Description

Technical Field

[0001] The utility model relates to the technical field of magnetic levitation trains, in particular to an insulating paper covering tool for a stator core. Background Art

[0002] Maglev trains rely on magnetic force to suspend the vehicle above the track. The attraction between the levitation electromagnet and the stator core of the linear motor on the track lifts the train upward and suspends it above the track. The linear motor on the track then propels the train forward, reaching speeds exceeding 600 km / h. Maglev trains structurally cling to the track beams, preventing derailment and ensuring high safety and reliability. Furthermore, maglev rail eliminates the noise and vibration associated with conventional wheel-rail contact, making it environmentally friendly and bridging the travel speed gap between aviation and high-speed rail passenger transport.

[0003] The stator of a linear motor consists of a stator core and stator windings. The stator core is typically a silicon steel core, and the stator windings are typically aluminum foil windings. During linear motor assembly, a layer of insulating paper must be wrapped around the outer circumference of the silicon steel core to separate the silicon steel core and the aluminum foil windings. However, due to current technological limitations, the silicon steel core must be flipped during the insulating paper winding process. Furthermore, the silicon steel core is heavy, weighing up to 5-10 kg, and the winding of the insulating paper must be done manually, which is labor-intensive and results in relatively low assembly efficiency.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] The present invention discloses an insulating paper covering tool for a stator core, as shown in the attached figure. Figures 1 to 3 As shown, the stator assembly comprises a fixed base 1, a rotating support 2, and several sets of fixing fixtures 3. The fixed base 1 is fixedly mounted, specifically, secured to a work surface with bolts. The rotating support 2 is rotatably mounted on the fixed base 1 to support the stator core. All fixing fixtures 3 are positioned along the outer edge of the rotating support 2.

[0042] When wrapping the insulating paper, first fix the stator core on the rotating support 2, and then rotate the rotating support 2 so that the stator core rotates synchronously with the rotating support 2; when the rotating support 2 drives the stator core to rotate to a preset angle, the stator core rotates into place, and the insulating paper is laid on the target side of the stator core. The fixing clamp 3 clamps the insulating paper on the target side of the stator core; the rotating support 2 drives the stator core for one circle to complete the wrapping of the insulating paper. The whole operation process is relatively simple, there is no need to frequently rotate the stator core manually, the labor intensity is reduced, and the assembly efficiency is high.

[0043] It should also be noted that the preset angle in this article refers to the optimal angle at which the rotating support 2 rotates when the stator core rotates from the previous insulating paper application position to the next position to be applied. This ensures that the position to be applied always faces the operating station, facilitating the application of the insulating paper. The target side in this article refers to the side of the stator core to which the insulating paper is to be applied.

[0044] The stator core insulation paper coating tooling also includes a clamping spacer, which is provided between the pressing head 31 of the fixing fixture 3 and the insulation paper. The clamping spacer is used to separate the pressing head 31 and the insulation paper, so that the pressing head 31 can press and fix the insulation paper to the stator core through the clamping spacer, avoiding direct contact between the pressing head 31 and the insulation paper, which may cause scratches on the insulation paper. Of course, to further enhance the anti-scratch effect, the clamping spacer is preferably a flexible spacer, and the pressing head 31 is also preferably a flexible pressure head, such as a silicone spacer or a rubber pressure head. The use of flexible materials can also achieve an anti-scratch effect.

[0045] In a preferred embodiment, the clamping plate is fixedly connected to the pressing head 31. The pressing head 31 directly drives the clamping plate to press against the side of the stator core, eliminating the need for manual installation of the clamping plate and preventing the insulation paper from being misaligned due to the installation of the clamping plate, thereby improving assembly efficiency and quality. Of course, the clamping plate and the pressing head 31 are also separated. Before the fixing fixture 3 presses the insulation paper, the clamping plate can be pressed against the insulation paper separately to achieve a scratch-proof effect.

[0046] As a preferred embodiment, the rotating support 2 is provided with a limiting protrusion, which cooperates with the structural groove of the stator core to limit the position of the stator core on the rotating support 2, ensuring that the stator core is installed on the rotating support 2 quickly and accurately, thereby improving assembly efficiency.

[0047] The rotating support 2 is provided with several fixing holes 21. The positioning core is fixed in these fixing holes 21 by means of fastening bolts. This allows the stator core to be securely fixed to the rotating support 2, preventing the stator core from shaking during the insulating paper coating process, which could affect product quality. To compensate for machining errors between the stator core and the rotating support 2, the fixing holes 21 are waist-shaped holes. By adjusting the position of the fastening bolts within the waist-shaped holes, the relative position of the stator core and the rotating support 2 can be adjusted. Of course, the fixing holes 21 can also be threaded holes, which are not specifically limited here.

[0048] The insulating paper wrapping tooling for the stator core also includes a rotating handle 4, a rotating shaft, and a bevel gear set. The rotating handle 4 is rotatably mounted on an extension portion of the fixed base 1, and the rotating shaft is rotatably inserted into the extension portion, with the rotating handle 4 being perpendicular to the rotating shaft. The rotating shaft is fixedly connected to the rotating support 2, so that the rotating shaft drives the rotating support 2 to rotate. The bevel gear set is located between the rotating handle 4 and the rotating shaft and includes a driving bevel gear and a driven bevel gear that mesh with each other. The driving bevel gear is fixedly connected to the rotating handle 4, and the driven bevel gear is fixedly connected to the rotating shaft to transmit the torque of the rotating handle 4 to the rotating shaft. In this way, the position of the positioning core installed on the rotating support 2 can be precisely adjusted by manually rotating the rotating handle 4.

[0049] Each set of fixing clamps 3 includes a support seat 32, a lifting and pressing rod 33, a pushing rod 34 and a connecting rod 35. The support seat 32 is fixed to the back of the rotating support 2. The top of the support seat 32 is formed with an inclined surface. The two ends of the inclined surface are respectively formed with a protrusion and a hinge portion. The protrusion is set higher than the hinge portion. The lifting and pressing rod 33 is hingedly connected to the hinge portion. One end of the pushing rod 34 is hingedly connected to the protrusion and the other end is fixed with a pressing head 31. One end of the connecting rod 35 is hingedly connected to the lifting and pressing rod 33 and the other end is hingedly connected to the middle section of the pushing rod 34. When the lifting and pressing rod 33 is lifted to the first position, the lifting and pressing rod 33 lifts the pushing rod 34 through the connecting rod 35, and the pressing head 31 is moved away from the stator core. When the lifting and pressing rod 33 is pressed down to the second position, the lifting and pressing rod 33 pushes the pushing rod 34 down through the connecting rod 35, and the pressing head 31 is pressed against the stator core to achieve compression of the insulating paper. The structure of each set of fixing fixtures 3 is relatively simple and easy to operate. Of course, the structure of the fixing fixtures 3 is not limited thereto.

[0050] Of course, the rotation of the rotating support 2 is not limited to the handle. For example, the insulating paper covering tooling of the stator core also includes a rotating drive member, an angle detection member and a controller. The rotating drive member is fixedly connected to the rotating support 2, and can specifically be a servo motor. The angle detection member is used to detect whether the rotating support 2 rotates a preset angle, and can specifically be an angle sensor. The controller is connected to the rotating drive member and the angle detection member, respectively. When the angle detection member detects that the rotating support 2 rotates a preset angle, the angle detection member sends a signal to the controller, and the controller interprets and processes the signal and sends it to the rotating drive member to control the rotating drive member to automatically stop, thereby automatically adjusting the position of the stator core, with a high degree of automation and high adjustment accuracy.

[0051] It should be noted that the controller should include a signal receiving part, a signal judging part and a signal sending part. The signal receiving part is used to receive the electrical signal sent by the detection part such as the angle detection part. The signal judging part and the signal receiving part are electrically connected so that the signal judging part is used to judge whether the signal received by the signal receiving part is a trigger signal. The signal sending part and the signal judging part are electrically connected so that the signal sending part sends the judgment signal generated by the signal judging part to the execution part such as the rotating drive part. The specific setting method of the signal receiving part, the signal judging part and the signal sending part can refer to the existing technology; in the present utility model, only the application scenarios of the above three are changed, and no substantial improvement is made thereto. Obviously, the controller with this structure is widely used in existing automatic control equipment, such as MCU, DSP or single-chip microcomputer. The key point of the present utility model is that the controller combines the rotating drive part and the angle detection part.

[0052] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0053] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
