Efficient heat dissipation device of laser welding machine

The efficient heat dissipation device of the laser welding machine comprises a bottom plate, the top of the bottom plate is fixedly connected with an installation block through a supporting block, an installation groove is formed in the top of the installation block, the inner side wall of the installation groove is fixedly connected with a supporting plate through a supporting rod, and the top of the installation block is fixedly connected with a side plate. A top plate is fixedly connected to the outer side walls of the side plates, a spraying mechanism is arranged above the supporting plate, and an adjusting mechanism is arranged at the bottom of the top plate. The water pump, the water inlet pipe, the fixing block, the spray head and the water outlet pipe are used in cooperation, a welded workpiece is sprayed, heat of the workpiece is quickly dissipated, the workpiece can be conveniently taken out, follow-up machining work can be quickly carried out, machining efficiency is improved, meanwhile, water is c
