Problems solved by technology

[0003] During the processing of the rotor core inside the large motor, the rotor core is welded by stacking multiple rotor punches. The welding process needs to align the cooling holes on the multiple rotor punches to prevent welding deviation. Currently Alignment and stacking are done by human visual inspection, and the error is relatively large, and the rotor punches are also easily deviated by external forces after stacking

Abstract

The invention relates to the field of iron cores, in particular to a rotor iron core, which includes a rotor punching piece, a positioning guide structure, a supporting structure and a clamping structure. The positioning and guiding structure is connected to the rotor punching piece, and the positioning and guiding structure includes External thread, positioning column and limit cross bar. The surface of the rotor punching sheet is provided with several heat dissipation positioning cavities arranged around it. One end of the positioning column passes through several heat dissipation positioning cavities on the stacked rotor punching pieces. The outer side walls at both ends of the positioning column are respectively An external thread is provided, and the two ends of the positioning column are threadedly connected to the limit cross bar; the supporting structure is connected to the rotor punching piece, and the number of the clamping structures is two, and the two clamping structures are connected to the supporting structure. The rotor iron core provided by the invention has the advantages of a guiding and positioning structure, which is not easily affected by external influences after being sleeved, and can be quickly stacked in a corresponding manner.

Description

technical field [0001] The invention relates to the field of iron cores, in particular to a rotor iron core. Background technique [0002] The motor rotor is also the rotating part in the motor. The motor consists of two parts, the rotor and the stator, which are used to realize the conversion of electrical energy and mechanical energy and mechanical energy and electrical energy. The motor rotor is divided into a motor rotor and a generator rotor. [0003] During the processing of the rotor core inside the large motor, the rotor core is welded by stacking multiple rotor punches. The welding process needs to align the cooling holes on the multiple rotor punches to prevent welding deviation. Currently Alignment and stacking are performed by human visual inspection, and the error is relatively large, and the rotor punches are also easily deviated by external forces after stacking. Therefore, it is necessary to provide a new rotor core to solve the above technical problems. ...
