Rotary cutting and punching device based on dove prism

Abstract

The invention belongs to the technical field of laser processing, and particularly provides a rotary cutting and punching device based on a dove prism. The rotary cutting and punching device comprisesa supporting plate capable of moving horizontally as a whole, a reflecting mirror, a set of optical wedges arranged in a complementary mode, the dove prism and a focusing lens, wherein the reflectingmirror, the optical wedges, the dove prism and the focusing lens are sequentially arranged in the direction of an optical path. The reflecting mirror and the optical wedge set are fixedly installed on the supporting plate. The dove prism is arranged in a rotatable hollow motor. A processing material is located on the focus of the focusing lens. According to the scheme, the number of adjusting devices is small, the installation steps are simple, and the adjusting steps are relatively simple. Holes with different apertures and different tapers can be punched by simply adjusting the rotating angles of the optical wedges and the overall position of the supporting plate without replacing the devices, and therefore the processing cost is greatly reduced. By means of the dove prism, the efficiency of the rotation of laser beams when the hollow motor works can be improved, the punching efficiency can be doubled compared with other methods, and the overall efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a rotary cutting and drilling device based on a Dove prism. Background technique [0002] Laser drilling is the earliest practical laser processing technology, and it is also one of the main application fields of laser processing. Laser drilling processing technology is widely used in many industrial processing technologies, mainly used in aerospace, automobile manufacturing, electronic instruments, etc. industry. How to solve the aperture size required for processing round holes, aperture taper and roundness are the main issues that need to be considered in laser drilling. The traditional drilling process is mainly drill drilling and EDM drilling. The drilling accuracy of the drill bit is low, and the change of the hole diameter cannot be changed in time. It is suitable for holes with a diameter of more than 2mm, and the drill bit is easy to break, and the ...

Problems solved by technology

The traditional drilling process is mainly drill drilling and EDM drilling. The drilling accuracy of the drill bit is low, and the change of the hole diameter cannot be changed in time. It is suitable for holes with a diameter of more than 2mm, and the drill bit is easy to break, and the yield rate is low. Low-level problems, but there are problems such as instability and high energy consumption in EDM drilling, and the processing speed is very slow. The holes punched by this method will have burnt edges and taper problems.
