Abstract
The utility model discloses a ball screw is vice, including ball nut, the steel ball, wherein ball nut is a long sleeve nut, ball screw thread raceway portion processing has the mounting groove of installation cutting ball return ware, the cutting ball return ware is installed in ball screw's mounting groove, ball nut thread raceway and cutting ball return ware form the circulation raceway groove, every circulation raceway inslot is filled with the steel ball, the steel ball will cross ball nut's path when the cutting ball return ware returns, the axial thrust who changes ball nut with ball screw's torque through the steel ball. The utility model discloses simple structure, safe and reliable have and are applicable to some space dimensions and little, and ball nut external diameter and terminal surface do not allow the advantage that uses under the condition of processing ball return device mounting hole again.
Description
Technical Field
The utility model belongs to the vice field of ball.
Background
At ball screw substructure commonly used at present, the ball returning device is installed on ball nut, the steel ball circulates in ball nut raceway, the number of turns of ball nut thread raceway is few, the number of turns of ball screw thread raceway is many, and ball nut runs along the lead screw. However, in the case that the outer diameter and the end face of the ball nut are small in space size and do not allow machining of the ball return device mounting hole, the ball return device is mounted on the ball screw.
Disclosure of Invention
The utility model discloses having used for reference the design principle that traditional ball is vice, provided a ball is vice, will cut the strip and return the pearl ware and install on ball, have simple structure, safe and reliable, be applicable to some little space sizes.
The technical scheme of the utility model is that: the utility model provides a ball screw is vice, including ball nut, the steel ball, characterized by ball nut is a long sleeve nut, ball screw thread raceway portion processing has the mounting groove of installation cutting ball return ware, the cutting ball return ware is installed in ball screw's mounting groove, ball nut thread raceway and cutting ball return ware form the circulation raceway groove, every circulation raceway inslot is filled with the steel ball, the steel ball will cross ball nut's path when returning through the cutting ball return ware, the axial thrust who changes ball nut with ball screw's torque of revolution through the steel ball.
Furthermore, according to the size of the load, the cutting bead returning device with different lengths can be installed.
The utility model discloses following beneficial effect has:
1. the utility model discloses having used for reference the design principle that traditional ball is vice, vice opposite with traditional ball, having installed the vice ball ware that returns of traditional ball on ball nut and changing into 1 cutting and returning the ball ware and install on ball, the ball screw thread is shorter, and ball nut designs into a long box nut, and the during operation steel ball circulates on ball, and ball screw rotation ball nut makes linear motion, and ball nut external diameter can carry out all kinds of sealings.
2. The utility model discloses simple structure, safe and reliable have and be applicable to some space dimensions little, and ball nut external diameter and terminal surface do not allow the advantage that uses under the condition of processing ball ware mounting hole again.
Drawings
FIG. 1 is a schematic diagram of a ball screw assembly.
The reference numbers illustrate: 1. a ball nut; 2. a cutting and bead returning device; 3. a steel ball; 4. a ball screw.
Detailed Description
As shown in fig. 1, the ball nut 1 is designed as a longer sleeve nut, the thread raceway portion of the ball screw 4 is provided with a mounting groove for mounting the slip ball returning device 2, the slip ball returning device 2 is mounted on the ball screw 4, and the slip ball returning devices 2 with different lengths can be mounted according to the load.
When the device is used, when the ball screw 4 rotates, the steel ball 3 circularly rolls in a circular track groove formed by the ball screw 4, the thread track of the ball nut 1 and the slip ball returning device 2, the steel ball 3 needs to cross over the small diameter of the ball nut 1 when returning through the slip ball returning device 2, the ball screw 4 rotates, the ball nut 1 makes linear motion, and the rotating torque of the ball screw 4 is converted into the axial thrust of the ball nut 1 through the steel ball 3.
Claims (2)
1. The utility model provides a ball screw is vice, including ball nut (1), steel ball (3), ball (4), characterized by ball nut (1) is a long sleeve nut, ball (4) screw thread raceway portion processing has the mounting groove of installation cutting ball returning device (2), cutting ball returning device (2) are installed in the mounting groove of ball (4), ball nut (1) screw thread raceway and cutting ball returning device (2) form the circulation raceway groove, every circulation raceway inslot is filled with steel ball (3), the path of ball nut (1) will be crossed when steel ball (3) return through cutting ball returning device (2), the axial thrust of ball nut (1) is converted into with the turning moment of ball (4) through steel ball (3).
2. The ball screw assembly according to claim 1, wherein the slip ball returner (2) having different lengths is installed according to the load.
