(1) Select the appropriate welding positioner according to the structural characteristics of the welding equipment. For example, the rear frame and roller frame of the loader are double-column single rotation, the front frame of the loader can be designed as L-type double rotation, the loader bucket welding positioner can be designed as C-type double rotation, and the excavator frame and bucket The rod can choose double-seat head and tail double rotation, and some small parts welding parts can choose the series of seat-type welding positioners produced on the market.
(2) According to manual operation, the selected welding displacement function moves any welding of the weldment to the flat welding or ship welding position to avoid vertical and overhead welding and ensure the welding quality.
(3) Choose a welding positioner with good openness, easy operation, and small footprint. The operating height of workers should be as low as possible for safety. The tooling design needs to consider the simplicity and convenience of work card installation. This point should also be improved when selecting, so as not to affect the later use effect and comfort of the welding auxiliary machine.
(4) The welding height of the positioner for large-scale welding components of engineering machinery is high, and workers can weld on the gasket. The selection of welding climbing section directly affects the use of welding positioner. The small fixed climbing section can use three-dimensional or two-dimensional mechanical and electronic control to automatically move the welding lifting platform according to the height.
