Abstract

The invention relates to an internal round self-locking hoist suitable for hoisting motor stator core, comprising a hoist receiving part; the hoist is characterized in that the hoist also comprises a pulling rod which is fixedly connected with the hoist receiving part, and two or more friction parts; the pulling rod is sequentially provided with a first positioning part and a second positioning part; connecting rods are pivotally connected between the first positioning part, the second positioning part and the friction part correspondingly; the friction carries out the arc track motion respectively through the connecting rod correspondingly to the first positioning part and the second positioning part. The internal round self-locking hoist expands outwards by the self-gravity, generates the friction force by being contacted with the internal chamber of the stator, leads the friction part and the internal chamber wall of the stator to from mechanical self-locking, and realizes reliable and quick hoisting. The internal round self-locking hoist has the advantages of simple preparation, low cost and convenient operation and usage, can greatly improve the production efficiency, and lightens the labor intensity of the workers.

Description

technical field [0001] The invention relates to equipment specially used for assembling motors, in particular to an inner circle self-locking hoisting tool suitable for hoisting stator iron cores during the assembly process of stator iron cores and casings. Background technique [0002] We know that when installing the motor stator core and the casing, since the stator core does not have a suitable hoisting position, during assembly, rely on manpower, that is, the worker lifts the motor stator, translates it to the top of the motor casing, and aligns it with the installation hole. assembly. Due to the heavy weight of the motor stator, the workers have to hold the stator and the tooling parts during installation, which is very inconvenient to operate. A little carelessness can easily cause the motor stator to collide with the motor housing, resulting in damage. Alternatively, a hook can be used to find a suitable position for the stator core of the motor to hoist, but it is ...
