Laser cutting mechanism

Abstract

The invention relates to a laser cutting mechanism. The laser cutting mechanism comprises a lower frame and an upper frame. The lower frame is provided with bearing devices matched with a product. Theupper frame is provided with a laser cutting device. The laser cutting device comprises a cutting sleeve connected with the upper frame through connecting rods. The cutting sleeve is a cavity sleevewith an opening on the lower portion. The lower portion of the upper frame is provided with a cutting lifting cylinder of which the cylinder head penetrates into a cavity of the cutting sleeve. The lower portion of the cutting lifting cylinder is connected with a cutting lifting block. The lower portion of the cutting lifting block is connected with a laser cutter capable of feeding. The inner wall of the cutting sleeve is provided with a touch induction screen. Cutting lifting balls being tangential to and matched with the touch induction screen are embedded on the side face of the cutting lifting block. The laser cutting mechanism provided by the invention can ensure that a laser emitting head can keep in a vertical state all the time in the lifting process and then can ensure the good laser cutting effect.

Description

technical field [0001] The invention relates to the field of laser applications, in particular to a laser cutting mechanism. Background technique [0002] Laser cutting uses a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly and reach the boiling point of the material in a very short period of time. The material begins to vaporize and form steam. The steam is ejected at a high speed. Simultaneously, an incision is made in the material. [0003] Such as figure 1 The main body of product 4 is composed of plates with two downward notches. Sometimes, product 4 needs to be cut from it, so a cutting device is needed, usually a laser cutting device is used. Due to the Thickness problem, when laser cutting, the distance between the laser emitting head and the plate is not the same, so it is necessary to adjust the height. Most of the existing height adjustments use cylinders to directly lift and lower. A slight tilt occurs, which in tu...

[0003] like figure 1 The main body of product 4 is composed of plates with two downward notches. Sometimes, product 4 needs to be cut from it, so a cutting device is needed, usually a laser cutting device is used. Due to the Thickness problem, when laser cutting, the distance between the laser emitting head and the plate is not the same, so it is necessary to adjust the height. Most of the existing height adjustments use cylinders to directly lift and lower. Slight tilt occurs, which will affect the quality of the cut
