Problems solved by technology

[0003] The Chinese utility model patent No. 98247370.2 discloses a U-shaped elbow girth welding positioner, which uses an open gear for transmission, and an opening is opened on the transmission gear, so that the pipe fittings to be welded are arranged on the gear In general, the welding is realized by rotating and displacing through gear transmission, but due to the limitation of the manufacturing process, the nominal diameter of the large gear has an upper limit (the maximum is not more than 1.5 meters), so when performing large-scale pipe-pipe and pipe-flange welding For example, for oil pipelines (the pipe diameter can reach more than 2 meters), the existing open gear transmission method is prone to slipping and axial movement during the working process, and at the same time cannot meet the requirements of automatic welding equipment and positioner synchronous linkage Requirements, many inconveniences to welding

Embodiment Construction

[0029] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0030] The positioner shown in Figure 1 includes a frame body 1, a rotation displacement mechanism 2 arranged on the frame body 1, and a rotation displacement mechanism 2 arranged on the frame body 1 to drive the rotation Displaced transmission mechanism 3.

[0031] Wherein, as the rotary displacement mechanism 2 shown in accompanying drawing 2 to accompanying drawing 4, it comprises the rotating disk 21 that has cavity 212, and the diameter of rotating disk 21 can be made larger, and corresponding cavity 212 is also opened larger, This can accommodate pipe fittings of different diameters and sizes to be welded.

[0032] The turntable 21 is also radially provided with a gap 211 communicating with the cavity 212, through which the pipe fitting 6 to be welded can be conveniently inserted into the cavity of the turntable, so this kind of positioner Also known a...

Abstract

The present invention provides one kind of locating machine for ring welding of large pipes. The locating machine includes one frame, one rotary locating mechanism on the frame, and one driving mechanism to drive the rotary locating mechanism. The rotary locating mechanism includes one turntable with cavity, one chain around the turntable and one pipe clamping and locating mechanism. The driving mechanism includes at least one driving chain wheel meshed with the chain. The present invention can ensure the stability of the welding process.

Description

technical field [0001] The invention relates to the field of welding process equipment, in particular to a positioner for girth welding of large pipe fittings. Background technique [0002] The positioner is a device used to drag the workpiece to be welded to move the weld seam to the ideal position for welding operation. The initial position of the weld seam to be welded may be in any direction in space. After the rotation and displacement movement, the weld seam to be welded in any direction becomes the welding operation of ship fillet welding, flat welding or flat fillet welding. It changes welding operations that may require vertical welding, overhead welding, etc., which are difficult to ensure welding quality. [0003] The Chinese utility model patent No. 98247370.2 discloses a U-shaped elbow girth welding positioner, which uses an open gear for transmission, and an opening is opened on the transmission gear, so that the pipe fittings to be w...
