Abstract
The utility model relates to a fixture for a large-size motor cage rotor core. The fixture comprises an upper pressing plate, a lower pressing plate, a pull rod and a sleeve, wherein the sleeve is installed on an inner circle of the rotor core, an outer circle of the sleeve is matched with the inner circle of the rotor core, and the length of the sleeve is smaller than or equal to the length of the rotor core. The upper pressing plate is arranged on the top of the rotor core, the lower pressing plate is arranged on the bottom of the rotor core, and the pull rod passes through the upper pressing plate and the lower pressing plate of the iron core to tension the rotor core. The sleeve is arranged in the rotor core to greatly reduce the deformation of the rotor core during lifting and pouring processes of the iron core. Especially, false shafts are added on the pressing plates on two ends of the rotor core to reduce the travelling demand on equipment during the processing.
Description
Technical field
The utility model relates to a kind of frock for large-size machine cage-type rotor iron core.
Background technology
At present, the rotor core of large-size machine generally is to laminate with screw rod rotor core to be fixed into an integral body afterwards, for making things convenient for handling, generally understand the mounting process pressing plate at the iron core two ends and strain with pull bar, handling process rotor iron core very easily produces distortion, easily occurs " killing " phenomenon when causing rotating shaft is installed.In addition, after rotor is installed sliver and end ring, need it is processed, be just to process behind sleeve in the past, and high to the device travel requirement, difficulty of processing is larger.
The utility model content
The purpose of this utility model is, overcomes the deficiency that prior art exists, used frock when a kind of large-size machine cage-type rotor iron core handling is provided.
The technical solution of the utility model is: a kind of frock for large-size machine cage-type rotor iron core, comprise top board, lower platen, pull bar, also comprise sleeve, described sleeve is installed on the rotor core inner circle, sleeve cylindrical and rotor core inner circle are complementary, and length sleeve is less than or equal to rotor core length.Top board is arranged at the rotor core top, and lower platen is arranged at the bottom, and pull bar passes the rotor core top board and lower platen is strained iron core.
Described sleeve is interference or interference fits with cooperating of rotor core.
Connecting bolt between top board and the sleeve is produced excessive impulsive force when preventing rotor core inclination handling, described upper cartridge is provided with seam, and described top board bottom is provided with the boss that is complementary with this seam.
In order to be beneficial to the taking-up of sleeve, described sleeve cylindrical evenly is provided with 3 or 3 above formers, and the external diameter of described former and rotor core internal diameter are complementary.
In order to be beneficial to the handling of rotor core, be provided with the handling seat at top board, handling seat bottom is bolted together with the rotor core top board.
In order to be beneficial to the processing of rotor core end ring and sliver, increase dummy shaft at the rotor core two ends, described dummy shaft I is installed on the top board, and the dummy shaft II is installed on the lower platen, is fixed by bolt.
Useful technique effect of the present utility model is: owing to be provided with sleeve in rotor core inside, thus greatly reduced the distortion in rotor core handling, the process of putting upside down.Particularly, increase dummy shaft at rotor core two end clamp plates, reduced to add man-hour to the stroke requirement of equipment.
