Cross beam structure for large-format optical fiber laser cutting machine

Abstract

The invention relates to a cross beam structure for a large-format optical fiber laser cutting machine. A Z axis is arranged on a cross beam rolling linear guide rail; two ends of a cross beam are arranged on a left cross beam movement sliding seat and a right cross beam movement sliding seat; the left cross beam movement sliding seat and the right cross beam movement sliding seat are arranged ona base rolling linear guide rail; a motor is connected with a speed reducer; a gear is connected with the speed reducer; a rack meshes with the gear and is arranged on a lathe bed; the lathe bed is fixed onto a base; the motor drives the left cross beam movement sliding seat and the right cross beam movement sliding seat to move on the rack by adopting the base rolling linear guide rail as an X-axis direction; and automatic floating adjustment systems are arranged in the left cross beam movement sliding seat and the right cross beam movement sliding seat. According to the cross beam structurefor the large-format optical fiber laser cutting machine provided by the invention, the optical fiber laser cutting machine is long in runnable stroke, stable to run, high in positioning accuracy, high in repositioning accuracy, high in runnable speed acceleration, high in other parameters, convenient to adjust, and capable of realizing high-accuracy cutting without manual intervention in the whole process.

Description

technical field [0001] The invention relates to an optical fiber laser cutting, in particular to a beam structure for a large-format optical fiber laser cutting machine. Background technique [0002] Laser cutting machines are used more and more in industry. Because the laser cutting machine has many characteristics such as fast processing speed, good processing quality, simple operation, strong applicability of processing plates and graphics, and convenient replacement of processed parts, it has been widely used in automobiles, rolling stock manufacturing, aviation, chemical industry, light industry, Industrial sectors such as electrical appliances and electronics, petroleum and metallurgy. However, in order to meet the needs of the market in various aspects, various requirements have been put forward for laser cutting machines in order to better meet the market needs. The application of laser cutting can be promoted in the following aspects: [0003] (1) With the develo...

Problems solved by technology

[0009] (7) For the market, the thickness of the cut plate is getting thicker and thicker, and the width of the processed plate is getting longer and wider. Many do not want to cut and then process, which leads to high precision requirements.

However, domestic machine tools cannot process the base as a whole, and must be processed in sections, so there will be a certain slight change in straightness and parallelism in the X-axis direction, which will lead to a decrease in cutting accuracy.
