Problems solved by technology

[0003] Among them, the laser cutting machine has the fastest efficiency, the highest cutting precision, and the cutting thickness is generally small. However, when the existing laser cutting machine cuts the workpiece, the workpiece often The fixation is not stable, resulting in errors in the cutting size, which in turn affects the quality of the cut workpiece; at the same time, in order to prevent the high temperature generated during the cutting process from sticking the workpiece and the platform together, most of the existing workpiece positioning mechanisms for laser cutting use two sets of The clamping mechanism clamps and fixes both ends of the workpiece and lifts it up for cutting. During the laser cutting process, due to the lack of corresponding auxiliary support structures, the laser cutting part falls under gravity, resulting in deformation of the workpiece and affecting the quality of the cut workpiece.

Abstract

The invention discloses a workpiece positioning mechanism of a laser cutting machine, and relates to the technical field of laser processing. The clamping device comprises two sets of clamping assemblies which are oppositely arranged. The clamping frame is symmetrically matched with clamping plates in a sliding manner; the mounting frame is in sliding fit with a transmission assembly; the mounting hole is in sliding fit with the sliding rod; a rotating shaft at one end of the driving roller penetrates through the mounting table and is fixedly connected with a rotating gear; the two sliding channels are in sliding fit with sliding pieces. And the upper gear rack and the lower gear rack are respectively meshed and matched with the two rotating gears. A workpiece is clamped and fixed through the clamping plates on the two clamping frames, and the servo motor is started to drive the lead screw to rotate, so that the transmission assembly is driven to slide, the to-be-cut position is located between the two mounting tables, and the workpiece is positioned and supported; and after cutting is completed, clamping and fixing of the clamping plate are relieved, the sliding piece is pulled, the two rotating gears are driven to synchronously and reversely rotate, and therefore the two sets of driving rollers are driven to synchronously and reversely rotate, and the cut workpieces are synchronously and reversely conveyed out of the corresponding mounting tables.

Description

technical field [0001] The invention belongs to the technical field of laser processing equipment, in particular to a workpiece positioning mechanism of a laser cutting machine. Background technique [0002] With the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. The development of CNC cutting machine must meet the requirements of the development of modern mechanical processing industry. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water cutting machines, etc. [0003] Among them, the laser cutting machine has the fastest efficiency, the highest cutting accuracy, and the cutting thickness is generally small. However, when the existing laser cutting machine cuts the work...
