beam portable structure, comprises fuselage, and both sides are the upright bracing frame that is provided with before and after the fuselage, and two bracing frame upsides are provided with the guide rail that is parallel to each other; Two bracing frames are provided with mobile gantry fine strain of millet, beam two ends, gantry are respectively equipped with the slide block that matches and install with guide rail, also be provided with the rack-and-pinion driving mechanism between gantry beam and the respective support frame, the cutting head that can move along gantry beam length direction is installed on the beam of gantry, links to each other through light path between laser instrument and the cutting head.During its work, laser instrument sends laser and shines on the plate to be cut through cutting head, the rack-and-pinion driving mechanism can drive gantry beam along guide rail direction shift position, corresponding cutting head is along X-motion, when cutting head moves along gantry beam length direction, also be cutting head along Y-axis to moving, like this, cutting head is realized the axial compound motion of X-Y, plate can be cut into required form.Its weak point is: because gantry beam weight is big, influenced the lifting of movement velocity; The pinion and rack of both sides drives and has asynchronous problem, can make gantry beam produce asynchronous distortion, has reduced cutting accuracy, and its man-machine proximity is relatively poor in addition.
Another kind is monolateral driving cantilever beam portable structure, comprise that fuselage, cantilever beam, cutting are first-class, cantilever beam one end uses the guide rail slide block that guiding is installed on fuselage, the other end is unsettled, the cantilever beam support end is realized moving along fuselage length direction (X-axis) by the feed screw nut transmission mechanism, being equipped with on cantilever beam can be along the mobile cutting head of cantilever beam length direction (Y-axis), links to each other through light path between laser instrument and the cutting head.This structure weak point is: because cantilever beam one end supports, the other end is unsettled, and the feed screw nut transmission mechanism is monolateral driving, so transmission rigidity is relatively poor, easily produces shake at a high speed, influences transmission accuracy and cut quality.
In addition, the laser instrument of existing laser cutting machine and fuselage are the designs of two bodies, and its Laser Transmission stability is not enough.
Summary of the invention
The main machine structure that the purpose of this invention is to provide a kind of numerical control laser cutter makes the integral rigidity of lathe good, and the good stability of lathe is easy to realize high speed.
The object of the present invention is achieved like this: the main machine structure of numerical control laser cutter, comprise fuselage, laser instrument, Long Menliang, moving beam and cutting head, and both sides are the upright bracing frame that is provided with before and after the fuselage, Long Menliang is arranged between the two bracing frame upsides; When laser instrument sends laser, give cutting head with laser transfer, fixedly connected with the respective support frame respectively in beam two ends, described gantry, beam downside suspention in gantry has the moving beam that can move along gantry beam length direction, described moving beam and Long Menliang are spatial vertical and arrange, the suspention of moving beam downside has the cutting head that can move along the moving beam length direction.
This device is fixedlyed connected gantry beam with bracing frame, make fuselage form stable ring seal structure, strengthened the rigidity of lathe, improved the stability of lathe, when cutting head moves along the moving beam length direction, can realize the Y-motion of cutting head, when moving beam moved along gantry beam length direction, cutting head can realize that X axis moves, like this, move in X-Y plane by the control cutting head, plate can be cut into required form.Between gantry beam and the moving beam, all can adopt transmission mechanisms such as feed screw nut's driving very perfect in the prior art, rack-and-pinion driving between moving beam and the cutting head, make it to realize that straight line moves.Compared with prior art, the present invention is simple in structure, has reduced the whole inertia of moving-member, makes cutting head can realize high-speed mobile, improves cutting speed; Can use the middle part to drive, activation point is better, has improved cutting accuracy; In addition, this structure has strengthened the stability and the intensity of fuselage, and the present invention can be used for the digital control laser cutting.
Stable for guaranteeing the laser instrument bright dipping, described laser instrument is fixedly mounted on the bracing frame of fuselage one end.In the course of the work, can not cause skew because of vibration.
