Coordinates platform for accurately locating three-dimensional laser cutting part

Abstract

The invention discloses a coordinate platform for accurately positioning three-dimensional laser cut parts, which aims to provide a coordinate platform which is convenient and fast, not only accurately and quickly positions three-dimensional laser cut parts, but also does not need the re-positioning in the repeated cutting, so that the parts can be repeatedly and accurately positioned under the machine coordinate system a plurality of times, and the positioning, programming and cutting work for laser cutting can be conveniently performed. The coordinate platform also comprises a positioning bottom plate, of which the shape is similar to that of the operating platform of the laser cutting machine, and a clip plate for positioning the cut parts. The positioning bottom plate is provided with a rectangular coordinate grid with isometric arrangement; meeting points of the coordinate grid are provided with positioning screw holes; clip plate connectors provided with cross clipping grooves are fixed on the positioning screw holes by fastening bolts; according to the shapes of the cut parts, the clip plate connectors are movably distributed on the meeting points of the coordinate grid, and the clip plate is fixed on the positioning bottom plate by the cross clipping grooves of the clip plate connectors so as to fix and support cut parts.

Description

technical field [0001] The present invention relates to a device for positioning three-dimensional laser cutting parts on a laser cutting machine tool. More specifically, the present invention is a coordinate platform device for precisely positioning laser cutting parts based on the coordinate system of the TDLC-04R laser cutting machine tool. Background technique [0002] At present, the positioning device for laser cutting three-dimensional parts with a laser cutting machine, especially for cutting automobile loading parts, usually has two positioning methods for fixing the parts. One is to select a long sheet of cuttable material according to the spatial geometry of the cutting part, weld it into a plane frame, and then select the positioning point of the part on the strip of the plane frame, and weld the vertical column of the plane frame, the column Distributed on the above planar frame. Then the parts to be cut are fixedly supported on the above-mentioned planar frame...

AI Technical Summary

Problems solved by technology

[0003] The above method of positioning and fixing the parts is often affected by the deformation of the parts, and after each positioning, the coordinate system must be adjusted again according to the cut parts. This process often takes a lot of time and is repeated many times.

Moreover, the parts cut out by these two positioning methods will produce relatively large deviations, and satisfactory results cannot be obtained.

When cutting different parts, it is necessary to repeat the positioning process; even if the same part is installed on the machine tool twice, it is time-consuming and laborious to repeat the process of coordinate fitting through feature points

It makes it difficult to accurately locate the part in the machine tool coordinate system, and generate a laser cutting program that can be used directly

How to overcome the above inefficient positioning methods and find a method that can achieve fast and accurate positioning of parts, and at the same time, do not need to reposition during repeated cutting has become an urgent problem in the industry.
