3D printing laser cutting device with protective cover

Abstract

The invention discloses a 3D printing laser cutting device with a protective cover. Support legs are mounted on the lower surface of a machine body. The upper surfaces of the support legs are connected with the lower surface of the machine body. A workbench is mounted on the upper surface of the machine body. The lower surface of the workbench is connected with the upper surface of the machine body. A base is mounted on the upper surface of the workbench. According to the 3D printing laser cutting device with the protective cover, through the cooperation among a motor, a runner and a belt andthe cooperation between a duct and a fan, droplets generated during rotary cutting of a cutting head is sucked into a collection box by the fan, so that the defects that a connecting structure of a protective cover of a traditional laser cutting device with the protective cover and a cross bar is not stable, and the protective cover is easily detached in the working process; and a laser head is not provided with a limiting device, and consequently the laser head collides with the protective cover when moving left and right on the cross bar and damage to the laser head is caused are overcome; and the production time is saved, the machining efficiency is improved, and the 3D printing laser cutting device is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a 3D printing laser cutting device with a protective cover. Background technique [0002] The so-called laser cutting is the energy released when the laser beam is irradiated on the surface of the workpiece to melt and evaporate the workpiece, so as to achieve the purpose of cutting and engraving. Smooth, low processing cost and other characteristics, the laser cutting device on the currently commonly used laser cutting machine does not have a protective cover, because the laser light source is invisible, the operator is easy to be burned and burned without knowing it, and there is no guarantee Operator safety, in the prior art, for example, the utility model patent application number 201320126895.4 includes a laser cutting device installed on a laser cutting machine, the laser cutting device includes several laser heads and cross bars, and the several laser heads s...

[0002] The so-called laser cutting is the energy released when the laser beam is irradiated on the surface of the workpiece to melt and evaporate the workpiece, so as to achieve the purpose of cutting and engraving. Smooth, low processing cost and other characteristics, the laser cutting device on the currently commonly used laser cutting machine does not have a protective cover, because the laser light source is invisible, the operator is easy to be burned and burned without knowing it, and there is no guarantee Operator safety, in the prior art, for example, the utility model patent application number 201320126895.4 includes a laser cutting device installed on a laser cutting machine, the laser cutting device includes several laser heads and cross bars, and the several laser heads slide Set on the crossbar, the two ends of the crossbar are slidably embedded on the guide rails on both sides of the laser cutting machine, and a protective cover is provided on the outside of the laser cutting device, and the two ends of the protective cover are fixed on the two sides of the crossbar. The protective cover is square, and one side of the protective cover is opened, and the protective cover is made of stainless steel. Although the utility model has a simple structure, there are many deficiencies and defects. In the existing equipment, the design of the protective cover There are defects, the connection structure between the protective cover and the cross bar is unstable, the protective cover is easy to fall off during the work process, and the laser head is not equipped with a limit device, which causes the laser head to collide with the protective cover when it moves left and right on the cross bar, causing the laser head to fall off. In view of these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a 3D printing laser cutting device with a protective cover to overcome the defects in the prior art
