Description
Technical field
The utility model is related to a kind of machine tool guideway process for treating surface, through laser micro process, in machine tool guideway table
Face forms dimple hole texture and is spaced apart with microprotrusion texture, and has the very low power in connection dimple hole along machine tool motion directional spreding
Surface topography, and in particular to a kind of application of the micro- texture guide rail technology in surface in Machine Tool Industry.
Technical background
With the development of science and technology complex precise part demand amount dramatically increases, ground of the precision machine tool in machinery manufacturing industry
Position is very important.Machine tool guideway is complete machine key components, and performance directly influences machining accuracy and lathe service life.Lathe
Guide rail common deficiency includes that guide rail contact area is big, and film distribution is uneven, and adhesive wear increases guide pass and is in boundary lubrication shape
State, abrasion aggravation dynamic pressure or hydrostatic slideway surface, oil film is again blocked up, and guide rail floats excessively high, surface to be machined roughness increase, essence
Degree reduces in lubricating oil and is mixed into dust or chip, causes the scratch of guide pass and wears since lubricating oil is unevenly distributed, friction
Power, which mutates, occurs creeping phenomenon.Guide rail surface roughness exception, existing wear particle, generation adhesion, guide rail moment open
Dynamic wait can all cause to creep, but after all, the suddenly change of frictional force is the principal element of creeping phenomenon.
Chinese patent CN104551701A discloses a kind of compound micro- texture guide rail, orderly divides in the processing of guide rail working surface
The compound pattern that the dimple hole of cloth is constituted with dimpling shoulder.Although the presence of dimpling shoulder reduces confficient of static friction and kinematics and static friction
Coefficient difference inhibits creeping phenomenon to a certain extent, but dimpling shoulder so that there are gaps to lead to dimple intracavitary between lathe and guide rail
Oil storage be difficult to be carried over to form complete lubricating film, do not have the meaning of practical solution technical problem, make working surface instead
It is easy to wear.In addition the yield rate that recess but also the single texture with raised pattern had not only been carried during actual processing is low, processing
Difficulty is big, of high cost.
To solve single textural composite pattern processing difficulties, dimple hole oil storage, oil supply function are difficult to play and lubricating oil
The problem of flow difficulties, the utility model processes dimple chamber in quiet guide rail working surface using laser and microprotrusion texture is single
The surface topography that pattern is spaced apart, and it is being machined with the very low power pattern that connection dimple cheats texture along machine tool motion direction, promote
The oil storage, the fuel feeding that are distributed in entire guide rail working surface, effectively play that dimple is cheated for being allowed to be more uniformly distributed into the flowing of lubricating oil
Function is conducive to the formation of oil film, so as to improve greasy property, inhibits creeping phenomenon.
