Full automatic U-shaped part and steel ball assembling line
Technical field
The present invention relates to a kind of Full automatic U-shaped parts and steel ball assembling line.
Background technique
In sliding rail production field, it usually needs production and processing is some for reducing the device of frictional resistance.Such as it wants
Slide unit is placed on the table, and slide unit can slide on the table, that, which just needs to install in slide unit lower surface, slides
Component is to facilitate slide unit to slide.Slide assemblies commonly used in the prior art are from section to form with U-shaped pedestal and steel ball,
Steel ball is assemblied in the open slot of U-shaped bottom seat;Then, pedestal is mounted on slide unit lower surface, steel ball is towards workbench and can
To roll on the table;So, steel ball can freely roll between the pedestal and table surface of slide unit lower surface
It is dynamic, sliding of the slide unit relative to workbench is realized, and then reduce frictional force when slide unit is slided relative to workbench, so that the two
Between relative motion it is more smooth.In some specific occasions, need to be put into spring between steel ball and pedestal to play buffering
The purpose of damping, this just increases workload to the assembly of slide assemblies.And in actual assembled U-shaped bottom seat and steel ball, usually
It is that artificial crawl spring is first put into U-shaped bottom seat, then is picked up steel ball and be put into U-shaped bottom seat, such working efficiency is lower, from
Dynamicization is horizontal relatively low, is unfavorable for mass production processing.
