Abstract

The invention discloses a method and a device for quickly determining the defocusing amount in the technical field of laser machining. The device comprises a laser head, a laser head clamping part is clamped at the lower part of the left side of the outer wall of the laser head, four groups of clamping part positioning screws are distributed rectangularly on the periphery of each of the front surface and the rear surface of the laser head clamping part, a measurement ruler clamping part is arranged in the middle of the left side of the laser head clamping part, a measurement ruler is perpendicularly inserted into an inner cavity of the measurement ruler clamping part, measurement ruler positioning screws are arranged on the surface of the measurement ruler clamping part, a clamping part through groove is horizontally formed in the middle of the surface of the laser head clamping part, the defocusing amount can be determined rapidly, and the device is good in economy, flexible in measurement, compact in structure, high in applicability and suitable for determining the defocusing amount of different types of laser devices and complicated machining parts in narrow spaces at different angles.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a method and device for rapidly measuring defocusing amount. Background technique [0002] With the development of high-power lasers, laser processing technology is more and more widely used in industrial fields. Defocus refers to the distance between the focused spot of the laser beam and the surface of the workpiece to be processed, which is an important parameter affecting the quality of laser processing. At present, vernier calipers and height gauges are usually used for the determination of defocus, and vernier calipers are mainly used to measure CO 2 For the defocus amount of the laser head, use the measuring needle to measure the relative defocus amount, then use the vernier caliper to measure the height of the measuring needle, and calculate through the formula to determine the actual coordinates under a certain defocus amount. This method has large errors and i...
