[0002] The commutator is a key component of the drive motor. Its technical performance indicators and quality directly affect the overall performance of the micromotor. The commutator is usually installed on the rotor of the motor and rotates synchronously with the rotor. The function of the micromotor commutator is to change the current direction and magnetic field distribution in the motor winding, so that the motor can run smoothly and normally;

DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-9A rotor commutator assembly tool for motor production includes an assembly table 1, a rotating disk 10 is rotatably arranged on the assembly table 1, a fixing ring 21 is fixedly arranged on the assembly table 1, the fixing ring 21 is rotatably connected to the rotating disk 10, a convex rod 22 is fixedly arranged on the rotating disk 10, a first sleeve 23 and a second sleeve 26 are rotatably arranged on the convex rod 22, a first slider 25 and a second slider 271 are slidably arranged on the fixing ring 21, a first rod core 24 is slidably arranged in the first sleeve 23, a second rod core 27 is slidably arranged in the second sleeve 26, the first rod core 24 is rotatably connected to the first slider 25, the second rod core 27 is rotatably connected to the second slider 271, and a first slider 25 is fixedly arranged on the first slider 25. A push rod 32 is provided for pressing the commutator onto the rotor core, and a detection rod 272 for removing unqualified commutators is fixedly provided on the second slider 271; a driving mechanism, the driving mechanism includes a driving disk 12 rotatably arranged in the assembly table 1, the driving disk 12 is fixedly connected to the rotating disk 10, and a driven disk 15 cooperating with the driving disk 12 is rotatably arranged in the assembly table 1. When the driving disk 12 rotates, the detection rod 272 is pushed by the second rod core 27 to remove the unqualified commutator, and the qualified commutator is pressed onto the rotor core through the first rod core 24, and the station switching is performed; the convex rod 22 is fixedly arranged along the radial direction of the rotating disk 10 and close to the outer peripheral surface of the rotating disk 10, and the first rod core 2 Two first springs 28 are fixedly arranged between the first sleeve 23 and the inner wall of the first sleeve 23, and two second springs 34 are also fixedly arranged between the second rod core 27 and the inner wall of the second sleeve 26. By setting the first sleeve 23 and the first rod core 24, the second sleeve 26 and the second rod core 27 to be retractable, the volume of the device can be reduced. The end of the first rod core 24 away from the protruding rod 22 is rotatably connected to the first slider 25, and the end of the second rod core 27 away from the protruding rod 22 is rotatably connected to the second slider 271. The push rod 32 is arranged on the side of the first slider 25 away from the protruding rod 22. The protruding rod 22 has a groove 35 for the shaft of the rotor core to extend into. The detection rod 272 is arranged at the side of the second slider 271 away from the protruding rod 2 2, a servo motor (not shown in the figure) is fixedly arranged in the assembly table 1, and a rotating shaft 11 is fixedly arranged at the output end of the servo motor. The rotating shaft 11 is fixedly connected with the rotating disk 10 and the driving disk 12 and is coaxially arranged. The rotating disk 10 is above the driving disk 12. When in use, the rotating shaft 11, the driving disk 12 and the rotating disk 10 are rotated by the servo motor. When the rotating disk 10 rotates, the protruding rod 22 is driven to make a circular motion around the axis of the rotating disk 10, so that the first sleeve 23 and the second sleeve 26 are rotatably connected to the protruding rod 22 to make a circular motion around the axis of the rotating disk 10, so that the first slider 25 and the second slider 271 make a reciprocating linear motion on the fixed ring 21, as shown in FIG. Figure 4As shown, the rotating disk 10 rotates counterclockwise. When the protruding rod 22 rotates to the rightmost side, the push rod 32 shrinks in the fixed ring 21, and the first slider 25 is on the side close to the rotating disk 10. At this time, the two first springs 28 in the first sleeve 23 extend, and the slider pushes the detection rod 272 to extend out of the fixed ring 21 and insert into the commutator inner ring. The size of the detection rod 272 is adapted to the size of the qualified commutator inner ring. When the size of the commutator inner ring is too small and the interference fit of the rotor core is too large, the detection rod 272 cannot be inserted into the commutator inner ring. When the coaxiality of the commutator inner ring is different, the end of the detection rod 272 will abut against the commutator inner ring, so that it cannot pass through the commutator inner ring normally, and then the commutator with an inner ring that is too small or with different coaxiality will be moved and fall from the assembly table 1, completing the removal of unqualified commutators to avoid damage to the rotor core during press-fitting. If it is a qualified commutator, the detection rod 272 will pass through the commutator inner ring, and the steering gear will not move. As the rotating disk 10 rotates counterclockwise, the protruding rod 22 moves from the rightmost side to the uppermost side. During rotation, the second slider 271 is pulled toward the side close to the rotating disk 10 by the second spring 34. At this time, the detection rod 272 is pulled out from the commutator, and the first spring 28 in the first sleeve 23 retracts. When the protrusion 241 rotates to the uppermost end, the second slider 271 is located at the side of the fixed ring 21 close to the rotating disk 10. At this time, the springs in the first sleeve 23 and the second sleeve 26 are both in a normal state. As the rotating disk 10 continues to rotate, the protrusion 22 rotates from the uppermost side to the leftmost side. At this time, the detection rod 272 is pulled out from the commutator, and the first spring 28 in the first sleeve 23 retracts. 23 and the first rod core 24 push the first slider 25 to move away from the rotating disk 10. At this time, the first slider 25 pushes the push rod 32 to move and press the qualified commutator onto the rotor core. As the protruding rod 22 moves from the leftmost side to the bottommost side, when the protruding rod 22 rotates from the bottommost side to the rightmost side, the driving disk 12 drives the driven disk 15 to rotate 45 degrees, that is, the rotating disk 10 rotates 360 degrees, and the driven disk 15 rotates 45 degrees. At this time, the workpieces at the inspection station and the assembly station move forward to the next step.

[0031] Furthermore, a rotating ring 31 is rotatably provided on the assembly table 1, and the rotating ring 31 is rotatably connected to the fixed ring 21. Four first clamps 36 are fixedly provided on the rotating ring 31, and a second clamp 37 is rotatably provided on each first clamp 36; the commutator is clamped by the first clamp 36 and the second clamp 37, and a torsion spring is fixedly provided one by one between each first clamp 36 and the second clamp 37. In the initial state, the second clamp 37 on the first clamp 36 is in an open state, so as to facilitate preventing the commutator from being on the first clamp 36. When the commutator needs to be inspected and pressed, the second clamp 37 is closed on the corresponding first clamp 36 to limit the commutator.

[0032] Further, a fixed arc plate 2 is fixedly arranged on the assembly table 1, and the fixed arc plate 2 is fixedly connected to the fixed ring 21; the fixed arc plate 2 is used to fix the fixed ring 21, such as Figure 1 As shown, a first loading robot 3 for loading the commutator and a unloading robot 4 for taking out the pressed-together rotating shaft 11 iron core and the commutator are fixedly arranged below the assembly platform 1, and a second loading robot 5 for loading the rotor iron core is fixedly arranged on the upper side of the assembly platform 1. The first loading robot 3, the second loading robot 5, and the unloading robot 4 are all prior arts, and no further elaboration is required here. The fixed arc plate 2 has a notch on one side close to the first loading robot 3, combined with Figure 1 , when the first clamping plate 36 and the corresponding second clamping plate 37 move perpendicular to the lower side of the assembly table 1 and close to the first loading robot 3, the second clamping plate 37 is in an open state. At this time, the assembled rotor core and commutator are removed by the unloading robot 4 to complete the unloading. Then, the commutator is placed on the first clamping plate 36 by the first loading robot 3. As the rotating disk 10 rotates, the rotating ring 31 also rotates intermittently. When the first clamping plate 36 after the commutator is installed rotates counterclockwise to the fixed arc plate 2, the first clamping plate 36 and the second clamping plate 37 are closed by the abutment of the second clamping plate 37 corresponding to the fixed arc plate 2, thereby clamping the commutator. When the second clamping plate 37 is separated from the fixed arc plate 2, The second clamping plate 37 is automatically opened by the torsion spring, so as to facilitate the loading of the commutator. When the first clamping plate 36 and the second clamping plate 37 move counterclockwise to the left side closest to the assembly table 1, the commutator is detected by the detection rod 272. When the first clamping plate 36 and the second clamping plate 37 move counterclockwise to the upper side closest to the assembly table 1, the rotor core is loaded. When the first clamping plate 36 and the second clamping plate 37 move counterclockwise to the right side closest to the assembly table 1, the commutator is pressed onto the rotor core by the push rod 32. When the first clamping plate 36 and the second clamping plate 37 move counterclockwise to the lower side closest to the assembly table 1, the rotor core of the installed commutator is removed and a new commutator is placed on the first clamping plate 36.

[0033] Specifically, a bearing ring 41 is rotatably provided on the assembly platform 1, the bearing ring 41 is rotatably connected to the rotating ring 31, a bearing plate 42 is fixedly provided on the bearing ring 41, and a baffle 43 is fixedly provided on the assembly platform 1; Figure 1There are four bearing plates 42, which are evenly arranged on the bearing ring 41. The bearing plates 42 are used to place the rotor core. After the second loading robot 5 places the rotor core on the bearing plate 42, as the rotating disk 10 rotates one circle, the rotating ring 31 is driven by the driven disk 15 to rotate 45 degrees. When the rotating ring 31 rotates, the bearing ring 41 is driven to rotate 45 degrees at the same time, so that the commutator that has been tested and the bearing plate 42 with the rotor core installed are moved to the side of the assembly platform 1 close to the push rod 32. At this time, the commutator, the push rod 32 and the rotor core are coaxially aligned. At this time, the push rod 32 is retracted in the fixed disk, and the baffle 43 is at the far right of the assembly platform 1. When the commutator, the push rod 32 and the rotor core are coaxially aligned, the baffle 43 is behind the bearing plate 42 close to the push rod 32. As the rotating disk 10 rotates, the push rod 32 moves in the direction close to the baffle 43, so that the commutator is pressed onto the rotor core to complete the assembly of the commutator.

[0034] In another embodiment of the present invention, four feeding slots 312 are symmetrically provided on the rotating ring 31; when the commutator clamped in the first clamping plate 36 and the second clamping plate 37 moves to be coaxially aligned with the detection rod 272, the commutator does not move. At this time, the rotating disk 10 needs to rotate one circle to make the commutator rotate 45 degrees around the axis of the rotating disk 10 again. When the rotating disk 10 rotates, the detection rod 272 is extended toward the commutator, and the inner wall surfaces of the first clamping plate 36 and the second clamping plate 37 are both The frosting treatment can increase friction. When the inner diameter of the commutator is small, the detection rod 272 will push the commutator to move away from one end of the bearing plate 42, thereby withdrawing the commutator from the first clamping plate 36 and the second clamping plate 37. When the unqualified commutator moves out of the first clamping plate 36 and the second clamping plate 37, it falls from the rotating ring 31 through the discharge chute 312, thereby completing the removal of the unqualified commutator. There are also four first clamping plates 36 on the rotating ring 31, but they are aligned one by one with each discharge chute 312.

[0035] Specifically, a card block 38 is slidably disposed in each second clamping plate 37, and a third spring 39 is disposed between each clamping plate 38 and each first clamping plate 36 in a one-to-one correspondence; the number of the third springs 39 on each clamping plate 38 is two and they are stacked and disposed on both sides of the card block 38. When the commutator is placed on the first clamping plate 36, the second clamping plate 37 is closed on the first clamping plate 36, and the card block 38 is pressed upward through the commutator. At this time, the card block 38 shrinks into the second clamping plate 37, and the card block 38 abuts against the commutator. When the detection rod 272 is inserted into a commutator with different coaxiality, it will abut against the inner wall of the commutator and push the commutator to move. When the commutator moves out from the first clamping plate 36 and the second clamping plate 37, the blocking block 38 is moved downward by the third spring 39. Since the detection rod 272 is inserted into the inner ring of the commutator at this time, when the detection rod 272 moves back into the fixed disk, the downward moving blocking block 38 abuts against the end of the commutator, thereby pushing the commutator out of the detection rod 272, and the commutator falls into the discharge trough 312.

[0036] In another embodiment of the present invention: a limit plate 13 is fixedly arranged on the driving plate 12, a driving rod 14 is fixedly arranged on the driving plate 12, and four driving grooves 17 are opened on the driven plate 15; the four driving grooves 17 are symmetrically arranged, and four limit grooves 16 that can fit with the outer rear surface of the limit plate 13 are symmetrically opened on the driven plate 15. When the driving plate 12 rotates, it drives the driving rod 14 to rotate around the axis of the rotating shaft 11. When the driving rod 14 rotates to the driving groove 17, it will extend into the driving groove 17. As the driving plate 12 continues to rotate, the driven plate 15 is driven to rotate 45 degrees through the cooperation of the driving rod 14 and the inner wall of the driving groove 17. After the driven plate 15 rotates 45 degrees, the limit grooves 16 fit with the outer peripheral surface of the limit plate 13 again, thereby preventing the driven plate 15 from accidentally rotating, making it impossible to align the rotor core and the commutator.

[0037] Specifically, a gear ring 19 is rotatably provided on the limit plate 13, a gear 18 meshing with the gear ring 19 is fixedly provided on the driven plate 15, four connecting rods 44 are symmetrically fixed on the gear ring 19, and each connecting rod 44 is fixedly connected to the rotating ring 31; when the driving plate 12 drives the driven ring to rotate through the cooperation of the driving rod 14 and the driving groove 17, the driven ring drives the gear 18 to rotate, and the gear 18 drives the gear ring 19 to rotate. The transmission ratio of the gear 18 to the gear ring 19 is one to one. When the gear ring 19 rotates, the rotating ring 31 is driven to rotate through the connecting rods 44, so that the rotating ring 31 drives the commutator to switch the processing station, thereby realizing the loading and unloading, detection and assembly of the commutator.

[0038] In another embodiment of the present invention, four abutment blocks 48 are fixedly provided on the carrying ring 41, and a movable plate 45 is slidably provided at one end of each connecting rod 44 away from the gear ring 19, and an avoidance groove 451 is opened on each movable plate 45; the movable plate 45 is pushed so that the movable plate 45 can abut against the abutment block 48 when passing through the abutment block 48, so that when the rotating ring 31 rotates, the carrying ring 41 can be driven to rotate through the abutment block 48, so that the rotor core and the commutator rotate together to switch the work station, and when the unqualified commutator is pushed down the discharge chute 312 at the detection rod 272, with the rotation of the rotating ring 31 and the carrying ring 41, the empty first clamping plate 36 and the second clamping plate 37 move to the push rod 32, and at this time the push rod 32 moves in the direction close to the first clamping plate 36. Since there is no commutator in the first clamping plate 36 and the second clamping plate 37, the push rod 32 extends into the first clamping plate 36 and the second clamping plate 37 at this time, pushing the movable plate 45 in the direction away from the gear ring 19, so that the avoidance groove 451 is aligned with the abutment block 48. At this time, the rotating ring 31 rotates 45 degrees and the load-bearing ring 41 does not rotate, and the abutment block 48 will pass through the avoidance groove 451, thereby preventing the rotor core without commutator assembled from moving to the unloading robot 4 and being taken out. As the rotating ring 31 rotates, the first clamping plate 36 holding the qualified commutator moves to the rotor core to be assembled with the commutator, thereby realizing automatic replacement after automatic removal of unqualified products.

[0039] Specifically, four slide grooves 311 are provided on the rotating ring 31, and an abutment rod 452 is slidably provided in each slide groove 311, and each abutment rod 452 is fixedly connected with each movable plate 45 in a one-to-one correspondence, a second spring 34 is fixedly provided between the first slider 25 and the push rod 32, and an abutment plate 33 is fixedly provided at one end of the push rod 32 close to the first slider 25, and an inclined plate 47 and a triangular plate 46 are fixedly provided in the assembly table 1;When the commutator axis is aligned with the axis of the detection rod 272, there is no rotor core on the carrier plate 42 on the carrier ring 41. When the commutator detection is completed, the rotor core is placed on the carrier plate 42 by the second loading robot 5. At this time, the axis of the rotor core is above the corresponding avoidance groove 451. In the initial state, the avoidance groove 451 on each movable plate 45 is aligned with the abutment block 48. At this time, the rotation of the rotating ring 31 will not drive the carrier ring 41 to rotate. When the first clamping plate 36 and the second clamping plate 37 are about to move to the push rod 32, the movable plate 45 at the bottom of the rotating ring 31 abuts against the inclined plate 47, and the movable plate 45 is pushed to move by the inclined plate 47, so that the avoidance groove 451 of the movable plate 45 is staggered with the abutment block 48. When the first clamping plate 36 and the second clamping plate 37 are about to move to the push rod 32, the movable plate 45 at the bottom of the rotating ring 31 abuts against the inclined plate 47. When the plate 36 and the second clamping plate 37 move to the push rod 32, the moving plate 45 just abuts against the abutment block 48 and separates from the inclined plate 47. The rotating disk 10 that continues to rotate drives the push rod 32 to move in the direction close to the first clamping plate 36 and the second clamping plate 37. If there is a commutator in the first clamping plate 36 and the second clamping plate 37 at this time, the push rod 32 pushes the commutator to move toward the axis of the rotor core and inserts the end of the axis into the inner ring of the commutator. The rear of the rotor core abuts against the baffle 43, and the second spring 34 is gradually compressed. As the first slider 25 moves, the first slider 25 pushes the push rod 32 to move in the direction close to the baffle 43, so that the axis of the rotor core is inserted into the inner ring of the commutator and the installation is completed. Due to the abutment of the commutator, the push rod 32 will not be completely The first clamping plate 36 and the second clamping plate 37 are fully extended into the first clamping plate 36 and the second clamping plate 37, so that the abutment plate 33 will not abut against the abutment rod 452, and the movable plate 45 remains in a state of abutting against the corresponding abutment block 48. At this time, the rotation of the rotating ring 31 can push the abutment block 48 through the movable plate 45 and drive the bearing ring 41 to rotate. A fixed rod 453 is fixedly arranged at the bottom of the movable plate 45. The fixed rod 453 is slidably connected with the connecting rod 44 and extends out from the bottom of the connecting rod 44. When the rotating ring 31 drives the bearing ring 41 to rotate 45 degrees, the fixed rod 453 is pushed through the triangular plate 46 and drives the movable plate 45 to move, so that the avoidance groove 451 on the movable plate 45 gradually coincides with the abutment block 48. When the bearing ring 41 and the rotating ring 31 rotate 45 degrees, the avoidance groove 451 is not rotated. 51 is just aligned with the abutment block 48, that is, the moving plate 45 can only drive the abutment block 48 and the carrying ring 41 to rotate at the push rod 32, so that whether the carrying ring 41 follows the rotating ring 31 depends on whether there is a commutator in the first clamping plate 36 at the push rod 32. When there is no commutator in the first clamping plate 36 and the second clamping plate 37 at the push rod 32, the first slider 25 pushes the push rod 32 to move, and the push rod 32 will fully extend into the first clamping plate 36. At this time, the abutment plate 33 abuts against the abutment rod 452, thereby pushing the moving plate 45 to move, so that the avoidance groove 451 of the moving plate 45 is aligned with the abutment block 48. At this time, the rotation of the rotating ring 31 will not drive the carrying ring 41 to rotate, so that the rotor core without a commutator is waiting for assembly in situ. ;
