Description

Technical Field

[0001] This utility model relates to the field of insulating paper flaring technology, specifically a paper flaring machine for processing flat wire motors. Background Technology

[0002] During stator manufacturing, insulating paper is first inserted into the stator slots, and then copper wires are inserted into the insulating paper, where they are wrapped by the insulating paper. This ensures that the copper wires in each slot are insulated from the stator core, guaranteeing the good performance of the motor stator. To facilitate the insertion of the copper wires into the insulating paper, the ends of the insulating paper need to be widened.

[0003] Application number CN202422697933.2 discloses a device with self-heating that can achieve one-time flaring of insulating paper, including a base plate and a hydraulic cylinder. A placement frame is fixedly connected to the top of the base plate, and a rotor is arranged inside the placement frame. Insulating paper is arranged on the inner walls of multiple grooves on the inner side of the rotor. A flaring assembly is arranged at the output end of the hydraulic cylinder. The flaring assembly includes a push plate fixedly connected to the output end of the hydraulic cylinder. Multiple flaring rods adapted to the grooves are fixedly connected to the bottom of the push plate. The bottom edge of the flaring rod is set with an arc surface, and a heating rod is arranged at the bottom end of the flaring rod.

[0004] While the aforementioned existing technology can enlarge the insulating paper, the enlarging rod is difficult to insert accurately into the insulating paper. When there is a slight deviation between the enlarging rod and the insulating paper, the enlarging rod will squeeze the insulating paper, which may cause damage to the insulating paper.

[0005] The purpose of this utility model is to provide a paper spreading machine for processing flat wire motors, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A paper spreading machine for processing flat wire motors includes a worktable, a slider, a stator clamping part, a paper spreading assembly, a stator, insulating paper, and an auxiliary alignment assembly. The slider is movably mounted on a guide rail on the worktable. The paper spreading assembly is disposed on the worktable and located above the slider. The stator is disposed on the stator clamping part, and insulating paper is arranged in a circumferential array on the stator. The stator clamping part is rotatably mounted on the slider, and the auxiliary alignment component is located between the paper spreading component and the stator clamping part to drive the stator clamping part to rotate so that the paper spreading end of the paper spreading component is facing the insulating paper.

[0007] Preferably, the paper spreading assembly includes a lifting plate, an electric cylinder, a cylindrical mounting frame, and a spreading rod as the spreading end. The lifting plate is vertically and movably mounted on the worktable. The electric cylinder is located on the worktable and cooperates with the lifting plate to drive the lifting plate to move. The cylindrical mounting frame is mounted on the lifting plate, and the cylindrical mounting frame is circumferentially arrayed with the same number of spreading rods as the insulating paper.

[0008] Preferably, the auxiliary alignment assembly includes a gear ring, a gear, a stepper motor, mounting holes, and a centering rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a paper spreading machine for processing flat wire motors. During operation, an auxiliary alignment component allows the spreading rod and the insulating paper to be aligned before the spreading rod contacts the insulating paper.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4 This utility model provides a technical solution: A paper-expanding machine for processing flat wire motors includes a worktable 1, a slider 2, a stator clamping part 3, a paper-expanding assembly 4, a stator 5, insulating paper 6, and an auxiliary alignment assembly 7. The slider 2 is movably mounted on a guide rail on the worktable 1, and the slider 2 moves linearly along the guide rail on the worktable 1. The paper-expanding assembly 4 is located on the worktable 1 and above the slider 2. The stator 5 is located on the stator clamping part 3, which is used to clamp the stator 5. The stator 5 is circumferentially arrayed with insulating paper 6. During the production of the flat wire motor, the coil needs to be embedded in the slot of the iron core in the stator 5. To prevent the coil from directly contacting the iron core and causing a short circuit, insulating paper 6 must be inserted between the coil and the iron core slot wall, wherein: The stator clamping part 3 is rotatably mounted on the slider 2. An auxiliary alignment component 7 is positioned between the paper spreading assembly 4 and the stator clamping part 3 to rotate the stator clamping part 3, ensuring that the spreading end of the paper spreading assembly 4 is directly facing the insulating paper 6. This ensures that the spreading end of the paper spreading assembly 4 is inserted into the insulating paper 6, facilitating the spreading operation of the paper spreading end of the paper spreading assembly 4 on the insulating paper 6. This prevents misalignment between the spreading end of the paper spreading assembly 4 and the insulating paper 6, which could lead to compression and folding of the insulating paper 6, uneven spreading, poor spreading effect, and difficulty in preventing direct contact between the coil and the iron core.

[0016] As a preferred embodiment, the stator clamping part 3 is used to clamp the stator 5 in the production process of flat wire motor. It is a general equipment in the production process of flat wire motor, and its principle and solution will not be described in detail here.

[0017] In a preferred embodiment, the paper spreading assembly 4 includes a lifting plate 41, an electric cylinder 42, a cylindrical mounting frame 43, and flaring rods 44 serving as the spreading end. The lifting plate 41 is vertically and movably mounted on the worktable 1, forming a vertically movable joint on the worktable 1. The electric cylinder 42 is located on the worktable 1 and cooperates with the lifting plate 41 to drive the lifting plate 41. The cylindrical mounting frame 43 is located on the lifting plate 41, and the cylindrical mounting frame 43 has flaring rods 44 arranged in a circumferential array, the same number as the number of insulating paper 6. Figure 4 As shown, the flaring rod 44 is the flaring end of the paper flaring assembly 4. When the flaring rod 44 is inserted into the insulating paper 6, the side of the flaring rod 44 will squeeze the side of the insulating paper 6, thereby achieving the purpose of flaring.

[0018] As a preferred embodiment, the insulating paper 6 is flared using the flaring rod 44, which is a conventional technique for those skilled in the art, and its principle and solution will not be elaborated here.

[0019] In a preferred embodiment, the auxiliary alignment assembly 7 includes a gear ring 71, a gear 72, a stepper motor 73, mounting holes 74, and a centering rod 75. The gear ring 71 is fixedly sleeved on the outside of the stator clamping part 3. The gear 72 is rotatably mounted on the slider 2 and meshes with the gear ring 71. The stepper motor 73 is mounted on the slider 2 and is poweredly connected to the gear 72. The stepper motor 73 is self-locking. The stator 5 has four mounting holes 74 arranged in a circumferential array. The cylindrical mounting bracket 43 is provided with a centering rod 75, which faces the mounting holes 74. When it is necessary to align the flared rod 44 and the insulating paper 6, the electric cylinder 42 simply drives the centering rod 75 on the lifting plate 41 to contact the stator 5. Then, the gear ring 71 is rotated by the gear 72, which in turn drives the stator 5 on the stator clamping part 3 to rotate synchronously. This allows the centering rod 75 to be inserted concentrically into the mounting hole 74, thus achieving the purpose of aligning the flared rod 44 and the insulating paper 6.

[0020] In a preferred embodiment, the auxiliary alignment assembly 7 further includes ball bearings 76, which are rotatably mounted on the end of the centering rod 75. The ball bearings 76 prevent damage to the stator 5.

[0021] In a preferred embodiment, to further prevent the ball bearing 76 from damaging the stator 5, the ball bearing 76 is connected to the centering rod 75 via a damping rod. The damping rod is connected to the fixed end by a spring at the damping end. The damping rod is a conventional technical means, and its principle and solution will not be described in detail here. In this way, the ball bearing 76 can extend and retract on the centering rod 75 with the damping end of the damping rod, thereby preventing the ball bearing 76 from squeezing the stator 5 when the electric cylinder 42 drives the lifting plate 41 to descend.

[0022] In a preferred embodiment, the end of the centering rod 75 near the stator clamping part 3 is longer than the end of the flared rod 44 near the stator clamping part 3. This arrangement ensures that when the flared rod 44 and the insulating paper 6 are aligned, the flared rod 44 will not contact the insulating paper 6, thereby preventing the flared rod 44 from colliding with the insulating paper 6 when the stator 5 rotates, thus avoiding damage to the insulating paper 6.

[0023] The working principle of this utility model: When using this device, first place the stator 5 onto the slider 2 via the stator clamping part 3, then position the stator 5 directly below the paper spreading assembly 4. At this time, start the electric cylinder 42 to drive the lifting plate 41 to move downward, thereby causing the ball bearing 76 on the centering rod 75 to contact the stator 5. Then, drive the gear ring 71 to rotate via the gear 72, thereby causing the stator 5 on the stator clamping part 3 to rotate synchronously, so that the centering rod 75 can be directly inserted into the mounting hole 74. At this time, the purpose of aligning the flaring rod 44 and the insulating paper 6 is achieved.

[0024] After alignment, the electric cylinder 42 continues to drive the lifting plate 41 downwards, causing the centering rod 75 to insert into the insulating paper 6, thereby achieving the purpose of widening the insulating paper 6. Then, the electric cylinder 42 is activated to drive the lifting plate 41 to reset.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
