Description

[0002] Since the stator winding of the generator has been solidified into a solid whole after being dipped in paint and dried, it is not easy to remove. In order to facilitate removal, the insulation layer must be softened or burned off. After removing the old winding, the remaining insulation, paint tumors, rust spots and other debris in the winding slot must be cleaned. After cleaning the stator winding slot, use an air compressor to blow it clean.

[0003] The existing technology for cleaning the remaining insulating material in the winding slot is as follows: after the winding is removed, due to the bonding effect of the insulating paint, the insulating material remains in the winding slot, and the slot is scraped with a slot cleaning sheet, and finally a steel sand cloth strip torn into strips is pulled back and forth in the slot to clean up the residue. This cleaning method requires maintenance workers to concentrate and carefully clean each winding slot.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please refer to Figure 1 and Figure 5 As shown, a winding slot maintenance device for an electric motor comprises a fixed base 1, a transposition assembly 2 is arranged in the middle of the fixed base 1, the transposition assembly 2 is used to drive the motor stator 9 to rotate equidistantly, a positioning assembly 3 is arranged on the upper part of the transposition assembly 2, the positioning assembly 3 is used to fix the motor stator 9, a limiting rod 6 is arranged on the right side of the fixed base 1, the limiting rod 6 passes through and is slidably connected with a cleaning assembly 4, the cleaning assembly 4 is used to clean the winding slots of the motor stator 9, and a drive motor 5 is arranged at the end of the drive motor 5.

[0032] Working principle: when cleaning the winding slots of the motor stator 9, the motor stator 9 needs to be placed on the positioning component 3 so that the groove on the outer wall of the motor stator 9 is aligned with the clamping structure of the positioning component 3. At this time, let go so that the weight of the motor stator 9 applies pressure to the positioning component 3, so that the positioning component 3 moves, thereby fixing the motor stator 9. At this time, the drive motor 5 is started to move, and the drive motor 5 will drive the cleaning component 4 to move back and forth, so that the cleaning component 4 grinds the winding slots contacted by the motor stator 9. After the winding slots have been polished for a certain period of time, the worker needs to pull the cleaning component 4 by hand and then lift the transposition component 2 with his feet so that the transposition component 2 drives the positioning component 3 to rotate a certain amplitude, so that the cleaning component 4 is aligned with the next winding slot of the motor stator 9, and then let go of the cleaning component 4 so that the cleaning component 4 cleans the next winding slot. This can prevent the worker from missing the winding slots of the motor stator 9 and not cleaning them.

[0033] Embodiment 2

[0034] Please refer to Figure 2 and Figure 4 As shown, the shifting assembly 2 includes: a center column 21, a sliding cylinder 22, a fixed tooth cylinder 23, a rotating toothed member 24, and a power rod 25. The middle part of the fixed base 1 is fixedly connected to one end of the center column 21, the column body of the center column 21 is fixedly connected to the lower part of the fixed tooth cylinder 23, the groove in the middle part of the sliding cylinder 22 is slidably connected to the middle part of the fixed tooth cylinder 23, the lower part of the sliding cylinder 22 is rotatably connected to the inner wall of the rotating toothed member 24, and the lower end of the sliding cylinder 22 is hinged to the end of the power rod 25;

[0035] The sliding cylinder 22 further includes: a fixed column 221 and a spring 222. The lower part of the sliding cylinder 22 is fixedly connected with a plurality of fixed columns 221. The lower end of the sliding cylinder 22 is fixedly connected to one end of the spring 222. The other end of the spring 222 is fixedly connected to the upper part of the fixed base 1.

[0036] The power rod 25 also includes: an anti-slip rod 251 and a connecting frame 252. The groove in the middle of the power rod 25 is rotatably connected to one end of the connecting frame 252. The other end of the connecting frame 252 is fixedly connected to the upper part of the fixed base 1. The end of the power rod 25 is fixedly connected to the middle part of the anti-slip rod 251.

[0037] Working principle: When it is necessary to change the position of the winding slot of the motor stator 9, the worker needs to use the sole of his foot to support the anti-slip rod 251, and then lift it up, so that the connection between the anti-slip rod 251 and the power rod 25 moves up, so that the connection end between the power rod 25 and the lower part of the sliding cylinder 22 moves down, so that the sliding cylinder 22 drives the power rod 25 to move down, and the fixed column 221 will support the beveled teeth of the rotating gear 24 to move down during this process. When the fixed column 221 supports the beveled teeth of the rotating gear 24 and moves out of the open slot of the fixed tooth cylinder 23, there is a gap between the fixed column 221 and the beveled teeth of the rotating gear 24. The fixed column 221 causes the beveled teeth of the rotating toothed member 24 to rotate clockwise to the gap between the two fixed columns 221, and the rotating toothed member 24 drives the positioning assembly 3 to rotate by the same amplitude, so that the positioning assembly 3 drives the motor stator 9 to rotate by the amplitude of a winding slot. At this time, the foot is released, and the sliding cylinder 22 is driven to reset by the spring 222. At this time, the sliding cylinder 22 drives the rotating toothed member 24 to reset, and the beveled teeth of the rotating toothed member 24 will be stuck in the tooth groove at the lower part of the fixed tooth cylinder 23, so that the rotating toothed member 24 is limited to avoid shaking during the cleaning process of the motor stator 9.

[0038] By driving the transposition component 2 to move, the winding slots of the motor stator 9 fixed on the positioning component 3 are accurately switched, so that each action can rotate to a new winding slot without missing any winding slot. After the action is completed, the transposition component 2 will self-lock to avoid the vibration generated by the motor stator 9 during the cleaning process, which will cause the winding slot being cleaned to be offset.

[0039] Embodiment 3

[0040] Please refer to Figure 5 , Figure 7 and Figure 8As shown, the positioning assembly 3 includes: a fixed ring 31, a through groove 310, an extrusion rod 32, a connecting groove rod 321, an L-shaped rod 33, a pressure spring member 34, and a rotating shaft 35. The end surface of the fixed ring 31 is provided with a plurality of through grooves 310, the through grooves 310 are rotatably connected to the lower part of the extrusion rod 32, the lower end of the extrusion rod 32 is fixedly connected to the end of the connecting groove rod 321, the groove opened in the connecting groove rod 321 is slidably connected to one end of the L-shaped rod 33, the other end of the L-shaped rod 33 is rotatably connected to the end of the pressure spring member 34, the middle part of the L-shaped rod 33 is rotatably connected to the middle part of the rotating shaft 35, the end of the rotating shaft 35 is fixedly connected to the lower end surface of the fixed ring 31, and the middle part of the pressure spring member 34 is fixedly connected to the inner ring wall of the fixed ring 31;

[0041] The fixing ring 31 further comprises: a connecting rod 311 and a positioning groove 312. The inner ring wall of the fixing ring 31 is fixedly connected with a plurality of connecting rods 311. The ends of the connecting rods 311 are fixedly connected to the upper part of the transposition assembly 2. The upper end surface of the fixing ring 31 is fixedly connected with a plurality of positioning grooves 312. The shaft in the groove of the positioning groove 312 is rotatably connected to the upper part of the positioning groove 312.

[0042] The pressure spring component 34 also includes: a spring three 341, a power slide bar 342, and a fixed track plate 343. The middle part of the pressure spring component 34 is fixedly connected to one end of the power slide bar 342. The rod body of the power slide bar 342 passes through a hole slidably connected to the fixed track plate 343. The end of the fixed track plate 343 is fixedly connected to the inner ring wall of the fixed ring 31. The upper part of the fixed track plate 343 is fixedly connected to one end of the spring three 341. The other end of the spring three 341 is fixedly connected to the end face of the pressure spring component 34. The other end of the power slide bar 342 is rotatably connected to the end of the L-shaped rod 33.

[0043] Working principle: when placing the motor stator 9 on the positioning assembly 3, it is necessary to align the vertical groove on the outer side wall of the motor stator 9 with the position of the extrusion rod 32. After the two are aligned, the clamping state of the motor stator 9 is released. At this time, the motor stator 9 will exert pressure on the pressure spring component 34 due to the influence of gravity, so that the pressure spring component 34 moves downward, and the pressure spring component 34 drives the power slide bar 342 to move, so that the power slide bar 342 slides under the restriction of the fixed track plate 343, and the connecting end of the power slide bar 342 and the L-shaped rod 33 moves downward, so that the connecting section of the L-shaped rod 33 and the connecting groove rod 321 is tilted, and the through groove 310 can adapt to the rotation amplitude of the L-shaped rod 33 to avoid the rotation of the L-shaped rod 33 being affected, and the L-shaped rod 33 will The connecting slot rod 321 slides in the slot, so that the L-shaped rod 33 applies a thrust to the connecting slot rod 321, causing the connecting slot rod 321 to rotate. Because the upper part of the positioning slot member 312 is rotatably connected to the inner wall of the slot of the positioning slot member 312, the rotation of the positioning slot member 312 will be restricted by the positioning slot member 312, and the rotation of the connecting slot rod 321 will drive the extrusion rod member 32 to rotate, so that the extrusion rod member 32 is close to the vertical slot of the motor stator 9, and the extrusion rod member 32 applies a synchronous clamping to the vertical slot of the outer wall of the motor stator 9, thereby limiting the motor stator 9. Through the actions of the above steps, the winding slot of the motor stator 9 and the position of the cleaning component 4 can also be initially positioned, so that the cleaning component 4 can be aligned with the winding slot of the motor stator 9.

[0044] By setting the positioning component 3, the motor stator 9 can be fixed, and the initial winding slot of the motor stator 9 can also be positioned, so as to cooperate with the cleaning component 4 to clean the winding slot, so that the rotation of the transposition component 2 can also accurately switch the next winding slot of the motor stator 9 to avoid any winding slot being skipped and not cleaned.

[0045] Embodiment 4

[0046] Please refer to Figure 3 and Figure 6As shown, the cleaning assembly 4 includes: a driving disk 41, a power column 411, a pressure rod 42, a retracting rod 43, a grinding piece 44, a force rod 441, a sliding column 45, and a special-shaped groove plate 451. The output end of the driving motor 5 is fixedly connected to the middle part of the driving disk 41, the end surface of the driving disk 41 is fixedly connected to the end of the power column 411, the column of the power column 411 is slidably connected to the groove of the special-shaped groove plate 451, the upper part of the special-shaped groove plate 451 is fixedly connected to one end of the sliding column 45, the column of the sliding column 45 is slidably connected to the hole of the limiting rod 6, the other end of the sliding column 45 is fixedly connected to the lower part of the pressure rod 42, the lower part of the retracting rod 43 is fixedly connected to the upper part of the transposition assembly 2, the end of the retracting rod 43 is slidably connected to the column of the force rod 441, and the end of the force rod 441 is fixedly connected to the end of the grinding piece 44;

[0047] The pressure rod 42 further includes: a resilient member 421, a rotating pressure rod 422, and a non-return rod 423. The end of the pressure rod 42 is fixedly connected to the frame of the resilient member 421, the resilient head of the resilient member 421 is fixedly connected to the end of the rotating pressure rod 422, and the upper part of the pressure rod 42 is fixedly connected to the end of the non-return rod 423.

[0048] The retractable rod 43 also includes: a connecting plate 431 and a spring 432. The inner wall of the retractable rod 43 is slidably connected to one end of the connecting plate 431. The hole at the other end of the connecting plate 431 is slidably connected to the column of the force-bearing rod 441. The end of the connecting plate 431 is fixedly connected to one end of the spring 432. The other end of the spring 432 is fixedly connected to the end of the grinding piece 44.

[0049] Working principle: when the driving motor 5 drives the driving disk 41 to rotate synchronously, the driving disk 41 will drive the power column 411 to rotate synchronously, so that the power column 411 slides back and forth in the groove of the special-shaped groove plate 451, and the special-shaped groove plate 451 moves up and down reciprocatingly, and the special-shaped groove plate 451 is fixedly connected to the sliding column 45, so the special-shaped groove plate 451 drives the sliding column 45 to slide up and down reciprocatingly, and the sliding column 45 drives the pressure rod 42 to move up and down reciprocatingly. At this time, the pressure rod 42 drives the rotating pressure rod 422 to move synchronously. In this process, the rotating pressure rod 422 continuously reciprocates and squeezes the end of the force-bearing rod 441, so that the force-bearing rod 441 slides back and forth under the restriction of the connecting plate 431, and the spring 2 432 can drive the grinding member 44 to reset after the force-bearing rod 441 moves down, and the reciprocating grinding member 44 can be driven by the spring 2 432. The grinding piece 44 cleans the winding slots of the motor stator 9. When the transposition component 2 needs to switch the winding slots, a worker is required to push the connecting plate 431 to retract into the inner wall of the retracting rod 43 to prevent the grinding piece 44 from affecting the switching of the winding slots of the motor stator 9. When all the winding slots of the motor stator 9 have been cleaned, a worker is required to press the rotating pressure rod 422 to rotate downward, so that the motor stator 9 will not be blocked by the rotating pressure rod 422 during the removal process, and the subsequent reset of the rotating pressure rod 422 will be driven by the rebound piece 421. The spring sheet in the rebound piece 421 will drive the rotating pressure rod 422 to reset, and the rotating pressure rod 422 cannot rotate upward because the fixed check rod 423 will prevent the rotating pressure rod 422 from rotating upward, so that the rotating pressure rod 422 can only rotate in one direction.

[0050] By setting the cleaning component 4, the motor stator 9 in a fixed state can be cleaned by the reciprocating cleaning component 4, so that the winding slots can be cleaned, and the cleaning component 4 has a simple structure and is easy to maintain, and the cleaning component 4 can also avoid affecting the removal and placement of the motor stator 9.
