[0053] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams. Example

[0054] See also Figures 1 to 4 , the figure shows a stator core winding tool, including a base plate 100, left and right supporting rotating mechanisms 200a, 200b and seven stator core jackets 300.

[0055] The base plate 100 serves as a support base for the entire tooling, and is used to install various mechanisms or components in the tooling, so that the tooling can be placed on a designated working plane for operation.

[0056] The left and right supporting rotating mechanisms 200 a and 200 b are symmetrically arranged on the base plate 100 and are used to clamp the stator core winding body 10 .

[0057] The left support rotating mechanism 200a includes a left support seat 210a, a rotating shaft seat 220a, a rotating shaft 230a and a left rotating shaft sleeve 240a. The left support seat 210a is arranged on the base plate 100. The rotating shaft seat 220a is arranged on the top of the left support seat 210a, and a rotating shaft hole (not shown in the figure) is formed in the rotating shaft seat 220a. The rotating shaft 230a is rotatably mounted in the rotating shaft hole of the rotating shaft seat 220a, and the left and right ends of the rotating shaft 230a extend out of the rotating shaft hole. The left rotating shaft sleeve 240a is fixedly arranged on the right end of the rotating shaft 230a by fasteners such as fastening screws, and the left rotating shaft sleeve 240a is fixedly connected to the insertion part of the stator core 11 located at the leftmost end of the stator core winding body 10 through the left stator core pressure plate 250a.

[0058] Specifically, the left stator core pressure plate 250a is surrounded by the upper left and lower stator core pressure blocks 251a and 252a, and a left pressing groove adapted to the insertion part of the stator core 11 is formed at the connection between the upper left and lower stator core pressure blocks 251a and 252a. The upper left and lower stator core pressure blocks 251a and 252a are respectively fixed on the supporting end face of the left rotating sleeve 240a by fasteners such as fastening screws, and the insertion part of the stator core located at the leftmost end of the stator core winding body 10 is pressed against the supporting end face of the left rotating sleeve 240a through the left pressing groove, so that the left rotating sleeve 240a is fixedly connected to the left end of the stator core winding body 10.

[0059] The right support rotation mechanism 200b includes a right support seat 210b, an ejector shaft seat 220b, an ejector shaft 230b, an ejector locking screw 240b and a right rotating sleeve 250b. The right support seat 210b is arranged on the base plate 100. The ejector shaft seat 220b is arranged on the top of the right support seat 210b, and an ejector shaft hole (not shown in the figure) is formed in the right support seat 210b. The ejector shaft 230b is sleeved in the ejector shaft hole of the ejector shaft seat 220b, and the ejector shaft holes extend from the left and right ends thereof, and an ejector portion 231b is formed at the left end of the ejector shaft 230b. The ejector locking screw 240b is screwed on the ejector shaft seat 220b, and is used to lock the ejector shaft 230b. The right rotating sleeve 250b is fixedly connected to the insertion part of the stator core 11 at the rightmost end of the stator core winding body 10 through the right stator core pressure plate 260b. The ejector part 231b of the ejector shaft 230b abuts against the right rotating sleeve 250b during operation. The ejector shaft 230b in the right supporting rotating mechanism 200b can be moved and locked along the axial direction of the ejector shaft seat 220b to adapt to different numbers of stator cores 11 connected in series.

[0060] Specifically, the right stator core pressure plate 260b is surrounded by the upper right and lower stator core pressure blocks 261b and 262b, and a right pressing groove adapted to the insertion part of the stator core 11 is formed at the connection between the upper right and lower stator core pressure blocks 261b and 262b. The upper right and lower stator core pressure blocks 261b and 262b are respectively fixed on the supporting end face of the right rotating sleeve 250b by fasteners such as fastening screws, and the insertion part of the stator core 11 located at the rightmost end of the stator core winding body 10 is pressed against the supporting end face of the right rotating sleeve 250b through the right pressing groove.

[0061] Each stator core jacket 300 is correspondingly clamped on the insertion part of two adjacent stator cores 11, so that eight stator cores 11 are fixed together in series and form a stator core winding body 10. Of course, the number of stator core jackets 300 is not limited to the number in this embodiment, and it should be set according to the number of stator cores 11 that need to be connected in series. During operation, the stator core winding body 10 is placed between the left and right supporting rotating mechanisms 200a, 200b and is clamped by the left and right supporting rotating mechanisms 200a, 200b, so that the stator core winding body 10 can rotate around its central axis.

[0062] Specifically, the stator core jacket 300 is enclosed by upper and lower stator core clamping plates 310 and 320, and a clamping groove suitable for the insertion parts of two adjacent stator cores 11 is formed at the connection between the upper and lower stator core clamping plates 310 and 320. During installation, the upper and lower stator core clamping plates 310 and 320 are clamped on the insertion parts of two adjacent stator cores 11, so that the clamping groove formed between the upper and lower stator core clamping plates 310 and 320 covers the insertion parts of the two adjacent stator cores 11, and then the upper and lower stator core clamping plates 310 and 320 are fixed by fasteners such as fastening bolts, so that the two adjacent stator cores 11 are connected and fixed together in series.

[0063] See also Figures 5 to 8 The upper and lower winding gaskets 311 and 321 are fixedly installed on the left or right plate surfaces of the upper and lower stator core clamping plates 310 and 320, and the upper and lower winding gaskets 311 and 321 are formed with upper and lower winding guide inclined surfaces 3111 and 3211 at positions close to the stator core 11. The winding is regulated by the upper and lower winding guide inclined surfaces 3111 and 3211 to prevent the end of the winding layer from being suspended. The upper and lower winding gaskets 311 and 321 are arranged according to the winding direction.

[0064] The stator core winding tool in this embodiment also includes a rotation auxiliary stabilization mechanism 400, which is installed on the base plate 100 and is used to assist the stator core winding body 10 in rotating, thereby improving the stability of the stator core winding body 10 and ensuring the winding effect.

[0065] Specifically, the rotation auxiliary stabilization mechanism includes two annular pressure wheels 410 and a roller mechanism 420 .

[0066] Two annular pressure wheels 410 are axially spaced and sleeved on the outer peripheral side of the stator core winding body 10, and each annular pressure wheel 410 can be detachably fixedly connected to any stator core jacket 300 in the stator core winding body 10. Of course, the number of annular pressure wheels 410 is not limited to that in this embodiment, and should be set according to actual requirements.

[0067] The roller mechanism 420 is installed on the base plate 100, and is used to assist each annular pressure wheel 410 to rotate. The roller mechanism 420 includes left and right roller support seats 421a, 421b and upper and lower rollers 422a, 422b. The left and right roller support seats 421a, 421b are symmetrically arranged on the base plate 100 and located on one side of the left and right support seats 210a, 210b. The upper and lower rollers 422a, 422b are arranged between the left and right roller support seats 421a, 421b with upper and lower intervals, and the left and right ends of the upper and lower rollers 422a, 422b are rotatably installed on the left and right roller support seats 421a, 421b respectively, and the outer shaft surfaces of the upper and lower rollers 422a, 422b form rolling contact with the outer wheel surface of each annular pressure wheel 410.

[0068] When the stator core winding body 10 is wound, the enameled wire 20 will generate a certain pulling force on the stator core winding body 10, which is then transmitted to the winding tooling. Since each annular pressure wheel 410 is fixedly connected to the stator core winding body 10, they will rotate together during winding, but under the limiting effect of the upper and lower rollers 422a, 422b, the pulling force will be transmitted to the upper and lower rollers 422a, 422b via the annular pressure wheel 410, thereby offsetting the pulling force generated by the enameled wire 20, preventing the stator core winding body 10 from deforming during winding and affecting the winding effect. At the same time, since the stator core winding body 10 is continuously wound (the enameled wire cannot be broken), the annular pressure wheel 410 is installed in a detachable manner. As the winding moves, the annular pressure wheel 410 at the winding location moves accordingly.

[0069] The stator core winding tool in this embodiment further includes a rotating handle 500, which is mounted on the left end of the rotating shaft 230a and is used to drive the rotating shaft 230a to rotate, thereby driving the stator core winding body 10 to rotate. Of course, it can also be driven by electricity, for example, a driving motor is connected to the rotating shaft 230a through a transmission mechanism such as a gear assembly or a pulley assembly to drive the rotating shaft 230a to rotate.

[0070] The stator core winding tool in this embodiment further includes a wire guide mechanism 600, which is mounted on the base plate 100 and is used to guide the enameled wire 20 for winding. Specifically,

[0071] The wire guide mechanism 600 includes a wire guide rail 610, a wire guide pulley seat 620, and a wire guide pulley 630. The wire guide rail 610 is mounted on the base plate 100, the wire guide pulley seat 620 is slidably disposed on the wire guide rail 610, and the wire guide pulley 630 is axially disposed on the wire guide pulley seat 620. The wire guide pulley 630 reciprocates and slides on the wire guide rail 610 through the wire guide pulley seat 620, and can move with the winding.

[0072] In order to ensure that the enameled wire 20 has a certain tension, a tensioning mechanism (not shown in the figure) is provided between the lead-in mechanism 600 and the enameled wire pay-off drum (not shown in the figure), and the tensioning mechanism is used to tighten the enameled wire 20 so that the enameled wire 20 maintains a certain tension. In this embodiment, the tensioning mechanism can be a friction wheel or other tensioning equipment.

[0073] The working process of the stator core winding tool in this embodiment is as follows:

[0074] 1. Seven stator core jackets 300 are correspondingly clamped on the insertion parts of two adjacent stator cores 11, so that the eight stator cores 11 are connected and fixed together in series to form a stator core winding body 10;

[0075] 2. Two annular pressure wheels 410 are spaced apart and mounted on the stator core winding body 10, and fixed at the starting end of the winding;

[0076] 3. Place the stator core winding body 10 with the annular pressure wheel 410 between the left and right supporting rotating mechanisms 200a and 200b, and clamp it by the left and right supporting rotating mechanisms 200a and 200b, and make the outer wheel surface of the annular pressure wheel 410 form rolling contact with the outer shaft surfaces of the upper and lower roller shafts 422a and 422b;

[0077] 4. The wire end of the enameled wire released from the enameled wire pay-off drum is passed around the lead-in mechanism 600 and then wound around the winding starting end of the stator core winding body 10, and then fixed to the base plate 100 by fasteners such as screws or jackets;

[0078] 5. The stator core winding body 10 is driven to rotate by rotating the handle 500, so that the enameled wire 20 is wound on the outer peripheral surface of each stator core 11 in the stator core winding body 10. During the winding process, the annular pressure wheel 410 moves with the winding until the first layer of winding is completed, and then the enameled wire is cut off;

[0079] 6. Repeat steps 2 to 5 above to carry out the next layer of winding until the multi-layer winding is completed. Example

[0080] The stator core winding tool in this embodiment is substantially the same as the stator core winding tool in Embodiment 1, except that the driving method of the stator core winding body 10' is different. Fig. 9 The rotating handle 500' in this embodiment is installed at one end of the upper roller shaft 422a', which is used to drive the upper roller shaft 422a' to rotate. A transmission mechanism (not shown in the figure) is arranged between the upper roller shaft 422a' and each annular pressure wheel 410'. When the upper roller shaft 422a' rotates, the transmission mechanism drives each annular pressure wheel 410' to rotate, thereby driving the stator core winding body 10' to rotate. The transmission form of the transmission mechanism is not limited, and can adopt gear transmission, belt synchronous belt transmission, friction wheel transmission and the like.

[0081] Of course, the rotating handle 500' can also be installed at one end of the lower roller 422b', which is used to drive the lower roller 422b' to rotate. A transmission mechanism (not shown in the figure) is provided between the lower roller 422b' and each annular pressure wheel 410'. When the lower roller 422b' rotates, the transmission mechanism drives each annular pressure wheel 410' to rotate, thereby driving the stator core winding body 10' to rotate. The transmission form of the transmission mechanism is not limited, and can adopt gear transmission, belt synchronous belt transmission, friction wheel transmission and the like.

[0082] During winding, the two annular pressure wheels 410' are always located on both sides of the winding location, and only the stator core jacket at the winding location is subjected to torsional torque, while other stator cores are not subjected to force. Compared with embodiment 1, there is no torque transmission between the stator cores, thereby reducing the damage to the stator core caused by torque transmission, and also improving the winding effect.

[0083] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
