Specific embodiment
The utility model is described in further detail With reference to embodiment.
Embodiment 1
As shown in Figures 3 to 6, the welding equipment of 7 copper rotor of motor of the present embodiment, including pedestal 1, fixing seat 2 and weldering
Connection mechanism；
Fixing seat 2 is mounted on pedestal 1, and fixing seat 2 is used to position and the assembly of secured core 10 and copper bar 11；
Welding mechanism includes rotating driver, main shaft 3, inertial flywheel 4, chuck 5, linear actuator and slide unit 6, and rotation is driven
Dynamic device is motor 7, and linear actuator is upset forging cylinder 8；
Two guide rails 101 with the axis parallel of iron core 10 are provided on pedestal 1, slide unit 6 is mounted on guide rail 101,
The junction of slide unit 6 and guide rail 101, which is provided with, rolls chain 9；Main shaft 3 is mounted on slide unit 6, and the end connection inertia of main shaft 3 flies
