Common welding positioner rotary support machine types and selection principles

First, the common types of welding positioner

The basic forms of rotary support machine include leg type, tilt and flip type and double column and single flip type.

(1) The main development feature of the welding positioner is that the electric vehicle working device at one end of the column is rotated in a direction that can be rotated and rotated, and the other end is driven by the active end. Both sides of the column can be designed up and down to meet the welding requirements of different specifications of product structural parts. The disadvantage of this type of welding positioner is that it can only be rotated in a circular direction, so pay attention to whether the welding form is suitable for this choice.

(2) Double seat head and tail double rotation double seat head and tail double rotation welding structural positioner is the activity development space of welding material structural parts, adding a rotation degree of freedom single circle welding positioner on the basis of double columns. This form of welding positioner rotary support machine is more advanced, welding space is large, and the workpiece can be rotated to the required position. It has been successfully applied to many construction machinery manufacturers.

(3) L-type double rotation transformation The working device of the rotary support machine of the welding positioner is L-type, with two rotational degrees of freedom, both directions can be rotated at any Angle of ±360°. The advantages of this welding positioner are good openness and convenient operation.

(4) The C-type double rotation C-type double rotation welding positioner is the same as the L-type double rotation welding positioner, but the fixture of the welding positioner changes slightly according to the shape of the structural part. This type of welding structure positioner is suitable for the welding of loader, excavator bucket and other structural parts in China.

Second, the selection principle of the locator

The selection principle of welding positioner has three points: one is the principle of workpiece application, the second is the principle of welding convenience, and the third is the principle of easy operation.

(1) The principle of workpiece application The shape of different structural parts of construction machinery is very different, and the displacement requirements of welding are also different. Therefore, the suitable welding positioner rotary support machine should be selected according to the structural development characteristics and welding technical requirements of the welded material structural parts.

(2) Convenient for welding common welding positioner rotary support machine types and selection principles

(1) The main development feature of the welding positioner is that the electric vehicle working device at one end of the column is rotated in a direction that can be rotated and rotated, and the other end is driven by the active end. Both sides of the column can be designed up and down to meet the welding requirements of different specifications of product structural parts. The disadvantage of this type of welding positioner is that it can only work in a circular direction according to its own manual welding technology operating environmental conditions, the selected welding positioner should be able to transfer any weld of the workpiece to be welded to the flat welding or boat welding position, avoid vertical welding and upward welding, and ensure the quality of enterprise welding products.

(3) The principle of simple and convenient operation should choose a safe and reliable work, good openness, low operating system height, and compact structural design of the welding positioner, which is easy for enterprise workers to operate and place the welding positioner. If the height of the welding operation of the welding structure positioner is high, the worker can perform the welding by the pad, or by equipping the hydraulic lifting platform to adjust the height position.
