Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the sleeve push rod type ball screw assembly includes a nut 5, a disk 4 is disposed on an outer surface of one side of the nut 5, a screw 1 is disposed on an inner surface of a middle portion of the nut 5, stress mechanisms 2 are disposed on outer surfaces of peripheries of the nut 5, a lifting bolt 3 is disposed on an outer surface of a middle portion of the stress mechanism 2, a supporting plate 9 is disposed on an outer surface of a middle portion of the lifting bolt 3, a movable pressing plate 7 is disposed on one side of the stress mechanism 2, a movable shaft 8 is disposed on an outer surface of one side of the movable pressing plate 7, a fastening bolt 6 is disposed on an outer surface of the other side of the movable pressing plate 7, a first through hole 10 is disposed.
Further, the surface of one side of movable clamp plate 7 passes through loose axle 8 and nut 5's surface swing joint, and the surface swing joint of the opposite side surface of movable clamp plate 7 through fastening bolt 6 and nut 5 is favorable to more convenient when carrying out the dismouting operation to prevent that spare part from losing.
Furthermore, the outer surface of the stress mechanism 2 is movably connected with the outer surface of the nut 5 through the lifting bolt 3, so that the stability in use can be better ensured.
Furthermore, the number of the first through holes 10 and the number of the second through holes 11 are several groups, which is beneficial to improving the adaptability of practical use.
Furthermore, the ball is arranged inside the nut 5, so that the smoothness of overall adjustment can be better guaranteed.
Furthermore, the outer surface of the lead screw 1 is provided with a screw groove, which is beneficial to ensuring the stability of the rotation of the ball.
The working principle is as follows: when in use, the screw 1 can be firstly connected with a corresponding mechanism or equipment, then the disc body 4 can be connected with a corresponding actuating mechanism, finally, when the nut 5 rotates and displaces, the inner ball can roll along the thread groove on the surface of the screw 1, so as to drive the whole position of the nut 5 to change, in the actual use process, the inner ball is inevitably blocked or unsmooth in circulation, aiming at the problem, the inner ball can be adjusted through the movable pressing plate 7, the fastening bolt 6 can be unscrewed in the actual operation, so that the movable pressing plate 7 can be opened through the movable shaft 8 but can not fall off, and the rotation condition of the inner ball can be directly checked, so as to consider whether the ball needs to be replaced or not, or maintain or replace the inner structure of the nut 5, compared with the traditional similar structure, the movable shaft 8 can avoid falling off when the movable pressing plate 7 is opened, therefore, the disassembly and assembly are more convenient, because the whole outer surface of the existing nut 5 is smooth, the sufficient firmness cannot be ensured when the surface of the existing nut 5 is directly grasped or limited to adjust the position, the problem can be improved through the stress mechanism 2, the lifting bolt 3 is rotated in the actual operation, because the stress mechanism 2 is separated from the lifting bolt 3, the stress mechanism 2 can be synchronously lifted through the supporting sheet 9 when the lifting bolt 3 is lifted, so that the surface of the nut 5 can form a bulge, the rotation adjustment of the outer surface of the nut 5 can be more convenient and rapid directly, when the existing disk body 4 is connected with other structures or equipment, only holes with fixed radius are formed on the surface of the existing disk body, the practical use limitation is larger, and the problem can be improved through the first perforation 10 and the second perforation 11, since the first through hole 10 and the second through hole 11 have different radii and different distribution positions, they can be selected according to different connection requirements, thereby achieving better connection effect.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
