Description

Technical Field

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

[0002] As a key device for power conversion and transmission, motors have been widely used in industrial production and daily life. The rotor, as the main rotating component of the motor, plays a vital role in the motor's performance and efficiency. The rotor winding process is one of the key links in the motor manufacturing process. Through precise winding technology, the number of turns, wire diameter, arrangement and other parameters 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, the Chinese patent with publication number CN115589120A, entitled "Motor Rotor Winding Loading Device", comprises a frame and a horizontally arranged workbench, wherein two bases are rotatably arranged in the workbench, the upper end of the base is connected to a clamping member, the lower end of the base is provided with a rectangular slot, a plate body is matched and arranged in the rectangular slot, and a telescopic member is arranged below the plate body to drive the plate body to move so that the plate body can be inserted into or removed from the rectangular slot. The two clamping members are used alternately. When one clamping member is performing a winding operation, the other clamping member that has completed the winding operation is used to take out and load the material. This motor rotor winding loading device does not require stopping the machine before removing the rotor, thereby improving the continuity of the rotor winding work and saving operation time. The first permanent magnet and the second permanent magnet are arranged in the base to assist the column in rotating and resetting, thereby avoiding the column from rotating and deflecting when the rotor is clamped or removed, and failing to control the plate body to be smoothly inserted into the interior of the rectangular slot.

[0004] Although the motor rotor winding feeding device in the above patent is practical and convenient, it also has its shortcomings.

The height of the winding head also needs to be adjusted according to the length of the rotor.

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

[0029] See also Figure 1-9 , a technical solution provided by an embodiment of the present invention: the high-precision winding system of the motor rotor includes a base 1, a linkage assembly and a transmission assembly. A side plate 3 and a machine table 2 are fixedly provided on the base 1, and a clamping plate 13 is vertically slidably connected to the side of the side plate 3 close to the machine table 2. A driving assembly for driving the clamping plate 13 to slide vertically is provided on the base 1, and a winding shaft 25 is vertically slidably connected to the side of the machine table 2 close to the side plate 3. The winding shaft 25 is rotatably connected to the machine table 2, and one end of the winding shaft 25 is fixedly connected to a connecting plate 31, and a winding head 30 is slidably connected in the connecting plate 31 in a direction away from the axis of the winding shaft 25. The transmission assembly is driven by the vertical movement of the clamping plate 13 to make the winding shaft 25 move vertically to the middle horizontal height of the rotor, and the linkage assembly is driven by the vertical movement of the winding shaft 25 to make the winding head 30 slidably connected to adjust the radius of the winding.

[0030] As a preferred technical solution, the driving assembly includes a pushing block 5, a mechanical clamp 6, an abutment plate 7 and a slider 11. A first slide groove 10 is vertically opened in the side plate 3, and a second slide groove 12 communicating with the first slide groove 10 is horizontally opened in the side plate 3. The abutment plate 7 and the slider 11 are both vertically slidably connected in the first slide groove 10, and the pushing block 5 is horizontally slidably connected in the second slide groove 12. The two ends of the slider 11 are respectively fixedly connected to the abutment plate 7 and the clamping plate 13. The side of the abutment plate 7 close to the pushing block 5 is inclined, and the side of the pushing block 5 close to the machine 2 is provided with a for transporting and clamping the rotor. The mechanical clamp 6 pushes one side of the block 5 and slides with one side of the abutment plate 7. Specifically, the mechanical clamp 6 clamps the rotor to be wound and moves horizontally with the pushing block 5. One side of the pushing block 5 slides and abuts with the inclined side of the abutment plate 7, pushing the abutment 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 clamp 6 releases the clamping and moves out with the pushing block 5. The abutment block, slider 11 and the clamping plate 13 move downward due to their own gravity, so that the clamping plate 13 can clamp rotors of different lengths, thereby improving the adaptability of the overall device.

[0031] As a preferred technical solution, a guide rod 8 is vertically provided in the first slide groove 10, and a first spring 9 is sleeved on the guide rod 8. The slider 11 and the abutment plate 7 are both vertically slidably sleeved on the guide rod 8. The two ends of the first spring 9 are respectively fixedly connected to the slider 11 and the top wall of the first slide groove 10. Specifically, the guide rod 8 plays a guiding role, so that the moving direction of the splint 13 can only be vertical linear movement, and the cooperation of the first spring 9 and the guide rod 8 can play a buffering role to prevent the splint 13 from falling instantly and damaging the rotor.

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

[0033] As a preferred technical solution, the transmission assembly includes a connecting bracket 15, a worm wheel 20, a worm 21 meshing with the worm wheel 20, a turntable 22, a screw 23, a sliding bracket 24, a rack 17 and a gear 18 meshing with the rack 17. The two ends of the connecting bracket 15 are fixedly connected to the splint 13 and the rack 17 respectively, and the gear 18 is rotatably connected to the machine 2. A connecting shaft 19 is provided between the gear 18 and the worm wheel 20. The worm 21 is vertically rotatably connected to the machine 2. The two ends of the turntable 22 are fixedly connected to the worm 21 and the screw 23 respectively. The sliding bracket 24 is screwed to the screw 23. The sliding bracket 24 is vertically slidably connected to the machine 2. The winding shaft 25 is rotatably connected to the sliding bracket 24. Specifically, the splint 13 drives the rack 17 to move through the connecting bracket 15. The meshing transmission between the rack 17 and the gear 18 makes the gear 18 drive the worm wheel 20 to rotate through the connecting shaft 19. The meshing transmission of the worm gear 20 and the worm 21 causes the worm 21 to drive the turntable 22 to rotate, so that the turntable 22 drives the screw 23 to rotate. A third slide slot 34 is vertically opened in the machine table 2, and the sliding bracket 24 is slidably connected to the third slide slot 34. Since the third slide slot 34 limits the circumferential rotation of the sliding bracket 24, the spiral transmission of the screw 23 drives the sliding bracket 24 to slide vertically, and the sliding bracket 24 drives the winding shaft 25 to move vertically, 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 changes in the center of the winding shaft 25 of rotors of different lengths, saving the time of replacing different parts for adapting to different rotors, and improving the winding efficiency and adaptability of the overall device. Preferably, a motor is provided on the side of the sliding bracket 24 away from the winding head 30, and the output end of the motor is coaxially fixedly connected to the winding shaft 25 for driving the winding shaft 25 to rotate for the winding operation.

[0034] As a preferred technical solution, the linkage assembly includes an articulated rod 29, a table 26 and a baffle 35. The baffle 35 is arranged in the machine 2, and the table 26 is slidably sleeved on the winding shaft 25. The bottom of the baffle 35 slides and abuts against the peripheral side of the table 26. The two ends of the articulated rod 29 are respectively hinged to the winding head 30 and the table 26. Specifically, in the process of the winding shaft 25 moving vertically with the sliding bracket 24, the table 26 slides and abuts against the baffle 35, and the table 26 slides horizontally along the length direction of the winding shaft 25. The winding head 30 is pushed to slide in the clamping plate 13 through the articulated shaft, which can adapt to the winding radius of rotors of different lengths, thereby improving the winding efficiency and adaptability of the overall device.

[0035] As a preferred technical solution, a sliding hole 33 is provided in the connecting plate 31, and a limiting rod 32 is provided 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 slipping out and falling.

[0036] As a preferred technical solution, a telescopic rod 27 is provided between the truncated table 26 and the connecting plate 31, and a second spring 28 is sleeved on the telescopic rod 27. Specifically, when the winding shaft 25 drives the connecting plate 31 to rotate to achieve winding, the truncated table 26 rotates synchronously through the connection of the telescopic rod 27, and the action force of the second spring 28 and the action force of the baffle 35 can prevent the truncated table 26 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 winding by the winding head 30.

[0038] As a preferred technical solution, a winding seat 14 is provided on the clamping plate 13, specifically, for providing the winding head 30 with the copper wire required for winding.

[0039] When the rotor is under the clamping plate 13, the mechanical clamping plate 6 releases the clamping force and moves out with the pushing block 7. The clamping plate 13 is moved downward by the self-gravity of the abutment block, the slider 11 and the clamping plate 13, so that the clamping plate 13 can clamp rotors of different lengths, thereby improving the adaptability of the overall device. The clamping plate 13 drives the rack 17 to move through the connecting bracket 15. The meshing transmission between the rack 17 and the gear 18 makes the gear 18 drive the worm wheel 20 to rotate through the connecting shaft 19. The meshing transmission between the worm wheel 20 and the worm 21 makes the worm 21 drive the turntable 22 to rotate. The turntable 22 drives the screw 23 to rotate, and a third slide groove 34 is vertically opened in the machine table 2, and the sliding bracket 24 is slidably connected in the third slide groove 34. Since the third slide groove 34 limits the circumferential rotation of the sliding bracket 24, the sliding bracket 24 is driven to slide vertically by the spiral transmission of the screw 23, and the sliding bracket 24 drives the winding shaft 25 to move vertically, 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 changes in the center of the winding shaft 25 of rotors with different lengths, saving time for replacing different parts for adapting to different rotors, and improving the winding efficiency and adaptability of the overall device. At the same time, in the process of the winding shaft 25 moving vertically with the sliding bracket 24, the round table 26 slides against the baffle 35, and the round table 26 slides horizontally along the length direction of the winding shaft 25, and pushes the winding head 30 to slide in the clamping plate 13 through the hinge shaft, which can adapt to the winding radius of rotors with different lengths, and improve the winding efficiency and adaptability of the overall device.

[0040] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various 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.
