The utility model discloses restrict the clearance between the lead screw screw thread with adjusting nut for lead screw reciprocating motion, motion transmission precision improves greatly, has reduced reciprocating motion's positioning error in the use, lets ordinary screw drive's precision provide and becomes convenient, stable, reliable and easy the realization, with the bearing settled on the leading truck axial displacement at vice guide shaft excircle, the frame pivoted degree of freedom is removed in the restriction, before having avoided some in test the instrument destabilizing factor to the influence of the influence of experiment.
Description
Technical field
This utility model relates to a kind of balanced controls, disappears gap balanced controls particularly to a kind of screw rod transmission.
Background technology
The textile instrument upper screw rod transmission that is applied to before existing disappears gap balanced controls, and employing is the axially in parallel design at capstan and screw axis, and considers the distance between two axles, the impact of the situation that swings small during on screw rod transmission.Such device, have the disadvantage that 1. in actual use procedure owing to the precision of common screw mandrel self limits, some gaps are always had during wire rod thread is secondary, during screw rod transmission, unidirectional displacement accuracy is high, such gap can bring about many problems when moving back and forth, and the positioning precision of the transmission of reduction, so limiting the application of some occasions.2. such wire rod thread vice mechanism, the swing about also producing the while of when motion simultaneously, the execution unit being so contained on the movable stand on nut will swing, the precision of the work of impact, reduces the reliability of textile instrument experiment.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, a kind of screw rod transmission is provided to disappear gap balanced controls, the bearing disposed on leading truck moves axially secondary guide shaft cylindrical, the degree of freedom that moving-limiting frame rotates, the screw that regulates on adjusting nut regulates the distance between adjusting nut and feed screw nut, it is possible to effectively solve the problem in background technology.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model provides a kind of screw rod transmission to disappear gap balanced controls, including the leading truck that movable stand and movable stand side are arranged, described movable stand is provided with guide pin bushing and feed screw nut, described guide pin bushing is provided with capstan, described feed screw nut is provided with screw mandrel, described screw mandrel is provided with adjusting nut, and described feed screw nut connects adjusting nut by regulating screw;Described leading truck is provided with two bearings and secondary guide shaft.
As a kind of optimal technical scheme of the present utility model, described screw mandrel is located in feed screw nut, and described adjusting nut is located on screw mandrel.
As a kind of optimal technical scheme of the present utility model, two described bearings are arranged on secondary guide shaft surface.
Compared with prior art this utility model reaches to provide the benefit that: the adjustment screw on this utility model adjusting nut is to regulate the distance between adjusting nut and feed screw nut, so limit the gap between wire rod thread, screw mandrel is moved back and forth, motion transmitting accuracy is greatly improved, decrease reciprocating position error in using, allow the precision offer of common screw rod transmission become convenient, stable, reliably and easily to realize;With the bearing disposed on leading truck moving axially at secondary guide shaft cylindrical, the degree of freedom that moving-limiting frame rotates, eliminate and reduce the secondary amplitude swung when transmission of screw nut driving, mechanism is simple, easy, convenient, can easily be accommodated, it is to avoid before some in test instrument unstable factor impacts on the impact of experiment.
