The utility model relates to the technical field of welding operation equipment, in particular to a welding clamping turning and shifting machine.

Background technique

The welding positioner is a device used to drag the workpiece to be welded, so that the welding seam to be welded moves to the ideal position for welding operation.

In the eyes of people, the positioner may be considered a trivial product. However, internationally, there are more than 100 series including products with various functions. Technically, there are ordinary types; there are gapless transmission servo control types; the rated load range of the product reaches 0.1kN to 18000kN. It can be said that the positioner is a product with many varieties, low technical level and complete development of small, medium and large.

However, the welding positioner is a young product. Due to the difference in the development level between the manufacturing industries, the welding stations of many enterprises are not equipped with positioners; at the same time, the related research is relatively weak. The maximum inclination angle of the existing positioner is only 135°, and when the workpiece bottom plate of the positioner is connected to its transmission part, welding cannot be performed from the bottom of the bottom plate.
