It is widely used in life.

[0003] During the use of the existing ball screw slide, the ball body cannot be accurately positioned on the outer wall of the screw, resulting in offset during movement and reducing the accuracy. At the same time, when the screw drives the ball to move, the motor drives the screw to shake, causing the ball to slide on the outer wall of the screw to reduce the stability of the equipment.

[0009] As a preferred technical solution of the present invention: a square groove is provided on the inner wall of the block, and an outer wall of the square groove is in sliding connection with an outer wall of the tooth block.

[0010] As a preferred technical solution of the present invention: one end of the spring is fixed to the inner wall of the block, and the other end of the spring is fixed to the outer wall of the tooth block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The ball screw slide with precise positioning capability uses a controller to drive the fixed plate to rotate by a motor.

When the external force releases the fixed rod, the fixed rod pushes the tooth block through the elastic force of the spring, so that the tooth block and the outer wall of the gear are connected. The gear drives the screw body to stop rotating, and the positioning block is positioned by the ball body. BRIEF DESCRIPTION OF THE DRAWINGS
