Abstract
The utility model discloses a device for changing an electric motor shaft, and belongs to the field of machinery maintenance. The device comprises a push rod motor and a switch which controls the push rod motor to move back and forth horizontally. The head part of the push rod motor is fixed with a drill chuck. A rotor fixing apparatus, which is fixed on the other side of a fixed bottom plate, comprises a silicon steel sheet fixing apparatus and a commutator fixing apparatus, wherein the silicon steel sheet fixing apparatus comprises an outer frame and an inner die. The outer frame and the bottom plate are welded together, and the inner die can be changed according to the sizes of different types of rotors, thereby ensuring that the inner die just butts against a silicon steel sheet and does not contact with a winding so as to ensure that the winding is not damaged. The inner die is concave so that a rotor does not waggle left and right in a shaft-changing process. The circle centers of different dies and the axis of the drill chuck are located in a line, and thus the dies are firmly fixed to the outer frame with screws. The commutator fixing apparatus, which is located behind the silicon steel sheet fixing apparatus, is formed by refitting of the drill chuck, can slide back and forth on a fixed baffle plate rail, and then is rotatably fixed by two screws, one on the left and one on the right. Moreover, the diameter of the head part of the commutator fixing apparatus can be adjusted according to the diameter of the electric motor shaft to be slightly greater than the diameter of the electric motor shaft, so that the head part can exactly butts against a commutator. The silicon steel sheet fixing apparatus and the commutator fixing apparatus of the rotor fixing apparatus are respectively used for fixing the silicon steel sheet and the commutator, thereby ensuring that the winding is not pulled apart in the whole shaft-changing process. Sliding fit is employed in the shaft-changing process to ensure that that the axes of two shafts are opposite to each other. The device provided by the utility model is convenient for changing the rotor shaft of the electric motor, is not likely to damage the rotor winding of the electric motor, and is highly reliable and applicable.

Background technology
The motor of China is produced the history that had so far 95 years from 1917, and the sector has formed at home than more complete industrial system.In recent years, China's motor manufacturing is along with electric power development presents vitality, and production and marketing scale and economic benefit have had and increase substantially.Along with the production-scale increase of motor, Electromotor Maintenance problem seems and becomes increasingly conspicuous, and due to the wearing and tearing of rotating shaft or the reason such as the length of rotating shaft is improper, makes the replacing problem of rotating shaft comparatively outstanding.For the replacing problem of micro-machine, most situation is that hand-hydraulic changes axle, and efficiency is lower, but also easily bearing or winding is destroyed.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of device that can automatically change motor rotary shaft.
For achieving the above object, the utility model provides following technical scheme:
First be the firm banking of an irony, be fixed with a push-rod electric machine in a side of firm banking, as change rotating shaft major impetus, one side of push-rod electric machine is a switch of controlling push-rod electric machine, can control push-rod electric machine slides in the horizontal direction, and at the opposite side of push-rod electric machine, phaseswitch is housed, be used for controlling the stroke of push rod, prevent the mechanical failure causing due to operate miss, the head of push-rod electric machine be one with the fixing drill chuck of push rod, the diameter that can change as required rotating shaft does flexibly to be adjusted, at the opposite side of firm banking, it is a rotor fixing device, this device comprises several different moulds, can change according to different rotor models, this rotor fixing device also can be adjusted the distance of rotor and commutator fixture and the size of commutator fixture internal diameter neatly simultaneously, there is the function of the machine shaft of main flow specification on replaceable market.
The beneficial effects of the utility model are: the device that adopts automatic replacing motor rotary shaft described in the utility model, there is the characteristic that changes flexibly rotor fixing device according to different size motor, can conveniently change the rotating shaft of motor, adopt this device can overcome the deficiency of conventional manual replacing rotating shaft.The present invention is convenient to change motor rotor shaft, and easy damaged rotor winding not, has high reliability and applicability.
Brief description of the drawings
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, Figure 2 and Figure 3, electrodynamic machine changes shaft device.Comprise a push-rod electric machine (1), control the switch moving forward and backward in the horizontal direction (2) of push-rod electric machine, be fixed wtih a drill chuck (3) at push-rod electric machine head.Be positioned at the opposite side of fixed base plate, silicon steel sheet fixture comprises housing (4) and inner mould (5), wherein housing (4) and base plate welding, and inner mould (5) can be changed according to different rotor model size, ensure it just in time to conflict silicon steel sheet and do not contact with winding, thereby ensure that winding can be not destroyed, grinding tool indent, make change axle process rotor can double swerve, the center of circle on different moulds all with drill chuck (3) axle center on a line, mould (5) is fixing better by screw with housing (4).It after silicon steel sheet fixture, is commutator fixture, this device by drill chuck through converting, can before and after fixed dam track (6) is upper, slide, then fixing by two screws in left and right (7) rotation, and head bore (8) can be according to the diameter adjustment of rotating shaft, make it be a bit larger tham rotating shaft diameter, thereby just in time conflict commutator, two parts silicon steel sheet fixture and the commutator fixture of rotor fixing device are fixed respectively silicon steel sheet and commutator, ensure whole change axle process in winding can not be torn, in the process of changing axle, use be slidably matched (9) to ensure that diaxon axle center is relative.
In the time using device described in the utility model, the first step: select suitable mould (5) according to rotor specification size, make silicon steel sheet fixture just in time can prop up silicon steel sheet and can not contact winding, then fix rotor.Second: adjust commutator fixture, make its aperture be a bit larger tham rotating shaft, then slide and adjust its position in front and back, makes its commutator of just in time conflicting.The 3rd step: the new rotating shaft that will change is arranged on drill chuck (3), turn locking drill chuck, rotating shaft can not be moved left and right, but can move forward and backward, in its one be slidably matched (9) of head suit, ensure that the axle center in whole process is relative simultaneously.Finally turn on the power switch (2), push-rod electric machine promotes forward, and new axle replaces old axle, controls push-rod electric machine and rotates backward, and new axle automatic trip, from drill chuck (3), completes the replacing of rotating shaft.
