Welding gun swinging device and welding equipment

The utility model provides a welding gun swinging device and welding equipment. The welding gun swinging device comprises a transmission assembly, and the transmission assembly comprises a driver and a transmission box; a transmission structure and a connecting structure are arranged on the transmission box; the driver is connected with the transmission case through the connecting structure; the transmission structure is in transmission connection with the driver; the clamping device is fixed to the transmission structure, and when the driver acts, the clamping device is driven by the transmission structure to swing around a first axis; the clamping device is provided with a clamping mechanism used for clamping the welding gun, and when the clamping mechanism clamps the welding gun, the length direction of the welding gun is perpendicular to the first axis. During use, reliable control over the swing angle of the welding gun can be achieved by controlling the driver, so that the swing requirements of the weld
