The birth of Waterjets cutting technology ", has started new era of cold conditions cutting technique, enable these cutting processing problems meet sword and
Solution.
It is well known that the cutting means such as laser, gas plasma, jet, due to the effect of energy field gradient, tangent plane is deeper
When（It is more remote away from nozzle）, cutting power is poorer, and the cut surface formed is often not orthogonal to workpiece surface, referred to as cuts oblique
Degree, this is an inherent shortcoming of all above-mentioned cutting means.Although can be with by improving ablation energy or reduction cutting speed
Part reduces cutting gradient, but still exists the problem of can not be completely vertical.
Five axle high-pressure water cutting machines original three direction move along a straight line on the basis of add cutting head gyroaxis and
Beat axle, realizes the control of cutting head posture, and using the gradient model set in systems in advance, by cutting track
Calculate in real time, consider further that and be modified by the material of cut part and thickness, cutting head is constantly adjusted during cutting
Posture so that the workpiece cut out is reached perfectly without gradient state or formation angle cutting.
In hi-precision cutting head attitude-control device, the angle of gyroaxis axis and swinging axle axis is 90 degree, is swung
Axle using being horizontally mounted, such a structure when swinging axle is rotated, high -pressure water cutting head with one of beat of swinging axle, device be difficult and
It is cut generation interference between workpiece.But such a structure is because cutting head is with one of beat of swinging axle, to the beat essence of swinging axle
Degree proposes higher requirement, because some angular errors of swinging axle can all bring the larger position deviation of point of penetration, therefore,
The transmission accuracy for how improving swinging axle is the problem of field saves to be solved.
The content of the invention
It is an object of the invention to provide a kind of swing shaft transmission of hi-precision cutting head attitude-control device, it can
Improve the rotation precision of swinging axle.
The present invention above-mentioned technical purpose technical scheme is that：
It is provided with and watches in a kind of swing shaft transmission of hi-precision cutting head attitude-control device, including casing, the casing
Motor and the swinging axle parallel with the motor shaft of servomotor are taken, the motor shaft and swinging axle are connected by synchronous pulley group；
Swinging axle side wall is provided perpendicular to be provided with angular encoder on the high -pressure water cutting head of swinging axle, the swinging axle,
Angular encoder and the servomotor electrical connection.
Reductor is provided with the motor shaft of the servomotor, the synchronous pulley group includes what is be connected with reductor
Driven pulley on driving pulley, swinging axle and the timing belt being installed on driving pulley and driven pulley.
Tensioning wheel is additionally provided with the outside of the timing belt.
The lower box is provided with the cutter shaft mouthful of inverted U, and it is intraoral that the swinging axle is horizontally placed on cutter shaft, and swings
Axle two ends are connected by bearing and casing, and bearing gland is provided with outside bearing.
The casing Upper vertical is provided with gyroaxis.
In summary, the invention has the advantages that：
In the swing shaft transmission of hi-precision cutting head attitude-control device, swinging axle is driven using servomotor, synchronous
V belt translation, the drive gap of timing belt is eliminated using tensioning wheel, improves transmission stiffness；And high-precision rotation is installed on swinging axle
Turn encoder, realize closed-loop control, it is ensured that the transmission accuracy of swinging axle.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
The present invention provides a kind of swing shaft transmission of hi-precision cutting head attitude-control device, as shown in figure 1, including
Casing 1, its right side is provided with right case lid 4.The upper end of casing 1 is connected with gyroaxis 2 vertically, when gyroaxis 2 is rotated, is connected to back
Casing in rotating shaft 2 can together be rotated with gyroaxis 2.
Upper level in casing 1 positioned at casing 1, which is provided with servomotor 17, the motor shaft of servomotor 17, passes through one
Reductor 3 is connected with synchronous pulley group, and the synchronous pulley group includes the driving pulley 5 being connected with reductor 3, in driving pulley 5
Lower section be connected to be additionally provided with the tensioning wheel 6 for compressing timing belt 8 in a driven pulley 9, casing 1 by timing belt 8.From
Swinging axle 14 is equipped with movable belt pulley 9, the swinging axle 14 is set in parallel in the underface of servomotor 17.
The right-hand member of swinging axle 14 is provided with angular encoder 10 in figure, and it is electrically connected with servomotor 17, realizes closed loop control
System.The cutter shaft mouthful 141 of inverted U is provided with the bottom of casing 1, the both sides of cutter shaft mouthful 141, which are located on casing 1, to be provided with for pacifying
