Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 and figure 2 As shown, the method for calibrating orthogonal double pendulum axes applied to laser processing provided by the present invention is used to calibrate the quadrature error of the first pendulum axis and the second pendulum axis 5, and the method includes the following steps:

[0035] 1) Plane reflector 1 and autocollimator 1 are respectively arranged at both ends of the first pendulum axis, and the positions of plane reflector 1 and autocollimator 1 are adjusted so that the mirror surface of plane reflector 1 is aligned with the first pendulum The axis is vertical, so that the outgoing beam of the autocollimator 1 is parallel to the rotation axis of the first pendulum shaft; the rotation accuracy Δδ of the first pendulum shaft is measured by the autocollimator 12 1 .

[0036] 2) Plane reflector 2 3 and ...

Abstract

The invention provides an orthogonal double-pendulum shaft calibrating and debugging method as well as reflector assembling and adjusting method for laser processing. The calibrating method comprises the steps that a pentaprism is arranged at the intersection of the rotation axes of two pendulum shafts, and after the rotation axis of one of the pendulum shafts is reflexed by 90 degrees through the pentaprism, the actual included angle between the rotation axes of the two orthogonal pendulum shafts can be calibrated through an autocollimator arranged on the rotation axis of the other pendulum shaft. According to the orthogonal double-pendulum shaft calibrating and debugging method as well as reflector assembling and adjusting method for laser processing, special optical equipment do not need to be adopted when the actual included angle between the laser processing orthogonal double-pendulum shafts is calibrated, and the calibrating method is simple.

Description

technical field [0001] The invention belongs to the field of optomechanics, and relates to a method for calibrating and adjusting orthogonal double pendulum axes and adjusting mirrors for laser processing. Background technique [0002] In recent years, laser processing as an advanced manufacturing technology has been gradually applied to all aspects of production and life. Laser three-dimensional processing based on five-axis linkage laser processing machine tools represents the highest level of laser processing and manufacturing technology. Currently, five-axis linkage laser processing Machine tool technology is mainly mastered in industrially developed countries such as Europe, the United States, and Japan, and domestic research on five-axis linkage laser processing machine tools is on the rise. [0003] The dual-swing axis guide head commonly used in five-axis linkage laser processing machine tools has the advantages of simple structure, easy manufacturing and installatio...
