Learn device.It is typically mounted in the rotation axis of motor during use, is rotated by the high speed of multiaspect scan prism, it can be achieved that big model
It encloses, ultrahigh speed, scanned in high precision with the laser beam of high duplication, the factors such as angle precision, surface quality will directly affect
Scanning accuracy and effect, thus it is very high to the angle requirement on machining accuracy of its each reflecting surface.
The processing of country's multiaspect scan prism relies primarily on the numerically controlled lathe with shaft and realizes at present, can once process number
Measure limited, angle precision between each face is ensured by the precision of numerical control shaft.The multiaspect scanning processed on numerically controlled lathe
During prism, in order to ensure the angle precision between each scanning plane, it is necessary to which clamped one time completes all side processing.It detects each
During scanning plane angle, if using being detected under line, if some scanning plane angle is overproof, it is necessary to clamping again, to scanning rib
Mirror is processed again, necessarily introduces new position error during clamping again, is that processing efficiency is low, detection efficiency is also low；In addition criticize
Homogeneity of product is poor during amount processing, seriously affects the stability of assembling equipment.
The content of the invention
It is an object of the invention to solve the position error of the introducing of multiple clamping to influence each scanning plane angle precision in angle
The problem of.
A kind of metal multiaspect scan prism processing method of achievable on-line checking, specific technical solution are as follows：
