Description

technical field [0001] The invention belongs to the technical field of movable robots, and in particular relates to a movable ultrafast laser processing robot equipment and a processing method. Background technique [0002] As my country's manufacturing of major structural parts develops in the direction of large size, light weight, high load capacity, and high reliability, its high-precision, high-flexibility manufacturing features pose new challenges to processing equipment. With the outstanding advantages of non-metallic composite materials such as resin-based composite materials, ceramic-based composite materials, and carbon-based composite materials, due to their outstanding advantages such as light weight and high strength, wide temperature range, low expansion, good fatigue resistance, and excellent heat resistance, they have begun to receive more and more attention. more and more widely used. [0003] Although non-metallic composites are primarily manufactured using...

Problems solved by technology

[0004] The first is the problem of machinable size: due to the limitation of the stroke of CNC machining equipment and the size of the workpiece that can be accommodated, it is difficult to process large-scale structures (such as the central load-bearing cylinder, the arm of the large-scale antenna deployment arm);

[0005] The second is the problem of efficiency and cost: high strength and high hardness of materials lead to low processing efficiency, low tool durability, frequent tool changes, high processing costs, and low processing efficiency. At present, a large number of composite material structure holes still use manual hole making;

[0006] Finally, there are precision and quality issues: the anisotropy and heterogeneity of materials lead to delamination or chipping, fiber breaking or pulling out, microcracks, surface roughness and other outstanding processing quality defects, which affect the mechanical properties of the structure

Using traditional laser sources (such as carbon dioxide laser, millisecond / microsecond / nanosecond laser) to process non-metallic composite material structures, although it can avoid the separation caused by the existence of contact stress in traditional contact processing (such as cutting processing, ultrasonic vibration-assisted cutting processing). However, due to the outstanding thermal effect of traditional laser sources, there is a prominent processing heat-affected zone on the edge of the processed structure, carbonization or discoloration of the surface of the processed area, and low structural dimensional accuracy. question

The processing precision of the structure is low and the accuracy consistency is poor, which cannot meet the preparation of higher precision structures such as functional windows and fine holes for installation and calling.
