Abstract

The invention relates to a locating dustproof mechanism for ball screw rod return flow component, jacketing a screw cap main body on a ball screw rod with rolling screw channel, where the inner edge of the screw cap main body has a corresponding rolling screw channel and the end of the rolling screw channel of the screw cap main body is formed with a return flow hole, the return flow hole is fixed with a return flow component; the screw cap main body forms a thimble groove, the thimble groove is inserted with an annular fixed scraping piece; the fixed scraping piece is composed of a C-shaped buckle, the outer edge of the buckle is covered with an elastic soft coating and the thickness of the soft coating is greater than the width of the thimble groove so as to make the fixed scraping piece able to be fixed and closely butted against the side surface of the return flow component; the inner edge of the soft coating is formed with a spiral scraping part corresponding to the rolling screw channel of the ball screw rod, and the soft coating forms an arch-shaped scraping edge corresponding to the spiral wall surface and outer diameter of the ball screw rod at one side edge of the spiral scraping part. And the invention uses elasticity of the soft coating to fasten the return flow component in the screw cap main body and has dustproof effect.

Description

Technical field

[0001] The invention relates to a positioning and dustproof mechanism of a ball screw return assembly, in particular to a special design of a fixed wiper that can simultaneously press the return assembly and dust removal, which can solve the problem that the structure of the conventional return assembly fixing and wiper is too complicated The problem can be simplified and the structure can be simplified. Background technique

[0002] The ball screw has excellent mobility and precision. It is widely used in various places requiring precise displacement, such as saddles of various manufacturing and processing machines. At the same time, it is also developing in the direction of miniaturization and simplified structure. . The conventional ball screw is mainly composed of a ball screw and a nut body screwed on it. Both ends of the nut body are respectively provided with return components for guiding the return and flow of the balls. The return components are locked by...
