Description

Technical Field

[0001] This utility model relates to the processing and manufacturing technology of electric motors, and in particular to a device for removing stator enameled wire. Background Technology

[0002] Disassembly of the stator coil (i.e., stator winding) is one of the key steps in motor repair or modification. During motor production, the coils of defective stators need to be removed. Since the stator coil is usually made of multiple turns of insulated copper wire and fixed in the stator core slots with insulating material, the disassembly process needs to be handled with care to avoid damaging the stator core or other components.

[0003] However, the traditional method of disassembling stator coils involves too many processing steps, is slow, and is prone to damaging the stator core. Therefore, there is a need for equipment that can speed up the processing, reduce labor intensity, and avoid damaging the stator core. Utility Model Content

The other end of the output shaft 23 is provided with a pull wire block 3. The motor 2 is fixed on the upright plate 11 through the upright plate 11 and the fixing plate 21, thereby fixing the upright plate 11 above the base plate 1. The motor 2 drives the output end 22 and the output shaft 23 to move at the other end of the base plate 1 through the through hole 12, thereby driving the pull wire block 3 to move above the base plate 1.

[0021] Please see Figures 1-3 The pull block 3 is coaxially arranged with the output shaft 23. The pull block 3 is "C" shaped. The output shaft 23 is fixed on the back of the pull block 3. The bottom surface of the pull block 3 is in contact with the top surface of the base plate 1. The output shaft 23 can be fixed on the pull block 3 through the "C" shaped pull block 3, and a cavity is formed at the other end of the pull block 3. The friction between the base plate 1 and the pull block 3 is increased by sliding the pull block 3 on the top surface of the base plate 1.

[0022] Please see Figures 1-3 An extension plate 32 is provided at the center of both sides of the pull block 3. One end of the extension plate 32 is attached to the back of the pull block 3, and a pull plate 33 is connected at the center of the other end of the extension plate 32. The cavity of the pull block 3 is divided by the extension plate 32 and the pull plate 33.

[0023] Please see Figures 1-3 A protrusion 34 is provided at the center of the outer side of the pull plate 33. The outer side of the protrusion 34 is flush with the end face of the pull block 3. The length of the protrusion 34 is the same as the width of the pull block 3. A limiting groove 31 is provided at the center of the protrusion 34. The limiting groove 31 passes through the protrusion 34. Limiting grooves 31 are provided at the upper and lower end faces of one side of the pull block 3. The limiting grooves 31 on the pull block 3 and the protrusion 34 overlap each other. The limiting groove 31 at the upper end of the pull block 3 passes through the upper end face of the limiting groove 31. The limiting groove 31 at the lower end of the pull block 3 does not pass through the lower end face of the pull block 3. The protrusion 34 is flush with the end face of the limiting groove 31 and is stored in the internal cavity of the pull block 3.

[0024] Please see Figures 1-3The limiting groove 31 is equipped with a positioning pin 4. The positioning pin 4 is located inside the three limiting grooves 31. The bottom end of the positioning pin 4 is located inside the limiting groove 31 below the pull block 3. The top surface of the positioning pin 4 is equipped with a limiting plate 41. The thickness of the limiting plate 41 is the same as the thickness of the positioning pin 4. The length of the limiting plate 41 is greater than the length of the limiting groove 31. The positioning pin 4 is placed inside multiple limiting grooves 31 at the same time, and the bottom of the positioning pin 4 is placed inside the pull block 3. The positioning pin 4 is fixed above the pull block 3 by the limiting plate 41. The positioning pin 4 is inserted between the iron core and the coil. The motor 2 is started and the pull block 3 is pulled to pull out the coil. The pull plate 33 and the protrusion 34 are added in the middle of the pull block 3 to share the pulling force of the positioning pin 4 and thus increase its service life.

[0025] Please see Figures 1-3 A pair of positioning plates 5 are symmetrically arranged on the other end of the top surface of the base plate 1. Multiple pairs of mounting holes 52 are symmetrically arranged on the bottom end of the positioning plates 5 on the top surface of the base plate 1. A limiting layer 51 is provided on the side of the positioning plate 5 facing the pull wire block 3. One end of the limiting layer 51 is attached to the outer side of the positioning plate 5. The length of the limiting layer 51 is greater than the side thickness of the positioning plate 5. Through the two positioning plates 5 and the mounting holes 52, the positions of the two base plates 1 can be adjusted according to the stator dimensions of the motor so that the stator core can be inserted.

[0026] Please see Figures 1-3 A mounting block 6 is set at the center between the positioning plates 5. A wire pulling platform 61 is set on the top surface of the mounting block 6. The wire pulling platform 61 is hollow. A wire guiding block 62 is symmetrically set on the top and bottom surfaces of the inner side of the wire pulling platform 61. The wire guiding block 62 is arc-shaped. The position of the wire pulling platform 61 can be adjusted by the mounting block 6 to adapt to motors of different sizes. The wire guiding blocks 62 symmetrically arranged inside the wire pulling platform 61 can be used to comb the coil. The wire pulling platform 61 is limited by the limiting layer 51.

[0027] During use, adjust the position of the limiting layer 51 according to the size of the motor so that the motor can stably fix the stator. Place the unqualified stator between the limiting layers 51, comb the coil between the wire management blocks 62, and insert the positioning pin 4 between the iron core and the coil. Start the motor 2, pull the wire pulling block 3 to quickly pull out the coil. Adding a pull plate 33 and a protrusion 34 in the middle of the wire pulling block 3 can extend the service life of the positioning pin 4.
