Force Control Grinding Tool for Laser Weld Grinding

Abstract

The invention discloses a force-control polishing tool for laser weld joint polishing. The force-control polishing tool comprises an installation assembly, a flexible flange and an electric main shaft; and the installation assembly is a force-control polishing tool for achieving laser weld joint polishing and connected with at least one robot, and meanwhile interference of robot movement is avoided, and the electric main shaft and the flexible flange are perpendicularly installed. According to the force-control polishing tool for laser weld joint polishing, automation and intellectualization of polishing are achieved, a sleeve shell with a hair brush is brought in, the dedusting problem of the device can be well solved, the man-made machine-stopping accident caused due to manual replacing of polishing tools and materials can be well solved, polishing efficiency is improved, and polishing automation is improved.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a force-controlled grinding tool for laser welding seam grinding. Background technique [0002] The auto body workshop has a high level of automation, a fast production cycle and high requirements for the entire grinding quality. At present, the welding of the roof and the rear of the car in the body workshop of major car companies has changed from traditional arc welding to laser welding, and the welding seam grinding has changed from manual grinding to automatic robot grinding. The traditional mechanical grinding head is difficult to control the grinding process parameters such as the grinding force and the speed of the grinding wheel, resulting in fast consumption of the grinding wheel; at the same time, the traditional mechanical grinding head cannot automatically change the tool, and needs manual tool replacement from time to time. The automation level is low and manual intervention is req...

AI Technical Summary

Problems solved by technology

The traditional mechanical grinding head is difficult to control the grinding process parameters such as the grinding force and the speed of the grinding wheel, resulting in fast consumption of the grinding wheel; at the same time, the traditional mechanical grinding head cannot automatically change the tool, and needs manual tool replacement from time to time. The automation level is low and manual intervention is required; The dust removal effect of the traditional mechanical grinding head is poor, the overall dust removal effect is about 30%, and the dust in the entire grinding station is serious; the traditional mechanical grinding head cannot perform grinding displacement compensation for the welding error of the weld seam, and it is difficult to debug the entire robot trajectory, and the grinding quality is difficult to guarantee
