Exchange table of fiber laser cutting machine

Abstract

The invention discloses an exchange table of a fiber laser cutting machine. The exchange table comprises a driving module, a worktable and a laser module, all of which are arranged on a main bed body. The driving module comprises a driving motor and a driving chain which are arranged on one side of the main bed body. The driving chain is divided into an upper chain body and a lower chain body with a left gear and a right gear as the end points. The worktable is divided into an upper worktable body and a lower worktable body in a left-right staggered manner. An upper sliding supporting frame is arranged below the lower worktable body. The upper sliding supporting frame is connected into a first chain joint of the lower chain body through a first right-angle connecting piece and is fixed. Upper limiting pulleys are arranged on one side of the lower worktable body. An oblique guide rail is arranged at the position, corresponding to the part below a sliding wheel of the lower worktable body, of the upper sliding supporting frame. According to the exchange table of the fiber laser cutting machine, the oblique guide rail is adopted to be matched with a purely-mechanical structure of the sliding wheel in the exchange process, the problem that pressure releasing and control are not stable in traditional hydraulic exchange is solved, higher stability and the lower failure rate are provided, cost is low, and maintenance is convenient.

Description

technical field [0001] The invention relates to the field of laser cutting machines, in particular to an exchange table of an optical fiber laser cutting machine. Background technique [0002] In the machinery industry, thin metal sheets, stainless steel sheets, aluminum sheets, carbon steel sheets, traditional flame cutting, and plasma cutting are often cut, making products prone to burrs, and there are certain technical defects in processing accuracy and cutting quality. Fiber laser is a new type of fiber laser newly developed in the world. It outputs high-energy-density laser beams and gathers them on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and gasified, and the spot is moved by the numerical control mechanical system. Automatic cutting is realized by irradiating the position, with high speed and high precision. For this reason, the present invention provides an optical fiber laser cuttin...

AI Technical Summary

Problems solved by technology

[0003] The optical fiber laser processing equipment in the prior art generally only has one laser cutting area, that is, after cutting the corresponding incoming workpiece, it is necessary to unload the processed workpiece, and then load a new incoming workpiece to continue cutting, so First, even if the processing work is interrupted at intervals, the work continuity is poor, the production speed is slow, the production efficiency is low, and the processing cycle is long, which also makes various costs higher.

There are also some optical fiber laser processing equipment that exchange worktables for laser cutting. This kind of optical fiber laser processing equipment uses hydraulic pressure for lifting and lowering during the exchange process. The hydraulic drive has the risk of pressure release, and the use is unstable. low
