Description
Technical field
The utility model is related to ball-screw technical fields, easy to operate more particularly to a kind of structure design exquisiteness
Ball screw assembly, locking mechanism.
Background technology
Ball screw assembly, be it is a kind of between leading screw and pair of nut using ball as the worm drive structure of rolling element, in leading screw
With arc helicla flute is machined on nut, spiral rolling track is formed when they are set in together, and ball is loaded onto in raceway.When
When leading screw is to nut relative rotation, then nut produces axial displacement, and ball is then along rolling path rolling.The helicla flute of nut
Both ends are connected with ball-returning device, enable ball shuttling movement again and again, and the both ends of pipeline also play a part of block bead,
It is dropped out to prevent ball along raceway.
In the operational process of ball-screw, due to running at high speed for ball, nut and leading screw, make the temperature of ball-screw
Rise, leading screw and nut generate axial elasticity deformation and minim gap, can all influence ball-screw overall operation precision and
Service life, it is therefore desirable to be pre-tightened, reduce the gap between ball screw assembly, by pre-stretching, improve precision.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, the utility model provides a kind of ball-screw

The operation stability and transmission accuracy of ball screw assembly,.
Technical solution：To achieve the above object, the technical solution adopted in the utility model is：
A kind of ball screw assembly, locking mechanism, it is characterised in that：Including leading screw, nut and several balls, the nut set
It is located on leading screw, leading screw and nut are respectively provided with the helical guide groove for installing ball, and the is symmetrical arranged on the outer wall of the nut
One arc casting die and the second arc casting die and several connectors, one end of connector connect the first arc casting die or the second arc pressure
Part, connector the other end be equipped with Regulation Control component, Regulation Control component be used for connector apply pressure, the first arc pressure
Several springs are uniformly arranged between part and the second arc casting die and the outer wall of nut.
Preferably, one end setting external screw thread that the connector is connected with the first arc casting die or the second arc casting die
And lock screw, lock screw are used to finely tune the pressure that connector applies the first arc casting die or the second arc casting die.
Preferably, pressing plate is set between the connector and Regulation Control component.
Preferably, the Regulation Control component includes control cabinet and the mini cylinder equipped with pooling feature, mini cylinder
