Description

Technical Field

[0001] The present invention relates to the technical field of flat wire motor assembly equipment, and in particular to a folding-wing manual wire insertion mechanism. Background Art

[0002] A flat wire motor typically consists of a stator, rotor, and reducer. The stator is one of the motor's core components. The stator is the stationary part of the motor, typically made of coils wound with copper wire and mounted stationary within the motor housing. Its primary function is to generate a magnetic field, driving the rotor and thus completing the motor's operation.

[0003] The primary function of a flat wire motor's stator is to generate a magnetic field, which can be either a constant DC field or a variable AC field. When the current flowing through the stator coil changes, the magnetic flux in the conductor changes. This flux change affects the shape of the magnetic field, which in turn determines the direction and speed of the rotor's rotation. The magnetic field generated in the stator interacts with the magnetic field in the rotor, causing the rotor to rotate due to the torque.

[0004] During the production and processing of flat-wire motor stators, bent copper wire must be manually inserted into the stator core. However, this method is cumbersome, time-consuming, and labor-intensive. Furthermore, manual insertion can result in uneven ends of the corolla, loss of copper wire straightness, and significant misalignment between individual Upin pins. This poor stability significantly impacts subsequent stator assembly work.

[0005] In order to solve the above problems, the present invention proposes a folding-wing manual wire insertion mechanism, which is used to assist manual wire insertion and has simple operation and high wire insertion accuracy. Summary of the Invention

For example, A and / or B can represent the following three situations: A exists alone, A and B exists simultaneously, and B exists alone.

[0061] The embodiments of the present invention will be described in more detail below through examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0062] In a specific embodiment, Figure 1-Figure 3 As shown, a folding-wing manual wire insertion mechanism includes several card positioning forks 1, an iron core positioning block 2, a pad adjustment block 3, a fork opening and closing rotary handle 4, a tooling block 5, a slot number marking disk 6 and a body 7.

[0063] In this embodiment, the height adjustment block 3 is used to adjust the depth of the flat wire inserted into the iron core when the wire is inserted manually.

[0064] The core positioning block 2 is fixed to the lower surface of the height adjustment block 3. The outer diameter of the core positioning block 2 is the same as the inner diameter of the stator core 100. The core positioning block 2 is used to be embedded in the interior of the stator core 100 to facilitate the wire insertion operation.

[0065] The tooling block 5 is provided on the outer surface of the height adjustment block 3. When in use, the tooling block 5 is stuck between the wire insertion slots on the upper surface of the stator core 100. Its function is to prevent the core positioning block 2 from being inserted too deeply and affecting the insertion of the wires.

[0066] The slot number marking plate 6 is sleeved on the body 7; the slot number marking plate 6 is provided with slot number markings corresponding to the insertion slots of the stator core 100. This design is to prevent manual insertion into the wrong slot and achieve circumferential positioning through the slot number markings.

[0067] The fork is opened and closed by rotating the handle 4, which includes a grip portion and a threaded rod;

[0068] The grip portion is fixed to the upper end of the threaded rod, which is screwed into the body 7;

[0069] A torque transmission mechanism is provided in the body 7;

[0070] The torque transmission mechanism is used to transmit torque to a plurality of card-issuing positioning forks 1 .

[0071] In this embodiment, the grip portion of the fork opening and closing handle 4 is used by the operator to grasp and perform pick-up, placement, or insertion operations. The threaded rod is used to transmit the operator's torque to the torque transmission mechanism, which transmits the force to the card issuing and positioning fork 1. The card issuing and positioning fork 1 is opened or retracted according to the direction of the torque.

[0072] One end of a plurality of card issuing positioning forks 1 is fixed to the body 7; the card issuing positioning forks 1 are distributed along the circumferential direction of the body 7; the card issuing positioning forks 1 are located below the slot number marking disk 6, and the angular spacing between two adjacent card issuing positioning forks 1 is consistent with the angular spacing between two adjacent slot number markings.

[0073] In this embodiment, each card-issuing positioning fork 1 corresponds to a group of wire insertion slots of the stator core 100 .

[0074] In this embodiment, the torque transmission mechanism includes a connecting rod 7-1, a connecting plate 7-2, a fork connecting rod 7-3, and a ball plunger 7-4;

[0075] The upper end of the connecting rod 7-1 is connected to the lower end of the threaded rod 4-2, and the ball plunger 7-4 is arranged on the side of the lower end of the connecting rod 7-1. One end of the connecting plate 7-2 is connected to the connecting rod 7-1, and the other end is connected to the fork connecting rod 7-3. The fork connecting rod 7-3 is connected to the hairpin positioning fork 1.

[0076] In this embodiment, the function of the ball plunger 7-4 is to clamp the connecting rod 7-1 when the ball head is fully opened, thereby preventing the card issuing positioning fork 1 from retreating. In this way, it can be ensured that the ball plunger 7-4 can only be disengaged by applying force by rotating the threaded rod 4-2 in the reverse direction, thereby retracting the card issuing positioning fork 1.

[0077] In this embodiment, one end of the fork link 7-3 is fixed to the card positioning fork 1 through the first rotating pin 7-5, and the other end is fixed to the connecting plate 7-2 through the second rotating pin 7-6. A rotating pin pressure plate 7-7 is also provided between the fork link 7-3 and the connecting plate 7-2.

[0078] In this embodiment, the function of the rotating pin pressing plate 7-7 is to fix the second rotating pin 7-6 to prevent the second rotating pin 7-6 from tilting up and falling off due to excessive rotation angle.

[0079] In this embodiment, the materials of the card positioning fork 1, the iron core positioning block 2, the height adjustment block 3, the fork opening and closing rotary handle 4, the tooling stop block 5 and the slot number marking disk 6 are 45 steel, SUS304 stainless steel, POM, 45 steel, POM and POM respectively.

[0080] The specific operation process of this embodiment is as follows:

[0081] Tooling assembly:

[0082] like Figure 4 As shown, the folding-wing manual wire insertion mechanism is placed on the stator core 100 , the core positioning block 2 is inserted into the inner diameter of the stator core 100 , and the tooling stopper 5 is clamped on the upper surface of the stator core 100 .

[0083] Before inserting the wire, check whether the slot mark on the slot number marking disk 6 corresponds to the wire insertion slot of the stator core 100 one by one. If not, rotate the folding-wing manual wire insertion mechanism until the slot mark corresponds to the wire insertion slot one by one.

[0084] Plug in the cable:

[0085] like Figure 5 As shown, the copper wires to be plugged in are manually placed on the card positioning fork 1 according to the notch marks until all the copper wires are placed.

[0086] Twisting the shift fork opens and closes the gripping portion 4-1 on the rotary handle 4, and the threaded rod 4-2 transmits the torque to the shift fork link 7-3 through the connecting top rod and the connecting plate. The shift fork link 7-3 drives the second rotating pin 7-6 and the first rotating pin 7-5 to rotate, thereby driving the hairpin positioning shift fork 1 to retract, and all the copper wires fall into the wire slot in the stator core 100.

[0087] Tooling retraction:

[0088] Hold the shift fork to open and close the gripping part of the rotating handle 4, and remove the folding wing manual wire insertion mechanism from the stator core 100 after the wire insertion is completed. Figure 6 shown.

[0089] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
