Full-automatic topological expanding machine for stator coil of megawatt wind power generator

Abstract

The invention discloses a stator coil completely-automatic topology expansion machine used for an MW wind power generator, belong to the filed of motor equipment technique. The topology expansion machine comprises a machine body, a linear edge expansion arm mechanism, a nose clamp mechanism and a hydraulic station; the topology expansion machine is characterized in that the middle part of the machine body is provided with an expansion arm core shaft; the linear edge expansion arm mechanisms have two groups which are respectively sleeved on the front part and the rear part of the expansion arm core shaft; a radius magnification mechanism is sheathed on the linear edge expansion arm mechanism which extends for expansion by rotating correspondingly to the same expansion arm core shaft from a vertical state to a horizontal state; the nose clamp mechanism is provided with two groups which are respectively arranged at the left side and the right side of the expansion arm core shaft; the nose clamp mechanism is provided with an automatic locking mechanism and a nose clamp axial sliding mechanism which straightens a shuttle-shaped coil. The stator coil completely-automatic topology expansion machine has the advantages of good expansion effect, high precision, and needing no recovery after expansion.

Description

technical field [0001] The invention belongs to a stator coil full-automatic topological expanding machine of a megawatt-level wind power generator, which is mainly used for expanding and forming the stator coil of a megawatt-level wind power generator. Traction motor stator coils and AC motor stator coils are formed and end-bent at one time. Background technique [0002] Stator coils are formed by a one-time forming machine when the production process is strict, especially for the stator coils of wind turbines with a service life of more than 20 years. Due to the extremely strict production process requirements, knocking is not allowed during the forming process. , No punching, no damage to the inter-turn insulation, and it is not expected to use the compound mold to re-form after forming to prevent the insulation layer of the coil from being damaged. Therefore, this type of stator coil should be automatically formed at one time by the stator coil automatic expansion machin...

Problems solved by technology

However, in the manufacturing process of this equipment, the nose is still bent and shaped through the top arc process of a positioning top arc mechanism, which needs to be completed by an automatic control mechanism such as an encoding device, so the mechanism is complicated and the accuracy is difficult to guarantee; and Since the expanding arm mandrel of the device is not on the plane formed by the upper and lower straight parts of the coil, and deviates from the center vertical line of the bed, the force is not good, and it is easy to cause the unbalanced swing of the bed.
