Description

Technical Field

[0001] This utility model relates to the technical field of pipeline welding devices, and in particular to a docking mechanism and its pipeline welding device. Background Technology

[0002] Pipe welding equipment is a specialized device used for welding pipe joints. It is mainly used to connect pipe fittings. Depending on the pipe thickness and welding requirements, it is mainly divided into two types: closed and open. It can realize automated welding and is suitable for various materials and scenarios.

[0003] When installing pipes, workers install two pipes against each other. During the welding process, external forces can easily cause the pipes to vibrate, and the two pipes may shift due to different vibrations. Workers need to re-fix or manually tap to readjust the pipes. In addition, workers need to constantly adjust the pipe angles to adapt to the position of the welding gun during the welding process, which is time-consuming and labor-intensive.

In specific use: the clamping mechanism is used to fix the position of the pipe, and the docking mechanism is used to fix the two fixed cylinders 3. When external force is encountered during welding, the vibration amplitude of the two fixed cylinders 3 tends to be consistent, preventing the two pipes from shifting due to external force. The rotary drive mechanism is used to adjust the pipe angle, eliminating the need for manual adjustment by workers, saving time and effort.

[0019] In one aspect, there are two fixed cylinders 3 arranged horizontally and symmetrically. The docking mechanism includes a first collar 5 and a second collar 6.

The inside of the second collar 6 is connected to the fixed cylinder 3. The outer walls are attached together, and multiple connecting rods 17 are arranged at circumferential intervals. The connecting rods 17 are used to connect the two fixed cylinders 3. During pipe installation, the pluggable nature of the connecting rods 17 makes it convenient for workers to adjust the two pipes. After the pipe is installed, the second ring 6 is used to drive the connecting rods 17 to engage with the slots 4. In specific use: after the pipe is installed, the second ring 6 is used to drive multiple connecting rods 17 to move until multiple connecting rods 17 engage with the slots 4, so as to make the vibration amplitude of the two fixed cylinders 3 tend to be consistent.

[0021] In addition, there are two clamping plates 15 arranged horizontally and symmetrically. Anti-slip pads 14 are fixedly connected to the outer walls of the two clamping plates 15.
