Laser cutting machine upper and lower laser head coaxial, lifting adjustment device and method

Abstract

The invention discloses a device and method for coaxial operation and lifting adjustment of an upper laser tool bit and a lower laser tool bit of a laser cutting machine. The upper laser tool bit, the lower laser tool bit, an extension shaft A and an extension shaft B are installed in an upper laser tool bit extension base and a lower laser tool bit extension base correspondingly. A left-right adjusting base, a front-back moving base and a spherical base are installed on the upper laser tool bit extension base. The extension shafts can be conveniently and rapidly adjusted to move front and back or left and right or to rotate at a pitching angle by adjusting a front-back adjusting screw on the front-back moving base, a left-right adjusting screw on the left-right adjusting base, and a pitching adjusting screw on the spherical base, so that the upper laser tool bit and the lower laser tool bit are coaxial. The upper laser tool bit extension base and the lower laser tool bit extension base are each provided with an extension hand wheel assembly, the extension shaft A and the extension shaft B are engaged with gears on a gear shaft, and lifting adjustment of the extension shafts, the upper laser tool bit and the lower laser tool bit is achieved. The device and method are suitable for cutting of thick materials with variable thicknesses, cost is effectively reduced, the precision and appearance quality of machined pieces are ensured, the application range is wide, and popularization is easy.

Description

technical field [0001] The invention belongs to the technical field of laser cutting processing, and relates to the use of laser cutting to process various metal and non-metallic plates, and double-headed laser cutting to process circular templates with variable diameters. Specifically, it relates to a laser cutting machine with upper and lower laser cutter heads coaxial Lifting adjustment device and method. Background technique [0002] At present, it is feasible for the dual-laser head laser cutting machine to be used for various types of plate cutting, especially for template cutting in the die-cutting plate manufacturing industry. The double-head laser cutting machine uses two low-power lasers to cut and process the plate simultaneously and synchronously. Instead of a single laser head laser cutting machine, a high-power laser is used to cut and process a certain thickness of the plate in one direction, making laser cutting equipment manufacturing And the cost of use is...

AI Technical Summary

Problems solved by technology

[0004] The double-head laser cutting machine cuts the plate in both directions simultaneously and synchronously with the upper and lower laser cutter heads. There is a problem that the upper and lower laser cutter heads need to be precisely coaxial, that is, the upper and lower laser cutter heads need to be adjusted on the center line of the workpiece without misalignment. Only in this way can the processed round template be cut through to achieve the required precision and appearance quality. Therefore, the coaxial degree of the upper and lower double laser cutter heads, and the coaxial design and adjustment device for the upper and lower laser cutter heads directly affect the quality of the processed round template.
