Description
Technical field
The utility model relates to a kind of laser process equipment that is used for the surface of roller texturing, particularly a kind of laser process equipment with the surface of roller texturing that can process random texturing point.
Background technology
YAG laser roughening equipment is the cold roll laser process equipment of Inst. of Mechanics, CAS in the nineties research and development, as: China Patent No.: ZL 92113223.9, title: " high frequency modulation multy-pulse YAG laser engraving design system and processing method "; China Patent No.: ZL94220848.X, title: " laser process equipment that is used for the roller surface texturing ".Fig. 1 is the general structure schematic diagram of this equipment.This equipment adopts the high power laser impulse action of high repetition frequency in roller surface, produces the little hole of reinforcement (texturing point) of countless certain patterns on roll surface.This equipment class is similar to engine lathe.Its course of work is that spindle motor of machine tool drives the roll rotation, drives the laser head translation on the movable stand simultaneously, and acousto-optic power supply control laser instrument sends the laser pulse of fixed frequency, thereby gets the helix that is made of the texturing point of a uniform pitch on roll.Fig. 4 be the texturing point shape appearance figure that utilizes the cold roll surface that this method beats (about representative axially, represent circumferential up and down, down together), be referred to as uncontrollable distribution texturing point shape appearance figure, claim that correspondingly Fig. 4 is uncontrollable distribution laser roughening outfit of equipment structural representation.By finding out among the figure, the texturing dot spacing on each circle is equal substantially.This is because laser pulse frequency is fixed speed of mainshaft substantially constant.Because the control of the acousto-optic power supply of control laser instrument and the control of main axis rotation are separate, do not realize Synchronization Control, and speed of mainshaft steady speed precision are limited, causes the error of texturing point point distance.This error adds up on the whole piece helix, so the distribution of the texturing point between each circle does not have rule, but certain rule is arranged, and undulate distributes.
And for example: China Patent No.: ZL 00128273.5, title: " the surface of roller texturing laser-processing system with controlled distribution texturing point "; China Patent No.: ZL 00264774.5, title: " the laser processing device that is used for the surface of roller texturing " with controlled distribution texturing point.Fig. 2 is the general structure schematic diagram of this equipment.Fig. 5, Fig. 6 are the texturing point shape appearance figures that utilizes the cold roll surface that this method beats, this equipment is by adorning the incremental encoder of a high-accuracy high-resolution in the main shaft coaxial direction, and realizes the controlled distribution of roll surface texturing point with an industrial computer guide sound photoelectric source and movable stand.
Experiment shows that the distribution of texturing point is very big to the performance impact of texturing plate.Texturing plate with uncontrollable distribution texturing point, the performance of its each position and all directions thereof has than big-difference, also is that the isotropism of texturing plate is bad; Texturing plate with controlled distribution texturing point is compared with the texturing plate of uncontrollable distribution texturing point, has solved the uniformity problem that the texturing point of texturing plate distributes, in the same unit are of each correspondence the distribution of texturing point identical, its isotropism has bigger improvement.The equidirectional performance of its each corresponding position is consistent, but the performance of the different directions of each corresponding position still has than big-difference, and the performance difference of corresponding position and all directions thereof is not bigger for each.
More than the texturing point of two kinds of texturing plates distribute certain rule all arranged, make the outward appearance of texturing plate all directions inconsistent, directionality is arranged, and often needs the direction-free laser roughening plate of outward appearance in the reality.But existing equipment and processing method can't be processed the texturing point of random distribution at surface of roller.
