[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0032] Example 1

[0033] like Figure 1 As shown, the motor rotor winding feeding device of this embodiment includes a frame 1 and a horizontally arranged workbench 3. Two bases 4 are rotatably fitted in the workbench 3. A clamping member 2 is connected to the upper end of the base 4. A rectangular groove 406 is opened at the lower end of the base 4. A plate 9 is matched in the rectangular groove 406. A telescopic member 8 is provided below the plate 9 to drive the plate 9 to move so that the plate 9 can be inserted into or disengaged from the rectangular groove 406.

[0034] The lower end face of the workbench 3 is connected to a gear 5, which meshes with a gear 6. A first driving component is provided between the gear 6 and the frame 1 and is connected through the first driving component. The frame 1 is connected to a longitudinally arranged second driving component 7, and the output end of the second driving component 7 is connected to a telescopic component 8.

[0035] In this case, when the first driving component is powered on, it drives the gear 6 to rotate. The gear 6 meshes with the gear tooth 5. When the gear 6 rotates clockwise, it drives the worktable 3 to move to the right and drives the left clamping member 2 to move above the plate 9. When the gear 6 rotates counterclockwise, it drives the worktable 3 to move to the left and drives the right clamping member 2 to move above the plate 9.

[0036] The rotor shaft of the rotor to be wound is fixed inside the clamping piece 2, the base 4 corresponding to the clamping piece 2 is moved to the upper side of the plate body 9 by the movement of the workbench 3, the plate body 9 is inserted into the inside of the rectangular groove 406 of the corresponding base 4 by the telescopic piece 8, under the cooperation of the plate body 9 and the rectangular groove 406, the second driving piece 7 is energized and started, and the winding operation is completed by the cooperation of the telescopic piece 8, the plate body 9, the base 4, the clamping piece 2, and the rotor. After the winding operation is completed, the plate body 9 is separated from the inside of the rectangular groove 406 by the telescopic piece 8, and the clamping piece 2 is moved to one side of the plate body 9 by the workbench 3, and the material taking and feeding operations are performed.

[0037] The two clamping pieces 2 are used alternately, and when one clamping piece 2 is winding, the other clamping piece 2 that has completed winding is taken and fed. The motor rotor winding and feeding device does not need to stop and take out the rotor, improves the continuity of the rotor winding operation, and saves the operation time.

[0038] In order to improve the stability of the position of the workbench 3, as shown in Figure 1 , the upper and lower end faces of the workbench 3 are connected with gear teeth 5, and the gear teeth 5 of the upper and lower end faces are engaged with the settings of the gears 6. The lower gear 6 is a driving gear, and the upper gear 6 is a driven gear. When the workbench 3 moves, the rotating directions of the two gears 6 on the upper and lower sides are opposite.

[0039] The settings of the gears 6 provide power for the movement of the workbench 3, support the workbench 3, limit the position of the workbench 3, improve the stability of the position of the workbench 3, and prevent the winding part from moving the position of the rotor when winding the rotor.

[0040] As shown in Figure 1 , Figure 2 , the base 4 includes a first tube body 401 and a column body 402. The first tube body 401 is connected with the workbench 3, and the first tube body 401 and the column body 402 are rotatably connected through the bearing 403. The insertion rectangular groove 406 is arranged at the lower end of the column body 402. The rotatable connection between the first tube body 401 and the column body 402 through the bearing 403 meets the requirement of rotating the base 4 to drive the clamping piece 2;

[0041] The upper end inside of the first tube body 401 is connected with two oppositely arranged first permanent magnets 404, and the upper end of the column body 402 is connected with a second permanent magnet 405 matched with the first permanent magnet 404.

[0042] The first permanent magnet 404 and the second permanent magnet 405 are attracted to each other, and the column body 402 is driven to rotate, and the first permanent magnet 404 and the second permanent magnet 405 are opposite to each other, and the rectangular groove 406 is rotated to a machining position matched with the plate body 9; the first permanent magnet 404 and the second permanent magnet 405 are arranged to assist the column body 402 to rotate and reset, so that the column body 402 is not deviated when the rotor is clamped or removed, and the plate body 9 can be smoothly inserted into the inside of the rectangular groove 406.

[0043] As shown in Figure 1 , Figure 3 , the telescopic part 8 comprises a first cylinder 801 connected with the output end of the second driving part 7, a long rod 803 movably inserted into the first cylinder 801, a first spring 802 connected between the end of the long rod 803 inside the first cylinder 801 and the inner bottom wall of the first cylinder 801, and the plate body 9 connected with the end of the long rod 803 outside the first cylinder 801; the telescopic part 8 further comprises an electromagnet 805 and an armature 806, the electromagnet 805 is fixedly embedded in the through hole of the plate body 9, and the armature 806 is arranged in the rectangular groove 406.

[0044] The arrangement of the telescopic part 8 drives the plate body 9 to move upwards to complete the operation of being inserted into the inside of the rectangular groove 406, and drives the plate body 9 to move downwards to complete the operation of being separated from the rectangular groove 406; after the base 4 is moved to the upper side of the plate body 9, the electromagnet 805 is electrified to generate magnetism and attract the armature 806, so that the plate body 9 is inserted into the inside of the rectangular groove 406, at this time, the first spring 802 is stretched, after the rotor winding is completed, the electromagnet 805 is de-energized, under the action of the first spring 802, the long rod 803 and the plate body 9 are separated from the rectangular groove 406, and the base 4 is moved to the side of the plate body 9.

[0045] The long rod 803 is connected with a fin plate 804 inside the first cylinder 801, the fin plate 804 movably penetrates the limiting groove of the first cylinder 801, and the fin plate 804 and the limiting groove are in sliding fit when the long rod 803 moves up and down in the inside of the first cylinder 801, so that the fin plate 804 limits the circumferential position of the long rod 803, and prevents the long rod 803 from driving the plate body 9 to rotate.

[0046] As shown in Figure 1 , Figure 4 , the workbench 3 is connected with a supporting part 10 away from the gear teeth 5; the supporting part 10 comprises a supporting pipe 1001 connected with the frame body 1 and a supporting rod 1002 connected with the workbench 3, and the supporting rod 1002 is inserted into the inside of the supporting pipe 1001 and in sliding fit with the supporting pipe 1001. The arrangement of the supporting part 10 supports the right end of the workbench 3, and improves the stability of the position of the workbench 3.

[0047] The support pipe 1001 is provided with an A end and a B end, and the support rod 1002 is connected with the block 1003 at one end inside the support pipe 1001. When the left clamping piece 2 is above the plate body 9, the block 1003 is in contact with the B end. When the right clamping piece 2 is above the plate body 9, the block 1003 is in contact with the A end. The block 1003 is in contact with the A end and the B end to limit the maximum moving distance of the workbench 3 in the left-right direction, thereby preventing over-movement.

[0048] As shown in Figure 1 , Figure 5 , the clamping piece 2 comprises a second cylinder 201 connected with the column 402. The outer wall of the second cylinder 201 is threadedly connected with a second pipe 202. The second pipe 202 and the second cylinder 201 form a cavity 203 with a right-angled triangle cross section. The inner wall of the cavity 203 is slidingly connected with at least three extrusion rods 204 which are equidistantly and annularly distributed. One end of the extrusion rod 204 is movably penetrated through the side wall of the second cylinder 201 and connected with a clamping plate 205.

[0049] The rotor shaft to be wound is inserted between the clamping plates 205. The second pipe 202 is rotated and moved downward. The inner wall of the cavity 203 extrudes the extrusion rods 204, drives the clamping plates 205 to move toward the rotor shaft, and clamps and fixes the rotor shaft by the clamping plates 205. The second pipe 202 extrudes the extrusion rods 204 at the same time, drives the clamping plates 205 to clamp and fix the rotor shaft, so as to fix the rotor at the middle position of the clamping piece 2 and improve the accuracy of the winding operation.

[0050] The extrusion rod 204 is sleeved with a second spring 206. The two ends of the second spring 206 are connected with the inner wall of the second cylinder 201 and the clamping plate 205, respectively. When the clamping plate 205 moves toward the rotor shaft, the second spring 206 is stretched. The second spring 206 is arranged to assist the clamping plate 205 to reset and improve the convenience when the rotor shaft is inserted into the clamping piece 2.
