The motor sliding ring extracting tool
Technical field
The utility model relates to a kind of motor sliding ring extracting tool.
Background technology
Wire wound asynchronous motor has been widely used in the production field of industry-by-industry, in use, reasons such as material, radial beat, oval deviation transfinite its motor sliding ring owing to being subjected to, shaft coupling horizontal departure or fang bolt are loosening, cause the axial and circular runout of slip ring, make brush and slip ring contact-making surface become non-arc contact-making surface, produce spark and make the overheated scaling loss of slip ring.Reasons such as slip ring is excessive owing to brush pressure in running, circular runout, very easily cause position abrasion deformations such as cover, rotor hollow shaft and keyway in the slip ring, after the motor sliding ring scaling loss, in the replacing process owing to be subjected to condition restriction such as installation position, dismounting is difficulty comparatively, slip ring is damaged easily in unloading process again, and waste time and energy, operating efficiency is extremely low.
The utility model content
The utility model is in order to solve weak point of the prior art, and the motor sliding ring extracting tool of a kind of easy to use, time and labour saving, high efficiency is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the motor sliding ring extracting tool, comprise the cylindrical shell of cylindrical hollow structure, and cylindrical shell one end is provided with closure plate, an end opening, the outside central authorities of closure plate are provided with cone tank.
The openend excircle of described cylindrical shell is provided with ring-shaped step.
After adopting said structure, when changing motor sliding ring, only need the lead-out wire of rotor is pulled down from slip ring, be placed in the cylindrical shell by passing in the rotor hollow shaft, then the cartridge openings end is penetrated on the rotor hollow shaft, annular boss on the openend roof pressure hollow shaft of cylindrical shell, with the top cone tank that withstands on the outside central authorities of closure plate of Three-claw pull-horse leading screw, scratching slip ring can easily extract slip ring, so not only reduced damage to the slip ring structure, help the maintenance processing of pulling down slip ring is utilized again, and time saving and energy saving, fully increase work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, motor sliding ring extracting tool of the present utility model, the cylindrical shell 1 that comprises the cylindrical hollow structure, cylindrical shell 1 one ends are provided with closure plate 2, closure plate 2 can be made into integration with cylindrical shell 1, the other end opening of cylindrical shell 1, closure plate 2 outside central authorities are provided with cone tank 3, and the openend excircle of cylindrical shell 1 is provided with ring-shaped step 4.
When work is used, earlier the lead-out wire of rotor is pulled down from slip ring, be placed in the cylindrical shell 1 by passing in the rotor hollow shaft, then cylindrical shell 1 openend is penetrated on the rotor hollow shaft, annular boss on the openend roof pressure hollow shaft of cylindrical shell 1, with the top cone tank 3 that withstands on closure plate 2 outside central authorities of Three-claw pull-horse leading screw, scratching slip ring can easily extract slip ring, so not only reduced damage to the slip ring structure, help the maintenance processing of pulling down slip ring is utilized again, and time saving and energy saving, fully increase work efficiency., the openend of cylindrical shell 1 can be inserted in the rotor central shaft hole during less than rotor central shaft external diameter in the aperture of cylindrical shell 1, the ring-shaped step 4 of cylindrical shell 1 cooperates with rotor central shaft end roof pressure.
