Description

Technical Field

[0001] This utility model relates to the field of flat wire motor stator processing technology, and in particular to a flat wire motor stator clamping device. Background Technology

[0002] The stator of a flat wire motor is usually composed of an iron core and an excitation winding. The iron core has a through hole in the center. To ensure electrical insulation between the excitation winding and the stator iron core, an insulation layer must be installed at the slot of the iron core. Among these methods, using insulating paper for paper insertion is the simplest and most efficient insulation method.

[0003] When inserting the insulating paper, the stator must first be fixed in place. Then, the formed insulating paper is inserted one by one into the slot of the stator, ensuring that each piece of insulating paper fits tightly against the slot wall. The existing stator clamp is not stable enough. During the paper insertion process, the stator is prone to displacement, causing the edge of the insulating paper to rub against the slot wall, resulting in wrinkles or tears, which affects the insulation effect.

[0004] Therefore, existing technologies still need improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a flat wire motor stator clamping device, which aims to solve the problem that the existing flat wire motor stator has insufficient stability during paper insertion, resulting in the friction between the edge of the insulating paper and the groove wall, causing wrinkles or tears, which affects the insulation effect.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] During the processing of the flat wire motor stator, the formed insulating paper needs to be inserted into the slots on the stator. When inserting the paper, the stator needs to be moved to a predetermined position to align the slots with the insulating paper, ensuring accurate insertion. After moving to the predetermined position, the stator needs to be rotated circumferentially to ensure all slots are filled with insulating paper. During this process, the stator may slightly wobble or tilt due to uneven weight distribution or external forces during installation, causing misalignment between the motor and the mounting base. This misalignment can lead to friction between the insulating paper edges and the slot walls, resulting in wrinkles or tears and affecting the insulation performance.

[0035] Based on this, embodiments of this application disclose a stator clamping device for a flat wire motor, such as... Figure 1 As shown, it includes: a fixed base and at least two limiting blocks; the fixed base is provided with at least two slots 110; the at least two slots 110 are spaced apart on the fixed base 100; the fixed base 100 is used to place the flat wire motor stator 300 and constrain the flat wire motor stator 300 to move along a first direction; at least two limiting blocks 200 are disposed at the center position of the slots 110; the at least two limiting blocks 200 constrain the flat wire motor stator 300 to move along a second direction.

[0036] In use, the fixing base 100 has at least two slots 110, and a limiting block 200 is provided at the center of each slot 110. The fixing base 100 and the limiting block 200 cooperate with each other to limit the flat wire motor stator 300 in the first direction and the second direction respectively, so as to prevent the flat wire motor stator 300 from shifting during the production and processing process and affecting the processing accuracy.

[0037] Specifically, the fixed base 100 has at least two slots 110 spaced apart, and each slot 110 has a limiting block 200 at its center. After the flat wire motor stator 300 is placed on the fixed base 100, when the fixed base 100 is moved or rotated, the flat wire motor stator 300 will have a small axial or radial displacement. At this time, the fixed base 100 and the limiting block 200 cooperate with each other to block the flat wire motor stator 300 from shifting in different directions and correct the positional error of the flat wire motor stator 300, ensuring the concentricity of the flat wire motor stator 300 and the center of the fixed base 100. This ensures that when the fixed base 100 is moved or rotated, the flat wire motor stator 300 moves or rotates by the same distance or angle, ensuring that the stator slot 110 is aligned with the insulating paper and improving the paper insertion accuracy.

[0038] In this embodiment, as Figure 1 and Figure 2As shown, the fixing base 100 is recessed inward to form a groove 120. The fixing base 100 has two slots 110 in the second direction Y, and a limiting block 200 is provided at the center of each of the two slots 110. The first direction X and the second direction Y are perpendicular to each other.

[0039] Specifically, when the flat wire motor stator 300 is placed in the groove 120 and the fixed base 100 is moved, the outer wall of the flat wire motor stator 300 fits against the inner wall of the groove 120, thereby restricting the displacement of the flat wire motor stator 300 in the first direction X. To further reinforce the flat wire motor stator 300, a limiting block 200 is provided at the center of the slot 110 in the second direction Y to block the flat wire motor stator 300 in the second direction Y. Thus, the flat wire motor stator 300 is fixed in both the first direction X and the second direction Y, preventing slight displacement of the flat wire motor stator 300 in the axial and radial directions, effectively strengthening the stability of the flat wire motor stator 300 during paper insertion, and improving the paper insertion accuracy.

[0040] In one implementation, such as Figure 2 As shown, the mounting base 100 has multiple slots 110 spaced apart, and each slot 110 is provided with a limiting block 200 to restrict the displacement of the flat wire motor stator 300 in different positions. In this embodiment, the limiting block 200 and the groove 120 of the mounting base 100 together form a stable constraint system for the flat wire motor stator 300, so that the flat wire motor stator 300 can remain stable in the mounting base 100 and will not easily shift its position, thereby effectively restricting the movement of the flat wire motor stator 300 in the mounting base 100.

[0041] In another embodiment of this utility model, an annular protrusion 121 is provided in the groove 120; the annular protrusion 121 abuts against the bottom of the flat wire motor stator 300. Specifically, the annular protrusion 121 is provided at the bottom of the groove 120. When the flat wire motor stator 300 is placed on the fixing base 100, the annular protrusion 121 abuts against the bottom of the stator, thereby suspending the stator and creating a certain space between the bottom of the stator and the bottom of the fixing base 100. This design allows the formed insulating paper to be smoothly inserted from the top slot 110 of the stator and extended from the bottom slot 110, avoiding damage to the insulating paper extending from the bottom slot 110.

[0042] In one implementation, such as Figure 2As shown, the limiting block 200 is arranged in a stepped protrusion. Similarly, the limiting block 200 is set in a stepped shape, and in specific implementation, the limiting block 200 has a protrusion. When the limiting block 200 constrains the flat wire electronic stator in one direction, the protrusion also supports the bottom of the flat wire motor stator 300, further improving the stability of the flat wire motor stator 300. In this embodiment, the vertical distance from the protrusion to the bottom of the fixing seat 100 is equal to the height of the annular protrusion 121, ensuring that the flat wire motor stator 300 is horizontal.

[0043] In another embodiment of this utility model, such as Figure 2 and 3 As shown, the fixing base 100 further includes: a first positioning groove 130, disposed on the inner side wall of the groove 120; a positioning post 140, embedded in the positioning groove; the positioning post 140 at least partially protrudes out of the first positioning groove; a second positioning groove 310 is provided on the flat wire stator motor corresponding to the position of the positioning post 140; the positioning post 140, which at least partially protrudes out of the first positioning groove 130, engages with the second positioning groove 310.

[0044] like Figure 3 As shown, specifically, the positioning post 140 is fixedly disposed in the first positioning groove 130, and at least partially extends out of the first positioning groove 130. When placing the flat wire motor stator 300, the portion of the positioning post 140 extending out of the first positioning groove 130 on the flat wire motor stator 300 is engaged with the second positioning groove 310. At this time, a portion of the positioning post 140 is engaged with the first positioning groove 130, and another portion is engaged with the second positioning groove 310. This design provides a reference positioning for the flat wire motor stator 300. That is, during installation, the positioning post 140 and the first and second limiting grooves are used as positioning points to ensure the initial positional accuracy between the fixed base 100 and the flat wire motor stator 300, and to ensure concentricity in subsequent processing.

[0045] In this embodiment, multiple first positioning slots 130 are provided; multiple first positioning slots 130 are spaced apart circumferentially along the fixed base 100; multiple positioning posts 140 are provided, and multiple positioning posts 140 are spaced apart circumferentially along the fixed base 100. At the same time, multiple second positioning slots 310 are also provided accordingly. Similarly, a portion of the multiple positioning posts 140 is in the first positioning slot 130, and another portion is in the second positioning slot 310, so as to ensure the concentricity of the flat wire motor stator 300 and the fixed base 100 during initial installation through multiple positioning points.

[0046] In another embodiment of this utility model, such as Figure 1As shown, the flat wire motor stator clamping device further includes: a base 400, with a connecting hole (not shown in the figure) at its center; the connecting hole is concentrically arranged with the fixed seat 100; the fixed seat 100 is rotatably mounted on the base 400; a first motor 500, the drive shaft of the first motor 500 passing through the connecting hole and being connected to the base 400 for transmission; the first motor 500 is used to drive the fixed seat 100 to rotate. When the flat wire motor stator 300 is fixed on the fixed seat 100, the rotation of the flat wire motor stator 300 is achieved by rotating the fixed seat 100. By rotating the flat wire motor stator 300, the stator slots 110 are filled with shaped insulating paper. Specifically, the first motor 500 includes, but is not limited to, a drive cylinder or a drive motor; more specifically, the first motor 500 can drive the fixed seat 100 to rotate by a motor drive, a hydraulic drive, or a pneumatic drive.

[0047] In this embodiment, the flat wire motor stator clamping device further includes a flange reducer 600; one end of the flange reducer 600 is connected to the first motor 500 for transmission, and the other end is connected to the fixed base 100. The flange reducer 600 reduces the output speed of the first motor 500, achieving more precise speed control of the fixed base 100. Simultaneously, the first motor 500 drives the fixed base 100 to rotate via the flange reducer 600. The reduction effect of the reducer allows minute angular changes in the motor to be more accurately converted into angular changes in the fixed base 100, facilitating high-precision positioning. This ensures that each time the fixed base 100 rotates, the slot 110 of the flat wire motor stator 300 can accurately rotate to the predetermined position and align with the insulating paper.

[0048] In this embodiment, the base 400 is further provided with a sliding groove; the sliding groove is disposed on both sides of the base 400; the flat wire motor stator clamping device further includes: a slide rail 700, on which the sliding groove is slidably disposed; a second motor (not shown in the figure), which is drively connected to the base 400; the second motor is used to drive the base 400 to slide. The second motor includes, but is not limited to, a drive cylinder or a drive motor. More specifically, the second motor can move the base 400 along the first direction X via a motor drive, a hydraulic drive, or a pneumatic drive, thereby moving the flat wire motor stator 300.

[0049] In another embodiment of this utility model, the flat wire motor stator clamping device further includes a reinforcing block 800; the reinforcing block 800 is connected to the base 400. Specifically, in actual use, the flat wire motor stator 300 clamping device is used in conjunction with a work box and a worktable. When the base 400 is moved to a predetermined position along the first direction X, the reinforcing block 800 fixes the base 400 to the worktable. During the subsequent rotation of the fixing seat 100, the base 400 is prevented from shifting, ensuring that the fixing seat 100 rotates in the predetermined position so that the insulating paper is aligned with the stator slot 110, improving the paper insertion accuracy.

[0050] In summary, this utility model discloses a flat wire motor stator clamping device, comprising: a fixed base and at least two limiting blocks; the fixed base has at least two slots; the at least two slots are spaced apart on the fixed base; the fixed base is used to place the flat wire motor stator and constrain the flat wire motor stator to move along a first direction; the at least two limiting blocks are disposed at the center position of the slots; the at least two limiting blocks constrain the flat wire motor stator to move along a second direction. This application, through the cooperation of the fixed base and the limiting blocks, limits the flat wire motor stator in at least two directions; when the fixed base rotates, the limiting blocks abut against the flat wire motor stator, effectively preventing its displacement, allowing the insulating paper to be accurately inserted into the flat wire motor stator, solving the problem of insufficient stability of the existing flat wire motor stator during paper insertion, causing the edge of the insulating paper to rub against the slot wall, resulting in wrinkles or tears, affecting the insulation effect.
