Description

Technical Field

[0001] The present invention relates to the technical field of motor rotor processing, and particularly to a high-precision winding system for motor rotors. Background Art

[0002] As a key device for power conversion and transmission, motors have been widely used in industrial production and daily life. As the main rotating component of the motor, the rotor plays a crucial role in the performance and efficiency of the motor. The rotor winding process is one of the key links in the motor manufacturing process. Through precise winding technology, parameters such as the number of turns, wire diameter, and arrangement of the rotor coil can be ensured to meet the design requirements, thereby improving the electromagnetic performance and operating efficiency of the motor.

[0003] For example, in the Chinese patent with the publication number CN115589120A and the name "Motor Rotor Winding Loading Device", it includes a frame and a horizontally arranged workbench. Two bases are rotatably fitted in the workbench. A clamping member is connected to the upper end of the base. A rectangular groove is opened at the lower end of the base. A plate body is matched and arranged in the rectangular groove. A telescopic member is arranged below the plate body to drive the plate body to move so that the plate body is inserted into or disengaged from the rectangular groove. The two clamping members are used alternately. When one clamping member is performing the winding operation, the other clamping member that has completed the winding operation is used for material taking and loading operations. This motor rotor winding loading device does not require the rotor to be removed after stopping, improves the continuity of the rotor winding work, and saves operation time; in the base, the setting of the first permanent magnet and the second permanent magnet assists the column body to rotate and reset, avoiding the column body rotating and shifting when clamping or removing the rotor, and unable to control the plate body to smoothly insert into the interior of the rectangular groove.

[0004] Although the motor rotor winding loading device in the above patent is practical and convenient, it also has deficiencies. Before winding the rotor, it is necessary to clamp the rotor, adjust the axial center height of the winding shaft so that the axial center is at the middle height of the rotor, and also adjust the height of the winding head according to the length of the rotor. The time spent on the preparatory steps and replacing parts is too much, reducing the winding efficiency of the overall device. Summary of the Invention

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0029] Please refer to Figures 1 - 9 , a technical solution provided by an embodiment of the present invention: The high-precision wire winding system for an electric motor rotor includes a base 1, a linkage assembly, and a transmission assembly. A side plate 3 and a machine table 2 are fixedly arranged on the base 1. A clamping plate 13 is vertically slidably connected to one side of the side plate 3 close to the machine table 2. A driving assembly for driving the vertical sliding connection of the clamping plate 13 is provided on the base 1. A wire winding shaft 25 is vertically slidably connected to one side of the machine table 2 close to the side plate 3. The wire winding shaft 25 is rotatably connected inside the machine table 2. One end of the wire winding shaft 25 is fixedly connected to a connecting plate 31. A wire winding head 30 is slidably connected inside the connecting plate 31 in a direction away from the axis of the wire winding shaft 25. The transmission assembly receives the drive of the vertical movement of the clamping plate 13 to vertically move the wire winding shaft 25 to the middle horizontal height of the rotor. The linkage assembly receives the drive of the vertical movement of the wire winding shaft 25 to slidably connect the wire winding head 30 for adjusting the radius of wire winding.

[0030] As a preferred technical solution, the driving component includes a pushing block 5, a mechanical gripper 6, an abutting plate 7 and a slider 11. A first chute 10 is vertically formed in the side plate 3, and a second chute 12 communicating with the first chute 10 is horizontally formed in the side plate 3. The abutting plate 7 and the slider 11 are both vertically slidably connected in the first chute 10, the pushing block 5 is horizontally slidably connected in the second chute 12, both ends of the slider 11 are fixedly connected to the abutting plate 7 and the clamping plate 13 respectively. The side of the abutting plate 7 close to the pushing block 5 is inclined. One side of the pushing block 5 close to the machine table 2 is provided with a mechanical gripper 6 for transporting and clamping the rotor. One side of the pushing block 5 is slidably abutted against one side of the abutting plate 7. Specifically, the mechanical gripper 6 clamps the rotor to be wound and moves horizontally with the pushing block 5. One side of the pushing block 5 is slidably abutted against the inclined side of the abutting plate 7, pushing the abutting plate 7 to move upward. At the same time, the clamping plate 13 is driven by the slider 11 to move upward synchronously. When the rotor is directly below the clamping plate 13, the mechanical gripper 6 releases the clamping and moves out with the pushing block 5. The abutting block, the slider 11 and the clamping plate 13 move downward due to their own gravity, realizing that the clamping plate 13 can clamp rotors of different lengths, improving the adaptability of the overall device.

[0031] As a preferred technical solution, a guide rod 8 is vertically arranged in the first chute 10, a first spring 9 is sleeved on the guide rod 8, both the slider 11 and the abutting plate 7 are vertically slidably sleeved on the guide rod 8, and both ends of the first spring 9 are fixedly connected to the slider 11 and the top wall of the first chute 10 respectively. Specifically, the guide rod 8 plays a guiding role, making the moving direction of the clamping plate 13 can only be a vertical linear movement, and the cooperation of the first spring 9 and the guide rod 8 can play a buffering role to avoid the clamping plate 13 falling instantaneously and damaging the rotor.

[0032] As a preferred technical solution, a cylinder 4 is arranged on the base 1, and the output end of the cylinder 4 is fixedly connected to one side of the pushing plate. Specifically, the cylinder 4 drives the horizontal movement of the mechanical gripper 6 and the pushing block 5 to realize the horizontal transportation of the rotor to be wound.

[0033] As a preferred technical solution, the transmission assembly includes a connecting bracket 15, a worm gear 20, a worm 21 meshing with the worm gear 20, a turntable 22, a screw rod 23, a sliding bracket 24, a rack 17, and a gear 18 meshing with the rack 17. Both ends of the connecting bracket 15 are fixedly connected to the clamping plate 13 and the rack 17 respectively. The gear 18 is rotatably connected in the machine table 2. A connecting shaft 19 is provided between the gear 18 and the worm gear 20. The worm 21 is vertically rotatably connected in the machine table 2. Both ends of the turntable 22 are fixedly connected to the worm 21 and the screw rod 23 respectively. The sliding bracket 24 is screwed to the screw rod 23. The sliding bracket 24 is vertically slidably connected in the machine table 2. The winding shaft 25 is rotatably connected in the sliding bracket 24. Specifically, the clamping plate 13 drives the rack 17 to move through the connecting bracket 15. Through the meshing transmission between the rack 17 and the gear 18, the gear 18 drives the worm gear 20 to rotate through the connecting shaft 19. Through the meshing transmission between the worm gear 20 and the worm 21, the worm 21 drives the turntable 22 to rotate, so that the turntable 22 drives the screw rod 23 to rotate. A third sliding groove 34 is vertically formed in the machine table 2. The sliding bracket 24 is vertically slidably connected in the third sliding groove 34. Since the third sliding groove 34 restricts the circumferential rotation of the sliding bracket 24, the sliding bracket 24 is driven to vertically slide through the screw transmission of the screw rod 23. The sliding bracket 24 drives the winding shaft 25 to vertically move, so that the axis height of the winding shaft 25 is always the same as the middle height of the rotor, which can match the change of the center of the winding shaft 25 of rotors of different lengths, save the time for replacing different parts for adapting to different rotors, and improve the winding efficiency and adaptability of the overall device. Preferably, a motor is provided on one side of the sliding bracket 24 away from the winding head 30. The output end of the motor is coaxially and fixedly connected to the winding shaft 25 for driving the winding shaft 25 to rotate for winding operation.

[0034] As a preferred technical solution, the linkage assembly includes a hinge rod 29, a frustum 26, and a baffle 35. The baffle 35 is arranged in the machine table 2. The frustum 26 is slidably sleeved on the winding shaft 25. The bottom of the baffle 35 is slidably abutted against the circumferential side surface of the frustum 26. Both ends of the hinge rod 29 are hinged to the winding head 30 and the frustum 26 respectively. Specifically, during the vertical movement of the winding shaft 25 along with the sliding bracket 24, the frustum 26 is slidably abutted against the baffle 35, and the frustum 26 horizontally slides along the length direction of the winding shaft 25. The winding head 30 is pushed to slide in the clamping plate 13 through the hinge shaft, which can adapt to the winding radius of rotors of different lengths and improve the winding efficiency and adaptability of the overall device.

[0035] As a preferred technical solution, a sliding hole 33 is formed in the connecting plate 31. A limiting rod 32 is arranged in the sliding hole 33. The winding head 30 is slidably sleeved on the limiting rod 32. Specifically, through the cooperation between the sliding hole 33 and the limiting rod 32, the winding head 30 is guided and limited to prevent the winding head 30 from sliding out and falling off.

[0036] As a preferred technical solution, a telescopic rod 27 is provided between the frustum 26 and the connecting plate 31. A second spring 28 is sleeved on the telescopic rod 27. Specifically, when the wire winding shaft 25 drives the connecting plate 31 to rotate for wire winding, through the connection of the telescopic rod 27, the frustum 26 rotates synchronously. And due to the acting force of the second spring 28 and the acting force of the baffle 35, the frustum 26 can be prevented from shifting in the horizontal position.

[0037] As a preferred technical solution, a support column 16 is provided on the base 1. Specifically, the support column 16 can cooperate with the clamping plate 13 to clamp the rotor, and at the same time can raise the height of the rotor to facilitate the wire winding head 30 to wind the wire.

[0038] As a preferred technical solution, a wire winding base 14 is provided on the clamping plate 13. Specifically, it provides the copper wire required for the wire winding head 30 to wind.

[0039] Working principle: In this motor rotor high-precision wire winding system, the air cylinder 4 drives the horizontal movement of the mechanical clamping jaw 6 and the pushing block 5 to realize the horizontal transportation of the rotor to be wound. The mechanical clamping jaw 6 clamps the rotor to be wound and moves horizontally with the pushing block 5. One side of the pushing block 5 is in sliding contact with the inclined side of the abutting plate 7, pushing the abutting plate 7 to move upward. At the same time, the slider 11 drives the clamping plate 13 to move upward synchronously. When the rotor is directly below the clamping plate 13, the mechanical clamping jaw 6 releases the clamping and moves out with the pushing block 5. The clamping plate 13 moves downward through the gravity of the abutting block, the slider 11 and itself, realizing that the clamping plate 13 can clamp rotors of different lengths, improving the adaptability of the overall device. And the clamping plate 13 drives the rack 17 to move through the connecting bracket 15. Through the meshing transmission of the rack 17 and the gear 18, the gear 18 drives the worm wheel 20 to rotate through the connecting shaft 19. Through the meshing transmission of the worm wheel 20 and the worm 21, the worm 21 drives the turntable 22 to rotate, and the turntable 22 drives the screw rod 23 to rotate. A third chute 34 is vertically opened in the machine table 2, and the sliding bracket 24 is vertically and slidably connected in the third chute 34. Since the third chute 34 restricts the circumferential rotation of the sliding bracket 24, the sliding bracket 24 is vertically slid by the screw drive of the screw rod 23. The sliding bracket 24 drives the wire winding shaft 25 to move vertically, so that the axis height of the wire winding shaft 25 is always the same as the middle height of the rotor, which can match the change of the center of the wire winding shaft 25 of rotors of different lengths, saving the time for replacing different parts for different rotors, improving the wire winding efficiency and adaptability of the overall device. At the same time, during the vertical movement of the wire winding shaft 25 with the sliding bracket 24, the frustum 26 is in sliding contact with the baffle 35, and the frustum 26 slides horizontally along the length direction of the wire winding shaft 25. The wire winding head 30 is pushed to slide in the clamping plate 13 through the hinge shaft, which can adapt to the wire winding radius of rotors of different lengths, improving the wire winding efficiency and adaptability of the overall device.

[0040] Only certain exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
