[0026] The effect achieved by the whole embodiment 1 is that when the tool is used, first start the first motor 7, the first motor 7 runs to drive the threaded rod 6 to rotate, based on the threaded transmission principle, the rotation of the threaded rod 6 drives the first sliding block 5 to move horizontally in the first sliding groove 4, the first sliding block 5 in turn drives the synchronous displacement of the clamping mechanism at the top to move to the appropriate position close to the outside of the protective box body 1, at this time, the worker can conveniently manually or with the aid of instruments, place the current collector ring between the two arc-shaped clamping plates 12, then start the second motor 14, the output end drives the bidirectional screw rod 13 to rotate, because the screw rotation directions of the bidirectional screw rod 13 on both sides are opposite, the rotation will drive the two second sliding blocks 11 to move towards the current collector ring direction, so as to firmly clamp the current collector ring, then, the output shaft of the first motor 7 is reversed, drives the clamping assembly and the clamped current collector ring to move towards the inside of the protective box body 1, in this way, the strength of manual direct carrying and operation can be reduced in the process of assembling the current collector ring, thereby the assembly efficiency is improved, and the guiding effect of the sliding assembly is relied on, so that the clamping assembly moves stably and accurately, thereby the assembly precision of the current collector ring is improved, so that the generator current collector ring assembly work is efficiently and high-quality completed.

[0027] As shown in embodiment 2, Figures 2-4 The outer wall of the protective box body 1 is fixedly installed with two hinges 19, the rotating ends of the two hinges 19 are fixedly connected with an inspection cover 20, the outer surface wall of the inspection cover 20 is fixedly installed with a handle 21, the outer surface wall of the inspection cover 20 is provided with a limiting groove 22, the outer surface wall of the protective box body 1 is provided with two installation grooves 23, the inner surface walls of the two installation grooves 23 are fixedly connected with return springs 24, the outer surface walls of the two return springs 24 are fixedly connected with a pull plate 25, the top of the pull plate 25 is fixedly connected with two fixed plates 26, the outer walls of the two fixed plates 26 are fixedly connected with limiting rods 27, and the outer surface walls of the two limiting rods 27 are movably inserted into the two limiting grooves 22.

[0028] The effect achieved by the whole embodiment 2 is that: during the use of the tooling, when the maintenance work of the collector ring and the carbon brush inside the protection box 1 is needed, first pull the pull plate 25, the pull plate 25 is forced to drive two limit rods 27 to translate outward, until the limit rod 27 is completely removed from the corresponding limit slot 22, so as to release the fixed constraint of the maintenance cover 20, at this time, with the help of the rotating function of the two hinges 19, pulling the handle 21 can make the maintenance cover 20 rotate and open around the hinge 19, so that the maintenance personnel can clearly observe the running state of the collector ring and the carbon brush, and then carry out targeted maintenance operation, in the process of moving the pull plate 25, two reset springs 24 will be stretched, after the maintenance work is completed, the maintenance cover 20 is rotated and reset to the initial closed position, at this time, relying on the elastic restoring force of the two reset springs 24, the two limit rods 27 are pushed into the corresponding limit slot 22 again, realizing the re-fixing of the maintenance cover 20, ensuring that the maintenance cover 20 remains stable closed state during normal operation, and protecting the safe operation environment of the collector ring and the carbon brush in the protection box 1.

[0029] The working principle of the whole device is as follows: when the tool is put into use and the generator collector ring needs to be assembled, first, start the first motor 7, after the first motor 7 is started, the output shaft drives the threaded rod 6 to rotate, the rotation of the threaded rod 6 promotes the horizontal linear movement of the first sliding block 5 in the first sliding groove 4, the first sliding block 5 further drives the clamping mechanism mounted on the top thereof to move synchronously until the clamping mechanism reaches the predetermined work station close to the outside of the protective box body 1, at this position, the worker can conveniently manually or with the help of professional instruments, place the collector ring to be assembled between the two arc-shaped clamping plates 12, then, start the second motor 14, the output end of the second motor 14 drives the bidirectional screw rod 13 to rotate, because the screw rotation directions of the two sides of the bidirectional screw rod 13 are opposite, during the rotation process, the two second sliding blocks 11 will move towards each other along the opposite directions towards the position of the collector ring until the collector ring is tightly and stably clamped, then, the output shaft of the first motor 7 is reversely rotated, so that the clamping assembly and the collector ring stably clamped together are translated towards the inside of the protective box body 1, so that the generator collector ring is quickly and accurately assembled to the inside of the protective box body 1, when the maintenance operation of the collector ring and the carbon brush in the inside of the protective box body 1 is needed, first, pull the pull plate 25, after the pull plate 25 is stressed, the two fixed plates 26 and the two limiting rods 27 are moved along the horizontal direction to the outside until the limiting rods 27 completely leave the inside space of the corresponding limiting grooves 22, thereby releasing the locking constraint of the maintenance cover 20, at this time, by means of the rotation freedom provided by the two hinges 19, the worker can rotate and open the maintenance cover 20 around the hinge 19 axis by pulling the handle 21, in this way, the maintenance personnel can directly observe the actual running condition of the collector ring and the carbon brush, so as to carry out comprehensive and detailed maintenance operation, during the movement of the pull plate 25, the two reset springs 24 are synchronously stretched, so that the elastic deformation and the storage of the elastic potential energy are generated, after the maintenance work is completed, the maintenance cover 20 is rotated and reset to the initial closed state, at this time, by means of the elastic force released by the two reset springs 24 in the elastic recovery process, the two limiting rods 27 are pushed to be accurately inserted into the inside of the corresponding limiting grooves 22 again, the fastening locking of the maintenance cover 20 is realized again, so that the maintenance cover 20 always maintains the stable closed state during the non-maintenance period.

[0030] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belongs to the protection scope of the technical scheme of the present application.
