Abstract
The utility model provides a moving beam type dual-driving gantry engraving and milling machine, wherein a working platform is arranged on the machine body, a left and a right upright posts are respectively arranged on both sides of the machine body, crossbeams which move along the Y-axis direction are arranged on the left and the right upright posts and are synchronously driven by two motors which are arranged on both ends of the upright posts, a slide plate which feeds along the Z-axis is arranged on a connecting plate, a nc unit is respectively connected with each part, a ballscrew pair is respectively arranged on both sides of the crossbeams, and two leading-screw pairs are respectively connected with two servo motors through two diaphragm flexible couplings. With the structure, the machining accuracy can be improved, the surface roughness can be reduced by half, and furthermore, the acceleration of the machine also can be improved by twenty percent.
Description
Technical field
The utility model relates to a kind of carving and mills machine, and the two gantry carvings that drive of particularly a kind of movable beam type mill machine.
Background technology
When adopt a motor by driving-chain with motion assignment during to the scheme of the axle that is synchronized with the movement, though can realize driven in synchronism, have that driving-chain is grown, transmission mechanism is complicated, gap error is big and can't compensate, and problem such as difficult in maintenance.
The utility model content
The utility model provides the two gantry carvings that drive of a kind of movable beam type to mill machine, it comprises lathe bed, workbench, left and right pillar, crossbeam, connecting plate, slide plate and numerical control unit, workbench are located on the lathe bed, and left and right pillar is located at the both sides of lathe bed respectively, the crossbeam moving along y-axis shift is located on the left and right pillar, and drive by two motor synchronous at column two ends, being located on the connecting plate along the slide plate of Z axle feeding, numerical control unit is connected respectively with each parts, it is characterized in that: a ball screw guide rail respectively is equipped with in the both sides of described crossbeam, and two screw mandrel guide rails are connected with two servomotors by two diaphragm yielding couplings respectively.
Described servomotor is formed driving shaft servo motion control loop with two position feedback devices and CNC position control unit and is connected, and repeatedly kicks into computer.
The advantage of above structure is: 1, adopt the both sides of two motor synchronous controlled motion mechanisms, can solve when driving crossbeam and inertia occurs, influence the problem of machining accuracy; 2, adopt the moving pair servomotors that adopt of y-axis shift to add the ball screw driving, belong to the control of semiclosed loop form, can reach degree of precision; 3, this structure is by the mode that the center of gravity drive principle adopts the mariages thick stick to drive, and greatly improved the vibration resistance of three on lathe, and vibration can reduce nearly 10 times, has improved the lathe dynamic property; 4, owing to adopt mariages thick stick center of gravity to drive, portal frame and moving members such as main shaft center of gravity when high-speed mobile is consistent with the center of driving force, improved and driven stability, reduced the crooked of gantry when mobile, improved contour machining precision, surface roughness can reduce half, and the acceleration of machine spindle also can improve 20% in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, workbench 1 is located on the lathe bed 2, left and right pillar 3,4 is located at the both sides of lathe bed 2 respectively, the crossbeam 5 moving along y-axis shift is located on the left and right pillar 3,4, the both sides of crossbeam 5 respectively are equipped with 10,11, two screw mandrels of ball screw guide rail and are connected with two servomotors 6,7 at column 3,4 two ends by two diaphragm yielding couplings 12,13 respectively.And by two motor 6,7 driven in synchronism, be located on the connecting plate 9 along the slide plate 8 of Z axle feeding.
Mill the two drivings of machine synchronously for gantry foundation formula carving, with the feed shaft of two equidirectional motions, one is set at driving shaft 14, and another is set at driven shaft 15.Form driving shaft servo motion control loop by a servo-driver 16, servomotor 6, position feedback device 17 and CNC position control unit 18, form driven shaft servo motion control loop by another servo-driver 19, another servomotor 7, another position feedback device 20 and CNC position control unit 18 simultaneously.The position control unit 18 of CNC sends the position servo movement instruction to the servo control loop of driving shaft 14 and driven shaft 15 simultaneously.The feedback signal of two position feedback devices 17,20 is relatively encircled except the servo-driver of sending back to separately, a digital comparator also sending into CNC inside carries out difference relatively, this difference is sent into the input of driven shaft servo control loop, and the position servo instruction of sending with CNC position control unit 18 compares.The feedback signal difference of two position feedback devices 17,20 is exactly the synchronous error of driving shaft 14 and driven shaft 15, when difference is zero, shows that the position of two axles is synchronous fully, thereby realizes driven in synchronism.
