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. 1-4, an embodiment of the present invention is shown: a flange-adjustable ball screw comprises a screw shaft 1, a nut 2 is installed on the outer surface of the screw shaft 1 in a threaded mode, and a flange plate 3 is installed at one end of the nut 2.

The ring flange 3 includes disk body 4, and the surface slidable mounting of disk body 4 has expansion board 5, and the surface of disk body 4 articulates there is rotatory piece 6, and strip shaped plate 7 is installed to the one end of rotatory piece 6 away from with 4 pin joints of disk body.

In the embodiment, a circulator and a steel ball are arranged in the nut 2, and the movement of the nut 2 on the screw shaft 1 is realized through the cooperation of the steel ball and the circulator.

In this implementation, the two sides of the disk body 4 are both provided with grooves matched with the expansion board 5, and the centers of the expansion board 5 and the disk body 4 provided with the grooves are provided with assembly holes communicated with each other, so that the expansion board 5 can slide on the disk body 4, and the effect of changing the assembly diameter of the flange plate 3 is achieved.

In this implementation, a plurality of through-holes have been seted up to the surface of strip shaped plate 7, and the surface of expansion board 5 is seted up with set up a plurality of screw holes of through-hole assorted on the strip shaped plate 7, can carry out fixed connection to expansion board 5 and strip shaped plate 7 through the screw.

In this embodiment, the outer surface of the tray body 4 is provided with a groove matched with the rotating block 6.

In this implementation, the quantity of expansion board 5 and rotatory piece 6 is four, and four mutual symmetries of expansion board 5 set up on disk body 4, and four rotatory pieces 6 are equallyd divide equally between adjacent expansion board 5, and then after 5 roll-offs of expansion board, through 6 upset play strip shaped plate 7 of rotatory piece, make two liang of adjacent expansion boards 5 can the reciprocal anchorage with the help of strip shaped plate 7, form firm installation face.
