Description
Technical field
The utility model relates to a kind of gyrator, and especially a kind of sliding push type, with the gyrator of auto-lock function belongs to mechanical transmissioning technology field.
Background technique
At present conventional gyrator, all by the mode transferring power of gear transmission or ratchet driving, still adopts the gyrator protecting against shock ability of these two kinds of kinds of drive weak, does not possess auto-lock function.
Model utility content
The purpose of this utility model is to provide a kind of gyrator that possesses auto-lock function.This gyrator is applicable to realize the revolute function of numerical controlled machinery, industrial automation.
The utility model is achieved through the following technical solutions this object:
A gyrator, comprises casing, screw mandrel, turning axle, slide block; Screw mandrel, turning axle are all fixedly installed in casing rotationally, and all at least one end be positioned at outside casing; Slide block comprises the slider body that is provided with tapped through hole, and slider body is installed on screw mandrel; This turning axle periphery is provided with vertically the rotation guide groove of rotation, and slide block also comprises being positioned at least partly rotation guide groove and can acting on the ，Gai transmission unit, transmission unit and the slider body that rotate guide groove inwall and is fixedly linked; This gyrator also comprises that restriction slider body only can be along the axially movable guiding device of screw mandrel.
When external motive device is ordered about screw mandrel and rotated, because slide block and screw mandrel pass through screw-thread fit, and guiding device limits slide block, and slider body moves axially along screw mandrel; Slider body is along in the axially movable process of screw mandrel, and transmission unit rotates by acting on rotation guide groove inwall promotion turning axle, thereby promotes turning axle rotation.When external motive device is ordered about screw mandrel and rotated backward, transmission unit promotes turning axle counterrotating, thereby promotes turning axle counterrotating.Thereby realize revolute function.
In this gyrator, screw mandrel and slide block are threaded connection, and transmission unit rotates by acting on rotation guide groove inwall promotion turning axle, makes this gyrator transmission of power steady; On the other hand, adopt the mode transferring power being threaded between screw mandrel and slide block, this makes this gyrator possess auto-lock function.
Described transmission unit comprises the optical axis being fixed on slider body, and is socketed on the axle sleeve on optical axis; Described axle sleeve can act on rotation guide groove inwall.Preferably, the external diameter of axle sleeve equates with the groove width of rotation guide groove, to increase the protecting against shock ability of gyrator.
With respect to prior art, the utility model gyrator structures is simple, possesses auto-lock function.
