[0002] Currently, in certain welding scenarios, pipe positioners are often used to rotate pipes. Existing pipe positioners often require pipes to be fixed using bolts or other methods, but this process is cumbersome. In addition, most existing pipe positioners are operated manually, which makes it difficult to guarantee the accuracy of the displacement. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a pipe positioner for welding, which can improve the ease of operation and the accuracy of positioning.

[0007] Furthermore, the shaft is a conductive shaft, and a grounded busbar assembly is fixedly connected to the frame. The busbar assembly is provided with several grounded conductive brushes for abutting against the outer circular surface of the shaft.

[0008] The beneficial effects of adopting the above technical solution are as follows: the grounding conductive brush and the busbar assembly can ground the rotating pipe, and multiple grounding conductive brushes can jointly abut against the shaft to ensure the grounding effect during the rotation of the pipe and the shaft.

[0012] Furthermore, one end of the grounding conductive brush is elastically connected to the busbar assembly, and one side of the grounding conductive brush is slidably connected to the busbar assembly.

[0013] The beneficial effects of adopting the above technical solution are as follows: the grounding conductive brush can rely on the elasticity between itself and the busbar assembly to fit tightly against the outer surface of the shaft, thereby further improving the grounding performance.

[0014] Furthermore, a slewing bearing is fixedly connected to the frame, and the second gear is rotatably connected to the frame through the slewing bearing.

[0015] Furthermore, the frame is equipped with a sealing plate assembly and a protective cover assembly. One end of the shaft and the main body of the geared motor are located inside the sealing plate assembly, while the other end of the shaft, the first gear, and the second gear are located inside the protective cover assembly. The output end of the geared motor extends into the protective cover assembly and is fixedly connected to the first gear.

[0016] The beneficial effects of adopting the above technical solution are as follows: the sealing plate assembly can encapsulate one end of the shaft and the main body of the geared motor in the whole formed by the sealing plate assembly and the frame, so as to avoid external factors affecting the operation of the shaft and the geared motor; the protective cover assembly can cover the other end of the shaft, the first gear and the second gear, on the one hand to avoid external factors interfering with the operation of the shaft, the first gear and the second gear, and on the other hand to improve the safety performance of the welding pipe positioner.

[0017] Furthermore, the rack is equipped with an inlet assembly.

[0018] The beneficial effect of adopting the above technical solution is that this setting facilitates the connection of the connection lines of components such as the geared motor and the busbar assembly.

[0019] Furthermore, the frame is equipped with an adjustment assembly for adjusting the position of the geared motor shaft.

[0020] The beneficial effects of adopting the above technical solution are as follows: the adjusting component can adjust the axis of the geared motor to help ensure that the axis of the geared motor coincides with the axis of the first gear.

[0021] Furthermore, a lifting ring is provided at the upper end of the frame.

[0022] The beneficial effects of adopting the above technical solution are: this setting facilitates the use of lifting rings to lift and transport the welding pipe positioner.

[0023] The beneficial effects of this utility model are as follows:

[0024] The lathe's three-jaw chuck can quickly clamp pipes, and after starting the geared motor, it can drive the pipe clamped by the lathe's three-jaw chuck to rotate to achieve pipe repositioning, which helps to improve the convenience of operation; and by controlling the geared motor, the pipe can be driven to rotate to any position, thereby improving the repositioning accuracy.
