Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of frame welding, and specifically relates to a two-wheeled electric vehicle frame assembly welding device. BACKGROUND

[0002] An electric vehicle is a vehicle that is driven by an electric motor and is powered by a vehicle-mounted power source. The core feature of the electric vehicle is that it uses electricity instead of oil, which is different from the internal combustion engine driving mode of a traditional fuel vehicle. A two-wheeled electric vehicle is a two-wheeled vehicle that uses a battery as an energy source and converts electric energy into mechanical energy through a controller and a motor to drive the vehicle to travel. According to relevant standards, two-wheeled electric vehicles can be divided into three categories: electric bicycles, electric mopeds and electric motorcycles. A two-wheeled electric vehicle frame assembly is each component that constitutes a frame, mainly including a main frame, a rear fork, a middle support, a side support, a rear cargo rack and a handlebar, which collectively provide support and connection for the vehicle. A welding device is a complete set of equipment required to realize a welding process, and its core function is to provide energy to connect two or more workpieces into a whole. It is not only an indispensable basic equipment in industrial manufacturing, but also a key tool for ensuring welding quality and improving production efficiency. A two-wheeled electric vehicle frame assembly needs to use a welding device during processing, and therefore a two-wheeled electric vehicle frame assembly welding device is needed.

[0003] The existing two-wheeled electric vehicle frame assembly welding device uses a welding gun to weld a fixed two-wheeled electric vehicle frame assembly. When welding a large number of two-wheeled electric vehicle frame assemblies, the welding gun uses a one-way supply of protective gas in an open-loop mode. After welding, the protective gas rich in inert gas is directly emptied, and during the welding process, the welding gun continues to discharge at a fixed flow rate during movement, resulting in a large amount of waste of protective gas, high gas use cost during the welding process, high operating cost of the welding device and poor environmental benefits, reduced use effect of the welding device and inability to meet people's needs.
