Abstract
The utility model of clearance removable combined nut is a combined nut mounted between a moving form and a guide screw of mechanical equipment, including a mother nut, a deputy nut, an elastomer, and a pressing plate. The elastomer is arranged between the mother nut and the deputy nut which is provided with the pressing plate at the outside of the deputy nut. The pressing plate pressing the elastomer and the deputy nut is connected with the mother nut via a bolt, so that the mother nut, the elastomer, the deputy nut, and the pressing plate are connected to form a whole piece along axial direction. The combined nut is connected with the driven moving form, the screw or the guide screw screwed in the combined nut. The utility model could not only slake the clearance between the nut and the guide screw or the nut, but also have the function of self compensation; at the same time, the utility model with simple structure and low manufacturing cost has a certain generalizing and using value.
Description
Technical field:
The assembled nut that the utility model can be eliminated the gap is that a kind of screw mandrel or screw rod of being used for matches with nut and form the assembly of gapless transmission feeding device, belongs to machinery and makes the field.
Background technique:
The transmission device that existing screw mandrel or screw rod and nut are formed, particularly the bistrique of glass machinery industry grinds the seat work feeder, owing to exist fit up gap and wearing clearance between screw mandrel and the nut, make the actual amount of feed and the numerical value on the dial have error, directly influenced machining accuracy, and the mechanism in existing elimination screw mandrel and nut gap, voussoir normally is set between two nuts or simply uses spring to eliminate the gap, the mode of these adjusting plays, the ubiquity adjustment is inconvenient and can't eliminate the defective in gap fully.
Summary of the invention:
For improving the deficiencies in the prior art, the utility model has designed a kind of assembled nut of eliminating the gap, and it not only can compensate automatically, eliminate the gap between nut and the screw mandrel fully, have simple in structurely simultaneously, advantage of low manufacturing cost has certain popularizing value.
The utility model can be eliminated the assembled nut in gap and realize by following measure, it is mounted in the assembled nut between machinery moving body and the screw mandrel, it comprises mother nut, secondary nut, elastomer and pressing plate, elastomer is contained between mother nut and the secondary nut, pressing plate is equipped with in the outside of secondary nut, pressing plate is connected with mother nut by screw, and makes elastomer, secondary nut pressurized, thereby mother nut, elastomer, secondary nut and pressing plate are fused vertically.
Assembled nut is installed by following method and is formed: at first mother nut is screwed on screw mandrel or the screw rod, then elastomer is inserted in screw mandrel or screw rod, and with on secondary nut screw-in screw mandrel or the screw rod, free-hand or secondary nut precession is made the master with instrument, its bi-side of elastomer between the secondary nut hold out against is leading, on the inner side surface of secondary nut, and generation compressive strain, at this moment the resistance between assembled nut and screw mandrel or the screw rod is very big, even very difficult turn, then pressing plate is penetrated screw mandrel or screw rod and pressing plate is pressed on the outer side surface of secondary nut, with screw itself and mother nut are fixed, screw-in along with screw, pressing plate presses the strength of secondary nut constantly to increase, resistance during the assembled nut rotation can reduce thereupon, whole assembled nut can easily rotate along screw mandrel or screw rod this moment, pull down assembled nut, can eliminate the assembled nut in gap with regard to installation this moment.
Earlier assembled nut is connected with driven moving body during use, then screw mandrel or screw rod screw-in assembled nut are screwed bridge screw gently, gap between screw mandrel or screw flight and the whole assembled nut can be more and more littler, make whole screw mandrel or screw rod dextrorotation or derotation, whether eliminate with setting about the sympathetic gap of judging, the gap does not need to compress by force when disappearing to proper states again, hinders screw thread in order to avoid squeeze.
The utility model can be eliminated the assembled nut in gap, and it not only can eliminate the gap between nut and screw mandrel or the screw rod, simultaneously also can be in the compensation automatically of the female wearing and tearing of nut back.
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing 1 is the utility model embodiment plan view.
Accompanying drawing 2 is that the utility model is implemented the A-A sectional view.
Accompanying drawing 3 is the utility model scheme of installations.
The utility model can be eliminated the assembled nut in gap as shown in Figures 1 and 2, it is mounted in the assembled nut between machinery moving body A and the screw mandrel B, it comprises mother nut 1, secondary nut 2, belleville spring 3 and pressing plate 4, belleville spring 3 is contained between mother nut 1 and the secondary nut 2, the mother nut inner side surface has groove 11, belleville spring 3 uses in pairs and places groove 11, pressing plate 4 is contained in the outside of secondary nut 2, have attachment hole 41 on the pressing plate 4, have on the mother nut 1 with pressing plate on the corresponding screw 12 of circular hole, pressing plate 4 is fixing with mother nut 1 by screw 5, pressing plate 4 makes belleville spring 3, secondary nut 2 pressurizeds, thereby with mother nut 1, belleville spring 3, secondary nut 2 and pressing plate 4 fuse vertically.
The utility model can be eliminated the assembled nut in gap as shown in Figure 3, it is mounted in the assembled nut between machinery moving body A and the screw mandrel B, it is by mother nut 1, secondary nut 2, belleville spring 3 and pressing plate 4 are formed, earlier mother nut 1 is screwed on screw mandrel or the screw rod B during installation, then belleville spring 3 is inserted on screw mandrel or the screw rod B and it is installed in the groove 11 of mother nut inner side surface, with hand or with instrument secondary nut is screwed in then, make the master, belleville spring 3 compressive deformations between the secondary nut, at this moment the resistance between assembled nut and screw mandrel or the screw rod is very big, even very difficult turn; At last pressing plate is contained in the outside of secondary nut, make secondary nut 2 be subjected to the pressure of pressing plate by screwing screw 5, and pressing plate and mother nut be secured together, screw-in along with screw, pressing plate presses the strength of secondary nut constantly to increase, and the resistance when whole assembled nut rotates can reduce thereupon, and whole assembled nut can easily rotate along screw mandrel or screw rod, pull down assembled nut, can eliminate the assembled nut in gap with regard to installation this moment.Earlier assembled nut is connected with driven moving body A during use, then screw mandrel or screw rod screw-in assembled nut are screwed bridge screw gently, gap between screw mandrel or screw flight and the whole assembled nut can be more and more littler, make whole screw mandrel or screw rod dextrorotation or derotation, whether eliminate with setting about the sympathetic gap of judging, the gap does not need to compress by force when disappearing to proper states again, hinders screw thread in order to avoid squeeze.
