Description

Technical Field

[0001] The invention relates to the technical field of screw rod assembly, in particular to a quick assembly device for a screw rod and a jacking pipe. Background Art

[0002] A ball screw is a highly efficient mechanical transmission device that converts rotational motion into linear motion. It is widely used in CNC machine tools, automation equipment, robotics, and other fields. It primarily consists of a screw, balls, and a nut. When assembling a ball screw, it is crucial to ensure the precision of each component and the precise assembly process to ensure efficient transmission, long life, and stability.

[0003] After searching, it was found that the ball screws in the prior art are mostly filled with balls manually before leaving the factory. During the filling process, there are roughly two methods. One is to apply grease to the inner wall of the nut sleeve and then place the steel balls one by one. The other method is to use a false column to slowly pour the steel balls directly into the inside, and then move the steel balls into the ball groove. There is no doubt that the second method is more efficient, but this method will cause a large amount of steel balls to be scattered if the hand slips or dumps at any link. Therefore, we propose a stable and quick assembly device. Summary of the Invention
