Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to an assembly fixture for stator coils. Background Technology

[0002] The stator coil is a conductive coil wound on the stator core of the motor. In an AC motor, the stator coil is directly connected to the three-phase power supply and generates a rotating magnetic field through the current.

[0003] Existing stator coils are usually installed in the thrust ring of the motor by embedding. The thrust ring has a groove that matches the stator coil. The diameter of the groove is smaller than the diameter of the stator coil, so that the stator coil undergoes a certain deformation during the embedding process of the thrust ring, thereby fixing the stator coil in the thrust ring.

[0004] However, the existing embedded method can damage the enameled wire of the stator coil, which is not conducive to the normal use of the stator coil. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an assembly fixture for stator coils to solve the technical problem in the prior art where the existing operation method of installing stator coils on thrust rings leads to damage to the enameled wire of the stator coils.

[0006] The present invention provides an assembly fixture for a stator coil, including a thrust ring having a first receiving groove and a plurality of fixing posts arranged at intervals along the circumference of the thrust ring.

[0007] Each of the aforementioned fixing posts is screwed to the thrust ring, and a portion of each fixing post is located within the receiving groove.

[0008] Wherein, the diameter of the first receiving groove is larger than the diameter of the stator coil, and when the stator coil is assembled in the first receiving groove, a gap is formed between the stator coil and the end of the fixing column, allowing the fixing column to move toward the stator coil.

[0009] Furthermore, the assembly fixture also includes a positioning block, a fixing block, and multiple connecting parts;

[0010] The positioning block and the fixing block are used to be disposed on opposite sides of the stator coil, and the plurality of the connecting pieces are used to pass through the through holes of the stator coil to connect the positioning block and the fixing block;

[0011] The thrust ring is further provided with a second receiving groove that communicates with the first receiving groove. The second receiving groove is used to engage a portion of the positioning block.

[0012] Furthermore, the depth of the second receiving groove is smaller than the height of the positioning block, such that when the positioning block is engaged in the second receiving groove, a portion of the positioning block is located within the first receiving groove.

[0013] Furthermore, the diameter of the second receiving tank is smaller than the diameter of the first receiving tank.

[0014] Furthermore, each of the plurality of fixed posts includes a fixing part and a threaded part that is screwed to the thrust ring;

[0015] One end of the threaded portion is located inside the first receiving groove and connected to the fixing portion, while the other end of the threaded portion is located outside the first receiving groove.

[0016] Furthermore, the thrust ring is provided with multiple sliding grooves, and each of the fixed parts is slidably connected to the corresponding sliding groove.

[0017] Furthermore, multiple grooves are circumferentially spaced within the thrust ring, with the center of the thrust ring as the origin.

[0018] Furthermore, the fixing part is also provided with a hole for accommodating one end of the threaded part.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the stator coil assembly fixture of this utility model, by setting the diameter of the first receiving groove to be larger than the diameter of the stator coil, the stator coil can be assembled without damage, avoiding damage to the enameled wire of the stator coil. When it is necessary to fix the stator coil in the thrust ring, the multiple fixing posts are screwed to the thrust ring, allowing the operator to rotate the fixing posts so that one end of the fixing posts moves toward the stator coil, thereby fixing the stator coil in the thrust ring. At the same time, since the multiple fixing posts in this embodiment are arranged circumferentially and at intervals along the thrust ring, the multiple fixing posts can fix the stator coil from multiple positions, further ensuring the stability of the stator coil fixed in the thrust ring.

Detailed Implementation

[0026] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figures 1 to 4 The image shows an assembly fixture for a stator coil according to one embodiment of the present invention. It includes a thrust ring 100 with a first receiving groove 110 and a plurality of fixing posts 200 arranged circumferentially and at intervals along the thrust ring 100. It should be noted that the thrust ring 100 is a conventional component in a motor, and the cross-section of the thrust ring 100 is annular. There can be 18 fixing posts 200. The number of fixing posts 200 is not a limitation on the number of fixing posts 200. It can also include other numbers of fixing posts 200, which are not particularly limited here.

[0030] Specifically, multiple fixing posts 200 are screwed to the thrust ring 100, and a portion of each fixing post 200 is located within the receiving groove.

[0031] The diameter of the first receiving groove 110 is larger than the diameter of the stator coil 300. When the stator coil 300 is assembled in the first receiving groove 110, a gap is formed between the stator coil 300 and the end of the fixing post 200, allowing the fixing post 200 to move toward the stator coil 300.

[0032] In other words, by utilizing the setting that the diameter of the first receiving groove 110 is larger than the diameter of the stator coil 300 in this embodiment, the stator coil 300 can be assembled without damage, avoiding damage to the enameled wire of the stator coil 300. When it is necessary to fix the stator coil 300 in the thrust ring 100, the setting that multiple fixing posts 200 are all screwed to the thrust ring 100 allows the operator to rotate the fixing posts 200 so that one end of the fixing posts 200 moves toward the stator coil 300, thereby fixing the stator coil 300 in the thrust ring 100 using the fixing posts 200. At the same time, since the multiple fixing posts 200 in this embodiment are arranged circumferentially and at intervals along the thrust ring 100, the multiple fixing posts 200 can fix the stator coil 300 from multiple positions, further ensuring the stability of the stator coil 300 fixed in the thrust ring 100.

[0033] Specifically, in this embodiment, each of the multiple fixing posts 200 includes a fixing part 210 and a threaded part 220 that is screwed to the thrust ring 100. One end of the threaded part 220 is located inside the first receiving groove 110 and connected to the fixing part 210, while the other end of the threaded part 220 is located outside the first receiving groove 110. It should be noted that a threaded hole that mates with the threaded part 220 is provided on the outside of the thrust ring 100. That is, rotating the threaded part 220 can drive the fixing part 210 to move toward the stator coil 300, thereby fixing the stator coil 300 using the fixing part 210.

[0034] To ensure the stability of the fixing part 210 during movement, in some preferred embodiments, the thrust ring 100 is also provided with a plurality of sliding grooves 130. Each fixing part 210 is slidably connected to the corresponding sliding groove 130. The plurality of sliding grooves 130 are circumferentially distributed in the thrust ring 100 with the center of the thrust ring 100 as the origin. By using the setting of the sliding grooves 130, the fixing part 210 can reciprocate along the extension direction of the sliding grooves 130, ensuring that the fixing part 210 can accurately move to the outside of the stator coil 300.

[0035] In addition, a hole 230 is provided on the fixing part 210. The hole 230 is used to accommodate one end of the threaded part 220. It should be noted that the threaded part 220 and the hole 230 are rotatably connected.

[0036] Since multiple fixing posts 200 are arranged circumferentially and at intervals along the thrust ring 100, when the first fixing post 200 is rotated, one end of the first fixing post 200 will apply a thrust toward the stator coil 300. Since the operator cannot accurately judge the fixing effect of the first fixing post 200 on the stator coil 300, it is easy to cause the first fixing post 200 to be over-operated, resulting in the stator coil 300 being offset during assembly. Therefore, the assembly fixture in this embodiment also includes a positioning block 400, a fixing block 500, and multiple connecting parts 600.

[0037] Positioning block 400 and fixing block 500 are used to be set on opposite sides of stator coil 300, and multiple connectors 600 are used to pass through through hole 310 of stator coil 300 to connect positioning block 400 and fixing block 500.

[0038] The thrust ring 100 is also provided with a second receiving groove 120 that communicates with the first receiving groove 110. The second receiving groove 120 is used to engage a portion of the positioning block 400.

[0039] Specifically, the first receiving groove 110, the second receiving groove 120, and the thrust ring 100 are all concentrically arranged. Utilizing the positioning block 400, the fixing block 500, and multiple connecting pieces 600, when assembling the stator coil 300, the positioning block 400 and the fixing block 500 can be first installed on opposite sides of the stator coil 300 via the multiple connecting pieces 600, specifically at the bottom and top of the stator coil 300. After the positioning block 400, the fixing block 500, and the multiple connecting pieces 600 are assembled with the stator coil 300, the stator coil 300 is assembled into the first receiving groove 110. At this time, the positioning block 400 will be located in the second receiving groove 120. The second receiving groove 120 restricts the positioning block 400, thus limiting the left and right offset of the stator coil 300 when rotating the fixing column 200. This effectively ensures that the stator coil 300 will not shift when rotating different fixing columns 200.

[0040] It should be noted that the connector 600 can be made of bolts and nuts, and the positioning block 400 and the fixing block 500 are provided with assembly holes that mate with the connector 600.

[0041] In addition, in some preferred embodiments, the depth of the second receiving groove 120 is smaller than the height of the positioning block 400, so that when the positioning block 400 is engaged in the second receiving groove 120, a portion of the positioning block 400 is located in the first receiving groove 110, and the diameter of the second receiving groove 120 is smaller than the diameter of the first receiving groove 110. By using the dimensions of the first receiving groove 110 and the second receiving groove 120 to limit the size, the first receiving groove 110 and the second receiving groove 120 can form a stepped groove.

[0042] In summary, the stator coil assembly fixture of this utility model, compared with the existing stator coil assembly methods, has at least the following advantages:

[0043] In the assembly fixture of the stator coil 300 of this utility model, by setting the diameter of the first receiving groove 110 to be larger than the diameter of the stator coil 300, the stator coil 300 can be assembled without damage, avoiding damage to the enameled wire of the stator coil 300. When it is necessary to fix the stator coil 300 in the thrust ring 100, the multiple fixing posts 200 are screwed to the thrust ring 100, so that the operator can rotate the fixing posts 200 and move one end of the fixing posts 200 toward the stator coil 300, thereby fixing the stator coil 300 in the thrust ring 100. At the same time, since the multiple fixing posts 200 in this embodiment are arranged circumferentially and at intervals along the thrust ring 100, the multiple fixing posts 200 can fix the stator coil 300 from multiple positions, further ensuring the stability of the stator coil 300 fixed in the thrust ring 100.
