Jig device for rotor cap welding in rotor assembly manufacturing system

摘要

The present invention relates to a system for manufacturing a rotor assembly, wherein, after sequential assembly of a rotor can, a rotor module, and a rotor can, when the assembled assembly is loaded into a welding jig device in order to perform a welding process of a rotor cap at a welding part, By stably clamping the shaft in the welding jig device, it is possible to solve the welding defect of the rotor cap in the manufacturing of the rotor assembly and further improve the workability of the manufacturing process of the rotor assembly. To this end, the jig device for welding the rotor of the present invention includes: a base; a jig displacement unit provided on the base and configured to move a pair of welding shaft jigs in a direction approaching or moving away from each other; a pair of welding shaft jigs each having a 'V'-shaped groove for clamping the rotor shaft by approaching from both left and right sides of the rotor shaft by the action of the jig displacement unit; and a jig rotation driving unit provided to transmit a driving force for rotation to the welding shaft jig, wherein the welding shaft jig is in close contact with the chamfered surfaces outside both ends of the rotor shaft to clamp the rotor shaft, When the shaft jig for welding rotates, welding of the rotor cap is performed.
