Problems solved by technology

However, this production process easily leads to uneven welding seams after stator assembly welding, which in turn makes the installation of the stator core and the frame cylinder not tight
In the prior art, to solve the above problems, the welding seam is usually processed by manual grinding, but the manual grinding method is more prone to poor consistency and the risk of difficulty in ensuring dimensional accuracy, and also seriously affects production efficiency.

Abstract

The invention discloses a stator core outer circle machining tool, and relates to the technical field of generator stator machining. The stator iron core outer circle machining tool comprises a mandrel, an expander, a clamping piece and a fastening piece. The expander is arranged on the periphery of the mandrel in a sleeving mode through one end of the mandrel, the fastener is connected to the endof the mandrel in a fastened mode and used for axially pressing the expander, the other end of the mandrel is connected with the clamping piece, and the end, away from the mandrel, of the clamping piece is used for being fixed to a machine tool. The stator core outer circle machining tool can achieve turning of the outer circle of the stator core, and therefore the matching precision of the stator core and the machine base is improved.

Description

technical field [0001] The invention relates to the technical field of generator stator processing, in particular to a tool for processing the outer circle of a stator iron core. Background technique [0002] The military special generator consists of a stator, a rotor, an end cover, and a machine base. The stator core is tightly installed with the outer cylinder of the machine base to improve the overall ventilation and heat dissipation performance of the generator, and at the same time greatly reduce the volume of the generator. And this kind of military special generator usually adopts the direct welded stator core structure. [0003] However, in the production process of the direct-welded stator core, after the stator punching is stacked, it is usually fixed in the form of assembly welding, and then the subsequent processes such as winding and dipping are carried out, and finally pressed into the generator by a hydraulic press. Inside the base cylinder. However, this p...
