Large-scale stator core turnover welding device

Abstract

The invention relates to a large-scale stator core turnover welding device which comprises a bracket, a bottom plate and a backup plate, wherein a rotary shaft is mounted at the upper end of the bracket; the bottom plate and the backup plate are rotatably mounted on the rotary shaft; a front turnover air cylinder fixing seat is mounted at the front end of the bracket and is rotatably connected with a front turnover air cylinder; a piston rod of the front turnover air cylinder is rotatably connected with the middle of the lower end face of the bottom plate; a rear turnover air cylinder fixing seat is mounted at the rear end of the bracket and is rotatably connected with a rear turnover air cylinder; a piston rod of the rear turnover air cylinder is rotatably connected with the middle of the rear end face of the backup plate; a plurality of sliding rails are transversely arranged on the front end face of the backup plate; driven rollers and driving rollers are mounted on the sliding rails in a sliding manner; lock screws are mounted at the upper end and the lower end of each of the driven rollers and the driving rollers and are propped against two sides of the sliding rails; a motor is mounted on the rear end face of the backup plate; and a rotary shaft of the motor is connected with the driving rollers. The large-scale stator core turnover welding device eliminates the process that a worker manually turns over and rotates a workpiece.

Description

technical field [0001] The invention relates to the technical field of inversion welding devices, in particular to an inversion welding device for large stator cores. Background technique [0002] At present, after stacking large stator cores, it is necessary to use a crane to lift the stator cores and overturn them. The impact damage is serious, and it is not safe, and the quality cannot be guaranteed. Moreover, the currently used tooling fixtures, clamps The side wall of the punching sheet is tight, which is easy to cause deformation. Welding needs to be manually rotated and then welded, which is labor-intensive and extremely inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large-scale stator iron core flip welding device, which effectively solves the uncontrollable factors of manual operation, and can solve factors such as manpower and safety through this device. After the stator core is stacke...
