Protective device for industrial welding robot

Abstract

The invention discloses a protective device for an industrial welding robot. The protective device comprises a welding head body, a welding rod, a protective cover, a connecting pipe, a connecting disc, a reset spring, a piston rod, an air cylinder, a fixed plate, a guide plate, a first through hole, a second through hole, a guide groove, a smoke suction box, a limiting plate and a smoke suction hole. The protective cover can be slidably connected with the welding head body through the guide groove in the lateral side of the connecting disc. During use of the welding head body, the protectivecover can slide along the guide plate when touching a welding piece, the reset spring can enable the protective cover to extend and contract, and the normal use of the welding head body is guaranteed.The piston rod is driven to move through the air cylinder. Because the limiting plate is clamped in the protective cover, the protective cover can move along with the piston rod, and a connecting position between the welding head body and the welding rod can be exposed so as to facilitate replacement by workers. Because the smoke suction box is arranged in the protective cover, smoke generated during welding can be pumped away by externally connecting smoke suction equipment with the connecting pipe, and human bodies are prevented from being damaged.

Description

technical field [0001] The invention relates to a protective device, in particular to a protective device for an industrial welding robot, which belongs to the technical field of industrial robot applications. Background technique [0002] A welding robot is an industrial robot engaged in welding (including cutting and spraying). According to the definition of a standard welding robot by the International Organization for Standardization, an industrial robot is a multipurpose, reprogrammable automatic control operation machine with three or More programmable axes are used in the field of industrial automation; in order to adapt to different purposes, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be connected to different tools or end effectors. Welding robots are used in industrial The end shaft flange of the robot is equipped with welding tongs or a welding (cutting) torch, enabling it to perform welding, cutting or thermal...

AI Technical Summary

Problems solved by technology

[0003] With the development of industry, welding robots are also widely used in industrial production. The existing industrial welding robots lack protective devices at the welding head when they are in use. Personnel bring safety hazards, and there will be smoke generated during the welding process, the smell is more pungent, and long-term exposure to this environment will have an impact on the body
