Several basic forms of commonly used welding positioners

The basic forms of commonly used manual welding positioners include outrigger type, flip-rotation type, double-column single-turn type, etc. Due to the limited rotational freedom, these positioners cannot realize arbitrary rotation of the workpiece to be welded in space, and cannot rotate each weld seam to the desired optimal position. The following introduces the selection of welding positioners and several commonly used forms of positioners.

1. The significance of using welding positioners for construction machinery structural parts

Most of the structural components of construction machinery such as bulldozers, excavators, and road rollers are very complex and are the main factors of the entire machine. The quality of their welding directly affects the performance of the entire machine. Choosing the appropriate welding displacement function improves welding quality and production efficiency, reduces worker labor intensity and production costs, strengthens safe and civilized production, and is conducive to on-site management.

2. Selection of structural parts welding positioner

1. Select the appropriate positioner according to the characteristics of the welded structural parts. For example, the bulldozer's rear axle housing and the excavator's It can be designed as a C-shaped double-turn type, and the excavator's boom can be designed as a 2-column single-turn type.

2. The welding displacement function selected according to the manual welding operation conditions can move any weld seam in the welded workpiece to the flat welding or shipboard welding position, avoiding vertical welding and back-to-back welding, and ensuring the welding quality.

3. According to the operation needs, select a positioner with good openness, easy operation, compact structure and small floor space. The operating height of the operator should be as low as possible, which is safe and reliable. Please consider the workpiece chuck to be simple and convenient when designing.

4. Selection of large structural parts Construction machinery The positioner of large welding structural parts has a high welding height, and the operator can perform welding by increasing the height. Equipped with a hydraulic lifting platform, welding can also be carried out at different heights conveniently.
