A four-degree-of-freedom industrial robot for welding waste-retaining plates of sewage treatment pipelines

Abstract

The invention relates to a four-freedom-degree industrial welding robot for a sewage treatment pipeline and a feculence-blocking plate. The four-freedom-degree industrial welding robot comprises a base, a lifting device, a rotary drive device, a redundant parallel mechanism, a welding execution device and a fixing device. The lifting device is located at the rear side end of the base, the rotary drive device is located over the lifting device, the redundant parallel mechanism is located below the front end of the rotary drive device, the welding execution device is located under the redundant parallel mechanism, and the welding execution device is fixedly connected with the redundant parallel mechanism. The fixing device is symmetrically arranged on the upper end face of the base and is fixedly connected with the base. According to the industrial welding robot, the sewage treatment pipeline and the feculence-blocking plate can be subject to full-automatic intelligent welding work, during welding, the whole position is adjustable, the local position is flexible in motion, stability is high, meanwhile the function that welding wire feeding is achieved while welding is carried out is achieved, the welding efficiency is high, and the welding quality is good.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a four-degree-of-freedom industrial robot for welding trash-stop plates of sewage treatment pipelines. Background technique [0002] Welding is also known as welding or welding. Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flames, electric arcs, Laser, electron beam, friction and ultrasonic, etc., in addition to being used in factories, welding can also be carried out in a variety of environments, such as the field, underwater and space, no matter where welding may bring danger to the operator, Therefore, appropriate protective measures must be taken when welding. Possible injuries caused by welding include burns, electric shock, visual impairment, inhalation of toxic gases, and excessive ultraviol...

AI Technical Summary

Problems solved by technology

[0003] Sewage treatment pipes are mainly used in municipal engineering, chemical plants, petroleum engineering, and water supply projects. There will always be a trash plate welded in the middle of the sewage treatment pipeline. The main function of the trash plate is to block debris flowing into the sewage treatment pipeline. On the one hand, it prevents the sewage treatment pipeline from being blocked by debris; Cost, low welding efficiency, poor welding quality, and due to manual welding, dangerous accidents often occur during the welding process, which brings certain personal dangers to welders
