Description

Technical Field

[0001] The utility model belongs to the technical field of flange production equipment, in particular to a laser welding nozzle for flange water channel welding. Background Art

[0002] Flange is a mechanical connector, commonly used in the connection parts of pipes, valves, pumps and other equipment. The main function of the flange is to connect and seal the pipeline system to ensure the safe transmission of fluids or gases. A water channel is usually opened inside the flange, and the water channel inside the flange is sealed by laser welding of the water sealing plate. However, the laser welding nozzle currently used for welding the flange water sealing plate still has the following disadvantages in actual use:

[0003] 1. At present, the welding of the water sealing plate on the flange is generally done manually by welders. Since the connection between the water sealing plate and the flange is an arc shape, the welding has high technical requirements for welders. In addition, when welders do manual welding, it is easy to cause leakage, which will cause leakage at the connection between the water sealing plate and the flange, thereby reducing the yield rate of flange production;

[0004] 2. The joints installed on the flange side wall also need to be welded, but the gap between the joint and the flange side wall is generally very narrow. The heads of the laser welding nozzles on the market are relatively wide, which makes it inconvenient for welders to weld the joints and flanges.

[0005] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of the utility model is to provide a laser welding nozzle for flange water channel welding.

[0009] Furthermore, the welding nozzle assembly includes a handle plugged into the inner wall of the plug sleeve, the outer wall of the handle is fixedly mounted with a laser welding nozzle body, and the upper end of the outer wall of the laser welding nozzle body is fixedly connected with a connecting cable.

[0010] Furthermore, a locking screw 1 is threadedly connected to the upper end of the outer wall of the plug sleeve.

[0011] Furthermore, a second locking screw is threadedly connected to the upper end of the outer wall of the connecting sleeve.

[0012] Furthermore, mounting rods are symmetrically fixedly installed on opposite sides of the outer walls of the left and right extrusion support blocks, and ball screw sleeves are fixedly installed on each pair of left and right mounting rods at the same time. Ball screws are threadedly connected to the inner walls of the left and right ball screw sleeves at the same time, and a rotating block is fixedly installed in the middle of the ball screw, and the thread directions of the ball screws located on the left and right sides of the rotating block are opposite.
