Abstract

The invention discloses a focusing lens protecting device for a laser cutting machine and relates to the technical field of laser cutting machines. The focusing lens protecting device comprises a mounting base, wherein the mounting base is provided with a lens protecting mechanism through a slot; the upper surface of the mounting base is in sliding fit with a rotating ring through an annular sliding chute; one side of the mounting base is provided with a T-shaped groove; the T-shaped groove is in sliding fit with a T-shaped strip; a laminate is fixedly connected to the upper surface of the mounting base; a plurality of sector plates are rotationally connected to the upper surface of the laminate; and a cover plate is fixedly connected to the upper surface of the laminate. According to thefocusing lens protecting device disclosed by the invention, a rack on the mounting base is utilized to drive a gear ring to rotate and realize opening and closing between the sector plates; the effectof isolating a focusing lens is achieved, the protecting effect of the focusing lens is improved, and service life of the focusing lens is effectively prolonged; and meanwhile, the position of the rack is controlled by using an adjusting screw on the lens protecting mechanism, and the operations of changing protective lenses and opening and closing the sector plates are synchronously finished, and thereby the use convenience of the protecting device is improved.

Description

Technical field [0001] The invention belongs to the technical field of laser cutting machines, and particularly relates to a focusing lens protection device of a laser cutting machine. Background technique [0002] The existing laser cutting machine is equipped with a protective lens to protect the focusing lens to prevent dust or anti-slag from sticking to the focusing lens and causing the lens to burn; the protective lens assembly is installed in the cavity of the protective lens cavity, It is inserted and fixed in the protective lens cavity from the front. [0003] However, when the protective lens is removed and replaced, the protective lens cavity is connected to the outside, leaving the inside exposed, so that the focusing lens is in an unprotected state. Dust in the air can easily enter the protective lens cavity, thereby polluting the focusing lens. , Affecting the focusing effect and the service life of the focusing lens, [0004] Therefore, it is urgent to design a protec...
