Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to an automatic bending device for excitation motor windings. Background Technology

[0002] In the field of electric motor manufacturing, the winding bending process of the excitation motor is of paramount importance as a key component. The quality of the winding bending directly affects the performance, efficiency, and reliability of the motor.

[0003] Currently, traditional methods of bending exciter motor windings mostly rely on manual operation. Workers need to fix the exciter motor to the tooling and use a bending hook to plastically shape the ends of the windings. Moreover, only one wire can be processed at a time.

[0004] The existing technical solutions mentioned above have the following drawbacks: relying solely on manual bending of the wires at the winding ends with a bending hook cannot meet the needs of mass production, and manual force is difficult to ensure consistent angles, which can easily lead to uneven winding deformation and affect the electromagnetic performance of the motor. Utility Model Content

[0005] The purpose of this invention is to provide an automatic bending device for excitation motor windings to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An automatic bending device for excitation motor windings, comprising:

[0008] A vertical plate, with a bottom plate extending to the left from the bottom left side, and a through hole extending from left to right in the middle of the right side of the vertical plate, and a guide post assembly fixedly installed on the right side of the vertical plate.

[0009] A servo motor is fixedly mounted on the top of the base plate. Both ends of the servo motor pass through and extend to the outside of the through hole. The outer wall of the servo motor is fixedly connected to the vertical plate. A bending die is provided at the output end of the servo motor.

[0010] A sliding device is slidably mounted on the guide column assembly, and the sliding device is used to house the excitation motor.

[0011] A clamping device is slidably mounted on the guide post assembly. The clamping devices are spaced apart at the right end of the sliding device and are used to clamp the sliding device.

[0012] A hydraulic cylinder is provided, located at the bottom right side of the vertical plate. The hydraulic cylinder includes a fixed part and a movable part. The fixed part of the hydraulic cylinder is fixedly connected to the right side of the vertical plate. The hydraulic cylinder is used to drive the pressing device to move.

[0013] By adopting the above technical solution, the operator places the exciter motor in the sliding device, then moves the sliding device closer to the vertical plate, and then starts the hydraulic cylinder. The hydraulic cylinder drives the clamping device to move to the left, so that the clamping device clamps the sliding device to the left and prevents the sliding device from shifting. This allows the winding end of the exciter motor to be fully inserted into the bending die. Finally, the servo motor is started, so that the bending die applies the bending force to the winding, completing the automatic bending of the exciter motor winding.

[0014] In a further embodiment, the guide post assembly includes a first guide post and a second guide post, the first guide post and the second guide post are arranged in parallel, and the left ends of the first guide post and the second guide post are fixedly connected to the top right side of the vertical plate.

[0015] By adopting the above technical solution, the first guide post and the second guide post provide stable support and guidance for the sliding device and the clamping device.

[0016] In a further embodiment, the bending die is a circular plate, and a through hole is provided at the center of the circular plate. The circular plate is sleeved on the output shaft of the servo motor, and the output shaft of the servo motor and the circular plate are fixedly connected. An integrally formed first cylinder is provided at the center of the right side of the circular plate. A left-facing clearance groove is provided at the center of the right side of the first cylinder. Multiple left-facing circular grooves are provided at equal intervals on the right periphery of the first cylinder.

[0017] In a further embodiment, the sliding device includes:

[0018] The first upright plate has two through holes on its right side. A first guide sleeve is inserted into the first hole and is fixedly connected to the inner wall of the first hole.

[0019] The first upright plate has a second circular hole that runs through the left and right sides at the center of the right side. The second cylinder passes through the second circular hole, and the right end of the second cylinder extends to the outside of the second circular hole. The left side of the second cylinder has a receiving groove facing to the right.

[0020] By adopting the above technical solution, the first cylinder is inserted into the receiving groove, so that the windings of the excitation motor placed in the receiving groove are respectively inserted into the circular groove, and the other components of the excitation motor are inserted into the clearance groove, so as to prevent the bending operation of the excitation motor windings from being affected.

[0021] In a further embodiment, the clamping device includes a second upright plate and a crossbar. The right side of the second upright plate is provided with two through-holes. A second guide sleeve is inserted into the second hole. The second guide sleeve and the inner wall of the second hole are fixedly connected. The center position of the right side of the second upright plate is provided with a through-hole. The left end of the crossbar passes through from right to left and extends to the outside of the third hole. The right end of the crossbar is fixedly connected to the inner wall of the third hole. The right end of the movable part of the hydraulic cylinder is fixedly connected to the left side of the second upright plate.

[0022] In a further embodiment, a manual switch for controlling the hydraulic cylinder is provided on the top of the first upright plate.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. By placing the exciter motor inside the sliding device, then moving the sliding device closer to the vertical plate, and then activating the hydraulic cylinder, the hydraulic cylinder drives the clamping device to move to the left, thereby clamping the clamping device to the left against the sliding device and preventing the sliding device from shifting, so that the winding end of the exciter motor is fully inserted into the bending die. Finally, the servo motor is activated, thereby applying the bending force to the bending die, which can achieve the effect of automatically bending the exciter motor winding.

[0033] The guide post assembly 3 includes a first guide post 31 and a second guide post 32, which are arranged in parallel. The first guide post 31 is spaced apart at the rear end of the second guide post 32. The left ends of the first guide post 31 and the second guide post 32 are fixedly connected to the top right side of the vertical plate 1. The bending die 5 is a circular plate with a through hole at its center. The circular plate is fitted onto the output shaft of the servo motor 4, and the output shaft of the servo motor 4 is fixedly connected to the circular plate. An integrally formed first cylinder is located at the center right side of the circular plate. A left-facing clearance groove is located at the center right side of the first cylinder. Multiple left-facing circular grooves are evenly spaced along the right periphery of the first cylinder. The diameter of the multiple circular grooves is the same as the diameter of a single conductor of the excitation motor winding, and the axis of the conductor is on a horizontal straight line with the axis of the corresponding circular groove. The sliding device 6 includes a first vertical plate 61 and a second cylinder 62. Two through holes are located on the right side of the first vertical plate 61, and a first guide post is inserted through each hole. The sleeve 63 and guide sleeve 63 are fixedly connected to the inner wall of the first circular hole. A second circular hole is provided at the center of the right side of the first vertical plate 61, which is open from left to right. The second cylinder 62 passes through the second circular hole, and the right end of the second cylinder 62 extends to the outside of the second circular hole. A right-facing receiving groove is provided on the left side of the second cylinder 62. The pressing device 7 includes a second vertical plate 71 and a crossbar 72. Two second circular holes are provided on the right side of the second vertical plate 71, and a second guide sleeve 73 passes through the second circular hole. 73 is fixedly connected to the inner wall of the second circular hole. A third circular hole that runs through the left and right sides is provided at the center of the right side of the second vertical plate 71.

[0035] Specific implementation process: Place the exciter motor to be bent into the receiving groove of the second cylinder 62 of the sliding device 6, ensuring that the winding part of the exciter motor faces the bending die 5; then the operator moves the sliding device 6 to the left, so that the first cylinder is inserted into the receiving groove. Then, press the manual switch 8 on the first upright plate 61 to start the hydraulic cylinder 9. The moving part of the hydraulic cylinder 9 drives the second upright plate 71 to move to the left, so that the crossbar 72 applies a force to the left to the second cylinder 62, pressing against the second cylinder 62, so that the winding of the exciter motor is completely inserted into the circular groove. Then the servo motor 4 starts, driving the circular plate of the bending die 5 to rotate, thereby applying the bending force of the winding. Since the winding is fixed by the receiving groove in the sliding device 5, when the first cylinder rotates, it will cause the winding to bend at a preset angle. The clearance groove ensures that it will not interfere with other parts of the winding during the bending process. After the bending is completed, the servo motor 4 stops working, the hydraulic cylinder 9 retracts, and the operator pushes the sliding device 6 to the right along the direction of the guide column group 3 to take out the exciter motor whose winding has been bent.
