Introduction to the movement driving mode of the elastic arm of the welding manipulator

In the actual application process, it is found that the elastic arm of the welding manipulator is mostly at a constant speed or two speeds of fast and slow; while the lifting of the elastic arm is at two speeds of fast and slow or infinitely variable, and in general, the speed is controlled at Those between 0.5-2m/min are more.
Secondly, there are two drive modes for the reverse movement of the elastic arm of the welding manipulator, which are manual and constant speed electric. The former is more commonly used in small welding manipulators, while the latter is mostly used in large and medium-sized welding manipulators, and their reverse speed is generally 0.6r/min. Not only that, but in the reversing system of the elastic arm of the welding manipulator, there is usually a manual locking device to ensure the safety of the equipment during operation.
For the welding manipulator, whether it is a circular column or a non-circular column, the reversal of the elastic arm almost always adopts the reverse type of the column itself, so that the bottom end of the column sits on the thrust bearing directly or through the tooth circle, ensuring that the column sensitive scrolling.
In the automatic welding manipulator, the feeding movement of its elastic arm is mostly driven by a DC motor, and of course some are driven by an AC servo motor, mainly to meet the welding speed feed of the welding manipulator when welding the longitudinal seam. It has high requirements on the stability of its operation at welding speed, and the fluctuation of feed speed should be less than 5%.
Some welding manipulators are also equipped with a gear speed, which is mostly between 180-240m/h. Movement and stroke protection device.
