Example two:

as shown in fig. 6, the scraping bar 27 is composed of a rotating bar 34 at the inner end and a working bar 35 at the outer end, a sliding groove is formed at the free end of the rotating bar 34, and an elastic component 36 is connected between the working bar 35 and the inner end of the sliding groove; during operation, through the group's of setting up the scraping strip 27 form formula for elastic component 36 can compress tightly the working strip 35 on the stator 6 inner wall all the time, thereby greatly increased the working area of scraping strip 27, the extrusion that the scraping strip 27 also can pass through stator 6 when the motion simultaneously, and control working strip 35 slides in the sliding tray is inside, thereby adjusts the whole length of scraping strip 27, and then makes the swing of scraping strip 27 go on more stably.

The working principle is as follows: the cylinder 2 pushes the telescopic rod 3 to extend out and penetrate through the interior of the motor shell, then the annular groove of the pressing plate 7 is pressed into the end part of the telescopic rod 3, so that the inner ring side wall of the pressing plate 7 applies pressure to the extrusion surface 9, the clamping block 8 is pressed to slide into the sliding groove until the pressing plate 7 passes through the sliding groove and does not apply action force to the clamping block 8, at the moment, the clamping block 8 can be ejected out of the sliding groove under the counter-elastic force of the elastic part 10, the movement of the pressing plate 7 along the outer end of the telescopic rod 3 is limited, then the cylinder 2 drives the telescopic rod 3 to reset, at the moment, the telescopic rod 3 can push the stator 6 and the motor shell to move towards one side of the positioning column 4 through the pressing plate 7 until the end part of the stator 6 is attached to the convex ring 5 on the positioning column 4, at the moment, the two ends of the stator 6 can be effectively fixed with the pressing plate 7 through the convex ring 5, and the situation that the stator 6 and the motor shell deform when the motor stator 6 is positioned through expansion is reduced, the processing and assembling quality of the end face of the motor shell is greatly improved, meanwhile, the clamping block 8 and the pressing plate 7 which are matched with each other are arranged, time-consuming and labor-consuming alignment of the telescopic rod 3 and the pressing plate 7 before matching is not needed, the operation is simple and rapid, the processing efficiency of workers is greatly improved, and the labor burden of the workers is reduced;

when the pressure cavity 21 enters the stator 6, the pressure block 22 in the pressure cavity 21 pulls the scraping strip 27 to rotate through the pull rope 28 while moving, and the scraping effect on the impurities on the inner wall of the stator 6 is achieved, and when the other pressure cavity 21 in a pair enters the stator 6, the sliding block of the pressure cavity 21 can drive the scraping strip 27 to swing through the pull rope 28 during moving, so that the cleaning effect of the scraping strip 27 on the inner wall of the stator 6 is further promoted; the air pump 30 can pump air to the air flow channel 29 during operation, when the outer end of the telescopic rod 3 moves towards one side of the positioning column 4, the telescopic rod 3 can drive the communicating grooves 32 to be respectively communicated with the air flow grooves 31, and the inner end of the pressure cavity 21 is pumped by the air pump 30, so that the pressure block 22 in the pressure cavity 21 can reset under the action of internal air pressure, and then when the telescopic rod 3 continues to move and the air flow grooves 31 and the communicating grooves 32 are disconnected, the pressure block 22 can move towards one side close to the stator 6 again, so that the pressure bag 24 can be repeatedly driven to extrude and swing with the scraping strip 27, and the cleaning effect of the pressure bag 24 and the scraping strip 27 on the inner part of the stator 6 is better; when the stator 6 is to be completely clamped, the expansion bag 33 on the pressing plate 7 and the slip ring 11 are extruded, and the internal gas is ejected from the gas injection holes, so that impurities on the stator 6 cleaned by the scraping strips 27 can be blown from one side of the positioning column 4, and the cleanness inside the stator 6 is further enhanced; by setting the forming form of the scraping strip 27, the elastic component 36 can enable the working strip 35 to be pressed on the inner wall of the stator 6 all the time, so that the working area of the scraping strip 27 is greatly increased, meanwhile, the scraping strip 27 can also be extruded by the stator 6 during movement, the working strip 35 is controlled to slide in the sliding groove, the whole length of the scraping strip 27 is adjusted, and further the swinging of the scraping strip 27 can be carried out more stably; the rolling ball 37 at the end of the working strip 35 can reduce the resistance of the working strip 35 when moving on the inner wall of the stator 6, and meanwhile, when the scraping strip 27 slides towards the inside of the sliding groove, the internal gas can be extruded out of the gas passage 39, and the gas outlet groove 38 on the rolling ball 37 is directly sprayed on the inner wall of the stator 6, so that the cleaning effect of the scraping strip 27 on impurities inside the stator 6 is further improved.
