The specific embodiment
As shown in Figure 1, 2, a kind of segmented mold slide block dedicated numerical control milling machine of the present invention, comprise controller,
Support 1, rotary disk seat 10, Y-axis slide 5, X-axis slide 6 and main spindle box 7.Wherein, Y-axis travel mechanism is arranged on support 1, and rotary disk seat 10 is arranged on support 1 one end, and on rotary disk seat 10, being provided with can be around X-axis upset circular turned dish 3 that can axial rotation, and rotary disk 3 rear portions arrange worm gear case 2.On rotary disk 3, by the shaft seat connecting chuck 13 at center, gyroaxis drives chuck 13 to rotate while rotating, be respectively arranged with the step jaw 11 that can move radially in the quartering direction of chuck 13, and to be processed 4 use claws 11 are fixed.Y-axis slide 5 is arranged on support 1 by Y-axis travel mechanism and is relative with rotary disk seat 10, on Y-axis slide 5, is provided with X axis travel mechanism; X-axis slide 6 is arranged on Y-axis slide 5 by X axis travel mechanism, is provided with Z-axis direction travel mechanism on X-axis slide 6; Main spindle box 7 is arranged on X-axis slide 6 by Z-axis direction travel mechanism, is provided with horizontal mill principal axis 8 on main spindle box 7.X axis travel mechanism, Y-axis travel mechanism, Z-axis direction travel mechanism and rotary disk 3 are all connected with servomotor by transmission mechanism, and servomotor connects controller.Controller carries out four-axle linked control to the gyroaxis of X-axis, Y-axis, Z axis and rotary disk 3, thereby has improved control accuracy.
For can realize rotary disk 3 around 0 ° ~ 90 ° upsets of X-axis, the trip shaft of X axis is set on rotary disk seat 10, rotary disk 3 is connected on trip shaft, trip shaft is connected with upset reducing motor, after starting upset motor 12, upset motor 12 drives trip shaft to rotate, thereby drives rotary disk 3 around X-axis upset, to meet the needs of workpiece processing.In worm gear case 2 sides, arc be set and be with graduated transmission chi dish 9 simultaneously.At rotary disk 3, when overturning, X-axis can read the angle of upset by transmission chi dish 9.In order to realize the axial rotation of rotary disk 3, the interior worm-and-wheel gear that arranges of worm gear case 2, wherein rotary disk 3 is as the worm gear in worm-and-wheel gear, under the driving of servomotor, worm screw is rotated and drives worm gear to rotate, thereby has realized the axial rotation of rotary disk 3.
X axis travel mechanism, Y-axis travel mechanism, Z-axis direction travel mechanism include screw mandrel and are positioned at the slide rail of screw mandrel both sides.Wherein, Y-axis leading screw extended line extends to left side or the right side at rotary disk 3 centers, and namely Y-axis leading screw is eccentric setting.Through measuring and calculating, the extended line of Y-axis leading screw departs from left side or the right side 150-300mm at rotary disk 3 centers.
Add man-hour carrying out segmented mold slide block, first workpiece is placed on the chuck 13 on rotary disk 3, and workpiece is blocked fixing with claw 11.By the startup motor 12 that overturns, adjust the angle that rotary disk 3 tilts, with the milling cutter meeting on mill principal axis 8, carve with workpiece the condition that end face is vertical.Then controller controls that X-axis moves simultaneously, y-axis shift is moving, Z axis moves and the axial rotation of rotary disk 3, thereby realizes the operation that milling cutter is processed at workpiece diverse location.Workpiece is when being turned to vertical state, workpiece bottom position is lower, need main spindle box 7 to drop to lower position and just can complete engraving, but this needs larger space, in order to address this problem, the present invention has adopted the eccentric setting of Y-axis leading screw, so main spindle box 7 does not need to drop to bottom along Z-axis direction travel mechanism, but mill principal axis 8 remains at workpiece left side or position on the upper side, bottom, right side processes, and has greatly saved space.
As shown in Fig. 3,4,5,6, rotary disk 3 is as the worm gear in worm-and-wheel gear, it comprises that center is provided with the fast pulley 3-1 of shaft seat, the wheel face edge of fast pulley 3-1 is provided with annular draw-in groove, in draw-in groove, be provided with annular castor 3-3, castor 3-3 upper surface with on draw-in groove along concordant, the outer circumference surface of fast pulley 3-1 arranges the latter half of a circle worm-gear toothing, the outer circumference surface of castor 3-3 arranges the first half of a circle worm-gear toothing.The outer circumference surface of fast pulley 3-1 and castor 3-3 splices the complete worm-gear toothing of common composition one circle up and down, and castor 3-3 and fast pulley 3-1 top are superimposed with pressing plate 3-2, and pressing plate 3-2 is fixedly connected with fast pulley 3-1.Castor 3-3 is subject to the downward pressure of pressing plate 3-2, but can in draw-in groove, with respect to fast pulley 3-1, rotate.
At worm-and-wheel gear after long wearing and tearing, between worm and gear, can produce gap, in order to guarantee certain precision, rotary disk 3 is provided with gap adjusting mechanism on said structure basis, and gap adjusting mechanism comprises a retaining mechanism and is distributed on the some tensioning mechanisms on rotary disk 3.
Tensioning mechanism comprises steady post I b3, steady post II b1 and is connected to steady post I b3 and the steady extension spring I b2 between post II b1, on castor 3-3, be provided with the through hole that diameter is greater than steady post I b3 diameter, to guarantee that steady post I b3 leaves certain activity surplus in through hole.Steady post I b3 is connected with fast pulley 3-1 through through hole and the end of castor 3-3, and it is upper that steady post II b1 is connected to castor 3-3, and steady post II b1 is positioned at steady post I b3 position along the place ahead in rotary disk 3 axial rotation directions.
Retaining mechanism comprises fixed block I a1, fixed block II a3 and skewback a2, fixed block I a1 is connected on castor 3-3, fixed block II a3 is connected on pressing plate 3-2, fixed block I a1 is positioned at fixed block II a3 position along the place ahead in rotary disk 3 axial rotation directions, skewback a2 is clipped between fixed block I a1 and fixed block II a3, the inner end of skewback a2 is connected with one end of extension spring II a4, extension spring II a4 along rotary disk 3 radially arrange and the other end to be connected to pressing plate 3-2 upper, skewback a2 from inner end outward width increase gradually.
When worm and gear produces gap because mutually wearing and tearing, steady post I b3 strains steady post II b1 by extension spring I b2, steady post II b1 drives castor 3-3 to rotate along the direction of rotary disk 3 axial rotation, thereby elimination gap, makes worm-gear toothing and the engagement of the tooth on worm screw on castor 3-3 circumference tightr.Simultaneously, extension spring II a4 tension skewback a2, make the wider part of skewback a2 move up to make up because castor 3-3 rotates the gap of causing, thereby keep the two sides of skewback a2 and the close contact of fixed block I a1 and fixed block II a3 side, play locking effect, prevent that worm gear reverse from causing the damage to rotary disk 3.
The above is only the preferred embodiment of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
