Description

Rotor or stator hanger

Technical Field

The utility model belongs to the lifting device field, concretely relates to rotor or stator hoist.

Background

In the assembling process of the motor, a winding stator core is required to be pressed into the base, copper wire windings are arranged at two ends of the winding stator core, the structural strength is low, and therefore the winding is horizontally placed to protect the winding when the winding stator core is placed. During assembly, the stator core is required to be placed on the V-shaped base plate, the winding stator is turned and erected by using the turning cage, then the stator is expanded and lifted by using the expansion lifting appliance from the inside of the stator core, and through multiple operations, the process is complicated, and the stator inevitably generates strong vibration or collision in the process, so that the stator generates a knocking mark phenomenon, and the motor assembly or the motor performance is influenced; and the stators with different outer diameters need to be provided with special overturning cages, so that the equipment investment for motor production is very large.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rotor or stator hoist can accomplish lifting by crane and the upset of rotor or stator in step, and avoids it to lift by crane or the phenomenon of colliding with takes place among the upset process.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a rotor or stator hoist, wholly is the axle sleeve that the level was arranged to concentric, and the inboard face that the axle body was located the axostylus axostyle in the axle sleeve is provided with magnetic force relatively and inhales the piece that the lower extreme of two montants of U-shaped jib that open side is provided with, the inboard face that the piece was inhaled to magnetic force is V-arrangement or curved actuation face, axostylus axostyle and axle sleeve be connected for the movable fit.

Adopt above-mentioned scheme, the control axostylus axostyle is axial slide in the axle sleeve, accomplishes the magnetic force and inhales the piece and inhale rotor or the stator outer wall that the piece was laid down closely, lifts by crane the back, and the control axostylus axostyle rotates in the axle sleeve, accomplishes the upset of rotor or stator, and the process is steady, and rotor or stator do not take place to collide with other equipment, avoids producing indentation or damage, the utility model discloses a scheme unites two into one tipping arrangement and lifting by crane equipment, avoids the phenomenon of colliding with that conversion equipment brought, has also simplified motor assembly step, has reduced intensity of labour, has improved work efficiency.

In the figure: 10-U-shaped suspender, 11-vertical rod, 12-shaft sleeve, 20-shaft rod, 21-pin shaft seat, 22-end, 30-magnetic attraction block, 31-attraction surface, 32-soft cushion, 33-attraction block seat, 34-pin shaft and A-stator

Detailed Description

The technical solution of the present invention will be further described with reference to the accompanying drawings.

The utility model provides a rotor or stator hoist, wholly is the lower extreme of two montants 11 of U-shaped jib 10 that open side down and is provided with the axle sleeve 12 that the level was arranged to concentric, and the axle body is located the inner end of axle lever 20 in axle sleeve 12 and is provided with magnetic force relatively and inhales piece 30, and the inboard face that magnetic force inhales piece 30 is V-arrangement or curved actuation face 31, axle lever 20 be connected for the movable fit with axle sleeve 12.

Before hoisting, the sling is firstly placed above a horizontally placed rotor or stator, the axial sliding of the shaft rod 20 in the shaft sleeve 12 is controlled to adjust the distance between the two magnetic suction blocks 30, the rotor or stator workpiece is contacted and sucked tightly, the axis of the rotor or stator is enabled to be in the same plane with the axis of the shaft rod 20 as much as possible, so that the rotor or stator is lifted and overturned stably, the damage caused by collision of the rotor or stator in the process is avoided, time and labor are saved simultaneously, the hoisting working efficiency is improved, and the labor intensity is reduced.

Preferably, in order to prevent the outer wall of the rotor or the stator from being damaged when the magnetic attraction block 30 contacts with the rotor or the stator, a soft pad 32 is attached to the attraction surface 31 of the magnetic attraction block 30.

In order to replace the magnetic attraction blocks 30 with different models to adapt to rotors or stators with different models, the attraction surface 31 is an arc surface, the magnetic attraction blocks 30 are fixed on the attraction block seat 33, the attraction block seat 33 is hinged with the pin joint seat 21 at the end part of the shaft rod 20 through the pin shaft 34, the pin shaft 34 is positioned in the vertical direction, the T-shaped head of the pin shaft 34 is arranged upwards, and therefore the magnetic attraction blocks 30 are convenient to install and replace.

Preferably, in order to prevent the shaft 20 from slipping out of the sleeve 12, the outer end of said shaft 20 is provided with a head 22, the maximum radial dimension of said head 22 being greater than the inner diameter of the sleeve 12.

The magnetic attraction block 30 is an electromagnetic chuck. After the electromagnetic chuck is electrified, required suction can be provided, the electromagnetic chuck is directly powered off after hoisting is completed, and the electromagnetic chuck loses suction to complete separation from the rotor rear stator.
