Problems solved by technology

[0005] One of the technical problems to be solved by the present invention is that the commonly used optical path sealing element in the prior art is an elastic bellows, which has a poor sealing effect and a short life, especially the expansion ratio is small, generally less than 1.5, which cannot meet the requirements of moving elements in the optical path. The problem is to provide a new installation method of the telescopic tube dust-proof mechanism with an air filter device. The telescopic tube dust-proof mechanism of this method has the advantages of long life, good sealing effect, convenient installation and strong adaptability

Abstract

The invention relates to an installing method of an extension tube dust prevention mechanism with an air filtration device, which is used for mainly solving the technical problems that in the prior art, an elastic corrugated pipe is adopted as a light path sealing element, a sealing effect is poorer, service life is short, and especially a magnification ratio is small and is usually less than 1.5, so a moving element cannot exist in a light path. The dust prevention mechanism comprises extension tubes (1), an extension tube seat (2) and a separating blocking board (3), wherein the extension tubes (1) are fixed on the extension tube seat (2); the blocking board (3) is fixed on the shaft shoulder of one extension tube; open pores (4) are formed in the extension tubes (1); and the open pores (4) are sealed though filter screens. Through the technical scheme, the problems are well solved. The installing method of the extension tube dust prevention mechanism with the air filtration device can be used in the light path of a laser machining device, and particularly suitable for the light path which is provided with a moving optical element and needs a dust prevention element with a larger magnification ratio.

Description

[0001] technical field [0002] The invention relates to an installation method of a telescoping tube dust-proof mechanism with an air filter device, which is especially suitable for the optical path with optical moving parts on high-precision laser processing equipment. Background technique [0003] In the process of high-precision laser processing, the gasification or melting of the processed materials will generate dust. Although the laser processing equipment has a dust removal mechanism, a small amount of dust still enters the optical path, which accumulates over time, causing energy loss and processing quality. In severe cases, the optical path components and even the laser will be burned out. Therefore, the optical path is often closed. In the past, the commonly used optical path sealing element is elastic bellows, which has poor sealing effect and short life, especially the expansion ratio is small, generally less than 1.5, which cannot meet the situation where ther...
