Description

Technical Field

[0001] This utility model belongs to the field of motor stator winding technology, and relates to an automatic winding mechanism for a deep well pump motor stator. Background Technology

[0002] The stator is a crucial component of an electric motor. Electric motors are used in many industrial products, and many electrical products utilize them as a driving power source. The stator is the main component of the motor, and its main component is the coil. Currently, the majority of stator manufacturing processes involve winding copper wire onto a die and then manually embedding the copper coil into the motor core. This manufacturing method has many drawbacks: it is inefficient; it requires high manual skills; and manual embedding can result in loose coils, affecting stator performance.

[0003] Many existing factories use winding mechanisms to ensure stator performance. Most winding mechanisms in factories currently use a combination of fixed guide bars and push-in guide bars to embed the coil into the stator core. However, the motor stator core is made of laminated silicon steel sheets. During the winding process, the tension on the coil may cause the teeth to warp. If the teeth warp, the coil may be scratched during embedding, leading to leakage and affecting motor performance and safety. Utility Model Content

[0014] In the aforementioned automatic winding mechanism for the stator of a deep well pump motor, the pressure block is a cylindrical structure with a diameter smaller than the inner diameter of the motor stator. A rack is provided around the pressure block, and the tooth profile on the rack matches the winding groove structure on the winding cup.

[0028] Furthermore, the rotary table 4 is provided with three sets of winding stations 8, the winding cup 5 is fixedly installed on the winding station 8, and the box at the bottom of the winding operation area 2 is provided with a motor 9, the output end of the motor 9 is connected to the rotary table 4 for transmission.

[0029] In this embodiment, the motor 9 controls the rotary table 4 to rotate. After completing the processing of a set of stations, the station is switched again to realize the wire embedding processing of the winding cup 5.

[0030] Furthermore, the coil propulsion mechanism includes a hydraulic cylinder 10, a pressure head 11, and a fixing column 12. The winding cup 5 has a cavity inside. The bottom of the hydraulic cylinder 10 is fixed in the cavity of the winding cup 5. The pressure head 11 is located above the hydraulic cylinder 10. The hydraulic cylinder 10 is connected to the pressure head 11 through a push rod. The fixing column 12 is fixed above the pressure head 11.

[0031] In this embodiment, the pressure head 11 pushes the metal coil 6 into the iron core of the motor stator 7 under the action of the hydraulic cylinder 10.

[0032] Furthermore, the outer wall of the winding cup 5 is provided with evenly distributed winding grooves 13 along the axial direction. The winding grooves 13 are elongated openings, and the metal coil 6 is wound inside the winding grooves 13.

[0033] In this embodiment, the winding groove 13 is used to place the metal coil 6. The metal coil 6 is first wound in the winding groove 13 and then pushed into the motor stator 7 during assembly.

[0034] Furthermore, the stator mounting mechanism includes a mounting plate 14, a lifting cylinder 15, and an upper pressure plate 16.

[0035] In this embodiment, the mounting plate 14 and the upper pressure plate 16 are used to support the motor stator 7, and the lifting cylinder 15 is used to control the up and down movement of the motor stator 7.

[0036] Furthermore, a movable block 18 is movably disposed in the middle of the mounting plate 14. The two sides of the movable block 18 are slidably connected to the mounting plate 14 through the sliding groove 22. A horizontal cylinder 19 is connected to one side of the movable block 18. The horizontal cylinder 19 is fixedly installed on the mounting plate 14. A circular stator lower mounting groove 21 is disposed in the center of the movable block 18.

[0037] In this embodiment, the horizontal cylinder 19 is used to control the horizontal movement of the motor stator 7, thereby facilitating the placement and removal of the motor stator 7.

[0042] Furthermore, the pressure block 24 has a cylindrical structure, and the diameter of the pressure block 24 is smaller than the inner diameter of the motor stator 7. A rack 25 is provided on the periphery of the pressure block 24, and the tooth shape on the rack 25 matches the structure of the winding groove 13 on the winding cup 5.

[0043] In this embodiment, the pressure block 24 can apply pressure to the teeth to prevent them from warping, thereby ensuring the smooth insertion of the coil and improving product quality.

[0045] In this embodiment, the coil support plate 26 can support the metal coil 6, thereby facilitating processing operations.

[0046] The working principle of this utility model is as follows:

[0047] In use, before winding the stator of the deep well pump motor, a metal coil 6 is placed on the winding cup 5 via a winding mechanism. The robot arm places the unwound motor stator 7 into the mounting slot 20 on the stator. Then, the horizontal cylinder 19 moves the stator horizontally to directly below the mounting slot 21 on the lower stator via the moving block 18. Subsequently, the pressing cylinder 23 starts working, and the pressing block 24 passes through the inside of the motor stator 7 and is inserted into the winding cup 5. The rack 25 on the periphery of the pressing block 24 is embedded in the winding slot 13. Then, the lifting cylinder 15 starts working, moving the mounting plate 14, the upper pressure plate 16, and the motor stator 7 downwards synchronously to the top of the winding cup 5. The upper pressure plate 16 lowers the motor stator 7 under the action of downward pressure and presses it onto the winding cup 5. Then, the pressing head 11 pushes the metal coil 6 into the iron core of the motor stator 7 under the action of the hydraulic cylinder 10. After the operation is completed, each cylinder is reset, the robot arm picks up the processed product, and at the same time puts in the next unprocessed product, and the process is repeated in a cycle.
