Eight-shaft mechanism for robot three-dimensional laser cutting device of car body sheet metal part

Abstract

The invention discloses an eight-shaft mechanism for a robot three-dimensional laser cutting device of a car body sheet metal part. The eight-shaft mechanism comprises an industrial six-shaft robot, alaser machining head, a fixture mechanism, a sliding mechanism, a turning-over mechanism and a periphery wall. The industrial six-shaft robot, the laser machining head, the fixture mechanism, the sliding mechanism and the turning-over mechanism are all located in the periphery wall. The laser machining head is installed on a rotary table of a sixth shaft of the industrial six-shaft robot, the fixture mechanism is located above the turning-over mechanism, and the turning-over mechanism is located on the sliding mechanism. The eight-shaft mechanism has the beneficial effects of being simple instructure and high in practicability.

Description

technical field [0001] The invention relates to the field of automobile sheet metal processing, in particular to an eight-axis mechanism of a robot three-dimensional laser cutting device for automobile body sheet metal parts. Background technique [0002] Laser cutting is the most important application technology in the laser processing industry. Due to its many characteristics, it has been widely used in industrial sectors such as automobiles, rolling stock manufacturing, aviation, chemical industry, light work, electrical appliances and electronics, petroleum and metallurgy. Compared with other cutting methods, laser cutting has the characteristics of high speed, high precision and high adaptability. At the same time, it also has the advantages of fine kerf, small heat-affected zone, good cutting surface quality, no noise during cutting, good verticality of kerf edge, smooth cutting edge, and easy automatic control of the cutting process. Many of the sheet metal parts of ...

AI Technical Summary

Problems solved by technology

Many of the sheet metal parts of the automobile body require laser cutting to complete the cutting of the profile and the cutting of the hole. Increased difficulty in forming and trimming

The operation and cost of molds and traditional cutting equipment have great limitations. Often a complex surface requires several sequences of molds to complete, which increases the production cycle and wastes costs.

Traditional planar laser cutting equipment is aimed at cutting two-dimensional planes, and cannot perform high-precision cutting on three-dimensional curved surface parts. Some large-scale three-dimensional laser cutting equipment needs to be imported from abroad. The equipment is expensive and the cutting range is very limited.
