This technical scheme stacks after the pressfitting when the silicon steel sheet, and the profile modeling dovetail key can be got rid of to can form the dovetail on the iron core that the silicon steel sheet is constituteed, be used for later stage dovetail key's equipment, and can guarantee the structural rule in the dovetail, the later stage dovetail key of being convenient for equipment.
Description
Technical Field
The utility model relates to a long stator production facility field particularly, is a silicon steel sheet folds and presses accurate positioning device.
Background
In a magnetic suspension train, a long stator linear motor is one of the most core components, provides functions of suspension, guiding, traction, braking and the like for a locomotive, and mainly comprises a long stator component (an iron core and a dovetail key) and a cable which are packaged by epoxy resin. The magnetic suspension train guide rail is arranged on a track and is a magnetic suspension train guide rail; structurally, the long stator assembly consists of silicon steel laminations and dovetail keys, as shown on the right. The silicon steel lamination is formed by laminating about 360 silicon steel sheets with the length of about 1023.5mm and the thickness of 0.5mm, the silicon steel lamination is fixed on a functional piece of a circuit through three dovetail keys, and in order to meet the requirements of insulating electrical performance and weather resistance of a long stator, the whole outer surface of the long stator is encapsulated by 1.5-2 mm thermosetting epoxy resin.
Silicon steel sheet need fix a position it when overlying, and the locate mode that adopts is for fixing a position the corner of silicon steel sheet at present, and this kind of mode makes the structure dysmorphism in the dovetail that holds the dovetail key easily, causes inconvenience when later stage and dovetail key equipment.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the technical problem who exists among the prior art, provide a silicon steel sheet folds and presses accurate positioning device.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
an accurate positioning device for silicon steel sheet lamination comprises a pressing table, a pressing plate and a profiling dovetail key, wherein a limiting groove opposite to the lower end of the profiling dovetail key is formed in the pressing table, the pressing plate is arranged above the pressing table,
and the pressure plate is provided with a limiting hole opposite to the upper end of the profile modeling dovetail key.
Further inject, press the platform four corners all to be provided with the guide post, the guide post lower extreme with press platform fixed connection, the upper end is upwards extended perpendicularly, and four the guide post pierces through the four corners of clamp plate respectively. Further limiting, the cross-sectional shapes of the limiting groove and the limiting hole are the same as the cross-sectional shape of the profiling dovetail key.
Further limit, profile modeling dovetail key is provided with at least two, two square dovetail key symmetry sets up.
The utility model has the advantages that:
