Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, an embodiment of the present invention is shown: the utility model provides a device of supplementary ball screw assembly, including solid fixed cylinder 1, solid fixed cylinder 1's top is rotated and is installed rotatory piece 2, sliding tray 6 has been seted up to gu fixed cylinder 1's surface symmetry, sliding tray 6's internally mounted has lug 7, sliding tray 6's inside slidable mounting has sliding block 8, sliding block 8 is close to solid fixed cylinder 1's one end and has seted up recess 9, sliding block 8 keeps away from solid fixed cylinder 1's one end and installs connecting rod 3, limiting plate 4 is installed to two connecting rod 3 relative one ends, the surface of limiting plate 4 has seted up threaded hole 5, ball hole 10 has been seted up at solid fixed cylinder 1's top, solid fixed cylinder 1's top center department has seted up through-hole 11.

In this embodiment, the rotary block 2 is provided with a communication hole corresponding to the ball hole 10 and having a shape matching the ball hole, so that the ball can enter the ball screw through the ball hole 10.

In this embodiment, the ball hole 10 is a plurality of holes having different diameters, and the ball hole 10 can be paired according to a desired size of the ball.

In this embodiment, the screw holes 5 of the limiting plates 4 are fixedly connected by bolts, so that the ball screw can be clamped by the limiting plates 4.

In this embodiment, the slide block 8 and the slide groove 6 are adapted in shape and position, and the slide block 8 can be slid into the slide groove 6.
