Automatic mechanical arm for welding

Abstract

The invention relates to an industrial welding robot, in particular to an automatic mechanical arm for welding. The automatic mechanical arm comprises a base, a mechanical arm body and a welding gun. The mechanical arm body is composed of two rigid rod bodies, the first rigid rod body is fixedly connected to the base, the second rigid rod body is in series connection with the first rigid rod body through a rotary joint and can freely move, the tail end of each rigid rod body is connected with a wrist, the wrists are connected with the welding gun, and the inside of the base is provided with a PLC controller. The automatic mechanical arm has the advantages that quality of a welded product is stabilized and improved through mechanical welding, welding uniformity of the product is guaranteed, productivity is improved, 24-hour continuous production can be achieved, work conditions of workers are improved, the automatic mechanical arm can work in a harmful environment for a long time, operations are simple and convenient to carry out, professional staff are needless, requirements for operation techniques of the workers are reduced, and welding automation of small-batch products can be achieved.

Description

technical field [0001] The invention relates to an industrial welding robot, in particular to an automatic welding mechanical arm. Background technique [0002] For the automatic welding water tray faucet device with application number 201210140887.5, a device for fixing and rotating the welding parts through welding points is provided. The mobile welding torch provides greater convenience for manual welding nozzles, but traditional manual welding is prone to false welding, low production efficiency, poor product quality, and the staff are prone to fatigue when welding for a long time. At the same time, the toxic gas generated during welding It also has a great impact on the health of the staff. Contents of the invention [0003] In order to solve the above problems, the present invention provides an automatic welding robot arm. [0004] The technical scheme adopted in the present invention is as follows: an automatic welding mechanical arm, comprising: a base, a mechani...
