Description

The crossbeam driving mechanism of long stroke numerical control laser cutter
Technical field
The utility model relates to a kind of laser cutting machine, particularly the crossbeam driving mechanism of laser cutting machine.
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, realizes the compound motion on plane by the servomotor drive cutting head of digital control system control X-axis and Y-axis.During this equipment work, the transmission accuracy of numerical control X, Y-axis has decisive influence to cutting accuracy.
The crossbeam driving mechanism of existing numerical control laser cutter, mainly include frame and motion crossbeam, between frame and the motion crossbeam two kinds of drive mechanisms can be arranged, one is: be mounted with servomotor on the motion crossbeam, the axle head of servomotor is provided with driving gear, frame upper edge X-direction is provided with tooth bar, and described gear and tooth bar are meshed; During its work, servomotor rotates, and drives motion laterally along X-direction displacement certain distance, realizes cutting head moving at X axis.Another kind of structure is: be mounted with servomotor on frame, the axle head of servomotor is connected with the leading screw that is provided with along X axis, and engagement is provided with nut on the leading screw, described nut and motion crossbeam fix, during its work, leading screw rotates, and promotes nut along the leading screw axially-movable.
Generally speaking, numerical control laser cutter X-axis stroke adopts common feed screw nut transmission just can reach requirement during smaller or equal to 3000mm usually, when adopting feed screw nut's transmission, and the transmission accuracy height; And the X-axis stroke reaches 4000mm even when higher, because the flexible increase of leading screw, leading screw rotates at a high speed and will produce strong shake, noise is increased, precision reduces, so in this case, laser cutting machine manufacturing firm all uses first kind of type of belt drive to carry out transmission both at home and abroad, this method promptly adopts the transmission of rack-and-pinion kind of drive place of lead screw nut, though and can slightly reduce speed raising transmission accuracy.
The utility model content
The purpose of this utility model provides a kind of crossbeam driving mechanism of long stroke numerical control laser cutter, and crossbeam is kept under the prerequisite of good transmission accuracy, also can effectively improve movement velocity.
The purpose of this utility model is achieved in that the cutting head driving mechanism of long stroke numerical control laser cutter, comprise frame, the motion crossbeam, leading screw, nut and servomotor, described leading screw is meshed with nut, described servomotor axle head is connected with driving pulley through reduction box, reduction box fixes through Connection Block and motion crossbeam, described leading screw is installed on the frame along X axis immovably, nut is in bearing is installed in bearing block, described bearing block is fixed on the Connection Block, the nut axle head is connected with the driven pulley with the concentric setting of nut, is in transmission connection through synchronous band between driving pulley and the driven pulley.
During the utility model work, servomotor work drives driving pulley and rotates, driving pulley rotates through the driven pulley of band drive synchronously, and driven pulley drives nut and rotates, when nut rotates, the actuation movement crossbeam is realized the motion of cutting head on X-direction along lead screw straight-line; Compare with existing feed screw nut transmission, in the utility model, because leading screw self does not rotate, rotatory inertia significantly reduces, and rotary speed can significantly improve, and leading screw is easy for installation, and its transmission accuracy height when running up, also can keep than low noise.This device is particularly suitable for being applied to the X axis stroke greater than on 3000mm even the long stroke numerical control laser cutter more than the 4000mm.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 servomotor, 2 reduction boxes, 3 driving pulleys, 4 are with 5 frames, 6 leading screws, 7 driven pulleys, 8 motion crossbeams, 9 Connection Blocks, 10 bearing blocks, 11 nuts, 12 bearings synchronously.
The specific embodiment
As figure, the cutting head driving mechanism of long stroke numerical control laser cutter, comprise frame 5, motion crossbeam 8, leading screw 6, nut 11 and servomotor 1, leading screw 6 is meshed with nut 11, described servomotor 1 axle head is connected with driving pulley through reduction box 2, reduction box 2 fixes through Connection Block 9 and motion crossbeam 8, described leading screw 6 is installed on the frame 5 immovably along X axis, nut 11 is in bearing 12 is installed in bearing block 10, bearing block 10 is fixed on the Connection Block 9, nut 11 axle heads are connected with the driven pulley 7 with nut 11 concentric settings, between driving pulley 3 and the driven pulley 7 through being with 4 to be in transmission connection synchronously.
During work, servomotor 1 work drives driving pulley 3 and rotates, driving pulley 3 is through being with 4 to drive driven pulley 7 rotations synchronously, and driven pulley 7 drives nuts 11 and rotates, when nut 11 rotates, actuation movement crossbeam 8 is realized the motion of cutting head on X-direction along leading screw 6 rectilinear motions; During work, leading screw 6 self does not rotate, and rotation is used to low, and rotary speed can significantly improve, and its transmission accuracy height when running up, also can keep than low noise, can be used on the long stroke numerical control laser cutter of X axis stroke greater than 4000mm.
