The present invention features that the motion in both vertical direction and horizontal direction is simplified into the motion in only vertical direction. The present invention has reasonable design, compact structure simple operation and other advantages, and is suitable for use in different kinds of counter weight mechanism with rope.
Description
(1) technical field
The present invention relates to the mechanical counterweight parts, concrete relating to is a kind of by the alternative underslung vertical numerical controlled lathe Z shaft counterweight mechanism of single direction of pulley combination change counterweight motion mode.
(2) background technology
Counterweight is plant equipment a kind of operation balance mode comparatively commonly used, and different because of the profile of machinery, the performance of equipment has nothing in common with each other again, thereby the mode of counterweight, method are also the same not to the utmost.Because of simple in structure, easy for installation its advantage is arranged in the use as underslung counter weight device,, also adopt underslung counter weight device up till now mostly such as vertical lathe so range of application is extensive comparatively more.Because the motion of vertical lathe Z-direction is perpendicular to ground, Z axle servomotor also will be born the weight of each parts on the Z axle except that needs are born the required machining load of workpiece cutting.The method of numerical control vertical lathe and machining center head it off roughly has two kinds at present: a kind of is to adopt balancing cylinder, and a kind of is the purpose that reaches weight balancing with more traditional suspension type counterweight.
Bent motion in vertical lathe Z axle is to be superimposed upon on the horizontal movement of X-axis, forms the resultant motion of four direction up and down, so the motion of counterweight also is the motion of four direction.Adopt the advantage of counterweight mode counterweight to be: simple in structure, be difficult for breaking down.In vertical direction, owing to link together between counterweight and the Z thrust load or with steel wire rope or with chain, steel wire rope or chain are in tensioned state all the time, and no matter up or down the Z axle motion, can not produce excessive vibration.But the motion of horizontal direction X-axis is just different, because the Z axle will move up and down, counterweight will have fixing rail plate that moves up and down or guide pillar, counterweight can make counterweight produce and the opposite impulsive force of X-axis horizontal movement direction with gap between guide rail or the guide pillar, cause the vibration of lathe, if and this excesssive gap, then can produce the double swerve of large amplitude.
Because of counterweight produces the long term that impacts, can produce a lot of adverse consequences: the drive disk assembly to lathe causes damage; The gap is increasing, directly the precision of influence processing; The also corresponding burden that increases servomotor.
If cancelled the motion of counterweight horizontal direction, not only saved installing space, the more important thing is the harm of having avoided impact shock to bring to lathe, install more simple and conveniently, also reduced requirement to balance weight mechanism guiding.
(3) summary of the invention
The present invention is in order to solve the existing shortcoming of suspension type ballasting method and the problem of present use, and a kind of fitting operation that makes things convenient for is provided, and can prolong service life of equipment, safe and reliable again vertical numerical controlled lathe Z shaft counterweight mechanism.
The technical scheme that adopts is:
Vertical numerical controlled lathe Z shaft counterweight mechanism comprises pulley gearing, hanging apparatus, bascule; Described pulley gearing comprises suspension sheave, deflecting roller, two suspension sheave I are connected with other two suspension sheave II respectively by outstanding rope, suspension sheave I and suspension sheave II all are positioned on the support, support is positioned at the top of lathe bed body, two deflecting rollers are set in the bottom of support back, two deflecting rollers are connected with two suspension sheave II respectively by outstanding rope, below deflecting roller, be equiped with two directive wheels, two deflecting rollers are connected by outstanding rope with two directive wheels respectively, the below of two directive wheels is provided with two fifth wheels, two fifth wheels are connected directive wheel with two directive wheels respectively by outstanding rope, fifth wheel be positioned at the back upright of lathe bed body and.Bottom at two fifth wheels is provided with a movable pulley, and movable pulley is connected with two fifth wheels by outstanding rope.
Described hoisting mechanism, be that the slide plate lifting of two suspension sheave I by standing before hanging rope and being positioned at the lathe bed body is connected, turret is fixedlyed connected with slide plate, and slide plate is slidingly connected by guide rail and saddle, and saddle is fixedlyed connected with support and is integral and is slidingly connected by guide rail and lathe bed body.
Described balanced controls are to be positioned at that the movable pulley and the counterweight of facade directly links behind the lathe bed body.
The operating principle of vertical numerical controlled lathe Z shaft counterweight mechanism:
1, slide plate vertical lift: moving both vertically about the slide plate finished by Z axial filament thick stick, and the servomotor of Z axle drives leading screw and rotates, thereby realizes moving up and down of slide plate.When only having slide plate to move up and down, movable pulley does not rotate, and movable pulley is moving up and down and do rightabout motion with slide plate only.Be slide plate when moving upward, counterweight is downward with movable pulley, and when slide plate was downward, counterweight made progress with movable pulley.At this moment, other pulleys except that movable pulley all do not have in locational relative motion, and all pulleys just play the guide-localization effect to suspension cord, only have movable pulley to move up and down.
2, the horizontal motion of saddle:
The motion that the horizontal X axial filament thick stick of lathe drives saddle, support and all places the parts on the saddle to produce horizontal direction, two groups of suspension sheaves with one group of deflecting roller simultaneously with saddle support horizontal motion, these three groups of pulleys and all placed between the pulley on the lathe bed body and produced relative motion this moment, and variation has taken place relative position.
When saddle moves right, distance shortens between the deflecting roller on right side and the directive wheel, and rope has lax trend, but the rope on whole right side is because of being subjected to pulling of both sides weight, again can be with the rope stretch that is tending towards relaxing, the weight of both sides can produce the trend that moves downward separately.Meanwhile, situation is just the opposite with it for the rope in left side, because of the deflecting roller in left side and the distance increasing between the directive wheel, be that the right side is apart from what shorten, how many left side distances just strengthens, the rope in left side can upwards draw high the weight of side-by-side mounting, produces movement tendency upwards, has stoped the movement tendency that produces because of the right side line relaxation.This moment, the adjusting work of both sides rope length was finished by the rotation of movable pulley.
Of the present invention being skillfully constructed, reasonable in design, compact conformation, easy for installation, debugging easily, noise and resistance are all very little during easy to maintenance, pulley combination work.Be applicable to the plant equipment of various wire-hanging type counterweights.The present invention is that the motion with the four direction up and down of counterweight or mass is reduced to the motion of both direction up and down; this also is a key point of the present invention; need to prove; under the prerequisite that does not change present principles; can also make some changes or distortion to the present invention, this belongs to protection scope of the present invention equally.
