Description

technical field [0001] The invention relates to the field of laser cutting and drilling, in particular to a device for laser rotary cutting and processing oblique holes. Background technique [0002] Generally, in order to achieve the effect of energy saving and emission reduction, internal combustion engines need to use smaller fuel injection holes. The diameter of the fuel injection hole that meets the Euro III emission regulations is Φ0.14-0.17mm, and the size of the higher standard fuel injection hole requires a smaller size. , At the same time, in order to fully burn the fuel, it is necessary to obtain a better fuel injection atomization effect, so the fuel injection hole of the fuel injector is usually designed as a plurality of oblique holes. [0003] The traditional small hole processing technology includes mechanical drilling, electric spark drilling and electro-hydraulic beam, etc. These traditional processing technologies have their own shortcomings. The drill bit...

Problems solved by technology

[0003] The traditional small hole processing technology includes mechanical drilling, electric spark drilling and electro-hydraulic beam, etc. These traditional processing technologies have their own shortcomings. The drill bit is easy to break when mechanical drilling is used to process fine inclined holes; the diameter of EDM drilling is less than 300μm. The micro-holes have always had problems such as low efficiency and can only process metals with good electrical conductivity; the efficiency of electro-hydraulic beam machining is low, and the shape accuracy of the holes is not good, the dimensional accuracy is uncontrollable, and the processing taper is uncontrollable
