Buffer displacement mechanism of laser cutting machine

Abstract

The invention discloses a buffer displacement mechanism of a laser cutting machine. The buffer displacement mechanism comprises a cutting machine table, wherein limiting blocks are arranged at the twoends of the upper surface of the cutting machine table, the same driving screw rod is rotatably connected between the two limiting blocks through a bearing, a transverse damping displacement block isarranged on the surface of the driving screw rod in a sleeving mode, an X-axis cutting frame is arranged on the upper surface of the transverse damping displacement block, buffer mechanisms are arranged on the upper surface of the cutting machine table and the inside of the transverse damping displacement block separately, and automatic buffer components extending to two sides of the transverse damping displacement block are arranged in the transverse damping displacement block. According to the mechanism, magnetic attraction is generated by arranging a magnetic plate and a deceleration magnet, so that the mechanism has the deceleration effect, and magnetic force is gradually increased, so that strong collision between the side surfaces of the transverse damping displacement block and thelimiting blocks is avoided; and meanwhile, the buffer mechanisms consisting of negative pressure balls are arranged, so that inflation and deflation of the negative pressure balls are driven by selfmotion, and the inflated negative pressure balls make contact with the limiting blocks, so that the mechanism has the buffering and damping effects.

Description

technical field [0001] The invention relates to the technical field of laser cutting machines, in particular to a buffer displacement mechanism of a laser cutting machine. Background technique [0002] Laser cutting is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. With the movement of the relative position of the beam and the workpiece, the material will eventually form a slit, so as to achieve the purpose of cutting. There are existing research and development and application of energy-saving technology for heating and residential buildings. [0003] During the cutting process, the laser cutting head needs to move in the X-axis and Y-axis directions according to the generated graphics....

AI Technical Summary

Problems solved by technology

In order to improve the cutting efficiency, the laser cutting head needs to move at a high speed. Among them, the moving track of the Y-axis is longer. When moving to both ends at high speed and contacting the limit block, it is easy to generate a large impact force. This impact force is easy to make the cutting head Vibration will affect the cutting progress
