Welding device for machining metal shells of household appliances

Abstract

The invention discloses a welding device for machining a metal shell of a household appliance, and the welding device for machining the metal shell of the household appliance comprises a cross plate, a rotating plate is hinged to the center of the top of the cross plate, a limiting motor is mounted at the top of the rotating plate, a plurality of cranks are hinged to the outer side of the rotating plate, and the cranks take the circle center of the rotating plate as the center; according to the laser welding device, through mutual cooperation of the component mounting plate, the guide plate, the rotary plate, the L-shaped movable plate, the movable plate, the sliding block, the rectangular plate, the laser welding machine, the L-shaped lifting plate, the large gear, the small gear, the motor and other components, a continuous welding seam can be divided into a plurality of short sections; welding is conducted at intervals in a jumping mode, heat is dispersed and distributed, shrinkage deformation caused by local overheating is avoided, cooling time is reserved after welding of each section, the overall temperature rise gradient is reduced through heat conduction, and therefore accumulated deformation stress is counteracted.
