[0028] The working principle of the shaft welding device of the photovoltaic support is as follows:

[0030] At this time, the lower surface of the photovoltaic support is in a suspended state, the two twist valves 48 can be manually twisted in the forward and reverse directions, thereby driving the two sliders 43 to relatively approach and relatively move away, thereby pulling every two longitudinally adjacent clamp connecting blocks 47 through the connecting rods 46, thereby driving every two longitudinally adjacent clamps 38 to relatively approach and relatively move away, at this time, the two twist valves 48 can be correctly twisted, the two clamps 38 on the left side clamp the photovoltaic support on the left side, and the two clamps 38 on the right side clamp the photovoltaic support on the right side, at this time, the external air pump can be controlled, the two lifting cylinders 2 are operated, and the telescopic ends of the two lifting cylinders 2 are synchronously elongated, thereby driving the two photovoltaic supports to synchronously move upward, so that the lower surfaces of the two photovoltaic supports lose the contact relationship with the middle welding support plate 8.

[0031] At this time, the single-chip microcomputer 9 can be controlled, the two motors 36 are operated, the output shafts of the two motors 36 are synchronously rotated, thereby driving the two first screws 33 to rotate, at this time, the thread directions of the two first screws 33 are opposite, thereby driving the two sliding frames 34 to relatively approach, thereby driving the two clamped photovoltaic supports to relatively approach, in this process, the welding rod can be clamped on the contact surface of the two photovoltaic supports until the two welding surfaces are in contact, this process can be adjusted according to the welding operation to adjust the speed of the two clamped photovoltaic supports when they relatively approach, so as to add welding material at the welding interface, at this time, the worker can hold the welding gun to perform the welding operation on the two photovoltaic supports.
