Abstract

The invention provides a measuring and calibrating device for laser processing focal length and incidence angles. The device comprises a telescopic measuring ruler, a connecting rod piece and an upper measuring ruler. The telescopic measuring ruler comprises a fixed part and a movable ruler part. A laser beam incidence perpendicularity calibrating hole penetrating the movable ruler part is formed in the extension end of the movable ruler part, and concentric annular targets are arranged outside the upper hole surface and the lower hole surface of the laser beam incidence perpendicularity calibrating hole. An alignment part is arranged on the upper measuring ruler and used for aligning at a reference marked line on a laser processing head. The connecting rod piece is hinged to the fixed part of the telescopic measuring ruler and the upper measuring ruler and used for connecting the telescopic measuring ruler with the upper measuring ruler, then the measuring directions of the telescopic measuring ruler and the upper measuring ruler are parallel, and the distance between the telescopic measuring ruler and the upper measuring ruler can be adjusted and measured. Multiple measuring and calibrating manners are organically integrated, precise measuring and positioning of the laser processing focal length and incidence angles are achieved, the laser processing focal length and incidence angles are tightly combined together, measuring, adjusting and calibrating of the laser processing focal length are very convenient, and operation is easy.

Description

technical field [0001] The invention belongs to the field of laser processing, and in particular relates to a measuring and positioning device for laser processing focal length and incident angle. Background technique [0002] Laser processing technology is a technology that uses the characteristics of the interaction between laser beams and substances to cut, weld, surface treat, drill, and micro-process materials (including metals and non-metals). As an advanced manufacturing technology, laser processing has been widely used in important sectors of the national economy such as automobiles, electronics, electrical appliances, aviation, metallurgy, and machinery manufacturing. It has played an increasingly important role in improving product quality, labor productivity, automation, pollution-free, and reducing material consumption. important role. [0003] Laser processing head is the general term for all kinds of processing heads in laser processing methods (welding, cutti...
